    Default EVO X dyno comparisons

    We are starting to get a decent database of EVO X runs now. I'd like to show the baseline dyno runs of three EVO X's, bone stock.

    The lowest numbers were from our personal car that had no miles on it. It also had the fuel that the car was shipped with from Japan in it only. I blame the 0 miles and piss fuel for the lowest numbers of the three cars. The other two cars in the dyno graph had about 1700 miles each on them with 93 and 94 octane in them.

    Here is the dyno graph from three stock EVO X's.



    Next up is our stock baseline run compared to our EVOX now with our "offroad" Stage 3 kit on the car.



    Now for a bad ass EVO X set up for road racing. This is the sweetest looking EVO X I have seen. Jarrod started another thread about it. Grey with the aero package, full Robi Spec suspension and Enkei wheels. This car made great power and has our Stage 3 kit on the car.

    Stage 1, Catback, air filter kit and reflash (using optional manual boost controller)
    Stage 2, Upper and lower i/c pipes and MAF pipe (this car does not have the MAF pipe yet)
    Stage 3, Race FMIC

    **Note this car is also still on the STOCK cat and downpipe. Check out the improvements!



    Last is the comparison of the stock EVO X with just a reflash, NO aftermarket parts what-so-ever. This is just timing, MIVEC, AFR and boost being adjusted in the reflash. Great bang for the buck.



    The cars are really coming alive now with the tuning. Mine feels superb. If the clutch will hold up to the new found torque gains I expect to see some new times from the car this weekend.

    Enjoy.

    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.
    The great turbo debate continues.

    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,
    Chris

    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????

    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.
