Any bench flows of Rb25?

[BlockHead]

Does anyone know how much an RB25det with Greddy intake flows. I am trying to pick a turbo and I was just curious to how much the head could flow.

bump, does no one have any numbers??? I was wondering because I wanted to match a turbo up to the engine and I need to know flow rates to see where I am on the compressor maps

By all means have a lovely time with the calculator compressor flow maps and reams of paper . If you do some searches here under Hi-Flow turbos you should get a feel for what the guys are using .

295 cfm at 9mm lift, the Greddy manifold makes NO difference. ie; at that flow level the standard manifold and throttle body are more than "big" enough.

Hope that helps

What flows 295cfm @ 9mm lift? At what pressure?

At a wild guess I'd say he's talking about the topic of the thread and lift of the cams :headspin:
