Rear mounted tubo on V8's? Any good?

[Eimaj]

I found this company selling rear mounted turbo systems for my car soon. Pic of the system is attached below.

Rear mounted (ex. where the cats are) seems odd to me? Anyone ever seen this type of setup work?

How would this system compare to a front mount turbo?

[StupidBikerBoy]

Saw one of these kits installed on a vette on one of those sunday afternoon spike tv shows. I remember him saying that it only lost about 1 psi through all that pipe, but also cooled the intake charge a lot more than the conventional turbo setup.

[Z0_o6]

seems to me it would have a ton of lag.

[Eimaj]

I'm thinking about trying it out.

It just looks like an odd place for a turbo.

Plus, its a hell of a lot cheaper than a Hennesey kit.

There is a company that does rear mounted turbo setups that are really nice. They had one on a GTO that they ran in a top speed shootout that made over 600whp. With a small/midsized turbo on a large displacement V8 there is very very little lag. But the benefits are generally a charge temp about 50 -100 degrees cooler by the time it reaches the motor. The temperature drop far outweighs the losses from the remote mount. If I had a late model V8 and was looking at making some big power I would definately be running a remote mount setup.

[99SeanWs6]

they're pretty good from what i've seen on the LSx and LT1 engine. with supporting mods you will make alot of power

[C.K]

STS makes quality stuff. In the beginning everyone on LS2.com was skeptical and would bash them, but since then they have been consistently putting down solid numbers reliably. So, in short, yes they are good. :goodjob:

[SampaGuy]

seems to me it would have a ton of lag.

it wouldnt lag very much more at all, a big turbo can flow that much air in like .01 seconds

[lata]

I live about 1-2 miles away from STS (squires turbo system). I had couple of friends that works there.
First off, Great Idea, no need for much mods(only if your ECU compensates for increased air)
2, Utah has snow... turbo and snow dont like each other much.
3, they dont offer (they didnt when i was there) fuel management due to liability.
4, 2 friends had it, great topend, they took it off because it leans out. (they bought the stock set-up that claims to be fine with stock management)
5, 1 friend has it still on his integra(he loves it), but his motor is built and has fuel management and his turbo is a small dual bb (very fast spooling, which compensates for lag), all he was from them is the set-up(pump, turbo, pipes) and he did the rest to make it reliable, he was making about 250hp becuase he wanted a more balanced weight and have more power from 4-8K.
6, when changing the oil, you dont change it all out, it leaves about 1 quart in the lines that it runs to the turbo and the pump to return it.
7, turbo stays cool and puts the weight of the turbo in the rear rather than the front.

PLV, it is way laggy if you put a big turbo to them.
The company still young, they are still revising. if anyone goes for one, just do what my friend with the integra did and you mostlikely will love it as much as he does.

I read an article about 2-3 years ago about this company. They had installed the kit on an ITR and saw substantial numbers. They sad lag was almost none existent and cooling benefits made up for what lag was present. Only problem i would have is protection of the turbo. I mean, puddles, speed bumps, pot-holes, etc. and you could possibly be out a grand or two. I guess if they get popular they should develope skid plates.

[lata]

the yellow ITR was STS, then the owner got rid of it after the magazine appearence. He ran a modified version of it. the turbo was right after the header...if that makes sense... anyways, he now owns his own company doing turbo set ups. he's got a turboed NSX right now. tis the sick

Heres a c5 w/ twin rear mount turbos. He ran 13's, lol. It was too much power for his tires....very traction limited.

[Killer]

i've always been told it's not as effective.. something about the air being warmer some how.. i don't remember details.

[ranj]

Saw one of these kits installed on a vette on one of those sunday afternoon spike tv shows. I remember him saying that it only lost about 1 psi through all that pipe, but also cooled the intake charge a lot more than the conventional turbo setup.

saw the same thing too. and the old guy was making funny turbo spooling up noises lol.

if you spec the turbo out properly for a rear mount setup then it can work ok, but you will still see better efficiency through a normal mounted turbo setup. i just hate the idea of 15 feet of intercooler plumbing and a remote pump to return my turbo oil rather than good trusty old gravity... just a whole lot more shit that can break IMO.

[ranj]

but that extra piping cools the compressed air!! benefits and drawbacks. i say go for it!

