11:1 hi comp raptor
Guys it really depends on were you live..what sea level your at..i was running 11.5.1 in my rappy..Mine would not run right unless it had 95 in it..i would buy 5 gallons of 111 and mix it down with 91...to get 95 here is how you cut it..i gallon of 111 and 4 gallons of 91 makes 95...Like in my banshee i run 101 if its too cold for alky...so i go 2.5 gallons of 111 and 2.5 fallons of 91..thats makes 101..But im just giving you some ideals..im in oklahoma..so were at really diffent sea levels...

Here in Ohio, with practically an identical piston, I currently mix 105 octane with 93 or 94 octane 50/50. It runs great, and smells good too!
Seriously though, I was running a mixture of Cam2, which is about 112 octane, with 94. After diluting the mixture a little bit, I found it runs great now and it's not as expensive. You can run pump gas, but with the high-comp piston you will like the results you get with a little go-fast go-juice. Don't run straight high-octane race gas, though! It can lead to detonation. Four out of five high-comp raptors agree.

I run srtaight unleaded 104 in my 01 raptor (12:1 comp) and have had no problems. It says in the manual to run unleaded fuel only. I used to mix leaded 110 with 93 and didnt have a problem with that either, but after reading the manual I switched. You can buy race fuel by the 55 gal drum and its quite a lot cheaper. the same fuel I pay $6 a gal at a store is only $4.75 a gal when bought in bulk. Sunoco/Cam 2 is my fuel of choice, both are the same with different names.
