ok. so now i'm at the time in my sig. and i wan't a 12 99
before i go for any tuning. do you think a good stall convertor and aluminum drive shaft will get me there? here is a list of my mods.

slp cold air, bbk twin 52tb, ported and siamesed plenum, as&m semi siamesed runners, tpis bigmouth manifold,
afpr@52psi, walbro in tank pump, stock injectors, heddman long tubes, true duals with h-pipe, electric waterpump, a/c smog delete, p/s delete, accell 300+ ignition, msd billit dizzy
& wires. ssm weld in sfc and liftbars.

 

I cant believe you dont already have a stall. From what I have seen on these boards thats just about one of the best mods for an L98 car.

 

i wan't to say the converter in it is from a vette but i'm not sure
it was explained to me only as a stock stall when i got it.
it is a 12 incher. what do vettes hit at? i hit around 2k of idle
but brake torqeing it only holds to like 1600 rpm before the tires wan't to break.

 

yeah i think vette stalls are 2000 rpms

sounds bout that from a 1600 brake hold

anyway , yeah a converter could help you hit 12.9x's lol

i cant believe how quick ur car is with those mods. makes me hopeful when i get HSR and a tune next summer

 

yeah i thought about changing intake design once then someone
let rip with tpi l98's can't run 12's on stock heads cam and bottem end. well you can see my results

 

mph is definately good with aftermarket TPI. with slicks and absolutely perfect launch i can see a high 12. aftermarket TPI with 1.6 rockers and a good tune will see 103-104mph or so. thats good for 12.9's for sure

 

Yes, a higher stall and an aluminum ds will help as long as you have good traction. I don't think it will get you 12s though.
What I don't see that can help is skinnies, disconnected or loosened front sway bar, roller rocker arms, underdrive pullies, disconnected alternator, tires (?), anything to lighten the front end of the car a bit, try an exhaust cutout, ice the intake...and a throttle body air foil, lol...

 

spend some money on a tranny
3500 stall, tranny brake, reverse manual valve body and shifter of your choice. that should bring your times down. and makes the car alot more fun to drive

 

sorry for not listing but most ask for engine mods.
trans is a full race 700r4 built buy tsi racing transmissions.
i do run skinnys and slicks current 60's are 1.82-1.84 9bolt rear
with girdle cover runnin 3.27 gears crossing line at 4700rpm.

chassi is ssm sfc,cross bar and weld in liftbars. spohn trackbar, lca's and no swaybars.
and i forgot the crank pulley
