Anyone using Muzzy Velocity stacks ?
Just wondering what kind of gains can be made by adding velocity stacks.

That is correct. The heights are different. We do not consider the velocity stacks a "power producing" item but rather a tuning aid allowing the builder to emphasize certain parts of his power curve (peak power, peak torque).

I have gotten 183 on my Stock 12 with the BMC Race, 1st generation Step Hindle and short Bear Stacks. entropy, is this the 1361 that you had some crank problems with?

Vincent,
I never had crank problems either with the 4mm weldup or the 4.6mm billet cranks. I did torch the bearings on the 4.6mm once, but that was due to the oil pump drive shaft parting. (crank just needed a bit o' bending to make right, and it is still fine)
Although my 1361 only showed 193hp max on the dynos, it ran 9-teens @ 152-53mph pretty consistently even with my TFA status. 1/4mi mph tells all

Somehow, My post did not show up! I posted that someone either in Texas or Arkansas had an engine built by someone that did Legends cars and wiped all of the bearings when he put it on the Dyno! I guess that was not you!

MPH don't lie!
Karl, when your bike was running 158 mph with yo big azz on der, it was making some serious freakin power. I bet 220hp or so. That sucka would have gone 161-162 with MOI on it. Too bad it wouldn't start and would eat bearings and head gaskets for lunch huh?
You are going like 155 mph now right?
