Angry Can the 4 guys who own a S/C please post a review!

Im seriouly considering the s/c. Perhaps even a custom job. I talked to Rallispec about maybe a Powerdyne s/c set up. They are up to doing it, but unfortunately my wallet isnt at the moment. Since it hasnt been done before, customizing new brackets and intake plumbing stuff can get costly (not to mention my good ol' 99MY maf issue).

So I've heard mostly the bad stuff with Rimmer. Does anyone have good info to report? My main concern is the reliability thing. 8lbs of boost (or more ) with no headaches would be great! Does the new autorouter come through with its promise or shall I give up my s/c dream!?

I concur captain! I'm interested in a custom kit myself (MY99 Legacy GT DOHC). I know that giulio is interested in scraping a s/c kit too for his dohc MY98.

I hate to do this, and stir up an beaten debate, but with turbois clearly being the more popular route, and an ample supply/variation of kits available, why not jsut go that route?

Some of us just like the properties of the supercharger better. Not to mention its less invasive, and I get to keep my Cruise.

adam99rs...
Why didnt you buy a Honda? Why not put a turbo on it and make it as fast as your RS? Parts and upgrades are cheap and easier to find?

I think everyone who owns an RS can appreciate its uniqueness. Obviously there advantages and disadvantages to every system. There is technology to make a great s/c system for our car or any car, its a matter of developing it, if you want to(which is subjective).

I hope good tuners like Cobb and Rallispec can develope a variety of kits for us enthusists that will provide us with performance options. Weither its a: N/A, turbo, s/c or NOS kit... Competition is a good thing.

Rich, I hope you realize that Adam is the owner of one of the fastest Imps in the country - he does have a good idea of what he's talking about. A 12.69 quarter mile goes a long way. Oh, and he does own a Honda - a very nice S2000. So believe me, Adam appreciates the uniqueness of his RS.

The whole supercharger thing has been beaten to death - and the RS's uniqueness is also it's downfall. If you do a search on superchargers, you'll find that Jackson Racing has NO interest in doing one for the RS. You'll also find that people have had no end of problems with Rimmer. TRI Tuning reportedly has a supercharger that they're researching, but that's about all I can think of.

Good luck if you're planning on doing a custom kit - I'd be very interested to hear about it. I'm going forced induction myself, but will probably be putting a turbo in, using the Vishnu system. An 8 lb supercharger would be an interesting alternative.

Basil,

I certainly understand who Adam is! I like the fact he has contributed to developing our cars. In effect, he has helped us all. But I was trying to make a point about options available. (and I forgot about the s2000 he owns ... but I was thinking civic)

As far as the s/c issue being dead, well I disagree. As long as we have tuners like Cobb and Rallispec, you never know what can pop up! If Rallispec can do a custom job for me... well, that certainly can be good for you... and everyone else. The more options/competition, the better. The title of the post clearly states that I was simply asking for the s/c guys to speak up for a review. Not state some type of turbo/sc debate.

It is a shame that the sc/turbo argument always seems to pop up, I think it limits discussion from the minority (sc owners). I think we can all benefit from discusion.

The Vishnu system is probably the best kit out there now! But it took mistake by others to get a kit that is improved. I just hope other tuners with pick up where Rimmer left off and build a better mousetrap. Good Luck with you mods.

Just to add fuel to the fire, I am currently pondering the option of forking out a *LARGE* sum of money to have my lowly little FWD 1.8L transcended into a 450HP firebreathing, Porsche mauling beast. This conversion includes EVERYTHING, and I mean EVERYTHING, from Leeda remote reservoir struts, 450HP capable tranny, closed deck EJ25 with forged/billet everything, CARB legal turbo or SC, mongo brakes at all 4 corners, and a whole host of other things.

Rally Knight is already in process to get the kits their own CARB EO numbers, and I have a couple of months lead from the time I say "do it", to actually getting the car back. They can deliver 450HP in either supercharged or turbocharged form, on 92 octane gas. This, of course, assumes some heavily strengthened engine internals and transmission gears, which they also make. Knight Steel, the corporate sponsor of the Rally Knight team, is a steel goods manufacturer, and gears are made of steel, after all.

yep. I talked to JR the other day. He said they're in process, and they have to put 5K miles on teh kitted cars for testing purposes as part of the certification process.

