Turbo under our Marauder???

[Mike M]

Has anyone heard about "STS Remote Mount Turbo System???
As a professional mechanic I was at first skeptical to say the least. I was watching “Two Guys Garage” on SpeedVision yesterday and they were installing it on a late model Camaro. It’s a turbo that mounts in the exhaust at the rear of the car. They did a dyno before and after. It went from 269 RWP to about 400 rear wheel horsepower. The benefit is it leaves your engine compartment untouched except for the intake tube. Also no intercooler is needed as the under car pipes dissipate heat well enough.
I contacted the company and they do not make a kit for our Marauder BUT they make a universal kit that I may buy. I have to custom bend some exhaust pipes but I think it should work. I think it will cost about $4000.00 for at least 100 rear wheel horsepower.
I will keep everyone posted and if it works as good as I think it might I will offer the kit AFTER I talk to Logan. It’s too early to say yet but let me know of any interest out there.

I recommend you read up on it at this link. http://popularhotrodding.com/tech/0411phr_sts/

The problem with having a rear mount turbo setup is that the turbo lag is really dramatic over one that is in the engine compartment. You want your turbo as close to your intake as posible.

I watched that "Two Guys Garage" also. They specifically mentioned the lack of turbo lag with the system, but I don't remember how they explained not having the lag.

I'd sure expect prominent lag with this configuration. I guess you need a very low inertia (small?) turbine, and a high-stall torque converter.

Hey, someone has to be the first to try it!

[NAVCHAP]

Folks, remember previous threads about this product, there was a good deal of interest, but none of us have tried it. Can't remember when the posts were made. -kjs-

[sailsmen]

There is no real lag the way they set it up, turbos have come a long way in the past 20 years.

[blackf0rk]

Listen folks, I had a turbo on my Impala before my Marauder. So I know a little about them, and not from 20 years ago. If you're putting the turbo on in the rear, how is the boost going to get into your intake - magically? Of course not; it has to travel in a pipe; a pipe that runs from the rear of your car, to the front where your intake is. Now pressurize that tube with turbo, and you're going to feel it lag.

This system they have here is for individuals who aren't looking spend a lot so they can say they have a turbo. I would say that it would only be ideal for individuals who already have high HP cars off the lot - like that SS they have there - who cares about a little lag when your cars already fast? :):burnout:

but where could it be mounted in the rear? looking at the pics i wouldnt think there would be enough room between the rear end and the GAS TANK.:confused:

[Mike M]

I think the lag issue is a non issue. Assuming there is enough room for the turbo under the car (and I think there will be) I am probably going to give it a shot in the near future. I will document it and report back during the process. I like the idea of the price being less then 2/3rds of the superchargers and the 100 rear wheel horespower increase is from their "basic" kit. Their are 1 or 2 upgrades available that will equal the superchargers kits and still be cheaper and also much less labor intensive, possible 5-6 hours compared to 12-16 hours.

Check some of their videos on their website...doen't sound like lag to me.

P.S. I also own a turbo car, a 87 Buick ...now think about how little HP that V6 3.8L low compression motor makes without a turbo...maybe 150hp if its lucky...well it runs 12.87 pretty consistantly and it has NO lag. As far as needing a powerful motor before you turbocharge it, it's just not true.

"SHUT YO MOUF!"

Sweet deal Mike. Lemme know when you start toying around with this... I'd like to swing up and check it out.

I think that, even if there is a huge lag issue with this setup, it won't matter because our cars can get up off the ground as it is now. Imagine throwing this kit on a car with 4:10's and a torque converter. The lag would be almost non-existent due to the car revving up so quickly.

BTW... I've had a few toys installed since your last test drive. Care to take it for a spin?

[Mike M]

Who was the guy with the oxygen mask on??? I want to party with you! heheh

You have to stop up and say hi. I have been leaving the MM home until normal weather returns...this is why I am moving to Arizona.

Sounds like a very good idea. It surely is worth a try. If it's a success, you won't be the last. Good luck!

[dwasson]

If all you care about is quarter mile times, and you can spin the motor up before you launch, then lag won't be an issue. But in the real world turbo lag can make a car difficult to drive smoothly. Imagine what happens to your line when you are accelerating out of a turn and another 100 HP hits the wheels at an uncertain moment. You might be able to avoid some lag if you use a smalll, high speed turbo and keep it spinning at top speed most of time, venting over-boost at anything other than light throttle.

