Opticon- 380 ft above sea level
Eric-4200 ft above sea level
Ah ok...makes more sense now, elevation is a killer for sure.

The side by side video is very cool. I think the Opticon avitar wins too, cracks me up every time I see it. Maybe I need a tune for Christmas.

Boost pressure has little to do with strain on engine internals. Cylinder pressures reach over 200psi during the power stroke. So 23psi of air isn't going to damage a damn thing.
It's preignition (detonation) that melts motors. As long as you use high octane fuel, a good intercooler, and don't get rediculous with ignition timing the motor will stay together. If you need more help preventing detonation you can look to methanol injection.
Little motors with tiny turbos like the Sonic have to run much higher boost pressures to get a measured increase in power (less "inches" to pressurize) compared to a large displacement motor. So 20psi really isn't that uncommon.

I dropped your new video in the doubler and synched the launch...

It still looks like I hit 60 while you were at 50, but there is no doubt it would be a different story at the same altitude and ambient temp.

I hope some people realize that when someone says I'm running 25lbs. doesn't mean they are pushing a lot of hp. All depends on the size of the turbo. 20lbs on one turbo, could be like 10lbs on a bigger turbo.
