Top speed

[TP Derrick D]

Hey for the cars with 4:10 gears what's your top speed N/A and SC'd? Do you have tranny work done?

[justbob]

? My speedo doesn't go that high.

Yes.


Of course, I probably don't count for this exam.

Before & after the trans work I can get the N/A MM up the R in Marauder on the speedo,But only for a short time with the crappy roads here.:eek:

[slickster]

most Ive done was 130. might do 160? ill never find out

[whitey]

N/A ive been around 140 with 4.10's.

[champ1173]

I've had my MM for about a year n a half now, and I've never taken it up to 100 yet. I know, I'm a wuss.

[MERCULES]

N /A 120, the passenger looked like he was gonna hurl so I lifted.

[jsignorelli]

At the SAAC weekend a few years ago, held at the VIR in Virginia, I was clocked at 156 in the straights. BUT.. I do have a 5.4 Liter stroker with gears, suspension, exhausts, etc.

I guess I should have added top speed before your rear gears start howling

[robertmoreno14]

I would encourage you to handle your mods in a safe and controlled environment. last thing we want is another marauder to die. but more importantly, we don't want to hear about someone getting hurt, especially from the forum. Thanks.

Didn't you just get a Marauder?

[robertmoreno14]

yeah, but I read on the post that people try top speeds out on the road which can be unsafe... plus I have been watching all the links that people put on here about marauders in wrecks and such. I just look out for my marauder peeps. no harm of course.

OK, back to the subject....for all the people that's not scared or worried about other stuff, what's your top speed with 4:10 gear, N/A or SC'd before the gears start whining.

[Zack]

Fastest I've ever been was 157 with a Vortech, 4:10's and stock engine.
Back in 2004 on the way to Seymour, IN.

[captain]

N/A...100 then she struggles. will do it,... but she does not like it.
Stock gears would climb up to 120 in a hurry then start to flatten out.

[gpfarrell]

I think the NA cars run out of engine at just over 140 no matter the gears. Of course the stock driveshaft is dangerous over 120, so the 140 is a moot point unless you change it. With 4.10s the driveshaft spins faster, so even 120 would be very damaging.

Boosted cars seem to be in the low 160s if everything is just right.

My wife is pretty so I've never tried.

[stevengerard]

on a track I pegged it but had no GPS etc. - I'm guessing @ 155+

120 came pretty quickly - 140 took forever it seemed, ran out of straight around what looked like 155 - 156 at quick glance

The posted speed limit in Michigan is 70 mph, I have never traveled faster than that, ever. Speed kills. I also wrap myself in bubble wrap so I don't slip in the shower, you can never be too careful.

[TP Derrick D]

OK, now we getting somewhere. I was asking because when I had the Marauder I totaled it was N/A, w/4:10's, stall converter and what I think was the J-mod done to the tranny because of the way it shifted and down shifted. It would chip tires when it shifted, those mods along with a chip it was pretty quick. I bought car like that. Anyway it would run to 140 before it pegged out but at about 135 it would start whining. On my current car I put the tranny from the totaled car in it along with the Eaton and it would run to 140 quicker and at 140 start whining. Then I had to have tranny rebuilt due to blowing seals out and since then I've lost all the top end like I had before. I'm thinking it has to be the tranny or maybe its not built like it was before.
I'm wondering if the 4:10s may be too high for the Eaton and may need to put 3:55s back in. Its fun to smoke em for 50+ feet from a dig tho!!!!

Glad I don't live in Michigan, Its 75 in Texas but that's just a suggestion to those that's scared or let you know a little old lady is rolling past you doing 90 so stay out the way. LOL

With 4.10 gears, custom tune and torque convert. I was chasing a 2011 Roush Mustang with Stage 2. I saw nothing but bumper the entire time, but I had a blast.

Hey, he had 100+ hp and 600 fewer lbs. on me. Well, a little more of a weight advantage if you count my fat ass. :D

Thanks for your contribution genius, get off your Mom's computer and go back to popping bubbles on your bubble wrap in the shower.

I'm offended by your cursing.

If I still lived with mom, I would have a lot more money. Thanks for the positive reply.

The safety issue has gone way past out of hand on this site. The OP asked a question, instead of taking his car out and finding out the top speed, he asked for actual information from those that have already done what he was curious about. He was acting responsible, and got several good replies, and several that weren't.

