Well... we dyno'd it :)

Let's see, the Evo weighs ~200lbs more than the WRX. The WRX runs 94 to 95mph in the 1/4. The Evo runs 101mph in the 1/4 (R&T). That is 6 to 7mph faster than a WRX.
yet these dyno results show that the Evo only has 20hp more than a WRX at the wheels. Riiiight.
Sorry, the performance numbers of the stock WRX and Evo and the dyno of the stock WRX and stock Evo do not add up. The Evo obviously has more than 20hp on the WRX.
It is possible that he just had a load of crap gas. And Mitsubishi ECUs will retard timing and drop boost when they sense crap gas (knock for a certain number of cycles). Just putting good gas in won't fix it unless you drive around on it for a while or reset the ECU.

Well, I'll expound on this later, but:
20hp difference doesn't mean anything in the absence of information on gearing, torque curves, rubber, and drivetrain losses. There's a reason that 5.0 mustangs used to be considered quick even though they only had 215hp.

If there is one more post in this thread about the SRT-4 and comparing it to the EVO...well Im not sure what Ill do, but the delete button will probably be part of it.
The SRT-4 is a good car. The Evo is a good car. Enough said.
Comparing different dyno numbers is irrelevant. There has already been another dyno test where the EVO was putting much more power down than in this test, and that would be more relevant to the SRT-4 since this was a 2wd test.
Regardless if you want to discuss the two cars, start a new thread in the Other Cars forum.

Gas Quality and Differing Dyno's.
I'm involved with the guts of manufacturers figures, catalogs and other data. I don't think MMC lied actually, I think the simply took the best figures from a well-worn in engine that they had made sure was in top tune, ran it on the best gas available in the States, and went with those numbers.
Or, to put it another way - I have a feeling that if you ran an Evo 8 JDM and an Evo 8 USDM next to each other on the same gas (that has been used long enough for the ECU to adjust to it), they would always report about a 30-40awhp difference. Shiv's dyno read 212-230awhp for the Evo VII, which is about 305-310hp on proper AWD dyno's in Japan. So if the USDM Evo 8 is 271hp via MMC's claims, that's 36-39hp less than the JDM Evo VII - about the difference between the two cars on Shiv's dyno.

Hi Paul,
I am having a hard time understanding this. If the Japanese has in fact 310 HP and
has underrated the car (276hp). They should not make a think the US Evo only has 5 HP less than the Japanese one. That in my opinion, would not be fair to the us customers. Am I messing something?Thanks,
It sounds to me like some on the boards are bitter, because the Evo only has 20 more HP than the WRX.
Personally, I think it is funny! You pay 10K more for 20 HP.
Shirokuma, so what's up, the FHI dyno's read more realistic #'s than the MMC dynos in Japan?

The Evo is faster, MUCH faster than a stock WRX.

Dynos can lie. Actual performance doesn't. The Evo is heavier than the WRX, and has trap speeds that are 6 to 7mph faster, yet it only has 20hp more? It doesn't add up.

I dont' know about you guys. My dyno is always on the 1/4mi track.
I'm confused. A test weight of 3440lbs. trap speed of 101.5mph.
((101.5mph/243)^3)*3440lbs from R&T
Which equal to 280.75hp.
So my question is add 200lbs on your WRX and run a 101.5mph trap speed and tell me how much hp does your car have. 255hp right
