Adam, is it fair to say that moderately aggressive cams would be needed?… I have mild JWT S2 and didn’t think I would benefit from the Cosworth plenum (until very high rmp)… _+ I don’t like the idea of losing low to mid trq either…

So, would 256 cams benefit from the Cosworth’s? (I have Crawford headers too)… I hadn’t considered this plenum for NA, but of course I’m not privy to as much research as you apparently have done.

 

I couldn't give an answer as I've got no experience with those.

 

In theory, and based on your flow bench tests… would a longer duration/higher lift be more advantageous than shorter duration/lower lift cams?

And what cams did you test with?

 

As I mentioned, rpm also plays a huge role, and the higher the engine revs, the better the Cosworth shines. I have no idea how that particular cam would interact. You would have to try it and let us know.

All tests have all been done via a flowbench and with a manometer.

 

I do like the BLING factor of the Cosworth, but I need some opinions. I'm built bottom end with Nismo cams, Vortech with additional bolt-on's to include the Crawford Plenum. Would I lose power with the Cosworth piece?

 

Instead of starting a new thread about this, i decided to revive this one since it was the closest thread I could find to get my answer...

I have a rev-up engine and I'm about to buy a Mrev2 + 5/16 combo and then I saw this amazing item... would I be looking at similar gains ( I could only find comparison of both on a regular DE engine not on a Rev-Up )

I will be going for a FI setup once the 2 and 1/2 years left of my warranty runs out that's why i'm really considering this Cosworth intake

Any input, tests, dyno sheets, experiences on a stock rev-up engine would be really appreciated guys
