.020/.010 cranks??

[FastGN007]

What is wrong with turning a turbo crank .020 on the rods and .010 on the mains? Has anyone ever used a crank turned .020 on the rods? Any information or opinions is appreciated.

I have used them and it's ok

The problem is that there is not much meat on the rod journals.Many have done it,probably be fine for 500 engine hp.

I got one for sale. I will make you a good deal on it. It's standard right now.

Let me know..

.020 under on the rod journals should be no problem...All the strength in that journal is in the pressure rolled fillets in the corners...The .020 smaller diameter is not going to weaken the journal any...If the crank is going to break, it will break in the corner, where the pressure rolled fillet is, not in the middle of the journal...Since the diameter of the rolled fillet doesn't change, the strength of the crank shouldn't be affected...

Just have the crank crack checked...You will be okay...
