Default Got my car dynoed this weekend.

Turbo is a T3 .48/.60
DSM 450cc injectors
BRE on my PR3 ecu
Joseph Davis tuned my car. When we were tuning it, we couldnt get datalogging to work for some reason, so we were looking at rpms, vaccum/boost, and wideband readings....It actually turned out pretty good. AFRs stay around 12.5 all the way until it gets in vtec(~4600rpm), then it drops to 11.4 and gets back up to 12.5 at about 5500 rpm.
2.5" dp to 3" exhaust
tubular home made manifold
2" to the intercooler from the turbo
2.5" charge piping after the intercooler
2.5" turbo CAI in the fender well
Type S bov
62mm tb

Here's the video:

And heres the graph.

7500?

I guess the turbos a little on the small side, every B-series I've ever dyno'd peak power was always at 7800-8200

i didnt have datalogging when i dynoed, so i did the same thing. held the car at all the different map columns by lookin at the vac guage and then dialed in the a/f ratio for each one (the dyno was able to do load tuning you could hold the engine at whatever rpm point you wanted)

I'm not sure why it says 7500...He took it to at least 7900 and it bounced off the fuel cut....dunno why it came in early. Should be at around 8300...must be the 17" wheels

but yea,most of the guyys I know that dynoed, it ended around 7500 on their graphs too....weird...

I think there was a problem with the dyno's inductive pickup... plus ground problems in Josh's car... which explains some of the mayhem + dissappointment over the weekend.
