just wondering...

how fast would about 375hp get you? not in a quarter mile but say, salt flats or something of that nature

 

my l98 can do 140 easily. :-) it also depends on what kinda rear gears you have too.

 

Isn't there a governor on it?

 

Nope, no govenor, at least not that I know of. I've had my L98 up to 135 before and I didn't even have the gas pegged. I also have crappy 2.77's though too

 

Well let me tell ya, I am stationed in Germany and We have the all mighty Autobahn over here. For those of you that have not heard of the Autobahn, its a bunch of really smooth long, long sets of highways that cover Germany. Once you get on them its as fast as you can go. I have had "Lucy" my Camaro, pegged at 145 for a while. I still have the original gears in her and I have added the clear head light covers to the front. You really want the nose down when you are rolling like that for a few miles, you would never believe how well those things work. I also had to add some hood pins just to reinsure me that the little hood latch is gonna hold. I have modded the susp. also.
Anyways. 145 and I was still rollin, What really sux is I was still getting passed by the ocasional BMW or Audi "STATION WAGON".
Yup Germans were not playing when it comes to thier cars. They aint nothing on the go but once they get going....They Go.

 

I've had my 1987 iroc L98 up to 145+, dunno how fast exactly, the speedo ends at 145....

Man, I certainly HOPE so. My LB9 (305) will get the ol' T/A past 140 on the open road, no problem. If a L98 won't do that, there are a lot of owners who got screwed. That's why the cars came with "Z" speed rated tires....

 

Have you seen the new M-5?? 394hp 4.9l V-8...definitely SOMETHING on the go

 

Hey

U can get them goin pretty good , around 145mph. It all deepends on the gears. If u have 2.73 gears its not goin go as fast as it is with 4.10 gears. Its hard to get them higher then 145-150mph because of the overdrive gear. Because when u are in overdrive u cant floor the peddle. U can buy a part that goes somewhere and inables u to floor it in overdrive. I have had my 1985 LB9 to around 130mph with the tach at only 4000RPM so it could go faster. I also dont have the right speed rated tires to try goin faster. If u dont have the right speed rated tires dont exceed the limit. I blew on of mine at around 95mph. not cool. It wouldnt matter if u had 350HP. U would only go as fast as the rear end and componets could handle. It would only matters how fast u get to 140mph anyways RIGHT.....Somewhere I read that a camaro could beat a porsche for 0 to 140mph. I dunno if that is true but if it is thats awsome.

If you are talking about top end, 2.77's aren't crap. The higher the gear (numerically lower) the faster your top speed will be. If you want to achieve a high top speed you are better off with 2.77's than with let's say 3.45's.

Hes right! I have the 2.77's in my car and I had her up to 135 on the oklahoma highways, then I looked across the median and saw a state trooper lights on and everything barreling across the other side coming at me flat out! The last I saw of him was a dust cloud in the median as I got off at the nearest exit and took the back roads the rest of the way home!

 

Should do that easily. Both of my LB9's would top 140, so with 375hp you should be hitting somewhere around 160 or maybe 170 if youre lucky.

 

Hey iroc_cragg, that is a beautiful IROC! Nice silver, with the black touches make it look reaaal nice!

 

Yup, there is a guy I work with that just bought a brand new M5. Dark Blue with black and red leather interior, I think it ran him about 60k. Which is not bad compared to what his would cost in the states. he said he had the govenor removed and got it up to 310 k's. I will get a picture of it and post it next week....

 

Even the lowly LO3 with mod's.....140 mph and not topped out

 

hey sbd, where at in Oklahoma?, lol i hate it when they do that..turn around....damn lol i've did that the other day...to bad he wasnt after me lol oh well better safe than sorry

 

My L98 before any mods did 145+ had speedo down to or below the MPH label on it... Thats with 3.27 gears, and using OD at about 70% throttle. Just don't go to much throttle once you get to OD cause it will downshift... not a idea.

