Only a 15.3? Untuned? There's some 5.0 tbi t5s that are running that.

Make sure everything is running right you should be way lower.

 

You dont know all the variable. maybe he has horrible 60' didnt hook up misshifted...dont know the exact running condition.

 

Hello,

some facts about my ´75 Chevy Monza:

Best ET: 14.379 @ 96.62 MPH (155.49 km/h)

# Chevy 350 from a ´88 van ("K"=LO5)
# TH350 automatic transmission, stock.
- Remapped ECM (I use the 8-position fuel/spark switch from Moates)

- MSD 6AL ignition in series with stock HEI
- Cold Air Intake w. K&N Cone air filter

- Hooker Headers 1 ½ ” Super Competition Headers
- Single 3” exhaust
- Electric fan
- 2.93 Posi rearend (from a ´76 Monza)

These don´t actually qualify as "improvements":

- OLD BF Goodrich Radial T/A 215/60-13 rear 205/60-13 front

 

My bone stock 89 with the tbi ran a best of 17 flat at epping new hampshire. Only had there the one time and did 5 runs.

 

OMG...I was married in 75 and that was one of my rides! Very cool... I never thought of dropping a V8 in it

 

.030" over 305

https://www.thirdgen.org/forums/tbi/...-bolt-l03.html

 

The Monza was offered with a V8 or a L4 version.
The V8, a 262ci is the smallest small-block ever made by GM.
Another thing to mention (sorry about the thread hi-jacking) is that the Monza was the first GM vehicle to use the torque arm rear suspension, which later was incorporated in the ThirdGen vehicles

Oh btw, my Monza weights 3130 lbs (1420kg), for ET-comparisons.

 

Bumping this old thread that way more people could post there times.

 

well hopefully by march ill be able to post a new time after I get this vigilante torque converter installed

 

What i wanna see is what people are getting with 350tbi since most that have tbi have a 305. Since im gonna swap in a 350 and thinking of going tpi but looks like a lot of hastle so i wanna see if theres good times with tbi too.

 

I have a CHEVY HIGH PERFORMANCE MAGAZINE somewhere, I don't remember year or month of issue, but there was a thirdgen, 88 I think...
It was 383 TBI (Turbocity) running mid 12's, It was making something like 420HP, What do you people think about this???

 

I would like to read the article about it. Wonder what they did for tuning and stuff.

 

damn if you ran that i wonder what miine would run, i have the same exact setup, but with a 5 speed, and flat top hyper pistons (around 9.8-10:1 comp), and a summit 1103 cam. on top of 3.73 gears out back

 

Only issue I recall was a 305 build. also I recall a truck 383 TBI with VG 1/4 mile times at a shoot out.

 

Ummm...NO!

We wonder what a properly modified & tuned TBI would run.
VA454SS has a BB pickup that is respectably limited w/GM TBI.
He has more stroke & cubes than I...but I have more cam, compression & head work.

OK now, back to the TBI cars...

 

I ran a 14.70 at 96mph in my 92 camaro last year with a custom tune, headers, cat back and edelbrock performer TBI intake and stock tbi, was an 89 truck 350, still had the stock cam and everything. pulled a 2.0 60' but was breaking up bad on the high end and needed to be tuned again and the spark plug wires were arking and makin it miss. it would of been in the low low 14s if i got it re tuned. since then i have added a lunati voodoo cam and valve springs and a carbed single plane high rise intake with 454 bbc injectors and sub frame connectors have not had it out much with new setup but the one time i did it twisted the body on the street untuned, an thats why i have sub frame connectors now lol. car should be good for 13s now

 

14.8 was the fastest in the previous car. With stock motor with a cam, ultimate TBI mods, chip, and headers and exhaust

New car is listed and havn't run it yet.

 

since this is updated i have ran a best of 14.23 at 93.3. But not i have bigger heads and the EBL so new times will be coming within the next few months

 

So am I still the only one that has ran 13's with the stock LO3 cam?

 

but that was with a carb.

Here it is and it was done with a 305 not a 383

 

I know I have a carb and not TBI anymore but I'm sure we can all agree that TBI is better than carburetors. I think I would have ran better than a 13.9 with TBI. But my times were on a cold day at Coastal Plains Raceway, which is basically sea level. And I have been drag racing for many years so I know how to get good times out of a car.

