Diesel crank... worth it?

lightening the crank is a waste of time, money and effort!!!

Its inertia that you want to minimise and since the flywheel is a big source of this and its cheaper and easy to lighten a flywheel why not just do that?

FWIW the td cranks have lived their entire lives @ ~20:1 compression whereas the eta cranks have been babied @ 9:1 compression. If tuners used td cranks for their strokers, I would guess they were going with new hardware. My .02 is that an eta crank is better if you are going with a used one.

but TD cranks are designed to take 17-20:1 the Eta aren't designed for >6500rpm.

yeah I have been thing about that alot since I posted before. I think just balancing for the crank and run a really light fly.

188.8rwhp and 181.5rw lbft. I am running 10.2:1 compression so it may vary depending on set up.

Can you tell me what pistons you are running to get this C/R? Also did you deck the block and if so by how much?

neither is the TD crank
