pk,
I know its a big goal, but without goals what would we have to shoot for. Trust me, the turbo isn't the only thing thats getting work. I'm just trying to get some ideal of where people are with what turbo and mods.
I don't think 400rwhp on pump gas and stock bottom end us un-attanable. Its a far fetched and tough goal, but dammit i'm going to try.

are these numbers I can actually expect at same boost? I wonder if my head work will actually help without a cam upgrade.

Eyal,
DanP's where at 19psi. Diffrence between 56 and 57 trim is the compressor size, its back a page or so.
Big diffrence..

Hey Wes, Dan also has some head work on his car as well. Plus, he has in the ball park of 70k miles on his car and TOP shape, just as a fyi. When I upgrade my turbo (and everything else) I am looking for 350rwhp-380rwhp with full boost by 3,600 or so. I would think building boost any higher in our cars won't be that fun to drive unless you track it. With the upgrades I have in my car now it all I can do not to spin the rear for 1st and 2nd gear and that is with 8" fuchs in the back with wider tires on. Good luck to whatever you decide because I am doing this upgrade over the winter so hopefully you can get your car running by then so I can learn from what you do as well.
Oh yea, don't forget to e-mail me when you decide on everything and plan to do the install, I can help you out on it so when I do mine, I have a better idea of everything that needs done!

The trim equation is:
((Inducer diameter^2)/(Exducer diameter^2))*100
Because trim is just a ratio, a 56 trim can flow more than a 57 trim.

That was a great explaination

Well, with race gas a VR stg 3 is just about a plug and play 400whp. But won't happen on pump.
If your really determined to achieve this on pump, then you should really look at water injection. Water, as of now, is a hell of a lot cheaper then 100 octane
So VR stg 3, 22-24psi, water injection, pump gas, quick spool, plug and play and still top end and right in your $5K budget.

I have heard across the board that propper head work REALLY opens the motor up. Very restricive on the intake side and then a cam to match. Once again, sounds like VR
Bear in mind I do not have ANY VR parts; if I could only get John to burn me some chips

I spent several days in front of a nice high tech computer driven flow bench last week. I have a stock head, an old Huntley head and a NA head. They all flowed with in 5% of each other, in fact the dead stock head outflowed the Huntley head right up to .450” of lift (just short of full lift - .470”). The head work on the Huntley head actually looked pretty good….but it didn’t actually do anything.
The stock head (intake) flowed around 230cfm at .470” – pretty good, on par with aluminum race V8 heads. The exhaust was 190cfm at .470” – quite good.
Any serious gains from head work are not going to come easy, the stock size and shape is a very good design. The flow is maxing out due to runner size and not valve size, so adding larger valves will not help unless there is a lot of quality massaging done to the runners.
