its orange not yellow!!
The part about the race fuel in a naturally aspirated low compression motor tells all...
That says that you have very little experiance in drag racing...
If you have been around the game a while you should know that 87 octane makes more power but burns so much hotter that it causes detonation.
That being said you ALWAYS run the lowest octane fuel you can to make the most power with out causing detonation..
260 RWHP is enough to run 12.90's with at least a 1.7-1.8 60 foot and excellent driving...Notice EXCELLENT driving...that comes from seat time..
I've run 12.90s in a stock 91 mustang LX that made 230 RWHP running 3.55 gears but it was with a 1.6 60 ft and at 102mph.
Then more comparable I ran a 12.90 in my 97 Cobra with 271 RWHP, 3.73s, and a 1.8 60 ft..
Every .1 in the 60ft is worth .2 at the top end.... if you want low ETs then its all at the starting line...
what color s197 do you drive?
