I know this has been discussed by Shiv and others extensively but I am interested to know if Mitsubishi has made a formal stance or rebuttal on the issue. If so could someone direct me to the past dialogue or at least give me their thoughts.

 

what are you even referring to?

 

I am referring to the inconsistent hp numbers generated by evo's. It has come to the attention of numerous tuners that there is not a consistent power rating from evo to evo. That is what I am referring to.

 

There's no conclusion as of yet. I believe Mitsubishi is fully aware of the tuner results and is working with Shiv to find a potential issue to resolve. These things can take some time, though.

thanks marks for the response. I guess I'm just afraid to get mine now with this whole sick evo phenomenon but I guess it won't hurt to wait a little. More time equals more money which results in more modifications. Anyone else with responses (shiv) is most welcome (wink wink) & (thumbs up).

 

You're painting with a pretty broad brush there. Do you have numbers (VIN's, dyno charts) to back up that statement? Manufacturuers are pretty sensitive about this kind of thing, since Ford blew it with the Cobra SVT Mustang and it cost them a recall of the entire production run. Mitsu stated, unequivocally, that the Evo would have 271 hp and 273 ft lbs of torque, no more, no less (quote from Car & Driver). Just curious if you have hard numbers or are going by anecdotal evidence from the board.

Adios,

Well I am no tuner and I do not have a dyno. However according to numerous tuners and their posted hp numbers something seems to be fishy. Not only are the awhp ratings low (this could be argued I know because of the difference between dyno's) but the incosistency of the numbers is the issue most concerning. But as you said all of this empirical evidence could just be anecdotal I mean are these sensations real and if so how is it that I come to know this information? Am I born with the capacity to know or is it just that I learn over time? But even then I would admittedly have some form of pre-knowledge. You bring an interesting point fusoquy. More on this later...

 

hhrrmmm....

Well, here's a data point for you. Shiv got 223 hp at the wheels of an STi. Assuming that the Evo makes approximately 30 less flywheel horsepower, the STi indeed makes 300 at the flywheel, and that the longitudinal drivetrain of the subaru has less parasitic drag, this data doesn't refute the idea that the Evo makes 271 hp.

 

I also heard there are is a wide range of dyno hp numbers across the EVO spectrum, from as low as 189 all the way up to near 260 at the wheel.

Sounds sketchy to me, wonder whats wrong?

Just my two cents....

 

I agree, vague references to unspecified "tuners" of unknown expertise doesn't seem to be worth getting worked up over at this point, unless there are more hard & fast data. If these exist, let’s see them. Seems just as significant that all the tests I've heard of in the press seem to come up with pretty similar performance numbers for the car. In both cases (tuners and press) you're dealing with a very small sampling of the total production.

This is driving me nuts....
As an engineer I can state a bunch of technical crap, but I wont. Heres the truth of the matter. There is no SAE method of testing awd cars for wheel hp, so each dyno owner might be doing something different. Second, I believe Shiv also tested an STI on his dyno setup and it had similar losses to that of the EVO. Now this is nothing against Shiv, maybe his dyno proceedures are different. Which brings me to my final point. Whats in a number??? The EVO is a damn heavy car, and it a good driver can pop the SOB through 1320 feet in lows 14s, high 13s, dont you think almost all of the claimed 271 hp is there, in some form or another???

I dont know, thats just my own opinion. Take it for what its worth. And to anyone unhappy with their EVOs performance, Ill take it off your hands....hehe

 

Keep in mind, different dyos=different results. You have to dyno the cars on the exact same dyno at the exact same location with the exact same gas and the exact same atmospherical condictions... Exactly!!!!:-D
Having different hp is not really all that surprising since most tests are done at different places. As the STi numbers start rolling in more, I'm sure we will see similar hp variations.

 

what would you consider a heavy car

the oour evos are what

3100 pounds

 

Actually EVO has a dry weight of 3263 lbs, dry as in no fuel, no driver, etc. So yes, the Evo is a decently heavy small car. DO the math, to push the Evo to 13 second quarter mile, how much power do you think it takes? That was my point, not to get into a weight debate on the Evo.
