Magnuson Supercharger Mega Thread for 16+ Tacoma - Unboxing, Install DIY, Dyno Video

This, I found the 87mm pulley made the truck more enjoyable to drive. Power comes on sooner and just smoother. Running ott tunes

 

You mention that 'you really need to get on it' to see the power, this sounds to me like it is possibly the throttle position and load, that there is enough vacuum for the bypass to be open, and you need to get into the throttle, for the vacuum to drop, and allow the bypass to close. It is vacuum open, spring closed.

Take a mini vac and play with the bypass, and also lube it. Mine was a bit stiff originally, and I freed it up with some oil.

you also could verify that the bypass closes properly, as I understand it, it should hit the stop screw just a few thousandths before the butterfly bottoms against the aluminum housing. Many adjust the stop screw (special or cleaver tool required), I found that the bracket with three bolts in it, is slotted, so loosen these three bolts just right, and tap to rotate the whole bracket, to dial it in. Worked well for me.

I also second the exhaust restriction, as a limiting factor, I upgraded the exhaust.

Not sure putting it on a dyno and hiring a tuner will get you what you are looking for. Dyno runs are typically WOT runs ( unless you have access to a constant load dyno), and your complaint is that you expect more power without needing WOT. Tuning possibly could help, but it is more subtle than what you wold learn on a dyno, and would require actual driving around, to dial it in better. Lots of time, and not exactly sure you would find what you are looking for.

Just my thoughts, but unless something is wrong or out of adjustment, My experience is the SC makes the truck night and day more capable and more fun; suggest you don't loose sight of how far you've come.

 

Are you saying that sometimes it has normal power and under the same circumstances sometimes it's lacking the usual top end power?

 

No. It has normal power in the upper "band" and I define that as the 0 to 30mph range, the thing goes. But once I am running at 60 mph and i want to get it to move, I have to like really step on it, and it comes alive again, but i feel it does it at a lower pace as opposed to in the front end. And this only happened after the OTT tune. It was actually inversed in the original maggie tune, it was really slow in the front end, but then at higher speeds it woke up. It is like the tune inverted where the power comes in first. I'm ok really, and I dont really need to be running around like crazy, but I just noticed that change. That's why I was thinking, should I dyno this thing and reference to a baseline and then put the tune guys to dial it in. But maybe not.

Really appreciate all of you guys. All of you are awesome with the great feedback. What a great group of folks here.

 

Thanks Bud. What a wonderful note and advice this is. Much appreciated. Great group of folks here on this thread. You guys rock.

 

Yes when ECT is engaged there is a considerable step up in performance. I think I might just leave there from now on, although at times is too jerky to my taste especially when starting from lower speeds. Thanks to all for the great comments and feedback.

 

I switched my ECT button to the MESO Stealth Pro Shift KNob, so it's easier to access. I too have the same problem with jerky throttle at low speeds, so I typically hit ECT after getting up to speed. Otherwies, I'll chirp the tires.

 

0Hey y'all. I just had to pull my supercharger off to get to the valley to deal with some mice that chewed my knock sensor harness. Bastards. There was some oil in the supercharger and in the CAC - I'm assuming blow-by. Who's put in an oil separator with their SC, did it do anything for you, and where did you cut it in? Anyway, is there any while-you're-in-there tasks that I should do with things torn down this far? Do the knock sensors fail around a point? I'm only at 65k. I did the spark plugs when I installed the SC at 31k.

 

I did the catch can way before the SC. I have had 1 oil change since the SC install and I didn't notice more oil in the can compared to NA

 

I don't think these catch cans do much of anything. The carryover is so small that sometimes is hard to quantify it. It would be another thing that has to the connected, braced, maintain etc. The ROI isn't there IMO. But heck..what do I know. Let the masters weight in and see.

 

You can always bypass the catch can and do the PVC reroute

 

This won't help with oil in SC or CAC. It just changes the pick up point from the back of the valve cover to the oil fill tube.

I have one on my supercharged Mustang for this same reason. I don't think the engine ingesting a tiny amount of oil causes any harm but didn't want the intercooler caked with burnt oil.

 

This is only an issue with an air-to-air intercooler. This SC runs air-to-water.

 

The intercooler on both my Cobra and this kit are after the supercharger and air to water. They're subject to the oil that makes its way into the intake from the PCV valve. It probably will never cause an issue but the oil will coat the intercooler.

Decent video showing what I mean.

I’m getting close to pulling the trigger on this thang.
Trucks got 25k miles. Fully loaded with fishing crap it’ll pull like a MF in 3rd up steep incline/high elevation. She’ll hold 4th for a while, but it’s pretty inevitable with 2 150 qt coolers, and an 80qt…not to mention the rest of the camping crap lol

so - let’s get this all in one place. While I’m there installing;
- new plugs (stock? Stock gap?)
- new intake manifold gaskets
- shouldn’t I change the injector o-rings?
- I read it somewhere, but there’s a restrictor to remove?
- and install barb fitting for boost gauge prior to blower installation?

 

I installed the boost gauge and left the hose coiled up in the engine bay so all that is left is to hook it up.

Yes on injector o-rings

Keep the restrictor

Stock plugs work

Double check that you can tune the truck. Probably the first thing you want to do.

 

Sorry if I missed it. But what do you mean double check that I can tune the truck?

cause I’ve been on 0b04 for several years now, and have an OTT tune..

Sorry I just need a little clarification before dropping some coin lol

 

Need maggys tune or SC specific tune. If you use a regular engine tune it will blow your engine with a SC.

OTT requires you run the SC for 200 miles on MAGGY tune to make sure all is going right before OTT tune.

 

I understand that. But what does, “double check that I can tune it” mean?

 

A week before I had my install the tuning software was updated and it wouldn't log into the server unless I updated. I got it figured out after a few days but I was pissed that it was an issue so close to install.
