Gear ratio's and top speed?

[almighty15]

Hi guys

Just put a Zenoah ESP ported G320 in my 5ive and it only goes 32mph on wet grass, it's running stock gearing.

I'm looking at upping the gearing to get more top speed as I was expecting more then 32mph stock if I'm honest.

With the HPI there's quite a lot of information around in terms of what top speed you can expect for any given pinion/spur gear combo.

Is there such a chart for the 5ive? I'm ideally looking for 45mph while keeping as much acceleration as possible.

I went to a 20t and only went 35-36, stock was close to yours 31. Have a Demon two speed now only 39-40. What pipe do you have i'm running a Bart32. I think the smaller motors rev more for better speed but lack the low end torque. Some say the bzm micro, victory, or quickdraw pipes help but I don't know for sure.
