Anyone know how to make my 99 v6 fast?

250hp in an Explorer still = sloooooow

 

[derek_redneck91]

How are those numbers unrealistic? I've seen several websites that say either 210hp or 215hp for the stock SOHC explorer. Intake numbers dyno'd at 10-13hp. Exhaust upgrades have been proven to add at least 10hp or more over stock on any vehicle. And the tuner packs I have looked up (including sct) are rated at about 15hp. And 250hp is a hell of a lot better than 160hp of the OHV! And if you are refferring to the numbers of the 5.0L HO please refer to this website.

I checked around on other websites and got the same numbers for the HO
I'm not trying to be butthurt here, and I don't want to start some blood bath for no reason, so if you can prove me wrong, please do so and I'll shaddup.

Your numbers are WAAAAAYYYY OFF.most sohc put out about 160hp to the ground the 210hp is at fly wheel.you can subtract about 20% from all those numbers you posted and be closer to the real hp.noone needs to prove you wrong,just use the search button at the top of the page and your prove yourself wrong"sohc dyno"

How much did the tuner cost? I'm thinking of getting a tuner pack and swiss cheese CAI with K&N Filter after I put a new 4.0 SOHC in my explorer. The current engine's timing components are done so I'm doing a swap following 2000StreetRod's thread. I already have a modified exhaust as you can see in the 4.0 exhaust thread found here. http://www.explorerforum.com/forums/showthread.php?t=192528

The SOHC has 215Hp stock. Add custom high flow exhaust to free up 10 ponies and you have the same hp as a H.O. 5.0L (about 225-230HP). Add CAI for another 10hp, and a tune for another 15+ and you are sitting right around 250hp! More power and better mileage! That extra 30+ hp is going to give you a serious gain in performance and you will be able to tool most tuners and other morons on the road!

If you really read or was following his threads then you would know your numbers are off

5.0 still has way more torque.

I think 10 hp from an intake is optimistic and at best you may get 7.5 sec 0-60 - maybe enough to kill a couple ricers, but still not fast.

 

[derek_redneck91]

JD4242, Very interesting. I think someone needs to update http://www.explorerforum.com/ntrprize/spec1999.htm to say that that is flywheel power.
Feels like these things have a fair amount of power compared to the ohv. Oh well. Thank you for showing me that.

Masospaghetti - yeah I know, torque numbers are huge with the 5.0 ho

 

[FIND]

The SOHC does have a fair bit more power than an OHV 4.0 has, and the AWD can make a 5.0 feel sluggish, but yeah... everything else that needs to be said has already been said.

Duster....

okay so my tuner was $320.00 u.s.d. and who ever thinks that a 4 door explorer v6 weighs 4600lbs, you have another thing coming. I work for waste management and everyday i park my explorer on the scale before i leave and its only 4000 lbs. And a 30 to 40 h.p. increase does make a diffrence in power and fuel economy i see it every day used to i got 325 miles out of a full tank now i get just over 400 out of a full tank.

Mine weights 4601 with me in it with my tires and two heavy 12" subs.im 247lbs and box is probably close to 80lbs so a stock ex should weight pretty less

And 30-40hp combined with right gears does make a difference when it to the rear wheels but the ex is more about tq not hp

Waste management huh? Is that another way of saying you work for the mob?

I get 400 miles out of a tank... you know these things have 20 gallon tanks... 325 miles for a full tank of gas is significantly less than they got when they were brand new... just saying. And sure 30-40 hp makes a difference, but you aint getting that from the mods they listed earlier. My 4 door xlt weighs 4560 with a full tank of gas, I've had it over a scale a few times at the elevator. Now, I know I have a V8, but they don't weigh 600 pounds more than a v6. Even still, I stand by my statement I made earlier, 250 hp in a non-aerodynamic SUV with soft suspension, a high center of gravity, a slushbox, power robbing transfer case, and 1000-1500 lbs on top of family sedans with almost that much power stock is slow. Hell, a 99 taurus had 200 horsepower at the crank from the factory, and someone in here thinks that they are going to dominate the tuners who are in even smaller, lighter cars with almost that much power stock, that have a better power to weight ratio than an Explorer ever will with a couple little bolt-ons?

