4.0L SuperCharger

1.5 to 2psi extra is common with the 2.85

 

yea I think im hitting 7psi with the pulley. before it was about 5

 

splitting hairs, but thats the urd supergrip 2.825

 

Nice setup. Looking to do the pump soon. Curious why not an aftermarket intake?

 

thats not my rig.

and I do have an afe stage 2 SI on mine.

 

gotcha. sweet. the truck currently has a k&n but im switching it out. I was debating between urd and afe but in the end I went with the urd and doing the maf calibrator as well.

 

had the urd..........
water flung up from rigs in front of me, and rain in general happend to work its way past the amsoil filter urd uses and hit my maf sensor.
Its not fun merging onto the freeway and haing your truck stumble and fall on its face for a second or two.
I was using the shield, but not the hydrophibic sock as that sock seems to cause a huge drop in performance imo.

Be careful in the rain if its the 1st time with the URD.

I do have a mesh grill tho.

 

You got me there. Won’t happen again...


Because I just ordered the 2.55” pulley.

 

congrats!
Im curious how your AFR changes

 

I have the UCON, so hopefully Scott will get it right where it needs to be.

I also have 61 lb injectors and the 7th injector kit coming.

I’m going to order the AFE Pro-Dry intake right now. I’m currently just running a drop in.

 

BTW...

Damn you OP. Opening this thread got me thinking about my Supercharger again

 

ur gunna hear the whine a lil more with the AFE stage 2 si.
much better song imho

 

Music to my ears.

 

I had one in my first x with no issues what so ever except once during a drive thru car wash water was sprayed directly and sucked in lol. it went into limp mode until I was able to evaporate all the water that passed thru. scary moment.

 

I used to think supercharger were too expensive. Then I paid a LOT for my truck and it came with it. I would do it again in a heartbeat. Superchargers make this truck amazing! I like my truck more than you should like a truck

 

Looking through old threads to find info on the NST pulley set for the supercharger, which are currently listed as "out of stock" on NST's web site. Do you have the supercharger pulley set, or just the set of crank-water-alternator pulleys? If you have the supercharger set, where did you buy them?

 

@Athlaos
I would guess that its the NST crank/h20/alt pulleys. I heard those are available again through NST and used sets pop up for sale once in a blue moon.

The NST supercharger set..... that's a rare unicorn. I haven't seen a set of those pop up for sale in 5+ years.

 

Go Ducks!!

 

I have the urd pulley. The Nst pulleys are just the water pump alternator and crank

 

Waste of money.
