A lot of people come here trying to go "faster". I always assume they are racing their friends up and down the street and most of the advise given is to help them drag race. But when it comes to the track, sheer horsepower and speed hardly ever win the race. I have always been faster with a stock motor in my b4 than a mod motor. One way to make my lap times crap is ad a bunch of speed. But... If your a pro level driver and can handle and utilize the power to your advantage, then its butter. So like 2% of us need max horsepower for racing. I run a reedy 540 7.5 and I can keep up with everyone in my skill level. I just have to watch my temps.

I recently had an issue like mentioned above with speed. I was running a 13.5 in my b4 buggy. And there was a double that literally everyone cleared. Even the novice drivers with their rtr kits cleared it. But I was casing the jump. I was running my esc blinky even though no one else did. It was blinky from MOD the week before when I ran a 10.5. So, I went into the esc and added 20% of variable timing. Ran a few laps and temped at 120ish. I was now able to clear the jump, but the little added power was not over whelming. BTW it was not a hard jump, it was just spaced far apart on the back straight. Like I said all of the novice could do it clean. Anyway, just thought I would share.

** Also, I agree with cherry about smooth power. I would never keep a motor that was not smooth.
