I'm using the Ofna 053, and in my buggy, the car feels really really good. Maybe even perfect. I may gear it one tooth up on the bell cuz the motor definitley has some mid to spare.

The truggy (D8T) however I am just pinned to the living hilt and I feel like I would do better in a B7. Some here make it sound like the B5 has "plenty" of top end. More "plenty" than a B7? My first impression is that a pipe could do a little magic to it, but completley change the delivery? In my truggy, again, pinned 90% of the time. I do realize that I will give up bottom. But for that remaining 10% of the track, I'de sacrafice it.

I'm not a stop and go driver into turns. Very wide sweeping pinned corners type. I do realize that once traction gets better that it may put a bigger load on the motor. But the 2 tracks I will take my truggy to most are very loamy and loose. This is why my motor is using everything.

Thanks for any help guys. I saw that the B7 has 2.75hp @ 38k vs. the 2.60hp @ 33k of the B5. Is this correct info? If so, that's another reason for the B7. I want a screamer!!
