Just got back from dynoing my Evo8, went to Turbochargers.com where they were more than helpfull with the dyno. Good bunch of guys would recommend them.
FYI: I have 3"turbo back exhaust, no cat, SAFC, and a AVCR (set to 19psi) still have factory filter intake etc:

oh and my a/f was around 11/1 all they way to redline to keep it safe. I am expecting to make more than 300whp when I tune it out next week and raise the boost to 21psi. Can't wait to get this to the track now and see what I can do.

I am attaching a pic of my graph for those who would like to see, the dyno was done on a 4 wheel Dyno Jet.

 

Nice chart. Did they play with your turbo at all ?

 

odd I have simiar setup etc.... doing 273 only.... gotta tweak.... what type of dyno, dynojet?

isn't that tourqe number kinda low...?

 

I dunno, my tq was low also.... dunno why....must be a/f related

This was on stock turbo, I am also in Houston which is near sea-level, and today's humidity was also low at 33% which might have something to factor in. I also learned that the cooler thermostat actually loss 10hp. So I went back to factory and it runs much better. Next week I will go back to the dyno and tune it for 21psi and I am also installing a 3inch o2 housing, and a fuel pump upgrade. I hope to break the 300hp mark. I think the dyno was a four wheel inground dynojet atleast that is what they said not sure what model though.

 

Nice #'s!!! So what was your HP when you ran 12.9 @107?

 

nice numbers...
