DIY Supercharger?

[GreenS550]

Without being condescending, adding a supercharger takes more than you think. The bracketing needs to be perfect if run off the serpentine belt. This takes a LOT of R&D to make correctly. Then you need a head unit that has gone under extensive, long term testing. Then you need a tuning shop that is willing to do a "home made" blower tune. Most reputable shops will not touch this.

Then, after all this, you hope it works out right. The 5-8K for a setup seems like a lot but it is CHEAP when you consider the thousands of hours to make a good system work out correctly.

In the old days of hot rodding, like 50 years ago, when I used to mess with stuff, it was easy, cheap, unreliable and slow by todays standards. But the cheapness made it work out OK.

If you want to mod and need to be on a budget, get an old car to mess with. The newer Mustangs are too sophisticated to do what you want to do without the cash necessary.

You aren’t being condescending at all. The whole reason I posted on the forum was to hear other (more experience and knowledgeable) people’s opinions.

Do you know how exact the bracket will need to be? From what I’ve seen most of the supercharger companies mount the supercharger to the engine. Wouldn’t the bracket just need to be measured correctly so the belt is straight and tensioned decently?

And I agree, $5k-$8k for a supercharger is not bad at all. This idea is not just about it being cheaper but also for fun.

Ok, if you can give us a TVS 3.1 that will work with other pre-existing 2650 setups ie (harrop vmp Edelbrock) you may can sell that....

What? Not trying to sell anything or make my own kit to sell. If anything to goal would be to build my own and then share how to do it with others.

ok its my idea but i haven't started on it

Ah aight. You can find some cheap blowers people are using for electric turbos that make 700hp

If you have seen a centi, like the Procharger or Vortech, you will see that the bracket is very precise with extreme tolerances such that the belt is allowed to operate the parasitic pulleys, etc properly. This is not a design done in the garage, it is done CAD.
Your best bet would be to order a bracket from ESS, Procharger, etc and then modify it to work with your head unit. But, that bracket will be likely several hundred dollars and then the head unit must be properly installed. You will have to modify a blow off valve. Like I said, complicated and more importantly, difficult to tune. Remember the computer controls the timing of not only the spark, but the advance, independently of the camshafts as well, in some cases as the charge motion control valves.
On the S197s, several folks modified the GT500 5.4 factory blowers to fit their 4.6 or 5.0 but it was very complicated. Most of those that did it were not happy with the results.
On PD blowers like whipple, roush, kenne bell, etc, the intake and the blower assembly are designed together, whether one piece or a put together. Again, a CAD.
Your '15 5.0 is likely worth 20-28k$ and if you F up the engine you will be happy to have purchased a complete kit.
The other option is to keep your eyes open on Ebay. Find a high mileage engine/trans at a cheap price and modify it out of the car. But, again, it will run several thousand dollars before your mod.
Good luck!

If the bracket needs to be as specific as you mention then there is no point in buying one from another company as I would have to modify it for any blower they didn’t design for. I also have not looked into blow off valves and if they are complex or not.

The biggest issues you'd have (that are different than buying a kit) would be the mounting and alignment to the motor/serpentine.

There are people that have problems with belts and those are from kits that have been beta'd and R/D'd to fit.

Nothing is impossible, but in this respect, a turbo setup would be easier.

You'd have to fab up your own mounting solution/bracket for the blower, then all the belts and idlers necessary to create a functioning and high performance drive system. Could you just run a longer belt around the blower pulley? Sure, but if you want maximum contact on the pulley that means idlers, tensioners that provide enough tension (and flex) so the belt doesn't jump or walk under hard acceleration and hard off throttle, etc. Remember, the longer the belt, the bigger chance of issues, so you would have to consider splitting the accessories into a second belt and that complicates the balancer. Or you could just run a ginormous/long belt, that stretches a mile under load.

The rest of the stuff mentioned, tune, fuel, etc, can and has all been done through tuner kits.

Aside from the blower assembly the part that's most problematic is mounting and driving it so it always works and doesn't slip.

figure out what I would need to do to mount.

Complex prototypes of anything always costs way more than the actual product for various reasons. Especially for something like a supercharger. There is no cheap way of doing it that would likely end in a catastrophic mayhem.

The brackets for a procharger carb legal kit are so easy that I can make them with a grinder and a drill no problem. They are both completely flat and a easy design to cut. This is the two brackets bolted together. As anyone can see this design would be easy to copy

 

[GreenS550]

That's true, but you need the brackets as a model. And they're precisely designed so you need a set to replicate. You don't just make those out of the clear blue

Where does the bracket mount to on the engine?

I don’t see why not. If you just replicate the mounting spots and adjust the mount so that the pulley is straight with the crank pulley I don’t think it should be that bad.

This is two brackets bolted together. The back piece bolts to the engine with three bolts
