Can I get some help from some xray experts. Will the low ratio pulleys make a big difference when i'm racing in stock class? Is the solid center layshaft better than the one-way? The reason I'm asking is because I recently bought an xray with both setups but I only have the spur and pinion combination for the oneway. And if I change to the low ratio pulleys, that means I'll have to buy new pinions and new spurs since the ratios will be way off. If the difference isnt too big...I would rather save some money. Any help would be appreciated. Thanks
The low ratio pulleys were designed to "free up" the car. In theory the more free a car is the faster it will go. So yes there should be a difference in top speed. If it was me I would run the car with low ratio pulleys
. BTW You would only need to buy new pinions if you have the 128 64 pitch gear or 93 48 pitch gear. Hope this helps.
