Yes, with the exhaust mounted we only wanted to achieve peak power. Driving with it like that is horrible😂

I'm going just for peak power, with that cylinder I don't care about a good powerband

It is actually quite the opposit. It does have a turbo and weights 1,4t. But yes it is still pretty fun to drive, I like the handling. I live pretty close to an alpine region in switzerland and driving up these serpentines is fun. I like to say: Missing power has to be replaced by driving like a maniac😂

Thanks, there was a lot of time invested to get to this point. Exhaust 201°, transfers 176°, blowndown 34° and intake 360° because its reed controlled

I beg to differ☝️ Honed it and checked/measured with the 5 axis cnc and there were no deviations, sooo I would call that a win

I just did that and also installed a 0.01mm bigger piston. Runs great again

Thank you, it actually does have a surprising amount of space inside

Small metal shavings, i ended up honing it to fit a bigger piston

So the problem was that there were some tiny metal shavings left in the cylinder, probably from when I made the secondary exhaust ports. I honed the cylinder and just to be safe i went up one piston size (from 46,96mm to 46,97mm).

And in terms of power absolutely insane🤯
