that turned out nice! The hardest part was answering all the questions from the guys at the machine shop. https://www.nopistons.com/forums/pub...1047683785.gif |
hey the ports look good did you port the exhaust ports ur self? i was told not to take the porting downwards because it can create too much overlap?.
but looking very nice. |
If you port up on th exhaust ports it creats overlap.
The downside to porting down is that it shortens the power stroke, but it allows you to get the affects of porting the exhaust w/o overlap and hurting bottom end. If you port down on the primary intake ports it creates more overlap. On turbo motors (street driven) I try to stay away from this and port more up. On N/A I like porting down on the primaries. It takes away from the lower end but it really wakes the car up on in the upper rmps. Hope that helps. |
