Tbi Vs. Tpi

[crapmaster4000]

I see there is a urge to discuss the different engines from camaros. What do you guys think? I know people who swear by both and I have a buddy that put tbi from a camaro in his truck and it runs great. But whats everyone elses opinion?

Ohh I see, so this thread isn't for me right?? LOL

[crapmaster4000]

well what do you think?

small world huh

Sure is, that looks to me like throttle body injection. I hear that gets off the in faster than a tuned port.

lots of variables that come into play there, not just the fact it's tbi

bah....

both have their purposes pro's and con's nuff said on my part...

What advantage does TBI have other than being more simple? I have always wondered why GM never installed the TPI on trucks since it makes so much more torque than TBI. I have thought about converting my 87 TBI Suburban to TPI but I don't know if it's worth the hassle.

[Twin89s]

Its cheapier than TPI for one.
uummm..... well crap ok 1992RS can join in on the TBI pro's I am not a fan of them but he seems to know some stuff.

TPI is sweet but on a 350 it falls on its face at 5200rpms. So if you were to go TPI I would pick up a holler stealth Ram intake manifold. If its on a 350 it will really breath!!!

while we are on the subject , hopfully ill get my 350 longblock to rebuild and im wondering if i should stay with a carb setup or go to TPI , i have never owned a TPI car what are some pro and cons? whats YOUR oppinions?

tbi isn't really any more simple than tpi. only difference-8 injectors instead of 2, and the location, that and all tbi uses speed density instead of maf. which 90 and up tp is speed density too. while some would argue that the injectors being closer to the valves creates more power i think it's just quicker throttle response, but i think the what really sets them apart power wise is the tuned runners.

tbi sucks i should know i like to smack them with hammers.
tpi sucks alittle less. it's all a verying scale of suckiness. carbs dont suck but your injection sucks.
and that motor right up there looks like a stock piece of shit. wow i have yellow gay accel wires look at me wow. and cheapy headers whoooo im impressed and look i painted it chevy orange wowsers. and look at the pretty painted manifold i should be in the low 15's now. like me like me!

wtf is ur problem?

[4onFloor]

oh ya, and if you had any brains at all you'd notice that it's got LO9 valve covers, but yet the dipstick is on the drivers side. kinda tells ya one thing...the heads arent original nor is the block. just cause there painted orange doesn't mean there stock heads
