  1. I don’t think a stock 5.3 is putting down 383whp/414wtq...
  2. What is the blue run, same engine/blower but much lower boost?
  3. Well so much for a tongue-in-cheek titled post looking for ACTUAL data from ACTUAL people who have supercharged their trucks to help provide insight to people ACTUALLY looking to spend $6-10k on improving their truck's performance...back to your normal "what size tire will fit with what size level" posts...
  4. I've got a pretty fair handle on how forced induction works and how various mods increase performance in unison. What I'm asking for is first-hand accounts from people who have BTDT, including if their gains came from, say, E85, long tubes, dyno tune and a smaller than standard pulley vs. stock fuel/pulley/blower tune. My interest is less on all-out top-performance drag vehicles (why you'd do that with an L83, I dunno...) and more daily drivers or at least frequently street-driven vehicles, to include drag pulls or 'truck stuff' like hauling and towing. A consolidated thread of results might help those of us considering spending the money... Nope, it was intentional, for attention. And it seems to have worked...lol
  5. I know there are multiple threads floating around where people have put blowers on their trucks, but wondering if we can consolidate before and after results for those on the fence about going forced induction. I've seen what the manufacturers state (Maggie claims 05/105, Whipple claims 150/150, etc.) but curious about actual trucks in the real world. If you've supercharged your 14-18, I'd be REAL curious to know the year, engine, transmission, chosen blower, additional mods (if any) and before and/or after dyno WHP/WTQ figures. Dyno graphs if you got 'em would be super too! Thanks!
  6. Yes, installed AM-AutoParts AM-3375422714 (identical to 1A-Auto 1771) on my 2017 CCSB this winter, with harnesses and fold switch from Phil Gamboa. Some light reading for you here:
  7. Saw this earlier today and thought it might be of interest...
  8. A good dyno tune (including TCM) totally changes the way 5.3s feel...because GM's torque management sucks ass. But yes, coming from a diesel with peak torque below 2000rpm to a 5.3L is going to leave one's butt dyno wanting...
  9. The TFL truck video showed the 2500HD crew cab standard bed 4x4 diesel LT had a placarded payload north of 3200lb! A new higher GVWR of 11,350 (vs. 10,000lb) puts the 2500HD crew cab 4x4 diesels squarely into 17-19 3500HD SRW territory in terms of tow rating & payload capacity.
  10. This is the slip with truck, full tank of gas, me, WDH, camper with battery and two full propane tanks, normal camping stuff (hoses, etc) in the forward storage and 2/3 full fresh water tank. I would not normally tow with anything in the tanks, so that's 200lb that would be immediately shed shed from the tow slip weight. GVWR is 6,000, GCWR is 12,000, GAWRF is 3200, GAWRR is 3500, truck's placarded payload was 1447lb. I don't camp with 100lb of firewood, a generator, multiple full cans of water/gasoline, or a full Yeti 110. Wife and two young kids are 250lb total; bedding, clothes and food for three nights wouldn't be anywhere close to another 250lb but let's say it was; I'm still 300lb under GCWR which means I've got a little margin to play with. Is it close? Yes, and that's one reason why I upgraded to a Silverado 1500...but it is not over. In my profession, I'm used to going *right to* manufacturer weight limits but never over, because in my industry doing so could cost me my career at best and my life at worst...and will never understand folks on the internet making assumptions that everybody pulling a camper packs the exact same way they do.
  11. No I wasn’t, and I have the scale slips to prove it.
  12. Current-generation Colorados aren't your daddy's old S-10; their capability is FAR closer to 1500s of the late 90s/early 00s. And the reality is precious few folks who own full-size trucks *actually* use them to do "truck stuff". I traded a 2002 Dakota Quad Cab 5.9L 4x4 that I loved for a new 2016 Colorado CCLB, and the Colorado did literally everything better than the Dakota. It was comfortable to drive, easy to park, had more room, got a LOT better fuel economy, had a much larger bed, rode better, etc etc etc. It also was 15-20% less expensive to purchase than a comparable 1500 LT. The Colorado safely pulled a 32.5', 6100lb dry travel trailer within all placarded limits (GVWR, GCWR, RAWRR) when loaded with my family and ready for a weekend camping. The Colorado pulled the camper just fine, but the little 3.6L was turning 3500rpm going 60mph on flat ground and I knew the truck would run out of power on any significant hill, so I traded it in on a 2017 Silverado 1500 CCSB as a better tow vehicle. The Silverado 1500 has more room, gets 2.5-3mpg less than the Colorado doing the same driving, and has more power and is more stable towing the camper. I miss the extra bed length though for hauling stuff, and have been casually looking for at 17+ crew cab standard bed NHT trucks for that reason. If I would have had the baby Duramax, I probably would still own the Colorado as it met all my needs. With the 3.6L engine, I'd have NO issues pulling 5000lb (or 6k that wasn't a wind sail) on a regular basis...and I hope the turbo four-banger finds it way into the Colorado in place of the 3.6L because that engine looks just about perfect for a midsize truck. Wife is glad its gone though...she always thought the Laser Blue looked purple more than it did blue.
  13. I’d guess MANY would pay $221 for a factory-installed foglight option.... Thanks for the info on that! Any insight on SiriusXM?
  14. Earlier this year I installed 1AMRP01771 mirrors on my 2017 Silverado with Phil's harnesses. I am very pleased with the mirrors; the only complaint I have is I get a slight whistle while driving down the road that is not present when the mirrors are folded. I think the whistle is coming from where the forward part of the running light lens meets the front mirror plastic. I cannot hear it with windows up, only with windows down, and it is little more than an annoyance that I think a clear piece of packing tape can fix. For saving more than $500 compared to installing factory DQS mirrors, I can live with a bit of wind noise.
  15. Since GM decided to reorganize equipment packages (and further move away from ala cart options) and decided the 'New Silverado' wasn't worthy of foglights in LT trim, despite them being standard on the All-Star package of earlier trucks...anybody know if one could buy the OE foglamps and do a plug-and-play install? If so, looks like maybe the light switch would need to be replaced? What about adding SiriusXM to a LT truck? I've read somewhere on the interwebs the dealer can update the OE radio for SXM, so it must be true... Figured somebody here would know the answer to both questions...thanks!
