Getting ready to run my new combo which is a 9:1 compression 518 BBC with CnC 365cfm BB2xtra heads and solid roller cam with 729lift. Running on E85 and looking to spin the motor to 7000rpms to achieve a 15lb to 20lb boost range . CSU dual. needle and seat carb and shooting for around 1500hp at the motor.
I'm sure a few of you are running a similar set up and wanting to see what boost numbers you guys are seeing?
Blower pulley is a 48 and crank pulley is a 66. with a 5.4 step up ratio those pulley put me a 52,000 blower RPM's at 7,000 Engine RPM's
I know a few other variables can change the boost but with the given size engine, blower speed, heads etc
Let me know if you need anymore info. Unfortunately I don't know the cam lobe seperation
