turbo at 6 miles up works good ? I'd love to see the compressor maps at that altitude.

 

Carbon fiber was first used by NASA then the aerospace industry. Most small planes that are built now are made from carbon fiber.

Since the air is thinner, wouldn't a turbo be better? I'm just guessing.

 

I dunno if it works better or not. I do know that a motor like that will only make like 300 hp when its up at a high altitude hah. Not 300 but its deff far off from what it would be at sea level

 

you do realize that this is where turbos were first used right? so ww2 fighter planes could make enough hp to fight it out at higher altitudes without stalling...



I think that the turbos will work just fine on a small passenger bird...

 

weeeeird.. I guess I just dont see carbon fiber as being as durable as it really is. lol

yes im aware. As were superchargers. But i want to see a compressor map of that altitude thats all...

A turbo with a wastegate sprung at 10 psi will make 10 psi at sea level, and 20 psi at 20,000 feet. The lbs/min flow of the turbo will be the same, given the same engine(altitude as the only variable), but the speed of the turbine itself will be higher at the higher altitude because there will be a greater pressure differential between the inlet and outlet sides of the compressor.



And on the carbon fiber thing, carbon fiber was developed for aircraft applications. The bullshit that you see on cars(short of F1/indy/mercedes SLR), is nowhere near the capabilities of carbon fiber. A great deal of the strength of carbon fiber lies in the resin used, and typical auto parts use the cheapest **** resin available. Boat building resins are far from the advanced resins used in the aerospace industry.

Like you know **** about that anyawys. GO back to reading your magazines ****** ricer.

 

The 2 biggest reasons for having a turbo-charged engine in an airplane:



1. High altitude engine effeciency.



2. Cabin Pressurization. Air is bled off the turbo and into the cabin so you can fly at high altitude and not have to be on the o2 bottle.



I used to work on Piper Malibu Mirages back when they first came out. They sent all the techs to Garret school.
