Wow! T04E 50 trims rock!

After banging my head for a while and doing more math then I've done in some time, I'm forced to see the wisdom of what various others have been telling me about the 50 trim compressors. I've been hoping that I'll be able to realize my goal of 300 HP at the wheels with 20psi at the lest. Based on VE and PR calculations and laying this information over the top of a T04E 50 trim compressor map, I get some awesome results. Below is the point if I decide that I want to shift at 5500 rpm and 20 psi.

That's fantastic!

Now I really suspect my goal will be realized based on what others are doing out there with the same heads without porting and using the stock valve sizes. One freind of mine hit 320 at the wheels at 26psi with no mods to the head (as mentioned) other then an IPD turbo cam.

I state the above as comparison to what it is I'm running. The same 530 head, but ported, polished, grooved, and running 38mm exhaust (as opposed to 35mm) valves. The other difference is a V cam. That said, I should have superior flow potential through the head then he does, not to mention I'm using a far more efficient cold side then he (T04E 60 trim). This greater flow capability is the first reason I am hoping I won't need more then 20psi. But if that's the case, it's no big deal to turn it up a tad right?

OTOH, I could make an absolute boost ceiling of 20psi and just live with the results whatever they are. In this way, I can stay with OE pistons and ensure a bit less stress on the bottom end.

Yeah, I may just have to give that idea some serious consideration. :-)
