The 8.52 was run without a PC ( NO fuel tuning of any type )and using 89 pump gas .. At that time i was using Brocks alien head 2 proto type pipe .. I now have the production alien head 2 pipe on the bike and ran the same 8.52s .. Brock tells me that the CT, alien head and short street smeg all make the same HP on the dyno ..The alien head and street smeg being the cheapest price of the 3 pipes .. Hope that helps ..Lee, just to clarify, you had no kind of fuel management when you ran your bike to 8.52 ?
Also do you ride on the street or all track miles?
Looking at getting the alien head 2 for my 14r, but kind of waiting to see what all comes out.
Very nice Frank. If you could straighten out 7500 to 8500 range it would be a nice curve. But all the Busa's have there flat spots to.Yes, a stock 2012 ZX14 with a Brock CT Full Exhaust and the latest Ecu Unleashed Tune file . . . .

Frank I'm curious. The second graph you show you said stock Unflashed ecu and show only a 8hp gain. Was this one with the stock exhaust as well or with the brocks pipe but before the flash?
Just curious if it made the 200 stock or not? Either way they are impressive.
Spkrdctr said:I sat on the 14R and it was too sport bikey in position for me. Is there any way to raise the handlebars 4 inches straight up and 2 inches towards the rider? That would equal my BKing and then I'd be all comfy. I'm waiting for ABS on the 14 too.
8hp and 5ft-lbs from the reflash...VERY sweetHere is the same chart compared with a stock (unflashed) ecu . . .
FrankAs you can readily see, the new curves "mirror" the old ones, as they often do when you are correcting fueling. Hp and torque on normally-aspirated bikes are always "bell" curves, and their shape is associated more often with the layout of the engine: cams, cam timing, intake-tract shapes and valve sizing, and largely, exhaust. Unless there is a dip in the fuel curve - which in this case, there is not - you cannot change the aspect of a hp or torque curve just by changing the AFR. And as for it having a flat spot - this bike is a monster everywhere and shows absolutely no hint of an issue anywhere in the powerband.
