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

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 :D

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.

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

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
