Can you supercharge a Marauder and still keep it a daily driver?

[Motorhead350]

Ok I was wondering this because I have heard mixed opinions on this. I want to put a blower on the marauder, 4:10 gears and a few little things. Will the car still be dependable and go over 300 miles on a tank of gas? I heard you can adjust the boast for the street then the track. I have a K5 Blazer and now it's pushing 400hp and isn't dependable at all. I just blame a crappy job on rebuilding the engine. Anyway I heard the Marauder might get that bad and would be in the repair shop more then my garage if I still used it was my daily driver. Is this true? :help:

absolutely! my car can be driven all day with out going into "boost" mode. on the highway with the cruise set at 70 mph, the car pulls 12 inches of vacuum. my fuel consumption is unchanged under everyday driving conditions. a supercharged mm is a great daily driver!:)

Yep, there are plenty here in Chicago that can prove that and many around the country. I'd say you are lucky to be here because between Chicago and Detroit there are probably more blown MMs than anywhere. 300 miles per tank? That's all relative. I didn't get that stock, I'm way to heavy on the pedal to get much more than 260 - 270. Don't care either or I would have bought a different car.

I'm very happy to hear this but what was the cost? like $7,000?

[Tallboy]

my kit was $5995. install prices vary with who does it...

I had the same concerns but got a chance to test them. Read HERE (http://www.mercurymarauder.com/forums/showthread.php?t=8262).

70 MPH, who drives only 70 mph. Chuck, is your vision going or something? I'd of expected at least 80 mph out of you!

A new less expensive kit is coming out as well, check the threads. Any S/C is an awesome power adder. Just depends on what you want. Search those threads as well.

Thanks......I must say I enjoyed re-reading that post once again......Tom

Anyway I heard the Marauder might get that bad and would be in the repair shop more then my garage if I still used it was my daily driver. Is this true? :help:I installed the Trilogy Supercharger when my 2003 Marauder had 11,000 miles on it, and now it has 20,000 miles on it. And during the 9,000 miles I have put on the car since I've installed the Supercharger, it has driven, run, and behaved perfectly normal. And this car is not only my daily driver for back and forth to work, but it's my only car. Whoever told you that S/Cing your vehicle would make it exhibit poor driveability does NOT have any experience w/cars that have been equipped with a quality supercharger kit. I even have 4.56 gears in the rear end of my Marauder also, and on the last interstate trip that I took w/it (which was a few weeks ago) I got exactly 335 miles out of a tankful of 93 octane gasoline. And that's with 4.56 gears!!!

However, I must tell you that this was completely all highway miles, and that I don't usually get that many miles out of a tank of gas since I'm usally getting very much into the gas pedal often!!! But on that day I was driving mellow. But if I started my car up and let it sit there w/the engine idling, you would not know it's supercharged, nor would you know it's supercharged even if you drove it, if I didn't tell you it is, and if you didn't go past the first one third of the throttle position. Once you get to about half pedal, the boost pressure really starts to kick in, and you know by the way the car is moving that there's something serious going on!!!! I luv it!!!

And it absolutely has not effected the daily driveability of this car at all. My one suggestion to you is if you do decide on a Supercharger for your Marauder, get one that is included in a complete kit from one of the vendors here. Perhaps you already know this, but if you want an Eaton roots type S/Cer, then go to Trilogy Motorsports for that (see that forum on this board) like I have. But if you would rather have a centrifugal S/Cer like some guys do, then that can be obtained through a vendor on this board too. And from what I've heard, will also offer good daily driveability too.

And just a little more info for you here....there are 58 Marauders that are equipped with the Trilogy Motorsports roots type S/Cer kit, and I believe just under 30 Marauders that are equipped with the centrifugal S/Cer kits (also from a vendor of this board). So you would certainly not be one of the first satisfied customers to have and drive a S/Ced Marauder.

GREAT POST, BILLY :high5:

[Motorhead350]

wow thanks a lot. I was hoping for that and yes when I was saying 300 miles on a tank of gas I ment highway miles. I just put 63,000 on mine last weekend. Mostly highway.

[duhtroll]

Wow -that's a lot of driving for one weekend.

Not counting stopping for gas, you were driving 1125 MPH from Friday 5pm to the end of the weekend. (or so)

What the hell do you need a S/C for?
:P

And, I think the original question is referring to longevity, not initial driveability. We won't know that answer until someone has put 100K on their S/C MM.

Anyone?

:D

-A

EDIT: PS - I should add that you can adjust the boast on any S/C MM every time you improve your times at the track. :cool4:

[Motorhead350]

it took 2 years not 2 days to reach 63,000 miles . doing it in 2 days sounds like fun though :burnout:

[Logan]

In short, absolutely positively yes. :)

335 miles on a tank of gas is 16.25 MPG. I get 22-24 MPG, must be them 4:56 gears, eh?

Billy...You forgot Kenny Brown again, add about 50 more Vortech/centrifugal builds to the S/C database, eh? Yes, I know Kenny Brown doesn't sell S/C kits, but it's still a supercharged Marauder, yes? many have chosen that route too.

335 miles on a tank of gas is 16.25 MPG. I get 22-24 MPG, must be them 4:56 gears, eh?Yep. I just mentioned that since the first post had brought up a question about being able to get atleast 300 miles to a tank of gas.

Yes, I know Kenny Brown doesn't sell S/C kits, but it's still a supercharged Marauder, yes? many have chosen that route too.LOL..... Yes, I kinda thought you would mention that. No argument there.

I wish I knew the secret to getting better mileage. Most of my miles are highway miles and I find myself getting 16MPG consistently. Is it possible that a consistent 85MPH with 4.10 gears is enough to affect the mileage that much?

Does an automobile with a roots unit will get worse mileage than the same automobile with a centrifugal unit? If you're into the boost at a lower RPM, surely you're fuel consumption is higher at said lower RPM. Just curious.

[MarauderMark]

15k and so far so good.. :)

[BillyGman]

Is it possible that a consistent 85MPH with 4.10 gears is enough to affect the mileage that much?I'm gonna assume that this is a serious question.....I think that getting 16 MPG driving at a consistent 85 MPH is pretty good gas mileage w/4.10 gears. If you're that concerned about gas mileage, then I'd say that it's time to slow that 4,200 LB Mammoth down to 65 MPH. I'm sure you'll see better gas mileage then.

Does an automobile with a roots unit get worse mileage than the same automobile with a centrifugal unit? If you're into the boost at a lower RPM, surely you're fuel consumption is higher at said lower RPM. Just curious.I don't agree. I'd say that can't be true. Atleast not for the reasons that you stated. The roots S/Cer will deliver greater boost pressures under 3,000 RPM's, and probably even greater ones under anything below 4,000 RPM's as well, but ONLY IF you're at FULL throttle. With the stock throttle body hooked-up to a roots S/Cer, as long as you keep the throttle position less than half pedal, then you won't be into the boost pressure anyway.

And even at half throttle, you won't be over 5 PSI of boost. So it all depends on how much you want to unleash the monster that Lurks under the hood. When you drive mellow, you'll get the same gas mileage as I'm sure you would with a centrifugal equipped Marauder when it's driven mellow.
