It is a very nice car but there is more to an M5 than a tune.

Cool.....Just about a 10% loss on DynoJet...560 CHP Vs 525 RWHP not bad...so that puts the 550i at 10% gain over a 430 RWHP roughly 483 CHP still not bad in comparison to 560 CHP but not close enough...I get it...sorry guys

Stock. You're torque numbers are close actually.

These are whp. 18% drivetrain loss puts it at 640 crank.

BTW...We were only able to Dyno in Normal mode....the car would revert to limp mode when the Sport Plus was selected (two wheel dyno)...There may be more HP gains if we were able to dyno in Sport Plus....Either way its all good...

I believe it's more than 10% loss.The general understanding seems to be that the M5 is underrated by 40-80hp... (525WHP and 15-18% transmission loss = 600-640CHP).

This would indicate that your 550i is at around 500+CHP. Not too bad

Thank you Boss....I am enjoying the torque and the way the car pulls.

I cannot ask for more. It is a gentlemans car, subtle with great potentials.

Good Numbers. I am sure that the 550i R&D is far from over.

Am I mistaken or did the OP jump on here with a 550i with some quad exhausts and a tune trying to say he has frankensteined a bargain M5? LOL That is just hilarious. Made my morning.

Here is a great example of how even with a huge visual representation of big dyno graphs of each car, people don't seem to get you can tune, tune and more tune the 550i all day long but it (as well as the N54, n55 engines) suffer from a huge torque spike and than dropping off the face of the early and the power absolutely coming to a hault like hitting a brick wall at 5500-6k and above.

The M5s power delivery is shockingly similar to the S65 power curve only shifted to the left by 1200 RPMS. A real atypical turbo car curve and more like a nice flat torque NA V8. Check out an m3 dyno to see how similarly shaped with the complete linear curve.

All that to say you could tune the piss out of the 550i but you will still have a mound of torque and than hit a brick wall at 5500-6k when pulling hard and that is not a character of an M car in my view. BMW saved their soul in one respect by atleast providing a turbo car that produces power in the same fashion as a big NA V8. Quite impressive

Not really. I didn't take it that way. He was just showing his numbers. He's cool in my book.

Thanks Urban Legend...Exactly my point...Incidentally, I do own a 2008 E92 M3 with a VF Engineering 650HP Kit that is pulling close to 590WHP. I have nothing to prove.......It was fun sharing with the M5 section....See you guys around campus.

I loved my 08 550. It was fast, fun, and looked great also. Congrats on your numbers flyboy.

The car says 550i on the back still, and the exhaust looks clean - I've no issues

Congrats on your numbers... If nothing else you reinforce the differences between the two, but you are showing how all BMWs current lineup has room to produce more from stock.

Cheers

Cool? This is the M5 section, not really sure why anyone would care? If we wanted 550's we would have purchased those
