Great engines, I would say its power and speed is in between the WS7III and C6BB. Parts for these engines seem to be quite expensive however.

I run the P7R EVO in my Jammin Truggy.


one word...incredible!!!!!!!!

lots o power.

The reason the parts are expensive/hard to find is because it is a discontinued engine in the Picco line up.

it has been replaced by the P7R EVO 2...little bit smoother on bottom with a wicked top....

highly recomended powerplant...either one!!!

My wife runs the P7 with a JP2 pipe on her Hyper 8.5 and it's awesome.

Adam from AB mods has done extensive dyno testing with the Picco P7R EVO 2.........The JP-1 and Picco 069 kill the motors top end, the JP-2 doesn't do much better........The absolute best pipe on that motor is a 9886/086 on a short conical manifold..the second best pipe is the TTR 2035 on a short conical manifold, then I would choose a 053 on a short conical manifold...................For situations where your willing to sacrifice alot of top end for better low end the TTR 2035 on a long header works wonders...the Picco 069 and JP-1 do give the motor good bottom end, but they totally kill the motors top end, and the bottom end they give doesn't match the bottom end of the TTR 2035 anyways........If your running a EVO engine on a JP-2 or JP-1 or Picco 069 your only seeing a fraction of that motors potential output......Also that motor really responds to having a short header, the difference is night and day .. As well equiped with the right pipe and header the Picco P7EVO2 makes more HP and more torque then any offroad RB .21 including the C6

I'm running the Evo 2 on my RC8 with a JP4 pipe and holy crap its fast. The track I run at has a 145ft straight and it doesnt see full throttle before I have to stab the brakes for the first corner. I was running the Thunder Tiger bottom end pipe on it and it revved quickly but quit pulling. I also got over 10 minutes on one tank in the RC8 with the tank insert removed and the engine was running at 220 degrees so there was a little more there. Has a little over a gallon on it and the piston still sticks at TDC.

Here is 3 dynoes of a modded P7R EVO2 using different pipe/header combinations. Also I should add this P7EVO2 has been used 1 full season of racing, plus has blown a connecting rod. luckily when it blew the rod it only put minor damage to the piston and sleeve...just a slight nick...... anyways the motor still had excellent compression so I put a new rod in the motor and sent it off to be dynoed.. I am very impreseed how strong this motor is, even after a season of racing and blowing a connecting rod.... I mean with the 2035 pipe this .21 is hitting almost 68 oz/in of TQ, that is awesome IMO...

alright guys here the deal


his is a Picco P7-R EVO motor that I bought new in September. I broke the motor in with a little less than 1/2 gallon of a combination of heat-cycling on a bench and slow driving in the street with the body off to keep the temps down. After breakin, I took it for it's first race, and it performed BEAUTIFULLY! Holeshotting against some SERIOUS motors! About halfway through the 20 minute main, it started to lose power and flamed out. It never started back up. I took it apart and inspected for damage or dirt or any of the common issues, but found nothing. So, I sent it back in to OFNA/PICCO in California to have them take a look at it. The technician said he could offer no explanation for the occurence, but went ahead and repaired it under warranty. So, here's where the "NEW" part comes in: he replaced the piston, sleeve, rod, front/rear bearings, wristpin, carb needles, head button, & backplate seal. The carb was also reset to factory settings on a flow bench.

So, this motor is basically new and has not been started since....will need breakin completed as if it was new out of the box. I have included a copy of the work order from OFNA to prove all of this. The only things that aren't new on this motor are the case, cooling head, and crank......and those only have about 3/4 gallon on them!


ive seen the paper and like said all been replaced and like new...what u think its worth?

Whats the inner bearing size on the Evo 2?? I am thinking about trying some TKO ceramics just for the heck of it. I ran ceramics on my Jammin truggy and they made a noticable difference, just wondering if it would do the same for an engine.
