I can believe it. For someone who may be new to turbo cars or high performance cars. With regular cars they always tell you to run the lowest octane possibe, and that anything higher is a waste. In your mom's Buick you won't see any difference between 87 octane and 100 octane.

In your EVO, however, you will see a fairly noticeable difference. . . How and why this happens I will let the OP research on his own time, as it's been discussed previously in many threads.

^ On a stock turbo EVO you probably cant use more than 100 octane. Running straight C16 is practically a waste.

 

Do you mean on the stock tune? I agree on the stock tune that once you start moving much past 94 octane, maybe up to 100 octane that the ECU just isn't going to give it any more timing after a certain point. C16 would be a waste.

A tuned stock turbo EVO will have the potential to make more power (under the curve) with C16 than with 100 octane. More boost, more timing before getting knock. You may be able to run 30psi spikes on a stock 9 turbo on 100 octane, but not at the same timing levels as on C16. . .

So i went to the gas station yesterday to check out the turbo blue, its leaded 115 straight from the pump
Jeff Jeske, you said you used it, is this the same stuff you used?
I started another thread on turbo blue, so check it out and put down watever information you know about it

You may be able to run more timing but I'll bet you aren't making any more power. Back in my DSM days I compared street blaze 103 to C16. C16 required more timing but didn't make any more power and this was using a FPB28 turbo basically the same as the EVO8 turbo. I wont argue about it because most people aren't going to pay for C16 and if they do only the hard core MF's will get tuned for it. I'd say less then 5% run it.

Here is another race fuel link to review..... good info ....

Interesting. I was wondering if it would be better to get a race gas tune for C-16 or the highest unleaded oxygenated race gas. I'm just going to use the unleaded race gas.

 

That's fine. Let everyone believe 100 octane will make as much power as C16 on a stock style turbo. Better for me when I pull up to the staging lights!!

BTW, in the past 2 summers I've run ~160 gallons of C-16 through my stockish turbo'd car. . . and it loved every bit of it

 

with my mods in my sig...
how much boost i can run with 110 octane?
also with 112 octane? with no tune?

 

^^?

 

With stock timing.... you can run the max boost the stock turbo will provide.

 

how much psi are we talking?

 

I run on C-16 all day.

 

Im still a fan of AV-gas.

you can afford to run it all the time.

 

25 psi, 12:1 AFR, and stock timing easy.

 

is 24 psi be ok for straight 110 octane?
