    • Truth in numbers, dyno testing the IND Green Hell ESS VT2-600 Supercharged E92 M3 - 503 whp on a Mustang

      Over time, we all mature as car enthusiasts. Priorities change, and the things that were important when you were modifying cars at 16 years old lose value as you age and learn. If at 16, having the coolest look was more important than anything else, then perhaps your early 20s are a never ending quest for the most possible power. Most enthusiasts that have fought their way through hundreds of track events, destroyed engines, and years of sweat and effort will eventually quest for something much simpler. Most enthusiasts with a solid decade of experience will want nothing more than a car that works well, reliably. Reliability is everything. An increase in power is worth nothing, if the car fails to perform in it’s designed settings.

      It is for this reason that IND has never been in a hurry to dyno our ESS Supercharged project cars. We don’t care how much power Green Hell, Blue Max, or the Silver Standard make. What’s truly important is that the cars start every time, and drive thousands of miles day in and day out, on and off the track.



      Of course, when you take photos like this, people are bound to ask questions. Curiosity gets the best of people, and “it runs great!” just doesn’t cut it after a while. We knew we had to see what the car could do.

      The internet is a harsh place, and with many shops diving into a fray of accusations, we knew we could not simply go to any dyno. We had to work with the best. AMS Performance has been creating record breaking cars for over a decade. Their 1000hp creations have victories in Time Attack, Texas mile, outright engine horsepower records, and more. AMS has been winning tuner shootouts, track events, hill climbs, and drag races for more years than most shops have been in business. Best of all, AMS’ bread and butter are Japanese cars like the Mitsubishi Evolution and Nissan GTR. Because AMS is not an active player in the E9x M3 market, they have no vested interest in skewing numbers in one direction or another. We knew working with AMS would be the best way to ensure honesty.
      After struggling and asking personal favors to get a time slot on their dyno (the AMS dyno is booked 3 months in advance with work), we finally got an “emergency” shot last week. We were told to come at 10am for our shot. Coming a bit late would mean getting told to turn around and come back in three months, when the schedule is more free.

      We hit a minor bump in the road when we arrived at AMS, and realized they had replaced their DynoJet dyno with a new Mustang all wheel drive dyno. Because most of their clients own AWD cars, AMS preferred the Mustang’s AWD capabilities over the old DynoJet. This threw us off a bit, as most of the M3 community seems to prefer DynoJet numbers, but we decided to press on regardless. AMS tells us that the Mustang reads exactly 8% lower than their old DynoJet, every single time, every single car.

      After listening to the deafening 8,000 RPM scream of Green Hell’s Eisenmann Inconel exhaust with Akrapovic GT4 x pipe, we walked over to the computer to see the numbers- not bad! 503 wheel horsepower, equivalent to 543 wheel horsepower on their old DynoJet dyno, according to AMS’ calculations.

      Green Hell has this power setup:

      ESS VT2-600 kit, with 92mm pulley. VT2 injectors, VT2 tune.

      Akrapovic GT4 x pipe, no cats and no resonators.

      Eisenmann Inconel rear muffler.

        Those numbers seem to be spot on as is the dynojet estimate.

        My main question is, with the different pulley, what is the boost at?

        only 503whp. with that SC? is like like 6lbs of boost?

        503 on a Mustang = 550+ on a dynosaurjet

        What kind of 1/4 mile traps or 60-130 times does this car produce? That's of more interest, real world performance.

        They understand, this is just one part of that. We aren't going to fault for data being provided, just a piece of the puzzle.

        So, they admit to not making as much power but now they try to say the reliability is what makes their supercharger kits special?
        People use forced induction to make power, not to increase reliability. Even with an SC it should be expected that reliability will stay at a constant unless you are pushing massive boost.
        Look at niterider, he has plenty of miles on his car (which is very reliable) and makes endless power.

        I am starting to get fed up with ESS claiming that they are better than the competition, especially when a reliable company such as IND bows down and takes it from them in the ass.

        That is not ESS speaking, it is IND.

        Even Dinan has their conservative customer base. Some guys don't care about having the most power. I do agree with you though, many people want power, people like you and I.

        Don't aim your frustration at ESS at IND. If anything, IND stated they would have liked to see ESS step up to the dyno competition as well. I wouldn't call that bowing.

        Nice numbers.. What boost is the kit at with the 92mm pulley? 93octane??

        Thats AWESOME!
        thank you for getting on there!

        How does it perform?

        The 92MM pulley isn't the biggest up in boost for me since we are so close to Sea level at only about 500 feet or so on average

        600 kit is normally 6 psi and the 92 would be around 7-7.5 psi

        Until I move to the larger injectors and 625 tune the car will still pull timing a bit and not let it go all out. I'm a very small step up from a normal VT2 nothing huge

        This is all done on 93 octane

        Numbers are spot on what they should be IMO. Nice write up and sick pics; thanks for sharing!

        ESS does not believe in meth.

        It is pulling timing to protect the motor as it should be.

        I would like to see a boost readout because honestly I'm thinking it is more than 7.5 psi. Hopefully you can get on a dynojet sometime in the future.

        Great work IND. Like all other cars I have seen you do, this one is also incredible!

        You have to love safety features in stock DME's (i.e. pulling timing).


        Anyways, 503whp on a mustang is nice. Any speedo vids or 60-130 times?
