All I know is its running at 27psi using ethanol and after we fix the couple of minor things will put it up too 35 psi. There is no back pressure or flow restrictions at all at 27 psi. Sounds very strong on the dyno. It jumps straight up too 6200rpm which is where the stall is at. It will be more suited to the de stroker motor which will be going in, in the near future anyway. The 4.0 ltr is holding up better than I Thought so up the boost goes. Lol. To put power in prospective it's running ID2000 at 84 percent duty cycle @ 72 psi of fuel pressure 1 Link to comment Share on other sites More sharing options...

It needs the weight of the car to get it to lock up properly. So it's all over the place. The true and only indication is the track mph. Can't be cheated. For instance rob campisi mustang showed around 1250 hp on a dyno but ran 5.9 @260mph. So does robs car make 1250 @ wheels. No chance. You wouldn't get much change from 4-5000hp from that engine Link to comment Share on other sites More sharing options...

No chance of detonation. Fine tuning at the track is easy once we have the basic settings like we have Link to comment Share on other sites More sharing options...

I have a brand new twin Bosch 044 setup polished surge tank. Lightweight braided lines and fittings. I changed paths during and won't need them any longer. To be honest the record is not my goals anymore. They are to go alot quicker. Once the billet destroked engine goes in a new turbo and gates will also. If your interested in a gtx4202. That will need to go. It's done 4 Dyno runs Link to comment Share on other sites More sharing options...

Anyway only way to find out and that's run in :-) Link to comment Share on other sites More sharing options...
