First Dyno Pull After Getting Broken In

Ok, so here is the deal. I was already suspect of my wastegate actuator going into this, but really wanted to see where I was at. I was surprised by the horsepower number and dissapointed by the torque. I was especially surprised at where in the powerband the #'s came. To convert kilopascals to pounds per square inch, divide the kpa value by 2 and then again by 6.9

I am kicking myself in the ass for forgetting my video camera, but I am going back in two weeks for a retest cool.gif

I am open for comments, hypothesis, or ideas for why they turned out the way they did.

final result was 294hp @6900 rpm & 293 torque @4400rpm

All this while holding only 16 psi of boost. I had one initial spike to 20psi that faded fast.

I eill be getting my new actuator and stronger CBV spring next week.

BTW, Mustangs run about 8% more conservative than a Dynojet. wink.gif

Ok, so page one is upside down and the editor will not work. sad.gif

Those are nice numbers, as you know, never be dissappointed by numbers on a mustang. I am sure that turbo won't even start to make happy numbers til you turn it up. Other than the engine build maybe changing rotating mass alittle, the reason for the build was to turn it up Im sure. mid 20 psi and lets see then. Assuming the car is on pump gas, e85 would wake that tq up alot to.

Not according to Dublin. Nice numbers.

What tune are you running, It looks pretty good!

Can you drive your car normally, or Like I had to before , full throttle or no throttle ?

I am going back to dyno after installing adj . press regulator , that will be probably next week

I am running an MTE tune that Marco put together for me. Car is very drivable. Tranny downshifts at the first breath of boost and the engine pulls strong to 7k. Can be abrupt on the transitions sometimes. For instance today I was rounding an on-ramp in the rain and I pushed on the throttle (lightly I thought) next thing I know the tach is showing 6k and the car is understeering badly into the corner with the inside tireing smoking viciously. Gotta remember drving on egg shells in corners

Nice WHP - odd that the torque numbers are not higher...

Rather rich AFR's, probably could get quite a bit more out of it.

I agree, but who knows, maybe he is running a good amount of timing . . . rich a/f = more timing | lean a/f = less timing

Wonderful results!

For a comparison, my 13.3 at 107 setup made ~250 whp on 14-15 psi with the 19T... It was at 22-23 psi that I was trapping 107. I could see 110-112 trap speeds in your future without a turbo upgrade.
