Rear Mounted Turbo For V35

[THE_350GT]

Hi Guys,

Not sure if this is a re-post but though it was very interesting from one of the guys on the G35 US forum rear mounting a turbo with some surprising figures.Apparantly only costes arond the 5-6K US

[WazR32GTSt]

1) horribly inefficient use of pipework

2) turbo is near the fuel tank (this can't be good in an accident!)

3) what happens when the exhaust side of the turbo gets water on it from a puddle? (i imagine the metal would crack)

4) what happens when you go into shallow water and the turbo gets flooded with water? (i imagine the turbo would shit iteself)

5) no muffler?

the list goes on...

i would be SHOCKED and AMAZED if this was actually for real and if it ever passed an engineer's test

[Chris Rogers]

can anyone say LAG.....

looks like a tightarse way of not doing it properly. HKS kit would have been a better idea.

this is f**king stupid.

this is f**king stupid.

^^ What he said!

A few months ago a friend of mine with a srt 300c, showed me pics of a twin turbo 300c with a very similar set-up. New US fad?

[wolverine]

there is a monster thread here from a US BMW forum that is worth a read.

Its done out here also - a few guys over at ls1.com.au have the rear mounted turbo set up on their LS1's

They have had some good results also......but I don't think I'n conviced yet like you guys

with the turbo so far from the exhaust manifold it would take ages to spool up as the gases would have cooled and slowed by the time it actually reached the turbo. Is the engine bay of the V35 that cramped?

[scathing]

Yeah, I've seen a couple of reviews of this STS turbo kit, and they reckon its not that laggy.

It defies all thermodynamic principles, and makes your turbo piss-easy to steal, so its a "grain of salt" kind of deal. Its something I'd certainly want to test ride in before I put down my own cash.

I can assure you that STS is for real. Here's their 350Z dyno:

Here is a US 350Z owner's experience with it.

So it would act like an NA until the Lag was overcome...

I'm not sold on the idea... it would be ok as you could get a NA like responce, while you wait for the exhaust to hit the restriction (turbo), then have it spool up... and provide more power.

The turbo would also get less "pulse" effect from the exhaust and more linear flow.

i would have a guess that it's not a overly huge turbo, and would not be ideal for major power figures.

but kudo's for the idea... i'm still agreeing with the afore mentioned flaws though!

Some questions and answers by STS

With the turbo located in the rear of the vehicle, is there turbo lag?

No, due to extensive engineering and proper sizing of the turbos and piping, the turbochargers operate very well at this remote location. All of our systems will produce full boost below 3000 rpm. If you were to take a front-mount turbo system and place it at the rear, you would have lag issues, and similarly, our turbo system wouldn't work properly if front-mounted. Also, our intake tubing volume is about the same as most conventional turbo setups that are running a front-mounted intercooler, and is less than many of them that run large intercoolers. Our system is not like a small compressor filling up a large air tank, it is like a huge compressor filling up a very small volume. Our systems compress the intake tubing in about .05 seconds. If our patented and innovative rear-mounted technolgy had problems with turbo lag, we would not have the large number of happy customers that we have today. Please visit our Testimonials page for more insight.

Does water get into your engine due to the filter location?

No, every kit includes either a snorkel kit (which locates the air filter high in the rear quarter panel) or an air filter shield. We also include an Outerwears Dry Charger which is proven to protect the filter under very dusty or wet conditions.

Without a muffler, how does the vehicle sound?

The turbo does an amazing job of muffling sound. Most people think it sounds like a performance muffler. You can still add a high flow muffler to the system, but most of our customers like the performance sound with just the turbo.

If water hits the hot turbo, will it crack?

Seems like it might when you first think about it, however, when I asked the Garrett engineers this questions they just laughed. There is a big difference in water splashing on a hot turbo and submerging it in enough water and fast enough to really cool it down fast. Both the new turbocharged Vette systems and the new Porsche systems sit the turbo down low and exposed to water and anything else that goes under a car.

Plus, our turbos just don't get that hot and when weather conditions are such that there is a lot of water around, you can't push enough boost to get the turbo hot anyway because you'd just spin the tires.

Apparantyl also there ore some covers for the pod and turbo that still need to be installed.

Some vids of STS pretty cool idea

there a a couple of 6sec 7sec cars in the states that have there turbos in the boot because they are to big and cant fit in the engine, garret had a mustang drag car at sema with there new 2000hp turbo, the mustang had two off them mounted in the boot.

also it would work because the piping can be straight to the cooler as opposed to bends