 

ChevalierSS and sbd4de3,

when I said I had crappy 2.77's I meant thats one of the reasons that I can top out high, is because I have those gears. I'd rather have some 3.42's or something, but 9 bolt parts are too expensive. Besides how often do you actually hit 120 mph+ anyways??

 

my 1998 ford crown vic police interceptor is governed to 130MPH. rumor is some of the 1999's had no speed limiter and topped out at a little over 140MPH.

think twice before you try to outrun a cruiser, they may well catch up to you. (especially if they radio ahead to one of their buddies)

 

mechanicalmehem

Sorry bud just saw your post, LOL!

I lived in Moore, and at the time I was driving from Norman back to Moore. Where do you live?

Steve

 

I hit 125 at the very top of fourth gear (o/d off) in my vette. Could probably hit 150 but common sense caught up before i could throw it into overdrive.......

 

By using the same increments on my 145 speedo and marking the gauge several points after 145,a friend and I hit about 165 and still pulling before I had to brake on an open stretch about 1 1/2 miles long.

 

Lol no prob, i know the busy feeling, i live north of Shawnee but i work in Midwest City, i'm all over OKC though so i'm just usually answer with central Oklahoma LOL anyways gotta go later

 

First, Crown Vic's suck! I've spoken to State Troopers here, they say anything over 80 is uncomfortable in them, and one told me that she was going 110 once and she felt it was downright dangerous. Another told me that he could drive his Caprice (LT-1) cruiser at 100mph, drink a cup of coffee, talk on the radio, eat a sandwich, and look at a map and the car would still go nice and straight. He said that with the Crown Vic you better be holding on with both hands.

Crown Vic over 140??? That is definitely a RUMOR! Ok, so it has a Mustang motor in it, and it sounds real nice, but it's a big heavy tank!!! I don't care if it will go 300mph, it doesn't have the handling to keep up with Camaros, Stangs, Vettes, etc.

Lastly, What business does a police officer have going 100+mph on the highway? He's causing as much danger of injury to himself and other innocent people as the jacka*s he's trying to catch. That is why they put radios in the cars. As far as getting to a call, if you travel 80mph instead of 100mph, how much longer is it going to take you to get there? I read a little thing once that went something like this: "No Job is so Important, and No Call is so Urgent that YOU Cannot take the Time to Arrive There Safely"

Amen

 

I have to disagree. A friend of mine and me were on a trip and I was watching his speedo hovering at the 170 mark. There was a car in the distance that appeared, and was keeping up. We figured it was a cop, and sure enough, it was. There were a few out here that we know for a fact were equipped with factory prepped 351's in them, and that car was one of them. My friend went over a rise and jammed on his brakes and was inbetween 2 trucks. The cop caught up, slammed on his brakes, slowed down, checked out the car (which looks like total crap, I guess he figured there was no way it was going that fast) and then took off. I've seen those things accelerate at 75MPH, and its slow. That car was not slow.

And I read what you said about the suspension. Either it was changed, the guy knew how to drive, or its not as bad as you think. I used to drive my parents 68 GP (which was a 4000 pound car, easy) well over 120 and it wasnt bad at all. And it was not by any means setup for cornering.

 

I'm only 36 MPH from the "200" mark with this "tub", and there's a lot more power left in the exhaust and intake as soon as I decide to spend the cash on it....



But we're wandering away from the topic....

 

What back roads join Oklahoma to Hawaii without getting all wet?

 

I couldn't get my stock L98 with 3.27 gears past 130mph without redlining ...or maybe I was going faster, I was kinda scared to glance at the speedo/tach

 

Yeah, the trick is to lift up at about 125 or 130 for it shift into OD, since stock 700-r4s won't shift at full throttle, then you got to go about 70% or so it won't downshift.

 

man!, that is just scary to think about, having to lift to get into OD, then what happens if you happen to go a little to far into and it downshifts? lol can we say fishtale? lol j/k anyway that would be a gut wrenching feeling but thatd be totally awsome, i've only been to like 120, and that happened to be in a scarrrrrrry car it was new but man it was all over the place, i've had my truck to 100+, (peg actually forces the needle to stop) man it handels cool for being as big as it is, but i think the cover helps too, i dunno anyway it is definitely a rush:lala:
:hail: adrenaline

 

That must be a typo. Ain't no way in this world a 351 powered Crown Vic is going to keep up with a car really going 170.

