This section will be for dyno results, your list of mods (before and after) and pics of the dyno sheets and their results.

Any off-topic comments will be deleted. Keep it on track.

Questions not related to the dyno testing should be sent via PMs and kept off the board.

Lets see those dyno sheets.

Big6x6's idea to do this is a good one, IMHO.:thumbsup

Dyno

My bike (2001 FXDXT) [95"Edelbrock Heads, Mikuni carb, Thunderheader exhaust, twin tech ignition] is at Hillsidecycle right now. This is the Dyno run before Scott builds it to a 98ci. I will post another Dyno run pic. when I get it back.

Crane cam. Don't know the specs. I know that it's being swapped with an Andrews cam. Once again don't know the specs. I will let Scott work his magic. I will post complete details of build after I get it back.

Dyno run after build up

95" Edelbrock heads bored to 98" New cam plate.Bob Wood TW-9B cam set with Andrews chain gear & hardware. S/E valve springs. H-D lifter set. Printer was down so I took pic. I'm going to have it tuned again after I get a few hundred more miles on it.:bigguns

For comparison though we did also just do a jims 131 that had reverse numbers from the 120r, still ran good, but for an aditional 11 cu in. Meh, oh and 4k extra for the motor.

Tale of three dyno tunes...

First dyno tuned bike I ever had, 2010 Street Glide:


Max HP- 102.1 @ 5400rpm Max Torque 113 lbs @ 3100rpm


After riding with THAT tune...the Stage I Softail Deluxe felt like a 750. So that lead to THIS tune:


Max HP- 87.4 @ 6000rpm Max Torque 93.2 ft lbs @ 4000rpm
Stage IV H-D kit


That wasn't what I wanted so to Foster's H-D to do their stuff:



Max HP- 102 @ 6000rpm Max Torque 108.6 @ 3800rpm

HUGE improvement all the way around. HUGE difference in torque below 2500 rpm.

The second Deluxe tune featured of course a new dyno tune and swapped the SE 260 cam that comes with the Stage IV kit for a Venom Black Widow 44-TC cam.. BIG difference. Looks to be a LEAST a 13 ftlb torque improvement across the board and 12 hp improvement across the RPM range. About 90 ft lb from 2500-5800 rpm and 100 ft lb from about 3000 to 5200 rpm. I have not ridden it that much YET(raining about every afternoon), but I'm sure it will take the heavier SG now from seat of the pants feel.

Hard not to notice how good of a tune the SG has. The Deluxe doesn't catch up to the SG until about 3500rpm or later. But catch up it does.

Heath said the Pro Pipe is really helping the SG along with the fact it's not a "B" engine.

Pretty interesting!

Got my first tune yesterday...

2011 FatBoy Lo
SE Intake
PC-V
V&H Staggered Short Shots

they said I gained about 24hp over stock
my numbers are:
88 hp 84 ft/lb

sounds to me like 24hp is a lot for just i/e/c.... but I'm glad I had it done it runs smoother...

Correction Method, SAE vs STD

The horsepower and torque available from a normally aspirated internal combustion engine are dependent upon the density of the air... higher density means more oxygen molecules and more power... lower density means less oxygen and less power.

The relative horsepower, and the dyno correction factor, allow mathematical calculation of the affects of air density on the wide-open-throttle horsepower and torque. The dyno correction factor is simply the mathematical reciprocal of the relative horsepower value.

Originally, all of the major US auto manufacturers were in or around Detroit Michigan, and the dyno reading taken in Detroit were considered to be the standard. However, as the auto industry spread both across the country and around the globe, the auto manufacturers needed a way to correlate the horsepower/torque data taken at those "non-standard" locations with the data taken at the "standard" location. Therefore, the SAE created J1349 in order to convert (or "correct") the dyno data taken, for example, in California or in Tokyo to be comparable to data taken at standard conditions in Detroit.



SAE:
"SAE (Society of Automotive Engineers), USA. Power is corrected to reference conditions of 29.23 InHg (99 kPa) of dry air and 77 F (25°C). This SAE standard requires a correction for friction torque.

STD:
STD is Another power correction standard determined by the SAE. Power is corrected to reference conditions of 29.92 InHg (103.3 kPa) of dry air and 60 F (15.5°C). Because the reference conditions include higher pressure and cooler air than the SAE standard, these corrected power numbers will always be about 4 % higher than the SAE power numbers. Friction torque is handled in the same way as in the SAE standard."

Here is some quick math (using assumptions and round numbers):

STD:
Air Temperature: 60F
Absolute Pressure: 29.92 inches Hg
Relative Humidity: 0%

Relative Horsepower : 104.8%
Air Density: 1.223kg/m3
Relative Air Density: 99.8%
Density Altitude: 67feet
Virtual Temperature: 60F
Vapor Pressure: 0 inches Hg
Dyno Correction Factor: .955

SAE:
Air Temperature: 77F
Absolute Pressure: 29.23 inches Hg
Relative Humidity: 0%

Relative Horsepower : 100%
Air Density: 1.157kg/m3
Relative Air Density: 94.4%
Density Altitude: 1952feet
Virtual Temperature: 77F
Vapor Pressure: 0 inches Hg
Dyno Correction Factor: 1

98 Evo
SE-11 Cam, SE Slip ons baffels cut down to only the plugs, SE 10:1 .005 pistons, 44mm CV and intake with SE breather kit, SE Coil, wires, plugs, sel mild port/clean up of heads, dynatek programmable ignition with 6k red line and my own custom curve

just a touch over 80tq with 85hp, however i only paid to have her put on the dyno, not tuned, she was alittle rich in the mid range thus causing the dip in power, i since changed the jetting and gave more advance in that rpm range to bring up the power, never got her re-dyno'd though
