Ive seen HP #'s between 100 - 120 HP. I think torque as similar at 110 - 120 ft / lbs.

Then I might be totally off base.

Anyone else?

Another round please
I remember reading 90-100 stock, 110-120 with pipes, jetting and a K&N.
You need much more than that to get 120 hp. It sounds good to say I have a bunch of HP, but the reality is alot of guys pump it up to sound good. The 08 Harley 96 inch streetglide for instance has 62. If you get 1 hp per inch, your doing awesome. I dyno'd at 114 hp, but took some good cash to get there.

If the 08 are getting that amount of horsepower, I am pretty sure that it is not at the wheels. Maybe one of those situation where it is listed for Engine HP like many vehicle which does not coorelate to Rear Wheel HP.

The numbers that seem to have been posted on here for pretty much stock as well as on other sites and articles seems to be around the low to mid 90's for stock with decent pipes.

It would be nice if someone from the puppy farm would let it slip out even as an Anonymous poster from an off site PC (hint hint hint). :up:

I would agree 110 but not at the wheels -- speaking of wheels that is where we lose power, the heaver the tire/wheel the more it takes to turn it - guess thats why most scoots have smaller tires -- but I still love my 300mm!!

2005 117 was in the mid 70's for HP. They sucked.

I would say the 2007 are between 90-100 HP stock and not over.

Raywood had his bike dyno'd.

stock motor with pipes and air cleaner upgrades. stage 1
Here is my dyno sheet from years ago. Remember this is the 05 that came out with an E carb vice the G for all other models plus the motor has smaller valves. For this run I had on that worthless Wimmer Ultra Sucker (that didn't suck much). I had it done again last year but don't have the sheet and it was 98/112 hp/tq.

Don't believe that 70 hp crap people try to spread about the 05's!!!
This run was done in Laughlin or Vegas, can't remember which!!

2006 stock dynoed 95hp and 110 tq.
2006 jetted with k&n and pipes 113hp and 120tq.
2006 jetted with k&n and stock pipes drilled 108hp. and 125tq.

These are DynoJet Numbers at the rear tire.

ajo,

Not sure which dyno you are asking about, but if it is Ray's, it at the rear wheel. For that matter most any sheet that will be posted here will be a wheels unless it is for a shop or manfacturer. If it is a DynoJet run, almost gurantee that it is on a roller dyno measuring the rear wheel (actually most case it is measuring the power it takes to spin the fixed roller mass and how fast and this is coorelated to the rear wheel that is turning that roller).

My 07 117 with a K&N and the stock pipes drilled out and unjetted showed 106 HP and 112 TQ but they didn't say wether or not it was at the engine or rear wheel. But I thought the dyno always showed at the rear wheel. Of course I could definitely be wrong about that. According to the guys at Big Dog, they said that the 07 117's with the all S&S valve train are all ready set up to be unleashed if you just change the cam and install a Crane Hi-4 ignition set up. For Now I have ordered a jet kit from Nelson and when it arrives I am going to install it and have it re-dyno'd again when I get back from Myrtle beach.

Seems to me when I was researching Big Dog before I bought one I had seen 119 hp and 112 ft/lbs stock. I've been looking for the source, but haven't found it yet.

Any DATA I've seen seems to be lower, I suspect because of engine spec vs at rear wheel ratings.

AJO, I'm thinking that some of the differences in readings might be the quality of the operator. I've been told there are some that are very sharp on a dyno and some that are not so sharp. I wonder how true that is. The guy that did mine is known around here as pretty damn sharp on the dyno.

The numbers I mentioned where marketing claims I sure, which means some sort of spin to get the highest numbers.

The most consistent info seems to put HP in the 100 to 110 range, and the TQ in the 110 to 115 range. This info come from mostly private dyno test on private bikes so I don't know if they are stock or not.

Ajo,

I would not be unusal to see posted HP/Tq numbers from the maker, and normally such numbers are always related to BHP (Brake HP or at the engine using a brake dyno). What we see at the wheel will be much lower and is what 99.9% of the sheets for dyno run would be showing. Also if you put it on a set of rollers with the wheel from mc turning, there is no true way to get the Engine HP-in case one tries to convince the customer they can do a direct conversion.

This is one of the reason that the maker will test the engine on a brake dyno to set their standards, for that is a pretty consistent factor, however what occurs with the many factors between the engine and the road varies too much to give a nice straight factor. Thus the roller or wheel dyno.

If I build engines, I will put the engine on the brake dyno and get a complete sheet for that engine, thus the customer knows that they have a consistent base to work everything else from. If one buys a crate engine say from GM and it is listed at 500 BHP, you can pretty much put the sucker on a engine dyno and get consistent run (within a very small +/- factor) even with a different motor (same build) as long as all the other parameters remain the same (oil, build, enviroment, intake, pipes, etc). but you put those engine in matching vehicle and you will get different HP and a much higher spread due to parasistic drags, and others.

Things like oil in tranny, primary, tension on chains, belts, clutch slippage, tire pressure, bearing drag, wheel mass, gear tolerence, etc.

Not that it really applies here, but I will give you an example. I used to race bicycles (at upper levels, including International). During that phase of my life, I was able to do some intense testing and measurements, one thing that made a difference was the type of bearings we would use for the wheels and bottom bracket, as well as the rolling masses of everything from the wheel to the crank and bottom bracket.

Most would not think much of this, unless you peddle such over a few hundred miles for a few days. In that case what little difference between a steel crank axle compared to a Titanium would or between even down to if you used a ABEC 5 Bearing verse a ABEC 8 or 9 would be a factor and too many worth the higher cost. The same would be for the tires and one of the major reason that many use true tubular tires to much higher pressure (I would typically run tubular with 160 PSI in them for racing)

In my case allot of stupid money on nothing but Campagnolo Groupo that did not make me any better per say, but left any questions out on my componets. People think motorcycles can eat up some money, get into serious bicycle road racing and you will really be shocked considering it is a bicycle.
