My '07 made 163 first time and later 171. All stock with 230 miles. Still stock. :D

Funny?
How so?
I rode it too slowly and the secondaries got "Stuck" and were slow to open.
I include a Dyno Chart.

Ever hear of HAPPY dyno?
FUNNAY.... :lol:
Looks like 168 not 171.
PS - you don;t get 6rwhp if you didn't at least add PC3 - then it isn't stock... :thumb:
You also won;t see that when you are riding in 90 degree heat in the summer either since it was done in a 65 degree room... :wink:
-
Weeeel, it appears my scanner is not as good my bike nor is the operator of said scanner.
It seems to have cut off the last run.
Happy Dyno? No, Not yet.
But it had only 1 mile when I got it from the dealer and now has 425 miles. No PCIII or anything else. Still gots the stock potatos and Cat under the swinger and reminds me it's still there by roasting my thighs whenever I ride it.
I'll try to fix the scanning and pop up another, more legible sheet, hopefully.
And yes, 90 degrees outside will kill a bunch power. But doesn't matter as I still don't open the throttle past halfway. :?

Whatever. We have seen many happy dyno's and your numbers don't add up.
Also how did the ambient temp drop 5 degrees in 10 minutes?
It just doesn't add up NOR seem normal (or even close)...
-
While I can honestly say there was no dyno tweaking at the time, I can't explain the rest. Maybe it was a very happy dyno?
:shock:

Gnd,
Dyno is about avg..air density/quality was very good. The first pull it actually broke up a little...the owner had ridden it very conservatively during breakin...
All I did was clean out the carbon...and heat cycle it a bit to breakin. Then every successive pull it made more power as the rings set in....
Pump gas stock bike good air.....the owner works in our machine shop on cylinder heads..I did as a favor on a Sat...
Hows ur bike runnin??

Pretty amazing. Not here to argue with you Dave since you are an expert. 170's 100% stock is just amazing considering the 14's and Busa's are barely cracking that in their new forms.
As far as my bike - it will be on the track in about 2 weeks and hopefully will go to Maxton late this year... :thumb:
-
One thing to remember is that a 1000's torque is low. It makes the HP by revving high and maintaining that low torque. If a busa could rev higher and maintain a decent torque it would make higher HP numbers too.

BQ - true to a point. The Gen 2 Busa in stock form makes peak RWHP at 9650rpm and does not hit the limiter till (not positive) 11,200 so even with 12.5 c/r and more aggressive cams it is not producing much more HP that the G1K with 340cc more. Best bang for the buck looks like the G1K even after all the updates...
-
Gnd,
I agree its impressive....I was getting low low 160's with 05/06 1Ks stock.. So almost 10rwhp...but the air was very good.
FWIW just dynod 01 1K pipe U4 2 intakes ...made 158rwhp sae.
BTW I am not an expert on anything...I just learn from my experiences.....
08 Busa w pipe PCUSB and U4 made 201rwhp sae....all else stock.
Dave

DaveO - yes you are an expert. Your accomplishments and integrity prove it. :thumb:
-
Dave O, What did a stock 08 busa or zx14 run on your dyno?
-
08 Busa Brock pipe, pump gas, no PCUSB made 196 when I dynod it....11 miles on it...in 5th gear.
Dave

Dave's the MAN!!...............and modest too!!!!

...Best bang for the buck looks like the G1K even after all the updates...
GSXR1000's absolutely are the best bang for the buck and without all the excess weight. With the current performance of the GSXR1000, I'd never consider another Hayabusa purchase. Busa's are just additional weight to accelerate and slow. I'll keep my 99 Hayabusa and 01 GSXR1000, as they both run fantastic and I made a lot of performance improvements on my Hayabusa, so it's far better than stock, but I am gravitating toward a 2008 GSXR1000 purchase. :thumb:

:lol: ... yeah, new Busas are just slow ass POSs. :duh: :lol:
-
Q,
The 08's are bad azz....200rwhp with just a pipe and MR9 is amazing.....Their HP vs CC ratio NOW finally rivals the 1K's...We just did a 3mm bore/head/cams on an 08 and it made 235rwhp SAE on pump....and ~130ft/lbs of torque!!!! Thats impressive!!!!
Besides I find the Busa much more comfortable than the 1K's...and I am a BIG fan of the 05 and newer 1K's.....Having built/tuned/and won championships with them 2 out of 3 years in a row...Lee ONLY managed 2nd place this year....LOL
Dave
-
Dave,
why do you think the 08 is making so much more power these days...I mean a +3 in the bore is 1441 and 235sae is about where the 1507's were a few years ago and that's not on PUMP?
-
Suzuki built a better bullet. Improved electronics and fuel delivery with the new Busa. Better head also. :thumb:
-
I rode the '08 Busa yesterday, and I have to disagree. I just sold my '06 liter bike, and had planned to buy an '08 liter bike. There is more to a bike than peak horsepower. The Busa's torque is very impressive, and makes the bike a blast to ride. It's also more comfortable than a liter bike . I'm buying a new Busa and I won't be going back to the liter bikes. On the street, torque is king. BTW, I'm taking 35 pounds off my Busa with a full Yoshi exhaust system.

