Default My New PICCO P2

Well, I installed my PICCO P2 into my T-Maxx today. Even at VERY rich power settings the thing has tons of torque!!! I had it soo rich that the thing would hardly run. After about six tanks following the reccomended break-in procedures I think she is ready to be tuned. I am however a little concerned about their being too much power. I currenty am using an RD Logics tuned pipe and a Motor saver air filter. Would someone please advise me of the optimum temperature for this engine? I used to set my TRX 2.5 at about 270, but have no idea for the new one. Also, I am using 15% nitro fuel/18% oil. Thanks.

I have the Orion Wasp .21 (which is the exact same engine, it just has a different color head) and the manual said to run it at about 180-200, but mine likes to run at about 220, and I've heard others who have them say about 230.

I have another question. What is the best gearing to use for my setup? I don't really care about super fast top-end, but would like quick acceleration (but not so much that it is constantly flipping over). I currently am using a 18 tooth clutch bell (I believe that is stock, if not, I am using the stock clutch bell that came with the truck originally) with a 70 tooth spur gear. It seems to work pretty well, but seems to bog just slightly at the start. However, I am still running really rich for the break-in. Thanks for your advice in advance.

Well for one thing, this thread really should be in the Tmaxx forum, not the MT forum. You'd get more responses that way.

The stock gearing is a 20 tooth clutch bell and a 72 tooth spur gear. As long as your truck isn't super heavy (tons of aluminum aftermarket parts) then 20/70 gearing with that engine should still make wheelies. If it's a little boggy still, then you need to spend more time tuning it. You said that you're still running it at break-in settings........that's the reason it's a little slugish. Get it tuned in a little better, then determine what gearing changes you need to make.

I've got the P2(Ofna) also evan. 200-240 deg should be fine(IMO under 200 is losing a lot of performance). Stock gearing(20/72) and your Maxx will haul *****. Thats what I'm using and I will try my RRP 21th bell soon. I think this motor will pull most any gearing, so gear to your terrain. That motor sure deserves 20% nitro...
It would be interesting to see the P2 Maxx run against a P3 Savage...
What a shootout!
Enjoy your rocketship.

Just this past week I put an OFNA Picco .21 Maxx engine with RD Logics pipe in my Kyosho Inferno TR15 (I guess now it's a TR21) 1/10 unlimited dirt oval car. The engine in the photo is my old Fantom 15.



The detail sheet that came with my engine states "a normal operating temperature is around 220 to 270 degrees".

So Orion says 180-200, Werks says 210-240, and OFNA says 220-270?

Hmmm.

Yes, I've done many modifications to accomodate the change. Fortunately there is minimal cost and only a moderate amount of time necessary. I removed the radio box and relocated the throttle servo next to the spur gear (center of the chassis) to accomodate a slide valve carburetor. The fuel tank was moved forward about half an inch. The engine is not a direct bolt in. I used OFNA adjustable mounts and cut new mounting holes for the engine mount. I'll start a new thread next week for that project car.