I plan on taking another trip up to the shop in Upland to have a looksee at Rally Knight's street car with the prototype for the 2.2L. Rally Knight will be offering CARB legal SC and turbo for the 2.2L and 2.5L engines.

So, basically, at the end of the process, my car will cost about the same as a lightly modded new RS, but will have MUCH better performance in all areas, braking, acceleration, handling, etc. The only limit will be the loose nut behind the wheel!

I'll let you know when I arrange a trip up there. You can see things firsthand.

I certainly appreciate your desire to stand out from the crowd, and I agree that options are a good thing. But trust me, being the ginnea pig ain't all its cracked to be!

y only point was that with the variety of turbo kits out there, and the turbo Imp itself coming to the states, it appears that is the route go (charactersitcs of the EJ25 motor aside - since with good power as an NA car down low I just see a SC being he best "mate" for this motor).

But, I agree that what it takes is someone taking the time to improve upon Rimmer's initial concept. Keep us posted....I'd love to see a SC Imp that can hang with the turbo guys.

And thanks for the kind words on my little Honda too......I'm not a Honda fan in general but the S is something special.

Kev - I picked up the Piper X for mine from Andy/Dave/Jorge when I was last there getting my exhaust done......bolted right on. Basically, you can do whichever filter you wish, provided you have a MAF adapter plate. I had a K&N around here too with an adapter plate that I used to run....I'll look for it and if I find it, you can have it.

I hear what you mean about the GReddy. Thing is, it's so car-dependant. GRedyy's are used extensively in Japan, on a variety of care, as well as here in the states. But I don't think they "mate" well to the Subaru MAF's (at least the 99 "bad batch")....You have had your awhile, so I think it served you well.

Adam, out of curiousity, how much have you spent on modifications to date?

Rally Knight was quoting somewhere in the $20K region to completely do the drivetrain, suspension, brakes, etcetera. I know that STi V-anything can't be cheap, and you had a nice setup prior to this.

PS, I forgot, I'm not going to be a guineau pig exactly. They've already built a couple of test bed cars, and the owner drives another proto as a daily driver. I would most likely have one of the first run production kits.

I never took the time to add it up to be honest. I think to date, I probably spent a bit more on the car as the car cost me in the first place, though that was over 2 years (I got my MY99 on 10/20/98). The car was very nice bfore...everything I wanted in fact; I just felt it was time for a change. Having driven a V5 in Tokyo last yeat, I was hooked on it, so upon my return, I started looking for one of my own.

Keep us posted on the Rallyknight thing.....though $20k is a lot of money, for all the work they are doing, its seemingly fair.

See that thing in front of the ABS on my turbo RS? That is my fully functional cruise control, simply by (1) rerouting the CC cable across the front of the engine bay, (2) extending the vacuum line and the wiring harness, (3) and making a bracket and re-using a bracket that previously held the right side of the airbox.

We did this during the JC Sports group buy turbo kit install.

You can keep your cruise control with a turbo - that is the least of your worries.

You don't hear much good about the Rimmer supercharger because there isn't anything good to tell. On planet Earth, there are approximately 4 Rimmer supercharger kits and each of those only work (and this is a somewhat relative term) due to the great efforts of their owners who basically rebuilt the kits themselves. As of yet there still is not any MY2000 or MY2001 Subaru with a Rimmer supercharger kit.

You can ask the question a thousand times, but that won't change the answer.

Rich L - Oh, I agree.. Believe me, if Rallispec cooks up a s/c kit, it'd be a dead heat.. I have to say I admire you for having the guts to pony up the cash for a custom system - I don't have it in me to be a ginua pig (I apparently can't even spell it..)..

ARG - maybe you could make a few bucks as a side line job by installing working versions of the Rimmer kit ? ;-)

Rich - with proper engine management, my Rimmer setup (7psi autorotor) would be very nice ... the nicest thing for me is that the car feels like it has a much bigger engine, it doesn't feel like a 'turbo' car ... ok, I never drove a turbo car ! ;-) (just trying to describe the feeling, PLEASE no wars guys) It tends to have a hp/torque curve similar to stock : good low end torque, doesn't pull as much above 5000rpms (2.5" catback exhaust already helped a bit, I'll see w. the whole 2.5" line & custom headers)
There's no power spike, but boost kicks in very fast still. Max boost available at 2000rpm. here's what you can expect out of it :
I floored it in 2nd at 2000rpm, my friend w. my ex '97 SVT Mustang Cobra behind me; he floored it (well not really, that's impossible in 1st gear ! ;-), at first I gained a few feet on him (AWD baby), after, he very slowly gained a few feet back (we stopped at around 60mph). I'm sure at higher speeds he would beat me.
If you want more, to eat C5s & 911, get a turbo.

