EDIT The crank probably really does spin the supercharger. Still just as CP as I previo us ly thought.

There’s no way that supercharger does a damn thing.

!!! UNKNOWN CONTENT TYPE !!!

That’s the a/c compressor that’s driving it.

yeah, er... what’s driving the A/C compressor?

that this is even close to a 50/50 NP/CP split reflects poorly on Jelopnic

Major CP,

From the post:

“JTSnooks Rob Emslie

1/22/19 8:38am

Is nobody going to comment that this car is clearly NOT supercharged? It’s decorative, and apparently the car also now no longer has A/C as the A/C pulley has been re-purposed to “drive” the fake supercharger.

1. The supercharger takes air in through the back and outputs it through the bottom - The bottom of the supercharger is currently 6" away from the engine with nothing connected to it.

2. The intake manifold is completely stock, and there’s not nearly enough intake plumbing to have made the supercharger some kind of weird remote system.

3. The “drive belt” for the supercharger is clearly connected to the A/C clutch pulley, which is driven by nothing. He rerouted the serpentine belt to remove the A/C (probably when the A/C compressor seized), then just added a couple little tensioner pulleys on the side and a small belt.

4. Even if this thing was hooked up somehow to the intake tract (it’s not) and the serpentine drive system (it’s not), in order to put enough force on the belt to keep it from slipping that little pedestal would collapse just from the belt tension.

Come on guys, this one is easy CP.”

Ah, but this way there’s no parasitic losses from the supercharger, or the AC compressor.

Brilliant engineering and here you are trashing it.

I first saw the pictures and was like whooooaaaaa that’s pretty kick-ass cool! T hen I had a...wait a minute...WTF? that can’t be doing anything....why the hell is the belt on only half the ribs of the pulley? that’s hooked up wrong on the front end and wouldn’t be sending any air anywhere on the bottom end!

I’m less concerned with the 50/50 split and more concerned that it was published in the first place.

You can actually see the belt going down to the crank pulley, so... it drives both the a/c compressor and the supercharger.

Now, as to any actual performance benefits, I make no claims. But it does, at least, appear to spin.

For everyone who says it's for looks, zoom in if you can at the base of the supercharger by the throttle body. There does appear to be a very poorly designed tube going to the bottom of the blower it looks like. I also voted NP. Not sorry.

Also, you can see the drive belt going around the crank pulley. The tensioner/idler pulley on the left as you’re looking at it, wouldn’t need to be there if the belt didn’t go around the crank from there. I lightened up a pic from the ad and posted it here too.

Still, massive crack pipe for redneck-engineered forced induction on an old Subaru known for head gasket issues in the first place.

And I was going to point out that the ad says ‘limited slip rear’ but isn’t this a Subaru? That’s like, the least of the issues here...

A/C pulley is still belt driven, it’s just not on the same belt as the alternator. You can see it’s belt shooting off at an angle underneath the alternator pulley.

Despite all the stars the main debunking comment is getting, I feel like it deserves even more attention. Tom McParland might want to pick up on this one and give this topic its own post. Because this looks like a great object lesson in car buying bamboozlery.

So how does the compressed air get into the intake?

Urambo Tauro > functionoverfashion 01/22/2019 at 11:41

You might be onto something there (although there’s still more to be explained away). Due to the unfortunate camera angle, it almost looks like there’s more than one belt reaching up to the alternator pulley. But that can’t be right. It’s gotta be hiding behind that idler pulley bracket, as you’ve highlighted. So does that mean there’s a secondary pulley behind the AC compressor’s main one? I’ve never seen an compressor take two belts, but maybe there’s more fabrication going on here than meets the eye. Unfortunately, this angle doe sn’t help much either:

Great question. All I can say is, it does look like it could spin based on the belt routing. Nevermind it’s the totally wrong width belt, or that the air might not be routed into the intake in any useful way!

functionoverfashion > Urambo Tauro 01/22/2019 at 11:44

I think you’re overthinking it. I think whoever did it was UNDER thinking it. But from what I can see if you look at the full-sized image, it looks like the outer belt goes to the alternator and the inner belt goes to the a/c compressor and up to the supercharger.

Again, beyond that, there are many, many other questions.

Oh I think I see what you’re getting at. I was still hung up on there being a short belt between the AC and supercharger, but it looks like the left side of the belt coming down from the supercharger pulley might be reaching towards the crank instead of the compressor. Really hard to see around that idler.

Um, the belt that goes from the crank pulley, to the AC, then to the SC?

You’re right now that I take a look at it. The crank will spin it.

You’re right. The crank does probably spin this.

Many questions remain, but at least it does appear to be connected to the accessory drive system.

Look closer:

The blue line is the SC belt routing.

Now look closer at the SC, you can see the outlet has a custom made funnel to feed the intake:

Now it may be cobbled, but it is functional, and likely a riot. Boost + high compression means this thing is likely making STI HP with more torque over a huge rpm range.

CalzoneGolem > functionoverfashion 01/22/2019 at 12:08

I wonder if the blower whine changes when the A/C kicks on.

Through the custom “funnel” coming from under the SC:

Eh, they took the time to put high compression pistons and a better bottom end in it, i t’s likely had better HGs put in as well.

1. Look closer, there’s a homemade funnel intake:

2. Negated by #1.

3. Again, look closer you can see the belt running around the crank, to the AC, then to the SC, and back. It’s all driven.

4. 6-8 psi should be no issue for his homemade pedestal, I’ve seen far worse setups hold far more. 6-8 psi can easily be held by simple tensioners, it really doesn’t take that much belt tension to hold at low boost.

That’s probably true. Still a lot of unanswered questions and what looks like “good enough” engineering

Eh, it’d be fun to beat around til it breaks, then re engineer it to be better.

I’ll bet it’s hella fun, I’d beat it off road and have no regrets.

I, uh... changed my mind. And it was too late to edit my comment.

You might have already seen the other replies by now, but that belt is apparently longer than it seems. You gotta look real carefully, but I guess it does reach to the crank after all. I’m still not happy about the belt/pulley engagement on the supercharger, but it should be able to spin, at least for a while. And there’s a chance that the ducting is actually hooked up too. Not an optimal setup, but it should have some degree of functionality.

I’m still voting CP, be cause that’s a sketchy setup and it makes me worry about the rest of the vehicle.

I’m fine with it being “functional” but the first time someone stomps on it I wouldn’t be surprised if that belt slips. There’s gotta be a way to get a pulley to match the size belt they have clearance for. I get they can’t get an 8 rib down there, but man swap the pulley then, i still don’t like this thing.

Hm , I never thought about it before but d o serpentine pulle y/ belt groove/rib patterns follow a universal standard? I know superchargers sometimes use a toothed belt (like a timing belt) but when it comes to your typical   accessory drive belts, i s the number of grooves /ribs the only remaining variable (besides length)?

If this pulley has th e correct groove depth/spacing , it seems like a new pulley (one with only as many grooves as the belt has ribs) would theoretica lly be just as likely to slip as this one. I guess t here’s just no easy way to “properly” fit this supercharger on this engine.

I suppose you’re right, if it’s in the grooves it’s probably fine. I think i’m just looking for a reason to dislike it.

It looks like they are consistent and only vary based on effective length and # of ribs.

Still plenty of reason to hate on it. With work that shoddy, it calls into question ever ything else that’s been done to the vehicle over the past 250,000 miles, especially all the other engine work . I wouldn’ t touch it with a 10 foot pole.

yeah overall the car falls into the “run like hell” category, which is worse than the standard CP category.
