I have been gone from the boards for awhile but just wanted to check in. We just finished a simple twin turbo install on an otherwise stock 2010 Auto trans Gen 5, & 65,000 miles with typical results.
Stock it made 355 rwhp at 5400 and now with just 6.2 psi it made 571 rwhp at 5600.
These numbers are indicative of what most customers end up with.
So what about the price? Why are twin turbo kits so much more than simple supercharger installs?
Simple, you get what you pay for and in the case of a twin turbo kit you have the ability of going from a simple 125hp gain all the way to 1300!
Naturally you need a built motor for those crazy numbers but what you will not need is a blower upgrade or a pulley change. What you purchase from day 1 is all you need to grow and build upon forever.
