    Another N54 twin turbo upgrade, new option from EPD Motorsports - EPDms V2 offers 500+ whp at 1.28 BAR

    EPD Motorsports is new to the BoostAddict network but they recently showed some awesome results with their turbo upgrade on the Mercedes-AMG M133 engine platform. They also have turbocharger upgrades for other platforms including the BMW N54 motor.

    So what can we tell you about this turbo upgrade? Not much. EPD Motorsports has not told BimmerBoost much about it. We are waiting for pricing information and the full specs as well as a dyno of course.

    For now all we know this is yet another N54 option in a market becoming crowded which is only a good thing for consumers. If the pricing is competitive and it produces over 500 wheel horsepower at 18+ psi it will certainly have its place.

    All these N54 options "almost" makes me wish my stock ones needed replacement. Not only will this be good for pricing but I think eventually it will ensure vendors offerings are very reliable as well.

    Doubtful. Trying to get a graph and pricing.

    lol, what part don't people understand that the world doesn't evolve around E85. There are evos out here making 600whp on pump gas and people without E85 want a different answer besides, Oh switch to a different platform if you want decent numbers on pump.

    I think you mean REvolve. The n54 does revolve around E85.
    Also, developers are not going to put their motors at risk pushing pump fuel.
    We are the Borg. You will be assimilated. Resistance is futile.

    I don't think you'll see 500 HP with those turbos. I am having a hard time hitting 450 HP (on VD) using VTT's Stage 1 with billet wheels on E70 and water meth on 21 PSI. The EPD turbos look to be similar to Stage 1's on the exhaust side, I'm not sure about the compressor wheel size.

    Let's see if we can get a dyno and specs. Usually EPD responds quickly not sure what's up. Probably due to the weekend.

    To me, it seems the solution to making more power on 93 is dropping the compression. Ours is 10.2:1(?) my buddy with a 2012 wrx is aiming to make around 600+ on 93 and his cr is 8.5:1. Dropping compression will come at the cost of slower spool, and the whole power band will shift to the right.

    500whp is very do-able on pump gas. Just get the best inlets and Super RB's or Vargas stage 2+ turbos. Especially if your running meth too.

    You could do 600whp on 93 but then your pistons would melt
    C'mon dyno glory run for the forum

    Opps! that was a typo, I did mean revolve. Not everyone is looking for a glory run tune but more to see what should be expected on pump.

    You would need someone to create brand new heads, different pistons or a combination to drop compression that much. I remember reading somewhere that due to direct fuel injection we are able to run higher compression without the risk of detonation.

    I'm not saying for us to have an 8.5:1 cr as well; just as a comparison. That would be an interesting read, I'll check it out.

    That's correct. The effective octane of directly injected fuel is far higher.

    Would be a good idea to work out the effective compression when boost is factored in because it'll be higher still than 10 or whatever it is on 0 boost.
    Best:11.79@119mph on stock turbos.
    11.74@129 on GCs.

    Found a calculator
    At 20, 30 PSI:

    You are running 20 PSI of boost at an altitude of 0 feet. Your motor's static compression is 10.2 :1. At this boost level and altitude your effective compression ratio is 24.08 :1,


    You are running 30 PSI of boost at an altitude of 0 feet. Your motor's static compression is 10.2 :1. At this boost level and altitude your effective compression ratio is 31.02 :1
    Best:11.79@119mph on stock turbos.
    11.74@129 on GCs.
