If you follow the rule that every tenth you can take off your 60' is worth 2 tenths in the et, then with a 2.0 to 2.1 60' you would be in the low to mid 14 range. Look like a pretty healthy sho. Sticky tires would help alot. How were you launching? What was your trap speed on the 15.4 run....higher or lower?

well the front tires were dropped to about 20lbs. 235/45/17 with 2 degrees of camber all around. the 15.1 run i launched at 4300 rpms. clutch dump, held the gas at about 3/4 throttle tell the tires hooked. i shifted at the rev limiter. watched and heard it bounce one and grabbed the next one. the other runs i didnt watch my rpms. just went off out sound like a street run. and my clutch slips slightly in 6-7 rpm range. rpms keep climbing but mph falls off. only through first and 2nd though. the 15.4 run my mph was 93 i think. didnt get to keep that slip. yes tires would help.

I'm going to go ahead and assume he will be running your average performance street tire later on. With a stock Diff/Subframed SHO's, a 2.2 is about the best your going to get on that kind of tire. Based on his trap speeds, his car would have no problems running a 14.6-14.7.

My 95, with a 2.25 60' time, would go 14.7@95 , on more then one occasion.

One thing, dropping a street tire to 20 PSI is absolutely useless. The lowest I go is 30-32. You probably lessened the contact patch significantly by running the tire at that low of a PSI.

Sounds like a healthy SHO.
