General Supercharger Thread

If all that really matters fuel wise is the AFR, then if you’re monitoring that and it looks good it’s probably safe to assume the fuel pressure is good right? Fuel pressure would be nice to have for diagnosis if the AFR was not on target though.

 

I paid 300 but spent 34 on the O rings.

 

In that context it makes sense now. I'm guessing it could act as an early warning if pressure drops you know you risk an issue like leaning out rapidly.

The gauge can be configured to read oil and water pressure too though it looks like it can only has ports to support one sensor at a time.

 

It has multiple gauge faces you can change out depending on if you want oil/fuel black/white background, will read any fluid pressure at the rating of the sensor, but only one sensor. It's good to have for comparative analysis, like if you're leaning out but haven't hit DC limits on the injectors, or if your pump is draining the basket too fast and doesn't have an adequate supply of fuel. Nothing will kill these stock engines faster than going lean.

 

RE: Total Seal Piston Rings. You are correct @armyoffoo Cylinder Type = Cylinder Quantity. Site is painful to browse:
https://webcatalog.totalseal.com/Home/Bore/3.701

Going back and forth with them via email they recommended SKU T3701XC-4 which is a supposedly a set of x4 Top and 2nd rings according to the sales rep however the SKU only pops up in Gapless 2nd.

What is included:

AP S/S top ring w/C-33 coating

Gapless 2nd position ring

3-piece standard tension oil controls


This is a 4cyl ring set with the following description, 3.701”bore 1.0mm top ring, 1.2mm 2nd ring and 2.8mm oil controls

One set of 4 = $239.78


Recommended Gap chart.

Edit: added Gap Chart

Edit 2: Pricing

 

Their site is confusing, I cross-referenced the bore and ring groove in their catalog. I probably should have spoken with someone first, but I purchased the following:
M3701XC-4 - Qty 2
T3701TS - Qty 8

Catalog options for our stock bore and ring groove size:
3701XC 3.701 1.0 1.2 2.8 1CYL RS Classic
3701XX 3.701 1.0 1.2 2.8 1CYL RS Classic
3701CS 3.701 1.0 1.2 2.8 1CYL RS Classic AP
T3701MS 3.701 1.0 1.2 2.8 1CYL RS Gapless AP
T3701TS 3.701 1.0 1.2 2.8 1CYL RS Gapless AP
M3701XC 3.701 1.0 1.2 2.8 1CYL RS Gapless Top
M3701XX 3.701 1.0 1.2 2.8 1CYL RS Gapless Top
M3701MS 3.701 1.0 1.2 2.8 1CYL RS Gapless Top AP
M3701XC-4 3.701 1.0 1.2 2.8 4CYL RS Gapless Top
3701CSGP 3.701 1.0 1.2 2.8 GP 1CYL RS Classic AP GP
T3701XC-4 3.701 1.0 1.2 2.8 TS1 4CYL RS Gapless

 

Yeah not sure the technical sales rep will be much more help to you even if you did talk to them. You may have better luck with the general info@totalseal.com or calling them directly.

I found the part in their PDF catalog too but doesn't give much detail. Can't even search their site's part search with their own SKUs or use Google "site:" to browse their store front.
Besides the part/SKU provided he said you need a "tuff" top ring like the AP included in the set.

 

Updated my other post with all the ring information to include pricing and kit content.

 

I already reached out to them via email to see if what I ordered will work, or if I should have gone with M3701MS for the top ring. Reading up on piston ring tech has led me to believe the Ductile Moly should be fine if you're not pushing crazy boost on alcohol, but their quick reference says that it's best for NA street applications, so wanted to be sure.

 

Crossing fingers. I ordered both a 6" and 8" PTFE hose. The 8" arrived but is too long. The 6" is on backorder till later this month. But Amazon had a next day delivery, submersible 100psi fuel line from Gates. Was just gonna use it for the Radom jet siphon thingie, but guess it's also going on the pump

 

That'll work fine, just don't over-tighten the clamps or it will "saw" through over time. I hooked the radium venturi on the return side using the green barb, it says you can do either the feed or return, I chose return to keep the feed free of restriction.

 

Good to know. Wonder if this should be a concern to E85 builds too.

 

Ok that is a good chunk saved. Good find.

 

Maggy lower airbox came in. Does the current Maggy kits come with the airflow accelerator? The TRD airflow thingie was only like $17. Glad I had already ordered it.

 

Definitely seals better at the fender

 

Nope they don't come with it. But definitely use the TRD piece that's was used most commonly.

 

I'm not the sharpest spoon in the drawer but how is this 270 (discounted & free shipping) in merch???

 

Is that the stock OEM bottom?

 

Seriously???

 

I fixed it. Just have to push the rubber TRD seal into the fender further. Not an airtight seal anymore, but it fits and better than the other one.

It's the Maggy lower airbox I got from SCOL. $55 shipped

 

Yup, TRD SC hose kit 220, gaskets & sealer 4x.xx, (I forgot no tax too!

If I had known what it comprised of I'd have just used the L brass fittings I already have from the SC to the IC. Live & learn.

 

^^^^ wow!!

 

Hey, new to the Mod game. Got a 21
Trail. Contemplating the Magnuson supercharger. This seemed like the place to post.

Some questions I have:

-Ballpark out the door price for parts/ labor at a Toyota dealer? (I’m seeing roughly $10k?)
-Any dash lights/ other issues after it’s done?
-I saw someone on YouTube upgraded their radiator when doing the supercharger. Is this required as well?
-Is this gonna void my factory warrantee?
-Is it a reliable upgrade?

Thanks, and apologies if these questions have been answered ad nauseam.

 

I was quoted 10k at a local shop

-Any dash lights/ other issues after it’s done?

Not if done correctly

-I saw someone on YouTube upgraded their radiator when doing the supercharger. Is this required as well?
no

-Is this gonna void my factory warrantee?
Yes, if not done by a dealer

-Is it a reliable upgrade?

Yes

 

Did I read I need to remove the screen in the TB gasket?

 

thank you!

 

That looks like the stock TB gasket with the criss cross metal thing. The one for the Maggy is just a normal O ring

 

Great! Bought something I don’t need

 

Since your questions were answered the only thing I would add is there are some but very few dealers that still do the install that let you retain your Toyota factory warranty. I think Sparks Toyota was one of them. They used to do installs within the last two years not sure if they still do. Someone mentioned a west coast dealership but I don't remember the name at the moment. You'll have to call around to dealerships to see if any in your area do the installs and allow you to keep the stock warranty.

Magnuson also offers a limited 3 year/36K mile warranty for any damage if their blower were to fail or cause damage. You can read the warranty card online to see what it covers. This is more precautionary and no substitute for your factory warranty. Keep in mind even with the factory warranty it doesn't guarantee Toyota will fix it. (well aware of Magnuson Moss)

As far as reliability goes, as long as you don't go too crazy chasing big HP without the proper upgrades you'll be fine. You'll have to pay more attention to maintenance items like oil changes and you'll want to let the truck warm up to operating temps before gooning around. There are one or two supercharged Tundra owners that have high mileage Tundras north of 200K miles. I think the most I've seen is close to 300K but only half of those miles were with a blower.
