TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

Tensioner pulley spins the fastest

 

So you guys are saying I need to get 4 of them.

 

Maybe what I should had said was side load, a lot of tension from the supercharger crank pulley itself. I knew what I was trying to say, I just couldn't put it into words better.

 

If you don't already have the LFP idler for the tensioner, then yes you would need 4 of them.

 

I changed my RMS just cause I was in there when I did my clutch. I was less than 90k. Peace of mind for a cheap part.

 

Have not ran into any issues or need of replacing yet so still on factory. I think I am about at 20k on the setup now. What should I be looking out and what may start to go at this point? Damn $99 each woof they better last longer

 

The lower pulley bearing and the 2 on the top seem to be the ones which always trouble me first.

 

Ordered six new

$9 ikh22 iridium power spark plug, (pack of 1)

ikh22 5345 plugs. Rock auto had the cheapest price less than $60 shipped.

 

Got enough idlers for the whole class???

 

I'd go spec 3+

 

lol. Maybe I'll order a handful more and keep some around for guys that need/want them?

 

You know, back when I was doing all of that, there were several guys that were interested in buying one from me. I’m not sure if there is still anyone out there. But, you might consider cutting up a few more of those things and having them available for guys if they wish to purchase one already cut from you.

 

Not trying to be argumentative. Just feedback on that particular clutch. I definitely recommend avoiding the 3+.

The 3+ disc itself is ridiculously heavy. It acts like another fly wheel, but, this flywheel is on your input shaft! This makes up shifts super hard on your syncros and just plain not smooth. Engagement is often noisy. Especially during break in. Which, in my particular case lasted over 4000 miles. And, it still makes awful noises sometimes.

It does pain me a little bit to admit it, but the 3+ is probably overkill for our application.

 

It's overkill for sure. I think I was more optimistic of future upgrades rather than being realistic. That said my clutch pretty much drives like stock now and I'm hoping for decent life out of it since it is overkill but time will tell on that one.

Still noisy at times, especially in drive throughs

 

I put a urd stage 3 clutch with the heavy flywheel and man I hate driving it only when in 1st. Taking off and slipping the clutch is noisy as hell. And like you said, being in drive thrus or stop and go traffic sucks. Other than that, I like how it shifts once I am going. It’s the initial take off I hate. The clutch pedal isn’t to heavy to me either. Just noisy. I put it in October 2021. Only have about 3500 miles on it and at times it does seem to be getting better

 

Not argumentive at all. I had a different experience and it was for a different vehicle. Loved the 3+. Maybe on the 1gr side it's a bit much depending on application.

 

Mine doesn't seem bad in first unless I really have to feather it with low rpms which will cause some juddering. Seems very stock like except I maybe give a hair more revs in first.

Rated for 545 torque capacity for the Taco

 

Okay, I do want it to be Streetable as my wife drives my truck sometimes also. So Spec 2+ or maybe just the 2 might be enough?

Also, on URD's website, the vehicle description for the Spec 2+ lists only FJ Cruiser 6 speed 1grfe. Is that just a typo and it'll work for the Tacoma 1grfe? If I put in my Tacoma's year to narrow the parts search, the Spec clutches don't show up.

 

I’m running a spec stage 2+ on my Tacoma. The pedal is a little heavy, but even with a lightweight flywheel, it’s very streetable imo. It’s the spec ST913H. Rated for 440tq

 

I ordered mine from summit racing. Check specs website for the proper model, not URD
