How to improve my 660 zero to 30mph power

bdooners1 · #1 09-27-2009, 05:03 PM

My 660 appears to run great and has lots of "stuff" but can be out pulled 0 mph to 30 mph against a stock 660's. Any suggestions?? Would a MSD coil help? which model#? Its top speed two up is 56 mph.
My Rhino has a "black Rhino" performance cdi, modified sheeve, jet kit, 27" Zillas, snorkeled, gauges, roof, w/shld, and 2700 miles on it.
Any suggestions? bdooners1

What weights are in your sheave? What secondary spring are you running?

If you are getting pulled by stock rhinos I would have to believe your prob is ur tires ! You can get diff weights for your sheave it will help the bottom to mid ! I would start there or if you still want more do a cam

yep, I have to believe the 27" tires are killing the off the line performance - takes a lot to get them rolling compared to to 25's

My weights are stock ones in a modified sheve. I'm running a "Black Rhino" performance cdi too. What weights would you recommend? Thanks for your help, bdooners1

Im running 13g weights and it gave me a huge diff on the bottom end Keeps the rpms up alil but still can do 60 with a 4 seat LT rhino with only bolt ons. I know that some of the rhins with the older cdi box had a stumble off the line so that might be your prob, I would try the weights first.

pretty much the only thing that is going to help is stock size tires..........

Clutch weights make a huge diff. On the 660 IMO and I can say by experience as well ! Stock tires will help A LOT as well

jr do think the clutch starts moving open before 30 mph???? i didnt think it would start to open till 30 to 35 mph????

I ran mine with the cover off and it does move right away.....may not be open all the way but still the weights play with the rpms the clutch operates in ! I have ran stock weights and 13g I can say that there is a huge diff. The first run out with the lighter weights I started to swap and almost hit a wall in the wash. Maybe its cause the rhino runs at the peak rpm when everything engages but if it didn't engage before 30 how is it moving ?

13g weights and what spring are you running? Where can we get these from? Thank you.....

I get all my clutch parts thru AzCourt ! Court is a good guy that used to have a shop and does stuff now to prove a point....I'm running a Orange Epi spring and Courts sheavewhich has No roller flop. I have a delay on the stop to start but once it whines up it goes, I have been told that is the effect of running a lighter weight ???? Not sure but Love my set up just which I had a cam

He is on RF and Underground ! The weights you can get else where he just a has great price and is easy to deal with IMO

ok maybe i didnt get my point across...yes its turning....but is it closing at that low of speed???
