Dyno results will be up a little later this week. While this manifold does lose a little bit of low-mid range power on a naturally aspirated car, it gains as much as 58RWHP from 7000 and up! It smooths out the whole powerband, and when used with nitrous (like we did) it's a huge increase! We have plenty of before/after testing - as well as some track footage to share with you.
Let's start off with the JLT intake, which fits perfectly... like it was made for it. We tested the Airaid intake, which also fits, but you have to trim a half inch off of each side of the coupler to the throttle body. The C&L intake fits. The Steeda works with the 2010 steeda elbow. We decided to use the JLT plastic intake for all of our testing because it seems to fit the best and we loved the horsepower/torque results!
We went to the track again today with our 2011 Automatic GT with the NEW JLT plastic cold air intake and Boss Intake manifold... and here's how we did. Beautiful day, about 50 degrees, partly cloudy... track was prepped really ****ty, but it is what it is...
