    Be interesting to see what power they make and if they can be revved to 9.5k

    It's the top end that will be the limiting factor on if they can Rev that high, would need some pretty radical cams to make power to those revs, solid lifters too and a mega flowing head, it's not hard to make a bottom end 9500 proof

    A ported st170 head will flow enough and a call to cat cams will sort cam issue

    Re: Look at these I want

    For 9500 rpm?, hmm, you would defo need solid lifters and pretty stiff valve springs, it would be a full race cam too. I think realistically you'd be looking at an engine making power to 7700 maybe 8, all they are saying is that the components are safe to 9500.

    Do you know the spec of the engine they are going to build and what power they are looking for be interesting to see what it makes

    I'm wondering it would be so easy? A call to CatCams for the right cam and a ported head will not take the engine up to 9500 RPM and still make power. It will take a few months developing and maybe a dozen of cams.

    OK but it does not mean it can rev to 8K it's still making power at this level. Let along at 9500 RPM. But yes, it can and will run 9500RPM and even a lot more as long the gearbox is in neutral. With no rev limiter you can rev it until you only have bit's and pieces.

    The point I want to make here, if the torque curve is going down totally it has no sense to rev this high unless in a one gear speedway car. It's damn difficult to let an engine make power at 9500 RPM, specially with a long stroke engine.

    Re: Look at these I want

    Know its an old'ish thread but wondered why the - not to 9.5k revs comments arose? After all this is a derivative of BD heritage and no one questions their high rpm / power potential. While 'safe' to those revs, which is impressive in itself, power may have left the stable long since!

    I'll see if it makes any more power as the revs rise

    How refreshing not to hear "fully forged", I wonder, is that a need for speed term ? Seems to be bantered around by the children on the internet a lot.
