Questions about stroker domes

[gregrob]

I think Shearers will run better on that porting and for what your doing. My in frame shearers ran a lot better than the oof cpi's

Depends on if you buy them new or used. I would just run in frames but that's up to you. You can find them used anywhere from 325-450 but they dont seem to be on here all the time. Just have to keep your eye out. New they're 650-700 I believe.

 

Another thing I thought about regarding your build is if you are buildin a drag bike, you should just get those domes from Kubitza and actually run methanol....

 

Here it's half the price of race gas so it equals out even though you use more, and the power is WELL worth it dude. I dont know if you've ever ran meth or not but it is the real deal. Not as difficult to setup and run as you might think either.

 

I have a FAST drag ported motor and I have ran it both on methanol and race gas and it is WAAAYYY down on power when runnin race gas. It definitely does the porting no justice because when it was on meth it was one bad mofo for a 4mil.

 

Just my thoughts , but when/if you do switch to meth you'll just wonder why you didn't do it from the beginning.

 

I would NOT run meth on those T-5's though, they won't let it turn the rpms and give it the flow it wants on meth. I've tried that.

David,

I didnt get the domes from the guy bcause he said they were made for alky.....all I bought from him were the Drag ported 4 mill cylinders from FAST, and a 4 mill longrod crank..... Im in need of some domes to run 115 octane and get me in the neighborhood of 170 psi....

 

edit: I could however ask kubitza and get him to tell me the numbers and ill get back to you....

 

Brad,

 

It really would be best to talk to Jeff. He would know best what domes would be best with his porting. I would need to know deck height (probably around 0.070" to 0.075"), and piston style (probably Banshee style). I would guess a 19cc or 20cc stroker dome would get you close to 170 but it's a guess without knowing the port specs or at least what size the other domes were and the compression they yielded.
