POTR Big Valve head Spec

[Debo]

You'd need specially made valve gear if you wanted to rev that high. I don't think anyone has done it with this engine, so your guess is as good as mine. Why though, would you want to rev an 8v to 10,000rpm?????

I'm unsure you know what you're doing tbh, because you should know that a head is just a piece of metal, so asking if it can rev that high is simplistic - how high an engine can rev is down to the stroke of the engine, and as far as the head goes, the weight of its valve assembly and the strength of the springs etc. How many road going engines rev that high? 10k or more is reserved for bike and F1 engines.

LIGHTER VALVE TRAIN

I was wondering if the head will support all these mods and not just explode.

You need to stick to a simple Seb set up by the sounds of it.

I think you should sell me that manifold as it doesnt sound like your going to make the most out of it

'use' is not a word in the context you are trying to use it. Speak properly or not at all.

Thanks

Standard engine goes easy to 8000rpm. What you have to do: balancing crank and flywheel and pulley.

To rev higher, like andyb said. Lighter valvetrain is the best way. Look on the followers i had for my project. 160gr. less only in the cylinderhead.

Its not a problem to rev near 10000rpm if you know what you have to do.
But to make safe, you need a lot of money only for the engine.
