Default HP Loss

After getting engine dyno done, does anyone know how much is lost at the rear wheels? Thanks

What transmission are you running. A turbo 400 is a pig. It robs lots of HP.

I used to have a listing of what the transmissions took up on average. I remember the powerglide was the least, but ya give up a lot of gear ratios when you go that route

I've got a TH400 with a shift kit. Just kinda want an approximation, doesn't have to be exact numbers. Just kinda want some what of an idea about the loss.

With a TH400 you're looking at about 25% loss between engine dyno and rear wheel.

From personal experience; Mine dynoed 628 hp @ flywheel, and 490 hp rear wheel. That would be a 22% loss.

W/ TH400 trans and 2900 rpm converter.
