home made supercharged legacy wagon
 

today i dropped the vortech fmu for this guy that he bought from me on ebay, i didnt know what was under the hood of the legacy wagon parked in front of me, it has a cool little sticker that says: "you just got beat by a wagon :P " with the smiley and everything, i suspected..... after talking to him he showed me the setup wich is quite creative let me tell ya :y

the ac clutch wich replaces the sc pulley kicks in when he's heavy on the throttle and instantly rams 10 psi off a roll, i saw it revving up and the whine is loud too ;D of course 100% HM as you can see, and no the engine still runs without management, apparently hes putting the fmu asap wich i dont know if its gonna help on this kinda uncommon setup, good luck with the project :y

Well done young grasshopper

Re: home made supercharged legacy wagon
 

Ha! Sweet. ANy Idea what the SC is from?

What year Subaru? I'm trying to talk my fiance into a 98 or so Sedan.

Re: home made supercharged legacy wagon
 

that is a very interesting thing underneath the hood of a scooby.

Re: home made supercharged legacy wagon
 

damn. see. my friend had a set up like that :-[ it looked all cool. but no matter what he did. under any kind of high rev. the belt would fly off. he went through like 7 different types of pulleys. and it still flew off under high rev :-[ he tore apart atleast 3 different belts. before he gave up one day.

i brought up a thread bout a different super charger here.
https://www.homemadeturbo.com/forum/...?topic=50983.0

its a pretty neat idea. and i think it would kick ass if someone could custom fab one. it drives off the alternator pulley. and looks like its nothing more than just a compresser off of a turbo. alot smaller than installing a whole supercharger. but it gets less psi. bleh.

Re: home made supercharged legacy wagon
 

i believe it was like a 93, not so sure i asked a lot of questions but never crossed my mind to ask the year lol.

Re: home made supercharged legacy wagon
 

thats the M45 clutched supercharger isnt it?

Re: home made supercharged legacy wagon
 

Hey, Thats Mine! ;D

Thanks for the FMU Saxxu.

Yeah, it aint no turbowhachamacallit.

Its an Eaton M62 off a Kompressor series Mercedes. I upgraded my crank pulley to 7.25" so it spins about 2-1 ratio for 9-10 psi. Upgraded injectors to 370cc. Upgraded 6 puck clutch. Currently I have a 1-1 rrfpr which I TRIED to replace with the unit from saxxu, but it was too much psi (12-1, what was I thinking ???)

I went from a stock 100 whp (chp) to about 170-180 whp. I dyno tested on a mustang dyno at 152 whp but that was at 7 psi and 30 psi of fuel pressure and 3.5 spark plugs firing. I am dynoing again this weekend at Torquefreaks in Portland.

I went from a 16.8 average 1/4 et to 14.9. Best et so far is 14.7 at 93.

that looks tits 8)

Re: home made supercharged legacy wagon
 

Awesome work :y

Re: home made supercharged legacy wagon
 

You can use the 12:1 fmu but you need a needle valve to bleed off boost to where you need to be.

Re: home made supercharged legacy wagon
 

yeah im going to torque freaks soon here also, it's the only dyno close around here, not expecting much out of 5 psi but i would like to keep track of the add-ons and tuning >:D

Re: home made supercharged legacy wagon
 

ive never been to tq freaks, shoudl go sometime

Welcome to 5+ years ago on a Honda.........

Del Sol D15B7 went from 16.4 to 14.0

Pics arent showing up for me :(

must.....see....pics

Re: home made supercharged legacy wagon
 

what you put that super charger on a honda? did it work? and what size injectors did you use?

Re: home made supercharged legacy wagon
 

the NW crew should let us know next time there's a dyno day on either OR or WA, im looking forward to a car meeting

Re: home made supercharged legacy wagon
 

Does Merc use any bigger turbos? What's the displacement on that M63? 63ci? If so, it looks really compact, so if they have any other I assume they would also be compact.

Re: home made supercharged legacy wagon
 

How are you keeping belts on that thing... it looks like you mounted the m62 to the unibody. Doesn't the motorflex under acceleration cause misalignment issues? It's hard enough to keep belts on when a supercharger is mounted to the motor! Anyway, awesome to see someone get a mercedes kompressor to work on a car that's actually affordable. Those blowers go for ~$300 on ebay - a great deal if you ask me. Do you have the elictronic clutch hooked up to your TPS? Hope you get the fuel situation sorted.

Re: home made supercharged legacy wagon
 

I thought about doing this to an Accord but the obsticle that ended up ruining the whole idea is when I actually looked at the crank pulley and measured, crunched some numbers and even with the smallest S/C pulley I could find on eBay it still probably wouldn't spin fast enough to make any kind of difference.

However if I could get ahold of a custom crank pulley, it would probably be possible. I would call around and ask companies if they could do it but I don't have any money right now :D

Re: home made supercharged legacy wagon
 

The M62 moves .75 liter of air per revolution. The m45 is .5 liter, the M90 is 1 liter and the M112 is 1.25 liter.

The SC is mounted to an aluminium plate which is bolted the the top of the head. Subaru heads are milled flat on top with extra mounting/bolt holes. The I use two idler bearing for tension, max belt wrap, and to keep the belt from flopping/vibration. It does have an electronic clutch, which turns on when vacumn nears atmosperic. For now, I have installed the Vortech without the vacumn line, and reinstalled the old MSD 1-1 regulator in addition. This bumped my base pressure up to about 42-45 and on boost get about 62-65, which is actually about perfect.


I purchased an underdrive pulley off ebay for $60 then took it to a machine shop that specialized in alumium and had them turn a larger pulley and mount it to the existing smaller pulley. Total cost was about $325 OUCH!

