I'm running a +4psi with a non-L engine.
I see 13psi once in a while.
The tune is fairly conservative, but I'm sure I'm not doing the engine any good with this much boost.

Still, the centrifugal guys are cranking out 12-15psi on non-L engines all day long without problem.

 

That might have something to do with the power not coming on so strong all i know is that when i test the waters in the Lightning forum they say go for it if you have the $$ for a built block WHEN it blows not if it blows. So i'll stay where i'm at if i see 400/500 rw then i'm happy and reliable!

 

Ya, Mike and I are working on a built block at this time as well. I hope to have it installed before this summer really gets underway.

I just need the stock block to hold out for another 2 months or so.

must be nice to work hand in hand with the man that leads the conversion.
