The problems came with the bearings in the shaft only. After i had purchased this kit ( i was the third owner), it already had just the bearings in the housing replaced and the shaft was still stock. Now this s/c was used at the track by both of the previous owners and eventually, as would probably any with that kinda use, it gave out. I was fortunate enough to have the original owner come out and replace them for me after i first bought the kit and he had said that they were a higher speed rating and ceramic, and it turned out it needed a higher speed rating according to my mechanic who is installing the new ones in the shaft before i sell it. I'm sure the pulley played a part in the bearings going out quicker, but mainly i think it was the use/stress put on it from some track time.

 

Had my blower on since October 21, 2005(one of the first on the East coast I believe) and I haven't had any problems in over 30,000 miles other than the s/c bracket which was replaced under warranty.

 

Ah ok that makes sense, thanks for the info!

 

Can you still use regular unleaded gas when going supercharged and how much of a gain would you get with a auto? I havnt seen a decent video online with someone flooring it with just only a supercharger from 0 - 60.

 

A supercharger will add more heat into the engine and the higher octane will help control the heat so your engine does not detonate. Detonation or "knocking" is caused by heat or lack of fuel and it can distroy your engine if left untreated.
Detonation sometimes is silent, so even though you do not hear any knocking sounds, your engine still might be detonationing. This detonation will burn a hole in your pistons or even cause your rings inside of the engine to fail.

there's a couple of links to help you learn

 

Yup you're definitely going to want to run higher octane fuel with any F/I car.

I'm of two minds on the S/C- it sounds like it would be a lot of fun, and would fulfill my want for a faster, boosted car without actually trading in my car, which isn't really an option. It still seems (so far) that most people are not having any problems, but for those who do, the problems tend to be really, really bad. Maybe I'm just being overly cautious?

 

Well I realized that most of the people who have posted good things have 2005 or 2006 tC's, so that is definitely good news for me Lets hear from some more supercharged people!

 

If you want to go s/c do it..but just don't go around and upgrading everything. Just upgrade to 110 valve, K&N filter and take out that trap thing inside the air box. you will be fine with those upgrades. If you want to upgrade the pulley you are your own. Some people have had problems and some haven't, but that's how it goes for everything.

 

i am thinking of s/cing my auto 07 and wanted to know what knda power gains i would be looking at. does it make enough power difference to even tell or be worth the money?

i am either gonna turbo or s/c. i am not a speed junky but would like some extra power. with the supercharger would i need headers or to upgrade to a catback exhaust rather than the axleback that i have?

 

I definitely agree, I don't think I would want to mess with the boost pulley at all. Too many risks. The BPV, filter, and HC trap removal, definitely. I still like the idea of the catch can as well, to catch the oil vapors, and to (when set up properly) vent the crankcase to keep it from being pressurized under boost. I've seen a few theories thrown about as to that being a reason for supercharger failure.


That's a good question, 05-RS1 is the only person I've seen post up dynos of a supercharged, automatic tC (and I've looked.) I'd actually love to see some dynos from other supercharged automatic tC's as well.

I'd avoid the headers if you want to keep the warranty, they'll void it for using headers. As for the exhaust, I'd definitely upgrade to a cat-back, as from what I read the supercharger really benefits from a free-flowing exhaust. Heck, I wouldn't mind upgrading from my Skunk2 to Ptuning's 3 inch exhaust, from their dyno's that would be good for another 10hp for a supercharged setup. That exhaust is expensive though...

 

i've been boosted for about 6 months and i put something like 7k on the car. I have catback and 9.5psi pulley and aftermarket bov. I hit redline many times daily and haven't had any problems. Although i do have to add a quart of oil every few weeks.

 

i had my sc for about 14months now no problems, self installed has alot of mods on it. still no problem. just remember 1 thing tho the more boost = to faster wear on the charger itself.

 

I've had the s/c for about a year and a half and about 30k miles. It started leaking oil earlier this year from the shaft. I had the seal replaced and it was running great. About a month ago it happened again. I had it replaced again, and now a month later I have the same problem. Don't know what to do now, the s/c has been a real headache as of late.

 

I had mine for 2 1/2 months now but brought mine USED(3000 miles) so far so good. i really think it depends on the installer, mine made sure that everything was done rite, he even contacts me to make sure its running fine. he previously S/Ced 3 others so look for experience, if its a first or second timer i would not recommend doing it. and also yes gas will be a pain in the @$$ my only downside. and be sure to break it in (dont push it for like 500 or so miles).

 

its like an extra 2 bucks for premium. get over it. i am!

 

Ive been supercharged now for about 3k miles.

I bought it used with around 8k miles

I Installed it with the NST 9.5 pully, CAI, Aem Boost, Aem Uego. Fordge 007 bpv. Wrapped headers


Runs Perfect. 11.6 AFR at wot
I check my oil everytime i fill up and every morning before driving.. I have not lost ANY oil.

I have no oil leaks..

No bearing failure as of yet!


With the mods i have its ALOT Faster, Pulls alot harder, And deff wastes more gas!

I DO not run mobile syntetic. I run there clean 5000 oil and have never had any engine problems!


If u could do it again, I would!


And just for some honda love, Best friend has a 08 si.. from a 40 roll to 100. i get about 8 car lengths!

Thats all , Kthnx BYE

 

5500 miles now, installed at 20000 on my 2006 tC. No issues, runs VERY strong, I beat the heck out of it all the time (ALL the time) and shes taking it well. I run RedLine 10w30 synthetic oul.

 

I have a 2006 scion TC with 21500 miles, almost 10000 (9831) mi. of which are on my all stock (as it came out of box) S/C. I have only had one problem. The air box (stock part) clamp keeps popping open. I had the air box replaced under warranty and the new box is even worse then the 1st.



I love the extra power. I am getting 19 - 22 mi/gal. which hurts a bit now but such is life. I run only high octane gas, check the oil at every fill up (and put the stupid clamp back on.) I want to go to a fresh air/cold air/forced air(?) intake set up as soon as the drive train warranty has run out (I'm very paranoid about voiding the warranty). This will solve the air box clamp problem and hopefully add some power too. Please give suggestions on this air box idea if you have experience in this area. (pictures would be nice too.) I have also added the TRD muffler ("Cat back" I think you would say.) I am thinking about a adding an bpv as I hear people saying the provided one sucks (How/Why?.) I'm not totally up on this car stuff but love to drive my TC Fast (okay faster'ish) and am learning tons from this forum. Keep it coming and thank you!

 

I put a screw through my box to keep it shut. Both of my clamps broke, so this was my solution. Ghetto, yes, but effective.

 

Thanks for the replies...I thought this thread was dead

After some thinking, I have decided to focus on paying off the car before I do anything "big" like F/I to my car. To me anyways, it doesn't make much sense to add a mod as expensive as the S/C, when I'm still making a payment! (the mods I currently have weren't that costly, and I definitely don't regret them.)

I'm still interested in the supercharger, and may install it after the car is 100% paid off. I will see how I feel then, I may also trade up to a car that is faster stock (as much as I like the tC.)

I'm glad to see all the feedback here though, I hope it continues to grow, as I know there are a lot of others out there who have been wondering the same thing that I did.