Currently I am running a 2-1 pulley ratio, the crank pulley is 7.25 and the SC pulley is 3.625 diameter. Optimal/max pulley ratio is 2.5-1 which means I would have to get an almost 9.25 diameter crank pulley! This would give me about 12-14 psi max.

Re: home made supercharged legacy wagon
 

i like the duct tape on the intake ....mad hmt style

Re: home made supercharged legacy wagon
 

Thanks reddevil, I knew that. But that doesn't answer my question if there are any other very compact screw chargers like that M63.

Re: home made supercharged legacy wagon
 

Yes there are more compact/more efficient superchargers. Lysholm is the main maker of them. But I don't have any photos or links to support this. But.......They are almost ALWAYS way exspensive. They aren't common at all, so they remain pricey, even used.

Whipple uses the Lysholm technology but they are pricy even used,

Re: home made supercharged legacy wagon
 

Dynoed today at TorqueFreaks...


Well, I was happy my motor stayed together, but not so happy with the hp improvement.

155 hp and 175 torque on a DynoJet.

I expected a much bigger hp increase due to the extra 3 psi I now pushing, but only gained 3 hp. I did gain 15 torque though.

The torque graph was pretty amazing. 170 torque at 2700 rpm and stayed there until it started dropping at about 5000 rpm. The hp at 2700 was 90 and peaked at 155 at 5500 rpm.

At about 5700 rpm I would either max out the MAF or max out the injectors (or both) and would go dangerously lean. But since I shift right about there anyway and thats where the hp peaks, I am pretty happy.

I suspect I didnt gain as much hp as expected because the motor is lower compression than my first. I don't know how much, but since its not knocking at all at these levels of boost, it must be significanly lower. But then again, I suffer in percentage of hp increase per psi.

Now to just get some more boost.........

Re: home made supercharged legacy wagon
 

great job doug!, im sure the c.r. had to do with your hp loss, but in the other hand lower c.r. will be more boost friendly enviroment ;D find a way to make that thing spin harder :y or just find another SC did you ever considered the SC out of 89-95 supercoupes?

Re: home made supercharged legacy wagon
 

Thats an M90, and would give me a 25% increase in boost. Only problem is that I have not comfirmed that the snout of the M62 can bolt to the snout of the M90. The M90 uses a bypass throttle as the SC is spinning 100% of the time, where as mine is only spinning when I want. ie pedal to the metal.

Hey, we rented the dyno there for $400 for 5 hours. I paid $40 for three pulls. I could have paid less but didnt want to screw the guy who was setting it up. If you can get enough people together, its a great deal and a good time.

Re: home made supercharged legacy wagon
 

Any other problems with the MAF? I noticed the intake tube was shapped alot differnet than stock? We had alot of problems doing my brothers EJ20T/Vanagon swap when we modified the MAF tube.

FMIC is installed
 

http://www.vincentfurniture.com/phot...cinstalled.jpg

About 99% finished.

I have about 9 hours so far in the install so far.

1.5 hours getting the bumber off.

3.5 hours cutting sheet metal and aluminium tubing to fit.

3 hours buttoning up everthing, moving intake parts, cutting LARGE LARGE sections of bumber out, including the turn signals.

IF I was turbo, all would be right with the world. But no, I have to be different. The damn supercharger, which without an intercooler has minimal mounting problems, has SERIOUS problems now, meaning the intake and outflow are not even situated where they should be. In fact, the entire SC mounting setup has to be refabbed 100%.

However, I was able to get it cobbled together (in fact, it is already done) so that it runs and drives fine, but I lose 2-3 psi due to restricted intake and outflow. On the plus side, its now intercooled.

On the plus sides of things, the main portions of the FMIC and piping are generally where they should be, look good, and no serious bends. And when I actually get around to installing the 2nd supercharger, I would have to remount the orginal SC anyway, so now I just will be ahead of the game.

I took it for a test drive and POW, blew off a hose. Fixed it, and POW blew off the same hose. Luckily I was actually on my way to get some T-bolts. I bought enough for all sections but one (didnt count it, whoops) and of course, it blew off on the way home in the dark later in the day.

But, it works pretty damn good.

I reworked my side marker lights into turn signals while I was at it, and 100% installed my headlights for the first time since I owned the wagon!

Re: home made supercharged legacy wagon
 

The racing stripes are dumb as crap but aside from that, awesome setup. Get some video of that hoss.

Re: home made supercharged legacy wagon
 

nice

Re: home made supercharged legacy wagon
 

A little update on this project.

Currently pulling 14.5 sec at 92 mph ets at 7 psi.

But.....

Second supercharger is being installed over the next few weeks. Hope for about 14 psi, 13.4 at 102. (that is dreamland, but not too far off!)

Re: home made supercharged legacy wagon
 

don't go small :)

M63 in the background :)

Re: home made supercharged legacy wagon
 

The problem with the M90 is that is physically too big. AND it requires a bypass valves setup since it is running all the time.

And it only pushes 1 liter of air per revolution. I will be pushing 1.5 liters via the two M62s....Or so goes the plan.

The 2nd supercharger has been installed, but its not running yet. I still have to do a fair amount, such as relocate the battery, get more 2.5" tubing, extend the MAF wiring, and so on. But I will have one fast old station wagon!

It runs!

It runs poorly.

It gets to only 9 psi in fifth.

Poop.......


Three problems....

1- need a slightly long belt so I can get a tensioner on the 2nd SC side.

2- Need a Blow Thru MAF because....

3- Sucking air through 2 superchargers is hard work while superchargers are off and this would be solved by.....

4- Running superchargers in parrallel instead of sequential as they currently are.
