I chose an HKS kit for many different reasons. And I love it! you have to think what you want...

I wanted a mechanical kit... Meaning no after-cooler I wanted an intercooler.. I also wanted a kit that had its own cooling.. That interfered with the motor as little as possible.. with no electrical work. I make 411 hp on a mustang dyno on 15psi and 93 octane.

 

look awsome

Why would you go with a supercharger?

 

If you seriously ask such a question, that just means that you dont have enough knowledge on how thing works in real life or how people can have different ambitions.

I owned two turbosetups on my S. One was a gtx3071r with pfab elt and all of the gimmicks and nice stuff. Power was great but the car was so laggy! Even with the ultra quick spooling setup! The turbo you mentioned is even more laggy! Which is only usable on the highway or some pulls on the street. On the track or the canyons it definitly not as good as a sc setup. Its going to be a whole different car to drive with a turbo kit. I hated it after a while how the power was so badly usable compared to the smoothness of the oem setup. But im not a teenage boy who only thinks about beating as much other cars in a straight line as much a possible. I want to have oem charisteristics and just a tad more juice. So SC is PERFECT.

And then there is reliability.. I cant even mention enough how big of a factor that is for alot of people. My car caught 2-3 times almost on fire because of the immense heat and all the lines just cracking and tearing. It was a running time bomb for faillure. Even when i switched to hardlines i still got alot of troubles. I had to check everything each drive. And IF something goes wrong, it goes wrong in a BAD BAD BAD way. Oil and water is connected on the engine.

No, my next setup will be supercharged. Just have the oem engine charisteristics and RELIABILITY. No heat or praying to god that everything will stay in one piece. Never ever going that route again. And will not advice people to go turbo unless they have a second s to drive and a bulky bank account.

I do however had lots of fun with the turbo setups and you can get ridiculous amount of power. Be be honest here. Its not an s2000 or a track car anymore. Its a different beast. A whole other level And THAT will NOT suit everyone.

You should know better before saying such a ridiculous thing.

 

It's funny that you chose the old Comptech SC with the smallest pulley for comparison with this turbo. An SOS 2 with the smallest pulley would be over 500rwhp.

Reasons I went with a sc:
1.) No time to tinker with or fix things on a weekly basis
2.) Wanted to be able to take the car on 2,000 mile trips without breaking something or worrying about it
3.) Wanted the car to sound similar to stock
4.) Bought the car because of the motor and its high revving linear power curve so I wanted to definitely keep that
5.) Wanted a kit that is basically a drop in and didn't need me to relocated, reroute, drill, or modify anything
6.) I wanted to be able to control and predict what the car does on the track, dragon, and auto x instead of being 500 HP and losing to stock s2ks and civics except for the straightaways
7.) Did I also mention I didn't want to be one of those guys who's cars always in the shop?

I'm curious why someone would go turbo unless it's for a very specific application. Seems like you give up a lot to go that route. If I just wanted power, I would buy something else and turbo that to 1,000 HP and call it a day.

BTW profit_child, I've never seen a dyno for the his kit making that kind of power on a mustang dyno. Can you post yours?

So let's step back a second here, you portend that a supercharger setup that is mechanically driven is somehow more reliable than an exhaust driven setup? You then went a PFAB manifold which uses garbage 304L, you probably didn't coat your hotside or manifold, because then PFAB would void your warranty and had it absolutely pouring heat into your engine bay, you have to relocate all sorts of stuff to make it work. I'm guessing you picked a larger hotside than you needed and since it was a single scroll ELT it felt like laggy garbage but you had great peak power right?

I can't blame you for having a bad feeling with turbos with the setups that you chose to go with. You probably did research on the forum and went with what you thought was good. You didn't coat your hotside or manifold which does a great deal to reduce in bay heat, and even if you did, PFAB would void your warranty. You went with an open single scroll T3/T4 frame turbine housing which is notorious for poor spool characteristics, and probably went with a significantly larger hotside than you really needed to since that's what the internet experts probably told you. The fact of the matter is, OEM's spend hundreds if not thousands of hours designing their FI kits which are always covered with heat shields and typically run very small turbos which taper off at the top end of the RPM band. I know that with your kit, you had to relocate literally everything which right off the bat is a huge pain, difficult to get right the first time, and of course vastly raises complexity.

These SOS kits literally bolt right on, without relocating anything. They're cerakoted from the getgo and don't dump heat into the engine bay which is a huge bonus and makes use of the factory heat shield to not melt everything. The biggest advantage and disadvantage to their kit is the hotside they chose for that turbo, the Mitsubishi .94AR twinscroll housing.
The housing sucks for top end, but the trade off is that it spools about a thousand to 800rpm earlier than a t4 twinscroll, and even more for a t3/t4 open.

The last part is drivability. I've driven plenty of supercharged S2000s, and they don't really have great amounts of power since the only bit of power they make is at the tip top of the RPM band. It doesn't matter if you're comparing that GTX3582 kit there vs the 500hp supercharger guys, the turbo kit makes more power everywhere and doesn't really have lag. All forced induction systems have their pros and cons, and comparing a poorly put together turbo to a good supercharger isn't fair.

Supercharger setups are fun I guess, but a properly built small turbo s2000 will be my pick every day. An EFR 7163 on this car with a properly designed manifold would be an absolute blast.

1) So do it right the first time
2) See above, my sister's RDX has 90k miles on it without issue and the new civics will be turbo, so there's your Honda example.
3) So adding a supercharger doesn't make it louder?
4) Turbine and turbo selection. Also, linear power curve? Like that characteristic dip at 4-5k?
5) SOS kit does that, with the tradeoff of lack of topend compared to other companies kits with the same turbo
6) Foot control and boost control. Ever hear of boost per gear? How about a boost controller? You can control your power with a switch. All the fastest S2000s are supercharged right?
7) SO DO IT RIGHT THE FIRST TIME! Don't settle for half ass designed kits with poorly matched turbos, or huge ones that put you way way past your power goals. Somehow almost every manufacturer in the world can figure out how to get this right.


In summary;

Superchargers are easy because they don't make as much power. The issues that you guys gloss over like belt slip, horrible IAT's due to poor AWIC implementations, kit quality (KW), and so on because you had bad experience with poorly setup turbo cars shows. Any idiot can bolt a turbo to a car, just like any idiot can bolt a supercharger to a car. The difference is a poorly done supercharger setup will just make less peak horsepower, have belt issues, etc. A poorly done turbo is a far more variable bucket of fun.

 

Why are you even posting in here? OP was asking about what sc to get. This is not a sc vs turbo debate.

 

Power isn't everything when there's turns involved. Driver skill and proper car setup matters. Just get kit that can make a little over 400whp (not HKS) and focus on other things like brakes, oil cooling, tires, aero, etc.

 

OK, comptech or sos supercharger kit is my pick.

I never said skill and a properly set up car doesn't matter, just that the turbo setup is faster.
