flow rates for precision sc34
would anyone happen to know the flow rates for a precision sc34 turbo?
also would this turbo be good to achieve 500whp? thanks guys

As a very general rule of thumb you should be able to get approx 10hp for every 1 lbs/min flowed, but of course this is going to vary with each setup.

LOL, just round that off to 10hp because it's going to vary so much.

Re: (tony1)
If you base it off a turbo compressor map its about right on. Also that came from them since they test and manufactures parts for some of the big turbocharger companies....lol. I would imagine turbo companies don't hire idiots.

There's tons of misinformation out there, doesn't mean they're idiots, just ignorant sometimes.
The amount of power an engine will make with a given amount of airflow is completely dependant on the engine's efficiency.

Re: (tony1)
Its an estimated #. I know and I'm sure they do that different VE's will produce different results, but its nice to have a rule of thumb #. Also since they test the units on test benches, I think they would have some insight.

Re: (Importrev)
10 is an estimated number. 10.86 is a number someone came up with because they didn't understand how it varies with engine efficiency.
You can't test this stuff on a test bench unless your test bench is an engine dyno. lol

Re: (tony1)
Taken from the Garrett tech website:
"What is my mass flow rate? As a very general rule, turbocharged gasoline engines will generate 9.5-10.5 horsepower (as measured at the flywheel) for each lb/min of airflow. So, an engine with a target peak horsepower of 400 Hp will require 36-44 lb/min of airflow to achieve that target. This is just a rough first approximation to help narrow the turbo selection options."
