LOL no no not at all. I am being sincere. I would like to see your car running and doing 12's constantly and then tell me how to get it done.

If I hit my hp goal, with racing slicks, I sure hope I run faster than 12s

what is you hp goal, im aioming for 500 next spring, i hope ot be running 12's consistently this fall,

my oil pan is back on,

Blown 4-banger

I'm shootin for 500 at the crank.

Herndon_High_SS

jeez. 500 at the crank will turn out to be what around 390-420 wheel?

forgot the formula for it in FWD.

cool, yah i think 500 is an awesome goal, once my gt30r goes on ill start making more reputavle numbers

So what are you planning on doing with your transmissions?
I have seen the inside of our tranny's and the consensus is, they won't hold that power level.

KillerBee

True so does anyone know the specs on what our stock trannys will hold as far as hp wise i am thinking roughly 400 maybe a little more or little less

i guess ill find out than, i do have a beefed grand prix gtp tranny, from my 01 grand am gt i was gonna use, but that car was sent to the crusher


as for now ill worry about it when my tranny does grenade, maybe ill talk to shepherd 's trannies, the guys who make bullit proof dsm tranny's in fact im e-mailing them in regards to my tranny right now, ill definately have to supply a donor lol

Blown 4-banger

500 at the crank (factoring in a 17% drivetrain loss) is about 427 whp

Shift slow

No, since I'm getting everything sponsored, I don't see why I wouldn't be able to get a set of custom straight cut gears, with a longer first gear

Asphalt Assault

that is what Victory Red SS thought. then he found out it was cheaper to go with RWD LOL

actually just bump your HP down a little to make it an even 400hP the tranny can handle that. it is stronger than you might think. it will handle 400HP and there are axles that will go to 400 HP too. you should be safe and save yourself alot of bother messing with the F35 tranny. but what would be really cool is if it was possible to get a f25 in there. it is a six speed!

Rangerondubz

Your tranny will not handle that kind of power expecially w/ slicks!

Herndon_High_SS

I hate you.

thedubsack85

f25 is not the greatest idea.. i dont think it has LSD. and even if it does i doubt it would be the qualife main carrier like the comp pack lsj's.. which makes the stock tranny so much stronger...good luck with your build. cant wait to see results. break into 11's or jus plain break.. jus my .2cents..

Blown 4-banger

Uh, no thanks. I'd rather go through the hassle of messing with the tranny, rather than knocking my power back 100 HP

Glad to help!

Herndon_High_SS

Acutally I dont hate you. It's your sponsership that i hate. any more pics on the build? you know everyone loves pictures of the build process.

Cobalt_Supercharged

I don't know about the F25 specs, but the F40 trans is stonger than the F35 and is also a 6 speed. It is used on the turbo Saab.

The F40 is marginally stronger but not enough for 500hp and try buying a new one. The dealership wanted $13,000US. Buy used and who knows what you are getting.
I also found a company willing to make new parts for the F35, the input/output shafts really need to be replaced. The cost for doing that was as bad as a new F40.
There is also the option of doing a race-prepped auto tranny from GM, $25,000US
As SSnipes said, there is a reason I chose to convert to RWD.

shabodah

I know of F40 transmissions holding up in 450 horse applications for 6 months of daily driving abuse now. Just to toss that out there. And you can pick on up on ebay used for <$500 now, too. But the gearing is still far less than ideal.

guess ill look for a potiace g6 gtp totalled, as they come with on, ill need to do a bell housing swap if its possible, i can get a tranny on ebay like shab said for 500 bucks plus shipping

SwizzDSMSS

All you need to do is rebuild the synchros and bearings for a stronger application. I am pretty sure the input shaft is strong enough.

victory_red_SS

After that statement I am willing to go out on a very thin limb and say "you've never seen the input shaft"

Blown 4-banger

You'll have to forgive my friend. He's a little... slow
