Does R3V want a m20 supercharger kit?

I applaud you for bringing the community together to provide amazing products. Sourcing ingenuity, quality design and fabrication from the core enthusiasts themselves, then bringing them to the consumer with amazing prices to boot. Brilliant man you are. Keep it up!

Easy:
- Charger where AC compressor goes, with air/air intercooler. Lose AC
OR
- Charger bolted to custom or modified intake manifold, with no intercooler (like Downing Atlanta's kit for the M42). Keep AC

Medium:
- Charger bolted to custom or modified intake manifold, with air/water intercooler sandwiched between the two (like most of todays OEM setups). Keep AC

Difficult:
- Charger mounted on driver's side, with air/air intercooler. Keep AC.


A kit that fits on the driver side, allows air/air intercooling and keeps power steering would be highly desireable. The difficulty here is accessory and idler/tensioner pulley placement and fitment, as well as fitting intake plumbing for intercooling. There is a bunch of room on the driver side, especially if the stock intake manifold is ditched and some of the electric components relocated. IMO air/air intercooling is a prefferable over air/water due to lower cost, better efficiency, less prone to heatsoak, and simplicity.


I suggest m90 because it is easy to boost down with a simple pulley change, then the owner can ramp up boost by changing pulley size as the engine is modded to accept more power. One kit for stock and modified engines. One kit to rule them all.

A passenger side charger would greatly simplify charge piping, at least it seems that way to me.
as far as air/air being more efficient and less prone to heatsoak, I disagree. air/water will give you much more even intake temps.

There's a few OEMs that use air/water, and if you build your hx into the blower outlet / intake manifold (although for a simple kit, that may over complicate things), you save a boatload on packaging volume and compressible air volume.

here's a few googlings I did:

real world examples of water/air: veyron, ford GT, ariel atom. All three near perfect examples of engineering gone right.

They even sell kits: http://www.frozenboost.com/product_i...5597fcb15d38dd
all you need there is an HX built to bolt onto your M90, and you're halfway done, and it makes keeping your AC much easier (thinner radiator = more room for stuff in front).
I'd pay a few hundred more for that over an air/air setup. I like my ps and ac.

It looks like i'll be looking for an m90 on the next 50% off day the end of this month.

I've been dreaming of a supercharger for my m30! If there was a m20 SC kit - I would have done that and kept the m20.

I know of a nice complete dinan turbo kit for your m30.

Interested!!

Why? Positive displacement and all that...

I don't know if you're looking for comments from the peanut gallery, so I'll just think out loud here for a bit.

I've had half a mind to do an electric AC conversion on mine, so if the AC compressor had to move to the battery tray, that'd be OK (my AC sucks down HP at such a prodigious rate I don't know how it doesn't overheat and explode - it costs about 2mpg @ 60mph, all the torque seems to vanish, and I can feel the torque surge every time it clicks off. FYI I managed to find a 12VDC, variable speed (0-5v control) compressor sized appropriately for a car), but logic seems to say "put me on the intake side with an air/water hx" seems that would simplify charge plumbing. Then I'd just do an electric PS conversion (steal parts from an MR2 or something.

Either way you go (AC compressor delete and FMIC or PS delete and air/water), I can work around it. both electric AC & PS are better for the track anyways, keeps the power sucking to a minimum by only pulling out what you need, instead of boiling ATF.

Now we just need to bump up the e30 alternator by a few hundred watts. Or replace it an go single serpentine belt.

The peanut gallery thanks you.

As long as it is not annoyingly loud/takes away from the nice sounds the m20 makes

Sub's

Have my charger and ecu, but would love a source for brackets, hoses, etc.

I decided 2013 is the year of the supercharger. Yes. GE will make a plug and play supercharger kit. Will have a plug and play megasquirt from whodwho and 5 ply silicone tubing by GE made just for the kit. Here is what i'd like to see. All welding will be done by Castro Motorsports. Siemens injectors will come from DMS. Brackets will be cut by Monkey Madness. CNC aluminum pulleys will come form RMS. Boost/vacuum gauges will be made by econo boost. Basically I want this to be made by the community for the community. If any of you guys feel your up to producing a component for the kit then i'd like to include you to. Denny that means you bud.

Still deciding on m62 or m90. May need to remove A/C or power steering depending on the final design. Will do everything in my power to retain all factory functionality though. Anyone interested in a plug and play 11psi kit? Price will be very low for what you get in true GE fashion. I'll be researching shops to get a steady supply of rebuilt units for those of you who don't want to or can't source their own units. I'm also interested in looking towards newer units off Mazda 929s, Mercedes c230, Pontial grand prix, new Ford mustang etc. May even design my own snub nose for the eaton blowers. I'll be getting a rapid prototype machine within the next 6 months so the possibilites can be endless. I have a local shop that does aluminum sand cast moldings but if one of you guys has a better in I'm all ears.

Yes I agree with the year of the Supercharger...Roots type that is. i already built mine from ground up over 6 months of work went into it.

I built it with a stage 1 and stage 2 approach. Stage 1 SC only and stage 2 being a twincharge setup. I already have all the design done and it looks factory (well almost). To keep costs down I used a lot of factory parts example E46 thottle body boots to accept the ICV and BOV..ect..

I would love to be part of this, I already in plans to replicate my brackets for the M20B25 and cobalt SS (M62) Gen IV supercharger.

I also have the tune almost perfected.

Community would greatly gain from this initiative for sure we need more Roots SC, the low end torque is really welcomed :) on these motors

[jules325i]

Yes We do.

Are superchrgers ca smog legl?

Only if you have it C.A.R.B. certified. Not the easiest thing in the world to do.
