nitrous for my little 4.7
 
My RCSB 4.7 running 14's is due for a nitrous setup in Jan. wondering you all's opinions are. Looking to run a 100 shot. I want more but idk how much this engine can handle. Also looking for plugs. And a custom HEMIFEVER tune for the nitrous.

nice lift!!! look at the zex wet setup..pretty safe for your setup..

You should be fine with a 100 shot. I try to run 1 grade better gas= 93 when spraying, 91 octane tune. I gap my plugs a bit closer, and run 1 range colder. Brisk makes nitrous specific plugs, but I just run either Champions or NGK's in my hemi. I never spray below 2800 and only at WOT. Should knock your times down a lot. Now go whoop on some EcoBoost and Tundra owners. Expect to hear a lot of whine when they lose to a lowly 4.7 Mopar.

Hey bud! I'll try to help you out with the plugs again. It's crazy how much of a PITA it has been trying to locate proper plugs for your application.

The 4.7L is a very strong engine, I'd look at whatever the hemi guys are spraying and would think that you'd be just as safe, and probably safer doing the same. The 4.7L uses a crank girdle, not individual main caps, and also the pistons I believe do not have the thin top ring land that is the common issue for the hemi.

Oh boy, here we go again lol...

I really wish I had access to a full catalog of plugs for a given manufacturer. I'll get back to searching...

Not sure what plugs you're referring to, got a part number specifically? And this is for the exhaust or intake side?

snrusnak 12-17-2012 09:06 PM

Well this is really weird.... it looks like bosch is no longer making one of the plugs for the 2008+ 4.7L.

Stock plugs are as follows:

Uppers.......FR8TE2
Lowers.......FR8T1332

The lowers(FR8T1332) are no longer found on bosch's website.

I have to search more. Basically, I think what you're going to end up wanting is an iridium plug one heat range colder than stock for the exhaust side(make sure projection and threads are same). And then a copper plug one heat range colder than stock for the intake side(make sure projection and threads are same).

Finding out specifically what those are is a little more difficult...

Darkknight3829 12-18-2012 11:07 AM

Can't I just replace the intake side? Or no?
