TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

The dyno is done...
Following read outs are at the wheels...
203.3kw
370nm torque
Also had LPG tuned. Runs bloody fantastic!!

 

looks like a bent exhaust valve on cylinder 4. just one tho. seems weird. tranny is coming out soon and then motor will be pulled. not till next week tho

 

Loose any bolts/bits recently? That does seem strange.

 

nope... it was right at the 3-4 shift it happened. maybe over revved it... @Torspd are there upgraded valves in stock size?

 

Ferra and supertech

 

On a quickchange pulley install, can I install it as a whole or should I install just the hub then screw on the pulley?

 

Install the hub first. Attach the pulley after the hub is properly seated. (Note that the hub will likely have to be recessed behind the shaft's leading edge for the belt to ride properly.)

 

Thanks Steve

 

Its slightly rotated. I rotated it for the easiest mounting to my current setup. If you want quiet power then you scored!

 

You may recall, @JuanitoBunito, but I should have mentioned you'll probably need a couple of washers or a socket to seat the hub properly (i.e., past the leading edge of the shaft)...

 

I want to get there, but I've been burning money lately. Too soon for me.

Have you figured out what broke yet? How much boost were you pushing?

 

Must be a lower hemisphere data translation issue. Let me help you out.

 

To add further, Ferrea used to be the only of the two to sell the stock size. Over sized were additional cost. They were at a slightly higher price point than Super Tech.

Super Tech would only sell oversized valves, and stock size were additional cost. May have changed. However, oversized means head work.

Look up both to see what the options are now, as that was from 5 years ago, when I ordered mine.

 

bent valve. dunno how 10 psi on 2.6 pulley

 

It fits fine in there with plenty of room. I cut off the stock hangers and welded my own back on in the correct orientation. Rotating it simply made it easier for me to mount up to my current exhaust without adding more bends.
I am not worried at all about the weep holes. It is close to the bottom so any exhaust pressure will force the water out. Drilling a new hole will not do much for you anyway as the internal baffles also have weep holes so you would only be getting 2 of the 4 holes anyway.
Just get that puppy on there and post what you think. These are on 3 Tacoma's and 1 FJ that I know of and all 4 of us really wanted quiet power with little rumble. That is exactly what you get and it works very well for our application.

 

Well shit!!! I cant afford all of this goodness. But so much want!!!

 

No doubt a step up from cams in terms of cost and install labor time. Getting 5 people committed to this could be a struggle.

 

Damn you people. I've been trying to stay away from TW and porn... Stroker kits... Want!

 

Is the idea behind this that the muffler is less restrictive since its for a v8, but quiet because its the stock one? Curious how much more flow this would have over my TRD catback muffler. But wait.. is this a 3" inlet or 2.5"?

 

3" inlet/outlet AND all 3" internals.
Yes, exhaust manufacturers actually get criteria from the oem's as far as how much pressure rise (resistance) to exhaust flow is acceptable for each vehicle. My theory is that it is a muffler designed for a 5.7 liter V8 with 395hp and 410 tq so it has to flow well enough to not be too restrictive for that engine. Since we are boosted and need the extra exhaust flow for best performance I set out to find something that would work for us with minimal restriction and noise.

I will post pics of the internals again here so y'all can see. Yes I cut a perfectly good almost brand new muffler apart because i am..........me.
