All 650's Power Levels!

[Sudesh]

Hey guys so I’ve been seeing a lot of kids in Australia thinking their bike can push 120HP and whatnot. I was wondering what you guys are running exhaust and air filter or any other performance mods and what legitimate numbers the bike is pushing HP wise. Dyno sheets are welcome as proof haha.

I have the 2019 CBR650R with just a casual Mussari Exhaust and the stock air filter and the bike pushing on a dyno 86HP.

Feel free to drop your specs and stats on any model of the 650.

Never heard of a 650cc reach that amount of power
Maybe a very heavy upgrade for race use could squeeze out extra power, maybe 10 or 20hp max, but that’s it
The design of the engine is not meant to go that far unless (again) heavy modified
These mods aren’t even available to us (regular humans), if you can find a race shop where they can customize and rebuild the engine (and spend a lot of money) then it’s a different story, but not worth the investment IMO.
Just the exhaust, air filter and dyno tune won’t give that extra cheese!
Makes more sense to just go after a 600rr if you want that kind of powerband.
Also much easier to find aftermarket engine parts to improve power.

These kids have cbr650r as well?

Oh man this one kid is on a CB650R with a Black Widow exhaust and just a DNA air filter stating he has dyno sheets to prove 100HP.

Another guy stated that he went from a Two Brothers exhaust to an Akra on his CBR650F and was pushing 130HP with a K&N air filter.

It’s crazy in Australia that they think the bike can push that much after just changing the snorkels for US ones and removing the restriction on our bikes to create so much HP 😂

I wanna know how the “godly” mode can be achieved on these bikes
Tell them to stop by to enlighten us 😅

Oh man i never got the story on what he had apart from an akra and air filter because l gave it to his life for the 130HP claim

It’s extremely easy for a dyno to be either purposely or accidentally miscalibrated and have it read higher than “actual” numbers. You’ll see this on the mobile dynos quite often or on shops purposely trying to impress people and in the end it means nothing because it’s a simple lie.

There is literally a field in the software you normally leave as a constant or make little adjustments too that factors in weather, your location in the atmosphere, how your inertia is set and where all your sensors read that is supposed to then give you the “accurate” reading. You can always tell a poor shop because they brag about how high their numbers are, or how much power people make at their dyno. My good friend works for a company that makes all sorts of dynos, I have been there as he sets up the software, then sets the calibration numbers and have seen graphs of incorrect correction factors that show his 600RR making 250 hp where it actually makes around 100 or a beater LS1 shows 140hp until everything is setup and it’s back to the 300hp range.

What you want is a before mod and after mod graph, and you want to use your head with what makes sense: Honda outright says the 650 is built as a 97hp at the engine, if they are showing 130hp at the rear wheel that’s more than 40% more than factory and the engine design just will not make that kind of power. It’s bullshit and they know it. My old 954 made 126hp on a local dyno I trusted but at a bike night in Tennessee or Georgia (can’t remember where it was) in the mid 2000s they said it made like 138hp which I knew was BS because that bike was beat before I bought it and had a weak output.

@Sudesh your 86rwhp is about perfect for this bike. We’ve not seen many dyno graphs for some reason around here.

120 hp out of a bike that is rated at 94 hp from the factory? It's possible, but would take a lot of work. It would be way easier to just sell the 650 and get the bike you want instead. It would be far easier and probably cheaper to just get the CBR600 or CBR1000 that you wanted rather than modifying a 650 to make significantly more power.

To get up to 120 hp, I think an engine swap from a wrecked bike would be the easiest way. IIRC the 650 is basically a bored out 600, so the engines should be reasonable to swap. Don't quote me on that though. I may be way off base there. Other than a swap, you'd have to rebuild the engine with beefier internals. Valve springs probably can't handle any more RPM. New cam shafts will help get more fuel and air into the cylinders. Intake would need revisions to get better air flow. Then that air has to go somewhere, so new headers and exhaust are probably necessary as well. There's just too many bottlenecks trying to get that much HP out of a 650.

If you're getting 86 hp at the rear wheel, you are doing good. If someone else is claiming 120 at the rear wheel, they are most likely lying. If they aren't lying, they've done an engine swap with a 600 and tuned it up a bit. 120 at the wheel is impressive even for a 600.

Don’t forget the goddamn computer. Nothing swaps easily any more with everything plugged into and controlled by the goddamn computer. Even modding the existing hardware, especially to the degree these squids are claiming, can’t be done without some serious software mods. I’m having a hard time buying it. And if somehow these guys did achieve anything close to what they’re claiming, I’d have to think it cost them a whole lot more money and time than just buying something off the shelf with those kinds of numbers. They’re either lying or stupid or both.

Turbos, maybe?!

 

[volkein]

This is the way.

 

[Sudesh]

Oh yeah you guys don’t have to tell me his mechanics full of it and that he’s just some kid that has no idea they can lie to him. Also l can guarantee it’s not a swapped engine at all since it looks identical to my old 650.

 

[Fezbruv]

Yeah I got 95Hp out of mine with Power commander, exhaust and filter.

I seen the post you were talking about and i was like this guy must have a smooth brain.

I have the Naked version but everything is the same i got mine done in Sydney.

This may be a stupid question, but did you have to have the ECU remapped as well as install the power commander, or is that with the power commander alone?
Thanks

 

[JH09]

over 100hp at the wheel? must be a LOT of stickers...LOL 😂

 

[Brammers]

Short of serious mods and/or custom fuel, anything much over 90 at the wheel on the 650 plant is either (IMHO):
a) a badly calibrated dyno
b) lies

I've got 89 and a smidge on standard UK spec 95 RON unleaded (unsure on ethanol content - 5% I think).

Using 98 RON (mostly because it's 0% ethanol) fuel will get a small gain on that. Tyres can alter readings too BTW.

D @Dizzy - PC takes care of it. No need for additional ECU mapping unless you want a tuner to put in a custom tune that is not provided by PC.

A liar in our midst!

Claiming 95 when the sheet clearly shows below that!

😁

 

[NUTSACK]

I hollowed out my intake funnels,DNA filter,Akro exhaust,custom Dyno tune and netted 86rwhp And 45nm. It started with 49 rwhp and 33 nm so it’s a solid gain and so much more fun to ride now..
I know Dynos will all vary a little and so many things can vary the result but anyone claiming much over 90rwhp are getting taken for a ride by the person doing the work or they are just full of sh.it..
ive seen and heard it all before when the LS engines first came to Australia in our commodores..

 

[JH09]

yeah, from 49 to 86hp must feel like a different bike! how do you like the akra? wondering about pulling the trigger...thx

 

[volkein]

Something's wrong, you should get like 63nm.
