TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

***Radiator Hose UPDATE***
Thanks to @mr.trd , I have received the lower radiator hose that came with our fit kit. Notice the difference between the OEM (trimmed/TOP) to the Magnuson provided one (untrimmed/BOTTOM). Big difference. The current OEM hose I have installed is trimmed, but still touches the tensioner/pulley bracket, and the radiator fan has cut a chunk off the side of the hose. Luckily, no leaks....yet.

Also, I have contacted Gerald (thanks @Murphinator ), from HPS, to replicate this hose for our application. The trimmed Magnuson hose will be dropped off on Friday. I suggested a combo (upper/lower) group buy when it is made. He didn't say no. LOL! Hopefully it gets made quickly. =)

 

nothing in the land of hipo is (specific).
snow does carry many options that can fill our s/c needs. if you have questions you cant find answers to pm me. ill share all i know

 

could you share some pics with hps? maybe they may make a new even better design!

 

That's a great idea! I'll forward those pics to Gerald.

 

you are asking very good questions sir.

 

I'm just trying to contribute a little. The wealth of knowledge here boggles my mind and I'm still not done reading the entire thread!

 

even if it was two generic hoses clamed together for a shape to be made. a clear idea of model helps. yes, ill buy one.

 

You know what? I can stop by autozone or o'reillys tomorrow, and see if they have similar hoses. For the people who don't want to spend the dough on HPS ones.

 

you arent alone. ive studied this thread for 2 years. fantastic use of time. ive made friends all over the us. we just all need to try nitrous now. all the cool kids sniff it.

 

Anyone get the cam gear mod done at a shop? curious how much it would run. I'm in VA.

 

I presume you've looked over my how to/for sale thread and decided it was over your head?

 

I did look it over and I think I can do it I just wasn't really sure how long it would take me (assuming everything goes right). I usually do simpler work on the truck. I'm all about eliminating hassles from my life if the price is right. How long SHOULD it take?

 

Diy time seems to be 4-6 hours for most that have tackled it

 

Id go on the upper scale of that. Especially if you dont do internal work that often. There is a slight learning curve on Toyotas.

 

It's actually pretty easy to do. First time inside my engine and it all went smoothly. I took the SC off and opened it up one evening and did the install the next morning. Didn't take too long.

 

So I need to replace my supercharger belt as it is cracking, and I don’t want to to fail on me in the middle of no where. I have a belt that I purchased a couple of years ago that I keep in my truck for the oh shit situation. Toyota part number PTR30-35110-AA. I’m going to put this on so I’ll be good. But I’m trying to buy another one to keep in my truck, and the part number is discontinued. What belt is everyone using now that the Toyota belt for our SC is no longer available?

 

Page 1 provides quite a few options. I think I have a Gatorback belt, but constantly changing to keep up with smaller pulleys.


Belt sizes and options:
- 70.5" length OE 3.0 pulley 5PK1790
5050705
Available in Dayco, Bando, Goodyear Gatorback, or Continental

- 69.5 for smaller pullies (2.5") 5PK1765 5050695
Available in Dayco brand, Bando, Goodyear Gatorback, or Continental

For sizes 2.8-2.7" pullies a 70" belt is what I recommend, though I have no good source for a belt of that length in 5 rib. Any belt which is 5 ribs or more will fit, however, anything further than 5 rib will require cutting ofthe belt with razor blade. Place the number of ribs [X]PK1778 in the brand you desire in the search bar and you may be able to find it.

UPDATED:

I have further researched belt part numbers for those wanting to run Gates FleetRunner green belts for increased longevity and increased pulley traction and have a small compiled list of near lengths close to what is required to run certain size pulley's on our superchargers. Below is a list of what size will be most compatible based on the size pulley you are running. All will require modification to fit our 5 rib pulleys.

- For engine (NOT the blower!) serpentine belt setup: K070835HD is a direct OE replacement fit
- For OE 3.0 pulleys (70.5"): K070705HD will require slicing off 2 ribs
- For 2.8-2.7 pulleys (70.2"): K080702HD will require slicing off 3 ribs ORK120702HD will require slicing 7 ribs (you get 2 belts for the price of one!)
- For 2.5-2.6 pulleys (69.56"): K060696HD will require slicing off 1 rib

Gates RPM series:

These belts are claimed superior to all other belt options for Superchargers. Running it will require the lowest configuration of 2.7, ideally OE sized 3.0 pulleys as the belts are designed to retain their length for the life of the belt with zero stretch factor premeditated on them due to their construction. Due to their inherent build nature which factors in zero stretch, sizing is critical otherwise snapping will occur. Be aware as well that those with the solid poly coupler installed in place of the OE spring loaded coupler will experience increased supercharger rotor noise at idle. This is NORMAL. Sizes are as as follows..

For pulley configurations 3.0-2.8 (ideally kept at 3.0) (70.57"): K050705RPM
If you do decide to play with these sizes with sizes below 3.0 be aware you may snap the belt. Belt sizing is THAT critical!

Belt sizes for 2.5-2.7 currently do not exist in the RPM series at the time of this writing (69.5"-70"). HOWEVER, by running @Roostfactor belt wrap mod for pulley sizes 2.7-2.9 it should regain you the belt sizing you need to reclaim that lost half inch belt loss you would otherwise have if you did not run it, therefore please refer to the previous belt size for OE sized pulleys. It should put you back into the OE length sweet spot.

For those running 2.5-2.6 pulleys I would strongly recommend running @BillDaCat8 belt wrap mod, as it reclaims lost spacing otherwise. If you are able to perform his belt wrap this would allow you to reclaim the belt length otherwise lost by stepping down sizes and it will allow you to run the OE length 70.5" size without further issues.

For pulley configurations below 2.4 ideally 2.3-2.2 (69.01" length): K060690RPM will require slicing off 1 rib

For pulley configurations below 2.2 ideally 2.1-2.0 (68.57" length): K060685RPM will require slicing off 1 rib

 

youve come to the right thread sir. welcome.

 

Thanks so much for the info, appreciate it!!

 

Id run the gates RPM belt if you're running the stock pulley. Very nice quality
