I think that isn't ok, it will take some water & dirt, so much turbo lag, more negative than positive...

Thats dumb ... i think

Actually, STS has a patent on their oiling system. Check this out:

I remember the rule of thumb is 8:1 for blowers. I can't imagine he amount of octane boost one would need to run for 11:1 to prevent detonation / pre-ignition, if it'd even run correctly on 91...(since the car already takes 91...)

I dunno, I guess I'm not THAT into power. This car will break loose with an automatic transmission up into 3rd gear...that's plenty of power. After that, it's a matter of getting it to the pavement and stay there...

Sure it will work. My car runs fine on 91. Low compression motors require higher manifold pressures and high compression motors require lower manifold pressures to achieve the same results.

Since the Z has a 7AT, how about breaking traction in 4th and 5th?;)

Why are people so afraid of the unconventional? Until you have had one/ridden in one or beat one then you really dont have any REAL reason to knock on it.

The filter doesnt absorb any more dirt than up front,

There is a water shield BUT if you are driving a boosted 370 in the rain you are just wrong anyways. All that money in a car and you cant afford a beater to drive in the rain? Come on.......

Turbo lag? please... gimme a break... There are so many new turbo's out there that can produce 600whp and spool crazy fast.... Just because there is distance in the pipe doesnt mean there is still not constant pressure in the exhaust pipe. If you call 500rpm over normal turbo lag then fine but to me and many others the ease of installation and no heat issues under the hood would be worth a 500rpm lag over a normal turbo......

Its a good system, generally technology gets better not worse. If it didnt work well then the concept would have failed a long time ago. I drove my friends Z that we fabbed up his rear mount in and it pulled way harder than my Voetech Z and I was using the 2.87 pulley.....

Different strokes for different folks.

If you want less turbo lag, just use either staged turbos or smaller turbos. I'd use staged turbos. Anyone heard anything on aftermarket twin-scroll turbos yet? That'd fix the turbo lag all-together.

Brazilbro 06-20-2009 04:06 PM

how about a supercharger under the hood and a turbo in the back!:yum:

Crash 06-20-2009 04:08 PM

I would say twin charging these cars isn't all that bright. LOL You'd need to fully build the motor to handle that. A good supercharger will feed all the air the stock motor can handle in the first place.

I never really looked into the STS setup because it just seemd like a joke. But, when I started reading independant reviews, it looks like the system really does work and there's no lag.

Check out the youtube video from 2 guys garage:

Or on this one, you can watch the boost build on the pillar mounted boost guage:

Wow... Being that I'm buying my Z06 Monday (I think) that just got my mouth watering... I was just going to stick with a super charger... but the STS looks great. Glad they did eventually put an intercooler on the kit.

gorillanismo 06-22-2009 09:34 PM

thanks for the video phimosis, I really thought that system will never works great!!! but it works awesome!!! hehehehe

I always believe that it will have turbo lag, water and dirt on intake and less efficient, but damn it sounds good!!!

Minicobra1 06-22-2009 09:46 PM

Looks like these guys have done a lot of cars, I haven't seen anything about any failures reported. I'm all for trying anything new, as long as the results are proven. it looks like it would be a little easier to convert back to stock when it came time to doing a smog check. :tup:

On the corvette, the filters are out of the way of water and dirt. The original design had them sitting almost directly off the turbos. But STS later redesigned them to put the filters up high.

Turbo-lag won't be an issue. Simple physics: Take a 1 foot straw, pinch or block one end of it and blow through the other. Then do the same with a 3 foot straw. The result will be the same. You'll have no leeway to push any more air into either straws no matter their length. The only variable factor is the elasticity of the material the straw is made out of.

In the case of a rear-mounted turbo, the lag isn't going to be that much different than a front mounted turbo kit. The big variable is the density of the exhaust air, not the density of the intake air. The exhaust air will cool very fast allowing the air to contract into a denser accumulation. However, the mass behind that air remains the same so the end result is almost no different than the front mounted turbo kit. In this case, we're trading time of travel for air density.

Intake air, however, is going to near identical to a front mounted turbo kit because when the car is on, the turbos are always spinning and air is always moving. The pressure in the intake piping is not constant, but never becomes a vacuum. Therefore when the turbos spin faster, the air has nowhere to go but forward increasing pressure in the piping. Increasing pressure at one end of the piping will increase the pressure at the other end equally as the pressure will disperse faster than the air can move. Therefore, the only turbo lag that would be possible would be from the elasticity of the metal piping, which isn't going to be much.

That kit for the Z06 may even be CARB certified.;)
