Hmm, on my dyno the EVO's lay down about 230-236 whp on average. I have gotten as high as 330 whp on stock turbo and stock camshafts/internals/clutch/trans. This is just on 100 octane unleaded fuel. I expected at least a 100% increase in power out of the HKS 3037 kit. What did Al lay down without nitrous, anyone know?

The Great Dyno Equalizer
AWD Driveline Input Approx.
Chassis Loss Desired Required
Dyno Type Multiplier Flywheel Wheel
HP HP
-> 546 <-
AWD Dyno Dynamics 1.40 390
www.dyno.com.au
AWD Dynapack 1.19 459
www.dynapackusa.com
Dynamic Test Systems 1.03 530
AWD Dynojet 1.19 459
www.dynojet.com
So roughly on a dynojet you would see 459 WHP with a stock motor and a bolt on kit. Not bad at all. Plus as Shiv stated this turbo was running out of steam after 6000 rpm unlike our 3037 kit. The difference at redline was around 70 horsepower between the two kits. You cannot compare a built motor to a stock motor for horsepower comparasions as the built motor is running different compression ratios, has head work, possible intake mods, and more than likely an upgraded valvetrain to run 8500 rpm +.
This car makes 65 wheel horsepower more than the last 996 Twin Turbo Porsche we dynoed, and 60 WHP more than the last Lamborghini Diablo VT as well. My bone stock 1997 GSX(since we seem to have a few DSMer's on this thread) made 144 WHP on this dyno. So around 250 WHP more than a second gen Eclipse with a stock motor and bolts ons.

To give you an idea of how differently dynos can read, Turbo Magazine just called to me to tell me that our non signature dump-back exhaust, on their otherwise stock project EVO, made 31whp (for a total of 260whp). This is on 91 octane gas as tested on the DTS awd dyno at XS Engineering.
On our DD dyno, to make 260whp, and EVO needs a dump-back, XEDE, and sometimes even cam gears. With just a dump-back, we'll be lucky if it puts down 225whp. Heck, on a DD dyno, the maximum hp we've been able to get, so far out of a stock turbo (with a cat, that is) is 300whp which requires cams, exhaust, pump, XEDE, gears and race gas. On a Dynojet, we can make 300whp with just an XEDE and exhaust, running 93 octane. Completely different ball game.
So, 390whp (on our Dyno) is certainly nothing to sneeze it. That's roughly twice as strong as the stock EVO. In drag race talk, this 390whp should still be good for 120+mph trap speeds.

I don't recall what he he claims to have made on the AWD Dynojet he uses. But with NOS, it is appearant that his car, with Nos, was putting less power to the wheels than our non-NOS Stage 2 car. This is judging by respective 1/8th and 1/4 mile trap speeds. And our Stage 2 car "only" makes 440whp on our DD Dyno. The numbers work out quite nicely. Just need to compare apples to apples.

Sadly, at the time I was using a nightmaresih Autronic ecu which would not properly function - however
There is a lot more power in store in the near future
BTW - IF I wanted more top end power, I would simply order the BIGGER HKS back housing and wala big top end
However - I want low end so thats why I have ths standard back housing
