twincharged s2000
i have a s2000 and im planning on going turbo as soon as the full-race kit comes out.
anyways, i was looking at some comptech supercharged s2000s and i noticed that there *might* be enough room left by the supercharger for an additional turbo kit.
what do you guys think? yes, i do have money to waste on this. of course, if i do this, ill need to build my f20 with sleeves and all the other goodies.

Re: twincharged s2000 (slitfill)
Not worth the time nor money. Meguirs had a sponsered Integra a few years back with both and it dynoed out at like 4XX horsepower and 3XX something in torque. That was also on a heavily built motor. You would see just as good if not better numbers with a either a supercharger or large single turbo and at half the cost.

Re: twincharged s2000 (slitfill)
the point of the twincharge mr2 was to retain torque down low with the ROOTS blower that it had stock and to make insaine top end with a turbo.
if the 1.6 made torque down low without the stock blower, they wouldnt have twincharged it.
the purpose of twincharge systems is to retain instantaneous throttle response (aided by a blower) and very high RPM power output.
thats the only purpose to having a twincharge system.
and i beleive the supercharger kit u guys are refering to is a centrfugal blower which needs engine revolutions in order to make boost, so it needs revs to be responsive.
imho it would be pointless, unless someone used a roots blower or spun a centrifugal blower fast enough at low rpms ENGINE rpms to make boost then disengaged it when turbo boost kicks on! (in order to eliminate the blowers parasitic effects)
but im not sure if centrifuagl blowers take the same amount of power to turn as roots blowers so that step might not be nessessary.
anyways, just use a BB turbo. lol. no blower!

why not try a really small turbo for the low end torque and a supercharger for the top end, while you're at it throw in some itb's.

after some research, the comptech supercharger is somewhat like a turbo. supercharged horsepower and NA power stays the same until 3k rpm when the supercharger begins building boost.
a turbo kit starts to build boost at about the same rpm. it will give more power compared to the supercharger because of its non parasitic properties unlike a SC.
anyways, the comptech unit will not help low end because of its turbo like "spooling" properties. however, with 2 units providing air into the engine, the turbo will reach full boost sooner.
unless a roots type sc is available, twincharging might not be as effective as i hoped it would be to provide low end power which will help spool the larger turbo.

Re: twincharged s2000 (slitfill)
read up on the subject. it is a good idea in therory but its bad in reality. i am not smart enough to explain it but they did a write up on it in turbo magazine, and the conclusion was bad juju.
something about how the air gets so hot after being compressed by the supercharger that by the time it goes through the turbo you have rediculously hot intake temp, and the air volume is high but not the air density. therefore no power. its like running a small turbo way beyond its efficiency rating. it can mover the air but it gets too hot.
i think thats how they exxplained it, only with more math.
also, making power isnt the problem. keeping the rear end and tranny from going to **** is the hard part. the only way that i could see the benifit of this is if you had someone that really knows what they are doing match a supercharger and turbo charger to your gears, head work wheels size etc. in order to achieve low end torque at x selected rpm level in order to accelerate out of a corner better.
all of this will still only be good if you plan on making a reasonably low amount of power. it sounds like you want a bunch of power, and probably not for dedicated track use.
really its not worth it. just get a good spooling turbo, and so forth, and you will be set

Re: twincharged s2000 (Mr.E.G.)
Anyone else find it funny that someone would pose a question like this...a forced induction setup that has been done by shops with TONS of experience, an already built engine platform for the setup to be placed on...and just did it so we could see the end result...
lol, just seems funny to me...a guy who im guessing has a stock S2000...who hasnt even started building the motor properly for a turbo kit...but is already wanting to discuss if he should do a dual induction style setup...hahah, and ends his post with this...

Truthfully...you should have already done this if you're considering doing a turbo/supercharger setup on your motor. Which is why this conversation is kind of pointless...

^^ agree. And if you have money to WASTE on a project like this, I'm sure you can AFFORD a 360 Modena, GT3(2), or at least an M3. All of which I'd rather have than the S2k. (except maybe the M3, unless it was a CSL 
)
