for the supercharged fc's out there..
 

I have an 88 n/a, full RB exhuast (headers back) and a full custom CAI. Now my question is, when it comes to slapping on a supercharger what is the next best step after the exhuast and CAI. I dont want to have to go thru the troubles of upgrading for a turbo. I'm not a wiz when it comes to these engines thats why I'm asking. Porting, ECU? let me know, thanks.

Turbo setups are easier and more effective bigtime, i'm turboing my 88 too

I second that

why is it more effective? i was thinking about supercharging my 86 and i think it would cost more to change over to a turbo'd. i was just curious about the differences

i didnt even know there was a sc for the fc's

i just googled it, sorry for the wasted space, shoot teh noob


how much power you think the kit pulls

well the super charger has more limits and to get decent power you would have to get the carb set up because the FI sc is expensive and dosent make shit for power. i would go turbo, plus i heard the sc's have a lot of defects(not sure if its ture, i think it was only one brand did.)

i wish i had a bolt on turbo kit :wallbash: that would be awsome, i would kill so many of those ricer bastards :pokeowned

I did a little number crunching a while ago and found an Eaton M90 S/C will provide around 260 rwhp, assuming an IAT of about 130*F which means intercooling and possibly water injection are necessary.

This would also be on a standalone, however you may be able to pull it off with an safc or similar, just expect about 20 rwhp less.

Assuming electronics are taken care of, it should cost around $800.
The secondary injectors being around $150, S/C should be less than $150, and intercooler and piping< $250, misc. brackets, feed piping, and other such items would take the remainder of the money. This setup will have basically no lag whatsoever.

Now comparing this to a turbo setup, a cheap manifold is $175, internally gated H1E holset turbo is around $400, IC with pipng $250, BOV $20 for a stock DSM one, injectors $150, a turbo adapter is around $80, oil lines $100, other misc items $200. Thats about $1400 for a turbo setup. This setup is good for around 350-400 though it will have appreciable lag.

where can you find a supercharger for 800.00?

All the ones I've seen for FC's are useless pretty much. 3k for a supercharger, when you can buy a jspec TII and rebuild it for less than that.

i have to agree with these guys.I was originally gonna go the sc/na route,but if you crunch the numbers,youget way more bang from the buck by going turbo.My whole swap to t2 cost 3k,including a haltech and drivetrain changes,i am now making about 350whp,whereas a supercharger alone wil probably cost close to that by the time you get it working and will only get you to maybe 250.

yeah but the cool factor overrides the rest... if u are looking for something with WOW like me a SC is in the books

When you can find a super charger for $150...let everyone know lol. Go turbo, its got alot more possibilites, and really isnt that expensive. A guy is selling a FULL gt35r turbo kit for $1500 right now...thats a deal.

Neither adding a turbocharger or supercharger to the NA FC is a matter of "slapping it on". A search on "supercharger" will turn up plenty of project threads. I think one or two was actually completed.

Aaron Cake is right, each project requires making modifications to the car that it was never designed to operate with. Tons of people ask these questions and I'm willing to bet the percentage of the people that actually ask and complete or even start, doesn't even make double digits.

Not to say it's impossible, its quite possible, although it requires research and mechanical ability to make it work.

Consider yourself lucky though, you have a forum that has tons of FREE information on virtually every aspect of your car, and people that would be willing to lend their advice for free, that is one hell of a resource.

One of the baddest FC's on an Autocross I've seen was a SC FC. It pulled like no ones business. The owner has never taken it to the dragstrip, but I'm guessing it's nothing that impressive. Low 13's maybe hihgh 12's. NO serious top end. I've never seen an FC pull out of a corner that hard.

It had a 9" roots blower, and some good porting.

camden SC bolts right on

there was a guy on here about a month ago selling a SC kit for 750.00

http://cgi.ebay.com/ebaymotors/98-05...QQcmdZViewItem

I have one sitting in my storage that I got for $150 with a short snout, and 6 360 cc injectors w/ clips.

A little while ago I found a Millenia s supercharger for $100 shipped on eBay.

You aren't going to find the cheapest way to do anything in a kit, you have to piece it together. For example, a rebuild kit costs around $800, but you can piece it together for around $500.

