Rear mount turbo

[fhudsonjr]

Just checking to see if anyone has tried mounting a turbo at the tail pipe.

Ststurbo sells kits for more popular makes of cars and has had some very good reviews in a couple of car mags. Their web is www.ststurbo.com.

Uh no. Not for our cars. Why even bother when you can bolt a big ol turbo right in the stock location.

Where do you start.?

I'll let someone else point out a few of the more major flaws with this setup, and instead, I'm going to focus on the positive....

My dogs would have a nice warm place at the rear of all my vehicles.....

It would solve a few mysteries I've always wondered about....like how to get hot and frothy oil to drain uphill....I've always had problems with that.

But, most importantly, it could keep my petro-mizer molecular optimizer company...(patent pending :rolleyes:)....I banished the optimizer system to the rear of the vehicle when it failed to perform up to design specifications. Maybe the two of them could discuss cold fusion and it's application in the automotive arena. The field is wide open.....stay tuned for further developments....

maybe he is a 3rd gen guy..it was in the non-turbo section

Stacy David on Trucks seemed to think it was cool....I love that guy!

If you want to try something different, go for it. I don't like to discourage people from trying new things. However, you're going to run into some issues that will probably have you wishing for a more standard/normal setup. Upon saying this, I must admit, I haven't read the aforementioned article, and so I don't know anything about that setup.

The biggest thing I can think of is how much extra piping you'd have to fill with air between the turbo and the engine. I think you would not like the spool characteristics of such a setup. You'd also have to build some sort of shield or box for the air intake and then you'd probably want a GM MAF/MAFT setup in blowthrough because there's no room in the back for any sort of MAS. You'd also have numerous other headaches to deal with.

Now, if you were to put a turbo in the rear of the car because you've got the engine back there too, that makes perfect sense (think Porsche Turbos, etc). I guess you could also put an extra engine in the back! That way, you wouldn't need a transfer case or a driveshaft. That would be a SERIOUS pain though because you'd have to make sure everything was completely in-sync.

Now that would be fun. You'd also have great weight distribution, although the car would weigh a chunk more to start with.

My answers are meant to be lighthearted and good-natured in their intent. However, if you've got the patience, money, confidence, skill, adventurous spirit and even more patience and money, I say, go for it. Just don't ask us if we've ever done it and how to do it because as far as I know, not a single person on this board has done this before (but I've been wrong before).

The only reason I can think of for honestly trying something like this would be to distinguish yourself from the pack. I don't consider myself a lemming, but in this circumstance, I'm more than happy to go along doing it the same way as others. It's not that it can't be done, it's just that I don't want to be the one doing it.

I have big dreams and crazy aspirations from time to time, so if you really, really want to do it, go for it. ;)

There was a twin engine Hyundai that was the ultimate street sleeper. One engine upfront driving the front wheels, and one engine in the back, driving the rear wheels...too cool....

And, I still remember the Renault r-5. Basically a le-car with the motor where the back seat was...stupid fast little car....

But, speaking ONLY for myself, every time I try and reinvent the wheel, it comes out something less than round. I've decided those wily production engineers at the factory know waaay more than I ever will, and I'll just make "improvements ;) " on their designs...

if you're talking about the tiberon in sport compact car a few years ago, yes that thing is fast( and does some wicked awd burnouts), back then it ran a 10.6 1/4 mile. I dont believe it did that well in SCCs ultimate street car challenge.

[fhudsonjr]

No, you haven't been doing it all wrong,but maybe, just maybe there is a different way of turbo charging.

Don't be afraid of the new just because it sounds so implausible. How about reading the articles In Chevy Hi-Performance,Corvette Enthusiast,Gm High Tech Performance,Mustang Monthly,Motor trend,Import Racer,Hot Compact & Import,etc. about STS turbo and how it works before you pooh pooh the idea?

Yes, I'm an NT 93 Talon just looking for more power and something different.
Thanks for your comments. Even those not in jest.

If your running a 1g I'd stick with the under the hood turbo the rear mount isn't really going to work since there's no room and the gas tank taking all the room behind the rear I-beam. just more practical I wouldn't risk the problems on a major performance mod just to be "different" I guess it's just my opinion.

I almost forgot. Yes, it will keep your dogs warm and PETA will like it because cats won't get chewed up by timing belts, since they'll have a safer place to sleep. :)

Interesting idea. I will have to read up on how they accomplish it. But I agree I don't think there would be much room under our cars back there.

They work. Well. See this thread:

This car is using one of the first STS universal kits utilizing a single turbo. The production kits use two. The car's bottom end is built, but at 13 psi the power made is unbelievable.

Of course there are better less expensive ways to convert DSMs without turbos, but I don't see why a NT couldn't install a system similar.

Having driven an F body with a kit installed but untuned, I was surprised at the quick throttle response and absense of any lag. It hit pretty hard.

The car I drove had no intercooler, and if you think about it, one 2 1/2" or 3" tube from the rear of the car to the front contains roughly the same internal volume as a large front mounted intercooler.

I understand all the naysayers and the arguement that turbochargers work with heat as much as with airflow. You'd think it would be much less effective than it is.

The really cool thing is, it's something no one has really tried before on a mainstream level. They seem to be doing well with it.

I think that Corvette is pretty impressive. The video of the 9.33 second pass is in that thread too.

[Hal]

Remember, a typical V8 has twice the exhaust flow (volume), and that's going to help spool up.

Regardless......ANY 9 second car that is driven to the track is extra impressive in my book. Number of cylinders doesn't really change that.

That Vette 60 foots like Shep too....

[Splicedgene]

wow thanks for the insight jason. So are you planning on trying it? :-P

[eclipse92gsx]

I'm still skeptical about the intake routing and oil lines and everything having enough room under our cars... but it'd be cool if you prove me wrong so please go for it!!! :D

I'd love to try it, as soon as I find $6k for a kit. *koff koff koff*.

We're installing a kit on a certain GTO soon, I'll report back as to how that install goes.

I believe he's going with a front mount and possibly a larger-than -stock turbo. A stock LS1 will take 500-550 rwhp on the stock internals before it gives up.
