Though in this instance it doesn't make a great deal of odds; 5% of 152 = 7.6. so a 0.4bhp reduction.
Installing a Rapidbike unit would yield better results and much easier than finding a unicorn (Termi upmap)
“overstate performance and understate weights.” My Mrs has been saying I’ve been overstating my performance & understating my weight for years too!
You'll be lucky to see 130 at the rear wheel and maybe +5 mid-range gain. $2000 / 5 = $400 per HP. Now there are other valid reasons to get rid of the CAT, to cure engine de-cel snuff outs and to get rid of foot heat for hot countries. As regards the title, adding a slip-on is only for sound and looks.
thought I'd google chassis dyno and the difference with engine dyno. Ot makes no sense to me why the chassis one would be higher, as thats a rilling road ie rwhp?! Is it because is allows the affect of air where the engine doesn't ? Link to article. https://www.enginebuildermag.com/2019/10/chassis-vs-engine-dyno/
Im pleased to report that my 1260 pulled a 141 HP dyno run from a Ducati claimed 158HP. 11% to 12% depending on the Dyno smoothing factor used. More importantly for you 1200dvt guys, my buddy's 1200 with a Rapidbike and stock otherwise also pulled a 140HP on the same Dyno an hour apart.
I really DON'T care! This data is only relevant when you are leaning against a bar with a pint in your hand, trying to play "rear wheel BHP top trumps" alongside those who love to chat about such trivia Apologies in advance for using the recently dismissed half-wit's name in vain here and for the disallowed activity description, at least here in the UK, of actually being in a bar, let alone drinking All I need to know, is that when I twist my 1260S's throttle, it goes like stink, whatever BHP it has or indeed might have mis-laid between the crank and rear wheel.
Well.... all I know is my bike’s faster cos’ it’s white.! That’s why they say “ Like White lightning.”
There are also two common types of chassis dyno...Inertia (weight rollers) and hydraulic (fluid resistance)...a 140 pull on a inertia maybe 130 on a hydraulic. https://www.hotrod.com/articles/hrdp-0405-chassis-dyno-guide/ Same car...
I think our bikes were a bit faster than those Germans we stumbled across enroute to an EMM lunch stop a couple of years ago - how many did we overtake on the way up that pass ?
Nah, come on Sh' you know that's patently wrong....It's always RED. ADMIT it! Look, even the only avatar/smiley on here is red I rest my case.
Which is the regular down the shop dyno then? That’s on rollers but you’d expect to be the lowest number. Sounds like there are different types of roller ones?
Very interesting. Most MotoMags use Dynajet and the proper smoothing correction factor is SAE. Although not perfect, a Dyno is the only way to show if a mod is actually improving performance.
