Dome size? cheetah cubs 68mm +4 stroke

[Ducman]

I asked this before but got no answer.

What size domes for cheetah cubs 68mm bore +4 stroke using pump fuel, 100 octane, and 110 octane

Lets assume +5 timming

 

I'm thinking

91 octane - 22cc

100 octane - 20cc

110 octane - 19cc

 

Does this sound about right?

You will need domes cut for the motor the regular domes you have listed will not work properly with the 68mm bore. I suggest you contact a builder and get them from them, or dlnoss can get you exacty what you need.

Yes, they will be BB domes.

Maybe I should just ask; What size domes do you run on your cub motor and what is the octane required?

 

Ask a builder you say? OK, calling all builders, I'm asking.

Ducman, its not just your cc's and timing you have to worry about, the squish clearance and squish band width must be matched to your cylinders at rated peak HP rpm in order for your squish velocity to fall into the right range. Re-cut off the shelf domes wont cut it...especially on hi-output designs on pump gas...Jim

 

heres some advice.

I didnt ask for a specific cc when I bought mine I told him what I wanted and he cut them for what I wanted, I run 110. Give Dan Wade a call or email him he is a great guy to deal with.
