J-Madd Posted October 12, 2013 Report Share Posted October 12, 2013 Not saying you do, but can't anyone just enter the wrong barometric pressure or air density and get a false corrected reading? Quote Link to comment Share on other sites More sharing options...
WINDYCITYJOHN400 Posted October 12, 2013 Report Share Posted October 12, 2013 Not saying you do, but can't anyone just enter the wrong barometric pressure or air density and get a false corrected reading? You don't enter that info on a dynojet. It reads it on it's own, takes into account air temp effects and depending on your chosen correction factor, adjusts the numbers. (Don't get all worked up about the word "adjust" we're talking small amounts) All the settings are clearly shown on every dyno printout, so it's easy to see just what settings were in place for each run. (Not like an operator can tweek a run without it showing up in the settings.) Cameron has even said he can pull a bike off his dynojet ATV dyno and strap it on his dynojet CAR dyno and get the same numbers. So....NO. When it comes to dynojet.....you can't tweek anything like the public rumor likes to say. 1 Quote Link to comment Share on other sites More sharing options...
n2otoofast4u Posted October 12, 2013 Report Share Posted October 12, 2013 But what about all the "this dyno is known to read low" guys? Quote Link to comment Share on other sites More sharing options...

WINDYCITYJOHN400 Posted October 12, 2013 Report Share Posted October 12, 2013 That's just what everyone says when they find out the motor they were convinced made 90-100 was only pushing 70-75. We just had a guy buy an unported 421cub dune/drag bike from a guy in Michigan. The guy had rode it for years and it ran great. The new owner brought it in to check it out on the dyno..... First pass (as bought condition and tune) 80 HP Last pass (after going 4 mains leaner, moving timing and needle and going richer on the pilot) 95HP. (Survived a weekend of hard dune action with his new tune with zero problems) The motor had originally been dyno tuned......so I guess when that guy heard 80HP, that's when a dyno owner says "well this dyno always reads low". In reality that guy didn't know how to tune. Our dyno doesn't read high or low. It reads correctly. Same exact dyno as Lane from Vito's, Mat Shearer's and Cameron's at Redline.......

srp Posted October 12, 2013 Author Report Share Posted October 12, 2013 The correction factor can be changed anytime after a dyno pull, you can chose from uncorrected, std, sae and one other on a Dynojet. You can print and compare runs with different correction factors at will. Heating the stack will raise the horsepower output and a simple turn of a potentiometer on the weather station will raise power output just as J-Madd said. There are lots of other ways to manipulate the output of a Dynojet that I did not mention. 1 Quote Link to comment Share on other sites More sharing options...
Redline Racing Posted October 12, 2013 Report Share Posted October 12, 2013 I keep my stack in a refrigerated room. My dyno or dyno's are stingy. Quote Link to comment Share on other sites More sharing options...

Heating the stack will raise the horsepower output and a simple turn of a potentiometer on the weather station will raise power output just as J-Madd said. There are lots of other ways to manipulate the output of a Dynojet that I did not mention. Well AS I SAID whatever changes you make show up on the screen as well as the printout. So some one would have to be a complete dipshit to not notice that one sheet shows SAE and the next shows STD. You can also use dynojet software to revisit your runs to examine them under different corrections. So one pass can be judged by any or ALL the different correction factors. Also....I suppose you would have us believe that a person can show up and make a pass on a dyno......then NOT NOTICE THE OPERATOR HOLDING A BLOWDRYER AIMED AT THE STACK? The point of my comments are that "If you have eyes and 1/2 a brain" it would be ridiculous to think you can mess with the dyno and get it to show a false reading without people noticing. (I think anyone would notice you going into the settings section of the dyno and making changes at that level between runs.) But on another note: Glad you chimed in Gary. As someone who doesn't own a dyno.......you are certainly an expert on how to "Manipulate a dyno" (Wonder why that is........ ) But like many....your entire argument stems from top brag numbers. (Your only focused on how someone can show a higher number than a different dyno to fudge a final number for brag purposes.) If you follow MY point of view, it all comes from the point of view of simply comparing run #1 vs. run #2 vs your final run after all your tuning changes. Basically any mod that provides a false reading would effect all your runs. So you would still have the same HP gains from run 1 to the last. That's why it's a tuning tool. YOU use a dyno as a number generator for sales!....tell us for YEARS how your In-Frames can make more power than any other pipe on the market (In-frme or Out) I'm sure that is the REAL reason you want to be there for all the dyno testing. You're sure that others will sabotage your pipe's results............... Quote Link to comment Share on other sites More sharing options...
#1JUANstunna Posted October 13, 2013 Report Share Posted October 13, 2013 There ya go. We need all the experts in one room at the same time. Juan could set us all straight in person too. I'll show you bastards how to tune something, and I'll fix your lawnmower while I'm there. Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted October 13, 2013 Report Share Posted October 13, 2013 As stated, Cam and I are not biased in this at all. Neither one of us has a stake in what pipe makes what power. We're both just curious. That's all. Everything will be legit on our end. In the end, I hope to put to rest a lot of speculation about all pipes mentioned and I look forward to seeing how they stack up against one another.

dozer Posted October 13, 2013 Report Share Posted October 13, 2013 (edited) Cams dyno reads within 1 to 2 hp of sandtrax in tulsa oklahoma, sprinklerman and maybe someone else ,if they wana speak up, can post some proof. I am not a redline customer, yet. Edited October 13, 2013 by dozer Quote Link to comment Share on other sites More sharing options...
Colby Posted October 13, 2013 Report Share Posted October 13, 2013 But what about all the "this dyno is known to read low" guys? at LEAST 75% of the time, the people saying that the dyno reads low or high are people coming from COMPLETELY different altitudes...some people havent figured out yet that dynoing at 500ft above sea level is going to give more power than dynoing at 5000ft ...

RagunCajun Posted October 13, 2013 Report Share Posted October 13, 2013 The curves are most important to me. Not so much the numbers. Seeing them over lapped can help me chose the one id like if I were doing a build like that. Quote Link to comment Share on other sites More sharing options...
