Dyno run was a little disapointing, i couldn't drive it, so i didn't ride the brakes, it was boosting @ 40psi and the egts went to 1600* i hit 130 mph and made max tourque of663.67 and max hp of 276.71. The transmission seemed to not be slipping, but i was not happy with how hot the egts got and how low the power was. i didn't run an airfilter. i left the set up in my sig so i could have a bases. i got schooled by my friend he had 377 hp and 840 hp. well next step is going to be grind the foot on the afc control and flip thoes washers, i want to see how that drives, then when funds come into the play upgrade the turbo, and get some 90hp stick from ddp. i hope this will up the power. Cause i was very disapointed with these numbers, i didn't even get my score on the board.:ouch:

grind the barrel not the foot of the afc this will give you less low end fueling with more top end.

change you trubo housing to a 16cm, 18.5cm,21cm, or upgrade the turbo. that little 12cm housing is chokeing you on the top end. remove fuel plate, adjust gov arm all the way up, tune the afc, add rack plug, add head studs, set timing to 19*, and try dyno again :U:

All the fuel tricks in the world does one absolutely ZERO on a dyno without the turbo to make efficent use of it.

40psi is about at the end of the rope on a HX35 and once you cross that all you do is heat the air instead of cooling it.Couple the amount of fuel you have with the 12cm exhaust and you will see the extremely high temps your seeing.If you do not have the coin now for a charger look for a used 16cm housing and it will take some temp out of the deal and allow you time until you can afford a aftermarket turbo.

The first mod I said was a bigger housing or turbo if he can. with the extra air the fueling mods I said will make a great combo. Its all about when you bring the fuel on for the dyno to early lost of heat and little power to late no power at all. you have to play with it and find a good balance. I'm not saying air is not important because it is that determines how much fuel you can throw at it and still make power.
