the engine from an 2003 marauder or a 2004?

BAH! Forget the Supercharger OR Turbocharger...

just install one of these and it'll do the same thing...

I have an '04 but figured that the engines were the same. Is that untrue?

Can you run regular with this power adder? Does this disqualify you as being stock? If you cut yourself is the supplier liable? Will it lift the front end of the car if you go above 80mph? (common issue with these type mods) Will it suck cats into the intake from the sidewalk? It looks like it is turning the air the wrong direction for above the equator-must be made for Australia? Can it be used with a vegamatic? How loud is the turbine whine? Is there replacement parts list? Will it work on a craftsman 18hp riding mower? Is it teflon coated to keep the air from shearing the aluminum? Is it big enough to be used for tiaira? What are options, maybe jewel encrusted for Lincolns? And last of all how much does that thing weigh-must be about 40 lbs to cost 8.95 to ship...yeah I want one...bad...willie

Unfortunately, I can tell you from experience that a factory rebuilt engine, installed by a Ford dealer will cost you about 5K.

I am wondering if one out performs the other and are there durability issues to consider for both. How many members with these setups have had to replace engines because of problems caused by this modification? And how much would it cost to replace the current Marauder engine. I'm thinking if there is some sort of damage you end up with future beer cans as a result.

Warning: The below is not Marauder specific info.

First, there are two major types of superchargers. The positive displacement (think roots, lysholm etc), and centrifugal. Positive displacement superchargers will produce far more low end torque, but have poor efficiency at high boost levels. The centrifugal makes almost no additional bottom-end torque, but is much more efficient at making top-end high-boost power.

For absolute max power and torque, nothing beats a turbo. Since it uses exhaust gasses to spin it, the effective power draw is FAR less than the power a supercharger would draw at the same boost/flow level. For the most part, the energy in the exhaust of an NA engine is wasted, so this is almost like getting free power. The disadvantage of a turbo is spoolup. This becomes more noticable with high-boost small-displacement motors, but some of the more modern turbo technology is very impressive and minimizing this. When you stand on the gas in a turbo car, you don't get that instant, slam-you-in-the-seat hit of acceleration, because the turbo has to go from no-boost speed to full-boost, which takes a finite amount of time. Finally, for underhood mounted turbo installations, heat buildup can be extreme, as the exhaust back-pressure can get very high. Some of the turbo-Buicks get as much as 65 psi of backpressure in the exhaust. . .think cherry red headers.

For an example of modern turbo tech, though, take a look at the ecotech turbo. 18 psi, 9.2:1 compression, pump-gas, and non-existant turbo-lag.

Hope that helps a bit:D

I would go turbo, they have come a long way in the past 10 years.

Supercharging the Marauder is the best route unless you want to be a pathfinder.

If you looking to do a turbo you will need the following:

New engine-or forged bottom end.
New or Major upgrade in fuel system.
Depending on the state you live in C.A.R.B. II and vehicle emissions will be a consideration.
New-Safety equipment if you take it to the track under 11.50's
Built Transmission.
Upgraded rear end to include new axles
Possible new computer management system.

I probably forgot some other highlights, but you get my point. You want to go fast, so then I suggest you dig deep. If you want to play with the Big Dogs you will have to pay the price of admissions.

I probably forgot some other highlight...

A tubular front K-member and some other kind of steering rack so you don't have to run any exhaust tubing under the stock K-member....would be another one.

I've always wondered this myself but I believe s/c is the way to go. I hope to join the ranks of the fellow trilogy mm's soon.

Reading this thread I think of this......

:rolleyes:

My two cents:

There just is not a lot of turbo experience with the MM. There are only 2-5 turbo Marauders vs 200+ supercharged MM. Both power adders have the ability to "turn your engine in future beer cans".

Some of the Mustang guys are making HUGE numbers with turbos. The MM is a different beast, with some unique challenges (cross member, steering rack) and since the car weighs 4000 lbs+ it will never be the ultimate drag strip car.

"Ultimate" power adder, probably a turbo. But is it the best for the Marauder, I don't think so. I guess the real question is "What is the best power adder for me?" The board is full of good information from some very experienced users.

enjoy the ride

Not true- the same limits as SC's apply

New or Major upgrade in fuel system.. Not true- the same limits as SC's apply

Depending on the state you live in C.A.R.B. II and vehicle emissions will be a consideration. Same as SC

New-Safety equipment if you take it to the track under 11.50's .. the same limits as SC's apply

Built Transmission. .. the same limits as SC's apply

Upgraded rear end to include new axles .. the same limits as SC's apply

Possible new computer management system. Not true- the same limits as SC's apply

Currently only 1 full kit is available, but their may be some other custom options.

The PTS, or is it PTK, bolt on turbo looks interesting, does anyone on here have it? Too bad it's like $800 more than an s/c.

If you want bottom end torque to launch for drag's S/C..
Turbo for more mid range and top end power..
S/C is easier,more kits,parts and tuning..
Turbo 1 kit..Pro Turbo Kit any thing else your on your own..

Juno, with all due respect to you and your project I fail to see your point and edits. When Marauder owners are looking for power adders the horse power numbers usually run between 400-450. Kenny Brown advertised a conversion that would yield low 13 to high 12 second times. F.I.T, Trilogy, and REINHART AUTOMOTIVE have base model kits that don’t require the amount of modifications that you quoted me on. No one is going to purchase a 400 hp turbo kit for a higher price. I would expect a turbo kit to yield higher number based on the investment. I think their are a ton of members that would love to have a twin or single turbo system, but unless thief is a significant profit margin and demand, this will always be a dream. Turbo kits are not main stream for the Marauder family and fabrication cost are high. It really comes down to dollars and cents.

And....running exhaust under the front K-member, remember...which in my book is a big :nono:

Oh...and I'm diggin' the new avatar, my friend. Is that Lancelot Link??!! Now THERE'S an obscure reference for us older folks....

They go on sale occasionallly for 20% off.

You made it sound like you must do all those things to put a turbo on. You do not. You just have a to hold yourself to the same stock engine limits as the SC folks Now if you want to go crazy on power, a turbo will get you there cheaper then a SC kit.

In stock form the PTK kit makes more power then the stock SC kits for about the same price. The kit should also make well over 500 hp to the wheels with a fuel pump and injector upgrades. To do that with the current SC kits you have to make the same fuel upgrades and then spend money on pulleys, exhaust, etc.

Yes, some forward facing manifolds/headers might do the trick. Can you make some? :D

Once I get this single kit up and running I will have learned an awful lot and I will be looking at ways to re-route the piping and if anyway possible, squeeze some twins in there.

I really do appreciate the feedback. There is a upgraded Marauder in my future. I just wanted to know what $$ to establish for the install and what to expect on engine life after the install. If I can get a new motor for $5000, I plan to have that set aside after the install is done. And it looks like the SC is the route to go based on the feedback I have received on prior installs.
