: Eddy current dynamometer numbers!!!
Fuzy_GSXR1000 05-09-2007, 10:37 AM If anybody is in the NY,NJ, or PA area I seriously letting Tommy Macelli over at Xtreme machines dyno tune your bike!! my beginning numbers were Max BHP 162.41@115.49 & 80.79Ft/Lbs:80.79@84.30 rpm and after he tuned it....well looky...LOL:eek
Pounds of Boost 05-09-2007, 12:53 PM So your somewhere between 151 and 160 at the rear wheel. Man I hate those at the crank numbers......... I guess it looks better in the eyes of the customer from a tuners perspective...
grtfast 05-09-2007, 12:54 PM This is only from tuning? Hard to believe.
Outta Control 05-09-2007, 02:21 PM Eddy Dynos are the most accuarte dyno measurement around if you really want to maximize your available HP throught out the powerband. So looking at those numbers that is some pretty good number based on your environmental conditions you have. :) :punk
grtfast 05-09-2007, 02:23 PM 15 hp from a tune? dang!
shredzs 05-09-2007, 02:27 PM what year is your bike?
what mods do you have done to it?
Throttlestop 05-09-2007, 07:51 PM Did he run the RAM air intake fans during the dyno tune?
grtfast 05-09-2007, 07:53 PM still don't believe 15hp from just a tune.
k6zook1k 05-09-2007, 08:21 PM I feel a little lost here.
The pic shows a bike on a dyno, so how did they get BHP?
Do they remove the back wheel and hook it up to the motor somehow???:scratch
Throttlestop 05-09-2007, 08:53 PM That's rear wheel hp readout he posted.
rraiderr 05-09-2007, 08:59 PM The bike can't be stock.

im thinking the same thing and if it did make those kinda #s whats done to the bike because it aint stock
njfinests 05-09-2007, 09:52 PM Dude those numbers are pretty good.You got a good bike from the factory.My 05 1000 had 161rw/hp.With a Yosh full TRC system,race air filter,velocity stacks and a custom map I had 175rw/hp.So those numbers you have are great!You should have asked him, was that the most rw/hp he has seen on a 1000 close to stock?
What mods do you have???????????
Fuzy_GSXR1000 05-16-2007, 09:55 PM what year is your bike?
what mods do you have done to it?
2006 Idid a yoshi slip,power commander3 and a K&N airfilter thats it.HONIST
Fuzy_GSXR1000 05-16-2007, 09:58 PM Did he run the RAM air intake fans during the dyno tune?
those little things down on the floor that looked like little ac units yes guys i'm new at this and no shit its stock I didn't touch the engine I went to ricky gadson's sportshop before the tune and he didn't bounce it off the rev limiter and it did 158.5 I beat 3 other gixxers before a blue and white one beat my hp record!:D
Fuzy_GSXR1000 05-16-2007, 10:09 PM The bike can't be stock.
It is stock, if i worked the engine it would probably get over 180 backwheel horsepower like some folks on here. who knows maybe its just a freak oh wait SPL has a K5 and his best I believe was 180 to the backwheel So you assholes are gonna say his bike isn't stock either???:scratch actually the guy who did it was more impressed with the 8 foot pound increase he says most gixxers put out this amount. Go do yours with a full system you will get even more pc3 and air filter It took him 3 hours to do this look heres the first run printout ok?
SPL170db 05-16-2007, 11:44 PM Explaination from Jay, one of the managers at Xtreme:
"it seems to me you think ours is high for some reason? When we tune using the brake for step tests the numbers are actual wheel horsepower. When we are just doing sweep tests (which is what all the magazines post and everybody across the nation say when qouting wheel horsepower) we use "dynojet" numbers that we came up with by running a bunch of bikes then comparing them to magazines #'s to use as a multiplier. We did this because people were saying our numbers were too low in the beginning so we went with what everybody else uses when handing out dyno sheets. I am not sure exactly I can check but 170 sweep tests usually equal about 155 or so real Factory Pro Eddy Current Dyno Horsepower."
By "real Factory Pro Eddy Current Dyno Horsepower" he's referring to the typically low numbers that F.P. dynos give because they are actual true horsepower.

