3 1/2 hour dyno session today
finally got my car running right and went to the dyno.I needed a base line before I install my JME Camshaft.The dyno sheets are are being emailed to me and if anyone could post them for me I will be grateful.But here are the results i remember. 344 HP,378Tq at 1.15 bar of boost.I did not get crazy with the boost because after doing 11 runs I had the fear of breakage.I also had 115 octane leaded gas in the car.But I have the call David at powerhaus and ask him why it takes 4000 to spool me turbo he claims comes on at 3000-3500.I was trying to get mid 11low 12 with the A/F ratio came close but I need more tunning.The guy only charged me $200 for 3 1/2 hours great guy.

Sounds like the guy gave you a great deal with the dyno time. What is the car mainly used for street or track? I think you should be able to get away with staying above 12:1 A/F ratio especially with a street car where it does not see the prolonged WOT that a track car does. You have a big turbo there I find it hard to believe you will get it to spool up much quicker. To help spool up the turbo you don't want it to go real rich right away you want your A/F ratio to slowly step down as the turbo starts to spool so you are at 12.5:1 by the time you see about 4psi of boost or so. If you did not do it already you might want to slowly turn up the duty cycle on the AVC-R for the first set of rpms I think it goes up to 3000 rpm if I remember correctly. I look forward to seeing your charts.

Thanks for info taz.I use the car on the street and an occasional 1/4 track times.When you turn up the duty cycle your boost increases right?I am just now learning how to tune so I need a bunch more dyno time.

I dont know if the flywheel helps,You know its meant to rev quicker but you loose a little torque.When I put it on I felt a little quicker rev time in neutral I think hard to tell with feel and sound.I know one thing my clutch heats up and gets a little vibration through the pedal.

Yes as you turn up the duty cycle the boost increases. What I am telling you to do though should not increase you boost at all. What you will be doing is not letting as much signal pressure go to the waste gate so it opens later and helps to spool the turbo quicker.

I think I would have similar power to you, do you think my slower shifts may account for some of the MPH diff? My "best" 60ft was 2.4.
