General Supercharger Thread

To those that got rid of the secondary cats, are the midpipes still double walled at the secondary cats? I’m just wondering about when you weld pieces of pipe in their place, do you just not worry about the inner pipe being the true flow path and weld to the outer pipe? That seems like it would cause a lot of the turbulence in the exhaust flow if that were the case.

 

@Silver17 I believe it's just after the cat in the bend but not 100%.

 

Single pipe if I remember correctly. Either way can't be any worse then the cat itself being there lol

 

y'all, I need an assist.

SCOL says these are the 3 items I need to replace my stock airbox.

do y'all concur?

and - what filter does this take?

 

You don’t need the rubber intake tube, it won’t work with the Harrop. You have to stretch the Harrop intake tube over the new airbox lid (it’s a real PITA but doable). You just need the lower base and the lid. Filter wise, any filter that is for an 07-13 tundra will fit.

 

What about the TRD intake?

would I need to re-tune? or is it a simple swap?

or is the SCOL version a better option?

I guess it depends if you want the larger intake MAF tube or not. The SCOL magnuson lid has a larger MAF tube so a tune adjustment is required for that aspect. The standard TRD intake for NA trucks which I believe you linked should be plug and play for your stock airbox (can’t comment on the filter size for that one). If you get the TRD SC intake box though then that’s the same situation as the SCOL magnuson intake box as it’s a larger MAF tube.

 

I have been getting sporadic P0101 codes, I also had 30% ethenol so needed to reset in Techstream, version 17 said it has been decommissioned & wanted me to update which obviously I can't do through their link so I set my laptop back a year. I really only use this for the truck so it isn't the end of the world but anyone know where I can find a viable version?

 

I’ll sell you my stock sized 3.6” ID TRD intake if you’re interested. I upgraded to the SCOL Magnuson one that is larger at 3.86” ID.

 

The red letter TRD intake top IS NOT the 3.89 mm. You need the black lettered TRD Box. I posted that part number somewhere in this thread. I'll do a search later when I get some time

I guess I'll need a tune. hello 500whp


y'all are killing me.

 

I think I'm gonna postpone the install a couple weeks.

the Truck goes in the paint shop FINALLY. to repair the tornado damage from 1/24/23. (just paint damage)

I'll confirm the MAF tube diameter once it comes in.

I guess it would be cheaper if I went back to Peitz, since he has the present HPT tune.

 

speaking of Peitz, HPT & 2650's

good numbers on a bone stock Chevy.

The TRD box with the red top is the same MAF tube as stock (3.6x”) so you should be good, no tune adjustment needed. I’d argue that if you were replacing it anyway you SHOULD get the larger intake (3.86”) and get it retuned, but if you’re happy with it how it is then i guess there is no point. The black TRD airbox like @M3Tundra-JK was using in his truck is the larger one, and is the same diameter as the SCOL magnuson box.

 

good. appreciate the feedback a bunch.

1 less thing for me to forget to do.


knowing my luck, when my truck is in the shop, the rental I get will be a pink hyundai. trying to get a F150 EB rental. we'll see.


life is still good.

 

That’s a 6.2 as well. Cool to see the tundra can put up similar numbers at the wheels to a 6.2 with the same blower and a 10 speed. I wonder how much power a stock 6.2 is good for reliably without having to beef things up?

 

considering we had 2 6.2's drop their lifters.....they can't handle N/A numbers.

 

If I bought a 6.2 I’d be buying one of those modules to disable the cylinder deactivation on day 1.

 

I'd have my Wife commit me if I bought a 6.2.

lol

 

Getting ready to order the following and figured I'd ask to make sure no one has spares they're looking to sell.

-Harrop stage 1 kit from SCOL (buying new)
-Magnuson/SCOL upper airbox (should mate correctly to my '07 larger airbox)
-DW 650cc injectors
-Radium single catch can

Already working in HPTuners, so that is covered. Wideband will be installed in the next 2 weeks, actual SC *may* have to wait until after our move to Austin, but the fuel pump will get installed in my shop in OR before we leave.

 

you need to add the 80mm pulley.

 

Yes, forgot that part. 80mm pulley will be ordered, but I'll do initial tuning on the 85mm.

 

Response to last weeks request for the Magnuson upgrade cost:

Good Morning,


We are anticipating receiving info on the upgrade kit details veery soon. At this time, we have not been provided the details on cost, components, etc. quite yet.


If you are interested in the upgrade kit, please email me your address and contact info and I can work you up a quote once we have more details available.


Thanks

 

The Larry Chen truck in the video shared here has it:

Yes, but just like with most businesses, Magnuson will organize people receiving their kits earlier for the purpose of doing videos and stuff to drum up hype and whatnot for the release. My business partner was one such lucky individual with the 3GTacoma magSC, installed and with video taken at/by VR Racing in Arizona.

 

Harrop has sold an upgrade kit for their 2650 unit to adapt to the magnuson 1900 kit for a while now I believe. It appears there is some kind of allure to the magnuson products over the other brands, but I haven’t figured out why that is yet. I guess the name just sounds cool?

 

Sure that is typical.

According to the post I was responding to it is available on the Maggie site for purchase.

The purpose of my post was resharing the link for folks that wanted to see it installed in a truck and and where the user shared their performance #s.

Several people have come along asking about it to see who has it but the blower just came out.

It also seems like folks are expecting different performance #s when it is the same size as the Harrop using the same rotors. It is also not changing the engine's limitations.

 

And without before and after dyno runs, the power numbers are worthless. I will never understand why people don’t baseline.
The shop that did my install didn’t plan to do a before dyno run until I insisted on it and paid extra.

 

Sage advice

Given equal epquipment, I expect all 2650’s to produce about the exact same numbers.

Are the cooling bricks on the mag about the same as the harrop- other than being upside down.