 

ran a 15.6 at esta ny in my firebird 305 tbi ram air header back hurst short throw t5 3.08 rear gears 35psi in backs

working on a 355 tbi swap for this summer

 

IMO NO...Except my L03 cammed L03 was wrapped in 5,500 lbs of unaerodynamic greatness. In a lighter F-car it would have gone 13s easily.

well i know tbi runs a lot better than a carb and always will. as for all out top end 1/4 mile power. no. a properly tuned carb of at least a 650 and a better intake can and most likely win out. my tbi doesnt seem to have the top end that the edelbrock performer and a 650 holley had.

 

That is where you are wrong. A single plane manifold and TBI will outperform a carb of the same size EASILY. A 660 cfm BBC TBI on a single plane manifold pulls strong up to 6,500+ RPM on a 350.

 

and a 650 carb on a single plain will not run as good? and a carb will not run that high of rpm? i believe you are wrong in that area. we can argue this point to death. it has been and always will be. now is pulling to 6500+ with a stock cam?

 

Whoever said I pulled to 6,500 with the stock cam. I had a XFI grind cam and a set of lightly ported ZZ4 cams.

TBI will make ALOT more torque from idle-3,000 rpm than a carb on a single plane. The TBI will also atomize the fuel better, giving you a cleaner burn and more even air/fuel mixture distribution, and guess what more HP. I never said a carb wouldn't pull the RPM, just that a TBI of similar size would pull up to 6,500 and still show better power numbers.

 

ok that is what i was wanting to know.

a properly set up set of heads and a cam along with an intake with a carb on top can and will beat a tbi. if we are talking about cams and heads then to me it can go either way. a really good carb person, a good set of heads, an intake to match along wiht the right cam can and will outflow a tbi all day long and outrun it in the 1/4 mile every time. heck man the have 1050 carbs. although they wont be needed. if we are going to take a stock bottom end and everything on top is going to be modified then a carb will win in the end.

if you are willing to give a little horsepower. add a ton of runability. ease of use AFTER A LOT OF TUNING then yes a tbi will be great. but for all out 1/4 mile running? a carb and mods will win.

 

Acceleration enrichment can be dialed in much more precise with TBI, improving the rate of acceleration which makes a tremendous difference...

 

that all depends on who is tuning the carb. and if tbi is that much better how come arent they using them in racing.

 

Your missing the point, tuning pulse width and SA is way more precise than swapping jet sizes and power valves. Precision is everything...

 

Think of what you are saying. Put up any two barrel carburetor against any two barrel TBI system, and tell me who do you think will win? Now, put up any four barrel carburetor against any 4 barrel TBI system and tell me who do you think will win...?

 

again it comes down to who is tuning it. i will say this again and again. there are people that can tune carbs to run just as good. darnit if tbi's were so darn great show me an nhra drag car with one. its in the tuning. that is what i am saying.

you have modded an engine to run with tbi. now stick a tbi on an engine without a cam set up for it. lemme know how it will run. what you are saying is that a carb cannot be tuned to run as good as a tbi engine? you are lying to yourself if that is your belief.

oh and by the way. the fastest cars on this site are NOT TBI INJECTED.

and this is the quick 1/4 mile thread.

 

The same can be said with the factory TBI. Nobody has really tested its' limitations in a 3rd Gen yet. As for TBI not being competitive, again, the Holley 950 TBI system can generate more usable power than a carb with the same cfm rating ever could, while remaining completely docile on the street to boot. As for why people prefer to use carbs, well there are two reasons, the first, carbs are cheaper to buy as opposed to throwing your money down on a Holley Commander 950 system, and two, people nowadays prefer port injection.

 

This is the "quick 1/4 mile" thread FOR TBI's, IN the TBI forum...

 

... maybe one day after I run my nine second pass with the 305 I will restart my TBI quest. I shelved it after I modified it and never looked back. Hmm.

