What can i say guys, we are getting phenomenal mileage with the B5's, tho of course ours aren't stock

I don't have any stock Ninja's or B5's to dyno...I do however have access to a stock Speed and the new V-Spec....will be dyno testing the new V-Spec this week.......

I don't care how much you guys persecute me, I feel all the top .21's are very comparable to each other.....No one engine seems to pull the other when they run side by side...most people pit at the same times... I see just as many poorly tuned OS engines at the track as any other brand.....I see no advantage whatsoever to owning a OS over any other of the top brands...
