Tuthill 911k
Just how do you get 11,000 rpm out of a flat 6?

On their YouTube video ‘It's our new road car build. Called the 911K because its rev limit is 11,000rpm... More specs and information to come when it launches officially on Friday 19th August 2022’

Re: Tuthill 911k
They all will rev to 11,000 once ! It’s the time after that that’s the problem

Re: Tuthill 911k
Can you imagine the nerves on the dyno while winding it up to those rpm?
Would love to see the dyno sheet.

Would love to see the dyno sheet, but hope it is true and reliable.

Re: Tuthill 911k
What is the issue with flat 6 reving high? I thought the harmonics where better than a straight line or v? I understood the flat 4 can't rev over 8k because of 3 crank securing points and push rods. Apart from the largest stress on the rod and crank what stops the overhead flat 6?

Re: Tuthill 911k
Big fat heavy valves unless that engine has 4 valves/cylinder I would think would limit things, but who knows!

- Carbon fibre body panels
- Carbon disc brakes

When they say Lightweight it certainly is.
Who's going to ask the price?

Re: Tuthill 911k
What's the extra stick? Fly-off handbrake?

Looks like a hydraulic handbrake as it has a little master cylinder at the bottom.gridgway wrote:What's the extra stick? Fly-off handbrake?

That's an odd thing to have!
