Rear mounted turbo kit

kannibul

The thing that gets me is that people are strapping on a turbo (or any other forced induction) to an engine that has 11:1 compression. That's just asking for it to blow up...

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?

Your assumption on the compression ratio is not accurate. HRs run 10.6 compared to the 11.0 in the VHR and they (HRs) have been boosted successfully for over a year with 10+psi. For the record I only know of 1 failure reported (my 350z .com forums) since the HR turbo kits came out. The VHR, despite the 11.0:1 compression with boost just fine and VHR have stronger rods than HR too.

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

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.

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:

Thats dumb ... i think

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.

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

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.

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.

That kit for the Z06 may even be CARB certified.

Crash

It's possible. But I think I'm going to go with a supercharger. Techco is making a 3.0L supercharger kit that fits under the OEM hood. I'm thinking that'd be better since I won't have to modify the crap out of my car. We'll see, though. I don't really want to build the motor, but with the amount of power the 3.0 CAN put out, I may do it anyway.

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!!!
