For more than 13 years Mauro Collari, father of the 6 time 1/8 scale World Champion, Lamberto Collari. has been modifying standard engines to obtain the maximum power possible. Every piece is hand picked one by one, to have the exact tolerance, and each labor is done manually, with the maximum precision, there, where machines can not possibly reach.
Unlike most engine tuners who disassemble then reassemble an engine, the M.Collari line has access to SIRIO engines from Star Motor Company.
In addition to a hand selected and fit Piston and Sleeve. It features a polished exhaust port, modified transfer ports, and enlarged boost port cavity in the engine case. The crankshaft is balanced after deepening the primary flute on the face, and after opening the timing. It has a specially designed low center gravity cooling head, for which the upper two fins of the block are machined to allow the head to sit lower. This engine series is assembled in small batches, individually.
LAMBERTO COLLARI .12 ENGINES
Lamberto Collari Normal .12 AAC 3-Port EFRA Turbo Engine
LC12 PRO 3E 1.52 hp @ 39,000 rpm
Mauro Collari Modified .12 AAC 3-Port Turbo Engine (EFRA or IFMAR/ROAR)
LC12 PRO 3E MC 1.68 hp @ 41,000 rpm
There is no problem with the composite 3 needle carb. That is a problem of the past. This engine is simply ballistic. I think it is the fastest engine out there today, very similar to the engines that just won the 200mm worlds in Brasil.
