This was done today on a factory series 5 block at 23psi (only thing changed was the oil pressure regulator):







The thread is here: http://www.teamfc3s.org/forum/showthread.p...&threadid=20300



Yet again, if you prevent any knocking or obvious misfires, these things are capable of gobs of power, even the older engines that aren't re-inforced.

It's awesome. He's got a couple of issues (not uncommon to run into this kind of thing the more power you make anyways) and I want to continue tuning it further on the same peak boost levels with the gas he's using. I think the hotside of his turbo is too small and he needs to go up one trim-size larger. He may be able to prevent the drop off that's happening at the very high 7k's to low 8k's where these engines really being to breathe well. Time will tell. I'm quite happy with it!

Thats great man. I'm happy to see some people having success with the half bridge setups. I'll be jumping on the bandwagon soon myself.



I'm with you on the turbo thing. Don't get me wrong 475/383 @23 psi is damn good but I think its got alot more in it, something is choking it.

Well, the back-end needs to go to one size larger trim-size and the exh manifold is an HKS cast undivided. It kind of sucks. We'll continue working on it.
