Turbo PSI/LBS/CFM Air flow

[RedDjinn]

Need HELP.. Looking at the K&N panel filter im going to run, the amount of air says 450cfm that it will flow free without force. 450 cfm calculates to 310hp BUT since the turbo is sucking and pressurising air does this till apply? Turbo is 45 lbs so 360hp. Couldn't find any calculations to help, I know air density will also play a small factor.

Yep you have to multiply that number by this:
(Boost pressure (lbs)/14.7)+1 that will give the new max flow

OK tried it came up with a number I don't think was right .....

cfm450 x 24psi / 14.7 = 734 Does that mean the flow is capable of 734hp?

[RedDjinn]

310hp x 24psi / 14.7 = 506?

1lb/min = 14.47 cfm

2871 flows 45 lb/min (according to garret website)
45 lb/min * 14.47 = 651cfm at max flow...

there is no way to work out g/s from lb/min...

Well I will just have to find out I guess lol. Cuz I buggered if I can work it out correctly, flow of filter to limit/chock for turbo :P

Just as well that,your filter will be locked in place by the air box or the mother might well be sucked into the turbo!!!!!!!!
GOD,that cfm puts a hole lot meaning to a blow job!!!!!! . Sound like you need to investigate a diff filter medium.
Good luck Luke.
