how much c16 to be safe ?

[tommy s]

lets say I'm pushing over 700whp at 18# of boost , how many gallons of c16 woud I need to add to lets say 1/4 tank of 91 octane when I hit the track ??

If you're not tuned for it yet, I'd look more into Shell URT-Advance.

110 octane, unleaded. A lot better for an EFI car, since it won't kill o2's, plugs etc like leaded gas has been known to do.

Well I live in retarded gas land Canada wich 91 octane is the best we have
believe me if we had 110 octane I'd be a happy man !!

Do not run C16, it's leaded.

I runs a 50/50 mix and have no problems. Keep an eye on your front o2's. If you get a Code run some 93 and it will clean them off in most cases. Imo "Better to be safe "and have to replace o2's than a short block. Most engine failures are from detonation and shifts over 6300.

For the same $ you can run Shell URT Advanced and it's unleaded, not oxygenated. No worries about O2's or cats.

At 18 pounds of boost, I have a 93 tune and a 104 tune. Your street and race tunes should be written to a specific octane which you should meet or exceed. A 50/50 mix of C-16 and 91 should get you to 102. You can blend URT Advanced like C16 based on stoich. Go URT if you still have cats.

Look into some Torco for race days. Relatively cheap insurance, easily available and convenient.

I run straight C-16 only prob is that the O2's dont like it

But yes Torco will work great

 

[tommy s]

I run torco when I turn the wicked on but taught c16 would be safer ??maybe not?

 

[stkjock]

What ever fuel u chose, whatever blend, get the car tuned for that combo!

 

[GT500RedStripe]

Torco will not give you more than the equivalent of 7 octane points. So if you mix with 91, that gives you 98. What does your race tune call for?
