i have the 2016 silverado 5.3L 4x4 double cab Im looking to either do a twin turbo setup or a supercharger but this is my only car i drive it every day so i need it to be drivable as a daily driver so I'm looking to get as much power as i can but it also be reliable as a daily driver. my question is with these 5.3L motors do they do better with superchargers or turbo chargers personally id rather do a twin turbo setup but if these motors run better on a supercharger then ill do that either one will have a intercooler and if i do supercharger witch type twin screw/roots/centrifugal any info on what will make a better daily driver/witch do these engines like better id really appreciate thanks in advance

Whether it's turbos, or one of the supercharger types, each has its pros, cons, and characteristics

yea the i understand i know the difference between them all pros cons etc.... what I'm trying to find out is with these 5.3L engines do they like turbos better then supercharges or pro chargers for example do people find that a supercharger creates more problems with overall reliability and with turbos they seem to be problem free just an example trying to find out if these engines like one over the other or run better with one at the end of the day 3/4 into it they are doing the same thing forcing in more air. i prefer a twin turbo setup but if people are finding with these engines its a lot of mantnaince/problems and with super charges/procharges they are almost headache free then i would go with that setup

I've been looking into forced induction as well for awhile, and my biggest concern is if the drivetrain will last me 200,000 miles in its stock form. I'll never drag race it, and I don't care for burnouts. It's hard to get a qualified answer on this. Most answers come from people with little to no experience with them who just say what they've heard. I'm leaning supercharger based on the fact that the only twin turbo system I know of is 10k vs 6k for a supercharger.

A turbo systwm is probably a little easier on the drivetrain as the boost is not instant. Turbo systems are more complicated and create their own issues with reliability.

 

They way to be fully reliable is to mimmick how the manufacturer does it. These means upgraded pistons and lots of cooling upgrades. Most of this is probably not required if you are not too hard on the go peddle.

 

The reliability will be heavily dependant on how you drive it. What kills motors is heat, what creates heat is length of time in boost. I've had a couple aftermarket turbo's with tons of gauges, its amazing how fast iat,, oil temp, water temp, and transmission temp climbs after 10-15 seconds of boost. These rapid changes in temperature are what causes damage. Not a big deal if you have adequate cooling, forged pistons, and gap your rings correctly, but doing it right is no easy task, just ask any manufacturer.

 

I think the most reliable setup overall might be a simple tvs1900 system on low boost. Plenty of people have logged well past 100k miles on these, but it is rare to not replace a transmission during that time. A turbo system can be reliable, but you really have to do a great job on the install.

 

Just keep in mind, in the forum world 6psi is nothing, in the real world 6psi vs NA is night and day. Also keep in mind by the time you're at 100k miles, the drivetrain parts should be pretty cheap. It may actually be better to spend less time and money on the system and just replace the trans or motor at 100k. After all, blowing a motor or trans is an excellant opportunity to install a built one.

I bought a 92 Chevy 5 years ago that has a whipple on it. I'm the third owner, the guy I bought it from was friends with the original owner. It has 110K miles on it and looks good. The 373 rear is original, the transmission just got rebuilt to a stage two rebuild. The engine was redone to a 383 with dart heads MSD and can run 5-10lbs of boost at 80K miles by the second owner. I've done nothing but drive it and do general upkeep. Best 7500$ I ever spent.

iv owned turbo vehicle in the past its definitely gonna have oversized intercooler i won't be racing it and burnouts act... not that it'll cost this but just for example id rather spend 20k on proper instal and all proper parts then spend 15k over time on parts and random upgrades after parts fail i am leaning towards turbo setup but hoping to get some insight on how these motors react towards the 2 setups

In my experience turbo guys always seem to have more problems. They seem to be rebuilding engines constantly. Turbos do make more power and it's easy to turn up the boost. That may be the contributing factor, they want a little more boost and pop there goes the motor. I don't know how strong the new 8 speed's are But usually as stated above the transmission gives up first.

Looks like the Magnuson blowers are the preferred form of boost from the tuners perspective. These are what Black Bear recommends and they are the resident GM experts!