[fastblackmerc]

I been just south of 140... once. Was still going. Was running out of road.

The safety Nazi's need to calm down and perhaps worry about their own well being and stop poking their nose into everyone else's...

Although maybe over the top of late I think their intent is correct as they are more or less looking out for everyone's safety. Unfortunately the drunk rarely dies in a car accident but the people the drunk hits usually do, excess speed often kills more than the one driving.

Back to topic, most road courses I barely hit 125-130 before I need to brake into a corner - these things need a bit more room to slow down than most cars out on the track.

My car was still pulling at 150+ but as mentioned you can tell they are a heavy brick in the wind over 120mph

you alright with me, I got a Stang (see avatar), a '00 Lightning and a Eatonized Marauder so I like to get on down the road as if I got a long way to go and a short time to get there. But my Stang will outrun both of them easily.

[jwibbity]

Fastest I've been was about 130 on I-77 North, it was relatively no cars on the road so I just wanted to see how high it would go before the "vibrations" got more intense than I wanted

Eatons, 4.10s, All 3rd gear, stock driveshaft with HD U-joints...

I did 147in a stock Marauder on a closed highway with a cop trying to keep up with me. I pulled the cop car at 125. The police chief wanted to know what the car could do.

[Vortech347]

Had my 03' up to 140+ crusing through the desert by the salt flats. I was in a convoy of mustangs heading to an old runway for drag racing. The fox was broke so I took the merc.

The 04' I haven't been as crazy with. I've hit 120 a few times but I'll cruise at 100 when driving to Vegas or back out to the salt flats/wendover.

I've been thinking about running the 04' in the 130 club out at the salt flats. You get 1 mile from a stand to do it. My fox did it by the 1/2 mile. There was an LT1 Caprice out there that day and couldn't get past 125. If I ran the Merc out there since I have 4.10's I would likely need OD. According to gear math I would be past 6000rpm in 3rd to get 130. I know these engine's with mostly stock exhausts don't make much power there. Going full throttle into OD is a big no-no right? Salt is hard to go fast on. It has a parasitic drag.

That's an all out raceway down there. The most my stock engine can muster is a pathetic 135. I think these cars are governed from the factory unlike my beloved impala SS that goes far beyond that with no type of governor in place.

The factory tune is speed limited to 120mph. Most aftermarket tunes / tuner will remove the speed limit.

[TP Derrick D]

Thanks for all the input everyone, even the safety first stuff, although I ignore it. I found out my car is pretty much in the same area as other cars with similar mods. Its pretty much gonna top out 135-140 just with the Eaton its gonna get to the top out point a bit faster. There were a few exceptions that were posted such as a stock Marauder topping 145, I guess the 300 hp w/ 3:55 gears is a plus after all. I remember running past the 140 on the speedo of my 225hp '89 Mustang GT in 1989 damn thing just wouldn't stop. When I paid big $$ to have the Eaton done on MarTilda, my '03 black 300A Marauder I was hoping to just bury the needle so deep it was at least 150. My Marauder is the only one of my 3 cars that I haven't got there yet. I like to know and have the feeling that when that 300C or Chevy SS roll by I'm not intimidated by what they can do on top end. Although in 2013 I did show a 300C my tail lights on a top end run with my totaled Marauder but about 135 he either got scared or knew he wasn't gonna pass. I was glad he fell back since my gears was starting to sing. Although a lot of people don't know what a Marauder is, the ones that count, meaning the people that's into cars and automotive performance know what it is just as I know what cars/trucks each manufacture has to offer. Its those people that want to and likes to dust you and leave your Marauder feeling inferior. So yeah I've zoomed past a suggested speed limit a few times at least in my old age I don't as much as I used to...LOL!!:burnout:

[justbob]

I don't think my non aerodynamic brick could stay planted to the ground from what my engine, trans, and driveshaft could achieve.

Using a calculator which does not account for aerodynamics...


4R70 with the final gear of .70 & 4.10's - 186MPH

TR6060 with the final gear of .50 & 4.10's - 261 :eek:

[ctrlraven]

NA, 3500 stall, stock gears and stock DS did 144 mph.

