Ever had your bike dyno'ed?

I have a 1980 gs1100L with pods 140 dynojet mains, and V and H exhaust. The rest is completely stock. The dyno operator said that he had his dyno set on the conservative side too! I think that's pretty damn good for a 26 year old bike!
 
Dyno'ed

Dyno'ed

We made 225 HP to the rear wheel small turbo rides like it has carbs no lag just get's in on . Going around the traffic circle got on the gas leaving the round about spinning the baloney and what do i see a black in white at car cash the blue suit with his book out . He see me smoking the tire i see his lips moving , just shake his head and goes back too writing in his book . Like i said stupid fast . I can't even think how the new sporties that are turbo making 500-600 HP's could be much fun way to much HP's . LOL well you know never to thin and never enough ------ LoL

That is a lot of power. I am not getting quite that much with my drag bike. I am closer to what the Kaptains numbers are with my last setup.

Have a friend who is talking 200 from his Busa drag bike and planning to up it. Too crazy for me.

Bumping an old thread.... :-D

How helpful is it to run your bike on a dyno to get your carb setup taken care of? I'm now running running K&N pods, a Dynojet jet kit, and a V&H 4 into 1, and it needs some tuning work. If setting up the bike on a dyno can get the jetting right throughout the rev range, without a whole bunch of trial and error, it may be worth the $$$. What do you think?

I noticed the current Yosh 1135 Katana pushes out 150 hp wonder if thats at the crank vs my number at the rear wheel?

Must be at the crank. You'd need a MUCH bigger engine to get 150 at the wheel.
It must be about 130-135 at the rear wheel?

My engine builder Rick Stetson at HMP did a great job of getting my bike in the ball park using an exhaust gas anyliser to set it up conservatively (rich) in his shop but he advised me to dyno tune it to make sure it wasn't too lean at higher RPMs. It took the dyno shop about 30 minutes to dial it in. They were able to adjust needles to a leaner position and verify that air/fuel mixture was close to perfect. I was at 111 hp on the first run when I got there and 119 after their adjustments. Of course the skill level of the dyno shop will be key. I think it cost me about $150. Was worth it to me.

I'm pretty sure your right that 150hp would be at the crank for an older GS design @ 1135cc without a turbo. Although I'm not sure I would bet against Yoshimura they may be able to do it.

I would have said that you would need a more "efficient" engine than a bigger engine, since current GSXR750 and 1000s are pushing around 150 / 168 at rear wheel.
 
1st trip to the dyno 8-[

Jeez man, what are you running? Boosted/NOS 'Busa?? :shock::shock:

Sorry, Im not really up on the new bred anymore because I cant physically ride bikes with (broomstick up the ass) seating positions like that....I cant touch the ground!!!
Do they really have 168 at the rear wheel, Surely thats at the Crank?!
Wouldnt they have to be pumping out something like 185-190 at the crank to get 168 at the wheel?!


Anyways, V&H had a GS1100 instructional Video out in the early 80's.
The mods were 33mm Smoothies, V&H (345?) Cams, No mention of porting, 1170 kit, V&H Header & Pipe.
At the gearbox they got 130 @8000rpm, 143 @ 9000, 151 @ 10000.

Im presuming thats around 128hp to 135hp at the rear wheel which is about right based on some of the dyno sheets guys have put on here?

2007 GSXR1000 made 158hp at 12250rpm and 75ft-lb at 10250rpm, both at the rear wheel as published in the June 2007 Motorcyclist.

Motorcyclist dyno'd a 2006 GSXR1K at 159.8hp at 11500rpm and 79.2ft-lb at 9750rpm. Again, both numbers at the wheel.
