I think they have about the same overall power...Jammin might have more low end. My buddy's 8T with Jammin .28 pulls pretty hard out of the tight turns.

I prefer the OS .28xz though on my XT8...

The shape/color of the cooling head, the color of the backplate and the carb restrictor are the only differences.

Good eye...and yes I do run a 053 and love it! I also love the fact that this os .28 feels like its going to rip this truggy apart every time I run it because its so powerful!

You think I'm crazy for running this pipe haha?

When I need more power I will get a stage 2 race mod done to her and slap the 2060 on there. Then you can really feel sorry for the truggy.

I ran the tsais truggy pipe on my p3-28 in a lsp. I geared up to a 15 tooth clutch bell trying to tame the bottom end power. With my old JP1 pipe this motor was strong but run out of steam on the top end in a hurry. The Tsais pipe had a much larger stinger than the normal 21 race pipe and really opened this engine up. I could actually run down modded v specs on long straights but every time I made a turn I had to make sure I was lined up straight before I touched the throttle or crash. It just seemed like I could never put down consistent laps with the .28. I could with my old WS7 II but I could not make the short run up jumps with it because it was too soft on bottom end.

A modded picco 28 should be smoother but I would go with a good torquey .21 like the jammin jpx, P5X, plus21-5, ninja jx, go 5 port, or similar.

the only real difference is the crank timing..a Picco P3 FTT has more crank timing makes more power and uses more fuel , the JPX has the less timing and gets better mileage but has a little less power....One thing tho with the P3 28 FTT is there have been some running timing changes in the motor, the older motors had extremely high crank timing, the newer ones are are a little more conservative, however still not as conservative as the JPX...Another thing is the new Picco P3 28 carbs have no removable inserts, its just a fixxed 8 mm, whereas the JPX carb uses inserts which allows more tuning options........ ANother odd issue is I find the Picco cooling head to be prone to losing fins, the Jammin cooling head doesn't have this issue.... myself I Prefer the JPX for modding over the P3....

Thanks for the detailed info! I would have to go with the Jammin because I'll need to run a pretty small restrictor. Am I right to assume that timing is changed when you mod a motor?

I am one of the very few who alters both sleeve and crank timing with my mods, I even go as far as reshaping the main transfer port inlet angles to improve the engines loop scavenging.....my work may look pretty but it goes much deeper then just cosmetic changes to the sleeve and crank !!!! i spend at a minimum of 6 hours on each engine , as well with Picco's I will lap the carb slide to ensure it glides free and smooth, I will also seal the needles and carb body against any potential air leaks.....from day 1 the motor will run like Clockwork !!! LOL pun intended
