Dyno for PPE down pipes

[DJE624]

Great write up Tom!  I'm really excited.  Three more hours and we start on my install!

Quite the story!  Those wheels look awesome spinning on the dyno, and the coated pipes are killer

Thanks.... I love the pipes... and I love the way the wheels disappear at speed.

Great write up and Pics !

Ordering my catless DP'S from 4DR next week !

great write up. i too was amazed by the bends & flat areas of standard down pipes & how ugly they were. my SS ones were really nice looking ones but your coated ones are just unbelievable. those are the kind of things the real top cars have at car shows then they put those standing side mirrors around the car so you can under the car.

Thanks Mike! 
I think the stainless are way awesome also... but with my black ride.... and theme, it is as you point out, one of those little details.

It's also frankly an attitude thing... like having confidence because your underwear is clean without a racing stripe!.

Thanks to Tom for letting us use his car as a test vehicle and again in the future.

Thanks for sharing.  Did you leave the third shared cat on??

Yes, as pictured... saving space for the cutout.Then depending on gains with that I'll have to decide on catbacks vs just tips. 

DJE is installing his DPs today and may have the third cat deleted... Hopefully he'l have a report and pics.

good info all kind of how I expected. Once your're tuneed I'd like to see an overlay of the stock pipes versus catted, and non catted if you're willing to put the stocjers back on for a pull.

How did you get crank hp on a dyno ?

The dyno does a drivetrain loss evaluation by doing 0-60 pulls and coasting down

What % is the drive train loss?

interesting never heard of that, and my guess is that's becasue I don't understand why you would dyno that way ? unless your're trying to do a comparrison at the crank to what Ford reports the stock power output to be ? What is the stock power 365hp ? that would be a 40hp gain for the non catted pipes if the correction is accurate ?!

The dyno treats torque #'s wrong if looking at to the wheel calculations, they're way off - the line is right, number is wrong. I would assume that he is 20HP over published numbers (underrated) compared to quoted 365.
The key is the comparison #'s not the my dyno vs your dyno #'s scenario. I wanted to get the differences between stock, catted and catless. We'll be going back with Tom's car to compare stock, catted and catless tuned as well.