[Master Shake]

seems to me it would have a ton of lag.you can reduce the lag a lot by running a smaller intercooler piping.

but i don't know about this kind of shit. i never worked on a V8....str8 4 bangers

[iloveboost]

I understand HiPSI's concern, but at the same time... you get more weight down low, and in the back where the weight is more desireable.

Pros and cons to it all.

I've heard firsthand where people using rear mounted kits enjoy them with no complaints.

[Jaimecbr900]

Why not just mount it on the front? Seems to be lots of room under the hood to fit one. If I fit one under my hood, you should be able to rather easily. :thinking:

[ranj]

wasn't this kit meant for the new vettes who had no room in the front?

[Fast Shadow]

I've driven an LS1 Z28 with an STS kit and it was great. No lag to speak of.

[Jaimecbr900]

wasn't this kit meant for the new vettes who had no room in the front?

Exactly.

I see no benefit from using a kit like this unless you just have zero room under the hood. It was probably designed for that purpose. The performance pros and cons aside, if at all possible why would you want an extra 15 feet of piping running under your car if you didn't have to? It's not like 3 in pipe is all that easy to tuck underneath a car already. Why would you want more stuff possibly scrapping the pavement?

Seriously, if you don't have the room is one thing. But if you do, why bother?

[Fast Shadow]

Because it's really easy to install and remove and solves a lot of heating/cooling issues by moving the turbos out of the engine compartment.

[ranj]

Exactly.

true dat, but i still say go for it.

[iloveboost]

And also... it's much easier to get to little things like spark plugs and doing minor work to the car without manifolds and charge piping in the way.

[SLow_POke]

at school we bolt one of theses kits on a shop car pretty DAMN easy on a new GTO.

was great till the other class blew the motor. im gonna try and look for my memory stick to post some dynos. for kicks

[Jaimecbr900]

I'll be able to see just how easy it is to install since my buddies are about to put one on a Z06 soon. :goodjob:

Most cars are not going to have issues with general maintainance at all. Most piping is not in the way of most things that require regular changes.

I'd still like to see how the piping is ran back and forth under the car. I know that's always been my only issue in my car. It is very easy to scrape if you're not super careful.

I still think it's a cool idea for a car with no room under the hood.

[iloveboost]

STS TT kit on a C5Z06. This guy had a front mounted TT Z06 and now has the rear mounted STS TT kit and loves it much more.

753rwhp @ 11psi.

[Jaimecbr900]

I was told the other day by my buddy who's doing his that the piping runs thru the inside of the rails. That would explain and obviously fix the clearance issues I thought about. The Z06 is so low to the ground already that the stock pipes run inside a channel with the driveshaft running back to the tranny. It's like uber flat up under there.

[ranj]

i thought they ran tucked in near the skirts, but don't take my word for it, just what i think i remember

You're right. That's what I meant to say. My bad. It does run thru the skirts up the front.

[JstAneon]

We have a ws6 in ECB running this setup. I think he's making well over 700whp.

Just saw this.....cool video. That's a hellva improvement on the WHP. Very nice. :goodjob:

[boostboy97]

The first pics in the thread looks like its a single turbo setup and if so there wouldnt be a huge amount of pipe going under the car. You could run the exhaust into a single pipe then to the turbo , then run the intake charge pipe back to the throttle body. This way sounds the easiest to me, please correct me if im wrong .Has mainstream fabricated anything like this ?? just curious

[Halfwit]

Saw one of these kits installed on a vette on one of those sunday afternoon spike tv shows. I remember him saying that it only lost about 1 psi through all that pipe, but also cooled the intake charge a lot more than the conventional turbo setup.
and also of cars with v8s, it creates lag, witch is good for traction. get hte power whene u need it.

[Big J]

It'a a hemi for fucks sake, it's not a 4 cylinder. Turbo lag is a mute point when you make 200+ ft/lbs at 1000 rpms, lol. I thought about doing this on my car, but I couldn't figure out an economical way to do the oil return. Any where you put it it'll make power if the turbo is sized correctly. It's got its pros and cons, but they will make sick power.

[On_Her_Face]

ya i really want the sts TT for the new vette, but ill probably end up with a sc in a year or so

[Mr.MuayThai]

I KNEW I SAW A Z28 WITH THAT SET UP! LOL! I thought i was going crazy! i do remember it hauling ass! but i still see the car running up and down the road aleast once or twice a week so it seems like it is affective... i'd say go for it bro!
