Message: [QUOTE="akcooper9, post: 1531549, member: 28898"] Here are two others who have made the switch: [url]https://www.ford-trucks.com/forums/1573938-talk-me-out-of-a-kc38r-3.html#post18510725[/url] [url]https://www.ford-trucks.com/forums/1573938-talk-me-out-of-a-kc38r-2.html#post18510125[/url] Sadly I think the hole beta tester thing is a downfall. You have guys buying discounted turbos and testing. Testing what? They have no clue. Heck I was one of them. Had it not been for @TheBrad I would have though it was a great turbo and moved on. I suspect most guys having 'success' are doing 1 of 2 things... (1) Fixing currently exhaust leaks when they install bellowed up pipes and the new turbo (2) Continue to run that heavy tow tune. Not sure what has changed except the switch from ball bearings to 360 bearings. I do find this video on KC's facebook interested: [url]https://www.facebook.com/KCTurbos/videos/107426506862476/[/url] I noticed multiple things that dont add up [LIST=1] [*] EGTs are 1100 degrees...what tune and how much fuel. Based on my experience I suspect its a HEAVY tow tune with close to stock level fuel to keep EGTs low. But like the question [URL="https://www.youtube.com/watch?v=O6rHeD5x2tI"]how many licks does it take to get to the center of a tootsie roll, the world may never know[/URL]. [*] Why are KC's results so much different then BackWood's van turbo with the cloned drop in turbine? [*] 12K pounds...Please the truck weights what 8K and the trailer another 2k. A better test would be a highly wind resistant high profile trailer like a RV or toy hauler etc. I noticed a difference in EGTs when I tow the excavator vs the 5th wheel. [*] How come they don't try recording accelerating from say 1800 rpms to 2300 rpms? [*] OD....really with those big tires your turning 2200-2300 RPMs are 55-60 MPH in OD. You can't tell me KC doesnt know the difference between 3rd and 4th. Either that or the truck has been re geared. [/LIST] Speaking of OD, here is a video towing the 5th wheel in 4th gear on the interstate up an incline (not a 6% grade) making 12-14 pounds at 1100 degree at 1900 rpms. [url]https://www.youtube.com/watch?v=bAIOWKf9EEs[/url] Here is another video in 4th at 65MPH and 1750 RPMS going from 5 to 10 pounds of boost and EGTs stay at 1100 up an incline. Again, towing!
