Well, in that case, POWER! lol. Would exhaust and an intake help gas mileage much? I guess im just hoping to keep it about 21-22 highway. Do you think thats still possible? Im almost set on the 4.10s whether or not i get good gas mileage unless its horrible. My old econoline got about 9 city, 13 highway, so i do know whats really rediculously bad.

I really don't see how any power adding modification claims to help gas mileage. More air needs more fuel so you don't run lean. More fuel + air = more power. More fuel being used means less miles per gallon. Honestly, in the end I don't think you'll see such a dramatic drop in gas mileage to care that much. Unless you're driving 200+ miles a day, then I think something with a 4cyl engine would be much better for a daily driver.

ok someone tell me whats the exact hp/tq of a stock 99-04 3.8 ?

99-00 = 190hp at the flywheel and I think 220 ft/lbs of tq
01-04 = 193hp at the flywheel and either 220 or 225 ft/lbs of tq

Torque numbers may be a bit off, people usually just ask for the horsepower so I haven't gotten to answer the torque question in quite a while :sorry
Edit: Figure in drivetrain loss if you want numbers to the wheels. Manual = 15% loss and auto = 20% loss.

Roughly. You have to figure in loss with age and gains with any mods you've done. Car companies like to show us the nice numbers the cars make at the flywheel because they're more impressive than what the car makes at the wheels.

lol so that nice 300hp in 2011 will bottom out :p 240ish ? and the 5.0 .... wow damn 320ish I hope thats not true :'(

well **** I was thinking that stock rwhp was 193 and that with CIA and Tune i might be near 200 :( guess not ****

The 2011 5.0 dynoed at 376 hp I believe. The hp that ford told us was a little low.

A dyno as you think of it is whp. They have engine dynos which is probably what the first issued numbers from Ford came from. They hook the engine up outside of the car, connecting tubes to the headers. Horsepower tv on Spike, yessir.

Ok, one more question. I went to the shop that i normally go to for advice and other problems. They do a good job for a good price and they told me that since they dont have a dyno for tuning or anything like that, that i could probably do just as good of a job on the install as they could, if i researched it carefully and spent enough time making sure i was doing it right. Does this sound correct?

You're talking about installing the gears, right? I wouldn't let them touch the gears. There's no dyno tuning needed for new gears. Your handheld tuner has an "adjust options" section before it loads the tune to your computer. One option is "gear ratio" and that's all you need to change once they're in. The install doesn't require your car to be within 3 states of a dyno.

Installing them yourself isn't something I would recommend unless you really trust yourself. Things have to be lined up very very precisely or you'll end up with gear whine and, trust me, it's annoying.

Hmm... the closest thing that ive ever done to gears in a car is working with/shimming the gearbox in high end airsoft guns. So do you think it would be easier to put in a mild cam? if it is, maybe i could convince my parents to let me do that instead.
 
#37 ·
Um. If you don't know where to start with that either I wouldn't do it yourself if this is your only means of transport and you don't have money to fix it if/when it breaks.

I kind of built my way up to doing the cam install myself. Started with a CAI, then long tubes, springs and shock/struts, then the windstar. This gave me enough confidence to where I figured I could install the cam myself (I also gave myself a whole week to do it). I wouldn't tackle a cam install if you haven't gotten you're feet wet with anything else before. Thats just me though. If you do decide to try and install one, do A LOT, I MEAN A LOT of research about it beforehand and have someone there that knows what they're doing.

Cai, full exhaust(with long tubes) UDP and a good tune should get you to 200ish at the wheels, and learn a bit about working on your car...

Ok, i guess i realy dont want to do something expensive and screw it up. I think ill just do simpler bolt ons then, the power wont be there, but it would be better than wasting money on something because i dont have enough experience.
So...

CAI
Full Exhaust
UDP
Tuner Chip
Subframe Connectors
Rear Sway Bar
3 foot tall spoiler (just kidding)
Windstar intake (eventually)
Umm... anything else that i forgot?