You can make an Explorer fast, but bolting on exhaust, a tune and an air filter aint gonna do it for you.

okay so i have a 99 explorer 4dr i just ordered a sct sf3 flash programmer and put a 2.5 inch magnaflow exhaust in it today what else can i do to make my explorer run faster money is not a problem i just need ideas also im working with the 4.0 v6 so i really wanna make this thing run without using nitrous

How can you make it fast? is 0-60 in 7 seconds not fast enough for you? the 97-01 Explorer SOHC V6 is one of the fastest stock SUV's ever produced. my 97 XLT SOHC and 98 XLT SOHC did 0-60 in 7 seconds flat. Only mod i had was straight through exhaust on them dumping out before the rear wheels. my 99 XLT OHV that I have now is lethargic compared to the SOHC but it still has a ****load of torque off the line.

 

[FPGT24]

The SOHC does have a fair bit more power than an OHV 4.0 has, and the AWD can make a 5.0 feel sluggish, but yeah... everything else that needs to be said has already been said.

i wouldnt touch a 5.0L AWD Explorer with a ten foot pole. they are slow compared to the SOHC V6 and the AWD kills fuel economy. Now a 5.0L RWD only Explorer? now we are talking. I hope to get my hands on one of those soon.

 

[Runnin'OnEmpty]

Another low cost mod to gain more performance is
a rear gear swap. Changing a set of stock 3.55 gears
for a set of 4.10's will really wake up a relatively
heavy vehicle such as an Explorer.

The drawbacks would be a higher cruise RPM and
less MPG..... But you'd be able to dust off every
Greyhound bus and dump truck you encountered.

My 5.0 awd is just as fast as a 4.0... Yeah, the 2wd is faster, but not by much. Weight is the biggest problem here, you are fighting Newton's second law a lot harder than you are fighting mechanical efficiency. Also, I have been getting a hair better than 20mpg on the highway in my 5.0 AWD, so I don't know why you think AWD kills gas mileage. Even the EPA didn't see a big difference in fuel economy between the V6 4wd and V8 AWD.

As to your other post, I think you are looking at the minutes hand, not the seconds hand. A 2wd 5.0 doesn't go 0-60 in 7 seconds, nor does a 4.0 SOHC. Maybe 8 seconds, but 7 flat? That just aint happening without a lot of power adders and a lot less weight. IIRC, an SOHC Ford Explorer was supposed to go 0-60 in 8.3 seconds according to all the guys who actually know what they are doing, like car and driver and those types of auto reviewers.

One of the fastest stock SUV ever produced? No. Explorers were heavier than some SUVs in its class, and just about everyone made the same amount of power. Chevy S-10 Blazer? Weighed less. Less powerful engine, but not that much. Cherokees also weighed a lot less than an Explorer, nearly 1000 lbs less, and they made only a couple horsepower less than the S-10 Blazers. I do believe the Explorer beat those two in reliability, comfort and build quality FWIW.

Your OHV makes a lot of torque off the line? Interesting, since a stock SOHC produces 254 ft-lbs of torque and the OHV gets 225 ft-lbs, and these are put inside of vehicles that are as heavy or heavier than full sized pickups of the same year that have bigger engines. Those torque figures aren't really that impressive...

I mean, I read your posts, and I see you making a lot of statements that... Well, I don't know where you came up with them. If you had done any reading or research, you would know they weren't true.

I don't know why people try and convince themselves that an Explorer is something it isn't. These are mid-sized SUVs. They are bigger than minivans with half the cargo room, but they can leave the pavement without any worries. If you want to make them fast, they need a lot of work, and even then, you are still fighting the fact that you are taking a huge brick and trying to motivate it to leave the line. If you want fast, get a Mustang. Hell, my old escort was making well north of 200 horsepower, and that was in a vehicle that was less than HALF the weight of these Explorers.

Or go to 4.56's like I did on basically stock sized tires and it REALLY wakes it up. I like it!

 

[OffTrac]

Making an Explorer fast is like making a Focus an off road vehicle. Sure, it can be done but there's two big questions to answer for either of those projects.
1.) How much money do you have?
2.) What's the point?

 

[Sedition]

Well if money is not a problem then I suggest that you go to some performance shop with hot cars parked out the front and ask for a twin turbo system.
