This is where I found that bolt: http://dmpfasteners.com/, these guys will have anything you need. To remove just take off shaft, find a nut that fits over the pulley bolt and have it welded over it, then remove with an impact gun and you're done, this is the quickest way to do this, I've done it 2 times now, good luck.

 

Did you use Grade 5 or 8?

 

Grade 8

 

Oh Noes! Somebody has swapped my Forge Splitter with a POS BPV!



Noooo... it's been installed on my tC!!!!



I am already enjoying the massive benefit from it. I've got it set at 27 clicks (I think). I had it set at 20 clicks when I installed it then I fired up the car and it was already passing air out the horn. I'm keeping it in hybrid mode until I have it set up nicely then I'm going to switch it over to full recirculation.

I must say, if anybody who owns a S/C and hasn't swapped their BPV... DO IT!!!

 

Nice^^^^I agree with you, swapping out the the stock BPV is one of the most beneficial mods you can do to the tC, the stock one does not hold boost very well.

 

Hey soccerwama go for a Cruz tonight let me know just got my car going again got some friends coming

 

I purchased a 2009 Scion TC with 12K miles on it in June 0f 2009. The car was like new (but much less expensive).
The previous owner had done a number of modifications (TRD Supercharger kit, body kit, new instrument panel, TRD lowering spring kit, sway bars, EMX Super 7 18" alow wheels and ultra performance tires, HID headlights, headlight "eyebrows," rear taillights and license plate lights, OEM foglights, all interior LED lights, short throw shifter).

The only modifications I made were adding a TRD catback exhaust and a Pioneer AVIC X710-BT GPS/stereo and Pioneer XM radio tuner.

I also purchased a set of Blizzak WS60 snow tires for December-March driving in my region.

I currently have 30,000 miles on the vehicle.

The following is my vehicle history as well as a few maintenance tid-bits:

-Engine oil changed every 5K miles using 10W30 synthetic oil and TRD filter.

-The snow tires are a must for winter driving this car and are fantastic tires. Very little road noise and they handle almost as well as the warm season performance tires.

-The Pioneer AVIC X710BT unit is a bit quirky, but overall I am satisfied with it and it integrates very nicely with the car, steering wheel controls, etc. However, if I had to do it again I would not buy this unit.

-After having the car for several weeks, could not get the low tire inflation indicator to turn off permanently. I returned the car to the dealer where I purchased it (Koons Tysons Toyota/Scion in Vienna, Virginia) and they installed 4 new tire sensors for no charge (for some reason the sensors were never installed with the 18" wheels).

-Under heavy acceleration, Supercharger vaccum hose blew off causing engine to run very poorly, etc. Wish I had diagnosed this myself, but I had car towed to my local dealer (Leesburg Toyota/Scion) which is not where I purchased the car, but closer to home). After a day of trouble shooting, they fixed the vacuum hose and charged me $350 for towing and labor. As the car and SC were still under warranty, I complained to the service manager, but got nowhere since he stated this was an owner-installed unit and the vaccum line was not fastened correctly.

-I called Scion customer service and, after some back and forth, they agreed to do a one time "loyal Toyota customer" refund for the entire amount. That was well worth the time spent.

-CEL came on at approx 16K miles. After a day of troubleshooting, the dealer where I purchased the car (closer to my work location) replaced the catalytic convertor and the an idler pulley (they noticed the bearing was going bad) under warranty. No charge including a new Toyota loaner car while the car was off-line for 4 days. Koons Tysons Toyota in Vienna, VA. They have been really awesome.

-At 27K miles, intermittent squeaking noise from under the hood. Koons Toyota diagnosed, could not find a problem, attributed it to normal SC noises. No charge for diagnosis, but I felt there was still something wrong, possible a SC bearing.

-Under hood noise persisted and got worse. At 30K miles drive belt almost completely failed; I barely made to the Koons dealership and they replaced the SC idler pully again as well as the damaged belt. Once again, no charge including a new Toyota loaner car while the car was off-line for 3 days.

Overall, considering the price I paid, I love the car. I drive it 18 miles to and 18 miles from work each day with an occasional longer trek. It is an EXTREMELY fun car to drive; very quick and handles like a dream. I am no youngster and this car s very popular with the younger crowd, including my 16-year old.

The dealer (Koons) has provided stellar service and covered everything under the warranty, even though they can find no record of any Toyota dealer having installed the Supercharger. So, other than the inconvenience of having to return to the dealer several times, I really can't complain. Having any aftermarket (even though it is TRD, it is considered a dealer-installed option) forced air induction device is going to come with its share of issues as well as fun. I understood that when I bought the car and so should any one planning to purchase one or do such a modification after the purchase.

Once the warranty period is over, I intend will add the 65MM SC drive pulley and lightweight crank pulley. Getting the existing SC drive pulley off is going to be a challenge as it has the tamper proof bolt. There are some postings out there with a few options.

