They ran an 8.5 shortly after, the M5CS is in Russia, done by a tunning/fabrication company (LEVEL). I believe its still running on stock internals, bigger turbos, meth, fabricated intake/exhaust manifolds, all the piping, upgraded fuel system, ecus and tuning.
The car was test a car, but they essentially have a package that customers can buy, they charge over 100k USD or 13-15millions Rubles, so do the math to make your M5 CS run 9s. The "street" tune is 900hp at the wheels, you can see in the video during city driving, punching the gas pedal makes the rear kick out like a RWD would. Going straight. Some interesting things to note: The cooling in the vehicle is stock (radiator, oil coolers), in fact they praise the engineering of it, they said no aftermarket cooling solutions exist that do it better than OEM, in fact they use S63's radiators/coolers when tuning other cars. Just remember they tuned this car to run 1/4 miles not track days at 95F at Thermal, California. They were able to get the car to run sub 9.5 on stock turbos. Transmission is holding up, but they expect a full rebuild, as in the current state with how many launches (dozens) they expect 20-30K km, i think that's too optimistic, but essentially maybe 10k miles before it starts slipping. Everything else in the drivetrain is still stock. There is a dual counter in regards to launches, there is a launch counter and "hard shift" counter, they had to reset both. The car's keeps an eye on a lot of things when driven hard, mentioned something about high angle too. Now to get to the mid 8s and have a world record, they went for broke. They increased the boost essentially for the car to make 1200hp+ and it was either going to blow the engine, or get them a record. Which they did at 8.8, and did the 8.5 a few days later. On draggy it ran a 1.80s 0-100km. The records were set on race slicks on prepped surface, after many attempts. Another tuning company also in Russia is in second place 8.7 on a "regular" M5C. Fastest M5CS and F90 in the world. |

If it really is a stock block, I am impressed. Perfect timing and consistent high octane fuel reduces the chance for detonation that bends rods but everything I have read is that the rods simply are not strong enough for 800 lbs rwtq.

Anyone think the Russian claim is bs? The car in the video I posted here is a modded M5 with 1000 hp and did the 1/4 mile in 10.0 seconds. Seems a bit dubious the Russian modded car is getting a sub-9 second 1/4 mile. Just curious on the thoughts on this. |

And once again they ran it on special slicks on a prepped surface, with 1200hp at the wheels and its a lighter CS model. Carwow's M5 is on street tires, on street tune, and its 1000hp at the crank on crappy old airfield asphalt. I like carwow but its apples and oranges. |

Russians love fast Germans. Men's motors, 7force, hpc, and a bunch of other shops are have been building some wild stuff for a while. Link above is the fastest m8 comp in the world vs tesla model s plaid, includes 1/4 mile pass on a track. |

I'm might be wrong but I don't think build internals is a very common things for the F90. There was a youtube video about a US auto metal shop, that fabricated forged/robust rods and pistons. It seemed to be the only shop in the US that did that, they also had to do a lot of trials and testing to make sure everything was balanced and had the same level of mechanical performance that an oem part would. So it would makes sense their internals are stock, because either they don't have a good solution for aftermarket rods/piston in that part of the world, or they don't have the capability and/or resources to fabricate and test their own. That would be its own beast on top of all work they did with that car. And lastly I had a buddy, another M5 owner tell me that the part number for the rods is identical for the S63 and S58 platforms. And there is a lot of tuned S58s and B58s that allegedly don't bend rods, while the M5 does. I find it strange since it makes sense that some internal parts would be similar across the line up, but I'm no engineer. I'm sure in the V8 there is a reason it breaks easily compared the 6cyl engines. I don't why they don't just beef up the internals, like the AMG did with the fully forged V8, the trans can handle it. |

The 3.0L of the S58 won’t spool turbos as quickly as the 4.4L of the S63 — you read of lag with the S58 but not the S63. It is that sudden, early torque that is hardest on rods and that also creates the greatest opportunity for detonation. Careful tuning in the S63 to limit boost at lower rpm can help extend the life of the rods on modded motors.
Aftermarket rods and pistons are made by several companies. And there are a number of shops building the S63 in Europe and the USA; some change only the gods and some change both pistons and rods, depending on power goals. Not cheap at $15-25k just for the built long block and $5000 more to install it. Add bigger turbos, intercoolers, supersprint exhaust manifold, upgraded intake manifolds, cams to drive the fuel pump faster for E85, and you can easily double that. Building a motor was not holding these guys back. I suspect they will blow up their current motor and build a stronger one. |

These are not simple motors. The cheapest built motor I would consider is $15k from RK. Ghassan is cheaper but too many bad reviews. Carbahn stage 2 build is $25k.

Cheapest option on the market is to use the arrow drop in rods. $3500 as of today. Then add in labor, bearings, fluid, etc.

And what do you think labor is to remove the motor, disassemble the motor, reassemble the motor with the new rods and reinstall the motor? Evolve charges about $20k turnkey as I recall.

I would assume this is why the B58 and DAZA platforms are so popular is you can make the cars just as fast for half the price including better internals. This instant torque at low rpms or when there is "bogging down of the motor" situation is what scares me doing a simple tune. Isn't there a thread on here of someone bending rods like that on just some downpipe and a tune? Do you think the S68 will be a better platform, more robust to be in a 800/900 tq range? These TT V8s are easy to make power with, but I'd like to have longevity. |
