I put down 315 rwhp at 10 psi, but my engine also has 9.7:1 compression rotors.

reduced clearances do indeed make a huge flow difference on turbos like rad fans. those 99 turbos flow a lot more air than stock because of those abraded seals. if anyone disagrees tell them to remove their radiator fan shroud and see how little air they move then!
