Some time ago, some1 started a thread about an A4 with a supercharger. There was also a small, but fine video.
I need some technical informations about:
engine - stock or modified
supercharger - company?? paxton, vortech... ?

If im right, the A4 should have about 300 hp, right?? I cant believe that an 12v ( stock ) with the supercharger ( and 300 hp ) will live very long...

It would be interesting, because im gonna collect infos about modified 12v engines. Im going to help my engine with an supercharger or turbo...

Any infos would be helpfull!!

If I can't pronounce it I can't remember the name. I think you're looking for wnaudi12v? He had the video of his supercharged A4 rocket. What about Lachgas, tee hee hee?

But let me ask u something. Why r here so many people, who dont believe that its possible to supercharge or turbocharge "our" 12v engine?? I saw many postings with stupid answers and so on ( yeah, like "put naws into hit, haha " ). Maybe there are some peoples here who wouldnt be satisfied with the uncharged engine tuning ( like sharp camshafts or UrS4 mods... )( ok, i admire the work of UrS4!!! ). Is it to expensive for you, or isn`t it possible about emission´s and your law?? Or simply to much work??

Your answers would be interesting for me ( as little european :] )

Our Hitachi ECU cannot be chipped. So not only will the mechanics of the entire Supercharger setup need to be custom but some sort of aftermarket engine management should be installed for it to work properly. You'd probably be looking at $10k+ to do it properly and safely and most people here don't want to spend that kind of money on a car that is worth less than $10k. Also, since the 12V is many people's daily driver they don't want to take the risk necessary for a custom SC setup.

As for the sarcasm you read when looking through the archives, there is a company that claims to have a SC kit for the 12V but just ends up stealing peoples money and not delivering. He posts here occassionally trying to get people interested but we usually call him out.

 

I heard about this company.
There exists four different engine control units for the 12v. I have three of them at home, but havent compared them.
About updating the engine control unit, there is a tuning company in austria, who told me, that its possible. Yeah, i heard about the problems with the hitachi too. But they told me, if ill come with my v6 to them, they wanna read my ECU, and then ill know it. It should be much easier to plant a Supercharger and adapting the ECU than to do it with a turbocharger...

And i spoke with an Integra driver, he has 480 hp now ( after many many mods ), FWD , and he told me that it shouldnt a problem to take a free programable ECU and tune it.

So, my desicion has been fallen, im going to supercharge my baby. I think ill try it with an Eaton supercharger, because u will get them very cheap ( ebay ) here in europe, because we have a lot of mercedes slk 230 ;-))
And if this SC is to weak, lets try something else. But its a long long way...

If you r interested, im doing the lightweight- mod :-)) I have a few pictures, if some1 wanna see them. But let me warn you, there isnt much comfort yet :-)

I suppose it's the same. I think you call it Toluol. It boosts octane number and it well worth it if your engine runs better on higher octane. Many of the 1.8T guys add toluene to the gas.

 

I'm sure some people here would love to learn the differences between those different ECUs, part numbers, and especially differences in the wiring harness and electric connectors.

 

wnaudi21 (or something like that...)

I'd email him with your questions, I'm sure he'll try and be helpful.

Another member and I recently visited the supercharged A4, and it does indeed perform. AFAIR (as far as I remember) the engine was about 90% stock, with the only modifications residing in head work (P&amp;P, shaved maybe..?) The SC is technically a Motodyne product, HOWEVER!!!!, it needed to be SEVERLY altered in order to remotely fit ontop of a 12v engine. This is due mostly to the fact that the SC (ultimately) is a scam and is not intended to fit/work properly in the first place. Take my word on this, the only reason That particular SC happens to work is because wnaudi21 has invested soooo much money into it. The other inherent problem is the North American spec ECU... we need to re-map ours considerably for it to accept the SC. However it's likely that you wouldn't run into such logistic problems with a European ECU.

Apart from that, the air intake (upstream of the SC), fuel injection, pistons, crank, valves, exhaust headers (but not exhaust run), etc. are stock. I imagine that with the 3 big UrS4 mods (MAF, S3 hose kit, TB), the SC'ed A4 would be quite the fast machine. Exhaust headers too would help a great deal, as would larger valves. However I tend to agree that, in its current state of unmodification, this engine's life is undoubtably shortened (too much of an imbalance in one area...)

All in all it's a cool prospect and makes n/a 90's feel like turtles, but at this stage it's not practical or realistic for 99% of us "tuners." You can do whatever you like, but just be aware of the circumstances surrounding this piece of hardware before you get involved. Just a word of warning.

check yah later

 

It does look like the same SC that Motodyne is trying to sell, but wnaudi12v implied that it wasn't anything Motodyne.<ul><li><a href="https://forums.audiworld.com/12v/msgs/11020.phtml">I assumed by this post that it wasn't the Motodyne SC.</a></li></ul>

 

Although wnaudi12v told me not to say anything on the forum. He told me the entire story through AIM one night. I guess qPilot and Slowpearl got the same story.
