    Another ESS VT1-535 dynojet dyno graph, 2011 6-speed E90 M3

    @LostMarine, this baseline on 91 octane with just a rear section exhaust matches pretty closely what you put down doesn't it?

    I would think that more octane, more psi and catless would have a bigger effect

    Nothing to do with superchargers, but why do so many people prefer to post up STD correction?

    It reads higher than SAE like this. Is this the reason?

    SAE and uncorrected are the two most important graphs with conditions shown.

    Yup agreed! Fortunately, there has been a huge step forward in others posting dynos. Now EAS is starting to post SAE, STD, and Conditions which is a lot more informative than before.

    I would be curious to see the Uncorrected results as well.

    Comparing both conditions from @LostMarine and EAS, it looks like they're fairly close.

    The one thing that I wish DynoJet would improve upon is showing the timestamp of their runs. I noticed that anytime you save the file, transfer it to a different HD, computer...the time changes. It doesn't retain the time of the actual run. I think this will also share a crucial part on how the dyno run was conducted relative to previous and following pulls.

    time stamp would be nice. I still dont like how sae and uncorrected are alwas exactly the same there.

    They must have one hell of a fan setup, i saw a 10+ HP drop immidiatly for my 1st to 2nd run

    Amen - this STD trend is annoying!

    I should write DynoJet a letter....LOL. I seriously think proper time stamping can shed light on a lot of things!

    EAS has a MONSTER fan setup. One large fan (looks to be 48") and 3 small high speed squirrel cage fans. Depending on the car, they seem to point the fans in different directions for optimal cooling.

    Yeah, I think it's great that they offer superior cooling, especially if one were to do some custom dyno tuning. I think this method of cooling is good if you want to see nice consistent power on the dyno. I am just most curious to see how much that differs from real high speed air when driving on the highway.

    I heard you can rent these fans at big department stores, which I might do when Evolve tunes my E46.

    Yes, that is the reason.

    We made 20+ whp after putting the fan directly to the filter however we do not display these results as our highest. Cooling fan placement on the dyno can make a night and day difference.
