and a bunch of LX'ers oh I mean all of the LX'ers.Dyno's are for tuning.
Best way to compare power is to go to the same track on the same day, like we did at ATCO this weekend.
For example, this showed that Big AL G and Jack SickSRT's Challys were both faster and quicker than SRT5939's challenger
That Car is making some Steam!!I know everyone has seen this video but look close at the screen. SAE results are 420 hp. Uncorrected numbers are 440 hp and uncorrected can vary alot more than 20hp.

Makes a lot of sense. Like when I am working up a load for a rifle. I will play with the powder and bullet to find a combo that it likes. I shot it though a crony and then try it on some paper. If it does not like the set up I try some thing else. I am shooting for a combination of accuracy and speed of the bullet. This gives me maxinum killing power. I use a crony as a tool to help me tune my cartrige as we use dynos to tune are rides. I am just not looking for killing power in my car, just speed as fast as a bullet.Here is part of the deal, most dyno have a "weather station" module to allow the system to correct to sea level which is what SAE Corrected is when it is selected. The problem comes from where they keep it, if the keep it clean and in free air or in a warn cabinet on a cold day etc.
This information is saved in the dyno files, so you can set the corrections.
Something else you have to watch on a dyno is heat soak or an overly cold run will skew a set and give false numbers.
Think of it this way. At sea level I run 12.7's at -1500 Da i run 12.0's I make 50-60 more Hp in good air.
The differences at tracks are things like rotating mass, sprung mass, weight, traction, rolling resistance and mechanical loss are all going to effect runs also how you stage the car. Cold oil will rob you silly. heat soak will do the same.
Guys that have a plan, and stick to it tend to be very consistent because they don't break the routine and have found what works for their combos.
It took 150 passes to get mine sorted out. Playing will coolant temps, oil temps, trans temps and leave RPM's, staging, and shift points.
The biggest mistake I see people consistently do it to buy stuff install it and spend no time logging, dealing with the tuners and getting the combo right. If it isn't laying down what someone else is running with the same combo they think they have crap parts when its a matter of a tune, or running the car right.
Dynos suck they are a tool if used right for seeing changes and getting run data when you can't get to a track.
Great idea. Hope it happens. It might be interestingIts one of the problems with dyno's.............they are not consistent from one dyno to another (even same manufacturer type dyno's)
That's why is so important to do your tuning and baselines on the same dyno.
I think it would be awesome to get a mobile dyno out at challengerfest 2011 for cars to get on and do pulls and see what we are all putting down across the forum on the same drums
