I realize that some manufactures exagerate there numbers. Believe me I do. But a mach .15 doesnt make any where near the same hp that the .12tz does yet they almost have the same numbers. Believe me I know that 1hp is a heck of a lot of power. Especially for these engine's. But these numbers dont make any sense with some of these engine's.

A MACH .15 rated here at 0.65 hp doesnt even come near the power of a .12tz t3 which is rated ahere at .80 hp. If you have ever owned a mach.15 you know how much power they really have. If you then have a .12tz t3 you know how much power it really has. And they dont come close. The .12 cvr is more powerful then the MACH .15 even though they dont have it rated here it would have to fall bellow the MACH .15 in power. You can definately tell the power difference between the .12 CVR the .12 TZ T3 and the MACH .15. There are huge power differences between them. There numbers for some engine seem right. But for others it's seems really off.
