Well this (for me lol) has to be the coolest engine re-design from old to new-ish I've done in a while, yes it,s a race engine but with the low port timings will have a large-ish power band from around 6k to peak @ 10500.
The main area has been the exhaust port, remodeling the guff over sized single exhaust duct to a more modern triple exhaust and the first RD400 to use a nozzle

Wow, awesome work!

This must be the most exciting thing to happen to aircooled rd400's in a long time!!
Where do we place orders?

It will be very exciting once tested on the track........this thing should be super quick and a good place to improve over time!
