HKS cams and AMS tune.
We are not talking about rally cars - those are DESIGNED to be that way specifically to meet the rules. My comment was not a sweeping generalization for every car - the Evos in question here are NOT designed to do that, and it is not a good sign for a standard-modded Evo on pump gas and 22psi to be making 40-50 more peak WTQ than peak WHP - that is a bad sign and is not good for the car if it's truly happening.

Making 40-50wtq more than whp is in no way a bad thing.
Explain why it's bad.
When Evos are setup like this, sometimes they have problems that result in steep WHP dropoffs on the top-end. Sometimes, it's knock caused by the extreme boost being run on the low-end that causes timing pulls that carry through to the top-end. Sometimes, it's a boost leak that manifests itself as RPMs increase due to the hairdryer effect, and sometimes it's knock from the extreme stress put on the motor when pushing so much torque so quickly so low in the RPM band.
I don't know why you're fighting this the way you are and attempting to belittle me here when this stuff is quite obvious and well known. You show me some examples of stock turbo'd Evos running numbers like this on 22psi and/or Evos running numbers like this on mega boost and high octane where it's normal and without problems.
Anyway, so far you've ignored what I'm really saying and are attacking things you THINK I'm saying. It's not a bad thing to have torque. It's just a bad SIGN for a stock turbo'd Evo running 22psi on pump gas to have such a large discrepancy in WTQ/WHP, because it indicates problems with the car (or with the dyno).
I have to say, for once, im not disargreing with Warrtalon. My car at 22psi made 320whp and 295wtq on the mustang dyno. Running alky and 28ish psi my car made 333whp and 342wtq. The boost would spike high to make all the tq and than by redline im back down to like 21ish Psi. I also have the Forced Performance WGA and the stock turbo still cant sustain boost that high to make the HP at the higher revs
Yes, it is very much a bad sign on a stock turbo'd Evo running 22psi, because that is now how an Evo makes power at 22psi. The way we get big torque humps like that with the stock turbo is by running a ton of boost (race gas or alky/meth). Even then it's only a 20-30 point difference, and that's only due to the inefficiency of the stock turbo at high boost levels. It cannot sustain the boost levels required to hit such a high torque level and thus peters out as RPMs increase thus resulting in lower peak WHP numbers due to the obvious hp/tq calculation.

Do you even know how you would make more wtq than whp in a turbo car?
If you want an example, my completely bone stock 03 made 218whp and 244wtq. I have a dyno sheet. My friend's IX made 386whp and 411wtq. Some cars make higher torque, plain and simple. It's usally V8s that do it, but none the less. Check power and torque figures on a turbo diesel. They make 2-3 times the amount of torque than actual power. It's not a "bad sign" or necisaraly anything wrong with the car. I don't know about you, but I love torque and would be happy as **** to be making that much more torque without perposley trying to.
I'm not trying to belittle you, but when you just say it's a "bad sign" with no kinda backing or proof, spouting off a bunch of bs that's just speculation, you bring it upon yourself.

So what are your implying? SE's should be making more power than 350whp @22psi with BPU + cams? Or that all SE's come with boost leaks? The car was obviously logged with no knock or an exceptable amount of knock because mike knows what he's doin when it comes to tunning. It could be due to colder weather, only a back to back compairison will tell. But in no way is it bad.

+1 ^^

like rally cars that make 300whp and 450wtq that's really not a good thing huh
I agree something is odd but with the readings but nothing bad.
