Good question... If you do need a new rod you never know what you get.

I thought to own one of those but seems too expensive!!

I think you've made the most informative post about engines that I have ever seen here and I see it at the track every week.

Nova fails, they go Max, Max fails they go Sirio, Sirio fails they go Picco, Picco fails they go back to Nova and the cycle starts over and the racer is unhappy and believes the engine is fully at fault (and sometimes is) but each manufacturer has released a new 100% better engine by the time they get back to them.

The evo4 is an improvement on the evo3 for durability, the rod lasts twice as long in my experience and I haven't broken one yet but you can actually feel when it's getting loose unlike the evo3 but I changed rods every gallon "just to be sure" but at a cost of around $20 retail on the 3, is it that expensive? I know some of you run engines for 30 gallons, I don't.

One thing I haven't kept track of in my years of racing until recently was the fuel we use, every one of us has a local fuel guy that mixes some great stuff. Then you have the production fuels like Byrons and Nitrotane among others. I have seen problems with the home stuff and the production stuff depending on the batch and chinas supply of nitro. Just recently I had a case of Byrons 25%/12% oil and I had to add a cap or two of oil to get the proper burn that left the top of the piston with a slightly wet look and the crank wet after running. I burned a piston/sleeve assuming that the 12% oil label on the bottle was correct and ran too much before consulting an expert when my power dropped off on my .21. We popped the head and sure enough, there was not enough oil which caused excessive wear. Take a sharpie and try to mark the rod right after you run, if it writes easily then you don't have enough oil and 9 times out of 10 the engines I have seen lately fail have all had a lack of oil where something seizes causing the rod to break.

I've had three gallons on a JL3. Changed the rod religiously just before the end of the gallon everytime. Still runs great and still has plenty of compression. I run it with Maxy's 30%

I recently replaced it with an Evo4.

BTW, that P1 motor doesn't exist at Kamikaze. I know because I bought the Evo4 from there. Its the best Picco they have

B.S.

Where can I buy it?

Anybody tried this engine (or EDO mod) or see it in action?

i have seen it in action and it looked very good, both low and top-end. It was a picco evo4 edo modified.

ran the .12 evo4 non mod this season. with the 2651 pipe i got 6 minutes runtime safely. for me, the engine ran best with a lean bottom end and a neutral top.

engine ran great from 200-230 F. drag raced an os tz spec2 - seemed on par.

i guess not many people have good luck with these engines... I've enjoyed mine a lot.

cant wait for the next picco
