Default Will standard prop take 400-500Bhp???

Can the UJ's on a standard cossie prop take 400 to 500Bhp?

For anyone with 400+ Bhp did you need to have a custom prop made for that power with uprated UJ's???

I have tried searching as I know there are a number of people with more than 400bhp and yet I can find no mention of cars having to have custom props.

Thanks guys.

I'll get the prop made with a stock diff flange and UJ then.

I should add that the reason I'm going custom is due to the length at 700mm and the front yoke required to match the trans.

And my question came about due to contacting a large number of prop manufacturers and some of them saying that the standard diff flange UJ wouldn't take the power/torque.

Cheers
