Wow, what a nice set up. I've got to think a supercharger Interferes less with the wonderful Busso exhaust note than would a turbocharger. That is plenty fast. It's not so ridiculously fast that you can't tap its potential without getting thrown in jail. I daily-drove a stock, mechanically excellent, low mileage, (38,000 when I bought it) black/black '85 for five years from 2000 to 2004. No major problems. Sold it to my mechanic when I moved to a place without a mechanic. I did much of the repair work myself, but didn't have the facility or patience to replace front donuts, etc. ALFA: Always Looking For Another.
Hey there. You should be an inspiration to anyone wanting to supercharge their V6 Alfa. Ver, very nice job. Thanx to you, and an almost new eaton M62 exactly like yours crossing paths with me, I have just finished supercharging my '84 2.5 GTV6. She is also rinning at about.25 bar, on the standard L-jetronic. At the moment not through an intercooler. I mounted my charger like the one in Greg Gordons kit, with a simple 2 inch pipe around the engine to the intake, with a blow-off valve.
Thank You! I use a modified electromagnetic clutch from a AC compressor to activate the supercharger. The M62 is almost too small for my engine so it is definitely better to go with a M90 for a 3.0 litre.
Amazing work on the fiber part fabrication, especially on the deck lid and handles, etc. Very nice car you have. I just got an 81 and getting started with it! regards.
@155stw Yes there are two throttles. The one closer to the air filter is always wide open when the supercharger isn’t activated. When to supercharger is activated this throttle starts moving opposite to the second throttle. It closes when the original one opens. This lets me easily control power and boost seamless with the gas pedal without any lag, really good for slippery conditions. When boost isn’t needed the air from the supercharger goes out true the N/A air filter.
reversed throttle body - thats brillant! Do you sell your carbon supercharger intake adapter? Actually thinking about doing the carbon part myself. Did you use a 3d printer for creating the mold? cheers
@hiperformancestore Fuel consumption is very important to me and that is why I made this supercharger setup. Thank you for all the positive feedback and for all the information about superchargers and water injection on your website. Today I measured the supercharger RPM to get the correct drive ratio. It is 1.91:1. The first throttle probably looses some boost, but I have made it really tight so I do not think it can leak such an amount that it would matter.
MY GOD! what a work went into this thing! Great job fitting the Supercharger! must have been hell of work figuring it all out! Loving the extra oilt Temp gauge The carbon must have been alot of work too! Bit overdone for my taste but seriously good work! Do you have a website?
@MaffiaAlfista I read your comment as positive :) I am not planning to lower the compression ratio now. We haven’t got E85 in Finland. I use regular pump fuel, 98 octane or V-power.
I used the second throttle position sensor as a switch to energize a single pole double throw relay. The relay was connected to the start injector in such a way that the start injector worked as it should during starting. The starting injector was constantly open at full throttle when I had the supercharger activated. But I would not advise you to use the start injector because your engine will still run lean.
Excluding the used blower I bought for 300€ I did not buy much else than the silicon hoses. I made most of the parts myself. I used the stock L-jet the first four years. I had the startup enrichment injector activated when the engine was at full throttle with the SC activated. It did run lean although I only had 0.2bar boost.
Very unique supercharger setup. Awesome carbon fiber work. It looks like you have a supercharger drive ratio of over 2:1 so it should have a lot more than 3.xx pounds of boost. I suspect it's losing boost through the first throttle, and probably some other locations as well. Overall Really impressive car. Check out my Alfa supercharging/turbocharging videos.
The clutch is a modified clutch from a Alfa 164 air condition compressor. The supercharger isn’t made specifically for Alfas. When I drive without the supercharger activated the engine breaths through the air filter on the passenger side. When the SC is activated air goes in through the driver side air filter. If the engine isn’t at full throttle all the surplus air the SC produces goes out through the passenger side air filter.
@madk4speed Thank you. The fuel consumption was around 8l/100km when I used the stock ECU. With MS2 it has been 7.4 to 8.2l/100km. This is measured on almost only country roads mostly with a speed limit of 100km/h. But it is hard to say if the mileage improvement is only because of Megasquirt or if there is an improvement at all. This summer there were too many track days to measure the consumption on a longer period than 350km at a time. Yes I am still using the stock ignition coil.
DIS ignition is an option for you, will give you much stronger spark, allowing you to play with the spark plug gap and various types of spark plugs. It could also give you a better mileage in theory. It's so easy to go DIS ignition. Why don't you give it a try? Also when you tuned your engine, did you focus in economy or power?
I also have an indicator light telling me it is fully closed. The rest of the system has been checked and does not leak. My supercharger is not in perfect condition and probably leaks internally between the lobes. The first throttle will soon be made completely air tight. My engine has been modified and breathes more air when driving full throttle without boost than an original engine. So the supercharger needs a higher drive ratio to make boost for this engine.
@Prelude2333 Thank you! The wheels are 15 inch BBS. What specs would you like to know? The oil temp gauge is a water temp gauge that I changed the icon on. The oil temp sensor is a water temp sensor that is located in the oil in the bottom part of the engine.
@madk4speed Yes I will make a distributorless system some day. I wanted to try this first. I focused in economy below 100kpa and in power from 100kpa and up when I did the tuning.
long time ago, but wonderful work,. I still have my milano looks perfect, latest photo showing as my avatar. Can we talk, like to maybe do a setup like that. Looking forward.
Nice work! With the supercharger off do you really get a better mileage with Megasquirt? Can you give us numbers on that? Are you using the stock igntion coil?
Hey,nice job you did there! kudos! I'm really keen to know how does the button activated supercharger work?! by the way,for a 12 or 24v 3.0 liter busso is it better to go with an M62 or an M90 supercharger?
Hi Alfatrimmarn, fantastic car ! What are the wheels and specs that you have on the car ? Nice setup with that oil temp gauge, can you explain how you did this, please ?
@Alfatrimmarn Again, very nice and original thought to do the oil temp gauge this way:) For the wheels I want to know offset, width and tire size, because they look a really nice fit on the car. I can't see, are they the original 5x98 pcd ?
Hey,you're welcome; it's quite an impressive job you've done! please tell me how much did the supercharging job cost you? ( excluding the blower. ) and is it possible to do it using the stock L-jet?
Incredible build. All that carbon must have saved a ton of weight on the car. HOW? did you make the door handles? you could go into business making driver handles-a much better improvement and harder to break :) Also, that is an amazing SC install. it is very ingenious how you use the N/A intake when the SC is running. What has been improved with it lately?...i guess i need to view ALL your video posts :) Keep up the GREAT WORK!
My blow-off valve sits on the pipe about 4 inches from my intake. Initially access air was vented to atmosphere, but obviously this was wrong, as my AFM (standard bosch) was before my charger, and this caused massive overfuelling in off-throttle boost conditions. I solved this by installing a return pipe from my blow-off to the intake pipe between my AFM and charger. Worked perfect. Bottom end fuelling good, but still under fuels at full tap. How did you connect start injector for full tap fuel?
@Alfatrimmarn The comment about your carbon work was meant to be positive but I see now that it can be misinterpreted. Just wanted to clarify that =) Any plans to lower the compression ratio and use more boost? Are you running on E85 now?
I can mail you pictures of my build, maybe uou can comment on it, and give advice. My layout is not nearly aesthetically as nice looking as yours with the beautifull carbon fibre, but it works OK..
+Matthew Neuforth Modified clutch to enable the supercharger to spin more than twice as fast as the engine. The benefit is better fuel mileage, no downsides.

