Whipple supercharger help.

[Cucurú]

keep in mind that i have never owned a supercharged vehicle, nor done any major modification like this, so its worth double-checking what i say here. everything i mention is either stuff i have picked up from the forums or product pages.
if you are going for the stage 2, here are some things i recommend:
upgrade the half shafts, but not to the GT350 ones. the beefier aftermarket or Ford Performance ones.
VMP strut tower brace. they make one that fits over the supercharger so you dont lose any chassis rigidity. do note that this brace apparently makes contact with the hood lining, so VMP recommends cutting out a piece of the lining to prevent contact.
in fact, if you have an extra $1000, i recommend VMP's stage 4 supercharger kit. its a whipple with a different lid, plus comes with a carbon fiber intake tube, 120mm throttle body, 3.5" griptec pulley, and fuel pump voltage booster. you are basically paying $400 for all that because it also comes with the dual pass intercooler which already costs $600 extra on the stage 2 kit from whipple.
you can get all this stuff from Lethal Performance, too, so no shopping around at many different retailers.

here's some links:
Whipple Stage 2
VMP Stage 4
VMP Strut Tower Braces (towards the bottom)
Half Shafts

You know the new 2025 GT350 uses stock half shafts and stock oil pump gears? Seems everyone's gone cheap these days. What's next, 5.0 engine made in China?

I'm also trying to do my research on getting a supercharger. One of the speed shops in my area said I would also need the 10-rib belt kit, see link below. Is that a "necessary" or a "nice to have" because that is a chunk of change. Mine is a DD and auto.

anything that isn't in the base kit is nice to have. 10 rib just allows you to pulley down more aggresively for more performance. Since it's a DD, just keep the 6 rib and save some money.

I'd save some money for performance half shafts, not the cheaper GT350s. You'll need them for the power Whipple makes. Also a Mc Something or other Clutch. Can't remember it's name. If you plan on serious balls to the wall take offs.

I'd be curious to hear from people who have had the OEM halfshafts or GT 350 halfshafts to hear whether they have broken or not. It obviously depends on what you are using the car for. I doubt I will be launching the car at all, mostly roll racing and some road coarse action so I don't think I want to spend 2k on Ford Performance half shafts. There are other upgrades that are not as expensive as the Ford Performance, like the G Force. If a person is going full send and launching the car, they will probably have a lot of issues besides shafts, like busting the diff, clutch, and trans.

Launching the car/drag racing is usually where people break them the most. That amount of power + sticky tires (drag radials) + inherent wheel hop will generally cause the metal in the oem halfshafts to weaken faster than the aftermarket ones. That being said, there is anecdotal evidence on mustang6g about people breaking them even with a fully stock car and tires. Even then I'd imagine it was due to drag racing and not just daily driving.

It’s going to depend on what you use the car for. If are going to throw on slicks or drag radials(maybe), you’re changing the traction equation pretty dramatically and placing a lot more stress on the drive train.

On street tires, you’re going to spin quite a bit more; in this case, the tires are the ‘circuit breaker’ so to speak. But on drag racing oriented tires, where much more force is being applied in the drive train, you’re going to find the next weakest link in that circuit.

The beefier half shafts are always going to be good insurance but my bet is they’re not likely to fail on street tires except under pretty rare circumstances.

 

[8LAKK8UNSHINE]

Yes, launching the car on a tire is a factor I forgot to mention. When using a street tire that spins, it acts as a fuse and protects the drivetrain from damage. With a drag radial or a bias ply tire - anything incredibly sticky - now that means extra shock and no question the shafts, diff, and other parts will be under incredible amounts of stress. It's one thing to do a hit from a 40 roll; something entirely different to launch the car at 3000 RPMs

A guys Whippled DHs half shafts failed. GT 350 half's are for the power they made with the Voodoo engine. About $350 each is a bargain. I I had a 2025 GT Whippled with Ford Performance half shafts. Bought a DH Premium and sold the GT. Going to Procharger HO the DH for around town daily driving. The Procharger will kick in big on the freeway. My 6 Speed Tremec and 3.73 axle will help lots around town. The new Shelby GT350 Whippled does not have performance half shafts. If it does I did not see them on the Shelby's list.

I've seen some videos on Youtube showing the halfshafts. It looks like the GT 350 half shafts are solid and the regular are actually foam filled! The guys at Lebanon Ford recommended to me that if getting a blower with a MT car, get the performance pack, even just for the 3.73.

It's crazy to think that Shelby American is selling those cars for that price with the OEM half shafts.

Anyone ever heard of the passenger side breaking, or is it always just the driver side that busts?

There's a guy in one of the Whipple SC threads here who said one or the other failed. The Whipple is a beast on the bottom end, and could possibly tear apart a half shafts. I use my car in ways normal people don't, including drag and track racers. It's why I chose Procharger. Whipple can be hard on the engine, and if a failure happens metal goes into the engine, and bye bye engine. But for drag racing I'd lean more to the Whipple. Theirs a two vids in YouTube. Whipple supercharged mustang first drive reaction from a Pricharger owner, and Procharged mustang first drive impressions from a Whipple owne. And one I haven't atched yet . Best Ford Mustang. Supercharger. Twin screw vs centrifugal.
