Did you input the dataset for the RA? If so, what kind of results did you get?

I don't know enough about the actual stock #'s..

I figured someone with a lot of knowledge like Joe(sillypuddy) or Rock or someone that knows all the numbers off hand.

 

i did just do the pick a turbo for an engine..


MAKE TYPE HP Rating TURBINE HSG A/R
Garrett GT25 290 0.63

278.57487959321304 BHP
25.64003191775933 lb/min Air flow.


thats on 6200rpm Redline/2400cc/10 psi of boost.


but as for the turbo power?

here's the numbers one would need.

# Bore: Cylinder diameter in inches.
# Stroke: Engine stroke in inches.
# Number of cylinders: Number of cylinders.
# R.P.M: Engine revolutions per minute.
# Ambient air temp: Air temperature of of the day, in degrees Centigrade. To convert Fahrenheit to Centigrade, C = (5 \ 9) * (F - 32)
# Engine VE: Engine Volumetric Efficiency in percent. VE changes with engine RPM, a engine at wide open throttle at 3000rpm could have a VE of 90% and at 6000 rpm 60%. This is a rough guide. At maximum RPM modified engines may have a better VE, e.g.: average overhead valve engines 45% to 75%, overhead cam twin valve 65% to 80%, four valves per cylinder 75% to 90%.
# Boost Pressure: Boost pressure in pounds per square inch.
# Compressor efficiency: Turbocharger compressor efficiency in percent. average turbocharger compressor efficiency 60% to 70%.
# Intercooler Temp: Temperature of cooling medium for intercooler in Centigrade.
# Intercooler efficiency: Intercooler efficiency in percent. Average intercooler efficiency 70% to 75%.
