Supercharged MP3 Build


Yeah nice car, I have seen some previous posts of yours from earlier and it helped with the inspiration for this project.

I have also seen the links to the kit from taiwan, but I never seriously considered it due to the costs as well as potential ordering hassles. Honestly if I was gonna spend the money on the taiwan SC kit I would rather just turbo the car.

As far as a status update:

Over the weekend I got an additional sensor bung welded into the exhaust because the MIL eliminator was not working for my 2nd O2 sensor with it being removed from the exhaust (wideband was in its spot). That is now taken care of and no more CEL.

For the last couple days I have just been driving in NA mode due to constantly maxing out the MAF from the tune on the ssafc. I can rev it to about 5 rpm in SC mode, but after that it will just throw a CEL. I will soon be getting wrx fuel injectors to take care of the situation. I will not switch to a msp ecu, and tried not having to replace the fuel injectors, but there is no way around it and I must do one or the other. I had tried to lean out the top end a bit to see if I could prevent having to send such a large signal through the MAF, but due to safety of the engine and even optimal performance I just need more fuel up top to keep the AFR safe.

After driving the car for a while now and doing some comparison, I am convinced the 5psi on this SC produces more power then 5psi from a msp turbo (or even the stock 6-7psi msp's run). I read some people saying that SC psi is less then the equivalent turbo psi, but I am beginning to think otherwise. I think even though the psi is pretty low the amount of air flow must be greater. I have driven in a almost stock msp, gli, gti, wrx.... and other similar turbo cars and the performance (power wise) just seems above or equal to all of those. Past driving comparisons as well as some "other" road testing has lead me to think that this car is quicker then I thought it would be.

Butt-dyno and speculation talk aside, I plan on actually getting a dyno done, as well as going to a 1/4 track probably sometime next month. My friend has a modded EVO X with cobb stage 2 @26psi that will be coming with me also for comparison ;). That thing is just a wild beast of a car, but surprisingly I still feel very happy getting back into my car afterwords (not saying that I would mind trading with him,lol).

I saw your video clip. It sounds powerful and nice. Actually, mine is not as powerful as I think after I installed it. I can say it just drives like a V8 3.0 sedan. That's why I'm thinking to increase the boost. One more tihng to share with you. Someone in TW did a SC+turbo project. I've ever read the brief introduction once from a car magzine, but didn't see any result afterwards. Here is the url for ur reference. http://www.gaibar.com/caroptions/opsample/2008-06-30/20080630100709_99643.html
It looks pretty interesting that this guy setup as low RPM for SC and then switch to turbo at high RPM.
 
Yep, that kit is offical. Designed by Taiwan company AAI motorsports and made by Japanese manufacture Ogura. when i installed it, it boost up to 0.45 at 195 hp tested on dyno (not sure exactly how much on wheel, maybe 180 something )beside SC kit ,everything else comes with factory at that time. After installed SC, I changed the high flow header, midpipe, muffer, and intake system. I believe it's alittle bit more than 200 hp now. My next step will be changing the size SC pulley in order to increase the boost about 0.7.

Hi mate,

with this kit from AAI, does it still retain the factory A/C?
 
Just for you US guys, I have found out that AAI Motorsports have an american distributor! :D

Here are the details:

709 E Cedar St.Ontario , CA 91761 , USA
Tel : (909)923-9188
Fax : (909)923-9108

they do have globally (EU, Asia, Austria and US.) They are actually Buddy Club offical team.
 
So I haven't had alot of time lately to post, but here is the latest info so far...

I installed wrx 440 injectors in place of the stock ones in order to address maxing out the MAF. Everything works great now. I can finally floor the car all the way to redline without maxing out the MAF, and best of all no CEL. I still need to work on the tune a bit at partial throttle because even at low rpm I sometimes end up getting full boost which I haven't had time to tune correctly.

Below are a couple pics of the engine bay. I haven't had time to clean the engine bay, but I will eventually (poke). I will also get some video once the tune is all set and done. If I can I might get a dyno next week since there is a good deal at a shop around here for another week.


Here are some pics to keep some interest if anyone still cares. No nice snail or intercooler, just a NA header and some piping.(wiggle)

pic 1-Stock green injectors, wrx blue injectors

pic 2-You can see how tight of a fit it is for the lower radiator hose. It barely fits, but since it is so close to the header I used some heat wrap to help against the heat just in case.

pic 3-The intake is very tight between the header and radiator. Slim fans are a must.

pic 4-If you look close enough you can see the SC in lower left. The uper radiator hose also comes close to touching the intake. I added some more heat tape to prevent rubing wear. Might eventually change to a different shape upper hose.* Bonus points for whoever sees the 2 different things about the bov.

Nice to see your updates. By the way, did you upgrade the oil pump (or use spring to increase the pressure) and the fuel press control value?

No, I did not upgrade the oil pump or fuel pressure valve. Did you have to do that with the kit you are running? This SC does not use any oil from the engine system so there is no specific reason to do this for my setup. I don't need to upgrade the fuel system because I am still well below the threshold that many other people are with there turbo setups and they do fine. The reason for the injector upgrade was to help fool the ECU and MAF signals due to how the SSAFC works, the stock injectors would still work fine in terms of how much fuel they flow.

My SC doesn't need oil either. The oil pump is for your engine not SC. The kit I got actually came with fuel pressure valve at static pressure, I can't change the pressure of that. My friend told me to better upgrade it to other brand of fuel pressure like Sard or other brand. They can manually change the pressure and come with the meter. Like this one http://goods.ruten.com.tw/item/show?21003114269605
For oil pump, you can either exchange the part or just use the factory part but just replace the high pressure spring to increase the pressure. Since the SC is already installed, rpm will accelerate faster. Therefore, I think higher pressure oil pump should be necessary to pump the oil with higher pressure. Some of Taiwan P5 owners just replace oil pump with JDM made product. They said JDM oil pump has higher pressure than Taiwan factory made.

Damn major props!!!! this this is bad ass!!! i want to do a sc setup now!!!!!!
I WOULD LIKE MOR VIDS THO :) which im sure are to come.....
 
So I have a few questions about this. Obvious since it's a bolt on supercharger, do I have to get the specific brackets to make it fit on the FS-DE or is there somewhere it can already mount to? Also, is the belt to drive all of this easily available or is it a special order type deal?

Basically if I'm thinking of this right, you just need the supercharger which is driven by the belts, intake, header (optional) and a wideband with an SAFC. Is there something I'm missing? Why is the intake way down by the supercharger? Is there an inlet/outlet on the supercharger itself?

Also, how much power do you think you're running? Would the 5psi be low enough to run on a stock motor without worrying too much about reliability over the long run? If it's making 150ish WHP then a good tune should keep it going for awhile.

Actually, when they installed the SC kit, they took out factory intake manifold and replace the one from SC kit. Also, we need to upgrade fuel injector (factory is 230c.c., the kit comes with 340 c.c.). Because you force more air coming, you need more fuel to gain more compresion. You also need another computer to rewrite "igition timing and fuel inject." For my case, when I first installed and dyno result was 194 HP, it's about 180 HP.
After that, I upgraded my exhaust system with high flow header, mid, muffler, carbon intake system, & DK clutch kit & re-program the computer for better performance. I guess it's around 200 HP now. Sorry for my bad English. Hope I describe it ok.
