Is the reservoir and pump one-in-the-same? Or is there a separate pump? Mine is not circulating, but I don't see any electrical wires coming to or from it and was wondering how it got power to pump.

Would this be the correct pump?

The pump is separate from the reservoir and is located in the front of the vehicle by its radiator. The pump is connected to the reservoir by hoses.

That appears to be the correct Johnson pump for a replacement, but it may not be just plug-n-play like the Ford Racing LIGHTNING Intercooler Pump or the TRD version of it. TRD part # PTR29-35062(made by BOSCH)

Trace the electrical, there's an inline fuse perhaps it blew open. Wires should be going into the fuse box under the hood unless the person who installed it routed it differently.

Anyone know if the TRD SC kit pulleys have sealed bearings, unlike the regular engine serpentine pulleys/tensioner, which are not sealed?

Reason I ask: my alternator just died, so I'll have to remove the SC belt / tensioner to get to the main serpentine and remove it. With ~90k miles, I figured I'd replace the main accy pulleys and tensioner, since those are known to crap out. However, should I also replace the pulleys and tensioner for the SC? That looks like another good chunk of $$.....plus I didn't even know the part numbers. Anyone with high miles on their SC and original SC pulleys/tensioner?

Thanks, Mike

I have several questions on your build. I am also running the URD mk3 but with the 75mm pulley. Also the larger tundra throttle body 76mm. How are you running the 70mm pulley on the blower without the additional spacer injector? Doesn’t cause a lean condition without the additional fuel?

Did I miss something? These numbers are too low.....that's below a stock engine.

My alternator crapped out @ 89k miles, so I went ahead and changed all the pulleys (main belt and SC belt), belts, and sparkplugs. I stared and stared at the sparkplugs, but couldn't figure out any way to change the driver's side plugs without pulling the supercharger off the intake. I know one or two people have mentioned doing it without pulling the SC, but never provided any details or proof. And I analyzed using swivels, short extensions, etc, and it still would have been a major PITA. So I pulled the SC off. First you pull the airbox off, then unbolt and remove the intercooler (12 bolts) and swing it out of the way. I hung it up from the hood with a few pieces of twine. Then you unbolt the SC from the manifold (6 bolts, which can stay in place...you'll understand when you unbolt them) and a few brackets/bolts, and swivel/move it forward. This way I didn't have to disconnect any coolant lines on the intercooler or the throttle body.

Be sure to use the proper sparkplugs: Toyota/Magnusson specs a step cooler plug when using a SC. And no autoparts store or online place will know which one: Per my SC install manual: Denso IHK22 (or 5345...same part), and check/set the gap (0.032). You could probably do a cross-reference and find something else, but IHK22 is what was installed in mine 10 years ago, and the plugs are still available.

The SC pulleys on my 08 use two different bearings: 6303-2RS (x4. 17mm (inner diameter) x 47mm (outer dia) x 14mm (thick)), and a 6203-2RS (x1 17mm x 40mm x 12mm). The local guy who rebuilt my alternator had the bearings in stock and swapped them out for me. To be sure, check the numbers on your bearings...I have no idea if TRD/Magnusson changed things over the years. For the main serpentine belt pulleys, I just bought the Gates pulleys mentioned in many other threads. Would have been cheaper to just do the bearings, but I bought everything in advance, online, and wasn't really planning to do the SC pulleys, until one sounded like gravel after removing the belt.

Dnyo'd at the wheels with the engine hot, in 2WD (still haven't located a 4WD dyno near me) with 98-ish lbs of wheel+tire on each hub.

If you assume nothing was wrong with the stock engine, then I was losing ~64 HP and ~85 ft-lbs, so it maybe makes 288 HP and 317 ft-lbs at the crank now.

My engine/compartment runs hot and the air intake is a consistent 120 - 130 fahrenheit; I've heard folks say you can gain an additional 1HP per degree colder intake, so I was maybe starting a bit far back, too.

Gotcha....I figured the numbers were at the wheels (not crank).....but still seem a little low, but I've never dyno'd mine so perhaps that's the real world. But either way, it does make a big difference :)

Found a great video on Magnuson Supercharger for 2010 plus model year.
Also you will see one the original engineer/designer which he used to work for TRD/Supercharger and now he is working for Magnuson.
Supercharger is definitely on my list.

I now own MikeTx's 08 TT and with it about to hit 95k (92kish on the SC) I'm researching the average time before overhaul on these Eaton M90's. Mike changed the oil every 30k so it's had service beyond normal there and I do not hear any noise from the supercharger at all. No leaks, seems to make boost as expected by my seat of the pants dyno.

As this thread is a few years old since the original posting I'm curious what some of the long term SC guys are seeing with maintenance (other than oil and belts) and rebuild... or even just replacing the coupler and doing a snout rebuild, etc. Rotor coatings? Whatever...

I've talked with Jon Bond, High Speed Labs and Superchargers online but have heard anything from 80 to 100k to 'when it makes noise'... so obviously it's subjective.

And on that note... who, if any of you, have you guys used to rebuild your SC?

And to participate...

Trans cooler install question

My SC kit is on the fedex truck as I'm typing this and I Have a question.
I was planning on installing a Trans cooler to the front of the SC's heat exchanger. Will this cause any issues in the cooling of the intake air?
