Maybe so, but dont forget ive modded my Go Tech and even against other buggies running V-Spec engines at my local track i would say the Go Tech still has more top end than OS motors that run at my local track with various other pipes. Ive run down many cars that are BIG Dollar engine with the Go Tech, great motor, hey maybe ill try a few pipe combos out soon, but from what ive seen the Go Tech craps on most motors ive run against in terms of top end, its IMO even faster than the 7 port version, maybe its just my pro mod work :]
V-Spec is still stock, but that may change soon too.

Not to discredit your findings, but coming from an Ex Drag Racing Scene, the amount of times ive heard the word "Dyno" and actual on track performance i always take it with a pinch of salt.

Here is two videos of the motors on the same track, sure one is a hyper 8 pro with the Go Tech and a 14 tooth clutch bell, and the other is a MBX5R with OS and 13 tooth clutch bell but you tell me the OS has less power out of corners, I beg to differ. Yeah i crashed the Hyper 8 just before the main straight and got a lean bog coming along the main straight but its got more top end than a OS believe me.

That is NOT my local track either, but ill tell you what ill do, ill put the OS in for a meeting and then next meet ill try the Go Tech and we will see what the results are. Im gonna be trying a JP-1 and maybe a Jp-3 early next season, with the OS but i may buy another pipe, whatever is reccomended with the Go Tech and give it another run, but as it stands atm the Go Tech is now in the Tool box as a spare cause it lack the bottom end power that the OS seems to put out. Bear in mind the OS is very new and not fully loosened up either.

Sorry if i sound like a sarcastic prick but i know what i know.
