Does anyone make a tbi supercharger? maybe one for a truck

 

Yes, I believe Vortec and ATI have kits that can make this work. All they do is attach the bell they use for carb applications to the TBI unit. I called and talked to ATI about it one time, and they just send the TPI kit, along with the bell and the connections needed to hook it up.

BTW Where do you live in Fairfax?

i'm pretty shure vortch makes a blower for 305 tbi, i used to have a part # for a ablower form either them or someone else in the summit catalog, but i can't find it anywhere. call summit and ask them, they will be able to give you the part # 1 800 230 3030.

by the way i also live in fairfax,va in the burke/fairfax city area, where you guys from??

 

I live right by robinson high school, kinda near 123 and braddock.

 

Turbo City has what you want. I saw it in their showroom. I saw a version that had a huge aluminum shroud that contained an intercooler that mounts on the TBI. Their catalog also has one in it. Unfortunately for me, not CA smog legal on a Camaro, only a truck. 8^( good luck, Lon.

 

Any idea on prices guys? I am pretty interested.

To damn much probably. Aren't aftermarket superchargers around 2500.00? Seems like you can get a decent 350 for that price and still be able to waste a Supercharged TBI 305

roots style chargers are $1500

 

Thats one of the cheaper chargers I have heard of then. Aren't they in summit for around 2500.00? Anyways, I just don't think they are worth it on any 305, TBI or TPI.

91BIRD305 u really think a mild 350 can take a supercharged 305????? lol I highly doubt it. Dude u really need to give these motors a little more credit.

Just because an engine is supercharged, doesn't mean it's gonna be fast. I researched supercharging my 350 for a long time. To run a good amt of boost (8-9 lbs) there is so many engine, fuel system, and computer mods to be done. On top of that you're really not going to get everything outta an s/c without a blower cam. So if a 305 is supercharged right...then no a mild 350 couldn't take it. Like anything else, it all depends on the engine and the engine application.

 

Its not that. Its that it will beat a stock 350 no problem. But if I had a highly modified 350 against your 305 Supercharged TBI then I know I would beat you. Cause when you start out with 170hp and lets say you add on maybe 100hp with that charger some how. That is 270hp+some mods. Which would max you out around 300 MAYBE. This is an extreme hp number for a 305. All I have to do is spend 2,000 bucks on a 350 HO w/ 330hp and 380lbs of torque. And I would beat you and I would have lots of change left over and you wouldn't. Better to spend the money on a 350 and then maybe down the road when u get more money to supercharge the 350 and you will make a crap loud more hp than the 305 ever could. Personally, I would never go with a supercharger. Why spend 1500-2000 when I can spend 600.00 and get a 125-150hp shot of NOS. Again, have change left over and I could swap it anytime onto my 350 when I get it. More hp and more money. Even better on your engine. With a charger it is always putting pressure on your engine, with NOS its more like insurance; only use it when I need to and only put stress on my engine when I have to.

by the way im planning on getting a 350 with a holley tbi

 

anything you can add to a 305 you can transfer to a 350 shortblock when the time comes. They are all small block chevys. I don't know what you guys are bickering about.

------------------
AOL IM: superGRtaz

Didn't I already say that?

 

You can get a Weiand super from Summit for about $1250ish but when you add all the "rest" (pulleys/brackets/lines/help/etc), it'll be $1500 minimum. These are smaller blowers but are perfect for the street daily driver and add about 30-50%. DONT'T work with all accessory packages, that's where the extra money comes in. You'll need to fabricate/buy stuff...

 

well this whole 350 being so much faster than a 305 thing doesnt wash with me. Compare the stats, the 350 tpi is only 10 hp more than a 305 tpi. 10 hp is not worth the effort to change a motor. If ur only getting 10 hp more its not gonna equal that much more if it where supercharged. Ur gonna get the same % of increase either way. That zz4 crate motor that everyone seems to warship is only 330 hp on certain aspects. Thats with a certain intake, exahaust, and carb and that is only at the crank. Not to say it isnt fast but dont think by bolting a 350 in ur car its all the sudden gonna run all that much faster than a 305. Like stated earlier they are both small block chevys.

there really isnt to much u would have to do with a 305 to get a super on it and get some nice increases. The weiand roots type blower is 1400$ with all hardware and works with serpintine belts. Drop a nice cam in there and ur off. I dont see what all the fabbing is all about, The only other thing i could see is larger tbi unit and maybe a custom prom.

