Basic whipped kit without much add on.... expect minimum around 8500 if you’re doing it yourself. I went a lil extra mile and in it about 12k. Now I wanna crank it up a lil more and I’m at 20k.... it ain’t cheap.

****** idk if I could spend that much that’s a heavy price tag for sure... maybe once I’m done with everything else. (And If my wife doesn’t find out )

That’s one badass upgrade though gotta give u that

The 6.2 whipple kit is on sale for $6,500 right now. Bolt on and go.

TVS is $5,900 and the Edlebrock kit is $6,600.

Prices only go up from there with add on's but if all you wanted was to buy it, install it and go you are a lot less than $8,500.

Little update so I ended up just putting in the whipple without upgrading the fuel system, decided i wasn't going to run E85,

and yeah the kit came with spark plugs that we gapped to .20 i went with a custom tune, i had them gapped at .32 or .30 as whipple instructs but the truck would sputter, so my tuner decided to go with .20 and the truck runs flawless also went with the 4.125 pullet which put me at 11pounds of boost

Man NOEL im in the same boat as you , what other mods and what power you put down?

Sharp truck dude! I am IN LOVE with those Kings. I bootlegged some on an explorer way back in the day and were awesome. I too am curious with what power you're making. We did a Whipple on a 2016 5.3 crew cab a few years ago and I don't think the guy that had the truck ever had it on the dyno. 11lbs sounds healthy! I've thought about dropping a pulley size on my procharger to get a little more boost but I'm at my fuel system's limits - mild cam/dod delete and long tubes do go a long way though! It is one thing I'd highly suggest to support your supercharger btw. Get rid of all the stock top end stuff and beg the wifey for a cam package, you won't regret it. Then while you're in there you go with lt4 HPFP and injectors

what are the pros and cons of a Whipple vs, the LT4 ??

lt4 = $1200 used, any idea if they are defective internally

I don’t think they’d be defective as much as it’s just a used supercharger. EBay has their surprises though! Yeah cost might be a lot less than a BNIB aftermarket supercharger. But when you buy aftermarket new it comes warrantied, everything you need is already there and you won’t have to piece a kit together. With an LT4 sc, once you get all the parts you need to do the swap, you’re in it for a small fraction less than if you went with a new, aftermarket kit. This is besides the fact but still something to consider.

Another thing to note is what aftermarket manufacturers do to enhance their designs from their competitors and O.E spec stuff (I.e how their designs dissipate heat/keeps temps down more, how much air they can move, how fast they spin, how much more power/tq they make etc.) as opposed to their competitors and stock designs. Whipple can also write the tune specific to your truck or give the option to tune it yourself and save a little money while the lt4 sc you’d have to find someone to tune your truck (or diy) and write a custom tune. I would highly doubt a stock lt4 map would work on the trucks. I don’t want to sound like I’m knocking on the guys with the LT4 sc setups because indeed they saved a little money and it’s unique. I can certainly respect that they found a source for everything and did all the work themselves to make it work but it appears you won't be doing a sc for $1200 given what is necessary to make it work.

If an LT4 setup is the route you’re looking to go down, it can be done. Unfortunately it doesn't look to be like it’s a ‘bolt on the sc, tune and go’ sort of scenario, it looks like some parts were needed and the charger needed to be modified to fit but it’s been done according to this thread: https://www.gm-trucks.com/forums/topic/238756-so-you-want-to-put-a-lt4-supercharger-on-your-l83l86/

I’m no expert and do not have a twin screw setup, so guys with these setups can drop in and give more a more detailed answer but I figured I’d chime in to show my findings. It looks like a cool swap. I’m curious to see what it runs on e85.

i understand the piecing together parts , not a problem, just wondering if there is a performance enhancement with Whipple vs LT4. I would be happy making 500hp dont need more than that.. is the LT4 SC capable of this?

update, LT4 conversion will run $5-6000.

Ohh my mistake. I mean given from the thread I linked above, I don't think it would be too far out of the realm to reach 500hp with the lt4 sc. He claims it made 483 but I didn't see anywhere in his thread about whether it was ported or not and what pulley he was running. Maybe on e85, ported and smaller pulley? Idk if you plan on running e85 or running lt4 hpfp/low side fp and injectors but I'd imagine your truck would want it. A cam paired with the supercharger should certainly get you there but I don't have the 5.3 either so I can only assume all of this.
