Default 1000hp IS300 with stock IS F Transmission


I came across this video in my social media app. I found it interesting the owner is utilizing the IS F transmission in stock form. How is it that it’s holding up to such amount power?

RR experienced the valve body opening at around 700 whp (plus or minus), so I’m real curious. I doubt it’s 100% stock.

Reading through the comments the tuner increased clutch clamping force to hold the power.

Does that mean he figured out how to tune the trans?

I hope it's tuned. Then maybe we could get a good converter too.

Exactly. I was talking to a supercharged IS F owner. He actually ended up having to replace his transmission. He said the old one started to slip after approx 600whp.

Transmissions don't care about HP. They only care about torque, and they're spec'd by torque. The way turbo engines make power, it's very possible it's making 1000 hp with similar torque to the 2UR and a significantly higher rpm.

Kinda like this guys sounds good, I drive my CLA45 AMG time to time and people say these cars sound bad but the CLA45 don't and I only think that because of the dsg shifting and the crackle nearly sounds identical if you listen close to both of the cars... both 200t/300 & CLA45
