In the process of building my long time dreamed upon street/strip rig. 12v p7100, 14mm head & mains, girdle, cam, p&p head, runner intake, for my reg cab 1st gen. I had put together a compound kit for it back when it's original plan was purely a fun street truck, with a 62 over a 75. Now going a little more aggressive, put sticking with the 300/400, because it's the piping iv got at the moment. Been thinking a 64/80 or 82, or 66/88, or something in between, but that's not ironed out yet.
My questions about the external gates. I'd like to get an external Gate in my secondary to help lighting the large primary. I understand the concept of the wastegate, but not so much on the sizing of the gate. 35,40,50mm etc. Is there a formula to this? Are there differently types of gates, as in the physical engineering?
I hear guys running a variety of different sizes, and everyone says 'i haven't had any issues" I have got a gated steed speed, but would like to expand my knowledge, instead of "Eany, meany, miney, Moe" an external gate
