Exhaust Port Dimensions 13b-REW- Turbo
I'm working on finishing my porting on my 13b-REW. I have a large pinneapple street port on the irons and am working on a shovel type exhaust port. I'm wondering about how large of a port I should go. Currently I'm sitting at a width of 52 mm wide with a total height of 30 mm. The lower end of the port is 20 mm from the normal exhaust port template/dowel line. Basically the top of the port is right around the where the start of the oe bevel was. I'm think I should add cut out another 5 mm to the bottom ledge so 15 mm up and total height of 35 mm. Any thoughts? Corner radi' are 10 mm.