BTW if a factory eclipse motor can handle almost 20psi y couldnt a motor that twice the size?

what i meant to say is, if the 4 cyl motor in the talons and eclipses can handle 20 psi what makes u think that a motor twice its size cant handle half the psi?

 

ONEFINE8T9, The ZZ4 is rated at 355hp and 406lbs of torque. Now I would choose that engine over a 305 ANY DAY. What I am trying to say is that I think it would be a lot better if he just got a 350 like a 350HO or ZZ4, and then did his superchargering stuff. And what are u talking about only 10 more hp? The 305 TPI had 205hp and the 350TPI had 245hp. Hmm, do math. Thats more than 10hp and that isn't even including the differnce between 305TBI which is 170hp. So that is a big difference in horsepower. I just think it is more logical to get yourself a nice crate engine like a 350HO,ZZ4, anything that is 350 or bigger and then do the supercharging, cause with any of the 350's I mentioned he will be making a lot more HP then he would with a 305 tbi with a 30%-50% increase in hp from a supercharger

my thoughts on the supercharger issue are these, I personally would go with a roots style blower with tbi
mainly due to the fact that its low cost
and tbi wont do so well with a blow through design supercharger like a vortech or paxton because as pressure increases, fuel condenses in the manifold, granted, you could make a tbi centrifugal setup work very well, but why? with multiport you can reap all the advantages of an intercooled super charger setup with none of the downfalls.

So if i really wanted a cheap supercharger id go with the weiand roots blower thats made specifically for late model chevy trucks with tbi. Shane buss actually purchased this model and put it on his firebird, it works with the serpentine setup and im pretty sure its under 1500 dollars and its a straight up bolt on deal.

As for 305 vs 350, what some of you are forgetting is the great mover... TORQUE, somethihng the 305 will always be behind when compared to a 350 when comparing the same modifications. Lets not forget that 305 heads or 350 heads on a 305 cannot flow the numbers necessary for big power unless of course you wanna spend the cash on trick flows which will allow you to run big valves on a 305 but theres no point you could have gone to a 350 and still made more power.

I wouldnt be looking at superchargers for our 305s just yet, these motors are quite pathetic, and the gains realized from a supercharger are probably comparable to just regular old fashioned mods like cam, heads, manifold, exhaust, gears which can all be done for cheaper than a supercharger.

about these little motors taking tons of boost, thats because they are 4 cylinders. Im no 4 cyl expert but I was talking to a guy heavily into 2.2 mopar turbo motors and alot of this is simply because these 4 bangers come with forged internals AND something about the cranks being loaded differently to where the bottom ends are very resistant to destruction. Perhaps because they are loaded only up and down against the mains rather than to the sides? i dont know, but i know the main thing is that those motors are all forged internals from the factory and ours are not since they can squeeze the same power out and more torque without such high engine stress


Pablo

 

Yeah, but could a supercharger actually make our 255lbs of torque higher than any of a crate 350 which usually is around 380-405lbs of torque?

Uh

topfuel dragsters make a couple thousand ft/lbs of torque because of superchargers

the sky is the limit.. or how much you are willing to spend

take preston smith with the 86 iroc 305 TPI auto
the auto lb9s didnt make much more torque than what we make, but with supercharging, and proper parts selection, that car ran low 9s (with a 305)

 

Dude, where is this car and this time slip. That is amazing.

The 305 tpi had 235 horsepeower in 91 and 92.300 or 320 torque something like that.seems to me like a 5 speed 92 305 tpi would beat an auto with only 10 more horses.

My car is currently a TBI. I plan on converting it to TPI before supercharging it. But according to what I read, a supercharged 305 TPI is supposed to push 300+ hp. Not bad... I think it was the same HP as a new T/A. It lacked torque but oh well, I dont think a SC305 TPI is bad at all..

SEE PEOPLE! Now look. He runs a 14.569 with a supercharger! Stock 4thgen Z28's run those times and he has 3:42 gears. All I am trying to say is that if I was you, I would get a crate engine from some GM performance people THEN supercharge it. I guarentee you will be pushing 12's low 13's for sure and it will be MUCH less of a hassle. Plus, when you get the engine in (and convert to whatever you want or stay, I personally would go with what the manufuatuer used on the engine) and you will be running high to mid 13's with like a ZZ4 or something similar in size and power. Then when you supercharge it you will be running much LESS ET's then before. I don't understand why this is such an issue. 350's are better than 305's and supercharging a 305 is just a waste of time and a hassle unless you plan on converting it to a 350 in the near future like our supercharged friend above this post. Get a 350 crate engine (not a stock 350 out of a thirdgen that you people keep talking about) drop that badboy in and then start your blower project! You will be much more satisfied with this route.

