they run like 74 psi of boost.


theyd dyno the same on the moon.

Altitude will still affect turbos because of air density. Turbos will be working harder to achieve same boost levels. You see a lot of guys, with huge turbo's in these challenges struggling to get the turbo's spooled up, whereas at sea level, they'd probably be fine.

If you are someone who lives close to sea level and you are talking to a guy on a forum who lives in Denver, the same turbo isn’t going to perform the same. Being 5,000 feet lower in elevation than the guy in Denver means the turbo will be spinning roughly 5 to 10 percent slower for the same power. That may or may not seem like a lot, but it may result in the same amount of boost coming in 200, 300 or even 400 rpm later. When cruising on the freeway (low RPMs) or taking off with a trailer hooked up, that’s a huge difference! To get the performance he is getting, you may need to step down one or even two sizes just because of the altitude of your location.

struggle to get it spooled up?

they are brake boosting to a million pounds of boost at the line.

who cares if it takes them a month to build boost at that point :rofl:


it's seriously negligible for these guys...
