Once when I was driving home from Phoenix, I was topping out my car, probably ~132ish and my friend in a Lightning(upgraded supercharger, chip, etc etc.) flew past me like I was standing still!! Gotta love that supercharger whine.
Here they take it seriously...called "Straight Attack"...Skylines and Supras are the preferred weapon of choice for 300+ km an hour runs...haven't witnessed it live yet but hope to soon!
My Pro Drift / Shop Owner Friend told me the serious ones are pushing 800+ horsepower!
I managed to get my Supra up to around 155 mph (the speedo gets up to 180), and it was an n/a with intake and A'Pexi N1 exhaust. I wouldn't have even considered it if i didn't have the suspension set up with KYB struts, Eibach springs, and cusco front and rear strut bars. That really wakes you up when you're half way into a 6 hour drive from LA to the bay area and you left LA at 11:00PM. I swore I saw a UFO too while i was out there....