I hate to agree with 91bird but im forced to.

btw the 5 speed cars had more horsepower because of a better camshaft and preston smiths car is obviously, nowhere near, not even close to stock. TPI isnt the magical induction system it has lots of problems too. For the technology available to us now your best bet is a single plane mpfi conversion and if you really wanted perfection then it'd have to be sfi. Remember though an induction system wont make you power, and n/a, tbi is more than adequate for most applications

theres a reason i have this

still sitting in my garage and not on my car

[This message has been edited by Pablo (edited October 14, 2000).]

 

Wow Pablo, we finally agree on something.....What a crazy world we live in. But I still think Carb more than supports small blocks the best. But that is my opionion....possibly not the truth but I think it is.

i am sorry did u say 14.5 on supercharged 305?? ok dont tell me u guys are gonna start saying that a 305 tbi wont run past a 14.5 after a supercharger. I mean r u seriously gonna tell me that u havent seen 305 tbi's with light mods in the 14's. U must have some serious problems if u cant break 13s on a supercharged 305. Remember 350 and 305 are almost identical other than bore. Take 2 of the idential blocks, one 350 and the other 305,supercharge them and look at The difference in hp #s, They arent gonna be that much different. Sure u might have a little more in a 350 but thats just common sence.

YES i did say 14.569 on a supercharged 305 TBI. If you look carefully, the only major mods I've done to the car besides the Paxton are, exhaust, gears, and posi. THAT'S ALL!
The engine and trans are still 100% STOCK. And as we all know (or at least should) the stock heads and cam in a 305 TBI are worthless!!!! The heads don't flow for ****, and the cam might as well be a round solid rod!!
Now If i got a 2800 rpm stall converter, and shift kit for the trans, I'd most likely be near 14.2's, then if I got some heads from a 305 TPI ported and polished, and a cam from a L89 or the likes, I'd might be around 13.5's or better. If I were to get some better aftermarket heads and a blower cam, I might dip into the high 12's, all with the stock intake, but if I upgraded that to a good carb intake w/TBI adapter then I'd see mid to high 12's for sure. And all of that isn't taking into account any custom programing, so there's a good possibility of low 12's maybe even high 11's. I don't know...we'll just have to wait and see if I end up doing it or moving on to a newer LS1 powered 'bird. Only time will tell.

Later,
Mike

 

HAHAHAHA, FINETA, Your a real funny guy. Yeah dude, I am going to tell you that I have never seen a 305 TBI with light mods in 14's. HAHAHAHA, The only 14's 305 tbi's I have seen are the one's that have internal work like cam and heads or blowers.


You must have some seriously problems if you think all you have to do is throw on some light bolt ons and a blower to get into 13's for a 305TBI. Stock it starts out at 170hp w/ 255lbs of torque. Dude, your right, a few bolt ons and a 30-50% increase from a blower and you would be way above 300hp. Bolt ons add maybe 10-15hp if your talking about open element,spacer,pulleys etc. A blower would give you maybe 50-70hp. Ok, so far we are around 255hp-270hp with a blower and some bolt ons and an empty wallet for wasting your time in playing with 305!


Commone sense is that a 350 will make not a "little" more hp than a 305 would with those mods. It would make a Sh*t load more. Think about it. This guy goes out and buys a 2,000.00 crate engine. Lets say its the 350HO from GMPP. Now that engine is making 330hp and 380lbs of torque straight from the factory. Hmm, no blower on that either. LETS PUT ONE ON! 50%-70% increase. 380hp-400hp now. Hmm, where are we at with that 305? Oh yes, 255hp-270hp, unless you think that a blower will make more hp on a 305 than a 350. oh and a stock Z28 can still beat us. Hmm, wonder which is a better path?

Are you guys forgetting that 305s go 200k miles+ EASILY and most people aren't due for a long block swap FOR A LONG TIME? Of course a 350 will wipeout a 305, but this "Just get a 350" crap isn't cool. Most people want to know about what they can do NOW, not in a couple years when its time for a new engine. They can do exasut, heads, cam, 1.6 rockers, gears etc.

