[QUOTE="euroford, post: 1524752, member: 17667"] Well, that was a successful holiday road trip. I guess it’s safe to assume that new turbocharger is broken in now. In total, we did 843 from Louisville CO to Davenport IA, then another 440 on to Midland MI and returned from Midland to Davenport with a stop off in Chicago to have dinner and a beer with friends for 469 miles and then on back home for a grand total of 3,064 miles of driving. To diverge into thread drift briefly, I’m surprised everybody gets so wrapped around the axle on air filters. Though no doubt Donaldson filters are fantastic, maybe the best, I’ve certainly never felt that my washable type filter is holding me back or causing any damage. Around these parts, everybody loves those, but otherwise I’m inclined to think you’re good to go assuming you keep up with maintenance or replacement as required. My 1200hp mustang ran K&N style filters, so did my 650hp sierra cosworth, as does our current BMW 540i, my CJ3a crawler and my wife’s aftermarket turbocharged Ford Escape (2.5l Duratec with a BW EFR 6258). My Hideous filter was freshly washed before that photo, and looking/running basically brand new and ready for our road trip. Now that we’ve racked up 3k miles, I’m due for an oil/filter change, clean the air filter again and replace the Baldwin fuel filters (I replace them every other oil change, likely more often than necessary). But… I do think I’ll seriously look into switching to a Donaldson filter, more for convenience than anything else. Washing filters is a pain in the arse, and I’d frankly rather spend my time doing something else. But for the time being, to do that I’d need to figure out what filter will fit my large AFE intake tube. I do also REALLY like that dual filter setup that MeTo shared, it would be a fun little project to build something like that up with some aluminum tube, but I’m afraid that I may not have room in the airbox as it shares space with the battery. The filter socks are a very good idea. AFE makes one for my filter ($30), I don’t use it all of the time, but do throw it on when we head out to the desert. After a long weekend in Moab the filter sock will be totally red crusted, then I can pull it off for the drive back home, where you need all the air you can get eastbound over Vail pass. Anyways… back to new turbocharges and road trips. In addition to the new charger, we also picked up an Escort Max II Platinum radar detector on sale at Costco. This turned out to be a fantastic decision, as we made some excellent time through the desolate wastelands of eastern Colorado, Nebraska and Iowa. I’ll spare any further rambling to just say that the new Escort worked excellent, and was a great deal through Costco, and we give it a solid two thumbs up. As for the turbocharger, it has revolutionized my truck. Though it’s easy to focus on making peak power, huge dyno numbers or hauling massive loads, this trip was none of those things. This was all lightly loaded, high speed interstate cruising. But this new charger just made it feel so smooth and effortless that it made the drive so much more pleasurable. Booking down I80 at 95mph it would make a steady 10ish PSI, and show about 14psi of backpressure. With the cruise control on it would smoothly snap as high as 24psi to maintain speed up hills, and again backpressure would stay within about 4psi of boost. If I had to slow down for traffic (or more often, a schmuck sitting in the left lane for no good reason), I’d then click back in the cruise control and it would surge as high as 35psi to bring us back to our cruise speed. I left it in the “Hot Street” tune for the entire drive, and for the most part with wife/family/dogs in the truck, I keep my driving smooth and steady. My 8 month old male Shetland Sheepdog likes to chill on the center console, so I didn’t really want to send him rocketing into the back seat, though I can assure you that would be easy to do. Driving smoothly with the new charger is a vastly easier task than it was with the stockish setup. By comparison, it always felt like you had to really work the stockish charger over to get it to respond. The stockish charge could make some power, but it just felt like I had to pretty aggressive with it. Shift hard, floor it, wind the rpm’s out, all the time. It was like I either had to be slowwwww or ON IT. The new KC38r on the other hand, is very responsive to part throttle driving and comes on very smoothly. Using about a ¼ throttle in traffic or heading up an onramp it’ll very smoothly build 10-12 psi in 1st, 2nd and 3rd without jerking my occupants around. Then if I’m merging I can tip into it in 4th, build over 30psi and have more than enough speed to overtake merging traffic and get on up to my cruise speed. Interestingly enough, with mellow driving I noticed very little difference in behavior due to altitude. I’m at close to 6k here at home, and were at near sea level obviously for the rest of our trip. I have no doubt that I could have found a difference if I was making some pulls in kill mode, but at least for standard driving, its performing very very well at moderate altitude. It’s an interesting contrast that even for interstate driving, the stockish charger was noticeably happier at lower altitude. I had a decently direct comparison as I had just driven the stockish charger to TX and back for Thanksgiving. I’m sure ya’ll would like to know about fuel millage. Sorry to say, I’ll admit that it’s just not my primary concern, and I don’t pay attention to it or log it that carefully. I just fill up when I need to and drive on up the road. If fuel millage was a major concern for us, than the Ford Escape would have been our weapon of choice, instead we choose the interior space and all weather awesomeness of the truck. Despite no accurate logging, I can certainly discern that fuel millage was “better” than before. I can typically expect to get about 450 miles out of a tank before the low fuel light comes on. On this drive, I never ran it out that far between fuel ups, but despite driving a fair bit faster than I have in the past, I think I would have been pretty comfortable squeezing 500 miles out. So, let’s take this with a pretty huge grain of salt, but I think I could jump on a fairly flat highway, set the cruise at 90-95, click off 500 miles and I’d guess that would be about 35-36 gallons of fuel or about 13.89-14.29 mpg. That’s pretty acceptable in my book. I just don’t have the patience to do it, but it would be interesting to drop down to the Eco/Tow tune and actually drive in a manner acceptable to state troopers, I bet you’d get some awesome fuel millage. If you’re into that kind of thing. So yeah, that’s where we are right now. Initial impressions are very good, and it’s also a very satisfying turbo upgrade for road trip cruising. Sometime next week my new solenoid will come in to fix my BOV, I’m really interested to see how this effects transient response through shifts. Also, we typically consider the start of ski season to be after the Christmas holiday, so if we get some snow we’ll go try out some lightly loaded mountain driving. Likely up to Copper. Also, if I can get my rockcrawler (new tires, electric fans and ditched the lunch box lockers for spools) back together, and we get some snow we’ll head out for some snow wheeling and I’ll see how she pulls the trailer up Boulder canyon.