As far as the comments about the A'bahn in Germany...brings back many fond memories. I put over 100k miles combined on two Camaros ('84 H.O. and my current '90 IROC) over there.

 

375hp in our cars should net about 180mph. Add another 300hp and you can get to 200mph.

That is my goal.

 

Zephyr,

It really shouldn't take 600 HP to get to 200. If your car is not very clean, you'll need more power, but the frontal area on a ThirdGen is not that large. I'm fighting a few more square feet with a 'B' car, and unless my calculations are way off, it should only take 530 HP to break the 200 mark (525 will net 197 MPH).

Unless I get out the Sawzall and start a "reduction" program, I'm looking at a little more twist from the crankshaft. 600 HP would easily get you past 200 into a severe headwind.

 

Hey Vader,

well, that is pretty good to hear, I only need 550hp.

Last night some dude said said his friends dad got to 215mph in his Vette, he said the Vette had 375hp.
I said

 

Typo? No, no typo. I figured someone would respond with something like that. We figure the guy was doing somewhere around 155-160ish, was hard to tell. No doubt that car was not dropping off fast, he was keeping really good pace. Thats one of the reasons we slowed down, who the heck keeps up with you when you are going that fast?

I've worked on a few of the 351 vics that came around while I was at the dealer. I'm telling you, those cars were very quick, plenty of HP under the hood. The 302 versions were dogs, and the 4.6's... LOL! I think my 4-banger pickup could outrun one of those all loaded up with equipment.

 

Yeah, I actually made the mistake of mashing the pedal once in OD at 135 mph... the 5000+ rpms or so after it downshifted scared me a little bit. Probably a good idea to go buy those GM parts for trannie if you want to run that speed huh? hehe

 

Hmm somebody has a name almost like mine, cool!

I don't dare take my IROC over 130 cuz there's some things in the suspension that I have to work out yet. It gets a little shaky at the higher speeds.

I like your ride Vader, would love to see a Crown Vic try to keep up with that LOL!! In stock form, the Caprice cop cars were the same thing minus the nice rims and fat tires. Maybe they'll make a cop version of that Mercury Maurader thing, then MAYBE they'll be able to chase somebody. I truely believe that suspension and brakes are what you need to go fast. Thats why I won't take mine up to speed very much because the supsension has seen 151K with only new shocks and struts, and the K member (I think??) got messed up when the car was in an accident before I got it......One of the holes is elongated where the left A-Arm bolts on and I think it can move around some and it makes for interesting handling. Gotta get 1LE brakes too. Speed is not good if there's a) cars on the road around you, b) the suspension can't handle it, and c) the brakes can't stop it. Like I said before, nothing is important if you can't arrive there safely.

 

I think I really need to change my name on here. It doesn't really fit my car anymore.

 

1998-2002 crown vics weigh around 4000pounds unloaded, a few hundred pounds heavier than a stock f-body. Is a big heavy RWD car, but has a reasonably powerful mustang GT drivetrain. At some point in future, interceptors may get the 300HP DOHC engine from the mercury marauder. http://www.mercuryvehicles.com/vehicles/marauder

It appears as though most of the f-body owners here have never driven a 98+ police interceptor. It's got watts rear linkage, "v rated tires", true dual exhaust and physically huge dual piston brake calipers and rotors. Handles excellent at high speeds, but may have some wind noise if police lightbar, spotlight, or big antennas are installed. 130MPH top speed has been personally verified by a few members of http://www.crownvic.net

As for original topic of outrunning the cops, a 350TPI iroc may well have a little higher top speed than a vic. But don't forget that the police don't play fair. If they can't win a race, they call over the radio to their friends to join in the chase. They also have other dirty tricks like using a helicopter with body heat tracking, deploying stop sticks, and setting up roadblocks.
