I tow constantly with my factory cam turbo 4.8 Silverado. In fact it's a small 67/65 .71ar turbo and it makes really good torque under 3k rpm, way more than the 6.2 in my Denali
Hey Richard, I just finished watching this video and thought it was excellent. My knowledge of turbos is almost null. Pretty much everything I know about them I’ve learned by watching your videos. So far I’ve learned that if you’re wanting say 550-600 HP from a small block V8 they work pretty well with almost any cam you’d like to use in it, especially a cam that’s closer to stock than not. Running a turbo also requires a piston ring gap of .028” - .030”. And apparently the amount of boost is turned up somehow by turning something that clicks, I guess like a dial of some sort located on the turbo itself. Stock exhaust manifolds should be fine as long as the inlet and outlet to the turbo can be routed properly and waist gates are put in place preferably in bends. Also, higher octane fuel should be used to decrease the chance of detination. You have already answered several questions I’ve asked on a couple other videos and I thank you and really appreciate it. I still have a few more that I’d like to find out the answers to if you are willing to answer. I have a 2014 Ram 1500 4x4 with the 5.7 Hemi (completely stock) with 8 speed and 3.92 gears. As far as I know the only modification so far is the muffler is a Magnaflo. From all the information that I’ve learned so far, I’d have to have the heads removed and the connecting rods loosened from the crank to get the piston rings gapped properly then put back together in order to safely run a turbo. Is this correct, or at least the right direction? Then I’d need to add larger fuel injectors as well as have it tuned to support the changes including maybe adding more fuel pressure to boot. I am just trying to decide how the most affordable way I could achieve a goal of around 450/500 rwhp. Meaning by N/A, Blower/Super Charger, or, Turbo. Then my last question is do you think my stock transmission will hold up to it? This is my daily driver and I would not be abusing it. I would tho like to call on it from time to time. Thanks again.
Just remember get the exhaust side as big as possible with a small compressor it doesn't make much of a difference for spool on a big displacement engine. Like a Borg S463 would be perfect for a 4.8 with .90 A/r or so would spool really quick and not choke up top .
So if I’ve got a 6.0 bored .030 over it doesn’t matter that my S475 turbine outlet is necked down to a 3”? I’m running a BTR stage 1 turbo cam. Just wondering which would be the most cost effective upgrade to get more power, besides turning the boost up obliviously. Which I’m at 12 lbs now.
If your thinking about a Busa and can afford one even it is got some miles on it GET ONE. Best sport bike I've ever owned. They are actually comfortable and obviously really fast. They way they deliver power is so smooth it almost doesn't seem that fast until you look down at the speedo.
Hey Richard could you make a video with the torque storm with a wastegate and a smaller pulley to show the gains in torque compared to the torque storm without the wastegate.
The ebay gt45 is really close in size to a garrett gt45. Garrett uses the first numbers to denote turbine wheel size. All Garrett gt45 turbos have the same sized turbine wheel. Its 86.7x77.8 mm. The eBay gt45 has a 88x77.5 mm turbine wheel. Its so close it might not make a difference. I also have a feeling if you measured the ebay variants they will not all be the same, some of them list a 87.4x77mm turbine. A Borg S410 has a 87.4x77.9mm 10 blade turbine and is where my money is on for the source. Garrett has about ten million different compressor wheels and housing though, you really need to pay attention to the size and trim or pn if you want to know what wheel it is. The eBay turbo has a 69x98mm compressor and i dont know for sure but it looks like a copy of the HX55 that is 69.3x98mm. I cant find an OE turbo that is this size exactly but the Hx55 compressor is really close and might be what its derived from. Even the Hx55 turbine is really close at 85.8x79.6mm. Its more than likely a lash up of obsolete equipment. The dies used for older cast equipment get sold,maybe even as scrap, and mailed to china to be melted down into paperclips. When some of the equipment arrives it is salvaged and put back into service. Since this isnt licenced, they dont come with technical drawings or manufacturing aid and the parts get put together so they work. These turbos are absolutely the size of a Gt45 as most are assembled. There are odd Gt4508 that you find in the performance envelope but for each one of those there is probably 1000 gt/gta45 turbos that live daily on diesels. These have a compressor wheel about the same size as a gt4594 at 70.3x94mm and bigger than a gta4594 at 62.3x94mm. The Gt4502, gt4508 and their billet ball bearing brothers are slightly bigger but the difference is actually quite small.
