There have been quite a few posts on this if you do a search...in a nutshell:
Valin has done dyno testing and was generous enough to share his findings.
Valin says it looses horsepower on his 780.
I have them on both of our SXs[redheads] and they work very well.
I had one on my 2002 SRX and never saw any improvement and once I read Valin's info I removed the boost bottle for this season.
Don't know why they wouldn't work on the SRXs but have to go with the facts!

We have approx 12" of ice...trucks + ice shacks have been on the lake for about 4 days...short ice road in the area is open as well. We have only about 6" of snow on the ground for now. The deeper trout lakes in the area are probably not quite ready for riding on yet, but soon.

would a boost bottle help more if you were running aftermarket pipes and reeds? dynos dont lie, but waunder how throttle responce would be compared to stock guess i got to buy one and try it out

any posts ive seen so far says they do really well with non powervalve motors but with powervalve motors dont do much and actually loose after like 7000 rpm or something like that, cant remember the rpm # but it was in the higher rpm range.