 

Relatively simple bolt on for a decent power gain.

It was posted on here somewhere, but iirc I think they said the 8 speed can handle somewhere around 750lbft of torque. Horsepower I'm not sure.

Horsepower is an arbitrary number. You have to see the torque everywhere.

 

HP=TQ x RPM / 5252

You're right.

      Fluid Change Questions

      By Chuck FB · Posted

      There would be one way of determining the quality of the factory oil although probably more than a typical oil lab test, and that would be to draw out some oil from a new truck and send a sample to a lab that could do a more elaborate test of the oil. The issue with too little oil in the diff may not be the lack of lubrication of the diff bearings and gears themselves ( although a lack of oil volume for cooling ) but the wheel bearings because at some point the oil would be too low to properly get onto the spinning axle or fed along the axle tube. That was the claim by the local dealer from a couple of trucks in recent years that had the wheel bearings fail and they figured from lack of sufficient oil due to a severe underfilled diff and some of the bearing material made its way to the diff and it got damaged as well so the axle housings were just replaced on warranty. But your right that if the diff is over filled by whatever margin that it causes more churning of the oil than is desirable and that is no good either and can cause a pinion seal to leak. Also old oil I believe can tend to loose some of its properties like antifoaming and another good reason to change the diff oil every so often.

      I would be surprised if the diff's were not filled (with the cheapest gear lube) at the axle factory before being shipped to GM.  If you ever watched them building trucks they install the axles and all suspension parts with the frame upside down and then turn it over before its time to install the engine.     Too much gear lube in a axle can be worse than not enough especially with a lower quality GL where is get whipped up with entrained air (foam)  weakening its ability to lubricate.

      This is the 6.6 gasser section of the forum, you should either delete or modify your previous post as it is misleading for anyone looking for factual information on their 6.6 gas engine.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Well....I've done my first intake gasket. Probably wrong, but...we'll see?   Ultra black on the china walls and 1/4" up onto the sides of the intake gaskets. Permatex High Tack (couldn't find Gaskachinch) on the head side of the intake gasket. I read wrong and it says you're supposed to put it on the mating surface of the head, not the gasket. Hoping it's like a PB&J sandwich where it doesn't matter what side the PB goes on so long as there's jelly. That crap is messy/sticky and I got a dab or two on the intake port openings, tried to wipe it off. Hopefully it won't be a big deal and will only aid in sealing.   Per instructions I left the intake (top side) of the gasket dry except for a light smear of RTV around the coolant ports. Wiggling the intake in there was a bear but I had help to free me of surrounding wiring/stuff but I was basically able to set it straight down lined up with the bolt holes.   I did not think to wait until the RTV skinned over but there probably was 5-10 minutes while it sat before installing the intake.   Bolts finger tight first. Then, followed the Chilton's manual pattern to snug them to 15 lb-ft.   Waited a little over an hour, and then did the final torque in sequence again to 35 lb-ft.   Yesterday I replaced the fuel pressure regulator and got my new "nut and bolt kit" (fuel lines) installed. Damn GM used security torx on the spider, which I don't have, so I got scammed at the local HW store for an off-brand security Torx bit set.   The new driver's door mirror arrived yesterday, so, there's a chance this thing could be running and road legal tomorrow? I don't want to get my hopes up.   This will be my first time stabbing a distributor, too. Although, lucky me, someone else marked the old distributor for removal previously, I did see that. (Someone's been here before!!). Engine is still at TDC so it *should* be just a matter of transferring the mark to the new dizzy and rotating it into place.

      2027 GMC Sierra: Official Discussion

      He has his dad’s newer truck he’s put away. He has several old cars he rotates between him and his family. I’ve seen a restored square body and a SS Chevy truck he’s sometimes drives. He did raffle off a new suburban recently. As much as he is watched if he drove new stuff as a rule we’d know it. It would be fine by me. I don’t care what people prefer. I got one more new one in me. I’d rather my wife get one. I can’t get her out of the Genesis. Don’t tell anyone. I want her to get an electric truck. I want to put a generator in the back. Just because. She hasn’t bit yet.
