Re: first gear ratio change
I believe I'd run more gear, say a 513 or so. What's it turning at the MPH lights?

Re: first gear ratio change
Not a automatic guy,but I say same to few hundreds quicker,only thing I see that could help would be straight cut planetary may use a little less power than helical gear.
Strength will be biggest gain.IMO Mike Taylor 3601 |
