I have been reading and performing the calculations as listed in Corky Bell's Maximum Boost.
I thought some of you might enjoy following along with me as I perform the necessary calculations to Borg-ify my MKII Supra and hit the 200mph mark (someday). Or if you're just curious about WTF is going on inside your engine, or curious about engine efficiency and other curious facts.
I will post the pictures of my calculations so that you too can understand what actually happens on the inside. I will eventually follow up and edit this post so that it contains all the complete calculations (and the post below this one will have them as I go along).
I will ALSO post up AMAZINGLY AWESOME gumdrops of info-tainment wisdom. (Ok, so it's really hard facts as put out by Corky, I just happen to find them AMAZINGLY insightful AND entertaining.)
Let the madness begin.
**Some of these calculations are using MY VARIABLES... like 18psi (as a working pressure) etc etc. You CAN use your own... figure it out or GTFO.
Also you'll see stock figures in the center-ish, and my upped-redline numbers off to the left...(margins)
CLICK PICTURES FOR HUGE VERSION
Pressure Ratio, Flow Rates/Airflow
Flow Rate by RPM chart I made up (NA Airflow is the tiny number above).
*This Chart WILL CHANGE depending on your turbocharger's compressor map, and the slew of no less than FOUR variables. That is why the Middle Section is INCOMPLETE (right now) I need to consult the Borg-Warner compressor maps... (compressor & turbine housing AR's, compressor and turbine wheel AR's, Spool Valve, Timing, AFR, Fuel, Temperature, Exhaust size etc etc.)
S472 Compressor Flow Map.... needed to figure out if it will fit my needs.
I have learned this. Figure out your Application/NEED (where you want power), Do the Math, then pick the Turbo. Sounds straightforward, because it is. So... this S472 May NOT be the right one for me... it's for example... and what I'm comparing against for now.
Turbo Flow Rate Calculations... and the beginnings of calculating the volume of a radius'd cylinder... (Can Anyone Help with this shit? like calculating the volume of a cylinder (u-bend) given a certain radius?)