Tyre slip. If you can get hold of the runfiles and email them to me i will repost the graph showing why the power is moving around. This often happens, look at runs posted and you will get runfile001 or 003 as base reading. There is no heat in dyno or tyre/bike. Then it gets mapped and heyho, a nice big 7bhp gain. Its all down to temperatures and slip. If you map a pc3 and show a 7bhp gain then immediately zero the map and run again at say run 40 after an hour of mapping you will see what i mean. Like 7bhp gain now becomes 1bhp gain.
-
And yes the numbers seem very happy for a stock bike.
I'm just doing some headwork on a k7 motor today and base reading was 171bhp with a full system and em-pro fully mapped on a 16.5" ntec dunlop slick. So perhaps 174 on a hard road tyre. Stock are normally around 165.

You are correct...stock is around 165-168 SAE on OUR dyno....I have had several break 170rwhp on SAE with GOOD air...The air density correction on the 250's are not perfect....
Gregs 1K was not a tune...just a dyno breakin...that I kept heat cycling and it responded as usual for a bike with 100 miles babied...To get his "best" numbers I ran the bike and warmed it, then cooled slightly to run it at it's OPTIMUM engine temp(where all the newer 1k's make best power, which I am SURE YOU KNOW), then made sure tire was warm/strapped....
Its always a HAPPY dyno when others cant get the same results.....I finished dynojet school two weeks ago...LOL
PM me if you want to discuss this further....171 with headwork and EM pro is a little low...esp if you raised compression on it. Our SS bikes usually made around 185SAE rwhp on pump WITHOUT EMPROs...they were banned in AMA Prostar in 07...So I had to use my extended ECU's and other trix....since the PCUSB's set FI's above 180rwhp.

At least you know how to run a dyno, more than can be said for some :?
Base reading was 171bhp. Not tuned :thumb: I used stock cams on this one pulled 185 with 87 torque. Epoxied head, no welding of ex ports or chambers on this one. Stock headers too which work good. Had a full yosh spec (str cams, cotters, retainers) with wisecos and carillos in few weeks before and on same tyre that pulled 181 with 81 torque so my headwork sure isn't lacking.
Yes the dynojet correction is not perfect. I was seeing SAE correction of 0.92 :!: Uncorrected it was mid 190's.
Figures i was quoting were in STD correction. The stock motor with this half system and em-pro was 167 SAE. A stock motor is around 158-161 SAE here.

The hater's never stop.... Good #"s bro, now travel the u.s looking for "real" dyno #'s and get back to us..... Once we approve of the #'s.. ONly then will you be able to have a valid post...

We approve? Valid post?
I do not understand what you are saying, maybe i read it too fast .....
-
At the end of the day, the #'s really don't mean much. The air/fuel ratio and the mph at the strip tells the tale. Nice bike, they're fun! Go ride.
-
Man, what a can of worms were opened upon this post. I had no Idea. DaveO is the greatest and did me a big favor by dynoing my new bike. Now, I wonder is he can sneak in another run to see if the slip-on did anything to help or hurt my power and torque. And see what the A/F became. Though, when i get around to putting aturbo system on it, He will be the one to Tune it for me.
And yes, it's not so torquey as the Busa and a little more difficult to ride because of that but it still goes well and nearly 100 mph in first so I can't complain. Though I will go halfway and hope to find a Busa engine to wedge into :lol:my old '83 Katana.
All I can is THANKS DAVE O!

i think for my age an litre bike is better only because i can ride in that position for a long long time. busa's are more comfy but these days between the litre bikes and busa'a and 14's its the rider. a slip on either side and u loose the race. either way i would like a busa just to cruise with i have a gsxr 1000 01 and a 08 zx10r love them both but not comfy for 2 ppl at all

Comfy is important , my missus loves the comfort and the speed !
The faster I ride the better the sex is when I get home ..... alls good ! :thumb:
