There is better power with the t1 box on my bike and BETTER is the key word,because I do-not have proof and do not need to prove anything.Tom, let me tell you a little story about 900RR's
Years ago I used to do a lot of jetting work for the dragracers in Memphis. 900RR's were fairly common and would whoop on a GSXR1100 only if the bike was properly jetted and the rider did everything exactly right.
900RR's in stock form had a dip in the power around 6000rpm and if you had the throttle pinned to the stop, in first gear acceleration when it came out of that dip it would lift the front wheel into the air.
Now when I would jet the carbs I would make the power delivery much more linear and it would remove that dip in power in the midrange. With the bike making better power through the midrange it would no longer loft the front wheel so early in the rev range instead it would take another 1500rpm or so before the front wheel would leave the ground. The rejetted carbs are now allowing the engine to produce more power throughout the rev range and the dyno charts backed this up, but the bike no longer snapped the front wheel up just past the midrange dip like it used to so some of the owners of these bikes complained and literally wanted me to put the old jetting back in because it felt faster to them when that hit of power would yank the wheel up.
The point is without actual baseline and end dyno charts to verify the results. It is all subjective even from you Tom...
Ultimately do any of you guys know of any other bike that has ever got 6-9 horsepower from an airbox mod alone? If some guy showed up on this forum claiming his ZX-10R or SV650 gained 6hp just from an airbox swap every single one of you guys would call him out on it, but when RC51 owners make similar claims it must be true.
It makes no ****ing sense whatsoever.
I was in the cell both times gains were acheived.
B.T.W 900 rr's are /were wheelie prone to the point that HONDA moved the cg.
If you know where one of these bikes is it would be real fun to watch Jamies Spragues (Sprague speedtuning) 1998 gsxr 11 have a go at it
