i saw with eduardo's (picco) radar both kyosho sirios powered cars and serpent powered by piccomega reaching 108km/h......

I also think MAX engines reached this top speed or something very close to......

but when we say FASTER, it sounds like a huge difference, when actually the difference is smaller than 1 ou 2km/h.....

There is a 100$ diff in both ? !!

Did some googling.. and found out that the JP pistons are rare !!!

Should go in for the M collari ??? can a M collari piston be replaced with a standard one ? ??

Any one has dynoed these 2 engines .........
Based on what I saw at the WinterNats, the JP is very fast. Both of Swauger's cars were probably the fastest. I know he is a "Factory Team" guy but damn his cars were fast!

winternats = 30% nitro....or am I wrong??

if you check the world championship results you'll see that JP engines were beat by far........

kyosho sirio guys did 17s high laps.......other JP guys couldn't do better laptimes than 18 flat/mid.....

huge difference for top level drivers.....

I believe that most people were using 30% at the WinterNats.

I cannot explain what happened at the WC but I believe that Swauger's 1/10 scale car was as fast as Michael's if not a little faster. Swauger's car didn't last long in the main so I didn't get a real good look. Maybe it's not the engine, could be setup, gearing, fuel, etc... who knows?