On another note, we are still Guinea Pigs as far S/C kits go, I came close a few times to just put a rag in the gas tank & blow up the damn car, that's how pee'ed off I got sometimes. So now you know what you would be getting yourself into, good times, bad times ...
AND you will need a new fuel pump, adj FPR, stronger clutch, exhaust probably.

There's no instructions w. the kit.
I have been having probs w. the car. It runs fine for a few weeks, then CE light, bad hesitation @ 4000rpm (@ steady speed), bogs at low rpm when cold, idle not stable. Then 'presto', no more CE light, all the above probs go away !! ??
One prob that's constant with colder weather: difficult to start, needs 2-3 tries.
Also, the belt tends to slip above 5000rpms (we re-tighten the belt, it holds for awhile, then starts sliping again & so on, & so on)

Wow, that's my longest post yet !
[edited about 4 times too !]
Hope it helps
Phil

Some of us just prefer a SC to a turbo. Yeah, the turbo is faster in the top end, but - like Kwez said - with an SC it just feels like it has a bigger engine. It's a life-style choice. I prefer RWD-or-AWD sports cars to FWD sports cars and I prefer SC'd engines to turbo'd engines. To each his own.

My personal plan (if I can ever throw together the cash) is to put a Vishnu TEC-II kit and a Rimmer 2nd gen sidewinder kit on my car. From past discussion I believe that should settle the engine management issues present on the current Rimmer kit and come in at about the same cost as (discounting labor, which I'll probably provide myself) as the Vishnu turbo.

Of course, there are two closely competing alternatives that I'm also considering. One is just jumping on the merry bandwagon and getting the complete Vishnu turbo kit (it is a very well done complete solution) the other is trading my RS in for a WRX when they come out. However, both of those leave a bad taste in my mouth. What I really want is a reliable SC on my current car.

Rich L,

If you're like me, you might consider the TEC-II and an SC. I can't do it personally right now, but I think the TEC-II would solve all of the (technical) problems with the Rimmer kit. I can't say the same for delivery, but ARG has posted Brandon Granthem's (sp?) contact info some time back, so you could deal with him directly on the SC kit.

Just my $0.02,

-Red

Thumbs up

Finally!

It took 18 posts before someone gave me a review! (thankyou Kwez!)

Man I feel your pain, but torching your car? Thats pretty bad! I guess when the s/c is working right its worth it.

Red-Impreza, I agree with you. Until there a new kit to shout about, I guess will need the TEC-II to fix the bugs. $$$$$$

personally Im not to crazy about the idea of water injection, I wonder if the TEC II can allow for a high boost setup!

Better yet... how bout a twin s/c set up!!!

Come on Tuners!

Um, just to add a bit more noise, I think Rally Knight making 450hp and being CARB certified is BS. Even making 300hp and being CARB legal would take a miracle. According to a post by Shiv a couple days ago, a CARB certified system can NOT change the stock ECU. I believe he mentioned that in response to someone who was hoping that the 2.5TT project (AMR I think?) would be CARB certified. AMR is (last I heard) replacing the stock ECU with a "pretuned" aftermarket chip. I don't know how anyone could hope to make more than 210/220hp or so reliable HP without working the computer over to keep the engine from melting, panicking seeing the boost, exploding, etc... and still have decent emissions. I have nothing against Rally Knight and I haven't seen them make that CARB or 450hp claim yet but I don't want people's expectations to get unreasonably high. Of course I've only heard about this in Shiv's post so I could be wrong (god forbid).

Kwez brought up one of the facts about the S/C that has really deterred me seriously considering any that are out on the market. The fact they run on a smooth pulley, on the back side of the belt, is very discouraging to me. I had a S/C on my 97 camaro RS, yes another RS except this was a V6. And I had the same problems with slippage. It just isn't worth it. You lose considerable boost at high rpms. And if you don't tighten it properly the first time, forget about it, most likely you will glaze the belt, rendering it useless. I don't think this setup is that bad to replace a belt, but on my old kit, I had to remove the compressor in order to change it. They'll eventually produce a good one, the market would be there I think. But I played with a S/C long enough...its turbo time!
