I really don't think track times will tell you anything. Side by side dyno graphs would. And like said... the turbos were swapped same day and run right behind eachother
Diesel Power mag to test MTW vs. Elite

To go through all the trouble of swapping turbos, dyno time and making an article and just give us a hp figure is unreal. No egt, tq, track time, lag, or psi info is just stupid. I would never buy an mtw turbo but you guys getting all hyped up over 70hp are crazy.
:bowfast::bowfast:
I would love to see the graphs!
Not defending or pushing anything or anyone... I can just learn a lot more from a graph
Ok... although not likely, not plausible, and unrealistic... I made a stupid dyno comparison as to why it is important to see the dyno graph and not just know the numbers.
Which one of these vehicles would you rather drive? One did make about 70 more hp
Now please note I did no calculations on this stupid drawing and am not accusing anyones dynos of looking like this.
I am just pointing out that peak hp only as the sole number you get can be very deceiving :thumbsup:

i would imagine since its for a magazine some of the info will be disclosed untill the mag comes out, i would assume that they will post graphs and other data when that all comes out. I mean afterall its a magazine, they need pictures.
The graphs will tell more of the story for sure, i can't deny that. But 70 peak hp is allot imho.. i mean thats half a second at the track in some casses. And its hard to get any track testing done this time of year, it snowed yesterday and im only 100 miles from where the testing was done (if it was done at elites shop)

For what I see around here it's the same BS on all the boards.
BTW why stick around when the evidence comes out to show others and myself knew the truth all along.
For the testing wasn't the Pmax was out the box as you would buy from Garrett. Didn't the Elite and MTW have billet compressor wheels?? Were the compressor wheels stepped or versions of a single plane design??
Apples to apples how about you swap in a single plane compressor wheel on the "boxed" Pmax and run it again. See how far apart the HP numbers end up for all three turbos.
Thanks to Diesel Power mag for showing at least half the truth.

Given the way the testing was done, None of that info would make up the 70hp loss seen on the dyno between the two trucks. It was as controlled as possible. I think some of you guys are grasping at straws here. Adrian acknowledge where he knows changes need to be made to make the gains he wants, that's all that should really need to be said to solidify the results.
correct, glad to see one person understands LOL

Didn't think of that, I'll buy the mag. Good people in this thread. Valid points were made, I learned something, minimal bickering. Why I love psa. (Slightly off topic lol)

i dont really think that was the point at all....
They are comparing turbos that are available, how many wheel options are available for the pmax? I mean i dont think there are many "wheel only" changes out there. Maybe a WW2 and.... well i cant think of any others.
They are comparing whats available for turbos. The pmax is sort of a baseline, its been around long enough for most people to know what it makes power wise ect, i think its smart to use that for a testing "standard" if you will, Sure we know it makes more power than a stock turbo but how does it hold up to competitors turbos? I mean afterall thats what everyone REALLY wants to know

According to Adrian, DP already said they are not going to include the MTW results since it fell below the stock Powermax results.

He also stated that this turbo is no longer on the market so it's not like anybody can buy one thinking it's an upgrade.
Personally I think this is good for MTW , if they are willing to change the product as needed or as test results come back then they can only improve their product base......and that is never a bad thing

It could be an upgrade for certain people (not given enough info). Sadly enough I bet dp couldnt find a way to convince people the mtw turbo was worth buying. Even with the hp loss if the torque was improved and the egts were dropped I think they would have still mentioned it in the mag. My conclusion- his turbo sucks but he's working on it and willing to admit it.

Besides, the WW2, batmo, and single plane you only have 3 true options. The billet single plane based of the Garrett GTX wheel. Some has said just swapping the wheel out has seen better manners on a stock pmax out of the box but you as well as i know you can only change one side of the turbo so much before ypu have to start to equally match the other side. If not surging becomes an issue as well as back pressure issue. Its a fine Art understanding more power to guys building turbos and figuring things out and matching the correctly and getting the best out of them.
