I'll start by saying my intent was to have before and after dyno info for the new wheel but the two local dynos I use both had issues that made them unavailable for testing. Irritating, but since I don't have my own dyno, you deal with it. With a new part in my hot little hands, I wasn't willing to wait for an unknown number of weeks before I could get data so I chose to install it and get my information out and available.
Since the dyno sessions fell through, all I was able to come up with are boost and back pressure readings.
See sig for truck specs, nothing changed but the SD wheel/WW2 swap. Matt already had my tunes dialed in smoke free so there wasn't really any unburnt fuel to cleanup.
Tow tune went from 24 to 28 psi max boost (+4) and the back pressure stayed the same @ 35 psi.
Street tune went from 25 to 30 psi max boost (+5) and the BP went up 2 psi from 36 to 38.
Observations compared to the SD wheel:
Spool seems the same in my application and it should spool a little earlier because the new wheel is lighter. I may have created a leak during the R+R process, waiting to check with a smoke machine.
Feels stronger in the mid and upper ranges, EGT's appear to be the same at low boost and slightly lower and build slower at WOT.
I lost the whistle when I went from the OEM wheel to the SD wheel and was disappointed, its back with this wheel and I'm glad, I missed it.
This is @ ~5800 ft elevation
After I make sure I have no leaks and have a chance to tow with it I'll post back up.
