Crank was prepared the same as used by Mini Sevens and checked with plasti-gauge on build. I'm sure MED do not use an "it'll do" attitude for race engine components.

What RPM has the crank damped been designed for? On 15th May, 2009 TurboDave said:
I think the welsh one has it right! 1st to provide running proof of turbo twinkie in a car and first to run a 1/4 in one!! Is your data backed up?? one extra month free for all Turbo minis members, PM me for detials |

No idea, but I have the tools to work it out if I could be arsed.

I'm guessing Jimster it the expert here.. His grasser must see well over 8k? I run a supercharger and I don't care the TB is on the wrong side.

How high can you rev it? How high does your gauge go? |

No idea, but I have the tools to work it out if I could be arsed. The mass of the damper is not that critical. As long as it is in the range of 5-25% of the mass of the rotating assembly, excluding the flywheel, then it will be effective. You initially ask such a simple question in reality, when you are capeble of calculating the torsional vibration frequency of a crankshaft and mass of a suitable damper??............What's going on Paul?

Is it A-Series only? I think it should be... So when some joey comes on here about how his 16v turbo vauxhall is great compared to ours, he can be given the 'bird'... On 26th Oct, 2004 Tom Fenton said:
Yep I agree with TD........ |

Because it's about a weeks work to do the calcs. Easier to gauge from others experience. Saul Bellow - "A great deal of intelligence can be invested in ignorance when the need for illusion is deep."

I think in this situation I would be listening to the folk with the most directly comparable experience.
