Turbo question ..... it's going on my EFI engine =-)

Hi Mike

Yep both of them.... am I blind, is the info in there?

I can work out airflow at redline rpm using one of the formulas from 
Corkys book but how do I work out at what rpm PR is reached. 

>What kinda engine

Ford pinto 2L also known as the 2L EAO engine with big valves 
cc'ed and modified chambers, ported, double valve springs and 
cosworth pistons. Everything is getting balanced at the local airport 
machine shop so I'm hoping for a redline of 7000 rpm. I want to run 
15 to 18 psi of boost. The IHI I had was a bit small for what I want. 
At the moment the best looking maps are for the T3 60, T3 super 
60, T3/T04 hybrid or may be the T04E 46.
Assuming that 140cfm = 100hp 18psi of boost at redline should 
give me about 290hp. If I do get this power out of my engine it 
should propel my 2333lb ' 72 Ford Capri along nicely.

> ya got? 

It's an old analog setup. it's completely adjustable but it is basic 
and it's designed to work with boost so no problems there.

Cheers