Alfatrimmarn I have a 3.0L Gtv6 and am looking into forced induction. If we could talk I would greatly appreciate it.
Magnifique..so it's derivation with and without blower... Great

I almost want to guess that you make things out of carbon fibre for a living. Very nice and functional car!

@janussQv Thanks. Yes standard parts. Some have been slightly modified. Better clutch to handle the torque.
Amazing job! I understand that the engine internals are pretty much standard 2.5 v6?
@321Mobil I made all of my parts by putting in a lot of work hours. The complex parts required a lot of work. In the production I use heat and vacuum.
Your quality of work is outstanding. Do you offer any of these parts for sale?
amazed at the quality of the carbon parts. are you looking at making more at any point?
long time ago, but wonderful work,. I still have my milano looks perfect, latest photo showing as my avatar. Can we talk, like to maybe do a setup like that. Looking forward.

Those d00r handles are just pure sexxx. I have an Alfa 75, so I'd need four of them. I bet they're big-buck$, aren't they?
@Alfatrimmarn
The comment about your carbon work was meant to be positive but I see now that it can be misinterpreted. Just wanted to clarify that =) Any plans to lower the compression ratio and use more boost? Are you running on E85 now?
@DaKattila Kiitos :)
Hi, I was wondering how this car modified engine electronics (ECU) has been programmed, or what works on the Original folder?
Thanks
I absolutely love this car! Where is it now. and could it be for sale? Maybe? Yes? To say the least, I am very interested. thanks so much
Thank you for the comments. The car is not for sale.
@nathanviking No, I have not got a build thread on the car.
Would you be interested in making another bonnet?
Are there 2 throttles? How do you avoid boost going out N/A intake when the S/C is on?
How did you get all of those carbon fiber components?
can you describe how you have the air routed,
so you can turn on and off the supercharger?
hey there, looking at doing something similar myself, wondering if you have a build thread somewhere i could look over?
I can mail you pictures of my build, maybe uou can comment on it, and give advice. My layout is not nearly aesthetically as nice looking as yours with the beautifull carbon fibre, but it works OK..
You still make carbon door handles?
I have only made door handles for my own Alfa. Making carbon door handles requires a lot of work.
hi
have you got a build thread on the car?
Ciao auto magnifica alfa nel cuore... Le parti in carbonio chi te le ha fatte?
Hi, Thank you. I made all the carbon fibre parts myself.
Is that a carbon fibre belt??
No, it is a belt cover made of carbon fibre 😊
I make my own carbon components
What kind of clutch did you use for the supercharger?
+Matthew Neuforth the clutch for the supercharger is a modified magnetic clutch from a AC compressor from a Alfa 164 3.0
+Alfatrimmarn Does it hold up well? I'd imagine the clutch would burn up pretty fast.
+Matthew Neuforth I have used the same clutch for my eaton M62 since 2006. It has now done about 40000km and lots of laps on racetracks.
+Alfatrimmarn Holy cow. Stock clutch? also, what's the benefit of clutching it? I mean, as long as you don't stomp on it, you wouldn't lose much.
+Matthew Neuforth Modified clutch to enable the supercharger to spin more than twice as fast as the engine. The benefit is better fuel mileage, no downsides.
