Dyno day for the All-trac.

Postby Trumanpriest » Sun Nov 20, 2011 6:30 pm

Had a Dyno Day with some guys from MR2OC in Saint Louis area today, and they had an AWD DynoJet so I thought I'd share a video and the graph. Not too bad for a relatively stock setup with a CT-20B at 1bar of boost.

facebook video - not sure if it will work this way or not.

The Below image is hard to read I know, bust I could do with my camera phone. 242 AWHP and 237 ft/lbs of torque

When we tried turning the boost up past 1 bar she actually did worse than at 1bar. They said she didn't boost as high. What could be the cause/solution for that? Was I likely loosing pressure on a fitting not able to handle more than 1 bar of pressure? Fuel was still very rich at 1 bar, so I don't think it has to do with that? Could it be timing? Would advancing the timing give me a bit more since I run so rich? I'm just curious....

Not bad numbers at all, Kinda surprised your not still building power past 5.5k. You could flatten out that torque curve a bit between 2500 and 4k buy getting the TVIS to open right where it dips at around 2800rpm.

Without seeing your set up its hard to diagnosis why It wont go past 1bar
