Hey there. Getting ready to do a TSP cam swap on my 2017 5.3 Sierra and I’m wondering if the Msd intake is worth putting on at the same time?
I’m looking for a list of parts needed and if anyone is seeing worth while gains from it?
Currently have a K&N intake, pacesetter longtubes, true dual exhaust with an H pipe, and 4.88 gears. Thanks in advance
Hey Forum - Do any of yall have results from running your L83 on a dyno? I plan on doing a Black Bear tune soon and was going to do before/after dyno results. Curious if anyone has results to post here that I can compare to.
My truck is a 2014 LTZ Z71 with the 5.3L and 3.73 gears (9.5in rear end) from the Max Trailer Tow package. I have a K&N CAI and a custom dual exhaust where the muffler and resonator were deleted.
FYI: I was reading this thread earlier. My truck is currently governed at the stock limit of 100mph. So, I assume it would still be safe to take on the dyno.
If this is posted in the wrong spot, please let me know as I am new. I am looking for some advice from some other guys who have gone down the same path I am about to go down. I have a 2015 Silverado 5.3 and next week I am ordering an on3 76mm ball-bearing turbo kit for it, Snow Performance Stage 2 water meth kit, 4'' exhaust and a converter (not sure the stall, HELP!) My goal is 620-650 rwhp. I have a friend who put down 614 on meth with a 70mm kit and a 3200 stall precision converter. My questions are this because I am not as familiar with this L83. What will factory fuel support? will I need a pump/injectors to get in the low-mid 600s? What would be a good converter to use on the street but also still be able to pull an open trailer with my sidexside (RZR XP Turbo) on it? Who has experience with On3 turbo kits? Vengeance Racing, a very reputable and trustworthy shop here in Georgia will be dyno tuning the truck for me once I am done. Thanks guys!
Hey all! Hope everyone is having a wonderful Monday morning. I’m reaching out to y’all because i purchased my 2014 Silverado 5.3 used, with 76k highway miles. From purchase, it had a decently loud engine, which after reading some posts about direct injection and the oil delivery of these engines, thought it was normal. But after comparing engine sounds to other 2014-2016 5.3 engines, I’ve come to the realization that my engine is obviously not operating the way it should be.
My transmission acts up a bit, but that’s GM transmissions... I’ll have it checked out when I take it for a warranty service.
Anyways, I wanted to hear what you guys think on this topic. I can’t seem to figure out what the whining is from, and why it’s incredibly quieter on other trucks. Maybe my (part that produced the whine) needs to be replaced? I don’t know what it is. My starter grinds sometimes and it’s a nasty sound, but I heard starters aren’t covered under warranty. Then, I noticed, if I get on the pedal and let off, there’s a chirp...I have no freakin clue what that is, so any insight on that helps. Next up is my lifters. I have to definitely get new lifters, and I heard that the lifters go bad after many miles thanks to the B.S. AFM. Once I get the full service I’ll be tuning out the AFM.
Then, finally, is my driveline. I get almost like a “clunk” somewhere along the driveline towards the end when I’m coming to a stop, and going... I think it might be my UJoint.
Thank you guys for any input you leave, it’s greatly appreciated.
Okay so I bought a new Silverado last year, the day I took it home I installed a number of things, one of those things being a wix "coolant" filter Part #33032. GM actually has a perfect quick disconnect on the fan shroud so I just unclipped that and slid the filter into place.
Why? I've just always been curious on a brand new truck. Does it actually matter? I don't think so because the trucks don't have a coolant fed oil cooler that could clog like the corvettes do so I actually might recommend it to those guys who do.
What I found interesting was once I opened the filter there was a ton of gunk of a muddy type consistency. I've included a few pictures keep in mind the truck only had 7500 miles on it or so when I took this filter off. I don't see this playing a huge role in the lifetime of a vehicle (which is why GM probably doesn't include one) but I'm sure the gunk would clog small radiator/engine passages over time (years) of course.
