EVO X dyno comparisons

[David Buschur]

Well I wanted to see how our EVO X would do on a Dynojet so you as customers could compare our numbers to most others that have been put up on Dynojets.

I gave Tym Switzer at Switzer Perforance a call and asked if he could get me in today for a few quick runs. Want to say thanks to Tym and the fellas over there for getting me in and allowing us the time to see what we could make.

First some details. The dyno runs that we made here produced 407 whp and 341 ft lbs, that was on our Mustang Dyno AWD500SE dyno. The dyno run was done in 3rd gear, I do not use any correction factors on our dyno, ever. So the runs on our dyno would be "uncorrected". I also did the runs from 2500 rpm to 7500 rpm here on our dyno. Boost was set at a peak of 24.7 psi.

Now to the Dynojet. Same things were done. 2500-7500 rpm, 3rd gear and we ran the car uncorrected.

The first few pulls the power was not as high as I had expected. Tym suggested the boost may be off between the two dynos because our Mustang Dyno loads the car differently. Sure enough a quick check of the boost and we were only making barely 22 psi. A quick boost adjustment on the BR inline controller and the boost hit right at 25 psi. The power jumped right up to what I had hoped for.

443.23 horsepower and 383.75 ft lbs of torque. Very impressive. This is on STRAIGHT 93 octane at factory peak boost levels.

Here is the dyno sheet:

WOW, I am really giving serious thought to picking up a 10 when I get out of school. Well by then they will have the XI out hahaha.

Wow, basically 40whp (50flyhp) difference between dynos. Hello!!! That basically sums up the variation from dyno to dyno perfectly. So, how does one try and estimate power at the crank/flywheel? You can't just take the typical powertrain loss (typically what? 20-25% for an awd car?), it will be the same percent different/off as when comparing dynos.
For example, if you take 25% loss at the BR dyno: 407whp/.75 = 542fly HP and on the Dynojet: 443whp/.75 = 590 fly HP.

Does each dyno have a manual or guideline to help understand crank hp?

In the end, I guess it doesn't matter. If you stick to the same dyno, you're main goal is to compare changes relative to previous runs on the same dyno.

Thanks,

David...with these new horsepower levels reached on the X, ever think about retesting the unnamed downpipe to see if there are any gains at these elevated HP levels????

[David Buschur]

I don't plan on retesting the 02 housing downpipe we tested last time, I don't have it, it's on the customers car. We are going to test a downpipe again on it when we get some time.

[Bionic Dead]

I'm thinking that there will be a difference this time. We will see

[David Buschur]

There is no calculation for flywheel horsepower on our dyno.

The EVO 8-9's were rated at let's say 275 hp. They made 215's on average on our dyno.

Hey Dave, if you come up with some upgraded clutch packs for the MR's you can try out the Dominator 2.0 and cams on my car for the comparison But I will not be raising my power levels until we can make sure it will not destroy my clutches

Well Keith.........................we don't do transmissions upgrades on auto's. We'll be waiting for someone else to do that.
