103 Octane, catted down pipe with stock exhaust - 550 WHP and 417 WQ!!!

These numbers were recorded using a Dynojet 224x. Here is the dyno file:



The following graph shows the same exact dyno runs on our Superflow Autodyn30 recorded the same day. We see numbers 6-7% lower than any dyno jet. (This is pump catless and 103 catted)




Benefits when comparing to our competitors:
  • Stock MSS54 ECU tuning

  • All factory diagnostic checks are functional
  • The catted version will be able to pass all OBDII readiness tests without any "trickery"
  • OEM int
  • The catless version will have no CEL illuminated, however it will not pass the OBDII readiness test for cats and 02 sensors.
  • Our kit produces more power across the entire power band pre pound of boost when compered to any other bolt on turbo or supercharger kit without methanol injection
  • A cheaper more powerful turbo option
  • Our kit utilizes a tubular stainless steel manifold
  • Hand fabricated parts made and quality tested in the good ole' USA
  • The power gains we show are made with the bolt on kit through a full stock exhaust; nothing else is required to reach these numbers!
  • More gains are to be had with additional exhaust modification


Dyno Comparisons:

Maximum PSI Pump
Catless through stock exhaust

VS.

ESS VT2-550
Euro Headers
Highflow Cats

Looks like a very impressive kit...had this been out a few years ago I know the decision would've been very clear. Excited to drive one of these in the future.

We compared the 6266 and 6766 and chose to stick with the 62. We have a built motor car getting the 6466.

What about stage 2 or 3? How much power can the stock ECU handle? Or should I say how big injectors can it run? I'm sure everyone is wondering about upgrading and price for let's say to make 700 rwhp,would the stock ECU handle it or would the customer be required to buy standalone?


I'm sorry if its been answered already,haven't been on here lately,


Thanks!!

I think going up to 700rwhp on a kit like this takes away from the whole point of the kit. Simplicity and drive-ability. Obviously the HPF cars for the most part drive like stock, when I say drive-ability I mean, no check engine lights, no massive 4" exhaust, etc.. just a real well put together kit. You start getting into stand-alone territory and the prices are going to jump up real fast.. wiring harnesses, the ecu, etc, etc.. now you're looking at the same price as the HPF Turbo kit.

I made 750 whp with my E36 on a stock ecu with NickG behind the keyboard and mike making the hardware. I used to daily drive the car with the same benefits of a 500whp car...then I got speed hungry and gutted it.

We have a current built motor kit e46 that will test the limits of the 6466 utilizing the stock ecu.

Our name is MAXIMUM psi

That is true....but Nick G did his magic on E36 cars and you could drive 650rwhp E36 M3 and had same driveablity like the 400rwhp one just a lot faster,but I wasn't sure about E46 ECU since active tried it and it didn't work...

Supporting 700rwhp should be no problem for the factory ECU.

Another reason to sell my E39 M5 and look for a E46 M3.

My Ride: 2006 M3 Coupe 6MT
I'm excited to see this product come to market!
What a great combo; high quality hardware via Mike and team, plus the best in the land at tuning, and noteably in the turbo-charged arena, NickG.

Even though I have a centri-kit now; I'm mighty tempted . . .

Does anyone have pics of the underbody with the current kit configuration?
I'd like to see how much, if any, of the piping is below stock underbody clearance.
