LB9 vs Tiburon vs 4th Gen Camaro - Third Generation F-Body Message Boards

HCR13 · 04-25-2009, 03:43 PM

I figured I'd post this funny story since for the past few months all I read is about TBI and V6 thirdgens trying to race, never anything about TPIs. Yesterday, on my way to work, I accidentally raced a Tiburon and a 4thgen, more than likely a v6 or a bad running LT1. My car is having serious issues when idling. It stumbles and wants to die when at a stop. The only way to stop this from happening is to give it a little gas (keeping the rpm's about 1k). I pull up to a light and there was a Tiburon on the left lane and on the other side of him was a black LTstyle 4th gen Camaro vert. I didn't think much of it, I normally don't egg people on. Like usual, my car started doing the usal idle shake, so I put it in neutral (auto trans) and started reeving to keep the rpms high...well, the Tiburon thought I was reving at him so he started reving too and then the Camaro started reving too, I guess he thought the Tiburon was reving at him....so I figured, what the heck. I looked in my rearview for a quick cop check. I had the car at around 1.5k rpms. The light turn green, I put in gear and mashed the gas pedal. Well me and the Camaro just leaped and it was as if the Tiburon was standing still. He was gone, so it was just me and the Camaro at wot. It had a deep sound, but not the deep V8 sound. It could possibly be a v6 with exhaust or possibly a v8 with stock exhaust. I've heard LT1's and they have a distinct sound of their own... I'm not sure. he was a bit ahead of me, maybe a fender and then slowly, I reeled him in and passed him which I was surprised...he was still racing by the sound of the WOT. I got to about 75-80 and he was behind me a car length or two. We were aproching a light and my turn off so I slowed down and into the turning lane. As he kept going I just gave him a peace sign out the window... I thought that was pretty funny that I unintentionally egged 2 cars on. I'm actually delightfully surprised that my car did so well for an 87 LB9. Mods in the signature...

btw, no NOS was used...

Nice Kills. You probably raced a V6 Camaro. If I remember correctly they ran 15's... Sounds like a lot of fun though!

HCR13 · 04-25-2009, 06:21 PM

another thing I've noticed about my car recently is that its pulling alot harder on the top end, I know TPI flows badly on the upper rpms, but recently, its been doing better on the top than it ever has...

ThePain · 04-25-2009, 06:44 PM

Lol, that's pretty cool. Never had a race with more than one car at once... lucky!

Way to go man, good kills!

Stock TPI setups have been in the low nines, at 150-mph. The setup itself isn't bad at all, it's mainly the throttle body, as well as an ancient processor (ECM), being the only real restriction....

I have news that same throttle body is used on the Ramjet 502 making over 500 HP. It couldn't be that bad.. The real restriction is the lower manifold and the runners.

im sorry but

stock?

are you taking n/a? forced induction its possible i guess... id love for you to prove me wrong, maybe you confused some numbers?

Well, I meant if there was in fact a restriction out of the entire setup, it would be the stock throttle body itself. Also depends on how much power your looking to make. The stock TB, hell, the stock MAF is capable of very good numbers, when the prehistoric processor doesn't get in the way of course....

Umm, what do I get if I prove you wrong? A new set of injectors, maybe....?

As for forced induction, you completely missed the point. If a turbo is able to push x amount of air into the combustion chambers to put down the numbers, then the runners are obviously not a restriction, at all. They only become a restriction when your running too much displacement. I would draw the limit at 355 cubic inches. As for proof, no need for the bullshite flag, just ask me next time, and if I can't provide the proof, then the flag goes up....

Ive raced a tib se gt with the v6 when i had my z beat him by like 4 or 5 lengths and was still pulling when i let off. Everytime i raced him it was worse an worse lol. Ive driven the car its not slow but its not fast. everytime id let off hed do the r i c e r fly by tho it was funny. never raced a 4th gen tho wanted to

rojas1826 · 04-27-2009, 05:22 PM

yeah thats great news an lb9 kicking butt mine couldnt even catch up to my friends z28 lt1 or most of the slightly tweaked hondas but mine is the 86 with the really lame cam makes about 190 hp i think can never find 1/4 times for stock 86 though so i would guess 17 sec im hoping the engine dies soon so i have an excuse to drop a 350 until then im the slowest camaro on the road haha j/k it does nice powerslides though

HCR13 · 04-28-2009, 01:10 AM

yeah, my car has come along way since when I first got it. I test drove a Camaro with a bone stock L98 not too long ago and remember thinking to myself, "man this car feels slower and sluggish than my TA"...then again, I have full bolt ons... It feels nice to know your "piece of crap" turdgen can take on newer cars...really boosts your car-esteem...

Need to post that in the thread "why do you love tpi."Guys over there bashing tpi.Now I know its not the best setup for race but it can be made to move.

I never can get these links to work when I post them.Dont know what I`m doing wrong

HCR13 · 05-04-2009, 01:22 AM

Yeah, I don't see why people like to bash TPI either... I see how its not the best race-oriented intake, but its not useless as people seem to make it...I think its perfect for forced induction and to be honest, its one of the most unique engine intakes out there... most other intakes are really bland/flat and not much to look at... I remember when I first got my T/A about 3 or 4 yrs ago, (I wasn't into cars back then), I saw the engine and thought...WTF is that? All it needs is some plutonium and a flux capacitor and it belongs in a DeLorean with dock Brown and Marty....
