I don't quite have 600rwhp....well maybe on the 200 shot. My best dyno was 535rwhp on the 150 shot with 800 psi bottle pressure (best NA is 383rwhp). I have ET streets at all times on my car so it is not really scary. I can nail my car off of a stoplight and it will barely spin the tires NA on concrete. On asphalt I have to pedal it a little before I floor it. On the bottle it is a different story. I get scared in first gear. The car is so violent in first gear that if it hooks (will dead hook from 10 mph on concrete) it kind of makes you get butterflys in your stomach cause of the acceleration. The pull through second and third is nice but def not as scary as first gear. My car will not spin the tires in 2nd gear from a roll though but at 30 mph in first on asphault with the 100-200 shot it will smoke the tires and instantly redline. On concrete I have pulled the front tires from a 10 mph roll when it hooked and man that felt awesome (you can tell when you pull the tires cause when it comes down it shakes the stearing wheel and you can also hear the suspension bottom out). My car is all low end/midrange.

I did ride in a 835rwhp (32psi T88) supra before and it was amazing how much it pulled up top. We went from 60-140mph in no time. However, the bottom end range was weak because everytime he got on it it would spim once boost kicked in.

Rich, I think that last sentence goes very well with your avatar. As for me, I figure you have to have just enough HP to give yourself a little scare and a big smile once in a while. Otherwise what's the point?

 

I've been in several cars that make 600+ rwhp. On the street its not really that much different than ~450rwhp until you really start to break the law in a big way.
