Squish Clearance help

[BansheeShredder]

Hey everyone! Been lurking the forums for a while, just never made an account. 

 

Anyways, I have a 2006 shee that I'm turning into a 4mm stroker.  I reused my old domes and chucked them up on the lathe and cut them to fit the new pistons. Im sitting at .047 Squish clearance right now, I'm wanting to run 91 octane, around 150 psi. I'm thinking my squish needs to be more like .055-.060 to achieve those psi numbers?  Motor is not broke in yet, but the current cranking compression is 230 psi lol.

Just buy pre made domes.

This. Call noss, redline, or fast and tell them what you want.

So you cut them for a 4 mil but the cumbustion area got much smaller because you left it alone?

You need to cc the dome you have now . What series piston did u use

[BansheeShredder]

Yap, that's the next step is to cc the domes. Not sure how much to take out, think they need to be 23cc. Running wiseco 795.

I'll probably just order a set. Talking to f.a.s.t. now.

Domes are something a few people understand. How different angles and widths effect power.

Fewer probably willing to share. I know nothing about domes.

Just to call a builder and say I have xyz parts with ABC port timings. They say okay, ask a few questions. And that's it.

Ya, that's what I'm going to do. I don't know much about domes either, also don't want to damage this motor, was just trying to save a dollar haha.

You already are saving a dollar by calling fast in the long run,do you have equipment to rechamber the dome, , normally existing domes don't wor out well blanks are needed
