I need to regain some of the power that the truck had before I put the wheels on,(which wasnt much but I still need it back) and hopefully gain a little more. So, what are the top 5 things that I can do to gain power. And, if you so happen to know the prices that would be great.

 

1. Tuner
2. UD pulleys
3. E-fan
4. Throttle body mod or Escape TB
5. Cold air intake

 

1. XCalibrator 2 tuner (XCalibrator from Underdog Performance )
2. Underdrive pulleys ( Pulleys from Underdog Performance
3. roller rockers (roller rockers from Underdog Performance
4. efan (efan from Jusnes Modified)
5. complete exhaust (headers, and cat-back) (JBA headers from Underdog Performance) (JBA cat-back from Underdog Performance)

 

Thanks!

 

on my 4.0 4x4 i went to the track and ran a 16.3 stock. After installing 33's and then installing underdrive pulley, catback, K&N intake- I went to the track and ran a 16.3. Those 3 basically brought me back to even with no regearing. I since added an e-fan and tuner so i should be slightly ahead.

On the 3.0, Maurice pretty much nailed it. My buddy here ran a 16 flat in his 3.0 single cab (who said the 3.0's were dogs? he beat my stock times on the 4.0). he has K&N intake, roller rockers, 3 piece underdrive pulley, muffler. he left the tuner at home. It was on the mileage program. he would've hit 15.xx if he had brought it.

 

intake. exhaust. tuner. find a whipple somewhere.

 

Would a high flow air filter give similar results to a full intake? I'm getting the pullies next month and maybe an amsoil.

 

I'm not sure Kyle. A hi-po filter change wouldn't hurt. thats for sure.

I forgot to mention, we did a throttle body half shaft on the 3.0 i mentioned above. free mod.

 

Thanks. Is there a how-to on that mod? oh and since your here, the crank pulleys give you better mpgs right?

TB how to above.

pulley-you should gain 8+ hp 11+ torque. On the mileage, it seems to be a solid 1 or more based on my trucks. Say you get 17s, sometimes 18 mpg depending on driving. After the pulley it turned into 19 always. If that makes sense.

 

Thanks Wayne!

 

On that throttle body, someone flow tested the maf sensor and throttle body on a ranger 3.0. It turned out the throttle body was a bigger restriction on the plumbing than the maf. it's been a while but it has stuck in my head.

 

so with doing a 60MM TB off of an escape, under drive pulleys, e-fan, and roller rockers, how much do you think you could pick up power wise? (est) All of these mods I will be doing within the next 8-10 weeks and I want to make sure there worth it before making the installs....sorry for robbing the post!!

 

So that E-fan from Jusnes is a complete bolt in part right? BC I've been wanting to do an E-fan but haven't found a bolt in kit yet.

 

1. Tuner
2. Underdrive pulleys
3. E-fan
4. Throttle body mod or Escape TB
5. Cold air intake and exhaust

 

What does an e-fan do to give you more power?

- never mind... searched

 

kind of. you have to wire it so it works right

 

How difficult is it to install a underdrive pully kit on a 4.0 SOHC.

 

i'm curious about this also

 

2-3 hours and some specialty tools required. the tools can be borrowed from a parts store. Here's a write up:

the hardest part is breaking the nut loose. It's tuff. If you have a manual you can put it in gear to keep it from turning.

 

or you could regear.

 

How much Hp and Tq will you gain from a set of headers?

 

Depends.... There was a guy on RPS that did it and said he didn't gain much, but it moved his torque curve lower in the RPM's and made the curve flatter if I remember correctly....

 

This is a really good thread for the 3.0L ... Thx for the info guys..

I bought my underdrive pulley from Wayne (graniteguy)
