TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

No. I played with that a few weeks ago. Backed it off until I could feel the butterfly stick a tiny bit upon re-opening. Then screwed it back in a tiny bit at a time until the sticking stopped. I did see a mild improvement in boost afterwards. So, I’m confident that it’s adjusted properly.

I wonder if I should be questioning the gauge (AEM failsafe) I think I’ve got an old diagnostic vacuum/pressure gauge in the toolbox. I’ll try hooking that up temporarily. Just to see what it says.

Who has a pulleyboys 2.5 pulley handy? Can you get me some quick measurements? I’m wondering if maybe this one I’ve got is perhaps slightly bigger or something.

 

Traffic takes care of that for me.

 

My truck did that to me one time. Started right after a fill up. Ended up being bad gas. that is when I decided to start carrying a bottle of Lucas in the truck with me at all times. It did it for half a tank until I got to a place to fuel up again and get a bottle of octane boost. Went away.

 

If the top comes off my SC to get to the butterfly valve, what gaskets to I need and where did you get them?

 

so glad I don't have to worry about that. Perks of living in a small town I suppose

 

It's unbelievable lately. Roads that were built new (shovel ready) just a few years ago are already being torn down for bigger/different ones. 10-12k people a month moving to the metroplex.

Star Telegram 3/18: "The Dallas-Fort Worth-Arlington metropolitan area’s 146,000-resident jump in 2017 was the most of any metro area in the United States. And six of the top 10 fastest-growing counties in the United States were also in Texas, including Tarrant, Dallas, Denton and Collin."

 

That is crazy. The only thing I like about the city is the huge highways and the tollways. 10-12k a month?

 

Tollways are closed courses...

 

That's what im saying. You pay to get on them, might as well get your moneys worth!

 

Oh and for the record, to those who I had been consulting with to help me track down a pig rich after fuel fill ups at the pump. I ended up tracking down the problem recently.

Purge valve was sticking open after fill ups and letting fuel vapor come into the blower manifold. I found it by disconnecting the hose leading from the valve to the manifold after filling up and plugging the port at the manifold with my thumb. Upon disconnection found not only my idle regulated, but the AFR cleaned up to the proper ratio. I replaced it and all has been well so far.

I suspect it is possible that the valve was the cause of incredibly intermittent hard start issues I had if it was sticking at random which would cause vapor lock and would not clear until the engine cleared all that excess vapor out of the manifold.

 

Glad you got it sorted! Where is this purge valve you speak of located?

 

Bolted to the base of the oil filler neck. Coincidentally right beneath the blower and the right above the piping hot valve cover. Perfectly exposed on both sides for heat damage.

 

Ahhh is this also called the VSV (vacuum switching valve)?

 

That's what Toyota typically labels it.

In layman's terms it's a purge valve.

 

Gotcha, know exactly what you're talking about. Were your intermittent hard starts just longer than normal amounts of cranking before it would fire up?

 

Yeah that thing is really sandwiched in there. I didn't like how close the hoses are to other surfaces so I added hose loom everywhere I could get room.

 

Fuck, I just looked at the driver side spark plug locations. I sense bleeding and cursing in my future. FML

 

With enough extensions and wobbly drives, it's not miserable. Just be patient and take your time.

 

Yeah I bought a bunch of those to do it. Just staring at it from the side and I'm already growling at my own truck
