Super Charger Questions/Answers Thread

I recently had a SC and TRD exhaust on my 2013 Tacoma Double Cab 4WD V6 Long Bed LTD. I have been posting comments and questions in some other threads, but felt like I was too often getting off-topic and "thread-jacking". Anyway, I wanted to start this thread so that people that have SCs or have questions about them can ask them here and hopefully with all of the knowledgeable guys on this forum, we can get some good tips and advice.
My first question is this: I want to put a boost gauge in and already have an Insight CTS and the pressure adapter kit to add to it. I was wondering where do most people tap in to install the boost sensor? Someone mentioned that they had installed an inline "T", but what hose to you attach to? Pardon my ignorance, and MUCH thanks for any advice.
Ken

There's a boost port on the back of the supercharger that has a rubber vacuum cap on it. Remove cap, connect boost hose to it an your gauge.

So, I have heard a few different versions of how the Tacoma reacts with the S/C.

On one hand I have heard that if you keep the RPMs below 2500 the S/C has almost no effect on how the truck drives and that you don't really know it's there.

On the other hand many have said that there is noticeable power increases, or at least a somewhat noticeable difference regardless of RPM.

Which is true?

almost all of my driving is below 2500 PRM unless I am really working it hard on an on-ramp. Even when I tow my 18' Toy Hauler it stays under 2500 rpm most of the time.

My question relates to if I will see minimal benefit with the S/C and my driving habits?

I JUST got the truck back on Thursday and have only driven it two or three times since I got it back. The first time I didn't think I noticed it that much and the mechanic said it might take a little while for the ECU to relearn some things (the ECU had to be re-flashed). The next time I drove it I got it up to about 20mph driving slowly and then stood on it and it was up to 70 in NO time. Since then I can notice an overall improvement in power most of the time, and can REALLY notice it when you stomp on it. Does that make any sense?

Here's a picture of it. It keeps a 1:1 ratio for fuel to S/C BTW that's the FPR Mod

As Helmut, and Bloody said^^^

And when you install your boost gauge you will "T" off of the line Lord has run off his FPR to boost port for optimal fuel pressure..!!

It simply increases fuel pressure with boost pressure so that your injectors flow more fuel than they can at 43.5 psi.

Here is a thread about it. http://www.xr-underground.com/forum/...ad.php?t=50532

I knew you would straighten out the facts in this thread as usual

From my experience in the last week of driving with my supercharger. There is noticeable benefits even below 2500 rpm it's just harder to hear it or tell it's there. Truck really seems to accelerate even more effortlessly than before even while keeping your foot out of it.

Oh man, thanks guys, much, MUCH appreciated! Lord Helmet thanks so much for the info on where to "T" into the line for the boost gauge and thanks for the heads up on the FPR (fuel pressure regulator?) mod and the links.
I did get some pictures of my truck and where the boost line cover is and also found an electrical connector that I found near the tubing plug for boost and have not idea what it is for and if it is supposed to be plugged in or not.

Pic of the plug cover:


Another pic of plug over tube connector:


Yet one more pic of the plug cover:


And here is the pic of the mystery connector not plugged into anything:


Sorry for my ignorance, stupid questions and please let me know when (not if) I ask a dumb question.
Thanks again to everyone who is so eager to help, I REALLY do appreciate it!!!!
Ken

Shit I can't remember off the top of my head what it was originally connected to, but it doesn't go anywhere. Tape it up and hide it away.
