Hey Dallara - how's it going?
I haven't seen numbers from someone who has all that stuff, could you point me in that direction until I get my bike dyno'd July 12th? That delta for +6 for flash and headers sounds about right, but I'm a little skeptical on only +3 for a properly tuned PCV (toss out the AT for all intents and purposes if the PCV base map sucks
) and a good pipe (Akra, Leo, None, etc...)
not trying to be a dick, but I might've missed the post of someone who has all the above.
I'm not trying to be a "dick" either, Karson, but Geez, where I saw all that was in those mad plethora of different ECU re-flash threads. I simply wrote the numbers down in my notebook as I read along. I didn't save specific links to specific posts. If memory serves Rasher had some of the numbers from somewhere for part of it, and Jaxon might have had the rest. there were some dyno plots of bikes with Gen 1 flashes and all the headers, slip-on, PC-V, etc. I'm not aware of the specific gains with a Gen 2 flash in conjunction with all the other excess mentioned, but since I talked with Ed extensively about the differences in the two re-flashes I doubt there is much peak horsepower difference between the Gen 1 and Gen 2. Most of the felt difference between the two is apprently in low-speed fueling and throttle butterfly "ramping".
But hey, I thought you were the "expert" here on fuel injection systems, ECU re-flashes, PC-V's, maps, etc., so why ask me?
Again, I'm not trying to be a "dick", but you already know I think hanging all that stuff on a Super Tenere is like Don Quixote tilting at windmills. Chasing one or two HP, or even 5, on this engine, in this chassis, is like trying to add 100 HP to a Nimitz-class Super Carrier. IMHO, getting good, controllable power, and learning to properly use that, is a much more tangible and relevant goal. You'll never see me chasing max HP, and one reason is right here in this thread - I refuse to put a loud aftermarket muffler on my bike, period. If I could get my hands on a Super Tenere Staintune I might go with that, but more for longevity and reliability than anything else. That's why I was reading this thread. In the past I've had Staintune pipes, and they are beautifully made out of premium stainless-steel, require no re-packing over their lifetime, and are usually nearly as quiet as stock. Mated with a set of Arrow headers and you would have an exhaust system that would outlive the rest of the motorcycle and be impervious to any kind of fuel.
I will also say one thing I well and truly believe - that current stock OEM mufflers are incredibly efficient, well designed, wonderful devices, especially for making smooth, controllable power across the rev range. Somebody like "Two Brothers" pulling one of their standard-sized cans of their parts shelf, welding on a feed pipe that mates to a Super Tenere, then putting on a tip that doesn't melt the turn signal... *THEN* advertising it makes more power than stock doesn't convince me much.
I just want to make it clear that I'm not here chasing the same things that you are. My notes say the most anybody has found, complete with all the high-buck gee-gaws, is 9 HP. Maybe somebody's found 10... But I'm skeptical as hell of anybody that claims any more than that, primarily because dynos are so wildly different, and how they are operated is so important. "Seat of the pants" with most riders is so unreliable and prone to all sorts of bias that it doesn't rate much with me, either. There are guys who can tell minute differences in power output, but they have thousands of hours in the saddle, mega-years riding and racing, and even more time wrenching and tuning.
But hey, that's just me... If folks want to go chase 0.5 HP on a 90 HP engine, great. But it's not for me. I do hope we get to ride together one day. I'd really like to see your results on the road.
I sincerely wish you luck.
Dallara
