I just got the polini hi speed, I had to customize the noon moveable drive face to get the pulley to go all the way together. Other than that I love it, high revs right off the line and settles into nice cruising rpm. Get rollers with it because mine came with stupid light weights, like 4.9 & 3.5. Don't expect much gain with a variator alone tho, you'll be disappointed.

UPDATE: I am still waiting on my jets and then have to find time to install them. However, I got +4 MPH simply by optimizing my tire pressure.

I am going to get a new contra spring and new roller weights. I need a new spring regardless because by hill climbing is sub-par but would putting new weights in a stock var be worth it? and if so, what weights sould I get?

When you say optimize did you over inflate the tires or just made sure they were the correct tire pressure ?

I must check into to that. Do you have a good tire gage to get accurate pressure reading ?

$10 digital pressure guage from walmart. seems to be pretty accurate when tested against my Acura TL's TPMS pressures. Did have a tough time getting a good reading from the rear tire though. Not exactly sure why.

Dang that's still low, go 40 in the rear and 35 front to gain even more speed. Also yes sliders will help with stock, but you'll want to get 7-8 g especially if you plan to get a stiff contrast spring. Stiffer spring = heavier weights to pull through that spring.

max PSI on the tires says 32 PSI.... If I am going to get sliders will I want to get 8-9 g then? I've heard that the sliders act about a gram lighter than rollers. Yellow spring?

Red spring week rip up hill but most likely over rev past your power band. Those tires could handle 100psi before blowing, I run 40psi on my zuma and it increases to speed quite a bit. Yeah I would try 8g, 9 would be to much.

soooooo yellow spring? I could go for a stiffer spring right now just because when I approach a hill my revs are waaaayyyyy too low. Hopefully 8g sliders and a yellow spring will be a good mix with what I have.

Not to hijack but stay on subject, what would the a guess on the ideal rollers be with a yellow contra spring change ?

I am reading that people blow their belts if using too high of a PSI Contra Spring. So what is the stock spring in PSI ?

I would have to guess around 1000. Does anyone know what dimensions the stock rollers are?
