Default Pico .28 9 port P3 vs. Jammin .28 Off-Road

I am looking for an inexpensive .28 Truggy motor. Any pro's con's for these two motors. Which will you guys choose and why?

Also, how does these motors compared to the .28 Ninja?

The jammin 28 is 100% identical to the Picco 28... the only difference is the jamin has a 8 mm carb venturi and the Picco has a 9 mm venturi...other then that they are identical motors.....

the Picco's make more low end power then the Ninja, but the Ninja makes more top end and has a broder power curve..... the Picco's are long stroke engines made for tourque, and the NInja is a short stroke mill favoring high RPM......

exactly correct. i had a Picco .27 and it was a torque powerhouse, but coupled with a JP-2 pipe it was very well rounded. i personally think you should go with a torquey engine, since that's when most racer's need the power. only if your track has a long or a lot of straights would i go with a high RPM engine. i would go with a torque engine; it will get you scooting around the short sections and up the jumps in a hurry.

they are actualy 100% the same.. I have personaly modified and timed both motors, the only difference is the venturi's, other then that the differences are just cosmetic....

IMHO the P3 28 has too much bottom end and results in alot of wheelspin...... if you have the $$$ the Ninja 28 is a better track motor.....

do you think this could be counteracted with a top-end pipe?

you cant counteract wheelspin but you can help increase topend.

can you counter act by going up a tooth on the pinion? that will reduce the bottom and increase the top, right?

you can, but the feel is not the same as a revvy motor with lower gearing....its much easier to modulate an engine on lower gearing... As well you will find that geared up with a 28 that you will start smoking clutches and CB bearings.. on a modded 28 we couldnt finish a race with anything but stock gearing...... The Picco is a fantastic motor, and extremely powerful, the modded Picco 28's can be ballistic.. But regardless the Ninja is a better track motor, the power is smoother, the powerband is broader, and the power is very strong in the top end, where the Picco will fall off the Ninja will keep pulling..... As well even though the Ninja has great top end it also has very good bottom end, it pulls evenly from idle to 40 000 RPM...... But for sheer power the Picco is superior, but for a motor that will give you razor control and endless top the Ninja is my weapon of choice.......

This turned into a huge debate on OFNA's own web site already. Sure enough, it didn't last long before getting deleted. No one could make a case for what specifically is different between the two other than quoting the advertising.

Not trying to argue at all, just stating what I was told. I could be wrong though.
