Best motor for 1:10 truck on 8 cells?

[Rtsbasic]

Coolhandcountry I totally understand where your coming from and appreciate your input :)

I am compensating for the bigger tyres by gearing down, currently at 14/90 in my T2 which gives it the runtime and acceleration I want, but not the topspeed to really take on the local nitro competition (its topping out about 40mph I think on 7 cells). Increasing the gearing dramatically reduces runtime and hurts the acceleration on this motor.

OK then, crunch time, the 1920 is at this moment in time beyond my budget (because I'm picking up another controller as well). So if I got the Feiago 540 8s, and ran it on 10 cells, it wouldn't overrev (probably about 45-50K under a load, but also very powerful on my current 8 cell batteries?) and would have more power (accel, and top speed) than my current 6s on 7 cells?

Basically if the 8s will make my car go faster on 8/10 cells than my 6s on 7/8 cells, its time to crack the wallet (erm, paypal account) out :)
