I know for sure that SPEC 3 is better (botton end, mid and high end power) than SPEC 2 I race LRP engines since the spec 1
the differences that i see lrp spec 2 to spec 3 are;
the top of the sleeve is longer ,to compensate, the burning room is also longer (inside ) to maintain same clearence- same head shims
the cranckshaft has black anodized on some parts with minor modifications
I do not know about timing if had changed
the conrod has two small risks on inside botton side like megas
the coolong head is little diferent
and back plate also
Maybe i forgot something but......
It's Ok Fabian, since i have RC Shop and distribution of several brands I have to be informed of everything, and I have good sources..jejejeje
I've had Picco engines since the old side exhaust and currently I have a JL Red Dot and a Picco Evo2 Edo Tuned, so I know a bit there and here about Picco engines...jejejeje...they are crazy fast.
From what you describe of the LRP Spec3 it seems to have same parts as above engines I have.... maybe difference is in timings and silicone ramp on cranks of engines I have, also my Edo has backplate with dished-in recess aligned with discharge exit of crank hole, also the crank bore is bigger than the one on the JL.
Please do post pictures on LRP forum, I don't want to abuse on Murnan's thread, which is meant to talk about his engines.
On a side note. We're having a big race here in Peru on April, with guys from Chile, Ecuador, Colombia......If you are interested in coming send me a PM and I'll fill you in with details.
