In the last 2 years I've ran Go motors, Vspec's, MR Ninja's, Novarossi's and Extechs and by far the best motor has been the extech in terms of fuel economy and power.
I know what you mean. Alot of people like to get caught up and jump on the "dyno is just for numbers bandwagon. Trust be told the dyno tells you exactly and consistantly what power your engine is making. It also tell you where its making all of its power. This is very usefull. The bes thing about a dyno is that it tells you the most important thing about an engine. Area under the curve.
Ive also noticed that just about everyone has XXX engine that blows past XXX engine. How do you know how well that engine is setup, running and tuned? you dont. Any engine can be slow. Its making them fast is what takes skill.
The Vspec is the best off road .21 ive ran into. It makes .28 power and actually holds the power in the top end. It also likes to spin RPM and sips on fuel. If course i can take the same engine and put some crap fuel in it with a JP3 and the wrong clutchbell and get dominated by a RTR engine.
The extech is OK at best. The RACE PREPPED EB Mods one only made 1.38HP on the xdyno(the same dyno EB has) Other than that this engine holds the power for a little bit in the upper RPM range it doesnt do it as well as even a stock VSPEC. for 450 it just seems your paying for a name. That money could be spent much much better. You dont haft to listen to me i understand you have your pride and all.
