TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

So i was having a P0304 code popping up when i got into boost then turned into p0300. so figured it was either a spark plug or coil pack. decided to replace all spark plugs and also the coil pack on cylinder 4.

All plugs were gapped between .045" to .055" the manual for the supercharger states .032" below is pretty much what all the spark plugs looked like



also i cleaned up the supercharger and adjusted the boost valve on it. everything is better and it feels like it runs better and pulls better when in boost now.

 

Interesting.... mine looked about the same and I didn't have a single code.

 

i think the gap was what was the issue

 

Got boost?

Pennsylvania


New Hampshire

 

How many miles did you have on the plugs? If you were ov 90k, hell even 50k you shoulda swapped them.

 

Picked up your new build? Sas, 40’s, and tt LS swap? Awesome

 

i was at about 30k. and i did swap in new plugs. put new plugs in back when i installed the new engine at 49k miles. sitting at 79k now. had planned to swap them at 90k but didnt quite make it there

 

I always thought it was bad practice to adjust the gap on iridium plugs? I guess it’s okay if your extra careful

 

all mine came gapped at .025" so put them at spec for what the install manual calls for

 

Normally yes, unless you have a good method and a fine delicate hand in doing so.

That's odd. Most of them usually come in at .035-.040 I wonder if someone dropped the plugs box at some point prior to you getting it. Even though they come with their plastic sleeve to protect the plugs anything is possible.

 

all 8 of them? doubt they were dropped. and yeah, i bought 8. dont ask why. bought 2 4 plug boxes.

 

now just a box of 4 for next change.

 

Yup. Was thinking that when I was cleaning up

 

Why would you buy 8? Lol. You told me not to ask, so naturally I'll do the opposite.

And yes it is possible to drop all 8. If you drop both boxes which are in a package when opening them. The same slamming motion is enough to distribute drop force across all of them.

 

Got them from rock auto and got two boxes of four. Plus I was gonna order some for my GX also but didn’t. And yes I did install the correct ones in to the taco.

 

I mean, that’s really the only logical thing to do.

 

Just pulled up to the exhaust shop, and what are the odds that they were cutting the OEM muffler off a 2019 RAM as I got there.

If I’m wanting to keep exhaust note minimal, with increased flow over factory, this’ll do the trick? It’s either this or a large body magnaflow. Muffler guy is saying he thinks the Dodge one may be too restrictive. 2.85” pulley, aFe intake with TRD SC tune currently. Plan on HPT down the road but power is really not a priority currently. Have about an hour to decide. Plan is 2.5” y-pipe to 3” v-band then 3” the rest of the way back with the RAM or Magnaflow muf, dumping over the axle.

 

That’s the one. It is 3” in and out for a truck designed stock at around 400hp. I’ve got mine in the garage still until I can mock it up with my JFR Y all at once.

 

Fuck it I’m gonna give it a shot. Worst case I swap it out with a magna down the road but I think I’ll be happy with it.

 

what's the diameter of that muffler? wonder if i can even fit one with my trac bar in.
