I would like to see a tuned 4.4 l turbo motor. Curious as to how much gains can be had with piggy back and flash tunes alone. 4.0 liter NA is somewhat limited unless you increase bore and stroke and add physical turbos.

We don't have HP/TQ figures to provide for these two builds in particular, because we're offering a forced induction capable build, but the actual turbo/SC application choice is left open to the owner.

Y’all are crazy IMO.

A $50-60k track build on top of a $30k M3 makes no sense to me, so more power to you guys (pun intended). Unless you go widebody can you even put enough rubber on it?

Jeez, I’d just pile all that money up as down payment on a GT3 stickshift, and happily drive that for 4-5 years...

Sorry, S54 for life!

I think you might be overthinking it. IMO, the throttle actuator movement is mostly related to the synchronization between engine and dyno governing.

Having disassembled around 80% of the mss60 and mss65 binaries, I doubt it.

And CarBahn can correct me if I'm wrong, but I've never seen a Superflow SF-902 with a feedback loop between the brake and the the throttle control and I doubt if the SF-Powermark used in the video does either. The brake is set to allow a ramp run or steady state load and full throttle pedal is applied for a ramp run to occur.

Carbahn, Any way you can share some of these technical specifications of your engines? thanks!

3) Any o-rings needed?
4) What tuning capabilities are provided with the engine (if any), software...etc?
5) Piston speed comparison for the stock vs different derivatives of the engines.
6) How much boost is considered safe for each build?
7) Warranty?

I looked thru the website, but couldn't find this information, so if I missed something, pls reference it.

Thanks for the info!

Given they have the experience to work with Alusil properly, the same as a new engine from BMW.

Given they also probably know how to set a bearing clearance properly, probably double service life of a new S65 from the factory.
How about much better then factory.

Strength built for the long-hall.

Less torque than what? A stock car - no. A supercharged car - yes.

The s65 is a glorious motor out of the box and stroker s65 only strengthen the merits Bmw prioritized while designing the motor.

What’s not to get?

If you want a durable performing superchared car, the engine should be prepped for boost.

A car that is being sold with the blower removed, is sold as buyer beware. Nobody wants an S65 that’s been beaten to death and this is very rarely disclosed.

Fiscally, sure. Buy a used car, buy a usd blower. Slap it on and have fun, I get it.

Wonder what the DCT can spin up to. I saw a Zed-F video that says 9000 RPM.

I know...just get a manual but I love the DCT!
