Is it a good idea to premix with C16 or does it have enough lubricant in it already? Also, any know how much premixing would drop the octane rating?

premix!

Yes premix, and you need a significant amount to lower the octane.

I'd like to know this as well. Possibly from someone who makes big power with c16/rotary. Aspec, you guys haven't put out any 500whp+ 7's have you? C16 seems pretty lubricated by itself and would be sufficient enough for drag racing.

why take that chance.. just use premix.

I'm not going to do something that's not necessary.

No we only put out 300hp ones. We still haven't learned how to use our dyno unfortunately maybe someday though!!!!

I have been only using c16 fuel and i premix it still. As for power, i havent been on the dyno yet, but I am running around 24- 28 psi on my t78 turbo.

I use premix and c-16. 22-26 psi

How much of 2 stroke oil its necessary for a full stock FD fuel tank with c-16 ?

What's a good premix ratio for high hp rotaries that don't have a omp?

crispeed

For your application 6 to 8 oz to every 5 gallons of fuel.
C-16 has a very high lead content which is very corrosive. I seen people experience stuck apex seals after using c-16 and letting the motor sit for sometime. Your spark plugs also suffer a lot not to mention anything that exhaust flows through. They get completly rusted out. Just check out the turbine wheel after it sits for sometime after using c-16.
My choice for pre-mixing would be some type of castor based oil. I normaly use RC-3 racing castor from VP fuels or Klotz BeNol racing castor oil.

that just seems like alot of oil to add to gas......... you'd think that it would bring the octane down but I'll try it. I just put 15 gallons of VP C16 in my car today, so you're saying I need to add 18OZ of oil?

Thanks dude....

i've always added slightly more than one oz per gallon.

crispeed

It depends on your application. Omp, rpm, power etc. just to name a few.

what about if your still running the oil metering pump? should you still premix for extra precaution??

i would, maybe 7-8 oz per tank