On the dyno, the car did 149 mph in 3rd at around 5800-6000 rpms I believe.
Y58s0rYzifY

The stock DS with stock gears driveline critical speed is 127 which is why the stock limiter is set to that. With 4.10 gears it brings it down to about 108 mph.

I upgraded my DS to a MMC off a late 99/early 00 CPVI, weight difference was night and day between it and the stock MM DS. The weight on my stock DS was starting to peel off so it was a good thing I did change it.

Here is a really good article to read about driveline "critical" speed/resonate speed.

My wife is pretty so I've never tried.

Can you and others go a bid farther into details about the stock drive shaft? I was under the impression that an aluminum drive shaft was the best way to go. I have one in my Mustang also because it and 3:55 gears was one of the 1st 5 mods I did to it back in '97 along with several engine & headers with bigger exhaust mods. How is 120mph damaging and what drive shaft is the way to go for replacement?

[Shaijack]

I was reading the GPS on the speed. Thanks 71Cyclone I was hoping someone else did it too.
RED 130
Black 147
Blue 128 let off of it when the police noticed me.

[Marauder24]

140. I got 4.10 gears S/C

[MGDriver]

Will yet have to find out, I'm usually cruising at 100 mph on the Autobahn just fine but I won't try to get it up to top speed until spring, our roads are bad in the wet winter.

[Marauderjack]

Somewhere along the way I did 215 MPH....my GPS recorded it somewhere in South Georgia??:confused:

I do not remember ever exceeding the speed limit by more than 145 MPH!!:eek:

Stock drive shaft back then too....must have been asleep or something??:rolleyes:

[hotford]

since Im from canada, metric.......
and our speedo are in KLMS and shows 220 KLM
I had the speedo pegged and the GPS recorded highest speed at 252 KLMS=157 mph
racing a AMG........this was in thrid gear pushing the car to 7K with 4:10, 305/45/18 tires on the rear...pretty much maxed out......

Congrats on the EURO RAUDER >> Has the propane conversion hurt performance ?:burnout:

[Windsor58]

I saw 155 in mine a few years back and it was still pulling pretty good. Just ran out of room. I think it would likely top out around 165 to 170. No whining. But mine has built transmission, metal matrix drive shaft, vortech and 4.10s.

[MGDriver]

Congrats on the EURO RAUDER >> Has the propane conversion hurt performance ?:burnout:
Yes you do notice it has less slightly less power when running on propane, would have to dyno it at one point to find out exactly but you can always switch back to regular gasoline to get the full performance. The system will automatically revert back to gasoline when you perform a kickdown so that you have the full performance available.

The car I drive for work is a 2010 Audi A5 3.0 TDI Quattro that will top out at 175 with the factory limiter removed which is set to 155. I can't honestly believe a Marauder would reach that sort of speed without major modifications but I'm happy to be proven wrong and will try this for myself at one point.

Thanks for the Info; Now back to Top end ,In the Delaware Maryland Virginia [Del Mar Va ] area there a 2 handful of marauders that are supercharged, Vortec Procharger Whipple and the Coveted Trillogy units that can clock 155 to 165 with no problem [yes modified ] most of these cars have updated suspension and brake components to handle the speed. There are a few N/A units that can knock on 150 mph "front door" as well :burnout:a few Marauder owners have lowered there rear end ratios to increase top end as well [ Mercedes secret for years ] Early generation [2005] to present Chargers have Mercedes type Trannys and low number rear ends as standard parts,, In more recent years Americans started playing with transmission and rear end ratios to get top end .

I get it - 12 years ago 300 horsepower was a bunch. Now you can rent a base Camaro with 305 and a V6.

Hey for the cars with 4:10 gears what's your top speed N/A and SC'd? Do you have tranny work done?

I only can get to 122 mph or so at the track and then need to stop before I run out of room. I'm not brave enough to go that fast anywhere else. :cool:

[djcrook73]

I know this thread is about 4.10 gears but with 4.30S and mild mods I hit 140 at about 5300 rpm in fourth. 120 Came up fast 140 took a bit longer. Felt like the size of car was outdoing the power at that point. I think it would have done 150 but probably at six grand and I think I would have scattered the bottom end trying. but winding it up to see what she could do was fun for sure.
