Hey guys. Im about to dyno my car tomorrow with the new setup. For the experienced guys here.........where is the point in which u need race gas??
At what power level should i run race gas? 93 octane is readily available but sunoco stop selling 94 octane recently.
I heard race gas ***** up ur sensors and clogs ur fuel filther. I dont have a cat so i could care less about the issues with that.
I need some facts and opinions guys!
Thanx.

 

the higher the octane the less chance of having detonation, on c16 u can run alot more timing to make more power, but u cant have alot of timing on 93, anythin over 450whp u should use c16, i've seen over 500whp on pump gas but its not safe,

 

and my car is tunned on crome, running open loop which eliminates the o2 sensors,

 

Thanx a lot. Ill be on te dyno today and ill let u guys know how it went.

 

no, ledded race gas fouls your 02 sensor. but you get use unledded race gas (I think they make up to 109 octane) and no fouling.

 

Leaded gas will shorten your O2 sensor life but I would rather buy O2 sensors then A motor..

 

if you're going to drive aroudn on 93 octane. tune with 93 octain. reserve racegas for well .. a race tune because most gases out there ned a lot of additives to increase the octane. These additives dont combust as easy as lower octanes so they require more timing in order to work correctly.


so if you tune on 93 octane. an dget 115 octane at the track youll lose power cuz you dont have enough timing to fire it off.
