fair enough, yea the 7163 looks the goods, I wonder if it could make it to 380.... I think I will be moving up to a 7670 on my new engine as I want to turn it to 9500 and I think the 7064 will struggle to hold 28-30psi at that kind of rpm, even the 7670 might struggle, maybe an 8374 will be on the cards haha.
