Thread: CNC Combustion Chamber for Turbo 90mm Bore VEs!

Does the same cnc program work for de(t)'s i.e are the ve combustion chambers the same as de(t) ones. The reason i ask is a machinist mate of mine is doing a program for a silvia sr20det and i was wondering if the same program would do my ve head

Cheers

the combustion chambers are a little diff, they are smaller. that is why the comp ratio with a ve head will be about .8 higher cr

Right that makes sense. Guess i'll just have to pay and get it done properly.
Damn I was so hoping to get a freebie

Wow that guy has a really really steady hand!

The new combustion chamber cc's out to 48cc. This was tested on our race head that has custom deep dished valves, so it may be 1-2 cc's less with regular VE valves.

How many cc's with the untouched combustion chamber? I see that by doing this you can gain back compression with custom pistons. I know there has been talk about "pinch" needing to be there for better burn but thinking about it you can compensate it with a good pist design. Also you have pushed these motors to 4 digits already with this kind of CC so it is proven to make power efficiently....what were the EGTs though at high boost?