12 year old kid? Motor Trend? Dude, I am 19 and I don't even read motor trend. Those stuff were just estimations and facts. Estimation of hps and facts on crate engines and blowers. And when u say "little mods" u aren't fooling me. Who else around here thinks "little mods" are cams & gears. Dude, your a joke. Those are big mods last time I checked. Mods that increase peformance greatly are big mods or just mods. And as for combination of my mods, my mods are fine and my car is very fast for a 305 tbi. Not as in a V8. I am sorry but when it becomes a victory to reach 14's and nearly impossible to reach 13's and 12's if you want to burn a hole you your wallet the size of the grand canyon then yeah, I consider that to be slow for a V8. I am sorry, but when I see engines now that runs mid to high 13's stock it makes me think. Hmmmm, maybe I outa upgrade instead adding all this junk to an engine GM doesn't even make anymore for obvious reasons. Sure, I added on mods that can be swapped over to a 350 and I stopped. Cause I don't want to waste my money on something that I can't swap over to a 350 cause unless you want to just fiddle with a 305 all day and try to make it run 13's and 14's (which is ridiclous) then go ahead. Me on the other, I am going to start over with a crate engine and work from there with NOS, rear end and tranny stuff. Go ahead and stick with doing your 305 project. I'll call you when your done and I hope one of your mods was door pins cause I would blow them off anyday.


Ok, I just did. And personally, a supercharged crate engine sounds better. As if looks better? i didn't know this was a beauty contest.

In all out honesty, I would never but a blower on a car. Why waste 1500 bucks for 50-70% increase when I get a 600 bucks Nitrous kit and choose how big of a hp shot I want and use it when I want and when I don't want. Personally that sounds better to me.

ok...concerning the 305 vs 350 thing...

take a 305 and a 350. put in similar pistons, heads, and cam, and the output will be similar. the 350 will have more, but still similar. look at the difference in cams, heads, and intake/exhaust on the L03 and the L98. no wonder they are so different on teh dyno! any gearhead worth his subscription to Hot Rod should be able to tell you that you can't compare these two engines any more than you can compare apples and frieking oranges. they are just NOT EVEN CLOSE TO EACH OTHER. no other way about it.

about the blown 305 vs. new 350 thing...

ok, spend like 2-3 grand on a blower for an L03, or spend 2-3 grand on a crate engine...?

blown (stock) L03 - 300hp MAX
350 crate motor - 330hp

AND..you SYILL have a stock L03 internals...2 bolt main...peanut cam...crappy heads. looks like its at about the maximum output before you break teh motor open to beef it up.

hmm. heres another thing...L03 with mild cam, head work, blah blah blah. (so that it's internally equivalent to a new crate motor)...

modified L03 with blower - 350hp ??

BUT you spent like a grand to 1500 on mods, which if you spent on the new crate motor, could have you into the 400hp range.

just think about it...it just doesn't make sense to throw a blower on a STOCK L03. i could see a modified 305, but shy a stock L03? thats like getting a brand new paint job on a 1984 Yugo...just doesnt make sense to me.

ok well figure in the new crate motor and than add the 1500 for a supercharger. But thats all good on proces but who is gonna put this crate morot in for this kid. Not everyone on these boards is qualified enough to swap out a 305 to a 350 let alone a 350 that isnt even desinged for cars newer than 76. Who was talking about LO3 to L98. Lets try LO3 to LO5? the #s would be very similar. Now by saving the money for a new motor u can get a super on the LO3 and still have close #s to the LO5. So u can get into a car with a 305 that will eat most 350s up for dinner and be into it half of a supercharged 350.

LMAO aright I ll let u think that so u dont have to cry all about it, BTW u talk about saving money.... if u change rear ends again wouldnt that be ur third time doing the job?? Ya i really need money saving advice from u

 

i wish my budget let me call gears and cam a little mod, btw **** motor trend

[This message has been edited by 1989CamaroRs (edited October 15, 2000).]

 

I agree with u 1989CamaroRs. As for me swapping the gears, I had to. And just for the record I paid 50 bucks for the gears and 100 bucks for the posi. So there is your money saver. (170.00 labor) As for this stuipd fued over which is a money saver. I will say it again. If you REALLY wanted to save money. I would get NOS. NOS is 600 bucks compared to the 1500 for the supercharger. NOS you can choose your hp shot and use it whenever you want. And another thing. The only reason they say it for pre-76 cars is because of emmision laws. And if this kid goes any way either blower or crate engine he is not going to pass emissions no matter what. So that doesn't even matter. As for the LO5. Do u know what LO stands for? I think I told you before. LOW OUTPUT. Were not comparing these sorry excuses for V8's anyways so lets leave LO everything out of it. Were talking about big mods anyways. And I say a crate engine or any will always be the best mod. By the way, do u think this guy will be able to install the supercharger but not an engine? I think they are both equally difficult to do. I have never done a supercharger before but I have seen it on HP TV and it looked pretty difficult (and they always make thing look easy, LOL) So installtion isn't an issue either. Again, I wasn't talking about cheapest mod. I am talking about the 2 being almost equal in price. Supercharger 1500-2000 Crate Engine 2000-2500. So personally, I would want a 300hp+ to start with than 300hp to end with.