One example of a completed supercharger project is Zbrown. While it was a fairly slapped together setup, it produced decent results for the money invested.

spch's are a waste of time and money, you could get a turbo motor with that kind of money.plus you can leave your na tranny in with the turbo motor, unless you want more power..then change the drive train

You can find an M90 for next to nothing. go to Clubgp.com and you can find them all over th eplace from GTP guys going turbo or upgrading to the gen V M90.

Where do you com up with your info? If you can make power on a carb setup then you can make just as much power, with better driveability, with an standalone setup.


BC

honestly if I did a supercharger I would do a Centrifigul not a roots!

Why? If anything, a screw is the best. A roots is only efficient below about 8 psi, then a screw is more efficient. A cent. type has most of the lag of a turbo, without having the benefits of easily increased boost.

try finding that guy that was selling his for 750 SHIPPED!! that was a awesome deal. if he still has it.. ill buy it. :) id recommend trying to find that though to see if he has it still.. thatt was a killer deal.. its a kit made for a FC and included everything to bolt it up..

It was sold.


BC

ooh.. that was a awesome deal on that supercharger.. im surprised it to so long to sell..

Basically, to sum up previous posts, there is one good kit made by camden, and it is very expensive. You can do a complete turbo swap for a good bit less money and have way more room for growth. The people pricing out the setups using a custom setup forgot to mention that there is a whole lot of custom fabrication that goes into getting them to work. As Aaron said, nearly all of these projects end up abandoned.

Well you have to keep inmind of a few things:

Your gonna have to do some work either way (if you go turbo or SC). On an NA once you add boost you still have to do the supporting mods. The only difference is HOW to boost is achieved. You still have to have the mods to support that boost. Keep that inmind.

Both superchargers and turbos both have their own pro's and con's. In a nutshell, SC's have a linear powerband for boost (as RPM's increase so does boost, and it also comes on at a earlier RPM). However they are not as common on a FC, maybe a bitch to get support or parts. Turbo's dont exactly have a linear powerband for boost, there are WAY more turbo fcs so support and parts you can find easily, and IMO theres more options with a turbo since we can choose from a bigger variety of turbos, twin setup, singe, sequential (however unlikey it is).

Is there any particular reason for going SC rather then Turbo? If your just looking for more power i would recommend going turbo just because of the support, availibility of parts, the options you have and all that.

I understand alot of people want to be different and hence they want to do something out of the box sorta speak, however, just make sure your not getting in over your head sorta speak.

thanks for the feedback

A centrifugal blower will have more lag than a normal supercharger, but about |---| much. It is of course dependent on the engine RPM, but that's how superchargers work.

Let it load in the background then fast forward to 2:33, where the real action begins. Watch the boost gauge, as soon as he steps on it, the gauge goes from vacuum to 10 psi of boost, then up to 20 as the RPM increases.

And procharger's website... http://www.procharger.com/

I haven't researched Paxton or Vortech super chargers, so I don't know if they have problems. I did however watch a old muscle car with a Vortech S/C get dynoed. It was like standing in an earthquake. :D

Yeah, I know my buddy has a vortech'd 01 GT, it's lag isn't near a turbo, but not as instant as a roots/screw.

Well the CSC has the added benefit of an intercooler but does lose some response with the IC and piping. Roots / Screw blowers typically replace your intake manifold and bolt directly (or close) to the block. However they're not as efficient running a low RPM, and they have more parasitic load.

I remember a show that had the Merc SLK, or some similar car, with a SC which they said took 100 hp just to run.

CSC = Belt driven, geared, turbocharger. It has the efficiency and high power capability of a turbo, without the lag. The downsides are cost, and lack of a bolt on kit.

i was talking about sc's that where made for the fc.

The reason you get the supercharger is not price, its for instant boost that is suitable for autocrossing. In the long run, to get big power out of them costs more money (as everyone has pointed out) then a turbo. I am actually taking a TII motor and putting the supercharger on it. That way, in the future, if I want to have a supercharged turbo motor, its possible.

The other reason you get a supercharger is to be different. That in and of itself is a double edge sword. You are different, that's great, but the parts out there for it, along with the experience with them are limited.

I wanted to be different, and I like the whine from the blower.
