Please, if you are under the impression that 17.5s or 13.5s are slower than previously mentioned start gearing them up, wayyyyyyup. Everyone that has already knows this to be true. You may also need to take a look at your batteries, if they're not relatively new and well taken care of then you will need to update those to achieve the desired performance.
Also, the race results posted on the previous page are invalid as the drivers running in the brushed classes were far better drivers than those in the 13.5 class. If Dakotah had a 13.5 in his truck like he did at Cactus you would have seen a huge discrepency in times.
Sup Jeremy, this is Rusty's friend :P
anyways, i have to agree. After racing at Pegasus with my 13.5 in my B4 geared 34/78 (couldnt go any higher due to physical limits), i always had torque to pull and i had tons of top end as well, i would always fly down the straights and pull on the brushed guys as if i was a mod...was just insane power. I figure a 17.5 geared really high has the torque to push the gears which when high wil produce acceptable top speeds as well...
but ive voiced my problem with this before, the motor plate wont allow anything bigger than 34 for my b4. I cant gear my 17.5 the same as 13.5, it wouldnt work right...
i figured 17.5 in 2wd wont take off until either further milled out motor plates are released and/or Associated (and the other brands) release bigger reduction gears to lower the tranny ratio to allow for better gearing options, you know? I cant really attest to the speed or power of a 17.5 first hand though, but ive heard from other onroad guys that it isnt as fast as brushed. I have a 13.5 in my cyclone and it seems really competitive with brushed stock there, but it was just outright powerful in 2wd stock.
Anyways, some video footage of 17.5 vs. 27t at a track would be cool.
See of HB can hook you up with a few D2s and 17.5 systems to play around with at pegasus to see how that feels lol. j/k