Please let me know if you need any additional information.

 

Which generation of Supercharger do you have?

If it's a first generation, keep an eye out for oil leaks near the shaft on the right side/supercharger side.

If it's a second generation, and you want to keep it for a long time, you might want to look into getting a new and far superior shaft and bearings... especially if you up your boost with the 65mm or smaller pulley.

Another thing to do once your past the vehicle warranty, just so Toyota can't blame it on the S/C, is to swap out your BPV... much improved boost handling!!!

Upgrade your summer oil changes to 10W40 and your winter to 5W40, the thicker oil helps in the supercharger. The seals are not nearly the quality of the ones in your engine, so the thicker the oil the less chance you'll have of leaks. Also make sure you give the car 30+ seconds of cool down as to not allow hot oil to be sitting on your supercharger seals after the car is off.

Despite what goes back and forth on here about lean/rich/AFR's when it comes to changing things on your engine with the supercharger. Here are some actual driver tested facts:
1) you can run a CAI or short ram intake and not throw a CEL or effect your AFR to the point of danger.
2) you can swap out your BPV to a BOV and not throw a CEL or not effect your AFR to the point of danger.
3) you can run the 65mm pulley without a tune and not effect your AFR to the point of danger

Glad to have another S/C tC around!!!

 

bshipman i was really hoping for a point to the VERY long post, i found none.

 

It's done! 65mm pulley installed!
I followed this guys write up on how to....
With the exception of using a Kobalt oil filter removal tool.... which I broke...
I then went with his idea of using the standard oil filter removal tool... and sandpaper (the rough stuff!) I did get a little frustrated with not having the proper way to hold with one hand and wrench the bolt off with the other. So I put the old serpentine bolt to good use. I held the oil filter wrench down with it, run to under the car and I stepped on it with good tension.


I also trusted the guy at Ace Hardware to get me a 3/8x24-1" bolt, grade 8... well he got me something more like 3/8x12-1", grade 8... so I am being gentle until I get the proper one to replace the original piece of $h!t tamper bolt.


Did start her up after I made all my final checks on the belt, leaving tools in the engine bay and are all the nuts and bolts back without any extra's. She turned right over and idled high then slowed back down to just under 1k-rpm.
I haven't driven on it yet, however that's what I'm about to go do.

Tomorrow? DYNO TIME!
I'm going to call it a stage 1 kit, 65mm pulley and replacement BPV....
Next? Inline Air to Water Intercooler!!!
Of course that's after I relocate the battery to the trunk because I need that space!!!

 

Where u going to dyno

 

CarzPerformance in Lakewood, CO
I dyno'd with them last time, so I want to use the same dyno to see the performance difference....

 

For sure let us know how u do tell nate I said what up

 

....plans delayed
Will post when I can....

 

Good luck with 9.5 pulley. I dont wanna sound like im raining on ur parade but, I hardly felt a difference and thats not even the worst part. I installed the 9.5 a week and a half ago, went to start the car up saturday morning and heard the dreaded failing bearing noise. Ive been supercharged for 2 1/2 years now and this is the second supercharger to blow on me. Not to mention My engine, tranny and cat blew all within the past 2 1/2 years of boost . Im returning to stock (NA) as we speak. Ive just had enough of this migrane. It was a fun ride but not worth the headache for the power gained. Hope everything works out for ya bud.

 

The only issue I've had is the first generation s/c seals started failing. Under warranty Toyota replaced it with the second generation of s/c. I've been running on that one for about 8k miles.

I did notice a big difference in both the replaced BPV and the 65mm pulley. Running the new pulley is what I imagine the car would feel like with the stock pulley at sea level. I haven't been running it hard but I haven't seen 9psi on the boost gauge. I do love 3rd gear more and more!!!

 

Third gear is my fave too or fourth ran into that 427 cobra again Friday night it was a laugh anyone know what those cars have power wise

 

Yea, i put around 11k on the 2nd generation s/c (the one with the redesigned shaft) b4 it blew. They def didnt upgrade the bearings for newer s/c's. Couldnt handle a week with the 9.5 pulley. Im not sure if i was getting all 9.5 psi either but when i had the original pulley on there combined with the apr r1 diverter valve i was peaking at 7.6 psi on the dyno much my amazement. Ur probably not gonna see all 9.5psi until u get a raspy header. If u go to nst's website ull see that there tc test car had a megan header and spipe.

 

what do you mean "second supercharger to blow on me. Not to mention My engine, tranny and cat blew" what exactly happened?

 

I did purchase the replacement drive shaft from Gompka, I need to get that in with the new bearings and a grease fitting too.

I do have a full exhaust setup... including raspy header which coryjames hates... it's only bad when it's not fully warmed up and only in 1st/2nd gear. I won't mention the fact that coryjames sounds like it wants to explode, so you really can't hear his exhaust... it's all engine.
