Remote Single/Twin Supercharger setup
Remote Single/Twin Supercharger setup Looking to put a unique setup in my 1978 trans am. Owned 7 others and want something different.
Idea is a stock displacement 4.8/5.3 built to be as bullet proof as possible. Then remotely putting 2 gt500 superchargers. Brand new off ebay a single one can be had for 900 thats oem m122 eaton unit.
I figure it would produce more boost then I would ever need while having zero boost lag, cost would be around the same or less than your normal s/c setups, and of course extremely unique.
I can fab the brackets, and tubing, and It would be a fun project for the wife and I to work on.
I have seen the thread of the single being done on a 3rd gen. I guess beyond space and the crank pulley what else should be taken into account that might not be obvious?
I was going to tube the compressed air into a fast 102mm intake, however a ported ls6 intake I have been told would work fine too. Was considering a intercooler however this would not be a daily driver so might only mount one instead of two. I guess im looking for some brainstorming help.
hood would be custom fab'd or a big ole cowl of course maybe try to retain the shaker hood and attach the s/c's air intakes into a custom made shaker piece.

Hmmm ill correct that typo as the ebay s/c is a m122 that im looking at.
found this while looking for info:

its an m90 under the hood of a 4th gen.

I looked at doing the same thing. I bought an m122 off ebay, then found a new tvs2300 from a newer gt500 for $1200 and bought that. If you look at the efficiency maps of a tvs2300 vs an m122, you could probably make more power with a single tvs2300 vs two m122s before detonating the engine to pieces.

I however am seeing all the tvs2300 units going for 6K+ part of the project was to be different while keeping costs down.
edit:
Also I have yet to find out if a remote mount setup is as efficient as if it was mounted as originally intended. I would assume the system wouldnt know the difference and I would just have to make sure the system is mounted in the most ideal spot.

Here is a tvs2300 for $2000. You'd have to watch for a while to get one cheaper but they do come up. They are rear entry for the GT500s.

I guess ill have to look harder and keep my eyes peeled. How much psi would a tvs2300 make over a m122? I cant seem to find that I also cant seem to find how much an m122 makes.
Edit
I have found that with the stock ford motor it makes 450-500 rwhp, more can be gained with a aftermarket pulley and porting the setup. I think that a 4.8/5.3 motor displacement is close to the stock ford motor 5.4/5.8 used with these from the factory.
I think the best intake would probably be a custom sheetmetal one to maximize flow

M122 and TVS2300 maps arent as easy to find, but M112 and TVS1900 are easy, and both just a little lower output than their two bigger versions. So if you look at an M112 map vs a TVS1900 map, you see that the M112 is max efficient at 62% around 9psi and the TVS1900 is 75% efficient at 9psi, which is much much better, but its for a very small area and very specific cfm. Turbos have a much bigger range of efficiency, thats where turbos are superior, you can raise boost and they can stay much more efficient. The TVS blowers have a much bigger range than the M blowers though, much closer to a turbos efficency except the robbing of power from spinning them. M blowers are pretty terrible really

Verdad Gallardo Thats sad to hear, as I have seen some pretty impressive stuff from the mustang forum with modifying a m122.
I am primarily looking at using a remote mount supercharger because its alot less expensive than a real ls1 supercharger.
Also Im looking at a supercharger over a turbo as the car probably wouldnt be driven daily, it would be driven on the streets probably more than anything. I have liked the supercharged cars ive had over the turbo'd ones. While both were fun I just liked the always at hand fun and no lag. Just push the pedal and go.
Edit:
I have found that m122 max safe and reliable boost levels seems to be around 22psi. This is gotten from several mustang forums so I suppose hear say lol. Now the real question is can i run two m122's at 14ish psi to get around 20 psi total? I assume two running at 10psi wont make exactly 20psi but maybe im wrong. Again I may be wrong too and that running two at 14psi would only yield a *** ton of 14psi air.
I also would be interested in if the pulley shaft can be flipped thus allowing them to mirror eachother(a very visual only mod)
UNFORTUNATELY I have spent alittle more time looking up about the gains from twin supercharging, and its nothing. Everything I read labels it all show and no go. Infact it would perform worse and overall make my life simply harder, more expensive and slower. So a single remote supercharger itll probably be. However Hopefully by the time I get the 78 ready for the build a tvs2300 will be around the cost of a m122 now.

well the whole idea behind this project was unique, and inexpensive(cue all the fi is expensive people)
A M122 that can put me into the 500rwhp range is roughly 900 new and 400 used id maybe need a throttlebody 50 used 300 for single blade, thats most expensive in parts its 1200 and ill just have to buy bracket pieces and tubing, along with a belt and a supercharger pulley maybe 400.
so im looking at $2300 total for easily 500rwhp and a very unique setup. Im honestly thinking of relocating my coil packs and placing one ontop my ls1. I already have a supercharger crank pulley and id just cut my hood. Mad max style.

edit: the more I research the more i want to buy a junk hood and slap on ontop my ls1 and just cut the hood for clearance. I have a supercharger tune saved for my car as it used to have a procharger. Run it around 9psi heck id bet atleast 150rwhp increase for about 1600 bucks if I went full ghetto retard with it.

O yea I've been thinking hard on the whole id myself, ever since I seen pockets remote mount setup in person when he had the m90 on it, but any way a m122 on a jy 4.8/5.3 would be fun as hell on the street even at about 500whp but hp ain't ****, the tq curve u would have with a roots style setup would put a big smile on your face

I think with a custom intake and singleblade intake on my car with the mods I have I could easily blow apart my stock rearend......lol
The id I had for a remote mount vs. the way others have done it is to leave the tb on the supercharger an use an a2w intercooler between the supercharger an intake manifold opening, this setup is like how the thunderbird supercoupes was done but they used a small shity a2a
If u can find video from pockets or someone else that has done the roots remote mount an has the tb still on the manifold/down stream to sounds like a damn firetruck chasing u all the time, the whine is always there

I say go for twin superchargers justfor the cool factor! I would also sugest looking at the 1990s Aston Martin Vantage for insperation. Aston used two m90 units I think that were mounted off the heads with a a air to water chargecooler.
