TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

Shouldn't you be in 4th gear (assuming you have the 5spd auto) for the 1:1 to get the best numbers? that does seem low though for a 2.5..

 

Sunday game plan. I so excite!

 

I haz exite 2!

 

So many cars running around on the road with reliable e-fans. If "one more thing to worry about" was a real excuse, none of us would have blowers.

 

If success, I make a movie film.

 

Valid point sir. How does the parasitic drag of a fan and clutch compare to the load on the charging system? Is there a lighter (load) on the motor with either?

 

Well put, I don’t feel any nerves around the e-fan. It’s Spal, it’s a good brand.

 

I noticed a little bit more butt dyno power after removing the clutch fan...

 

I would assume that the case. I understand to power a fan like that it takes ponies as well. Would the e-fan be better for slow mph? I spend stupid hours crawling in traffic.

 

That’s what I’m hoping for. Should be better for low rpm crawling and traffic. If wired to come on with the a/c, then you a/c will get cooler faster.

 

E fan cools better at low engine rpm compared to a mechanical fan. I believe I read somewhere about the results of a test that proved that the extra electrical load on the alternator still caused less parasitic drag than a mechanical fan.

 

Probably a better route for my needs. My truck only sees two driving styles here. Traffic crawl or haul ass.

 

With my Efan my a/c SHOULD blow icicles in the summer. I used 90's Thunderbird fan.
It was a pain to fabricate and install though. Also I have a pwm fan controller and my first fan motor died after a month or so.
I just replaced the fan motor only for a MarkIII fan. I'll see how it lasts.
It is a good thing I always listen for the Efan running when I shut the truck off or I wouldnt have known the fan motor failed!
There is a lot of truth to the reliability of the the clutch fan BUT efan works better for a/c and low rpm use no doubt.
My controller automatically adjusts fan rpm so it only runs as fast as needed to keep the engine cool and a/c trigger turns up fan speed to whatever you adjust it to.

 

I have two.

 

I really like that controller!

 

Yeah I'm not sure if the pwm controller burned up the first motor or not so I switched controllers from an AutocoolIII to the NB100. The NB100 has capacitors in it to smooth the power output pulses.

 

This is true. The guys on Engine Masters also did a multi fan comparison. Testing the losses of each on a dyno.

 

Thanks for the controller idea.

 

Pretty sure I read it in a magazine back in the 80s. Glad to know others have also done it recently

 

Correct, 4th is 1:1 but I can't hit redline because the speed limiter
