Straight cut spur gear
Fits engines up to 475 horsepower
Maximum airflow: 700 CFM *
Maximum boost pressure: 20 PSI *
Absolute maximum impeller speed: 65,000 RPM
Adiabatic efficiency: 76% **
Available with straight discharge and clockwise or counter clockwise rotation

BPV’s
Forge 007
TurboXS Type 25
Bosch 110
Any internally recirculating BOV
50/50 Hybrid’s- Forge Hybrid, Go Fast Bits hybrid, Ebay Dual Blow off with recirculating.

NO FULLY ATMOSPHERIC BLOW OFF VALVES- Will cause a lean setting when you shift, the MAF needs the air to recirculate back through it so it can get a proper reading.

Belts
Gates K070890
Use that one, the Goodyear Gatorback has a very bad tendency to slip
For use with the 9.5 Pound Pulley

Pulleys
NST 9.5 Pound Pulley

Intakes
DO NOT USE WITH OUT A TUNE YOU WILL RUN LEAN
MMW Supercharger Intake
Umnitza Carbon Fiber Intake
Hybrid Cold Air Intake
ARC Cold Air Box

You can cut out the hydrocarbon filter that is on the top of the adapter that makes your airbox lid fit on the TRD supplied airbox bottom. Cutting this huge white screen out makes for about 1-2 WHP and increased throttle response.

Spark Plugs
The plug to use with the supercharger is the Denso Ik24 gapped to .040
Its 2 steps colder than stock and 1 step colder than TRD spec’d one

Rebuild Info
Bearings-
For the impeller shaft bearings
2 Nachi ball bearings nac-6003 (must be speed rated to 65000 RPM)

For the main input shaft bearings
2 SKF Ball Bearings 6205/C31

End Part / shaft assembly....
There are two end bearings part number 6205 2rs
Seals-
25-40-7 is the metric size of the shaft seal.. Timken part #222540


Taping Boost Gauge Line
Tap the line for the boost gauge rite after the Vac line from the throttle body, but before it gets to the T-Fitting for the ByPass Valve and you will get a much better reading.


Catch Can Related
On the intake manifold you have a traditional breather hose that comes off the valve cover into the intake manifold. And another into the intake. Cap off the manifold and route your breather line to a catch can or back into the intake "I prefer a catch can to keep the intake assembly clean and keep buildup from happening on your intake valves and ports." Also oil vapor lowers octane which can cause your engine to pull timing and then a loss of power if it senses knock". The best part about fixing these issues is you will gain throttle response and I gained around 1-1.5 psi across the board which means I was most likely leaking a small amount of boost back into the intake.

Turbo Timer-
I would reccomend getting a timer so it keeps your car running and cycles the way hot oil out of the supercharger. It takes about 10 minutes to install, and costs about 100 dollars for a new one. Or you can stay in your car for 30 seconds extra, either way your call.

Ecu Reflash-
It must get done, and it must get done at Toyota. Its not something every dealership can do, due to needing a special software tool. It is tuned very very conservatively and you can run a 9 or 9.5 pound pulley with no problems on the stock supercharger fuel map.
People have gotten about 230whp with the stock pulley though with just a retune on a Unichip Engine Management, so that’s always an option aswell.

Noises
Whine. The supercharger whines, it whines at idle, midthrottle, and under full throttle. It’s a fact of life and you need to accept that’s what it does. If you hear a put put put put noise at idle that’s the BPV getting stuck open.
Intake. If you get an intake you will hear your little BPV hiss whe your shift, that’s the only way to hear a hiss unless you get a Hybrid BPV.


Oil
Toyota recommends between 4.0-4.8 quarts of 5w30
I personally run about 4.5 quarts of 10w40 so it wont leak as easily because it’s a bit thicker than the 5w30

Boost Levels in HKPA via Digital Boost Gauge
-.58-.60 at idle in neutral (VAC)
-.70 coasting in gear (VAC)
.60 (8.7PSI at 6000rpm)
.62 (9.2PSI bouncing off rev limiter)

EVERY GAS FILL UP check your OIL level every time.

I can't remember where I read it, but someone said they had called TRD and specifically asked about this recommended maintenance and TRD said this was a typo and it was meant to be 30,000 miles. This makes a lot more sense to me but I can't confirm this to be true. Good write up though!

You can also use nachi 7003 speed rated bearings, same bearing just different part#.

BLUEMEANIE

its got Helical cut drive gears, as opposed to straight cut gears.

kikcaffine

Not according to their website!

This thread below has extremely valuable information in it also. It has really great pics of the SC torn apart and a lot of good info in general. A ton of reading though, but informative.

https://www.scionlife.com/forums/vie...065&highlight=

Also, this is where the discussion was about the 3,000mi oil screen cleaning. I am glad to hear that 30,000 is recommended.

x4 stick it

Stone128

Don't take my word that it is really 30k. I just remembered hearing that in a post but it could be wrong.

kikcaffine

Mine is essentially the condensed version of that posting.

Has anyone have the speed rated bearings fail ? I remember hearing about pulley bearings but never the speedrated ones.

BLUEMEANIE

hmm... toyota's site says they're helical cut drive gears, as opposed to straight cut gears to reduce noise. I even cut/paste'ed it from trdsparks cause I had to double check.
Could be a typo or it could be something Vortech did for toyota so it would be quieter for daily use for the normal average consumer. ???

they are helical cut drive gears

This was from garage's thread

cessblood

I think someone made another thread like this before.

Nychold

Is there any advantage to straight cut gears over helical gears?

Sleep3r

hey kikcaffine why dont you add info like:

bird chirp noises / chattering are normal at idle
muffling / wooooooo sounds at about 3k rpm +/-are cause by OEM BPV are normal
and state the normal pressure numbers for vac at idle and air/fuel (i dont know that)

Thank you

kikcaffine

Ok I will, Im actually about to make a revision in the next week

GammaTNT

iTrader: (8)

After installing S/C, do i have to add more than 4 quarts of engine oil? or 4 quarts should be ok? I thought the S/C use the engine oil to lubricate, so i might need more/

Sleep3r

i put 4 and a half quarts

kikcaffine

Like wise, thats also in the revision. LOL
