At a 100000 miles:

SRT-4 owner: **** my car is falling apart! The engine is toast the trans is soup, hardly anyting on the inside works any more, etc.

tC owner: Wow, I've drove this thing like I stole it and it has a 100,000 on it and still nothings gone wrong yet. **** it'll prolly go another 100,000 if not 200,000 before I seriously have to worry about it. cool.

 

ahh, but a mere change of the size of the supercharger pulley would make the boost increase and would cost maybe a few hundred buck, switch the pulley back when u have to get it serviced and then noone will know :)

 

sweet, so what, smaller pulley and it gives you more Hp?

 

how does that work or affect the s/c...from my understanding a smaller pulley would make it spin faster ???

And why havent i heard of the Matrix/Corolla owners doing this with their superchargers?

 

Yeah, a smaller pulley makes the sc spin faster, compress more air and make the engine give more power. However, since the ecu add-on that comes with the sc will be tuned with the pulley sold with the sc, you will have to retune the ecu if you change pullies.

 

appearently 1zze-fe Matrix/Corolla owners have tried this out but to no avail. I posted this on another thread and it turns out theyve tried adding a smaller pulley upping the PSI to 9 but only seeing gains of 5HP and an overheating of the air going into the intake.

 

Thanks for the info. I'm reading some info on http://www.2003corolla.org about the pulley issue. I couldn't find any place saying the car was retuned after the pulley, so I dunno...could be that or that the engine just can't handle any more boost, but the corolla is running a 10:1 compression ratio vers 9.6:1

theres the link regarding the pulley issue on the TRD supercharger

look for Blk03Rolla's first post
