TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

No not yet. I’m gonna get it ceramic coated before I put it on. It’ll give it good heat reduction and I want to save it from the harsh salty winters we get here. My current URD y-pipe is ceramic coated and looks awesome. It’s held up very well.

 

Aren't the front flanges 304? @Roostfactor ?

 

yeah, yeah, yeah.. lol Im still focused on getting these lightweight pulley's done. Otherwise, we hold off and go back to the overdrive pulley. but people have been waiting and I only have so much freetime to work on this stuff. If there was really enough interest, I could put the s/c crank pulley on hold, alter it to make it "oversized", design the other pulley's, and do a set. but, thats just so much more time and money. really worth it?

 

With the quick change pulley availability, and the efficiency range of the s/c getting near max with the smaller pulleys, it really isn't.

 

Of my y-pipe? Yes, 304. URD lower header flange is mild steel though.

 

This is where I was going. Which means your Y-pipe is already more chemically resistant than the URD one. On the topic of ceramic coating for elemental protection.

For the heat retention, it is still worthy.

 

Different ports on the dual vvti manifold

 

I know it’ll hold up in the long run. I also want it to look equally aesthetically nice for as long as possible. My URD Mark lll exhaust is also 304. I didn’t coat that, it now looks like shit. I plan to take that off, get it media blasted and coat that too.......I wanna get my bling back.

 

6.5 stock sc crank pulley ÷ ?? sc pulley x rpm is sc rpm.

I am using 5500 rpm for reference
3.0 11,916
2.8 12,767
2.5 14,300
2.3 15,543

2.5 is already at the end of the efficiency island so a 2.3 is adding a lot of heat.
I'll test a bit with the 2.3 on but it may be a bit much for a daily.

 

I definitely feel like I have reached the peak with the 2.3 in the time I have ran it. Anything over (well technically under that) is reaching past the point of the blowers adiabatic efficiency spectrum. Not to say you can't obviously, but you aren't doing the blower any favors past that point for sure.

 

I have one sitting in my garage if anyone wants to use it for I have one sitting in my garage if anyone wants to use it for R&D

 

@Roostfactor
With the NST and 2.55 it’s 14,860
The 2.3 would catapult to 16,476

Curious if the higher elevation would offset the heat or not.

Let’s make twin screw rotors that match the TRD blower Instead

 

Agreed! Meth can help with that for sure.

My issue is driveability. Sure power is there but it's much more difficult to keep it out of boost now. Going against strong headwind at 70 I was at 5 to 6 psi. Not conducive to good mpg's.

Also I dont think I would ever tow with it. Too much continuous boost/heat to try to control.

Gotta go do some tuning stuff and send some logs to the magic man @JustDSM.

 

I wouldnt mind comparing to ours. Bring it with you when you come out here G.

 

Meth will definitely help to cool but it will also take up volume for less air. So when are we cutting out some of the bends for a direct shot to the rotors?!

 

It's much more complicated than that. Our rotors are 60° twist I think.
The sc inlet and outlet are shaped and "timed" to the rotor pack. Twin screw, tvs, etc have more twist in the rotors making our housing useless unless extensive rework was done to port match the housing to the rotor pack.
Look at the outlet of any twin screw vs Eaton gen V and it's easy to see the difference.
I think it would be easier to fabricate a new sc in than upgrading rotors in ours.

 

Still determining battery relocation.
Once I get that done I need to build an airbox.
After that I can focus on removing the elbow.

Oh, and I have a few y-pipes to build too. A couple people have been waiting

 

Meth also is oxygenated so will add a bit back.

 

This has been a topic of conversation for a little while... We would need some serious measuring tools in order to get the proper dimensions and specs needed to size us a TVS design that would fit in there.

I have actually found the very expensive way that my overall fuel economy increases considerably when doing 75 and under. If I need to go up a hill, instead of lugging it along in the same 5th gear (since the tranny is not intelligent enough to downshift on its own obviously), I actually drop it to 4th to stay out of boost and keep it in vacuum longer. My mileage went up from 205-210 per tank to 230-235 per tank alone. Crazy!

 

@GT7 That's why I was asking if theres some sort of intake manifold adapter/flange that can be fabbed to bolt a Dual VVTI blower to a Tacoma. Guess it depends how different the intake plenum is on each engine.
