Re: engine on the dyno
 

What mods did you do?I am going to do mine this winter :)

Re: engine on the dyno
 

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

Re: engine on the dyno
 

oh yeah and w/ the crank balanced torque WAY up too

Re: engine on the dyno
 

Gelner huh? let me know what HP you turn.
I've never had a motor built with out total balance, Thats like checking tolerances, you just do it. :cool:

Re: engine on the dyno
 

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" :D

Re: engine on the dyno

Re: engine on the dyno
