So Ive been systematically upgrading my car, hitting the track with each mod/shaving time down, I was hoping to hit an 11.99 this year. I did a 12.78@110, that is the first log, 22 psi since thats all the stock WG spring allowed. I upgraded the WG spring, upped the boost to 26, and surprisingly didnt pick up ANY trap speed, ran a 12.61@110, which was pretty much only due to 60 ft. So question is WHY? I didnt drop timing, knock, IAT stayed nice and cool. I see people with a stock 6 bolt running in the 10s with mid 30s psi, so whats holding me back? I do show more lbs/min, but being on SD I imagine its just a calculation and not measured. Relevant mods are-
Cyclone intake (it is actuating right)
BC 264/272
ported 2g ex mani
TL TD05 20g
VRSF, water/meth
The longblock is stock and has some unknown miles. Stock head, valves, TB, ect. It did pop out the dipstick on this pass if thats a clue, but I leakdown tested it and they were all in the 20%s, which is where youd expect it I guess. So what should my next mods be? Thanks for looking
