The guy with Lotus missed a few shifts here and there. Pinned at rev limiter for 150~200 meters or so. Could be a different story with another driver that shifts better.

I want a used GT R. As in now!

That is incorrect. The part number is 11247624615, the same as all n55 engines. You can run the part number if you dont believe me. The rods are the same, they have to be since the cranks are dimensionally the same and the s55/n55/n54 all share the same stroke and comp ratios. The rods between the n54 and n55/s55 are identical except there is an extra machining operation on the wrist pin whole to create a more distributed load when the wrist pin slightly bends in the elastic region. This is all from the bmw technical documents. All the turbo 4 and 6 rods are forged steel fracture split rods.

$1.5M and no SatNAV? Pfffffffft

The E63 looks better and sounds better, but it seems clear the M5 is the better car...faster, handles better, better cohesion between the various chassis components. The Comp package is not just stiffer springs and an ECU tune, as so many seem to mistakenly think (despite the fact that it’s quite easy to go see what it’s comprised of) - you get different springs & dampers that are obviously factory units that integrate with every other system in the car, that means new programming for the suspension, as well as the DSC, the diff, the steering, the engine, and all the rest. It all works together. You also obviously get other new components in the suspension and steering that can’t possibly be replicated in the aftermarket, and yes you get a nice bump in power and louder exhaust as well. Plus lighter wheels. Very much worth it. Many people track their M5s, and frankly who gives a shit if they don’t - it’s not designed to be a track car, it’s designed to be enjoyable to drive on twisty country roads and the like. Those changes will be easily felt on the road as well. Just wish it sounded better and looked more dramatic...also, really think the E63 has the better gearbox. I suppose if one is going to add a few hundred hp on top of the stock power output anyway, it might not matter as much. Even given that I’m a BMW guy and that the M5 seems to be superior, it’s hard to pass up the seductive drama & sex appeal of the E63.

That menu comes in the previous F generation as well, normally the the car switches over to Dyno/Roller mode once it sees differential speeds between the front and rear wheels. Now on the F90/Gxx, you need to be on Diagnostic Mode prior you start the dyno runs, you access Diagnostic Mode by pressing start button 3 consecutive times without stepping on the brake pedal. Linked Dyno usually is a straight shot, runs on 2WD mode while only using a single axle dyno its when all the steps and conditions need to be in place, otherwise making a clean pull without interventions form the ECU gets very difficult. As far as Power output not too sure about Roller mode or even 2WD vs 4WD make a difference at all... I have seen 20hp between settings, but when comes down to Turbo cars, your runs will variate that much or even more, by just letting the car cool down or back to back pulls.... Just my two cents.

Can't wait to see the press cars that weigh 1,200lbs and run a low 6@200mph.

Let's be honest, it better have excellent performance as it doesn't look good under the hood. I love engineering, but you can tell its three cores sandwiched together with welded plates on the outside. Not clowning anyone, but it reminds me of some old DSM parts, a couple of buddies, beer, and welder in the winter time.

Curious to see what the difference in weight. Depending on what materials used it could already be significantly heavier than OEM then throw in fluids..

price?

Cool - I say the complete opposite F90 has everything nicer and better. To each their own.
