My winter project...

[Jason@JacFab]

The entire supercharger module sits inside the V shaped area between the cylinder banks, so the engine is fl at and meets pedestrian safety regulations. The total weight of the module is 39 lb (18 kg) (excluding coolant).

The power consumption of the supercharger module is between 2 and 50 hp, epending on engine speed.

Seems pretty light? Interesting info there?

Found this today... http://www.s4-mtm.com/images/925803_3.0V6TFSIengine.pdf

Lots of decent info about some of the workings, and systems of this Audi unit.. Aside from mounting, I'll need to figure out a proper pcv setup (That bung looking thing on the bottom of the unit is a pcv inlet into the super charger.), and figure out a way towork the bypass valve... Looks like it might just take a 0-5v signal to open close.

Oops, I must have forgotten about it and when I started doing more research when the Audi unit showed up today got excited again when I stumbled upon it through searching the interwebs...

So the stock Audi pulley measures appx 2.8", and with a 6" pulley on the LFX it should make about 7.9psi boost spinning the sc to ~15,451 rpms which would put it in about it's 65% efficiency range. I really feel like the 1320 is undersized for an LFX engine based on this math.

Seems like absolute max boost with a 1320 would be 12psi, and you'd be running the SC at about 18,200 rpms in about the 55% efficiency range.

Hopefully the bricks are extra efficient in this thing. I drew up and cut out all of the flanges I need for the intake today. I'll have to take some measurements off of the supercharger, and the engine to figure out the offset of the flanges to get the drive to line up, and then build some sort of fixture so I can begin trying to fit the tubes to the offset flanges.

Any progress?

I just don't see the 1320 being a good super for this car, seems like you'd be spinning the crap out of it. That 1900 wants to be used!

[Gee]

This makes me very very happy. You would have many buyers for this unit. It would be such an easy install and wouldnt need any supporting mods. Great work man.

I doubt the build will ever make uber power. But it will be a huge gain for a relatively modest investment. If it will fit.

True, but that's part of the fun of having a positive displacement supercharger... getting to pulley down for more boost. Which is why the TVS 1900 would be epic. Though, if this can break 400whp and, eh, 420 ftlbs, it is a definite possibility... Just, again, you'd be spinning the crap out of it to make enough boost.

I agree. I think this combined with with a small turbo charger, in order to twin charge it, would make for a more sustainable amount of boost. And it would be bad ass....

If you end up making the Audi piece work you could possibly look to just make all the supporting parts, lower manifold, pulleys, brackets etc part of a kit and have the end user source the S/C from a used parts dealer.

To put it plainly this will limit your liability. If you went new it would most likely end up too pricey. Going used opens you up to failures.

Just a thought. I'm watching because a Colorado might be in my future as a work truck.

One last thing I tried something similar for the old 4.3L in S10's and stopped when I realized that my target audience was broke. This audience is doing a little better. Good luck I think you might be on to something here.

Could this be a new thing for an LFX engine for a top mounted Supercharger ???
ah man this would be the best news ever.

None to report... It's a winter project... It's not going to happen over night. I'm still thinking about the best way to go about the intake manifold design/fab.

You'll never get huge boost out of it, but again, you aren't spinning the crap out of it ALL the time. In a normal drag strip run, how long are you really spinning the thing at max rpms? 3 seconds, 4? I don't think it's a big deal... Supposedly the 1320 max continuous rpm rating is 18,000. But I've read a few places that brief peak rpms of ~22,000 is safe, and it shouldn't come apart. So considering you're not just holding your foot to the floor in one gear keeping the engine at 7200 rpms... I could see gearing the SC to run upto 20-21k peak, which could raise the max boost up to ~16 at peak rpms...

I do agree, the 1320 is probably not ideal, but as previously mentioned, for a budget deal that's compact and self contained, It might just be worth the effort.

At the moment, I am really not planning on selling anything that I'm doing on this project. This is purely for my own benefit/enjoyment, but hopefully it will inspire some to think outside the box along the way... But we'll see how it all works out in the end.

Don't get me wrong, I think it's worth it. I think the main issues are how efficient the intercooler bricks are and how the overall efficiency affects power delivery. I mean, even if you are spinning the crap out of it, it is only at peak... I wonder what normal cruising boost would do to economy.