@@richardholdener1727 the only reason I could see someone wanting a compressor map is if they are cross shopping brands or have a specific target in mind. Guys like that usually aren't looking at a sub $200 fan made of mystery meat.
Hey Richard, I’m building a work truck (75 c30 with welding bed loaded up 7500 pound curb weight nv4500 transmission 3.54 gear) and I want maximum mpg on the highway with low rpm torque for towing (380-400 lb ft) and 87 octane, trying to decide between 4.8 with a tbss intake and a small single at about 4-5psi, a 5.3 with a torque cam and tbss intake and longtubes, or a 6.0 with tbss intake and longtubes, what do you think? Leaning toward turbo setup just because it can be turned up if need be but I’m not sure if it will run on 87 octane at low boost and 93 would defeat the purpose (have all 3 motors so that’s no issue)
When I've had rooms so cold that I've been turned down every time I've went ahead and ask them again just to be a Jack ass And made a joke of it and actually a lot of them l decided it was OK to go ahead dance with me just because I made a joke of it. 🤣🤣😎😎
I've been watching your videos to try to figure out what turbo to run on my gmc motorhome with the olds 455 motor, I never get it over 3000rpm, I run through the mountains and could use more torque, I don't care about hp. There was a guy I ran into on fb who had one that was blowing through a Rochester quadrajet but he really didn't know what he had or why it worked as he never installed it. And there was another guy who had an ancient turbo kit he never installed. And he didn't know anything about it either. It seems to me that a turbo with about 5 lbs of boost would be great, going too hard will probably blow up the transmission in the mountains
I have a v6 262 2014 Silverado 4x4 tow dose any one no how big I can go on can with out messing with heads and were it will not float please help my truck is weak
Going to need a tune. Hpt is a source. Cam size we can spec you a custom grind for your setup. Headers help and a mpi swap over from the spider injectors. (Gives you choices for injectors) spiders are fixed.
The 2014 should be the EcoTec3 not the vortec. The V6 heads have the same port and valve layout as the 5.3l L83 as far as I know. I don't know how far your going to want to go with the camshaft, Gen5 cams are really pricy and they beat the piss out of the DoD lifters. I think the lt1 valvesprings work either way but it's dubious if it's worth it. I would do longtubes if you can, i dunno where you live and the laws are arbitrarily enforced, some kind of proper cold air intake and a reflash. The trucks have a really restricted intake and exhaust that keeps drive by noise down to a minimum but it also shaves some of the ponies. The difference between the 6.2l Silverado and 6.2l camaro is 35hp when the only difference is intake manifold, air intake and exhaust. The LT1 intake is better but not 35hp better, it's more like 8. You would be looking at several hundreds of dollars and a dozen hours to put a camshaft in and need a tune to make it play nice with the auto/ecu. On a 4x4 tow vehicle I do not recommend this. You will have to give up something somewhere, starting with your wallet for the cost and probably fuel economy. There is a good chance that towing with it will not change much either. It's a challenge to add 30ftlbs at 2500 from just a cam swap on a sub300 inch engine. I wouldn't be adverse to actually putting a turbo on it, other than transmission. If you are already in for a tune, headers and air intake a turbo is only a couple oil lines away.
I have my Ggrandpa's 64 c10, I like the novelty of a 4.8l = 292ci. Can I get good torque with twin turbos while towing and mileage while empty from the smaller displacement? Or am I splitting hairs......6.0n/a?
@@CobosDoesItAll you are better off going with an 80e. A stock 80e can handle way more HP than a built 60e. If you are building a street vehicle, then literally any stock 80e will handle 600+ with ease. If you are taking it to the track, then build an 80e and you can put 1000+ in front of it fairly cheaply. I have a 60e than can handle 800+, but it cost 5 grand to build, as opposed to a junkyard 80e that could do it with very little work.
man, if you wanna hoss the gas from 1800-3000rpm around town in your toy, put a set of 4.10s in it and hold on. you gonna think you got an extra 100 horsepower everywhere

E85 is hard to find out here in corn country. 87, 91 non oxygenated, and diesel is what is mostly available.

Do you a video discussing compression ? I dont hear you speaking about it much.
IT ADDS 3-4% INCREASE IN POWER PER 1 FULL POINT (IN THE 8-12: RANGE) LESS ABOVE AND BELOW THAT
