i personally think that test doesnt prove anything. no i dont use an Ebay intercooler as I dont drive a car, but who drives around on 40 lbs of boost? who drives on anything realistically over 20lbs or so? you dont need that much for the street, and if you want more you can up it, but id say the average turbo daily is about 7-8 or 9-11 lbs IMO
