Not elite but as many of you may have seen RCD went 7.60-7.70s with 72/74 and swapped to a 75/77 and went 7.45@92.

big difference from a reg cab to a cc though. bout 1000 lbs.

Size: Good for spool up and power.

JD's truck impresses the hell out of me with this turbo. I'm excited to see what comes of the 59vgt testing coming up

Is the housing bigger on the exhaust side or no?

Thing is definitely heavy. That Road Armor with the Pusher bar and the 35" Nittos weight it down quite a bit!

I dont care if its reg cab or crew cab. All I was referencing was the difference in times with the 72 compared to the 75. Times between the two trucks whether they be reg cab or crew cab with only change being atmo charger from 72-75 or 76mm in this matter should still net the same gain.

So your saying that being JDs truck is a crew cab he wont cut off .15 in ET or close to that with only change in being the chargers? That is what I was getting at. Granted it was a diff day/night. Or a I not thinking correctly here..

I'm confident JD's truck would run slower switching to a 75. That's been proven in testing. If that's even what you're asking

His posts make no sense lately but I think he's trying to say that whether it is a crew cab or reg cab there ETs would drop the same amount by jumping up to the 76. The answer would be no. It takes more power to continue to move a heavier rig. Wind resistance etc is exponentially greater with larger trucks the faster you start to go