 

I like how you act as if 13s were just totally unreachable unless you really step up the cubes. If we had non computer controlled cars 13s would be a cam swap and slicks away ON the 305

i know for a fact youd soil your pants if you went for a spin in my 305 powered car thats for sure

GO WITH SOLID FUEL ROCKET OR TURBINE
THATS WHERE THE REAL POWER IS.
how bout closing this one and letting this guy just email one of the following people?
didnt the last board get clogged because of arguements from people who thought they knew what they were talking about.
Seriously, if you REALLY know what you are talking about type, otherwise, go read a book and learn.
<--see the number of posts, i been here since the begining, but i like to listen, instead of talking about something i havent trained in or studied.
sorry this kinda thing just gets to me.

well said sunuffel. I wish the internet was around when the 305 TBI came out. there would be much more progress and less speculation now.

 

ok well this arguemnt is really pissing me off. OK i can sit here all day and night (91bird305) just to prove my point but i dont really care n e more. I cant stand to argue with someone who has no clue what they are talking about. To me 91bird u remind me of a junkyard mechanic. Someone who would sacrafice a decent 305 for some ratty old 350 just for the extra cubes. Ok well u go ahead with ur 350 (that isnt even meant for ur car) Ur poor choice of mods and all ur little stats that down play everything these cars came with. I dont care n e more.

 

you want to talk about perfomrance. you bitch about cubic inhes. and you crow about GMPP crate engines, then shut the FU*K up and step up to the plate with the big mama jama 502 crate motor....more power MWHAHAHAHA

Also who really gives a damn if he wants to supercharge his 305 or you want to put a 350 or I want a gian turbine engine, Hot Rodding is about doing what YOU want to YOUR car, not following some preset guidlines.

I'll bet you wish you had a supercharger on that 305 of yours untill you got that 350 installed so that 5.0 didn't beat you last time huh?

Bottom line: Pull up next to him at a light, and when it goes green the Sh*t talking ends.

1320 never lies.

 

Correct me if I'm wrong, but in order to realize the full potential of a supercharger,a hi-performance cam is a must.Think about it; If you are introducing a ton of extra air into the engine via the 'charger, you need a way for all that air to come in and then escape. A higher lift and longer duration cam will open the valves more and help let in all that extra air the supercharger is pushing, and expel the spent gases more efficiently.Am I correct? So if no other mods are to be added, at least change the cam and exhaust system.

 

Ok, I think everyone has said enough in this post. We have heard from both sides off the story.

1. Some people think supercharger

2. Other people think crate engine (not junk yard 350, would never touch them thats why I said crate engine not junk yard engine and my combination of mods would smoke yer peg leg 3:73's anyday )

So lets close the post with that. Whoever is reading this (I think 1989CamaroRS left a long time ago) can decide with the information here. But if I was you, go ask mechanics at speed shops or mechanics that have been in the business for a long time. They would really know because they have probably seen both outcomes. Other than that I think its time to close this thread pablo. Oh and Pablo...yours isn't a 305...its bored over remember....HAHAHA. Ok, so lets have no more said on this. Its getting old now. The horse has been beaten to death so bad that I don't even seem him anymore. LOCK ER UP!

ya really i just asked a simple question that could have been answered in a few posts

 

I know 1989CamaroRS (what is your name, LOL) I am sorry man. Like I said in my last post. Lets just lock it up and if I was you I would go ask a mechanic from like a speed shop or someone that has seen the outcomes of both of these decisions. They would know for SURE. Or e-mail people that have done it. Look above. Z28Boy (z28boy@twcny.rr.com) has done the crate engine swap I have been talking about and Blown 305 TBI (phoenix138@prodigy.net) has done the supercharging thing that ONEFINE8T9 has been jabbering about and Blown 305 TBI even has the 1/4 mile time u can probably expect to have. I am really sorry about this. Shouldn't have brought this arguement to this thread. I am trying to close it up now. Pablo where u at?
