what type of fuel should i be running?? 93 or race fuel??

 

93 race gas is expensive i have 12:1 comp and i run pump gas

 

Pump premium is all you need for 11:1.

 

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...

 

well i live in michigan but im not sure the sea level

 

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.

 

thanks alot ill give it a try and i let you know!!!!!!!!!!!!!!!!!!!!!!!!!111111

 

Race gas prevents detonation; not cause it.

 

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.

 

Anything more than pump premium (93-94 octane in MI) is a waste of money if you're running a true 11:1 piston.
