I am not too impressed with my dyno results but I dyno'd at 202 wheel HP and about 252 to the crank. I have a Turboxs.com stage 2 kit which is a turbo back exhaust, catless up-pipe and Utec piggyback ECU. I was told and hoping for more like 215-220 Wheel HP with about 275 to the crank.

With the stage 2 I was told I would be running mid 13's. The AWD drivetrain loss sucks but there is nothing I can do about it but add more mods for more HP. Anyways here is the dyno chart....

what were the gains?

 

Do you have a A/F graph? You may be running rich

 

the gains are 160 WHP to 202 WHP and 220 att he crank to 252 at the crank.

and yes i was running a little rich, but could running just a little rich between 5300-5700PRM's cause that much HP loss?

maybe it was the dyno machinethe dynojet 3300 i think they used they took all the wheels off and mounted the lugs to 4 machines. who knows.....

 

i heard lots of good things about vishnu, maybe give them a try

 

these gains seem to be in ball park for exhaust and chip add ons.

 

Should have kept the maxima Jay.

 

well they did more then 6 pulls on the dyno and it was running rich from about 5400-5700 RPM's and I dont know if thats normal or not for a TXS setup. The boost was set at 15.5PSI and I honestly dont know what the temps where.

I mean if the kid at Pruven with a stage 1 was getting more HP then my setup something is def wrong. He got 20 more wheel HP then me without an up-pipe, and turbo back.

Different Dyno's produce different numbers yes but such a drastic differenct? I was told I should be realistically around 220-230 wheel HP and about 275+ crank HP.

I am not saying that it is tuned wrong but maybe tuned a little too conservative. What do you think?

 

running rich will slow you down some. what is included in a stage 1 set up, i am not familiar.

 

Talk to Synki.

 

Should of got a Z 12.79 with 5.6 psi.with greedy kit. My future dream.

 

the stage 1 is the Turboxs Utec ECU and the stage 2 just add the turbo back exhuats. The car runs rich from the factory and the TXS kit is sort-or rich running from what I have been told. The A/F runs rich from 5400k-5700k rpm's. What do you guys think. It was a dynojet 5500 which mounts to the hubs....

 

252 at the crank seems like a lot of hp to me. the wrx is a rwd/awd car, maxima is fwd. apples and oranges. wrong answer!

 

i thought the AWD of it kept the majority of the power to the front until they start to go giving more power to the rear ... isnt it split like 70front/30rear

 

AWD usually has the majority of the torque biased to the rear wheels if anything. The WRX is 50/50 under normal driving conditions but sends more power to the front or rear wheels as necessary to maintain traction.

 

It really depends--say you go AWD on a Carerra, Benz, BMW, you see what I mean, cars that are RWD without the AWD option--once AWD, those cars send the majority of torque to the rears. The cars that are usually FWD, when they go AWD they still send the majority to the front, which kinda keeps the handling poor. It's simple physics, you cannot expect your front wheels to both drive and steer and have that be the optimum handling. That's why it was no big deal when Volvo had 268 HP on the S80 T6, it was FWD so the power cannot fully be taken advantage of. Funny how their what, 97 car has more power than the 2k4 Max, 7 years later!

That's why I was pleasantly surprised to find that the WRX is really AWD with a RWD bias. No way no how a Maxima can touch it in handling, to say otherwise is only sour grapes.

 

a 42hp gain is pretty good, especially with all wheel drive. but many people have been seeing gains of 30hp with ecu and catback. on that type of level, your uppipe would be producing around 12hp, which sounds about right. you said your car was running rich from the factory so you may want to get that fixed/checked out.

a 42hp gain for the stage2 sounds about right, but your overall hp is a little low, so i dont think its the mods, its the car itself.

just some thought

 

nymjayjay OT but do you think the stockers will hold up fine w/ the eibachs?

 

o/t but your b.o.v sounds peeeeeeeerty

 

There is something wrong. Is your ABC set right that came with the UTec?

You might want to post your map to Phil or Nathan @ TXS. TXS will be at XX Tuning (I think that is the place you went to).

When you were getting dynoed tuned, did you have any knock? If you have knock, that will pull a good amount of timing away and drop big time in HP figures. Also, are you running colder plugs? That would be a good idea since you are running more power.

I still think it has something to do with your tune. It seems like the UTec is pulling timing and that is robbing you of power.

Pruven Perf does wonders with tuning on the UTecs as well.
