Message Stopped by the dyno shop to make a few pulls this afternoon - they were busy but fit me in to make 3 power pulls for $60. I've just been dying to know what kind of power she is making.

These results are UNTUNED - I simply loaded the car up and made the pulls on 93-octane pumpfuel. I will return sometime next week once I burn off 3/4 tank of pumpfuel and load her up with some C16 and do some ZEM tuning.

The first pull was done at ~18psi - the boost controller was doing some strange things and I made some changes and the second pull I aborted as the boost shot up to around 23psi, but you can get an idea of how quickly this thing spools. 539ft/lbs of torque at 4500RPM in that stint, LOL.

The third pull was a bit more stable with the boost, but you can see the double-hump in the torque curve as a result of the boost wanting to creep a little from 18psi to 20psi.

I have changed the boost controller over to auto mode where it will self-learn the boost curve and on the way back after a few street pulls, she was coming up steady to 20psi.

The Blitz power meter was telling me the car was making 560RWHP on the street and it looks like it is DEAD on the money.

Here is a dyno comparison between my vehicle and Dee Ridgeway's TT - both are on pumpfuel and 1.4bar: My Z is in the green, Dee's is blue:

Here is a dyno comparison between my vehicle and Rob Dawkin's Sport500 vehicle: My Z is in green, Rob's is in red.

As you can see, this setup is very responsive - the lag is only beat by the Sport500s until 3750RPM and way ahead of the game above the GT28RS with the .64 A/R turbine housing, not to mention, there's almost a 50RWHP improvement over Dee's setup at the same boost.

I'll get this pumpfuel burned out and return to the dyno sometime next week and do some final tuning with C16 - given the current results I'm pretty confident in seeing some more impressive numbers when we turn everything up to 11. :)

Thanks!
