TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

Good, mine does the same.

 

The solid couplers noisiness at idle thing is normal @IvanhoeTaco

 

Mine sounds like monkey rape at WOT. At idle I used to hear rocks, now exhaust noises cover it up.

 

If every bearing in it wasnt new I would swear it was trashed. Idles great, tons of power, stays cool. All I can ask for.

 

The smaller pulley you go down the loufwr it is ... especially since the 4c4 conversion with the hole in the floor for the FJ tcase everything is louder lol

 

The cowl intake is a plus too

 

throw in a crawl box and its just like driving inside a rock tumbler

 

I can only imagine lol I thought I hooked something up wrong with hearing everything spinning haha. At that point I'll be driving it off a trailer

 

Free shipping from Lexus Westminster. Not the cheapest parts dealer but saves some hassle https://parts.lexuswestminster.com/

Great idea. Or just drive through some mud like some have suggested in the past lol. I ended up scoring a fairly new used lx570 TB but skipping on the adapters so it looks less modified.

 

score. anything that oxidizes it to look genuine. im so glad i dont have that bs.

 

So now that Ive got this spare 1gr...time to build. Another 6k for a stroker kit? Damn. @Torspd

 

6k? for the bottom end maybe.

 

my guess is its closer to 12k plus swap labor. i wish i could.

 

0$ for labor on my end. Stroker kits running for 6k on the interwebs with some preliminary searching

 

im looking forward to watch. i wish i could.

 

Has anyone tried ordering NSK bearings for replacements instead of the recommended Timkens? 3 of my Timkens have failed again under 1 yr of use, I think I am over their bearings. I'm not sure the NSK will be any better but this last time has got me pretty annoyed with them so I am ready to try something and be the lab rat for the group.
I'm looking at 4 of these https://www.qualitybearingsonline.com/nsk-6303-2rsc3-deep-groove-bearing-12x37x12/
I have considered trying these (https://www.qualitybearingsonline.com/nsk-6303-vvc3-deep-groove-bearing-12x37x12/) which utilize a noncontact seal, allowing them to spin to 15000 RPM instead of 11000 RPM of the contact seal bearings, but from I've seen that means they will most likely not seal as great.
The plus side of having to do this unexpected pulley swap today (thank got I have a spare blower setup laying around) is I finally got around to swapping in the titanium studs!

I know superchargers online has double roller bearings but the last few times I have called them it's like they don't know WTF they have or which pulleys they replace.. If anyone here has an invoice of them and which pulleys they replaced that would be great.

 

I'll be replacing bearings soon but may have to reconsider after reading yours. The SCOL upper idlers are PN 056-051021 & 056-052023. These are the Ø2.30 ribbed and Ø2.15 smooth pulleys. Lower Ø3.0 ribbed is 056-052030.

I messaged them about a group buy this week but haven't heard anything back.

 

Ok so going off of that tells me that they do not have a replacement for the tensioner pulley or the smooth pulley next to it. Good looking out because I can pick those up, the LFP and then I only have to worry about that stupid center smooth idler. That was actually one of the pulleys I did swap out so it clearly needs something a little more than what I have been getting. I'm not convinced that I am this abusive with my truck compared to others on here but I am starting to wonder. Especially since according to a YT video about the new TRD pro tacoTtoyota considers 40 hours of hard offroading equivalent to 300k miles

 

I could be wrong but compare the upper smooth for to middle smooth. If I recall, @12TRDTacoma mentioned it being the same as he installed the uppers but I'm not sure if I read that wrong. Hopefully he can chime in on it. If so may just do the full shebang this time. I've been running on squeaky bearings for more than two years already. And I already ordered an LFP pulley. If you want the measurements on that one, i can help. Last I heard, SCOL doesn't carry all the pulleys.

 

Are you still on the original bearings? The first go around with the timken's they started squeaking and all was good, had a few weeks to replace them. I didn't get that this time, last week I started getting a horrible grinding sound. Today after my oil change I investigated and it felt like one of them was starting to lock up, the other two I could feel the grit when spinning and could tell they had flung all their grease out again. Especially since it was all over the pulley instead of inside the bearing where it belongs
