Just curious what kind of improvements people have seen. This & LCA's will likely be my next mods..

 

don't expect alot from it...it more of a system, and everything has to work together

with your listed mods...I would guess .05 to .10 off your 60'...maybe better, with the right tire

 

i bet thats true..but in the end with the more mods u add on... the better it will prolly benefit you....i plan on going to 3.73's or maybe even 4.10's once i get my 12 bolt

 

toby i am running almost the same mods on my 95 and was thinking about the same gear mod. what kind of quarter do you run now??

My gf with a 99 Trans Am went from 3.23s to 3.73s and nothing changed at all.

 

There was an article in an old GMHTP where they they had a normal intake/catback LT1 that they swapped a 2800 stall on and 3.42 gears and it knocked quite a bit off there times. I believe they said each one was around .25 or .3 in the quarter mile. I think there original gears were the 2.93 or whatever.
So...I would say you could look at a .15 or possibly a .2 if everything goes perfect.

 

Going from 3.23's to 3.89 gave me .26 in the quarter. My most dramatic et improvements were in the torque converter.

 

I don't have a baseline 1/4 yet I'll be hopefully hitting the track for a before and after of the gears later in the spring/summer. Track is kind of a drive and has horrible hours for those that work 9-5 mon-fri :/

 

And remember guys, hes talking quality torque converter, not some restalled piece of crap stocker. You don't what to look like this when you can look this .

 

i think there are plenty of rebuilt stockers that work just fine. is it because some of us dont pay for a name like vigilante that means it wont work as good?? maybe if i did the install my self than its also not as good as paying a shop to do it?? come on man. my rebuilt stocker worked exactly as advertised.

go 3:42's... i had 3:73's...
3:73 gears are weaker... thus the reason i broke them. and i didn't notice any difference with the 3:42's...

 

Z-Rated94 is absolutely right here. It really sucks but when it comes to torque converters, you get what you pay for and that's a fact. I wouldn't have believed it until I experienced it for myself.

 

I dropped .4 and gained 3.5mph.

 

with what...

did you have 2:73's?



cuz it looks like you took off .4 with this "Prior to the heads/cam/LT's/3.73's the car went 12.1 @ 116 w/an okay trans."

 

No... The car ran 13.6 consistant best of 13.5 on motor with 3.23's then a consistant 13.2 on motor with 3.73's.
