TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

Yes. I get the same number. Measuring the Tacoma tube, I get 3.125"

I'm betting that the OE Tacoma air filter measures 3.0". Don't have one handy to measure.

 

I have mine. Let me see if I can measure it.

 

It was just as I originally suspected. 2.75" @BillDaCat8

The FJ/T4R tube offers approximately a size bump increase of .5" ID overall over stock OE Tacoma airbox applications.

 

OEM Airbox measures in at ~2.9550"

This is the measurement of the actual diameter of the airflow tube inside the stock airbox. This does not account for material thickness. Just the internal ID.

 

Taken with calipers? I was just using a tape measure on mine, so there was a lot of room for inaccuracy with my method.

Am I wrong here?

 

I have the CVJ axles. There are quite a few options on the website

 

it’s the width of your measuring implement. You’re not reaching the true “bottom” of the MAF tube.





3.0855-0.1255=2.9600

 

I had a feeling. Okay that makes sense.

Well regardless of the OE size, I do know one thing is for certain. The MRP MAF tube adapter which I ran on my URD intake prior to switching out to the TRD has an ID of 3.25 with an OD of 3.5. I based the TRD intake tube mod off of what I currently had in the modified URD setup and things appear to be running just peachy. Justin I'd be happy to run a log just to see if anything has changed for you as soon as I get my replacement AEM drop in panel filter either tomorrow or Thursday.

Send it over!

 

With the 2.3 you better have that gasket on good otherwise the internals are going to take a good bite out of it

 

No problem! I'll have it here in a few days for you. It was a risky move, as I previously PM'ed you about regarding all of it, but ultimately decided to take the plunge after finding out the MRP tube was actually the same ID as the FJ/T4R tube.

The things we do for the state of California.

 

It causes me to shake my head at times, but I get it. Makes it challenging, that’s for sure!

 

Cams are in.

 

I get 3.61-0.269= 3.34" for the FJ tube re-measured with a badder asser tool than the tape measure I used before.

I suppose I was thinking that having these numbers might help with calibration.

 

awesome data to post brother. thank you.

 

Awesome! It's even larger than I initially anticipated. Evidently the FJ/ T4R tube is plenty suffice for the job in preventing MAF max out for us running out smaller pulleys.

 

I'm still working on that post. There'll be more added...
