No, no… Not WHP LoL..
On paper, it should be at about 440 hp - 460 hp at the flywheel.
Last I checked my boost gauge I was pushing 11lbs, with a couple of minor boost leaks. It supposed be 11 - 12 lbs anyway. So with a baseline hp of 230 hp for my M54B30, plus 12 lbs of boost (leaks have been fixed) which equals 168 hp (12 lbs boost X 14 flywheel hp per lb of boost = 168) my supercharged baseline hp is 398 flywheel hp.
Now the headers increased the power substantially initially. But, now that the system has adapted to them, I have noticed a solid power increase. So I feel it’s safe to say that they added more than say 5 or 10hp. Remember this setup is FI, so power is generally doubled, sometimes tripled with the addition of certain parts (down pipes, etc). I’ve seen a good down pipe add 60hp on some setups.
Now the ethanol is a whole different story. Last I checked I was running 81% ethanol, 19% gasoline. This fuel has completely changed the dynamics of how this setup functions. It increased the torque substantially. And, it runs the top end to redline without hesitation (top end was pulling a bit of timing on pure gasoline). So now the power is solid from 1000 to 7000 rpm. Zero issues now.
I am no longer injecting meth. Now I am injecting 80% pure ethanol, mixed with 20% distilled water (it is still flammable by the way). This is done progressively by pedal position, rpm’s, and follows the fuel injector pulse. As the pedal and engine speed increase, the more ethanol/water mixture is injected. I can run my X without this system activated, with zero knock due to the high % ethanol fuel I am running. When the system is activated, it adds more fuel making more power (the small amount of water is to cool the boost, water absorbs heat). This also allows more boost (12 lbs in my opinion is the limit for a stock M54 if you want it to last). This system is no longer used as a knock suppressor. It is used as an additional fuel source. More fuel more power. But, only if your setup is tuned for it. Mine is..
So with my blown baseline being 398 hp, I am pretty sure the headers, ethanol fuel, and additional ethanol injection is capable of producing another 100 hp. But for me, 40 - 60 hp is good for me. Maybe one day I’ll strap her up LoL.. But, the times I’ve had so far with M3’s, M5’s, Mustangs, etc. new and old, a dyno run for me personally is pretty pointless.
A M62TUB46 has 340 hp. So with 6 lbs of boost, the baseline would be about 424 flywheel hp with a proper tune, without headers. An ethanol fuel conversion (not a tune) should give 30 - 50 additional hp. Meth injection would not be applicable here. So in my opinion a 4.6 would put out about 464 flywheel hp. Not bad..!
You definitely need to buy Nick’s conversion! LoL.. There are only three manual AWD E53’s that have over 300 hp in existence to my knowledge. The X5LM (6.0 700 hp), Nick’s (4.6 340 hp), and OLe’GiRL (3.0 460 hp).
