NST Scion tC TRD Supercharger Performance Upgrades


The first thing most people with supercharged cars do to increase power is a pulley upgrade.This is especially true when it comes to the popular Scion tC TRD Supercharger.

Want 20+whp from your TRD SC tC for less than $100? ...


THE CAR & THE PARTS
Owned and piloted by Jeremy and Wendy Helms of Garage1217, our 2006 project tC came to us as a project car that had yet to lose its automotive virginity to performance mods. Having previous experience with other Toyota platforms, Jeremy and NonStopTuning now wanted to transform this quiet little car that could, into a little beast that would!


The plan was simple and Jeremy got to work fast. A TRD Supercharger was acquired and installed in Jeremy's own garage, "Anyone with the right tools and a bit of courage can handle this installation in a day" says the proud owner of our project tC. All the pieces in the kit were properly installed and specs were double checked. The ECU was then re-flashed by Toyota


Next up was the task of adding some go-fast goodies, and this is where NST stepped in to help out. Our 65mm overdrive SC pulley (NST02065) was installed, in less time than it took the local Pizza Shop to deliver our lunch, and boost levels went from 7psi to 9.5psi at redline. While at work, Jeremy decided to throw on his Megan header and S-Pipe for a little extra "bling" and called it a day. The engine remains completely stock otherwise, as no other modifications are necessary for the extra boost levels.

THE RESULTS
Most Scion tCs post numbers in the range of 194-199WHP at the stock boost level of 7psi with the TRD charger. One of the highest WHP supercharged tCs we have seen recently, our project tC posted some very impressive numbers on the dynamometer. Max Power recorded was 231.24 while Max Torque came in at 199.16. Doing the complicated math tells us that our new 65mm SC pulley, along with a header and S-Pipe, has netted us an extra 30+ WHP, while remaining in the efficiency range of the stock engine management and fuel system. Obviously other modifications and higher numbers are possible with extra tuning and fuel management.


THE COST
2006 Scion tC: $16,500TRD
supercharger: $3,000NST
65mm pulley: $95
Pizzas for lunch: $18
231 WHP, 199 Torque... Not too shabby

The Sc pulley is worth every penny + and is a great addition to the TRD SC for your scion tC! I highly recommend it!

Definitely the best $90 I have ever spent on my tC. Thank you NST for offering such a high quality product at a rock bottom price. NST FTW!

I have a 9.5 pulley on my car. Its a huge kick in the parts for the supercharger! It really wakes up the car and makes a huge difference. Well worth every penny!
