RK Tunes 670whp G80 M3!

TopJimmy · 04-21-2021, 12:55 PM

The motor is helping me get over the face, a little.

EndBosS · 04-21-2021, 01:09 PM

670 WHP

If he has 650 Crank, I might believe it, no way this car is making over 700+ crank x)

GOLFFRR · 04-21-2021, 01:10 PM

unreal. wow

TruthOne · 04-21-2021, 01:19 PM

When he first got this car the first thing he did after leaving the dealership was abuse the hell out the car. I know he's a tuner but he seems reckless to me

Maybe if the potential owner/lessee is going to track the car. Then the performance can overwhelm the face. But otherwise, No.

True that. That's just sketchy

Need an S58 built before June 2020 for flash tuning. Like the one in the X3M

MisterF80M3 · 04-21-2021, 02:16 PM

Holy smokes....

I don't believe 650 crank would yield 7.06 60-130 times.

Dumb platform to drag race regardless and too heavy for real road course duty.

The car is tuned via a piggy back for the port injection as well as the JB4 from what I heard in the video. Granted I was trying to multitask at the same time, so I may be wrong...

I mean who knows really? At 670 whp and AWD, you could hit low 10s easily.

All about the Torque!!

I think he hinted at he will be giving away that very same car in his give away (makes sense to drop it while it's hot after he just beat the living piss out of it pre-break in). Good luck to the next owner!

SoCali E36 · 04-21-2021, 03:30 PM

There's going to be some really rich BMW SAs out there really soon.

There are varying philosophies on break in. This has been going on since I first came to BMW in 2001. His approach is nothing new.

It's the same as the F90 M5 right? shouldn't be any issues til 1000hp+.

Why? We have F80 running 9s. I didn't know 9 second car is a dumb platform.

There's obviously a break in with the G80/82 because the dealer requires you to return for fluid changes at 1200 miles. He was doing burn outs and going crazy on the car non stop. A few pulls is understandable but that wasn't all he was doing

XsltAnalyst · 04-21-2021, 03:58 PM

I see a huge dip in power around 4.5K rpm, how does that affect driving?

With the limited traction and a MT, this car even with all that tune this G80 will be slower in everyday driving compared to AWD G80

But I guess it's good to see people testing the limits of the new platform, and trying to get around locked ecu
