Hillside Cycle 124"

Both SAE and STD are corrected numbers. THey are corrected for different atmospheric conditions. SAE is standard in the US as it corrects to the average atmospheric condition in Detroit Mich. (when they came up with SAE Detroit was the main hub of the auto industry so that's why they picked it). STD corrects to another region of the world (i'm not really sure where). There is the option to use UNCORRECTED which is actual numbers produced in the conditions the bike was ran in. STD conditions favor SAE conditions by about a 4-6% average (depending on the actual condtions the bike was ran in)

Seems to me that most tuners provide sheets in SAE, So when I see a std sheet I find it odd. In this case this 124 Is a runner either way. At that power level it doesn't even matter. The shape of the curve would probably remain the same I'm guessing. Impressive either way. I'm doing a 124 with 640s now. Its the s&s hot set up straight up in kit form, and a se58 tb. Won't be anywhere near this threads numbers or curve shape.

Bingo!...........lol!

I agree with this as well. Potential customers of theirs posted here asking to see it in SAE, you'd think it would be easier to just post the sheet then play these cat and mouse games.

Most people do not have a clue how to really read a dyno sheet. The Internet has turned it into a game of how to trick the dyno for bigger numbers. If 3/4 of the riders would be honest they only run the engine from idle to 3500 RPM 95% of the time they ride the bike. So pick you poison when you read them anymore these days. Where the torque curve is and how it is shaped tells you so much more than what the peak numbers tell you anyways. For a daily driver big numbers typically suck when it comes to real world performance, as you are out of the performance area most of the time. This sheet shows 120 Ft Lbs about 2500 which is good and if you drop it to SAE that would most likely be about 115 Ft Lbs which is still good. The shape of the curve is nice but I would like to see the runs start a little further down the RPM scale (1500) as that is what you use each and everyday you ride it. The dyno doesn't give a rats *** where you start it, but typically they do not look as good, as when you start it at the higher RPMS.

Looks actually like 124tq at 2500rpm so 120 SAE lets say.
And I hate to disagree here but the only time anyone should see 1500rpm is for 1/2 second off idle, or if one rides parking lots all day. 2200/2300 rpm is a good place to start a big motor pull IMO.

Wasn't posting to toot our horn about peak numbers, but rather the shape of the curve, off the bottom/lower mid range.
You don't see that from an S&S .640.
Borezilla with a Q baffle.
11.4 cr, and our proprietary port work we perform to S&S Super Stock castings at that level.
Another one leaving this week in a 2005 Road King.

Your lack of posting it, tells me all that I need to know about you.
I'll stick with the S&S crate.
