TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

I feel like Toyota really missed the boat on building an incredibly robust supercharger setup. Since they were already building a supercharger for this thing, what they should had done was build a off the lower plenum or build a full new lower plenum assembly which was the supercharger and created a straight forward design which would also allow the usage of a new (and supplied) over the radiator intake. Not only would this had created and allowed for the maximum power allowable to the supercharger with the smallest of pulley configurations, but it also would had opened up the table for those wanting to replace the TRD blower with a higher flowing unit if they outgrew what was already there. GM has been utilizing the straight shot out design on their Corvettes for years already. Why not take a page from their book?

 

Does anyone know how to check the numbers on the ECU/ECM? I have a module that I'm told is a TRD unit, but I would like to confirm this.

The low end power is just amazing. That’s 4th gear so 1.1. And for it to pick up speed like it does under 2500 rpms still mind blowing. @JustDSM is the man. Cant wait to install my injectors and cam gears. Along with a smaller pulley. Where these 2.3 pulleys at? Still running a 2.6 for reference.

You can also see my arm boost gauge is hitting 10-11 psi. But then boost gauge on meth controller only hitting around 9. What’s everyone think?

 

I have reason to believe you are hitting only 9 psi, especially with a 2.6 pulley. 10 to 11 psi sounds much different.

 

I hit 7-8 psig with the 2.7 pulley.

 

I think we need a VIR track day.

 

need to do some trimming in the rear first. tires rub. with any weight or heavy cornering. on the list of things to do.

 

Nice! I can only imagine getting that much pick up on my tank of a truck. I know ill prob never get there but excited at the increase in any form.

 

so for those that know more then me, what will 10% underdrive do again? I believe you could go to a larger pulley for the same boost apprx. http://www.atiracing.com/links/pr/Toyota-1GR-FE/index.htm

I have a nst pulley in the closet but I think I want this

 

Sounds interesting. But will the SC crank pulley fit to this?

 

I have no idea

 

The sound is based on SC pulley RPMs not boost numbers. But yeah you’re right the wine gets much higher for pulley’s under 2.5. Aka it screams

 

update me if you ever got responses?

tcr would be convenient, I might just pay them a visit in he following week or two

 

Curious about he holdout on LCE? They've done numerous 1GR's.

 

Was posting a few days ago. Before I get started should I swap my black widow venom 2.5” for the 3” version?

 

I called twice, @DocME called. I said, Im ready to do this and am completely serious. we talked for 30 mins about the specs and he never called me back or emailed. Doc said they were uninterested when he called.

Believe me I would have it done in a heart beat but they basically said no

 

Did y'all talk to tech support? They also recently fully built a 2TR. @MrCrowntown 's.

 

yes, tech support said no, I asked to speak to the manager or whatever and did so for 30 minutes

 

@Reign808 needs help with bad bully dog corruption

 

Throwing a p0300 and p0012 on the freeway to work about 60mph.intense shuddering and misfiring, rough idle. Knocking on idle. Turned off for ten minutes then restart for a smoother idle but still rough. Misfiring.
