hey guys,

Bulit a 500HP+ tpi engine, need a recomdation on how to get the air in for it. Its getting and EZ EFI treatment as we speak so no more MAF (yes!!) As of now I have a RC 5000, which from what I read only flows 600cfm(hot air), or a modified tpi box that built thru instuctions on the boards but KN tpi filters from what understand only flows 550-600cfm cold. so the filter would not support the mod box? from reading I need 1000-1100cfm to support the HP. What cfm should I have ? and how do I route it? Need some help!!

Thanks

 

Very optimistic on a 383 with TPI What did it dyno at ?

As you can see from the intake comparison linked above ,the intake is the limiting factor to making power
Change the intake to something that breathes

 

Sorry, 388 HSR, Pocket ported and port matched iron eagle 2.02 1.60, 58mm tb, lunati vodoo , 36lbs inj

 

So it is no longer TPI

Engine is just a pump ; can only move X amount of air @ Y revs

All the CFM calculators are showing a 383 flowing around 775cfm @7000 rpm ( assumes 100% VE )

I got ya....did all the calulations, so what are some options? as of now im only getting 600cfm right? looks like I need to be 700 to 800 cfm and hopefully cold?
