RE: OFFICIAL RS4 RTR 3 thread!!!!!!!Also type SS and others
HPI and other engine makers like to inflate those HP numbers..i had a site that told me the real HP numbers of alot of the top motors, but seem to not be able to find it....but theres no way the motor will get 2.2hp on the xdyno.
Its still a fast motor though...on my buddys completly stock rs4 evo 3...i put a performance exhaust on there...and clocked him at 54mph...not bad for stock gearing..
