churches dyno is on the hub. their numbers are alway going to be higher numbers than what is going to be if it was towards the wheel.

Yeah..but you can pretty much factor that in. They SAY that their #'s are 10-15 HP less than Dynojet. So...just take that off from Frank's...Bob's (and mine too) to get an *equivalent* Dynojet. Still great #s.

you have to take the averages of all the different dynoes, so it would actually be about 10, as dynopak ranks in the middle, and all dyno's run different #'s, i bet you compare 3 dynojets, at 3 different locations, you would get 3 different #'s, all i know 272 stands, and know one here has topped it except me....................

well here is a comparison of different dyno's, Turbo Magazine Dyno Dash Comparison Chart

Dynapack 249.4 242.8
DTS 257.6 XXXX
Dynojet (Win) 235.8 227.8
Dynojet (DOS) 243.7 237.2
Clayton 265.7 240.6

It's hard to compare nowadays.. Even the Dynojet themselves have varying age and software and they show 10% difference between each other.

It's more of a lucky thing, so if you find a dyno that reads consistent, and you like the shop you are dealing with, then stick with that dyno. It is only a true before & after dyno run that will put your numbers into perpective.

My particular Dynapack wasn't really "calibrated"... One of the local Dynojets around my area just happen to spit out numbers that were higher than my Dynapack. If any calibration was done, the "TCF" correction factor will not be 1.00 anymore. Mine is still 1.00, means no correction factors was added or subtracted.

Funny at the same time, another Dynojet in the east end area reads lower than my Dynapack. So now I got two Dynojets that read higher AND lower, so who knows, I don't even know what to tell people anymore.

The best way to verify a dyno (if it is a very important subject matter), is to send a bone stock Solara, or any bone stock car around the same TQ and HP level to that particular dyno to grasp a useful baseline figure.

On Shawn Church's dyno, his read higher... Even he himself knows it so he tells you it's between flywheel HP and Dyno WHP.
At the same time though, Shawn's dyno area is very clean, well ventilated and is at a good location. It's hard to pinpoint whether the dyno itself is reading higher, or the ideal shop conditions are making the numbers higher.

On the dyno, especially during a long night of tuning, the numbers are always going to be lower because the car is hotter, the air inside the dyno area is now polluted and full of exhaust, and the air during night time has less O2 (yet elevation is unchanged). The same car dyno'd at the same place, during 6:00am in the morning and a dyno area full of fresh air, will give higher numbers...lol So really, your numbers during a private baseline session will be higher, but your numbers during a group dyno day (with your car being one of last cars to dyno), will read lower.

Trade secret!

after the upgrades , this will be the 4th time at churches . the 1st time was after the sc was put on. 196 hp. the 2nd time, after some more mods, bigger pully and some other goodies , 248 hp. the last time with the headers and 3" exhaust everything came together for the 272.4 hp. this next time , more goodies . i think mid 280's is close .
