    • Maximum PSI sets new stock internal E46 M3 power record with 902 horse turbo S54 dyno pull

      The S54 proves yet again what a beast it is. If you are going to call any BMW engine the German 2JZ it's the S54. The proof is in the 902 horsepower and 644 lb-ft of torque at the wheels Dynojet pull from a Maximum PSI turbocharged E46 M3 S54.


      Oh, and this is tuned on the factory ECU. Fuel is E85 ethanol and it certainly helps that there are no direct injection fuel system limitation, right? Yet another thing the S54 has in common with the 2JZ for those who keep track of those kinds of things.

      In all seriousness, congratulations to Maximum PSI. This is incredible power on the stock internals and a tremendous record. It is great to see naturally aspirated M engines show what they can do when properly boosted and tuned.

      Hats off to the best six cylinder BMW engine ever made.

        Is this with the SMG box? Very impressive numbers. The E46 is dirt cheap in Europe.

        Not sure which gearbox. They both can handle they power as they are the same basic thing.

        Whose car is it?

        If you can 902 whp I don't think I'd even bother building the engine. Just get a nice used E46 M3, this turbo setup, and be happy.

        I would assume it has to be him. Guess the tuning for the turbos has evolved pretty far.

        think 130k miles is crazy with a turbo?

        I have 226k miles with a MaxPSI turbo, stock motor & ECU running strong at 14psi.

        according to their website, it cant take a huge amount of power and be reliable. my buddy at mpact actually swapped his car over to a 6mt from an smg trans.

        Im not talking about the SMG. The actual sequential from Samsonas is what i mean.

        The Samsonas isn't a sequential transmission. It's still a 6 speed.
