I have a friend that wants to buy one of these kits for his 13. What can he expect to pay for something like this?
The previous gen GT500 have slowed down with the KB 2.8 vs the 2.3 TVS. Tell your buddy to forego the 2.8, he'll be disappointed.
Agreed, the TVS is capable of making more power than the motor can handle so unless he plans on building his motor it's kinda a waste of money.
The KB 2.8 is a great supercharger. It makes great power and has a great linear torque curve.
Recent customer switched from a TVS and pulleys on E85 at 19 PSI to a Kenne Bell 3.6 (I realize you asked about the 2.8 but I wanted to provide a real world example) Kenne Bell 3.6 at 19 PSI. He picked up four tenths in the quarter mile. Same Boost Pressure but the longer and more linear torque curve makes the difference. As he said, "it pulls like a freight train on the big end, way more than the TVS ever did"
I run a 2.8LC KB (20-21psi) on E85 with the help of Van and Lund... The main difference is exactly what Van had said. The car just pulls long and consistently on the KB... I am extremely happy with my setup and the KB.
