Next 4.7 Mod: E-Fan or Headers???

redram2007 · Sep 29, 2012

Right now im in the process of getting my 08 intake manifold ready to install just waiting on adapters and 70mm tb. I cant decide which would be the best mod to go with next as they are pretty close to the same price. Im looking at the gibson shorty headers only bc thats about all i can find for an 07 4.7. would really love to get some pacesetter long tube but cant find em, or i can go with the flex a lite 183 e-fan. The only downside to the headers is that the tubes are only 1.5" was hoping to get at least 1.75+. Anyway questions, concerns, or comments.

Which of those offer the highest performance gains??? They both sound sweet though, I'd love to do headers

redram2007 · Sep 30, 2012

Im not too sure ive read some reviews on the headers and a lot of people wasnt too impressed and some were. ive only heard good things about the e fan but i would really like to get all i can out of the engine.

Get a Taurus fan and you'll save over 150 bucks

redram2007 · Sep 30, 2012

Really!! Any certain year?

Catchin Zs · Sep 30, 2012

93-98 I think?? Any junkyard should have a ton of them. The Mark VIII fan works as well. Gonna try to toss one under my hood here soon. http://www.ramforum.com/f76/efan-diy-3455/

what about a relay or fan speed controller. I mean i could wire it up direct to a toggle switch but really dont wanna do that

Catchin Zs · Sep 30, 2012

Not sure about the relay. Probably a really heavy duty one. Here's the best controllers you can buy Relay Controllers and Accessories

I have never been a big fan of Gibson headers myself, so IMO I would not go that route. You can do the taurus fan if you want to make mounting brackets and buy your own controller. The Flexalite kits are nice because they are complete kits that are ready to install. They include all mounting brackets, wiring accessories, and the adjustable temp controller so that you dont have to piece your kit together.

Do you offer any group buys through any of the forums?

Hemi450hp · Sep 30, 2012

There are times when I will be able to host group buys, but I need to see what kind of interest there is in the items at the time. Electric fans havent really been a hot topic lately on any of the boards.

redram2007 · Sep 30, 2012

What is a hot topic (item) right now?

Probably the Moe's Ported throttle body!

redram2007 · Sep 30, 2012

It wont work on my 4.7 though but thanks

Catchin Zs · Sep 30, 2012

Do you have a programmer? That will help out with power and mpg

redram2007 · Sep 30, 2012

yessir i have a superchips vivid

redram2007 · Sep 30, 2012

Considering im getting the e fan and have a sc vivid and the option to control my fan speeds. do i need a 180 t-stat or will i be fine with what i have 195 or at least thats what i think i have

redram2007 · Sep 30, 2012

Lastly what about coolant type. i have the orange type do i need to buy some from the dealership or what?

Catchin Zs · Sep 30, 2012

Pretty sure the stock tstat is a 203? Someone chime in if I'm wrong, but I think that's the case. 180 just helps keep it cooler. Can't say I've been able to tell a difference from it other than a cooler engine. Good enough for me though. Only downside is in the winter, you're heat either won't be as warm or will take a lot longer to get it as toasty as you want lol. And I've always run the 50/50 prediluted stuff from autozone and it's worked fine.

redram2007 · Sep 30, 2012

i looked on autozone and a direct replacement for the 4.7 is a 195 so i think ill be good.
