10 mil cub dome ?

[JCSO605]

I have a 10 mil cub it has 20cc alky cut domes 175 psi. At about 500ft asl. I'm wanting to run it on race fuel 110 or higher???? Can I run race fuel with my current domes?

[JCSO605]

Oh and my timing set at + 10

will probably need more info in your domes squish , angle , band width etc

[JCSO605]

Oh ok. All I know is the domes were cut for alky

Might back the time down some...i got 17cc 190lb comp in a 4 mill on race gas and +7 time

[JCSO605]

Thanks quad god. Will I be ok running race fuel on these domes or should I buy new domes.

[quadgod211]

Well I don't know what the actual differences is in alky cut...so might wanna check

 

also run the best gas you can..

[JCSO605]

I don't either I don't know if it affects performance or harmful for the motor. I was hoping I could run the current domes on race fuel but I don't want to take any chances.

most likely you can run race gas with them. Wheres your squish at and band width. post up pics.

They are still installed. I bought this engine a while back from a hq member just getting around to completing the bike. It was built by d&m racing.
