Unfortunately, when you do this on a public road, you're endangering not only yourself but those around you.
I don't see why it's so hard to go to a sanctioned race track and do it...

You need to take some 8th grade science classes buddy
Every substance in the universe can boil and freeze. They all just vary in temperature.

When it knocked, it sounded like a hose blew loose, because the boost dropped too (I could see it out of the corner of my eye), and power stuttered for a brief moment and then all resumed as normal. We're talking not even a second. I am running 15lbs of boost, and using the Intense Stage 3 kit.
I still continued to push it. And stopped just a little over 140mph, and took a picture. I was hoping to hit 145-150mph, and I know it's possible, but it is just too hot here in Phoenix. After my run I pulled over to look under the hood, and my intercooler fluid was BOILING! That is probably why I had knock, I doubt the intercooler works at all with boiling liquid running through it.
Should I change the fluid out to Red Line Water Wetter? That should be able to withstand more heat right?
I was running it hard tonight, so I know the supercharger and all the coolant was pretty hot to begin. Not to mention it's still 103* outside at 11pm.
Here's the pic I took. Sorry for the blur. I was using my camera-phone, and driving 140+mph so I needed to look at the road.

lower you air intake temps (run at night or wrap your intake, lower intercooler temps) or retard your timing at high IAT.. it will run a tiny bit slower but no crazy knock. I'd suggest doing both actually...
also note our cars knock all the time and we dont hear it and it will reduce the lifetime. you should be ******* freaking out about audiable knock...

Although So-Cal has a 240+ mph cobalt that they raced at Bonnevile but it is a 800hp 2.2L Turbo with an SS body.

Yea AZ has some nice roads ut there are streaches of interstate that you honestly put your lif on the line driving on. OR had... back in '05 I drove down there helping some guys move with trucks and a trailer adn the lead truck broke an axle clean off. This was Feb-march timeframe too. Was raining there really hard adn it was really cold for AZ. Come to find out the pothole he ran over was over a foot deep and caused a semi to jackknife.
Oh and btw, running that hard with it being that hot was stupid. I'd be taking the head and replacing the gasket if I were you.
