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

the SC34 will flow about 54-55 lbs/min max'd out, which equates out to just under 800 cfm

 

is that a good thing or bad? since you mentioned it would only flow that maxx'd out.

 

Its not good or bad, its the flow rates that you asked for.

 

Good for about 550hp. Nice turbo....

 

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.

 

When I spoke to forcedinductions they said its 1lbs/min = 10.86hp.

 

thanks guys. so i could make the amount of power i want.

this is going on a b16 with ramhorn manifold 3indp and exhaust

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

 

lol, or just round it to 10 because there is no correct answer. Whoever came up with 10.86hp per lb/min of airflow is full of ****...

 

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.

 

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.

 

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

 

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."

 

I'm sure the # is based on a median. Plus they have an engine dyno as well...lol.
