Re: selecting what size turbo to use for your car!!!!!

This article is flawed. Most of the equations work out, but this equation:
T2 = T1 (P2 ÷ P1)0.283 is flawed.
In the example, we are given:
T2 = 535 (24.7 ÷ 14.7)0.283 = 620 °R
Through order of operations, we have (24.7 / 14.7) = 1.6803
Multiply 1.6803 by 535 = 898.96
Multiply 898.96 by 0.283 = 254.41. Therefore we have T2 = 254.41 which is a far cry from the 620.
Through some research and extensive "Googling" I found this article at http://www.turbobygarrett.com/turbob...o_tech103.html to be easier and more informative than the referenced post.
From one noob to other noobs, good luck.
