BEEN TO THE DYNO
 

Hi all.
Well finnaly Got the lil beastie on the dyno today. A few of you have PM`d and asked if the advancing of the cams were worth it.......The answer is yes and no.
We did 28 runs this morning to get the fueling spot on, which was still set up for the BB kit. With the kit we were getting 49bhp And todays best run on 583 cyls was 1 bhp more:sing:
The midrange is still very good but the bike is now reving and holding on to its power curve to a scary10500rpm:o:o
I was Cacking me pants at first but it seems very happy up there. Last year it dropped off the end of the world at 8500rpm.
So was it worth it ?? Dunno yet has to be the answer, I will have to ride it I suppose., Im happy with the result And i will be even happier if it lasts as season reving it to 10.5K....:lol: And if not Skids is bound to have a spare engine under the sink.
So in conclusion, If you have 52 bhp and i beat you Im having your engine, Second amendment to rule 36b, (wasting BHP):sing:
Will post giraff Later
Glyn

LOL.......

souns like its all systems go Glynn:D

Yea its been too long:(
But getting closer:D

Have you not bypassed the rev limiter, then?

:burn:

If you can hold onto power for longer even though you're not delivering any more then it means you have a measure of increased flexibility. An ability to rev longer can mean less gear changes and lower gearing for better acceleration.

As a matter of interest, seeing as power is a function of torque and engine speed, what is the torque compared to before?

Do 583's have rev limiters? I wish I could dispense with the limiter on my 800ss - that really is holding back the motor from producing more - as it is the limiter is brutal and kicks in bang on 8900 so, what I've managed to do is increase mid-range power and torque instead.

No limiter on mine:burn:
Well there is I think its when the rods stretch and hit the heads, but I aint got that far yet:lol:
Torque has remained pretty much as it was, i think my BB kit was set up by a muppet tho to be honest, As skids can confirm his 583 last year was pulling away from me down the caddy back straight, Which aint right.
Nige cant the powercomanders up the limiter?? or are they just fueling on your bike?
Im sure its possible Just finding out how isnt it.
glyn

Mate my ass was the limiter.... When it got to 5p diameter i shut the throttle.:lol:

The PC is just doing the fuelling Scoots. An FIM Ultimap ECU is the answer of course but, as mentioned elsewhere here, it's not permitted under Minitwin rules. I'm looking forward to getting the PC though as with with the filter, pipes and the PC I'm expecting to break the 80bhp barrier.

wow that revs hard my power drops off 9500 rpm but iv got 52BHP at the rear wheel. ill see you on the track

I'll have 63bhp... you won't be seeing me :lol:

:lol:

I think we'll all be watching your results and times with interest young whippersnapper!

:lol:

I bet he hopes not too:P

cos:

1. you aint planning on playing on a 620 in the 583 class - are you? :puzzled:
2. We have more than 63hp:lol: (just!:o )


C:D

so how have you got the power to hang on to 10500 rpm

Where else am I supposed to race it? :devil:


I'm only guessing. It could be 68 :o

He's obviously broke it :eureka:

well if not it soon will be have to catch the ****tons when it goes

I know a song about that...

"Ali broke his engine at Brands Hatch,
Ali broke his biiiiiike at Brands Hatch,
Ali broke his bike at Brands Hatch,
Oh dear oh dear oh dear"

:lol::lol::lol::lol::lol::lol:

Advance the cam's with a 180 degree offset woodruff key :)

£15 each from JHP

Dom
Not Quite like Kye says , but yea By dialing in the cams to a figure easilly obtainable from the net. You may have 52 bhp but I would guess its all up the top end, Retarding the cams will give you a top end rush that makes you think the bike is quick, What if:eureka: you could have that punch throughout the entire rev range..
:saint::smug:

Then you'd not be on a 583 :lol::lol::lol::lol:

Oy geek this is a 583 discussion for 583 people, We`ll Have no 620s here, And dont touch the precious things....

That was harsh :sniff::sniff::sniff:

I bet that nasty Kirsty fella has signed in as Glyn by mishtake :o

Oops your gunna get it now, she is removing her laptop from its holster....:o

:saint::saint::saint::saint::saint::saint::saint:: saint::saint::saint:

nasty Kirsty fella signing in.
Dom I would never sign in as glyn.:P

Has he been telling on me again :smug:

How's my favorite scooterbabe today? :D

Just shut up Dom - he was just going to tell us what he's done to the wee beastie when you distracted him :mad:

scooterbabe is fine
thanks for being so niceas to ask.

Would like your opion,
thinking of sprying my monster dark a lovely girly colour PINK:bouncy:

Come on then, spill it all :roll:

I have no secrets, i will tell you all. Its quite simple really, you do have to remove the engine from the frame to do it and its a bit of a struggle but once the front cylinger is put on the back and vice versa the bike will run like a dream..........:frog:

Well Glyn I will see if its a improvement on the 675 as my 583 is untouched from when I picked up the engine from the breakers apart from a couple of Oil and filter changes.
If you come sailing past me on Park Straight I'll be impressed :o

Pink is fanstatic darling, you'll be the new DD diva :lol:

I was gunna go on about big pink throbbing things between your legs, but I best not go there :o

;)

I'm guessing that could be wholey possible at Cadwell in March!!

Wets anyone?? :lol:

Great idea Kev, I never thought of fitting sails....wohooo off to garage with bed sheets........... Later:eureka:

Me too:

"I broke my engine at Brands Hatch,
I broke my biiiiiike at Brands Hatch,
I broke my bike at Brands Hatch,
But when it was running I handed Dom his arse on a plate more times than I can remember"

:lol::lol::lol::lol::lol::lol:

Sorry, that last line needs a bit of work!:lol:

Big pink throbbing things are a girls best friend(not Diamonds),LOL:lol::lol::lol::lol:

:lol::lol::lol::lol::lol:

Has everyone been drinking? :lol::lol::lol:
