no mods just true blueprint, extreme balance and good parts put together well... after the boats running well up the rev limiter and maybe mod the map for a little more... maybe 10-20 hp... the hp numbers were still climbing stong and he feels 5400rpm is NO problem with his internal build

I've never had a motor built with out total balance, Thats like checking tolerances, you just do it.

You there to watch? I don't know why, but watching a big hp motor on a dyno gives me goose bumps. Especially when the guy says "That one rattled the windows"