"Real" numbers..... are nothing by marketing by Marc.
A dyno is a tool, not some dick waving "I have the big numbers" crap. Most people do not have a clue.
grtfast 05-17-2007, 12:14 PM STILL hard to believe that increase is from tuning the fuel curve...WOW

Man, if that statement doesn't turn reality on it's head. By Dobeck's own admission, DynoJet made up it's numbers. Consequently, those numbers don't read the same bike to bike, or dyno to dyno, making any standarization, reliability, repeatability, or comparability, utterly impossible.
Along comes little ol' Marc Salvisberg at FactoryPro who builds a pure eddy-current dyno with very low inertia, very high speed load control with real-time power measurement, and very high speed 4-gas exhaust gas analyzer, coupled with propriety software interface that a semi-trained monkey could figure out. He decides to not try to emulate DJ's numbers, having found out long ago that they were made up. But his numbers were much lower than DJs numbers. That needed to be explained, so he invented (and trademarked) the name "True Horsepower", defined as power delivered to the drum, minus dyne parasitic drag, corrected to standard atmospheric conditions. The DynoJet Devotees alternate between aloof dismissal and outright hostility.
If you want an example of a successful hard-core marketing effort, look no further than DynoJet's ability to make people believe that power comes from a proper air/fuel ratio - nevermind the fact that what that "proper" value is wanders around like a drunk lookin for his smokes. Or that the crude technology of their 250i dyno, which is little more than their 20 year old 150 with a huge electric retarding device hung on it under a new set of body work, is state of the art. Or that the best way to measure power is not to acutally measure power, but rather to measure the acceleration rate of a 900 pound drum.
So successful is this marketing campaign in fact, that instead of demanding that DynoJet get it's crap together and start making a measuring device that's accurate, repeatable, and comparable dyno to dyno, DynoJet has succeeded in convincing people to excuse the inaccuracy of DJ dynos with an air of sophistication. As long as you remember to say: "well, it has to be the same day on the same dyno - everyone knows that", then you're in the club. Well, Bullcrap. We don't excuse that kind of crap when we use our torque wrenches ("was that Craftsman ft-lbs, or MATCO ft-lbs?") our fasteners ("was that an Ace Hardware M10-8 or a Lowe's M10-8?"), so why in the heck is it so aggressively excused in Dyno Land? It doesn't have to be that way.
rocket rider 05-17-2007, 04:17 PM Reguardless of rear wheel or crank power my k7 put down 6 less hp on the same dyno 10 minutes later. The numbers were 164 for my stock k7 and the zx14 put down 170.
I was supposed to tune mine yesterday now that I have a racefit growler and bmc race filter but weather did not permit.
I will be using a smart card to tune mine because it has more parameters than a pc3. I'm told I should see numbers between mid 170's to low 180's. I'll let you guys know.
grtfast 05-17-2007, 04:46 PM funny how about 2 months ago I started a thread about the difference between dynos and how dynojet reads way high, and people were saying that it was not an interesting topic, but everytime it comes up in one way or another there is massive response, and those who's egos are fueled by a line on a piece of paper with a number next to it flip out when someone states the truth....

Ok...LOl fish so what youre saying is they ALL inflate their numbers? All I know is the bike runs WAY better than it did before he tuned it its smoother at every rpm :)
SPL170db 05-24-2007, 12:06 AM Well, to revisit this issue, and to clarify somewhat. As you can see in my previous post up there the explaination from Jay the manager from Xtreme, the high numbers on the sweep test are a calculation to more or less equate what would be seen on a comparable DJ dyno.......a calculation basically.
So I went back and took a look at the step tests that were done on my bike and checked out the step test for 100% throttle and sure enough the readout shows a max "true HP" of 157 HP and 81 ft/lbs.
So, going back to Factory Pro's website and comparing against some known figures that they have up there (since their recorded "true HP" figures are fairly consistent across varying FP dynos) both my K5 and Fuzy's K6 still seem to still turn pretty strong numbers compared to the samples below.
http://www.factorypro.com/dyno/true1.html
gsxr1000, 05 all stock all stock 136-141 True HP
gsxr1000, 05 race gask, race fuel, exhaust, cams degreed, etc.Michael W. ~ 159 True HP
yzf1000 R1,05 w/ stock exup, slipons, Factory Pro V stacks. 3 samples tested ~145-147 True HP
Hayabusa, 1397cc engine1397cc Wiseco, Web cams, comp exhaust, stock stacks ported, milled head, tuned pc3~ 174.9 True HP
(True hp x 1.15 for DJ hp = ~200 DJ hp)
Ducati 999r, 2005
(several bikes tested) Termi system tuned with a pc3 141-143 True HP
(same as stock gsxr1000 k5!)
RC-51, all years all stock all stock ~ 100-106 True HP
Hayabusa, full system at least 20 samples tested ~ 142 - 148 True HP
60-foot 05-25-2007, 03:24 PM Man thats good stuff. It actually confirms what ive tried to tell people from a common sense point of view. Years ago we used what we like to call seat dyno. That would consist of trying different mods, maps and pulling passes at the dragstrip. The proof is in the e.t. A good friend of mine had his dyno tuned and i never put mine on it. However, he was suppose to have way more hp but the numbers with me riding both bikes was still the same. Thus proving corrections made on the dyno showed on screen hp but did in no way increase real world hp. If the manufactures say a 1000 makes 160hp and people claim to have pipe, pc, and tuning and now have 175hp, why would some of the most known builders sell a head and cam package that would give u 175-185hp.:scratch Just a lil food for thought.
