The GS looks and sounds awesome. Love the video! What is the fastest you've taken it so far? Seems like you didn't want to go much past 120 in the vid.

I can first hand testify that this car is a beast!! Jeff is a nut having done all this work to a motor with only 28K miles on it. To think he is going to be ditching it too already!! truly an auto enthusiast.

Nah, I just shut down at 120mph. I was driving with 1 hand and not 100% attention since I was holding the camera with the other hand lol. I topped out 4th gear...didn't even go into 5th gear at all. I can take the car up to about 150mph or so very easily if I wanted

Sorry, didn't realize you were only in 4th. That makes the car much more desirable and respectable that you can achieve higher speeds than 120mph. Awesome car and great vid man! Keep up the great work!

One last thing is that 400 at the crank? If so, what does that translate to at the wheels? 340WHP?

I saw your other thread when you were installing your turbos and now I get to see your GS all grown up!! I'm so proud! lol

Your car is wicked fast! Wish I could hit 120mph like that. Your car is a monster in all aspects!
