1uz V8 Supra - ITB's this is what they should sound like!
http://www.v-eight.com 1uzfe NA 420rwhp @ 9300rpm sure, its nice to whack some ITB's on a stock engine, and get a nice slow throaty burble, but this is where the money is at! Modified engine internals, lightweight rotating assembly, INSTANT throttle response ans a 9500rpm rev cut. this short vid demonstrates short squirts of around 1/4 throttle and about 6500rpm max.
