DYNO CHART 1507's streetbikes

[FASBUS]

 Which one would you rather or think would be faster ? Checkout average hp/torque thru rpm's..

[glenn71]

The blue one,although i,m green seeing that from a streetbike.

First I'd get the chart printed properly, which means corrected. You can't accurately compare those runs uncorrected, 4 years apart and different conditions on each day.

TRU DAT...
It is truly hilarious and sad at the same time that we continully see dyno charts  like this. There are enuff differences in the weather conditions that will have big influences on power, so these runs should be shown in the SAE cf for some legitamcy.
The conditions are good enuff that the skoots are running in the equivalent of below sea level conditions, so SAE numbers will be lower, not necessarily what some dyno shops want to show.
Big numbers = happy paying customers.

  Im glad I could give you some ammusement this morning Ray...
My whole point in posting was to bring to attention that everyone ALWAYS refers to peak numbers which is not always the fastest/best..
 Im not posting to show anyone I can build power because I know I can & really dont give a shit who thinks its sad...
 I also know that dynojets corrections factors leave alot to be desired & corrected #'s wont coincide either. In order to truly test apples against apples you need to  run/tune on the same day/time..
  The dyno I tune on which has tuninglink in always on the low side & at least 10hp down on other local dynos & if I was trying to blow smoke up anyones ass I
would post those charts after all all the information/weather conditions are right there for you to read so I would appreciate any sad comments be left to one's self..
 Thanks...

 Not to mention the 230hp was out of injector/fuel & a/f was out of control on the big end....

It's funny and sad at the same time when someone tells someone else to keep their comments to themselves. You are free to post dyno charts that make it impossible for those of us "in the know" (cause we ARE gonna look at the run conditions) to try to make sense of the power figures and to answer your question.
Yea...the c/factors do have gaps in them but they are FAR more accurate than uncorrected. We ARE gonna analize all of the data you provide, and dyno graphs in corrected form were requested in a previous post. Post these runs in a corrected form, please?

THANX

FASBUS, good numbers. Get some more fuel to that baby and let us know what happens.

.... Its being reconfigured to 1535 w/oversized valves & larger camshafts,will post results..

Dude its funny & sad how much of a joke & a hater you are...Do us both a favor a never post on a thread of mine , my only point was peak numbers arent the end all. I bet your mother has told you before if you dont have anything positive to say say nothing at all. Internet pissing matches are for pussies & not my style so PLEASE stay off my thread..

I see youre point however other than the time distance apart the conditions of the two do offset each other..I was posting to show the difference of peak power as opposed to average power. No matter what the peak values are was not the point. I appreciate youre subjective opinion with out insult......
 

[glenn71]

Those run conditions are entirely real world for a before lunch pass in autumn or spring over here in Australia.15-20c with low
humidity on a sticky track at 30+ air pressure and the bike will fly.You dont sae correct your drag strip numbers on a good day or a bad day or do you ignore how it flys on a cold night,preferring to only ride in the heat of the day?It clearly states
UNCORRECTED.If the dynos in an area with air that cant be duplicated at
peoples local strip,fair enough,sae numbers would help and allow comparison
to other peoples results on their dynos in lesser air,but,the run conditions are there,so punch them into an sae correction calculator and you can see how it would
run in the air on someone elses dyno or known air quality at your local strip?Average hp beats peak hp every time.

Well, what numbers did each run at the track and at what weight?

 ....... Dont forget to calculate in the 20mph headwind..

I thought that was a joke..Bikes were setup for top end .Glenn71 was making a point w/dragrace reference...

[glenn71]

Horsepower calculators work quite well ive found.Your mph at a given weight can reveal very close to and sometimes a slightly greater horsepower number than an honest dyno reads.Ive used them for a while and can indicate how much power a bike can pick up in good air.At 685lbs i bested 158.6mph which worked out around 212hp for my 1441 which is almost exactly what i got.

[FASBUS]

 Oh yeah these were with pump gas also.......

I would be much more interested if it was a thread about a 1507 that could live on the street and take a hard ass beating and was reliable. I think the only 1507 I have ever read about was dave owens bike and it only had 5K miles on the build at the time I believe. Anyway it would be pretty awesome to have streetable 230-250HP pump gas all motor busas if possible

 I considered Dave a friend & very knowledgeable engine builder that shared trade secrets on building streetable/reliable stroker engines on many occasions. You dont have to assume that all stroker engines are not reliable because thats not always the case. My engines have lasted & proven themselves , however even Daves engine was torn down & gone through to freshen up bearings etc after so many run/miles. It is possible to have reliability w/routine maintenence...

 All good brother Im not that insecure....

My reference to Steve was not meant as disrespect to you.  The only reason I mentioned him is that he use to work for Carpenter before starting his own operation and have built hundreds of strokers over the years with results most board members are familiar with.  There are very few builders that have as much experience with strokers as he does.

Yeah I understand that it can be done. Just not sure how I would feel about having to pay someone to remove and freshen up the engine every X amount of miles. Guess that's why I have a turbo.... But all motor is cool I think

[FASBUS]

  Whether turbo or all motor you need to do some scheduled maintenence..I actually prefer all motor over turbo for longevity , I know quite a few people that got away from turbos because of melted pistons & other issues.Motor big cams,high compression are worst longevity issues..Turbo,nice low compression crusing,small cams however lots of other engine management going on than factory ecu,injectors,pump.. As soon as something goes aray & you loose fuel or detonate from to much cylinder pressure ,boom your done...I believe above everything else you need to set your shit up right whether turbo or motor & youll have a chance...
  I love a 380hp turbo on pump gas....   But ya gotta remember there are only two kinds of motors out there, ones that have blown up & ones that are gonna blow up...            i.m.h.o
