I catered a dyno day on Mother's day (horrible car guys!) at the local FSR Motorsports shop for a BMW site. They ran out of m powered and supercharged monsters, so they threw me up on the dyno. You can see my catering equipment in the back as we dyno'd. I wasn't planning on it, so I didn't have vag com, or a vid camera with me. Impromptu dyno! At least the datalogger was there.
Boostvalve
I was having trouble making a home made boost valve work for the longest time. We made a couple, bench tested them, and they would bleed at partial/midway boost. Causing some extra lag. So I gave up on them. I got a real boostvalve in, and it seems to be doing it's job now. I didn't think the homemade would be a problem, but it seems there is a seat cut for the bearing that I we didn't account for. I had even bench tested another members boost valve a while back and it was acting funny too. I'll need to take real logs to prove it that spec and actual are meeting correctly.
Dynojet
I had to get a dyno run in here since its been the main dyno we've been using. Lower than I expected, but I guess
that Mustang and
this Dynojet are pretty close. The WCF that was a concern about wasn't really that off.
First two runs, the valve was clipping it too early, and causing the boost to go a bit funky as it was underboosting then correcting.
#3 run is the good run that the boost valve held 32psi all the way through.
IAT hit max maybe 120*F
EMP was 1:1, got to 40PSI by 5000rpm
Smoke is a bit darker then some other runs I've had, but I think theres some relation to the reset timing (regular advance timing) we had on there. My phone's video ate it.