Like I said though, if you live your life in quarter mile bits you may not care.

[shakes_26]

Turbo Lag, I think they are adressing this by using what Volvo calls Light pressure Turbo-ing, in otherwords the turbo is designed to always be spinning at or near 'operational speed', right off throttle to redline, so that the manifold is always pressurized. It doesnt get rid of lag entirely but minimizes it. Land rover uses this in their diesel engines as well, actually diesels benefit huge from turbo. Also notice they are looking at 5psi boost, with an oh-boy setting of 7 psi.

The dyno chart starts at 2500 rpm, by then they add 100hp, I'd like to know what going on down there at 1200-2500rpm

I like the concept, lots of advantages, but also some negatives. For the Marauder, I'm still a S/C fan, and a roots/screw type at that. Now give me a Buick GNX to play with and I'll be a turbo man all the way. :D

The problem with having a rear mount turbo setup is that the turbo lag is really dramatic over one that is in the engine compartment. You want your turbo as close to your intake as posible.blackf0rk's right on this issue but it's not because the charge pipe is so long. It's because the exhaust into the turbine is a lot cooler at the back of the car. Long charge pipes are actually a good thing and you might even be able to get away without an intercooler with a long one.

Boyle's Law states that a gas will expand when heated and contract when cooled. For maximum response, the distance from the exhaust port, where the exhaust is at its' hottest and therefore at its' most expanded state, to the turbine inlet needs to minimized as much as possible.

I wouldn't dare try to install a "universal" turbo kit on my Quicksilver. But I am a fan of turbocharging (I used to work for Buick) and I have been toying with the idea of getting Pro Turbo Kits' Marauder kit. (click here (http://66.70.20.245/store/scripts/prodView.asp?idproduct=78) for the site) It comes with the best hardware, 42 lbs injectors, Lightning MAF sensor and a high volume fuel pump. Using a Garret T-64E (700 HP ability) and short tube headers with 1/2" flanges, it sounds like a well engineered system. I think I'd rather use a tried and tested system with dyno numbers to prove it than start with something that's obviously inferior from the get-go. They're claiming 371 HP and 471 torque at the rear wheels (That's about 100 extra crank HP) on 7 lbs. boost using an air-to-air intercooler. That's a driveability asset, no bags of ice to buy.

The only thing that's been holding me up is the idea of a twin turbo set-up like the one Gale Banks has for the mouse motor. (Click here (http://www.bankspower.com/twin-turbo-products.cfm) for the site) There's a very good pdf to download there that explains a lot about how to make a no-lag turbo system.

So my project for this year is to find out if a twin turbo system like Gales' is possible for our beloved Marauder and if it is, do it on mine. If not, I just might go with the single Pro Turbo Kits system.

[DEFYANT]

A turbo MM...? I hadnt considered that. And that kit is cheeper too... hmmmm

I'm supposed to call a guy there and discuss the twin turbo idea soon. I will definitely let you guys know what develops.

[MENINBLK]

I only have one question.

Where do you run the oil line to lubricate the Turbo ???

[torinodan]

there was a marauder on auto trader that had one of the Pro Turbo kits on it. never got to call about it. did anyone else see it?

[Krytin]

I only have one question.

Yeah, and what does it drain back into?!

[Macon Marauder]

I saw some of that episode. The kit came with a pump and high pressure oil line. Looked kinda like a remote mounted oil filter set up.

They were explaining the lack of turbo lag when my kids came home so I didn't get the details. I think the dyno chart showed that there was very little or no lag. The graph was much steeper than stock without the quick drop off in torque.

The custom kits look sweet. I'd be cautions about the universal version, though.

[David Morton]

I talked to Dalton Campbell at Pro Turbo Kits last Friday and he said they could build any kit I wanted but they would need the car and it would be more expensive, of course.

Right now I'm leaning heavily in the direction of the single Garret T64-E kit they have right now.

The hell with that Mike, throw that Chevy motor you got in it.

[Constable]

It'd be a pitty to pull that motor out of it's current home... (droool).
