very informative i must say


http://www.goingfaster.com/spo/modthel03.html

yes, the site people love to hate.

why?

Becuase TBI's dont break the 13 barrier and that site talks like they are rocket ships with a few turns of the wrench and mabye $50........ flame suit on...... make sure you run 14's before you try to flame me :lala:

lol..huh? i was just posting info i thought some people would find interesting reading because i did..........dont know what your flaming comment is all about

you asked why people "love to hate" that site............. I told ya why!

Wow, first post Ive seen on here in hieroglyphics

allrighty then

ok, i run 14's, have for a long time. what are you basing you position on? a bunch of guys have gone 13's with power adders, we have a formula that looks like 13's can be done n/a for cheap, and a ton of guys are starting to run in the 14's with simple stuff.
you may want to look into tbi before you make such statements.
that site has some very strong tech on it. the gains sound a little exaggerated to me, but the tech itself is rather solid.
i don't klnow what the story is with your car, but a lot of guys around here are making huge gains for $50. read a few tech articles and look at people et's and you will see that.

humm... ImportsRsloths you have a 350.. and your saying run 14's or not to talk.. and are you running 14's? if so i think thats pretty sad figuring there is 305 TBI's running 14s out there, seems like you sould be running a 10 flat in the 1/4 since you have the all "mighty" L98 because you have the displacement factor... whats wrong with you? why you so slow?

edit.. sorry i forgot you dont only have displacement but you have TPI

<......................slips out the back door b4 he gets in more trouble, id love to chat here but im on probation

Yeah that site does and this forum also has some very knowledgable people that know how to actually mod their engines for power. Maybe someone on this forum could teach you how to make some power.

Glad I have your permission.

TBI is ok, not great. That site is from a total bench racer.
My current theroy is NA TBI hits a brick wall around 13.5.
Someone
please prove me wrong.

Boys seriously.......... I havent taken it to the track as im pretty sure my sig says....... Im really hoping for high 12's... that will all depend on how good my porting job of the TPI intake manifold was, how good the car hooks up, and how good the Ed Wright chip works with the overall combo....... but if all those things work really well and work as a team, I dont see why it wont run low 12's........ Ive got some high perf. chevy magazines of combos with like that or with less stuff running low 12's, the one I based my mods off of ran 12.3's......... And i have a few better things going for me to...... But that besides the point...... IF THIS CAR RUNS 14's I WILL BE PI$$Ed..... ID PROLLY GO GET A TBI SET UP and see if i could run 15's


And for NJ SPEEDER...... WOW you said "and a ton of TBI guys are starting to run in the 14's with simple stuff."

YOU ACT AS IF OUR CARS HAVENT BEEN AROUND SINCE THE 80's ........... COME ON!!!

TBI guys read this site
http://www.mycar.net/mafb/registry/detail.cfm?id=201

NOW READ THE WHOLE THING......... and tell me why you like TBI better??????????????????? Figured I have to hook you up with some more "heiroglyphics" to get the point across..........

zz4 humm.. ok this has a zz4 too.. http://www.motorcities.com/contents/00G6H515800634.html .. well maybe not the same thing so nm :lala:

11.99 car .. zz4, Air Flow Research heads, hot cam, 1.6 RR, and a hell of a lot of money put in the tpi set up for it can flow better then porting out the stuff he just got, Drag-Launch Spring Kit , DragRadials, and a lot of other suspension modifications and etc.. why would this make me want tpi? i would expect him running those times.

what does it matter how long our cars have been around? a lot of motors lack development for a long time. particularly when there is a serious lack of aftermarket support for a specific format, that is the proble tbi has. othe rthan a half assed performer set up from edelbrock and a few parts from holley there is nothign for us to fall back on.
my question for you is what are you basing your position on?
it is very obvious that teh tech is being developed very well here to get these engines to run solid numbers with common mods and a little bit of thinking.
tpi has tons of development and after market parts support available, that makes your combo a lot easier.
tbi can go as far as anyone is willing to take it. plain and simple. the combos will progressively get more and more wild and faster every few months.
it is just liek the development of tpi, back when it was a mid 15sec turd that people woudl rip out of the car and replace with a carb.(anyoen else here remeber the ads for th e"new" iroc in 1985?). that all chagned when slp stepped in. we just have to develop our own tech, unlike the corporate backed of the shelf combos that tpi has everywhere.

please don't go down this road. there are arguments from all over the place of carb vs. batch port injection vs. tbi vs multi carb vs. sequential port injection vs. .......blah blah blah.
that is not what this board is about. we are here for tbi tech, not to determine who hs the best argument in a bench racing pissing contest.

Wow TBI's can't break into the 13's? Shane B.'s Vortec 350 Firebird: 13.5 with a slipping tranny.

That car you posted is very nice, dont get me wrong.

But he has $2000 in the short block, $1500 in the heads, $250 in the cam, $300 in the intake manifold, $200 in the runners, etc etc etc... Im sure there are carb guys and LT1 laughing at him for spending all that money on it and running 11.9. Hell there are 11 second n/a bolt on LS1s.

Every efi system has its advantages / disadvantages.

