dyno
- Thread starter whzyrd
- Start date
i agree i thought it was a lil much also but i then took it to one of our other dynos next door and it ran the same numbers within 2 hp we have 3 dynos on campus and the 2 i ran it on are about 6 months old we are a training center for dyno jet if you buy a dyno dyno jet will send you to us to get trained or we send someone to your dealer to show you all the bells and whistles and the best news is we are setting up our new tuning link in the next 2 weeks

what type of dyno

does altitude effect dyno #'s ? even with or without a PCIII. i was thinkin about getting mine done in farmington, nm (5,500ft)...i dont think flagstaff (7,000ft) has a dyno...maybe i should haul it to phx to get it on your dyno..wow.
Does it affect dyno numbers... dude, I am surprised you had to ask...
Of course. At 5500 ( I am in Denver at the same or much higher at times.) you can expect to loose at LEAST 10-20% on the dyno. The dynos at this altitude are "corrected" for altitude to give you accurate numbers(HP measured at sea level) but that doesn't change the fact that you are still down 10-20% in HP at these altitudes and there is nothing you can do about it, but mod up to compensate...

well thats what i was thinking...but wasnt sure if the PCIII that u have is able to adjust the lean mixture for the altitude enough to bring the performance back that you would normally lose...or at least partially

by the way where was it that u had it dyno'd at and how much did it cost ya?
ok this is for johnny we run the dyno jet 250 and the 250 I. All 3 have eddy current brakes. it didnt cost me anything to run on dyno i am a chief instructor at motorcycle mechanics institute and i ride an 03 silver and grey Busa dont cruse mill but i will be going to pavillions tomarrow night around 8 ish
and i live in chandler and commute to deer valley every day
thanks for all the replies

what was uncorrected (there is a reason for asking)
Johnnycheese

not really less if it was in an encloesd room with A/C uncorrected will be more than corrected
Johnnycheese

then I will put money on it that it is in STD not SAE
Johnnycheese
Registered
there is
STD
SAE
Uncorrected
DIN and one other one (don't feel like turning on the dyno)
Uncorrected is just that what it make right then and there.
(this is what I use due to DYNOJET's weather station is a real P>O>S>)
then I correct it to SAE using real temp humidity barometic pressure and alt.
If I use the dyno I put it in STD and correct the alt. to 1400 feet (I am at 670) and it still reads 2-4 lower than SAE.
So my sheets say STD but the customer knows what they really have.
For the SAE J1349 relative horsepower calculations, the standard reference conditions are: Air temp 77 deg F (25 deg C), 29.235 Inches- Hg (990 mb) actual pressure and 0% relative humidity.
for STD
The density altitude is the altitude in dry air that would have the same density as the input conditions. The ICAO standard conditions for zero density altitude are 0 meters altitude, 15 deg C (59 deg F) air temp, 1013.25 mb (29.921 in-Hg) pressure and 0 % relative humidity.
