noob turbo question...AR????
well i have searched and searched but i cant seem to find anything helpfull about turbo AR.
from what i understand its the ratio between the compresson and the exhaust housing... but then again im not sure.
what is a "good" AR.?
what ratio= fast spool and what ratio=big top end power...or does it even have anything to do with that?
like i said im quite in the dark. any help would be much apreciated, so please keep the flaming and noob accusations to a minimum.

What is an A/R ratio and how is it calculated?:
The A/R in a relationship that is obtained when dividing the interior area of the turbine where the inner walls are found, through the turbine housing radio from the center to the tongue as the illustration indicates.
A/R values are expressed as .35, .47, .68, .84, 1.00, 1.15, etc.
A small A/R indicates a small interior volume in the small turbine and a large A/R indicates a greater volume.
At a minimum A/R the motor's response is produced at small revolutions per minute but at high revolutions we will not achieve an adequate caudal. We should always find a compromise between achieving the lowest response possible and have enough caudal at high revolutions.
ah yes dont i feel like a jack ***!
