HO cams are the best upgrade and I just so happen to have brand new set....very rare.

 

where did you buy your cams for your 4.7 thank you

 

What's the cost on those? (Looking for cost/effectiveness for the first few...)

 

how much scott

 

intake, exhaust, superchips tuner........

that might get you 20

 

Buy the cams....

 

I have a K&N intake, magnaflow muffler but I doubt you will see 20HP from them alone, you might get 20-25 if you do those mods and a Superchip. The intake and exhaust make it sound faster so it seems faster to me and most people who see it. =D I might not be the fastest car out there but my 05 4.7 sounds badass!

 

x2. Mine deff sounds like it has more then a bolt on 20hp.

 

Anyone want to elaborate on the HO (High output? Horizontally opposed? Heavily Oiled ?) Cams? I will be looking for some performance upgrades soon also.

 

high output

intake, exhaust, and a way to tune.. cams are also a good choice, along with a throttle body, colder T stat, torque converter, gears, heads, oh sorry..... I got carried away LOL

 

SCJeep, thanks! Looking at your list of mods gave me a few good ideas.

^^^^theres a couple forums that block JeepGarage links...so we reciprocate with them. Sorry

 

Yes add a magnaflow I just put a 8x5x14 on mine sounds so nice now. As far as performance maybe few HP.

Sent from my Evo 4G

 

Mopar H.O cams and valve springs will be a nice upgrade. 25RWHP gained. I had them in my 07 4.7 and it really woke the truck up. Definatley noticed more power with the cams when i had the superchips tune installed.

 

What super chip you us?

 

Scott, I'll give you internal body parts (Lung, Heart etc.) for those cams!

 

The cams can be found dirt cheap from Henson.

If you dont want to tear into the motor, a intake, 3" exhaust w/ high flow muffler of your choice, and a bigger TB of your brand preference is a solid start, and well within the PCM's ability to understand. The 2003-2007 PCMs arent as forgiving to modifications as the earlier models are.

 

^^^^^yeah...over $300 cheap...plus the springs. He's only asking $200 for them...which is cheap IMO.

 

going to piggy back a little... what is the commonly accepted "best" intake for the WK 4.7 right now?

mwoody:d

 

K&N 63 or 77 series. The ones that remove the air box thats mounted to the TB. 90% of the other intakes dont do that.

 

but i dont want an oiled filter, right? i want a dry charger?

 

You could go back and forth on the oiled or dry filters all day and into tomorrow. Ive used both on different vehicles...not really noticed any sorts of differences.

 

I'm happy with my AFE intake, doesn't delete the air resonator but a little bit of tubing could do that. Couple that with a ported and polished TB, muffler, and you'll notice a big difference.

 

the best MOD hands down I did to my previous 2006 4.7 was the cams and tune to go with it.....

 

Are there head & cam options that will benefit the genII 4.7?

 

Yeah, cams are tough to find but it can be done.

 

oh yes...but they will have to be custom made/machined
