Correction Factors the same as bench racing?

I agree, you had to stick your head in and stir up the pot.
ER didn't have this directed at you or anyone other dyno owners out there, he was just discussing correction factors and the facts of some dyno's. What happened in between was all your doing.
Someone took things a little too personal or to heart.

Copied and pasted from what I wrote on AMS thread about dyno's."I recently opened a shop in the pittsburgh area, where I purchased a mustang awd 500se dyno. I constantly hear people complaing when they come into the shop saying oh well im happy with the tune, and the numbers but I think the numbers will be higher on a dynojet. Which is true, most people just need to realize that mustang dyno's do read lower than most dyno's on the market. I actually had to personally test and prove to people that my dyno was calibrated correctly, and had the tech guys from mustang dynamometer come out to my shop,to check over the dyno and make sure everything was correct. I then used my own car, along with two friends cars to test the calibration on the dyno. My Honda Del Sol, put down 596whp on a dyno jet, on my dyno, i made 573whp. Which to me with the variation of temperatures, and length of time since the car was tuned, was very acceptable. I then tested a friends buschur built evo, he made 577awhp on buschurs dyno. On mine he made 574awhp, then tested another stock turbo buschur tune, he made 325awhp on buschurs dyno (btw we have the same exact dyno), on mine he made 324awhp. I actually had to have conversations with people during dyno day events, explaining things. In the end the only people to blame for shops "inflating" their numbers , are the customers. Customers want high hp numbers, most people dont simply realize it's the curve of the graph, and the torque behind that hp, that makes a car fast. I actually recently had a new 2010 camaro ss, that came to us for a tune. Supercharged, full exhaust, meth injection. He made 588rwhp and i belive 590ftlbs. The car drove like a bat out of hell, then on the local forum he posted his results from the tune, after he put the car on a dynojet, because he wanted the numbers. In the end everyone has there own preference on there build, i think everyone saying that the dyno they start there build on should be the one they finish it on. Dyno's are incredible tools for tuning cars, but in my opinion dyno numbers are simple bragging rights and that's it. Depending on the build, the way your car preforms against the competiition is the true bragging rights. I had one guy come through the shop that really impressed me. Trying out the new htagreen on his evo IX. He said " numbers dont mean **** to me, ya I'd like to see around 450-500, but in the end my 1/4 mile time and trap speed are the only numbers I care about".
Obviously every shop is going to be praising there dyno more than the other. Dynojets are good dyno's to tune on, however it is all inertia, there is no force behind a dynojet, so yes when I hear people come to me and say my numbers will be higher on a dynojet right? Yes they will. Take a 350whp(dynojet) stock turbo evo, and a 350whp(mustang dyno) evo, and race them side by side. (putting into account same modifications, and equal drivers.) Which one will come out on top? As i stated before, all the hype about high hp numbers is what ruined dyno's, and started this whole debate. In the end the way your car preforms is the true test dyno numbers are just a way to measure your dick.

The problem i find using un corrected is when comparing cars dynod on different days the #'s will be way off.. Atleast if it was hot today and cold next week the 1.02 vs .99 correction will allow us to better evaluate the changes made.. for us the correction doesnt move anything more 3% really 1 way or another but gives a us a better idea of where we lost or gained the HP in the midrange when it was on 10-15hp lost or gained there..

Again, all these other "competitors" with other dynos aren't crying like you are. You just make yourself sound guilty when the blue and red rains down.

At the end of the day 1 Fact Remains.. DYNOJET is the industry standard and there are more of them used then all other manufacturers combined in the US.. They are not able to be manipulated by any great deal and the correction factor shows clear on the dyno sheet..

Theres more of them used because they were cheaper, most shops only bought 2wd dyno's, now people are adding on the extra rollers to make them awd, because the scene has sky rocketed since the evolution production. As I stated before there is nothing wrong with dynojets, I have no bias against them. However proven fact is that a load based dyno system will read lower than an inertia system. If shops out there want to inflate there numbers, so be it that's there reputation to worry about. Times are changin though , and more and more people are realizing the benefit of a load based dyno system. I went with mustang because I have tuned on both and I find a mustang dyno easier and better to tune with than dynojets, that is my personal opinion though. The industry standard is not dynojet, the industry standard is proving that your tune, or shop, or product will out preform another shop, hence inflating the numbers.
In the end everyone here is simply trying to protect there $100k investment, and keep people coming through the door, the real people that have the choice to decide is the customers. And like many of you have in your signatures, it's not simply the dyno numbers your bragging about , its all of the stock turbo evo's going 10's, and your companies built block going 9's, your shop car going 8's, at the end of the day its, how the car preforms that puts a smile on the customers face, not just dyno numbers.

If a guy walks in unknowingly with a corvette and wants a dyno pull to show his buddies that his 400+hp crank corvette can put down XXX HP i dont want to have to explain " well sir dont be disappointed, your car was not built on a friday and its not broken, its just that we use a dyno dynamics that reads very low ".. i also dont want to add 1.2 correction to make him happy.. I can sleep at night knowing our dyno puts out what is considered an INDUSTRY STANDARD HP figure..
I was just elaborating more and not arguing so you understand.. Im comfortable with what our dyno reads and what our cars run.. under 800hp in the 8's with our RS, and 920whp to get into the 8.7's & 167mph.. Our dyno definitely is not inflated and i am happy with.. Our tuner Crispeed prefers the dynojet over all others 95%.. drivability tuning of course he prefers a load bearing dyno but still gets it done perfect on our dyno just more time consuming for him..

You said it perfectly, you dont want to have to expain to him that his 400crank hp corvette doesnt make mind blistering numbers. I for one dont care if his car puts down 200whp, my main goal is to get him where he wants to be. But in the end , its not our job to adjust that correction factor, so theres a smile on that customers face, it's to have them spend money at out our place of business, that will throw them back in the seat and then put a smile on there face. Customers simply just dont realize that what the car is being stated as, is not truly what's being put down to the pavement. Hence a load based dyno, why I like it (other than tuning) you need strive farther to reach that hp goal, than on a simple inertia design. Load on a dyno, is simulating load on a street. No its not going to be 100% true, however the day when customers except lower, more accurate numbers, IMO, is the day the world will stop spinning. Performance shops weren't built around dyno numbers, dyno's were built around the performance of cars, so to base how fast a car is off of a number a machine spits out, is wrong. However its what has come, and what is accepted.
