S/Ced vs. moded N/A what to expect:

[BillyGman]

In some of the threads I've participated in on this board as of late, a few people have indicated that they attribute the respectable 60' and 330' times that I've run with my Marauder at the dragstrip to the 4.56 gears I have as well as to the 3,000 RPM stall speed that I've chosen for my car. However, while I agree that the gears definately make my car quicker in the initial 1/8th mile than other 400 RWHP Marauders are, the Trilogy S/Cer has been just as much a factor, if not more so.

I want to show everyone what my times were with the 4.56 gears and the 3,000 RPM stall speed BEFORE I installed the S/Cer, as compared to AFTER the S/Cer installation ...... so let's compare my modified N/A times, to my S/Ced times at the track.(These two runs were both performed with 93 octane pump gas alone, at the same time of year, and at the same track, and I had excellent traction in both runs from start to finish).......


Modified N/A: 4.56 gears,.................... Supercharged: everything
Kooks headers & exhaust,................... from before + the Trilogy
P.I. converter w/3,000 stall ................S/Cer w/9.5 PSI of boost

60' - 1.99 sec .............................. ......60' - 1.65 sec.

330' - 5.59 sec........................... ...... 330' - 4.93 sec.

1/8 .............................. ...................1/8
mile - 8.63 sec........................... ....... mile - 7.65 sec.

1/8............................. .....................1/8
MPH - 79.96......................... ........... MPH - 89.70

1/4 .............................. ....................1/4
mile - 13.51 sec........................... ...... mile - 12.00 sec

1/4 .............................. ....................1/4
mph - 101.07........................ ............ mph - 114.25 (13 MPH increase!)

Thanks BillyGman,Of all the active members here .you are making the most of the available power on tap.

Seems you enjoy dominating your "local streets" more so than the drag strip.
Can you give us your impression of the stall and gears.
you've said if the Trilogy came first, you may have chosen(or been satisfied) a smaller gear or left the 4:10.

Seems you enjoy dominating your "local streets" more so than the drag strip.Yep, it's a daily driver, and also my only car. So not only am I very satisfied with how it moves, but I haven't any intention of modifying it anymore than it already is. I've made 20 passes at the dragstrip with it. So I know exactly what it can do, and I have nothing more to prove with it on the track. I love driving it on a daily basis. It runs on nothing but pump gas all day, every day, and it's a blast to drive on the street.
Can you give us your impression of the stall and gears.
you've said if the Trilogy came first, you may have chosen(or been satisfied) a smaller gear or left the 4:10.The stall and the gears? Well, it's real cool having 4.56 gears and a roots S/Cer on a street car, because no other daily drivers can keep up with it (especially from 0-80 MPH) however with those gears you do sacrifice a little bit over 100 MPH. I went with The 3,000 RPM stall only because the car was a slug off the line, and from a traffic light before it was supercharged, and I didn't think I would ever S/Cer it. So I bought the converter w/the higher stall speed in an effort to get the tank to move off the line, but I still wasn't satisfied, although the converter was a decent bang for the buck.

But had I known I would end up getting the Trilogy S/cer kit, I would've left the 3.55's in it. 4.10's are the best street & strip compromise though (yes, I tried those too). But it's a trade-off since the 4.56's will give you the best 1/4 mile ET's, as well as the best 0-80 MPH times on the street.

[Bradley G]

On the street can you gas and go, or do you , roll out a bit first?

I won't lie, If I was as close to eleven second quarter mile as you , I would persue one tenth reduction in ET's just for bragging rights!
But I guess that say's something about me, that I am not that proud of!
I commend your disipline!

Very informative post G-man!!! http://mercurymarauder.net/forums/images/smilies/thumb.gif

BillyGMan,

Thanks again for the input on this. You gave me the same information in a PM about a year ago. I really keep thinking about doing the 4.10's next year, but I also know I will go S/C at some point in the future. It is just a matter of when. I keep wondering if I should just do the 4.10s while I am N/A and enjoy it for the next year or 2 and then do the S/C. Then again, wondering what the hit to gas mileage will be and if it would be worth it if I am going to S/C anyway.

Then again, TallBoy said he did the S/C only with stock gears and is VERY happy. And I do plan on the Trilogy instead of the Vortech or F.I.T. Kit (nothing against either of those setups, just made my decision on the Trilogy).

OK, I am done rambling. I will just focus on the new header back exhaust I want and leave the gears alone. She runs plenty good for me right now.

[Marauder2005]

Wow those are great times for a N/A Marauder, as well as the S/C times...

Good work in both aspects :coolman: :cool:

[Tallboy]

I did my car up the way it is now because of the direct input of Billy and Carfixer. Getting the S/C as my first mod was the one of the smartest things I've ever done. In the long run I saved a bunch of money doing it this way... :beer:

I would have to agree with this. I guess why throw money at things that give minor improvements when you can save for what this car needed from the get-go - a supercharger.

I do want the exhaust either way for myself. Other than that, money will be saved for the Trilogy.

Thanks to Billy and all you other Supercharged guys for your continued input on what you have, why you did it, what order you did it, and how you would do it if you had to do over. It helps those of use just starting out.

Ditto. The most I've done so far is program, gears and CAI. I was planning on doing the torque convertor, but I've come to realize that there's only one thing that will cure my need for horsepower, and that's a S/C. So I will continue to save my pennies and one day...:burn:

It helps those of use just starting out.You're welcome my friend. And that's exactly why I post things like I have in the opening post of this thread. Just to be helpful and informative, and not to brag. I've enjoyed driving this car so much since I've supercharged it, that I like to share that joy with other Marauder owners, and convey to them how much of a difference S/Cing has made, so that they too might experience the same thing as I have with their Marauders.

