99 5.0 Upgrades

[DarkFox1]

its not, I'm trying to figure out what sports car you have pushing your trucks when you accelerate. I'm 98% convinced that my truck IS in top form, aside from a more than often tranny wiggle, and yall seem to think that I'm wrong. it all adds up.. the numbers cannot lie.

peak HP came about at about 4000 rpm.. when accelerating 0-60 flat out to get the optimum time I get 5500 rpm before it leaves 1st gear, by the time its up to 60 its at the bottom of 3rd and at a good 2k rpm at cruising.

What numbers? You do not have any track or even G tech numbers and a single Dyno. Have you actually weighed your truck?

 

[DarkFox1]

no where to do it.. I calculated vehicle weight based on the stock weight of a '96 4dr with the 5.0 and added the weighs of each of the components I have on the truck.

there are no tracks close enough to test my time.. and even at that I doubt they would let me do it.. not to mention being SEVERLEY humiliated when there are spectators of my pathetic time

How in the heck are you guys turning 8's in your X? I actually did a few things to my ride tonight that made a huge difference. When I did my 0-60, it was 10.3. All of my tires were 23 PSI. I filled them to 34 and retested it. I ran a 9.8 Plus, I was one man shy in the back. I checked my throttle cable and it was fine. I ordered a programmer and Cold Air Intake for it today. Hell, I should'a did the head work for all that cash!

DarkFox, I understand the frustration. I don't understand it either. I'm not sure what you mean by a "tranny wiggle". But I know that the timing between shifts is too damn long. That's where I hope the programmer steps it up.

forget us running 8's, how the hell are you in the 10's??? your slower than my 94' ohv V6 with 3.27 gears.
To get 8's all I do is floor it and bingo - 8 seconds to 60 and 16.2 through the quarter at 85mph.

I have no idea whats wrong with your guys trucks as you are the only ones with this problem.

With 5 guys in the 5.0 Mounty I still turn in faster times than you guys.

Look at mags times you'll see an average of 8.2-8.4 seconds for the 5.0 Explorer, since I can pull 8 seconds flat to 8.2 their pretty accurate.

No idea dude. At normal cruzin speed I'll hammer it and it's a totally different SUV. It responds very well on the top end. It's just my 0-60 time that sucks. I have a very difficult time beleiving that I got a "lemon". My X runs very well, great gas mileage, no problems with it what so ever. I'm hopeing to get some pics up soon. Then people can see what I'm working with.

"tranny wiggle" was a nice way of saying "the 4r70W SUCKS!" its a horriblly unreliable transmission.. I have 70k on my truck and I am in need of a 3rd transmission.

when I bumped my tire pressure from 22-32 I took 2 seconds off my time.. but its still only a 12.

as I said I guestimted my truck weight at 4800 pounds.. giving me a 20 second-ish 1/4 a 12 second-ish 1/8th and a 60mph 1/8th.. so it adds up.

what happens when your lsd fails? more and more often latley.. when I press the gas.. I get a feeling like I'm spinning tires.. yet... I know I'm not spinning.. the trucks just not moving. a friend of mine told me the limited slip wasn't working cs I only spun 1 tire when I climbed the dirt part of my driveway

 

[SaleenEXP]

the 4r70w trans is basically one of the best built transmissions in the world. There are a lot of guys on here that are a hell of a lot harder on their trucks then you are and they have well above 100,000 miles with no problem at all with their trans. My friends just sold his 5.0 Explorer a few months ago, he had 155,000 miles on it, off-roaded, raced, towed almost every other day and was still on the original trans with no slipping or anything. Our 97' was turned in with like 80,000 miles and not one problem and our 00' 5.0 has no problems.

Tonight, I'll borrow my neighbors g-tec and I record my times with 4 or 5 guys in the truck, I guarentee you it'll be a few seconds faster than your times.

4800lbs, you must be one big ass guy, and have cement filled in your truck

 

[DarkFox1]

the truck weighs 4000 pounds empty stock. I aded the weight of me, my system, my neon, my grille guard, my exhaust, my taillight guards, my rims and thats what came out.

so what happens when the stock limited slip goes out? it just becomes an open diff?

 

[SaleenEXP]

The heaviest part of any system is just the box and subs almost nothing else weighs alot. Grill guards are not that heavy, I can hold my friends huge gaurd for his Land Cruiser with no prob (50 -80lbs at the most) otherwise your front end would start to sag and handle sloppy. Aftermarket exhaust is light than heavy ass stock system. The stock rims are very heavy, and you probably saved weight on them with yours. If not, the most you'll gain with those wheels is 3lbs or so per wheel. Everything else doesn't even matter.

If you weigh around 200lbs, with all the rest of the stuff your truck would only weigh around 4300-4400lbs at the most.

As for the limited slip, not really sure, I would guess that if something went wrong it might act like an open diff but I'm not sure, never had that problem

I had a friend with a Denali, one very heavy grill guard that was twice the size of yours, 20" rims, a heavy ass stereo consisting of a custom box with 2 twelves on top and and one 18" on the bottom side. A bunch of other stuff, and you could not tell a difference from stock, only after he got rid of the rims and added a huge lift and suspension ect. for off-roading and big ass tires did you notice a difference but that was becasue he also still had the stock gears in both axles.

