TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

quick sanity check - did you buy a NEW supercharger or a used one? If a used one, we may have more recommendations for you.

 

New

 

Assuming I never get to sea level is laughable

 

Nope. The 2.8 is a good balance for me. I spend enough time dragging a trailer offroad at seal level in places without cell coverage where reliability is critical that I didn't want to go smaller. I'm very aware of how these mods perform between sea level and 12,000ft and I think it's a good mix.

Also, even at 5,000ft where 75% of my driving is, it's like a different truck.

 

Took injectors in at lunch, he just called and said 3 were leaking but was able to clean them all out. 150$ for some peace of mind. Going to order my 2.8 pulley, and urd fuel pump kit next week. A new water pump for the engine and tracking down some bearings for all the supercharger idler pulleys and I will be ready to have a fun weekend in a few months.

 

I can dig up all the part #'s you need for the bearings. I recently did all the blower and engine bearings.

 

Oh god yes I would appreciate that. Ive got the engine idler bearings done but the blower specific bearings Im having a time locating.

 

Looks like this is your excuse to retrofit in a double bearing roller for your tensioner.

 

Maybe, want to put it in stockish form and adjust from there first.

 

@IvanhoeTaco IIRC.. its:

I'm pretty sure those are the exact ones I ordered. When I get home I'll check to see if I still have the receipt or packing list, because there are a few iterations of the 6303 and 6203 bearings. I tried to document and or track it all.. but between the multiple threads here and multiple photos on my phone.. plus time that passed.. I cant remember the details. I'll look more into it later though.

 

Awesome! The main issue I had even after I found them was trusting the source or manufacturer. But if youve ran them no issues I wont be scared.

 

Never had any issues with Timken stuff.

 

I just clicked the link, yeah timken is good, I saw a bunch of chinese stuff when I was looking

 

if i may add for those that drive where road salts/ saline winter road spray are used these conditions do change service intervals on your idlers. i have noticed mine even months old will start whining like kids come christmas.

 

Add those little bearing seal shields to help prevent or slow contamination.

 

This is a good idea. I am on my second round of the Timken bearings. The first set flung a lot of grease out pretty much immediately and this second set seems to be holding up better but I am noticing they are starting to let a little bit out. That plus all the dusty conditions I drive in I think those might be worth investing in.

 

Back from cleaning. Going to put them in with no lube and use 1/2 impact on fuel rail bolts to cram them in.

 

Don't forget red loctite and cross thread the bolts.

 

You'll also want to rip out one of the connector wire pins and reinsert. Helps practice troubleshooting skills with intermittents.

 

When I took injectors out I brushed all the sand and dirt into the holes because I want it to look fresh
