is it possible to get 117bhp from an fz6?

[Fizzer600]

hi all

recently i have found that there is not quite enough oomph from my 2009 fz6 s2 or rather its always been a bit bogged down on the roll on. maybe it has something to do with me being 108kg but still i would like to get the bike to 117bhp.

reson being i have had the bike a year and i have already put 25,000 miles on the clock so by the time i have finished paying the finance in a years time there is easily going to be 40k on the clock. i wont be able to sell it at a reasonable price and to be honest i dont want too as it is serviced every 6k and and is still really tidy, plus it is the perfect everyday tool and toy.
but i could do with the extra power just to stop me getting bored.
i have already fitted a full leo vince exhaust sytem and new o.e filter every 8k.

would a power commander V plus Autotune net me 10bhp? happy to pretty much go down any route as i wont be selling this bike, will probally end up being a life time project lol:thumbup:

it is possible with head modification to get 120 bhp,one company in Germany is doing that

I must find a link

 

[Fizzer600]

yes please post a link.

as ive said due to the milage i would be lucky to get £900 for the bike and theres no chance i would sell it for that. So im going to be keeping this one.

Without doing some serious engine work, you'll probably never cross the 100 hp threshold with an FZ6 engine unless you're talking horsepower at the crankshaft. As a bone stock bike, the FZ6 puts out around 88-90 hp at the rear wheel.

Without forced induction, there's only so much HP that can be set free with ECU upgrades, and improving the flow on a naturally aspirated engine.

btw, where did you buy your leo vince? in the UK, or did you order it from that italian ebay store?

 

[txlyman]

I'm not exactly sure how the bikes engines handle v.s. the car engines, but I'll throw 2 cents at this.

Since the fz6 is sporting a de-tuned R6 motor, would it be possible to open the head up for more flow while installing the R6 cams that were replaced to detune it? You should be able to tune this bike the same way an R6 would get upgraded except it'll take you a little more effort to "catch up".:thumbup:

Or.. I completely do not understand the bike at all yet and I am way off.

 

[scottsst]

look at it this way you can spend a bunch of money tring to get more power out of an FZ6 that you will never get back in resale. or you can spend that same money on a faster motorcycle!

 

[Fizzer600]

well the bike is 97bhp standard and i thought 100bhp would be easily broken with an leo system which goes from headers back in cluding removal of the CAT & and a PC V. but maybe im missing something.

i was also trying to work out how to reverse enginer the detune from a R6 and maybe meet in the middle at 110bhp or so?

leo vince was and italy job. think you can get them direct now though from leo vince. everyone always asks about the leo vince exhaust are they hard to get in the uk?

 

[Taku]

Manufacturers always state the hp rates rather optimistically..
So usually the actual hp of the bikes is about 5-10 hp lower that it is stated.

P.S. And every machine has different tolerances so there is a little variation in the power output between different similar bikes.

thing is i dont want to spend £5k - 9k on a new motorcycle if £500 - £1000 of parts will sort mine to a level im happy with. as any work will be carried out by me so no labour costs.

reason im looking for 110 - 117 is i tried a friends bike which was 135bhp and to be honest is was a bit to much of a handful to be an everyday commuter bike. and i really only have space for one machine im happy to spend up to £1k on the fz6 to get 117bhp.

worst case is i fit a R6 engine which is probally the easiest route.

found the below part numbers on another forum both r6 and fz6 share a lot of part numbers.

red items different model prefix and part number
blue items different model prefix same part numbers
green same prefix and part number



Interseting points about the FZ6 engine and its donor R6 engine:

So it appears a "5VX" is an FZ6, a "5SL" is an R6 have no idea what a "5EB" is ???

first and for most is this the best way to get HP out of anything is to get the fueling right.I would find a good Dyno service near you and get a PowerComander one your bike. I know with my bike my Dyno guy was able to find 10HP and a 15% increse in fuel milage.

 

[Fizzer600]

Thanks if i got 10hp from aa power commander i would be very happy:rockon:

 

[scottsst]

it all comes down to the guy doing the tuning talk too some of the local racers and ask around to find the best guy.

 

[iSteve]

You need to be careful in bolting on hp. Many hop ups will increase peak hp but at the expense of low end power and toque. A 10 hp increase at the midrange would get you more "roll on oomph" then a 10hp increase at 14Gs.

A larger bike with 135hp like the one you drove could have 20 or 30 more hp then the fz6 at 3000rpm giving you a huge differences in roll on power.

The dyno service and power commander seems like your best bet. And tell the tuner that you want roll on power. 90hp is plenty to keep the fz6 doing 130mph the problem is getting there.

 

[dean owens]

i might have this wrong, but wouldn't more hp make the bike faster? do you need to go faster? i'm wondering if you might not do better to just change out sprockets. no increase in hp but you will get off the line faster and get to the usable power band faster. just a thought.

 

[red06]

i think the fz6 is fast enough for what it is if you need faster i would look into 1000 cc and up

 

[Taku]

If the bike gains more hp it only increases it's acceleration speed..

But if you want to change it's top speed you would also have to change gear ratios and such.

So as an example if you get let's say 15 hp more and change your gearing +1 in the front and -2 in the back it would feel exactly the same as it does now but it would have a slightly higher top speed.

This would only be true if you could hit redline in top gear. You can't because the power isn't great enough to overcome the wind resistance.

You won't hit 117 with £1,000. It would take some serious mods to get there.

So it appears a "5VX" is an FZ6, a "5SL" is an R6 have no idea what a "5EB" is ???

5EB is a 98-01 R6 prefix..

And I would say the cheapest and easiest way too get near 117bhp is to shoehorn an R6 engine into the frame.
Getting 10bhp with a PC IV sounds abit much for a 100bhp bike.
