64,680 rpm is what I am coming up with, that the F-1R will be spinning at 7000 rpm. The F-1R has a 68,000 max rpm rating. With your combination and probably close to sea level, you may be around 24 psi. This is way to much boost for a four bolt head and block combination. Bob

thank you bob I know the f1r max rpm 68000 .... But I began 6500 rpm to 7000
I did not want to go to 7000 rpm But I went to this limit, forcing ,, Because the amount of pressure not exceeding 13 psi
no boost leak
no air filter

You're welcome. With your combination you'll find 13 psi pretty early in the rpm's. Bob
