400 hp

i was curious what would be the cheapest most reliable way to reach 400+ hp on a supercharger? what brand of supercharger (KW,VT,CT,SOS) i guess would be the answer i am looking for or would turbocharger be easier and cheaper? im not going to skimp on parts but i want the best bang for the buck. BTW it is not my daily driver

I would say any of the superchargers with a tune ems injectors... your talking lot good amount of $$ I know someone locally that just got the new vortech you tune... its 3500 but then you need ems injectors and tune so your looking at 6k without install and im sure there are some more odds and ends you probably need clutch plus install for that.. so 7-8k probably

I did just did a turbo build for under $4,500 the trick is to go with a fmu.... you cant get as much power as with an ecu I made only 320whp on 7.5 psi but with that much hp this car still freaking flies.

is the SOS kit up gradable for more power? and also do SC have to POV sound turbo's do?

i think you should go about 340 HP. SC has a whining sound but gives u alot of low end power. turbo is way better but i rather buy a car that has factory turbo because the engine is built to handle boost. S2K NA engine is not good for turbo.

As much as people say the s2000 engine isn't good for boost I have never gone on this site or s2ki.com and seen a thread saying, blew my engine from too much boost. I run a turbo setup myself at 320whp and honestly if you run a setup with 350whp you will have more hp than you will know what to do with, you will smoke just about anything except for corvettes and anything faster. At 320 I beat a new m3 from a highway pull....

i used to own an ls1 f-body, 1997 CAMARO SS, its good for straight line acceleration. i didn't really like it, too bulky. i love the s2000 by the way keep it it around 320hp.

I recently read a magazine maybe a week ago. They test 5 different FI s2000's and with lots of info. The SOS was the 1 that produced the most power both in HP and TQ. It was also rated the best overall for price, reliability etc. 4 sum reason the Vortech was the least popular even though IMO i think it is the MOST popular out of people who ever did put FI into the S2000. The 5 FI kits had a various amount of HP from around 305 all the way to 390 (SOS) but yet the track speed that they listed was not too far apart. I wud go with the the cheapest yet most reliable..Vortech IMO

That test was so flawed it wasnt even funny. The sos kit won the test but also ran by far the most boost.

cause when they blew their engine, they're too embarrased to post it. would u post if you blew your engine reving it very high with turbo and miss shifted?

Question stuck like chuck!

Personally I'm stuck between getting a supercharger or itb's. I think 320 hp would be sick with the sc but the throttle response and low end gains of the itb's along with that sick roar of an intake sounds like it might be a more plausible setup.
Plus I would like to see how drifting would be with the itb's. Any suggestion?

Forget ITB's spend as much as a used S/C and get 1/4 of the power and you will be tuning it all the time not worth it most will agree

I would agree if I was looking for raw power but if you had read my post thoroughly you would see otherwise. But hey, no worries!

Maybe sombody else has some input! Prefferably sombody with itb experience. Thanks in advance for any input!

The Vortech SC i have has a bypass valve, which makes a wistle sound everytime i shift.

drifting would be no different than stock

aka, no torque down low.

Now that's the answer i was looking for! Can anybody show some dyno sheets for a vortech sc?

imagine that right there above, but with more peak hp and torque

centri blowers dont make power <5,000rpm

if you want a drift friendly setup you're looking at a smaller turbo setup or a static x motorsports roots blower

Question

Maybe my vision is off. Am I seeing a little bit more low end tq gains with the sc setup you've shown?

that one has much more than just the blower kit though, head work, valve job, diff pistons and custom cams.

frmo most that ive seen, it'll have a little more torque ~4000-5000 but not THAT noticeable

... I did read your post thoroughly... ITBs will hardly get you any hp gains as T's graph shows $1500 at the low end going to get you 10hp??? Totally worth it

From what I've seen as to how people respond to 10hp gain.......it seems to be worth it. People have said that a 10hp gain is very noticable!
Hey thanks to you and turbo six for all of your input. I have 10 months in Iraq to think about which way I wanna go but I'll keep you guys posted when I make a decision. Since I already have tien's drift suspension I might just stay that way. I'm a big fan of gymkhana but I also like the drivability of a more flexible suspension. So after I decide over itb's or sc we'll see where I go from there!

I gotta chime in here. I know a ton for pple talk crap about the greddy kit but damn gents just look at the TQ curve that can be had for 4k Everything included other then oil and plugs (even thou I would wideband and boost gauge the lil sucker)

Greddy is really not a bad kit if your fine with around 300hp its just that it dosen't have the chance to go much higher than that where as a lot of other turbos skys the limit lol.

Katoic personally I have met and spoken to someone with ITBs he admitted he noticed almost nothing and even the throttle response was not that much of a difference, Its your $$ though and your car but I would look more into them before purchasing

I would go for the SC. Man, I would love my car even more if it has 320hp under the hood. I floored it everytime I merge on an interstate. After a while, it doesn't wow me anymore. MORE POWER IS BETTER ON THIS CAR!

on S2ki isn't there a dude running the kit getting about 350 out of it. and the real big plus to the kit is full boost at 3500rpms. this kit is a jewel

Taking this into consideration......but only consideration being the fact I haven't seen the difference in the power curve between vortech or comptech sc'ers etc. maybe if I could find the differences that would help me decide. However search engines suck.........or maybe I suck at thinking of the right keywords! lol

I have a greddy kit with arp head studs and aem ems, and I tuned in at 357.7 whp on a dyno dynamics dynometer which reads 15-20 percent lower than dynojet machines putting it at 405ish on a dynojet machine. It's running 14 psi on high boost, and 10psi (making 318 on that machine or 370ish on a dynojet)... The car absolutely screams, and with such a small turbo (18g) it spools up nicely. With that much power with a sc you would never get traction...

just my 2 cents..

here's the dyno sheets:

Oh and to my understanding centrifugal sc are top **** according to how they work. As for those mentioning anything about turbo charging, that is out of the question. I don't have the money for a big enough turbo to make up for the boost lag.
I've driven many cars with tc'ers and having to biuld boost seems like a waste of time when you can only run certain tc'ers on 15-18 psi, the affordable ones for me that is!

is that a synchronic bov that I see?
Well as far as never gaining traction........that wouldn't be to bad since gymkhana is about controlling your car with no traction. That might be a plus for me.

So this thread is amusing to say the least. Good job beating that highest greddy hp by alot. That turbo is not even close to capable of 405 whp look at the compressor maps they tell the story. I have no idea how anyone could get 350 out of it.
