The engine that powered Mark Pavidis
to victory in the
IFMAR 1/8 Scale Buggy World Championships!
| The O.S. OS Speed 21VZ-B V-Spec w/21H Slide Carb has many features usually
reserved only for the world’s finest high-end engines. The port timing has
been modified for greater mid-range and top-end power. The engine’s ceramic
main rear bearing nearly eliminates premature bearing wear and failure, and includes
lighter weight, lower drag ceramic balls that reduce rotational mass and friction
for higher rpm. About the hard-anodized crankshaft with tungsten slugged counterweight,
"R/C Car" magazine
writes, “The thing is simply a work of art” — resulting in a
significantly smoother-running engine. “The engine is a monster, in a good
way,”R/C Car"
concludes...and you will too! |
