Outlaw, whats your gripe with Silber? Honest question. There are lots of customers reporting great running sleds from Silber, I am one of them. There's a possibility that it leaves a fraction of a percentage of efficiency on the table, but I don't notice that in any way at the boost levels I run, nor do I care to look into principles to find that fraction because the thing flat out rips. There's theory and real world I guess, I'm happy with my real world experiences, and I believe there are a bunch of others in that category as well.
Have you ever ridden with a Silber axys kit? If not I'll be on the mountain bouncing around CO for the last two or three weeks in March straight, come on out, tell me how poorly my kit runs, then I'll show you how great it actually runs. Seriously though if you want to ride let me know, i'll be around and always looking for new people to ride with. It sounds like you know your stuff so I could probably learn some things!
My biggest point is if people are happy that's what matters. Also, since when do people not make decisions based on price at all? If you said you couldn't have a turbo because the $8000 kit you want is out of your budget i'd tell you you were nuts for not trying one of these, they bring the fun factor up so much its not even funny.
PS I didn't time my install, but was probably under 3 hours taking my time. It was the first time taking the hood off my Axys so I wasn't familiar with it, I also removed the seat and tank like it was a pro which you don't need to do anymore so added a little time there. The only thing not easier to do on the Axys is the clutching I think, that's the same as the pro, because well they are the same clutches...
Anyway let me know if you want to ride, because at the end of the day thats what its all about!
