This is correct

It's a beefed up version of ZF 8HP. Check out Pure Drivetrain Solutions.

The question is if this car can run up to 50k before the engine/gearbox/differential blow up!
Is this ZF8 rated to that power?
Beside the straight line, is this car able to run over the corners? I mean is this suspension designed for this power?
Anyways good job 👍
We're not sure about the limits of the transmission because we had it built while we sent the DME to Russia and did some paint protection work.

The G8x is really nimble and the power doesn't really change much in that regard.

And thanks!

Extremely light mod list minus the built trans. These times are very impressive!

I had a FBO F80 running full E85 via a Fuel-It! port injection kit and a custom tune by the legendary Cary, but all the power felt a bit lifeless and numb because of the DCT. I have never driven a high horsepower manual.. wonder how the G80 would feel with all this power and a manual 🤔
I've owned and raced several high HP manual transmission cars in the past. (Not BMWs)

I'm guessing with a good driver a built manual trans setup would run 10.20-10.30s at similar mph with that power.

48 psi - abs 14.7 == 33.3 psi which is correct.

Was confirmed by OP some replies above.

I think you are right, guys from NV Motorsport UK are pushing 1.7 bar on their M3, which is 24 ~ 25 psi. They got around 650 whp.

Were pulling the engine on the g80 monday.

Building it with the following mods below.

Forged rods/pistons
Fire rings
Head studs
CNC heads
Billet intake manifold
Port injection meth/nitrous/fuel
3d printed full frame turbos
CNC rear spindles
Brake conversion
15" weld wheels with radials
Carbon fiber front wheels
Carbon ceramic brake conversion
Carbon bucket seats

Everything is being designed or made by us. The CNC heads are being done by our friends at Frankenstein Engine Dynamics here in texas. Turbo CHRA used will be garrett, have not decided on size yet. Everything else is being made in house.

Were installing our dyno here in a week or two and hopefully have the car back on the road in 3-4 weeks.

Thanks

Impressive is an understatement
Built transmission is a little bit of a stretch. That's a tweaked transmission which is incredible
Whom ever is the tuner , if that motor last 20-30k miles , you my friend are either a genius or BMW is sending off the final ICE cars with engines that will out live us, I have seen some shit, but 2.45 and 9 sec out of a few bolt ons, lmao Tesla Plaid .
If Elon makes a model 3 (yes It's called a model 3 not an M3 you lazy Tesla owners (I also own a Tesla ))do what the plaid does then compare these 2 cars.
What a monster this makes me want to sell my m5 for an m3.
I can almost buy an M5 and An m3 for the plaid
The difference

When you turn on the M cars, they return the favor.
