2.2 crank

[hcrubg]

can you balance a 2.2 t crankshaft?

Depends what you mean. Why do you ask?

Spin balance, sure. But most 911 cranks are very good from the factory.

Do you have a T crank or an E or S crank?

Thought he said T crank which is the only non counterweighted 66mm one from that year. In spite of not having counterweights zI would think any good crank shop like Marine or CCR could balance with their machines. If it were me I’d contact Marine Crank to get that done.

always heard never use a t crankshaft because it is not counterweighted
seems like a good shop could do it
did porsche not do it because of cost, or what?

Cost and no expectation of higher RPMs.

Sounds like we may be mixing the terms balanced and counterweighted. A non-counterweighted crank is balanced (or at least it is as far as I know). Making it counterweighted, while technically possible by welding on counterweights, probably wouldn't make sense to do.

No, it's *always* use a t crank because it's not counterweighted. Spins up even faster than a lightweight flywheel.

No good for sustained high revs though, i.e. over 6,500.

I always balance the complete rotating assembly, I even recommend it on stock engines.
