The guy I worked with had quite a bit of experience with both and said it was consistently 12-14%

Sorry guys, this is a dumb argument considering all dynojets are different. The numbers are what they are. If you want the piece of paper to say something different, go to another dyno and I promise when you get that sheet with a higher number your jeep will not be any faster at the track.

This is true. It is all really about the ability to tune your vehicle with the most likely real world conditions.

I agree Andy, having worked with a local shop owner that does a lot of dyno tuning I've learned that it basically comes down to how the dyno is calibrated. Basically all the dyno is good for is getting tuned and seeing the HP and TQ gains, not to be used for a pissing contest. Time slips are best for that

dyno sheets are just a gear pull,
add launching, hooking, shifting, and making it down the track in one piece and you ll find that a dyno pull dont mean sh!t. Id rather run faster than my dyno numbers say I should than slower.

I get that every dyno is different guys, so is every pass at the track, temp, humidity, baro, da, etc... These threads aren't meant to be scientific, lol.

It's funny that Paulo can run a second or more quicker than most of the other guys with the same power, so we have to come up with excuses somehow.

For what it's worth, the Mustang dyno by me reads 10-15% lower than the surrounding dynojets and dynomites. It's all in how the owner operator has them setup. I couldn't get my turbo to light on the mustang dyno for some reason, but on a dynojet it wasn't a problem.

???whp/???wtq from 5.5psi = 11.72 @ 119.25mph

once i get a driveline in & can up the boost without worrying the tranny will grenade i'll have baseline #'s on 5.5 psi and then up the boost to probably 10'ish

MPH and weight are your power, no hidding it.
