99 SVT Lightning

I recently put my L under a professional tune, new pulleys (13psi), 90mm throttle body, bassani headers, and some other goodies.

444rwhp at 5k rpm and 545 tq.

I ran a 14.3 bone stock. With over 100 additional hp now could I be looking at high 12s?

Becareful they do not last long at this power level. Good news you can fix it with a lsx motor! 13.4 or 13.5 you should running close to a stock ls1

Id say mid 12's at least if the power is honest, and it hooks.

I have a lightning with similar mods. Its slow as **** which is why its a parts getter. You can expect mid 13's.

if i had to make a pure guess...........13.3 ....but more than likely youll have traction issues.

My guess is low 13s. Good air and good traction this fall and you should be able to see a 12.99
