LSX Turbo 2500 Truck - Pulling a 15K trailer!!! 

You can buy a diesel for 10k. Just leave the truck stock so it stays reliable. That’s why you buy gas anyway, not for power.

Don’t get it mixed up

@@sugmaball5383 you buy a diesel for 10k and it’s gonna be a rotted shit wagon. Clearly you aren’t in the market enough to be knowledgeable about pricing these days. Everyone thinks it’s worth it’s weight in gold. Vehicles with bad trans or engines are pulling 7-8k. Not a shot in hell your getting a good diesel for 10k. Don’t get it mixed up.

Get a truck with 6l90

It was supplied by our customer. I am unsure of the brand.

Yes. It's a catch can/over flow tank from snail fab on FB.

Seems to be perfect where it's at for a reliable workhorse!

Custom BTR cam for the setup.

Truck is right around 6k. It had about 800-1000lbs of salt in the bed. Truck was 6940lbs, trailer 5660lbs, skid 9900lbs. Truck+trailer=12,000lbs Trailer+skid=15,560lbs Truck+trailer+skid=22,500lbs

How well does it do pulling more than its factory rates for at 12k? Mine is an 07 classic regular cab 2wd 6.0/4l80e with a 4.10 gear. Only rated at 10k. The 2wd reg cab has the highest towing capacity out of all the body styles. More the truck weighs, just subtracts from gvw. 16k gvw for these trucks.

@@dickbrugh5562 That's just the factory rating. I've pulled 12k with a 03 extra cab 2wd 4.8L/4L60E, 3.73 gear. Just had brake controller, 10 ply load e tires, air shocks in the rear and hitch with anti sway control bar. That's about 3 or 4k more than the factory rating with the small LS and weak transmission, small brakes and small rear axle. Didn't go down mountains but did several 800 mile round trips along the I-10 and changed the trans fluid more often.

Stage 2 summit cam and a S475. Keep the stock stall. Stock 862 heads from a 4.8 if you want cheap factory power.

@@Scramspeed where are you guys located?

why did you say keep stock stall?

@@zackariacherif1078 helps keep Temps down on the transmission

Yes it currently has a Jakes 4L80E that has been treating him very well. Only hickup we had was trans temps due to the converter. Had to install a massive setrab cooler and it seemed to do the trick.

He doesn't best on it but it definitely is a work horse....

@@Scramspeed Do you know what cooler he went with?

How much converter does he have here?

Yep, but I think he needs the bed free for snowplow duty.

It's a custom billet triple disc from jakes performance

@@shwab8what converter is it? 310mm or 265 and what stall speed?

​@@jacobwortman916 i can't remember. I called them and told them what my goals were and they built it to suit.

Chose a setup that makes power down low. Stick to a truck cam, i think texas speed's stage 2 truck cam is the most you can go before it sacrafices low down torque and still makes more power up top when youre not pulling something. Pair it with a smaller turbo, something that spools quick down low but dosent choke out when youre really reving it out. Youre not going to make as much power as someone who went balls to the wall but itll make useable power down low and still be a lot faster than it used to be.

BTR truck Norris with whatever turbo. I just know that cam will be awesome with an application like this

It's just hard to justify supercharger money when you can literally turbo a truck for half the cost. Even less than half if you fab up your own merge using the stock exhaust manifolds etc. Heat management with a screw blower is another issue. I can imagine IAT's towing with one would be pretty spicy. Those sandwich type intercoolers work well. But they're expensive as hell and make the SC sit really high up. As for fuel mileage I can imagine it's not great. I'd be surprised if it's getting 10 mpg once it gets into boost.

Agreed with the other guy, turbo setup is cheaper and imo better optimized for heavy loads. S/c is rpm dependent but turbo is load dependent. Both will make major torque but the turbo is kind of more fluid and wont be as inefficient at low load/light cruising.

@@FastPaull , something to ponder.

@@FastPaull hell, I'd be happy with 10 MPG with my stock 2004 2500 6.0L silverado.

It’s been done a million times

Where the factory manifold would connect to exhaust.

Yes, it has aftermarket cam and heads. I don't recall on the radiator, I will look int it!

4l80 more than likely. I have a procharger on my 2500. Pass everything by the gas station

Sorry for sleeping on this, it has a built 4L80 transmission.

The owner of the truck detailed all the weights of the truck, trailer and cargo in a previous question.

"Truck is right around 6k. It had about 800-1000lbs of salt in the bed. Truck was 6940lbs, trailer 5660lbs, skid 9900lbs. Truck+trailer=12,000lbs Trailer+skid=15,560lbs Truck+trailer+skid=22,500lbs"

@@Scramspeed Well scale was weigh off or he had something else going on because nearly 7k lbs for a single cab 2500 is way off. Even a 2500 Suburban is going to weigh maybe 6k. A 1500 will weigh about 4500 lbs and the main differences between a 1500 and 2500 is the rear axle (about 200 lbs heavier), more leaf springs (no more than 60 lbs) the driveshaft (15 lbs), a 4L85E trans (85 lbs heavier) and front end about another 100-200 lbs, radiator and HD cooling maybe another 25 lbs.

"It had about 800-1000lbs of salt in the bed" Boom

Not any more difficult or time consuming than typical swap stuff. It had a few teething problems like every serious custom build does, but nothing major.

Supercharger would likely be cheaper and easier, and give good low end power. You'd be paying for it in gas mileage though. I'd personally go turbo

The residual draw is not worth it

Well, I know fuel economy is largely dependent on driving habits. Lets just say mileage probably isn't as good as it could be.

This is a custom 4" stainless setup we did for him.

Its tuned for the winter plow season. When the weather turns for good we will see what it makes on E85 and more booooost.