 

man dude it all comes down to preference and ability. along with money. the have carbs that can flow 1100 or 1200 cfm.

the point i am trying to make is an engine can be built to compliment one or the other. we can build from 200 to 3000 hp carbed engines. and im sure we can build high horsepower tbi engines. but for right now a properly built carb engine will win out whether or not they have pushed the limits of the tbi. what is the biggest tbi?

the MAIN POINT WAS 1/4 MILE FAST. if people are going to argue which is fastest and have all kinds of mods from bottom to top in this day the carb will win. once we push the final limits of a tbi system we will know the truth. dont get me wrong i love fuel injection. i love the fact that nascar has went to it. top fuel dragsters use a form of it. but we are talking street cars. so if we were to put this in perspective carbs have been around for longer than i have been alive ( 43 years ) and have made awsome power. dont get me wrong i love fuel injection. atomization is great. direct injection trumps it all. this argument has always and will always go on. fuel injection will always-always-always run better than a carb in all manners of engine runabilty and control. the carb has always outrun fuel injection for the most point in a straight line. so this all boils down to tbi. stock? slightly modded or carzy modded.we dont see too many 2500hp tbi engines. we will. some have prolly made it. if i had the mney i would love to blow out an 800hp third gen with a single tbi. kick a 100,000 dollars cars *** and open the hood to an open element tbi engine and say HA!!!

especially that well tuned c6 zo6 vette in my neighborhood that even revs at me. can you imagine the look on his face if he were beat by my BELOVED THIRD GEN and then open the hood to a small block with a single tbi on it. now that is friggin priceless. maybe one day.

 

yes sir it is a tbi 1/4 mile quick thread. and someone ran a 13 with a carb in which i pointed out.

by the way how did that tbi run.

 

Wow, for being one to completely change the subject. I am talking on a stock block 305/350 the BBC TBI will out power the carb, ANY carb with a little tuning. A stock block 350 might make 500 HP and still be streetable to any extent.

Perhaps before running your mouth so much on the limits of a TBI 305, you should search my TBI 312 and its track passes. Not saying it is the fastest by any means, but it is quicker than your average "race carbed 350".

I hope you realize that they highest HP production gasoline fueled engines ever made where setup with the mechanical equivalent of TBI. 4362 CID and 4,300 HP @ 2,800 rpm. Fed by a single pressure injected carb (mechanical TBI)

 

wow now im running my mouth. i tell you what. you show me a 1200 hp tbi engine and i will shut up. show me one. i know of several 500, 600, even 700 hp small block engines. this goes back to the tbi is god. when you show me a tbi nhra engine ill kiss your ***. run that.

and darnit AGAIN this is a 1/4 mile fast thread. show me an 11 second tbi engine. show me a ten second tbi engine. when you find them show me an 8 second tbi engine. when you do that then tell me im running my mouth.

 

That is not the original subject matter and for the record I went 12s with a 305 and it had a single TBI unit on it. Think of what Dual Bored 454 TBIs, 2.3" each would flow like with 4 injectors feeding it, around 800 cfm each. 1600 cfm on a tunnel ram, seems like it would feed 8-9 second engine to me.

 

I guess I won't mention the 406 dual TBI fed engine that I tuned for a 39 Chevy street rod. It had dual 2.8 TBI throttle bodies on it, because the small block ones, flowing over 1100 cfm without any form of progressive linkage were quite simply too much to control in that light car. Car went 11.40s @ 122 mph with two tiny little 2.8 TBI units up top.

 

...now back to quick 1/4 mile tbi combos! need to figure out how to make one fast for myself in the future.

 

this thread got a lil heated..i love it!

 

Well since my car went to the track last, I have added a ton of goodies to it..It ran a 15.3 at 89 mph with just a cat back, and a 305...Now it is stalled, new tranny, all new suspension pieces (UMI) CFM Bored TBI, eddy intake, eddy headers, msd coil, lots more..Should hit 14's pretty easy....Have a built 383 coming for it in a month, or so, but it will be carbed..Thanks to all for the replies to my post....Tom

 

going carb'd eh? sweet. i may have done that a long time ago if i didnt live in california

 

i ran a 13.5 at a mile high at 113 with corvette heads lt4 hot cam headers full 3 inch cat back and 3.23 gears and a turbo city chip with a procharger at 8lbs car dynoed at 375 rwhp i also had a really crappy launch

 

procharged L03? with an LT4 hot cam? with that MPH it should be faster you probably had a horrible launch

 

not an l03 its a l98 and yes very horrible launch and again i was at bandimere which is a mile higher than sea level
