Thanks guys !

the engine didn't lose any bottom, in fact it makes slightly more initial bottom....but run to run on the dyno its difficult to hit the start button at the same RPM every pass, so there is some fluctuation at the intial start of the curve run to run..with 2 people it can be done much easier then when I am by myself..By myself I have to take my hands off the throttle/brake controls and activate the start key on the laptop...which usually results in a slightly less crisp initial start as to when a second person hits the start key for me !

Looking good Neal looking good. Would be nice to see some track time with that engine I know I absolutely love the stock xz speed's your modded speed should be off the hook.

That track in the pic is the nitro pit they are not all like that out here. But at that race there were over 400 entries. Thats what happens at the nitro challenge when the dirt crew puts on the show. James gets to race on that track regularly I am still waiting for my beam me up Scotty portal. It's about 750 miles away from me but I'll be there in feb for the nitro challenge it's my fav race of the yr.