Wow, this wasn't very smooth.
TBI has it's strong points and it's disadvantages. One of the biggest disadvantages was that it came on only the low output v8's, it's strong point is the simplicity, adaptation to any engine easily, can use carb intakes, doesn't have a MAF and injectors don't come in packs of 8 costing over $300!!!
Oh yeah, and TBI has no problem running a single plane intake unlike carbs! Oh, did I mention it's simple, cheap and still gets great gas milage because of the accurate fuel control?
Don't get me started.
Anyways, does anybody have any info to tell me that my car would be faster with TPI or a carb? Nope...okay, so I guess TBI is doing it's job and doing it well.
TPI worked great on a small 305 but it just seemed to require too much work and money to get it to run the numbers a carb would put up after a few mods!
Chuck, let's not even get into comparing the generation small blocks, that'll take forever and get us nowhere. Of course the Lt1 is a better design and the LS1 is hardly a chevy small block anymore. With 18 degree heads and all the trick technology I'm not suprised by the numbers they make. Oh yeah, and I don't know any LS1 with just a few bolt ons that run 11 seconds in the 1/4. They get down to mid/low 12's with just bolt ons but it takes a stroker, cam, Nitrous, s/c to get em a 11 second time slip. Not saying it hasn't been done but it would most likely require ~500hp for a 11 second pass. Now if you're talking about dipping into the high 11's, that still requires more than 400hp!!!
But whatever, who cares about the LS1/LT1's, they aren't cheaper so forget em.

Well basically I want to see some results here!!!!!!! Show me some TBI cars with IMPRESSIVE times...... Im tired of all this BULL $HIT.......... His tranny was slipping !?!? WTF??? Show me the numbers.......... Find me a car that has as many mods as the site i listed and tell me what they run???

Keep in mind this is NA..........

Dude, don't look now, but no one here has to show you ****. You don't like it, beat feet. Plenty of guys are happy with what they have - so leave it alone.

S.

Well guys - I'm looking to dyno and race my car this summer *hopefully at least ONE of the two* so maybe i'll have some numbers. TBI can go as far as you can push it. I built up a 350 and did some research and am hoping to run low 13s *maybe high 12s* with some traction and 3.73s. The long-blocks TBI was put on sucked, not the TBI itself.

*hieroglyphics omitted for clarity*

TP

900 CFM ... With a good carb intake ... with matching heads, cam and exhaust ...

yeah i know or i should say did know a guy that had one of those, threw him 400 feet into the woods and his head swelled up like a basketball, hes dead..............ive been riding rice rockets for years and am no slouch, id never put my *** on one of those......just dont think 2 wheels is the place for all that power

b4 i quit drinking i was an olympic pisser ......:sillylol:

here's some numbers for ya:
camaroracer1992 ran 13.18 with a nitrous shot and an intake.
i ran 14.20 with a stock cam and chip with intakes/heads/ultimate/3.54 gears/mild convertor. and by the way, my tranny was slipping when i did that and it let go less than a month later.
jprevost ran a 13.8 at 101mph with a cheap crate motor and a holley tb. i can imagine he would have run a much better number had his unimpresssive tbi motor not spun the tires into teh middle of second gear
one guy here(sorry, i forget your handle right now)picked up 4mph with just a cam swap and free mods.
with the ultimate tbi mods and DIY afpr people are picking up 3-4mph

since you don't run tbi i don't really see why you care anyway. you clearly know little/nothing about it if you haven't paid ewnough attention to see the gains people are making with simple and inexpensive work.

Whats the matter? Slow night on the TPI board? I think I hear your mother calling, maybe you should go on home now. And by the way, I'm having fun modding my car.

soon to be installed. S/R torquers, zz4 cam, 1.5 full roller rockers

Where to start...hmm....how about the L98 with everything stock in good tune being able to pull a 13.8...yeah, with slicks and check out the following post.
https://www.thirdgen.org/techbb2/sho...8+full+exhaust
I'm definatly not working the potential out of this motor. I've got 65# injectors which are definatly not made for this motor!!! I'm lucky I got a 102mph in the 1/4 with such small injectors and a basically stock eprom and an exhaust leak.
I'm looking for some BBC injectors, preferably 90# but 80# is fine, if anybody has a source please let me know through e-mail.
Oh yeah, and this was in full street trim and full weight spinning the tires enough in 2nd gear that my car got croaked and a 2.1 60' is mostly because of my stock size tires and stock torque converter. I don't think my ET was very good but the mph is looking better and better.
As for fast TBI cars, like I said before, since nobody considers TBI to be for anything other than trucks it's very popular that people sell the car or don't do anything to it.
Give me some traction and some larger injectors and I'd have a hard time NOT getting low 13's.

edit: I'm 20 years old, full time student at OSU and poor...I think I'm doing pretty good all other things considered .

You're being a dumb **** (insert f or s word, don't matter).
The whole idea is the TBI DOES have all this potential but nobody uses it!!!
I won't get into a barking contest but have you noticed that I spent $3000 on my engine swap and I'm running a 102mph in the 1/4 with a LOT against me, oh yeah, and that was complete street prep, unknown fuel pressure with stock 350 eprom.
If I don't run a mid 13 with some more traction I'd be doing some wrong. As for the L98's runing in the 13's...ask them how much they've spent to get their car into the 13's and they won't just say exhaust!! !!
I also helps that they already came with nice gears and posi, heck, give me an L98 long block and I'll slap my TBI system on and run similar times/mph, don't believe me, give me the long block and I'll prove it. It's all about tuning and if you start taking about the aftermarket size start including "tuners for TBI" because I can think of about 6 companies off the top of my head that work with TPI (SLP, Arizona Speed..., Accel, Edelbrock, Liginfelter, and TPIS). You can't tell me that Holley is all for TBI because last time I checked they said they didn't have anything that supports more than 250hp and bolts right in .
You need to just stop asking stupid questions because as of right now no, nobody has spent the time with TBI to run it. You'll also find very few TBI guys at the track, it's usually TPI or carbs...

Prevost - chill bro - this summer you're going to see TBI times on street tires. If I run anywhere near 13s with street tires ImportsRsloths will need to bow down. TBI works fine

TP

In one week we'll see how my combo works out.

P.S. I have way more mods than whats in my sig

iroc22, you going to Mission this friday? It's supposed to be sunny.
