Running 12s in a Wbody?

Didn't sound like you slipped the clutch at all. That's as hard as you can launch with you setup?

I've practiced launching in my old Mitsu and could keep the tach at almost a perfect 3500RPM (powerband) through the entire launch with the street tires only making a slight scrubbing noise.

I believe you could drop your 60' a little more.

with that stage 3 clutch it's pretty hard to slip it... I've tried at the track and it never really worked out.

no kidding... thats cool. Havnt been on TGP forums in a while? Hows your Car doing?

hey guys for what its worth, my motor wanst ported, or had really anywork done to it (other then 1.6 rockers) when i hit the 13.6 @ 108.

Yes, traction is very limited...

you can kinda see how i gotta launch it in this vid: http://media.putfile.com/in-car-vid-60

why wheelie bars when you can just use spring rubbers in the rear?

Or Air shocks :P

Get some forged pistons and Crower rods and your preaty much there. Doesn't matter if its a 2.8 or a 3500. Boost the shit out of it.

You can mate a 4t65-e or hop up the 4t60-e.

Try some slicks or even some wheely bars out back to keep the front tires loaded. Traction is key.

well my stock bottom end got scattered across the highway.... so far im $100 into this with the block and crank and i still haven't sold my 3500 cam or timing cover


its not just about all out power though... its about usable power, with this i'll still be able to drive it everyday on pump gas and then go to the track and dial it up a lil bit... this should have killer torque too

try boosted and stroked 3500..... i think i might be able to make it there, if i can get the trans and axles to hold together as i said before

You dont need a 3500 or a stroker to get there with boost. Midnightriderz24 has gone 12.2's on a completely stock bottom end IIRC. Who has pushed the limits of one of these motors on boost? Ive yet to see or hear of anyone pushing 20lbs of boost on a 60*... Schweppe from GAGT is running 12.8s on 9lbs of boost. Pump that up to 20lbs and I dont see why he couldnt hit 11s. As it has been said many times, and you have noted as well, on the N body platform the transmission is the weakest link.

yeah, i know... but honestly they're not that far away weight wise stock... but mines not stock

I dont remember you talking about boosting or nitrous at all, and I highly doubt you will get anywhere close if you stay N/A. If you had a full on race car with some extreme weight reduction done, high compression and a monster of a cam, I think 12s could be had. Realisticly, and reliably, its not going to happen without a power adder though.

im looking for 12's after my 3500 build, that is if i can get the trans and axles to hold...

Your car isnt a w-body though

Anyone have any imput on torque converter stall speed for a 4t60/3400 topend with t04b/t25 hybrid? If i get a higher stall speed is there any way it would help line pressure for stock TGP trans? I think stock is 1835? Thanks
