"the 3-port produces in excess of 1,6 HP the 5 should be in the 1.75 range. "
Now i wanted to know if anyone has used this engine ..... and how's it performed....
Actually i am in need of an engine for my V one RRR and wanted to get somethiing exceptionally good.....
all the help is appreciated..
Lamberto Collari Motorsport makes the following versions of that engine, and are based over world champion Sirio engines, not Picco
LCM12PRO-3E Standard AAC EFRA Turbo
LCM12PRO-3E MC Mauro Collari Modified AAC EFRA Turbo
LCM12PRO-3I Standard AAC IFMAR Turbo
LCM12PRO-3I MC Mauro Collari Modified AAC IFMAR Turbo
I have the Mauro Collari modified EFRA version engine, and it is ballistic, and is faster than any of my past Nova based engines. Just remember that being an AAC engine it needs to be warmed up properly to get the right carburetion, it can be misleading when it is cold. It takes more time to warm up than a regular ABC engine. At the start of a heat it will look as if it is rich, but once on temp it rocks and runs like a mad dog.
Another thing; it loves cold plugs (7), it works best with Sirio's own pipe, and it needs to be geared at least one tooth shorter than Nova based engines (power curve is higher).
This is what Ron Hopkins, from Werks Racing, the USA importer has to say about them
“Thank for your interest in the Lamberto Collari Motorsport line of engines.
The new .12 engines we are bringing are the IFMAR spec engines which conform to the new ROAR crankshaft rules.
This engine comes with the modified sleeve with tear drops on the transfers (like JP or NovaMax) but without the additional massaging of the hand modified Mauro Collari engines. You get about 90% of the performance of the hand mod motor at a significantly reduced price. The engine features AAC construction in addition to the new low CG cooling head design.
For the true horse power junkies we will be releasing the hand modified engines in a couple of months but these will be really limited production motors.
The first batch of .12's and the one that RC Nitro Magazine dyno tested was the standard LCM engine. This 3 port ROAR legal engine was according to them The most powerful .12 engine that they have ever tested including 5port Novarossi's!
Just to give you some specs on the LC12Pro3 I courtesy of RC Nitro Magazine
Peak Torque 58 oz-in
Peak Torque at 19,600 RPM
Peak HP 1.6
Peak HP at 33,700 RPM
Max RPM 41,000
This is with 20% nitro fuel!
According to Steve Pond from RC Nitro Magazine, the pipe used was a 2 piece Novarossi 51602 with 1/2" gap between the manifold and pipe”
Hope all this info helps on your decision
