stock flow rate?

Post by jefferson »

I have been reading the series in Subie Sport about turbos and boost control.

The part about roughly figuring what horsepower your turbo can support is interesting.

Does anyone know the flow rate of the stock VF11 in lbs/min?

Something would seem to be off somewhere. I used an internet conversion site and got 47 lbs/min. which if you take the one rough calculation the stock turbo would support around 470 horse. I know that is wrong so either the 381 is off or the conversion site missed. I did use carbon dioxide as that was as close to air as I could find in their choices.

if we take the density of air to be 0.075 lb per cubic feet that gives us 381 cf *0.075 lb/cf or approx 28.6 lbs or 28.6 lb/min of flow..

Thanks a bunch. That is the info I was looking for, but wasn't able to find the right place to look it up or convert.
