Ok so I'm going to the track for the first time with my new engine 13b cosmo pinned ported ra super seals s475 25 psi of boost so I want to keep my engine safe while I get up on it this weekend soo Im wondering what kind of gas should I put in it this weekend and what ratio premix while I'm at it? Thanks in advance for ur advise guys

 

Are you setup for e85?

What fuel was the car tuned with?

I usually mix 1oz per gallon, but that's because I don't have an OMP anymore.

Basically, we need to know more than what turbo you have.

 

the person who tuned your car should tell/have told you what kinda of gas to run, and what premix..

 

Sounds good on the premix I have no omp either n no Im not set up for e85

 

What do u guys to premix with?

 

C16 fuel

 

I use the Idemitsu premix, because it's made for rotary engines. But it seems the general consensus is that any good TCW-3 premix works just fine. There are several people on this board that get it from Walmart.

It also seems to be a consensus that you should stay away from the castor oil based premix because it gums up apex and side seals. But it does smell cool....

 

I use Motul 710 2T. ester based synthetic oil that withstands high temps, can be used in almost anything, injected and premix, JASO FD approved. It isn't THAT expensive compared to comparitive oils. I am finishing up some redline racing synthetic (little more expensive).
