Rage... quick question. Am I seeing steam (condensation) or smoke in the dyno runs from your exhaust? Just curious.
Sounds like you are getting there. I was guessing closer to 340 at the wheels myself. I am sure you can get it. Also, if the load is not right, as you said, you will be down on power.
Peace!

That's effectively what I did by setting the duty cycle to 100% on the AVC-R. The wastegate was completely closed. The spring might be too weak on the deltagate side, but I think I'll just wait for the loaded dyno before doing another run.

It's winter, so you can see everyone's exhaust =). It was about -10C outside that day. There was a bit of smoke on the first run at the end, that was from the tires slipping when letting off, and the dynojet was braking.
I'm aiming for the magical 400rwhp mark. I think I can do it on the dyno if I can get the boost to hold a bit higher near redline. I'm pretty certain that I'm making around the 390rwhp mark on the street at full boost. My boost and torque curve is dropping pretty steep on the dyno, which it doesn't do on the street.

Rage,
It is addictive, while I didn't achieve my previous 330RWHP and only made 320. I going to go up another level. Technodyne is going to install bigger injectors, Mod the MAF, Garret GT-25,Tial WG, and install a Greddy profec-B controller and tune everything. Last night he did a 2.5ltr with these mods and it ran a whopping 400RWHP/420 ft/lbs. That was with alot of boost-110-no pinging!

Rage, you install an adjustable cam-gear to combat that dropping torque curve. Retard the cam about 5 degrees and that should help.
You can also adjust the AVC-R to add about 1psi more boost at the higher RPMs as well.

Hey Danno. Do you think it's wise to get an adjustable cam-gear or to get myself a hotter cam instead? Any advantages/disadvantages? I don't have much experience in cam tuning, do I have to worry about redoing my timing curve on either mods?

I tried that, definately a load problem that can't be solved until their dynojet is upgraded. At 4500rpm and above I set duty cycle to 100%, boost fuel cut (SDS side) at ~21psi, the boost situation didn't change (the torque curve was a wee bit smoother). After the dyno runs, I forgot to turn the duty cycle down on the street and hit the boost limit fuel cut on the first stretch of road.

Thank's again for the invite to come out and watch! Snuck out of work for a little while.
As to pinging, I heard no pinging, but then again after three runs I could not hear much of anything!
I have not watched the video, but the drum and tires could probably been a small lose of power as they were both wet. Damn snow drippings.
Any way, talk to you later,
Doug

Hey Doug... I think all of us there snuck out from work for a few hours =).
I was in the passenger seat for all the runs, it's a lot quieter in the car. I was told it was so loud on the outside, everybody had to cover their ears. I felt sorry for my brother who couldn't cover his ears, as he was videotaping... he said it hurt =).
As for impatient me, I can't wait for those guys to get their dynojet upgraded, so I ordered a new toy... the <a href="http://www.blitz-na.com/NA_ProductsPowerMeteriD.html" target="_blank">Blitz Power Meter I-D</a>. This thing works like a GTech Pro, except it's more accurate because it reads directly off the speed sensors. What'll I do is do an on road dyno run with this sucker, use my peak tq # from my real dyno run, map the curve from this unit on there, and I *should* be able to get a pretty accurate "on road" dyno (assuming my 404ft/lbs of torque is the highest I achieve on the road).
I think I'll have the thing in a week, of course we'll have some nice pictures and videos of the unit =).

Hey Rage2, do you have the original data files from your dyno runs? I would like to use with my PepViewer software to draw up some comparisons with other cars.

The MAF and the Turbo I have makes 350 @ 18 PSI The Stand alone of rage 2 and more boost should easily make 370+
also if you compare teh power /PSI you make and at which levvel then you can just multiply the more PSI to see the more HP you will get. 370 KP at 20 PSI is very realistic if you have no leaks and teh engine is adjusted properly?
BTW where and how did you tuned the Satnd alone management? Dyno? road? both?

Based on races with other high powered friends (I know their weight too) I'm guessing I make around 370rwhp at 5200rpm. I'm getting the Blitz Power Meter or the Racelogic AP-22 to graph a road torque curve to better estimate my power (until the dynojet gets upgraded).

There is a small leak right now in the intake gasket, that's getting swapped out this week. Really minor, nothing major. All my tuning have been done on the road. It's the only place I can build up the boost.

Rage2,
I am considering Engine Mgmt. in the future and have a couple of questions.
Besides the tuning advantages/less restrictions.
Does the system shut down, have alarm ect.. if you go lean do to a injector failure or something?
