12 Second Club - 12.99 @120 (On G-tech)

How accurate have you guys seen the g-techs? On manuals? I have seen them be pretty accurate but the trap speed is usually about 4mph too high due to the track averaging the last like 100ft or whatever it is.

I ran a 12.8 @113 last time and soon as i left my clutch went out.
So from the g-tech it seems i might run 116 on a cool night like last night.
Heads and cam i have heard running 119-120 range.
Would 116 be alright for my mods or low?
Online hp calculators claim 116 nets 452 rwhp..they garbage?

Yea depending on your car weight. My trap speed nets me 430 but I am only at 405.

g tech's are fairly inaccurate. They base their information on you going on a perfectly flat and level ground, say, like a drag strip.

Just use the old fashion way and hit the strip, that will let you know real quick where your at! Good luck it sounds like you have a very hot ride!
