Here in New Orleans we now have a race track that sells three grades of race fuel with a high price tag. Anyways just thought I would ask if anyone just ran race fuel in there car as a daily driver and would I really see a difference form the 93 contain I'm running now, maybe put just a few gallons in there.

 

I think the race fuel is more for high compression engines. I don't think you would notice a difference.

 

The simple answer is not without a tune.

 

The wisest answer is: you don't use race fuel to drive around town.

 

You are correct I was just asking if there was any performance gain by adding some race fuel to the mixture ?

 

Only difference you'll see if your money running out with no gain.

 

This.

 

Agree^^^

Also might want to make sure it isn't leaded Race fuel as it can do more harm then good.

 

Isn't race fuel non oxygenated?

 

You're not going to see any gains in high octane race fuel without a tune. I take my car to the track all the time and just for kicks I ran some race fuel (100 octane gas) in my car to test it out. It did nothing to improve my ET's at the track. So I have verifiable proof that unless you have a tune, you'll see zero benefit in running high octane gas beyond 93.

 

Thanks it was just a thought as I was pumping 93 at the pumps that were at the track.

 

C16 smells AWESOME, but at the price of a drum of fuel on a DD car its pointless. That car isn't making that kind of power. I have seen 8 second passes on 93 pump.

 

You'll lose power. The higher the octane, the harder it is to burn, and the more cylinder pressure it can withstand before pre-ignition. 87 octane burns faster than 116 leaded race fuel.

I ran 108 in my jetboat only because it was a 13.5:1 BBC and I had to. The smell is nice too though, just not for $11 a gallon locally.

 

No point unless you have a bunch of mods and a tune.

 

Go with E85 over C16 anyway....just make sure you find a place that cycles the fuel and it dosen't just sit.

E85 and a tune...

And you don't need "a bunch of mods" a bolt on car TUNED for that fuel will see a gain.