[BillyGman]

On the street can you gas and go, or do you , roll out a bit first?

!On the track I can just punch it all at once, and the Nitto tires grab off the line real good, which was the same with the stock tires when the car was N/A and I was turning 13.5's with it, since it didn't have the low end torque back then to spin those tires on the dragstrip due to the VHT traction compound they always use. But on the street, I have to walk it out of the hole using half throttle and just dipping into the boost a little bit for the first 20 feet, and then right before it hits second gear, I can hit full throttle, and the drag radials grab.

If I use the stock tires on the street, I cannot get into boost at all in first gear w/out spinning them, and I have to walk it out of the hole with less than half throttle for the first 40- 50 feet, and I can't hit full throttle until 40 MPH if I want traction.

[Mike M]

I received my 3500 PI converter and will install it next week. I am also sending out 2 rims to get widened next week as well. With my 4:10s and the latest tune I have just received, I will be hitting the track next Friday. I am at 9psi with stock exhaust. The weather is I hope going to be around 80ish here in AZ.

Any guesses to what it will run???????????????????

Any guesses to what it will run???????????????????That depends on whether or not you have the widened rims yet, along with drag radials. If you go to the track with stock tires, then forget about it. Most of your passes will likely be in the 13's with maybe one run that you might get lucky enough to pull out of your hat, that might get you in the 12's.

However, if you have the drag radials by then, you'll definately be in the 12's for most of your runs. My guess is high 12's. But that's if you're running 93 octane pump gas like I do. if you have a race gas tune, and will be running 100 octane, then along with the drag radials I'm sure you'll be in the mid 12's, and perhaps even the low 12's.

[BillyGman]

Wow those are great times for a N/A Marauder, as well as the S/C times...

Good work in both aspects :coolman: :cool:Keep in mind that the N/A times were done in 38 degree temperature, and the S/Ced times were done in 50 degree weather. In 70 degrees, my car was turning 12.2 ET's S/Ced, and was capable of 13.7's when modified N/A.

[Bradley G]

I'll guess 12.7

Who ever guesses the closest should be able to win something...hmmmm lets get money involved.
I will make a run tonight with 100 octane and stock tires and stock converter.
By next Friday assuming my rims get back in time I will do another run with 100 octane, Nittos and a 3500 converter.
We will have to have 2 seperate guesses, the closest guess will win gold, diamonds, yacht and an Ipod and a George Foreman grill. :-)

[GreekGod]

I thought I would remind or inform that 14.7" mercury is sea-level air pressure and doubling that to 29.4" with a supercharger has the effect of doubling the displacement of the MM 281" engine to 562", less frictional and heat losses from compression. At least that's my understanding of the general result of pushing twice as much air into an engine than it gets without a supercharger. So in simple terms, depending on the boost level, we can make our little 4.6 liter/281 cu. in. engine seem like a 500 cubic inch big-block with a supercharger. Maybe someone will correct me if my figures or generalisations are wrong. ;)

Just wondering where you plan to run on friday ? I would like to join you . I havent run my car yet ,I was waiting for better weather.

I cannot honestly say that my car moves like it has a 500+ cubic inch engine under the hood. A 383 cube engine yes. And one hairy 383 at that!

Mike,

Which strip are you going to?

What tires will you have on the car?

I'll take a guess after I know those two things !

Stock tires you will manage to get about 12.60's.

With the Nittos, all things being equal you will dip to about 12.20's.

The stock tires will not allow you to get the beast going soon enough to really get the 60' down.. an thus the higher ETs.

This also assumes you are running in Phoenix at one of the lower elevation tracks. If you are going to run in Tucson add about .3 on my estimations.

There.. I have my guess in.... I am shooting for an IPOD !

[jdando]

After consulting the magic 8-ball......

12.95-13.6 range

with the best run of the night/day














12.85

I would prefer the George Forman Grill

Hey, I am right there with BillyGman. The MM is a monster. Try driving one with the Naake system. RAILS

I nominate you as the poster child for the Trilogy Marauder.LOL.....well, after 18 months, and 24,000 miles after my Trilogy supercharger installation, I'm so pleased with it, that I fully accept the nomination. ;) This car is the fastest car I've ever driven on the street on a daily basis for transportation. While at the same time, it's so well behaved in traffic, and at less than half throttle, it's just like it was from the factory, with the exception of the louder exhaust I have on it.

Less than half throttle = docile, and perfect driveability even in the snow!!

Half throttle & more = rice eater,Camaro SS eater & Vette eater all in one

It's the best of both worlds!!!! I LUV driving this thing!!!

Coil-over adjustable shocks aka QA1. Combined with front & rear sway bar upgrades and the Metco control arms & watts link makes an MM handle like a sports car instead of a 2 ton tank. :coolman:

Got to the track (SpeedWorld) after being in bumper to bumper traffic for over an hour. Filled my empty tank with 16 gallons of 108 octane unleaded, $6 something a gallon (ouch). After a fiasco of broken cars and a terribly run track I got to make one pass. I heated my worn KDW tires and left very easily but still ended up spinning. My E.T. was 13.52 at 103.17 MPH.
Next week time permiting my 3500 PI converter will be installed and my Nittos will be on.

Yep, just as I thought......all that power is a waste at the dragstrip with standard radials. You just cannot put much more than about 300-325 HP to the wheels at the dragstrip with a Marauder having the factory stock tires, or similar tires. Atleast not on a consistent basis. Drag radials aren't just sales hype. With a 12 second car or faster, there's a genuine need for them.