2 questions for you fox.

1.If you're soooooo concerned with performance, why the hell do you have so much heavy stuff in and on your truck? Ditch the brushguard for god's sake man.
2.Where does your statement about the 4R70W come from? So it's "horribly unreliable" because your POS broke? No one else's is unreliable, just yours. Quit making generalized comments.

 

[SaleenEXP]

yeh, try to take the guard off even though you don't have a big one, it might make a little difference. But actually everything else you have on your truck saved some weight, aftermarket rims are normally heavier than stock, with you 17's you probably saved a few pounds per wheel. As for everything else the tail lights, neons, system ect. thats not heavy or enough to make a difference on your times.

As for your trans, you said it was shifting sloppily right? If thats true, and it's slipping (which on a 4r70w you would be like the 1st person with this problem) that could make a difference on your times. Although I don't know if it would make a big enough difference to cause your truck to be slow.

 

[DarkFox1]

I'm not taking the guard off, it hides 2 scratches on my bumper from the previous guard, and I think it looks good..

the thing isn't painted steel like the stock guad on the land rover its polished stainless steel. it weighs probablly 200 pounds.

my stock rims were aluminum, my current rims are chrome plated aluminum, they're 15s, not 17s, I just wanted chrome.

jason I'm not trying to drag race people.. I have to drive my car every day. .and currently, its too slow to handle daily driving. it takes forever to do things and in tight situations that can really screw your commute over.

I have 69k almost 70k on my truck (its like 69,8 or 69,9 or something) and I'm on my 2nd transmission, and the way this one is acting, I'd say I'm almost ready for a 3rd.. theres no possible way this transsmission is one thats "the most reliabile in the world" I think you said earlier. with this kind of failure rate. Yal are probablly very easy on your trucks. I know I'm hard on mine, I dog it every day. I'm an aggresive driver, thats just the way it happens.

I described the transmission problems in an earlier post, or tried to... I told my friends I think my car is constipated lol

 

[Apten]

dark, after your first transmission failure, did the shop replace your radiator or install an inline filter? If not, you'd better get one of those ford inline filters monday. I have the part number if you need it.

Burnt up friction materials get stuck in the radiator when a transmission fails, and after you rebuilt the transmission that old friction material can get in your new clutches and eat them up fast, casuing repeat failure.

 

[DarkFox1]

hrmm, now theres something I haven't thought of at all.. they did a fluid flush when the transmission was replaced.. would that take care of it? they didn't install any filters or replace my radiator.... this much I know

 

[Apten]

nope, a fluid flush won't take care of it. Here's the part number for ford's filter kit they recommend after transmission repairs: XC3Z-7B155-AA.

it installs on the return transmission line from your radiator.

Darkfox - your gonna hate this but these are the times I got with 5 people in the Mounty. I'm 138, the others are, 135, 175, 184, 170, 165, thats over 950lbs of extra weight.
0-60 : 10.01 seconds
1/4 : 17.27 at 81.8 mph

these were on the new series of g-tec which is extremely accurate. So with all the all the extra weight, I still would smoke the shiz out of you.

You guys are the only ones that are having these problems with the 4r70w trans. There are guys on here that off-road all the time, pull heavy ass **** all the time, race ect. and they don't have any problems. I know abunch of guys that have 5.0 Explorers with well over 100,00 miles that tow all the time ect with no problems. my friends towed almost every single day with their 21ft Mastercraft to the lake to go skiing and he had over 150,000 miles on the 4r70w trans with not one problem ever.

And I'm hard as hell on the Mounty. I constantly flogg it every day, take it to the track a few times per month. And in the summertime when we go to our lakehouse I have to tow a 20ft jet boat, 2 Waverunners back and forth each week. And when we go own to our place in the keys I tow our 27ft Fountain back and forth with no problems. Plus I have the cruise set on 75mph the whole time or faster if I'm passing someone.

And this also shows that there is something wrong with your truck, I can be towing the 27ft Fountain going 75mph and if I have to pass some one it has no problem picking up speed to pass them by giving it a little throttle. Yet your truck barely goes with one person

 

[DarkFox1]

how far are you from augusta? hehe, I see you're in FL. it'd be great if you ever made a road trip.. and my truck was still being the foo, that you could stop by and take a look.. I know I'm not crazy.. I just know it.

I'm starting a project to try and troubleshoot with a video cam.. if I can.. I'll try and compile this into an mpeg when I'm done.

 

[SaleenEXP]

I'm from Boca Raton so it's a long ways to Augusta Don't think I'll be driving up there anytime soon. My cousins live in Marietta and happy town Peach-Tree City, don't know how close they are to Augusta.

Heh, when I told my friends I was going to record the time in the Mounty, they were like WTF? Thought it was a little weird but I had to explain to them that there was a guy on this forum whose Mounty is a dog in acceleration. Blah, Blah, Blah; they were like ooook!?.

I honestly cannot figure out what would be wrong with your truck. It sounds like your trans is slipping ec. but that wouldn't be enough to lower your times that drastically. And if you have to be at around 4000rpm to just get moving ect. something is definitley wrong becasue at about 2500rpm on my Mounty I'll pull away from everyone at a light and accelerate quickly up to speed. Above 3000rpm the truck just hauls azz.
