M6GC CP vs E60 M5 RPI fully modded

[Fly M5]

Was down in Mexico this weekend. I was the camara car with a passenger.
Temp was 97. M5 had RPI full headers/exhaust, scoops, etc.
Both in 2nd gear roll from 60mph.

I think that's about right; full blown mods and a rolling race would be the stronger avenue for the E60 S85 car. Nice vid man.

thanks P'Tom, wish we couldve made it out =(

[RPiM5]

Yup, I've also seen an RPi Stage 2 E60 M5 beat a Panamera Turbo S from a 60mph roll too.

Stage 2 RPi M5:

Curb Weight ~3,900lbs
Horsepower ~ 580-600hp
Torque ~ 450tq

Stock M6 Gran Coupe:

Curb weight ~4,400lbs
Horsepower ~ 600-640hp
Torque ~ 560tq

All values to the crank.

Weight makes a difference and the M6 is trying to beat a car that is about 500lbs lighter with only about 20-40 more horsepower.

What mods does the m6 have to make 640hp?

640hp is what the M6 is making stock. These F-Series M cars today are highly underrated.

I don't think they are making much more than 560. The 6 speeds are trapping 115-117mph and the DCTs are trapping 118-122mph which is about right for a 560hp car that weighs 4500lbs with driver.

Nice vid. That damn v10. Lol. Sweet! Dn now I'm gonna have to take my car out for a beating.

Actually the GC is almost 4500 pounds without the driver ! It's a sexy tank !

i like the way SMG lags and DCT gains during gear changes!

NA V10 FTW!

Yes, this is my experience. I am getting a better trap now with the Dinan tune and I think my car has about 640 up from 580 stock. I don't think I got my best run yet with the tune but now I have to get this CEL issue worked out before making anymore runs.

[Fly M5]

Keep in mind I had a 200lb passenger in the car. I ran the GC hard for 5 hour straight...it pulled and handled beautiifully. I'm very happy with the beast! BTW the GC weigh only 43lb more than F10 M5. I think if the run was 1 on 1 the GC would win. Also we started from 60 in 2nd gear which is the sweet spot for E60 M5. I believe if we would have start 30 or 40 the GC would be ahead more due to the torque. It was a great weekend running with my E60 M5 friends

Yeah you'd have pulled a little bit more and held more down low like 40... 60 is really pushing it for 2nd gear.

Well my car dynoed at 549WHP bone stock. I don't think the drivetrain loss is 2% lol. Even with an 11% super efficient drivetrain, you are at roughly 610hp. I think 640crank hp is a bit high but not for a Comp package car.

Agreed. Better off being in your torque band in 3rd gear at 60 where torque is climbing not dropping. A high revving v10 should max out revs but not so much in a turbo car.

I ran a FBO e60 M5 with custom intake/eXHAUST and doing a 40roll put a stock m5 out by a half a car or so until limiter then he pulled

Maybe your dyno op has been taking too many happy pills... Think about it, why would bmw underrate their m divisions power, especially with the hp wars going on in the segment.

Most of the stock F10 Dynojet dynos out there have been 530+whp... either these dyno operators are either taking happy pills or maybe just maybe the HP rating is low.

[gmd2003]

The main problem for the GC in this race was the extra passenger, it def does not need another 200 lbs. Put the passenger in the E60 M5 and watch how bad it loses.

I'm not taking positions on the underpowered/overpowered debate, but the answer to your question is below. There are more reasons, but these are the main two:

1) Keep insurance premiums low(er). This is a fact, so please do not rebuke with the "If they can afford an M, they can afford the higher insurance" thesis. Not everyone driving a new or used M is a 1%'er bathing in money.

2) Liability issues. High horsepower rockets are headaches for automobile legal teams. In tort-euphoric, uber-frivleous legal systems, ANY protection from blood-sucking plaintiffs is welcomed. Remember when Paul Walker's camp tried to sue Porsche for fault? Though that lawsuit was quickly dismissed (i believe), the preceding example is a macrocosm for the legal climate for automobile manufacturers: OEM's need to protect themselves by any means necessary, for they are huge targets. Lowering stated horsepower a few percentage points may be nonsensical to a consumer, but in a global business landscape dicated by analytics, actuaries, and profit, NOTHING, not one choice or decision, is done whimsically. It's all tactical business decision-making by the smartest minds in the indsutry... If they can lower 'bark", but keep the 'bite', then they killed two birds with one stone. OK, enough of the euphemisms...

You sir are correct. So then we are looking at 4,700lbs versus 3,900lbs. Lol!

What about the legal implications about lying, does that not mean anything any longer? I would think being honest about the numbers is the way to go and the customer would be making an informed decision.

I know about the insurance premiums, it might have been the case with the n54 and n55..... Maybe. I just don't see it as an insurance issue and I do not see insurance as a factor , especially considering these are 100k plus cars a slight % change in premiums won't make a diff. They are already forecasting a 600hp m5 next year and have a 575hp cp now. Losing track and getting carried away with outlandish theories only exacerbates the conspiracy some attempt to create.

I would hate to see what happens when the 707hp hellcat at 65k hits the road, I guess they were trying to keep insurance premiums low there too! Didn't they step all over hp numbers of the viper too.... Hmmm lots of genius decision making there. But just maybe they put that number there cause it's accurate, ya think.

I'm gonna let this one go, I believe the numbers are mostly accurate, but I may be wrong and my legal experience with such a large animal errs more towards being accurate than not.
