STS Turbo Kit

[mrk1]

A rear mount is a design compromise just like choosing between a low mount (AVO Style) or a high mount (FullBlown).

I would really like to experience one of these first hand before passing judgement like most people seem to do.

And I agree with empower-auto, since most people use these cars on the street for fun Im sure this would actually satisfy lots of people. Accept that its harder to brag about at the local show.

Well there are quite a few enthusiasts that feel different is better and the more "unique" your mods are the better they are. So I'm sure if it works they will have plenty of buyers to stay in business.

I just don't like their seemingly thrown together add ons (willwood, verdestein, etc)

Have the people complaining about lag experienced and measured it in real life? Turbos move air pretty darn quickly. A T3/T4 can move like 500cfm at full boost. To fill a 12 foot x 3" diameter charge pipe takes about .03 seconds at 500cfm. Certainly more time than a short charge pipe confined to an engine bay, but I can't say I'd be unhappy with that response time. Of course, there may be some variables I'm missing. This was just a quick calculation on my lunch break.

my issue with it isn't just that it's inferior in many ways as previously mentioned, but that said compromises are completely unnecessary on this platform. we have room to mount it where it belongs. it's rear-mount because they only make rear-mount kits, not because that's the way it needs to be.

i mean really, when was the last time an oem put a turbo where the muffler goes? there's a reason.

Also if you were to stretch out the piping from the typical intercooler you end up with a pretty significant distance as well, so considering the full distance from the rear isn't very fair. Some people claim this pipe under the car is enough cooling to no longer need the intercooler, so thats nice I guess.

However, it isn't just as simple as the intake charge pipe. You also have to deal with less optimal exhaust due to being at the end vs right off the header. (things like heat, pulses, etc) So, the turbo won't spool as fast. Its not just the time to fill the intake piping. Be prepared to not only deal with intake pipe leaks now but also exhaust leaks due to a system that typically wasn't designed to be pressurized now being pressurized.

Additionally, unless you run an oiless turbo, now you have to run oil lines to the rear.

So basically there are a lot of tradeoffs for essentially the single benefit of not having to change out the header. Hurray.

Rear mount setups have their place. Unless this kit is somehow cheaper than the AVO, that place remains with the v8 world. If it is cheaper, then idk, maybe some people could find it worth it.

Good points, I hadn't really thought about exhaust pulses and heat lost on that end. I agree there's not really any reason to do it on these cars other than perhaps weight distribution or stealthy street racing.

For a company that thinks they own the patent for rear mount turbo(s) in any automobile... EVER.
They are over a year late on this chassis.
@Roadstercycle Should sue file a suit.

On another note, while not for me. Some people would be quite surprised with the actual lag in a similar system.

The STS turbo for our platform has been around since over a year ago...

[mrk1]

^^ yup

Suggesting some equivalent effectiveness of the cooling potential for a volume of air moving in a standard intercooler to the volume of air moving in a length of charge pipe is pretty absurd. First, the pipe will create more static pressure (e.g., resistance) than the intercooler and cause the turbo compressor to work harder and heat up faster. Since the air velocity in an intercooler plenum is much slower than that in a typical charge pipe, it has cools faster. With fins and high velocity air striking perpendicular to the intercooler it further dwarfs any comparison with a long pipe under the chassis. I don't know what the delta comparison would be, but my guess is an order of magnitude difference. BTW, I am responding to an earlier post that I didn't quote.

I've heard an STS kit strapped to the rear of a 350Z. Everything else aside, it sounds like you're following behind a jet.

It's certainly a great deal of nonsensical fun.

[nonicname returns]

I need more info on this.
when will it be available and what's the price?
can you guys start a formal thread with info on this kit so that we can have it added to the turbo kit sticky?

my biggest and probably only concern with this is how close to the ground the intake is.

Yes, even the youtube videos it does sound pretty incredible
