I am thinking about hitting the drag one last time before getting exhaust, FMIC, and all that good stuff . So i was wondering if running 100 or 110 would be safe and if it would help out my time at all. Only performance mod i have is flash
current 13.7 1/4mile on 91oct

 

if you get another tune for the race gas it should give you some more power

 

Race gas make your car run helluva lot better and you will definately see some gains. The problem is that around here its $8/gallon.

 

EDDIE, stop trying to out-do me with the re-flash buddy, haha.
Just go to stage 2 already, since I don't think Im going to do any more performance things to my car lol.

 

haha i have to at least try
can't go stage 2 because i just broke my trucks windshield and have to replace it
i'm waiting for the summer time because i wont have college and i can just work work

 

yea true , my friend got 4 gallons of 110 for 34 bucks so thats like what 8.50

 

I hear its worth it to do once in a while to clean the car out a bit. It also smells pretty too haha

 

If you're just dragging, high octane (ie. above 93) is likely a waste. I doubt the car can respond that fast (if at all) so you'll make the same power but you'll be paying more for it. You want to use the lowest octane possible without getting detonation, a higher octane fuel is pissing money away and can actually harm a car (increased carbon deposits because the fuel isn't fully burned). For track days ie. lapping days, a higher octane fuel is a good idea since the car is repeatedly getting bagged for a long time.

 

Good to know. Thanks.

 

110 octane leaded race gas in a car properly tuned for non-leaded 91 octane will provide no performance gain and could even reduce the performance as leaded gas has a totally different burn rate and needs to be tuned accordingly.