@shwab8 , I'm looking at dropping a 408 in my 2011 Silverado. But, with a Whipple supercharger. Have you checked your overall mpg when towing?

@@timphilmon8573 I don't really keep track of it. I'd say 6-8 in stop and go pulling a trailer. Obviously how much weight your pulling is going to change it also. I've got a heavy foot so that doesn't help either. Once you get up to speed and the convertor locks it drives pretty normal!

afr 225 mongoose heads

If I had to throw a number at it I'd say somewhere around 700 to the wheels.

It made right around 650rwtq on 12psi. The heavier the load the more load the turbo has. In this video it drives a lot like a diesel. About quarter throttle and its at psi pulling that much weight. Once up to speed it's back in vacuum driving like stock.

Cool build but he is probably getting 6mpg on a good day and gonna have no longevity

You have no idea what you're talking about. The setup is built specifically for what it has. Forged internals, etc. People with clean, well put together combos, like this, know what they're doing and know who to reach out to to further back what they're doing. You could tell what kind of build it was when he opened that hood and again when he did that pull to 70. ​@lucaparrillo6474

The owner said "Depends how you drive it". Not many. We did not build this truck for mpg.

Customer did not want too much torque down low. When it has the plow on the front and salt spreader on the back he had concerns about just spinning immediately when trying to push snow. Decided to keep a higher RPM intake to keep the torque soft in the lower RPM area.

No meth on this truck. He has an intercooler from a duramax truck to keep the IATs cool.

@@Scramspeed would you say that intercooler is a reliable route for someone turboing a 3/4 ton 6.0 truck that does haul?

@@jaxonrickman5097 Well, he has been driving this truck for quote some time. Pulling and plowing with it, with no issues. In this case I would say definitely yes.

@@Scramspeed thank you for responding so quickly!

He didn't want to much torque down low. He wanted more up top.

@@allanb3222 More torque up top? He isn't towing at 5500 RPM. When you're towing, you're lugging the engine, you're nowhere near the efficiency range of that short runner intake manifold. I doubt the camshaft is even correct for that style of intake manifold.

@@FastPaull He wanted more Hp up top like he stated. Not torque.

Runner length doesn't matter much when boost is involved.

@@travishanson166 lmao yes it does. Go watch any Richard holdener video

Yes

@@shwab8 how quickly does it spool?

Depends on how much weight it has behind it. If it's just the truck it has some lag. With the weight of the trailer in the video, it's basically instant.

truck had 1k lbs of salt in the bed. 2 passengers plus 1k salt, truck probably sits around 56-5700. pretty close to stock.

The truck weighs right at 6k with me in it. It had around 800-1k of salt in the back during the video.

There was gear in the bed, that added additional weight to the truck.

​@@shwab8 6k for a 2500hd single cab short bed? Find a new scale.

​@8SecSleeper they don't make a regular cab short bed 2500hd just FYI. Toolbox full of stuff is couple hundred pounds. Plow bracket is a 100lbs. The turbo itself is probably 50+lbs. Has a big intercooler.... this isn't a stock truck at stock weight. It's also 4x4 if you happen to miss that too.

4x4

The customer specifically wanted the high ram to knock some torque out of the bottom end. Half the year this truck has a snow plow and salt spreader attached. He claims it is nicer to push snow with something that doesn't make instant torque to just spin the tires. Plus it looks way cooler.

@Scramspeed it's his money

Cost the same as a buying brand new regular cab 4x4 2500 gas truck.

@@shwab8 An engine build like this is not more than a 40k truck. 😆

@@allanb3222 I was referring to duplicating the truck. Didn't realize he was talking about just the engine.

Keep your foot out of it 12mpg. Like the sound of the turbo... 8mpg

Mpg lol

Yeah and the trailer is probably close to 3k

I have a gooseneck 24ft it weighs 5,600lbs

Yeah who say gas can't pull

No doubt!!

I’m doing just that! Lol I have an lbz duramax, but I just bought a 6.0 truck to turbocharge that’ll replace the lbz. Diesels are just to expensive to maintain in my opinion.

Hell no....that thing will never outlast or out pull a diesel, especially doing it efficiently. Diesels are way more robust and provide that torque you want way down low, but to each their own.👍

@@2015_Rubicnn 120k mile one owner truck, one month after I bought it from the original owner it needed a full set of injectors that cost me over $5k. I can build a complete 6.0 lq4 for that price. Lol

No I won't say that you have to also understand they were using Big blocks back in the day for buses and dump trucks and duallys back then a lot of them had gas 396 or 454 Big blocks in they were pretty rugged and last a long time in can take a beating. for instance my uncle had a Chevy Silverado 96 with a big block in it that thing pulled a three car hauler like it wasn't nothing the engine was rebuilt but it was pretty strong. The only thing a diesel may have advantage is torque in gas consumption you take that turbo off of it it's just like a gas motor. Turbo gas big block like a 454 or 502 it's a different ball game when it comes to the pickup truck class

@@williegohard1368 none were boosted either, like I said won’t last long not to mention I pull that with an f150 lol

@@freedomisntfree_44 yeah but if he was pulling a heavy load with it all the time of course it won't last long but just lollygagging with it like a daily driver pulling heavy here and there I don't think it would bother it at all if he's not hard on it

Not to mention it could be stock internal so imagine that he was to build the bottom end to handle that it would last even longer

I think you a diesel fan

Truck is right around 6k. It had about 800-1000lbs of salt in the bed. Truck was 6940lbs, trailer 5660lbs, skid 9900lbs. Truck+trailer=12,000lbs Trailer+skid=15,560lbs Truck+trailer+skid=22,500lbs

Went back and looked and yep at 1:33 of video....that's gonna light someone up who ever touches that
