Exclamation 2.5L & Supercharger: Factory?

The STX brings up and interesting question!

I was reading up on that particular vehicle in my Autoweek. I was suprised when I saw that Subaru had mated a Supercharger to the 2.5L engine! Yes, a factory effort to improve the 2.5L.

Of course, I want to my local Subaru dealership and confronted the people at Subaru. I told them I wanted one ordered if it came out, I have the same engine so it would only make sense! He quickly told me that the electronics and compression will be totally different and therefore I couldn't get it and have it under warranty.

What do you guys think? Have any of you asked the same questions? Did you get the same response?

Thanks,
John

It's pretty cool that your parts guy knew anything about the supercharger.

I think that it should be covered under a warranty. Since it is a subaru supercharger. If the dealership installed it, the warranty should be like Toyota and their TRD packages.

The dealerships around here don't know a thing about ideas. Just what is sitting in front of them.

Question

If Subaru puts it in anything from the factory, we can be guaranteed that several of our tuner companies will make them available and tell us how to install them.

I think you forgot one thing to consider. The clearance under the hood to get the eaton blower in. Rimmer couldn't get it to fit and you had to use a carbon fiber buble mounted to the hood to clear the pulley. The STX has a Legacy style hood. The RSK intercooler also sits up at a steeper angle then what you would get from Spearco. It would be nice if it fit but with an already cramped engine bay it isn't likely. I also doubt they changed the compression ratio. The STX would have more weight to lug around and need the torque from the higher compression. Of course this is just all talk since it isn't likely to ever be released as seen on the prototype. Kind of like the orignal SST (MY99-00) which became the current Eclipse. Man did they ever water that thing down!

Actually, Rimmer did manage to fit an Eaton Blower under the RS hood without the teardrop thing; it was labled the sidewinder kit because the blower sat on the side of the motor instead of on top. The STX does the same thing. You could easily adapt it to the RS engine.
The reason I don't think SOA would warrenty the engine if you put the same blower on is because I'm sure the engines are not identicle. Rimmer had huge problems with crushing pistons and fuel delivery (amongst other problems). It would only make sense that SOA would have lowered the compression and changed the fuel and timing maps for the STX. Our 2.5 is designed to run N/A; the STX 2.5 is designed to run with a blower. To me, at least, it makes sense that they wouldn't warrenty the RS engine if you mated the blower to it. The blower would be warrentied, but not the engine.

I went to visit Rimmer Superchargers today, and Rick was out of town, but I spoke with Brandon there who was was really nice. Brandon was finishing putting an Eaton blower on what appeared to be a Porche 944 (I could always be wrong).

Asked them why they aren't here on iClub more. Brandon said "with having to reply to 150 emails a day, put in orders and install parts, and do tech support - then if I spent time on iClub too, my girlfirend and dog will just walk out the door and I'll never see them again."

We discussed how I am the only person interested in a stage one SuperCharger (without InterCooler) to cut costs. At 6,000 feet above sea-level we could do 6psi without intercooler, but it would run almost 10 psi at sea-level and start to detonate quickly (it would increase to 9 psi by my calculations).

So, they don't want to make a stage one when it doesn't really save money in the long run. Makes sense. $2,695 is how much he would sell a 6 psi stage one to me, if I tap the oil pan for the oil return myself, and install it myself. Then I'd either have to buy an IC or a smaller pully and 1" shorter belt if I wanted to go to a lower altitude.

JC Sports lists their 6psi turbo with IC for $2,995 and it looks like you get to keep the stock cats for that.

I like the increase in torque with a SC, but don't like the variability in pressures with altitude changes. Decisions decisions...

Angry

They day I saw that the STx would have a supercharged 2.5 I fired off an email to SOA about how we should have this for our cars. I even made allusions to how TRD supplies S/C for several of there cars. The reply I got was that my comments would be forwarded to Product Planning. Sounds like the round file to me. Someone should knee-cap SOA's marketing department. I can hear their meetings now,"No americans don't want fast nimble cars, they want big fat SUV's and they really want underpowered compact cars. They'll never figure out that the other countries have the good stuff". Idiots.

Someone said something about hood clearance. It nothing like the Rimmer Kit.
The S/C is place where the powersteering pump would be and the power steering pump is moved. So the will be no hood clearance problems. Goto
http://www.subaru.com/calcon/gallery/index.html#
and look at the picture of the engine compartment and you shall see.
As for the warrenty, yes they may not cover the engine but if you were to lower the compression like they did on the STX enigne. I would say YES if you had them do the install and lowered the compression with new pistons.

Actully,the STx's supercharger was done by Specialized Vehicles, Inc. Troy, MI. Eaton builds the supercharger and the intercooler is from the B4.

It looks suspiciously like it has a completely redone intake manifold as well?
This could end up being so expensive to equip, it wouldn't be worth it.
