Interesting....

So the difference in acceleration noted by many magazines between the VIII and IX must be almost totally caused the by the gearing change.

Mr. Buschur, heres the million dollar question. At this point does the addition of the Mivec head provide for more power to be untapped in the future, or will gains seen on the non-Mivec 4G63 be similar to the new engine? I understand this is early in your development cycle, just wanting your gut feel.

whats the point of the all so great "mivec" if theres only like a 3hp difference? cheeeeeeeeeeesy

zectasy - Mivec might be useful for future tuning endevors, hence why I asked my question....

It would have been great had these dyno runs been done at the same time of day

Dave-
Stupid question, but do you think after break-in these IX's are going to dyno higher? I didn't think there would be a significant increase over the VIII's personally given the minimal upgrades, but I thought I'd put it out there. . .

Thanks for the realistic numbers, the more performance savvy group here in EVOM appreciate it. . .number inflating is just ghey.

I'm happy I'm waiting for the X to trade in my only 10 week old 8!!

probably doesnt matter since he said he dynoed two IX's and the results have been consistant.

Exactly what I was saying in the other thread. Oh, and that quote in your sig about driving the evo is so right. No one at my job understands why the car is so great. I told them to drive one.

Personally - I was not expecting much difference; they are advertising these at 285hp/289tq. I think what some of us are waiting to see is what kind of an effect a TBE & Flash are going to have on this MIVEC - and then some

Evoviiiyou, I have no loyalty to Buschur, to Tym, to Mustand dynos, or Dynojets, so please hear me out...

The Dynojet seems to be the most commonly-used when comparing figures, and it is how _I_ compare my car with others, as well as other cars against themselves. When I see someone hit 350whp on a Dynojet in an, I expect them to hit 115mph. If I see 400, I expect 120...300=110. It's easy to compare and contrast when the whp/mph is so linear given similar circumstances. The problem, though, with Dynojets is that they are not good for tuning. It is commonly accepted that the Mustang Dyno simulates real driving moreso than a Dynojet, which means if you tune a car on an MD, then that same tune will carry over perfectly to the street. To the contrary, a car tuned on a Dynojet CANNOT expect to carry that same tune back to the street and have the same effect. This is a conundrum within the tuning community, because a Dynojet owner may tune 10 cars and come up with some great power numbers with great AFRs and timing, but then those cars go out on the street and have different AFRs, different timing, and obviously different power output. I have been on 2 different Dynojets in this area, and all of them were a good tool for seeing where my power was relative to others in the area with the mods I had, but the AFR readings were COMPLETELY different on the street than what I saw while stationary in the dyno bay. Whatever I tuned for on the dyno was not optimum for my daily driving each time, so I had to re-tune for the street. That is what DB is talking about...

That EVO8 torque curve looks really nice, but my stock EVO doesn't feel like that at all, it really seams to fall flat after about 4500rpms. I expected to see a fuller flatter torque curve from the EVO9. Could it have been the ODBII adapting to the driving style? The EVO9 is not as impressive with peak numbers as I had assumed. Can you show the area under the curve?

Now this is just stock WOT numbers? Did you do any part throttle runs? Does the EVO9 spool up any faster in normal driving? How is it off boost?

Peek numbers really don't mean all that much, how many of us drive WOT all the time?

You can NOT compare dyno numbers from different dyno's. if you start to tune your car on one, stick with it. Numbers are just that numbers, as pointed out, real world results speak for them selves.

Thanks for taking the time to explain this to me...I meant no ill will to DB or the mustang dyno. I appologize if I came off sarcastic! I guess I wish there was one dyno manufactuer that every one had to tune on and go by. Sorry again if I offended anyone with my comments.

I just posted this same question I am about to ask in David's other thread (EVO IX exhaust and BR-350)

I see that the evo ix had only 14 miles when dynoed. Can it be that it's not fully broken in yet, so it's not laying down all the power capable?? Also, who many miles where on the evo viii when it was dynoed, and was it fully broken in????

evoviiyou,

Very classy response man. It's nice to see people on this board express different opinions and keep in mind we are just sharing information and it's not personal. Very Classy.

I see no point in comparing these results to the Switzer Dynos. After all, didn't the white rabbit put down 440 whp WITHOUT cams on that dyno, which has YET to be even come close to?


Glad to see the 9's aren't making too much more power...otherwise I'd get jealous
