I just can't get the speed, or punch out of the car I need compared to others I see running the same motor in different makes of cars. I am running on an outdoor dirt track, with medium grip, using the same tyres as everyone else. I have tried to setup my car the same as Ray Munday (at a different track and he runs mod) but still no good. I have replaced my bearings with AVID ceramics, I have replaced my diffs with plastic diffs. I have no clue where else to go to get this car to run properly.
Before putting in the fixed timing motor I cooked 2 Reedy M3 motors, then struggled to get a Trinity 24K certified to run cool enough. I have tried to shimming my diffs, changing the diff fluid, lighter batteries, heavier batteries.
Any suggestions would be appreciated from someone who is currently successfully running a B64D in stock. Thanks
IMHO I'd just try and run a different class if you could. I've struggled to get the B64 to my liking with a 13.5 let alone a 17.5. For me, it's a very sharp handling aggressive buggy. Great for mod motors or high grip/carpet. Aside from jumping ship to a different car or changing classes just focus on gearing to not smoke motors. IIRC I'm at like 24/81. Turn off any drag brake as well as there's enough friction in the drivetrain as is to keep the nose down in the air. Don't compare punch or top speed to other cars because it's all subjective. Lap times are the only standard of measure. You may have to just take different lines to keep your corner speed up if you lack the grunt off the line. I'm like you and I'm still not 100% happy with my B64 but I run a stock motor in a mod class and it puts up good numbers which is the only reason it's still around
