Let me start off with this was done on the same Mustang Dyno as my naturally aspirated runs, so the reading are a little low. Now, let me follow that up with my wastegate is bleeding boost and I can't get past 11 psi without surging ... I need to play around with this quite a bit more in order to make more boost. I will have the video's up tonight.

Run 1: Roughly 11 psi

390.1 HP @ 6750 RPM
347.9 TQ @ 4750 RPM

Run 2: Roughly 11 psi with surging spike to 14 ... horrible run

403.1 HP @ 6750 RPM
358.5 TQ @ 4500 RPM

Run 3: Roughly 11 psi

387.4 HP @ 7000 RPM
347.8 TQ @ 4500 RPM

Run 4: Roughly 11.5 psi

391.9 HP @ 6750 RPM
374.2 TQ @ 4250 RPM

I never hit my 12 psi goal, but I will spend the next couple weeks tuning the wastegate with the EBC and make a few more runs then. I know this car has 500 hp in it easily!

Congrats Not bad numbers there. Look forward to seeing more when you get the waste gate problem solved.

wadespencer99 · 11-13-2007, 04:33 PM

Congrats! You happy?

RuiNaToR_QC · 11-13-2007, 04:39 PM

I would be happy! Man 403.1Hp =

FastCougar · 11-13-2007, 04:40 PM

Sorta happy ... sorta disappointed

I really should have driven the car around a few more weaks to tune in the EBC. However, this will give a good baseline to judge things by. I'm happy that I made the power I did with the limited amount of boost I'm running and the fact that it's on a mustang dyno. I transposed the graph into this graphing calculator: http://vlsicad.ucsd.edu/~sharma/Potpourri/perf_est.html

Here is what the dyno sheet looks like:

Those are still really nice numbers

FastCougar · 11-13-2007, 04:46 PM

Everytime he stepped off the gas, I would get blue smoke out the rear and a nice little puff from under the hood. What's happening is that when you get that instant vacuum after letting off the gas, it's sucking oil from the heads through the valve cover breathers. That oil is then getting burnt off through the cylinder after the throttle has closed and since the BOV is now open, it's being spewed onto the turbo's exhaust housing

So, no more running the car after my commute home today until I have changed the oil AND solved the oiling issue with the valve cover breathers. So, back to my question ... what's the harm in venting the VCB to atmosphere? The car is tuned and that can be compensated for, but will those filters see any oil? I suspect not since there is no vacuum on them. Someone please make an educated suggestion on this issue.
