My build is
B18B ls head nonvtec
GT35R
75wet shot

Ok so i dyno @600whp pretty close lol. i Want to make The car a pretty consistant
10sec car. I have some doubt in my pick of trans. I have a stock LS trans 4.2 fd with
Mfactory lsd. Ill be shift @8500rpm according to a gear caculator ill be falling back to far in between shift and im think il have a lot of power loss and a lot of rpm to make up that said i think the trans is to mush gearing for my setup. i dont want to get rid of it but if anyone has any better suggestions or if you think il be fine let me know.

I also have 22x8x15 MT's i know there are undersized my old car only made 250whp. so what size slick well work good with this trans and setup.

24.5x9x13 mickey thompson's and a gsr trans and go have a blast. The tire you have as you know is small and the gearings is too long.

Or you could try a B16 tranny and take the lsd from you LS and put it in B16 tranny. Ans get a bigger tire for sure like Miller said!!!! Good luck

25" M&H will work perfect for that set up

im also running a non-vtec head, when i was at 600hp(25psi on a s372) with a ls tranny shifting at 10500,my rpm dropped to 6900. with a gsr tranny now, i drop to 7300 between shifts. Gsr tranny is a huge differences

i have had all three trannies in our car and the one that works the best is the gsr gear set. the b16 was to short and the ls was to long. and it was all on a set of 24.5 X 9 X 13 MT slicks.

so you guys are agreeing that the ls is to much gearing for the setup, my consern on a gsr tran is if im only shifting @8500 not @10000 like most guys well it be capable of traping at least 140mph? well 26x8.7x15 MH be to much tire or work out

why not take it to 9500 or 10k?

get a real head/cams.

The LSD will work in a GSR tranny u just have to use the ls/b16 bearings.

I like the idea of keeping my ls head for now. not to many guys out there making 600+whp going 10s and 9s with a nonvtec setup. Anymore tire size suggestions anyone on a 15x8'' wheel?

I really like my 25x8.7x13 set up. Id say go as big as you can you wont regret it.

sorry but cant compare m&h to MT's sorry.

dominidg123

From what i heard from others, MT's grip better then MH i only ever used MT. but i havent heard any terrible feedback about MH.

MindLess311

I get consistent low 1.6s out of my m&h 25x8.7x13 on my street car. But at the same time they are the only slicks that i have run. Just saying they work well for me, im sure every car and track will like something different.

dominidg123

Mindless311 your pulling 10.6s out of 417whp with 25x8.7.13 if so your def hooking up good.

MindLess311

Thanks man I was prob just north of 450 on that run but have only been dynoed at 417whp.
