Just wondering if there is any rule of thumb concerning fuel pump capacity and pressure relative to the size of inducer or some other way of calculating it. We have a turbo and are trying to round up the other necessary pieces.

Spit out some numbers for us and we'll come up with something....Comp inducer/exducer sizes, trim etc..this will give us an idea of the mass flow and we can go from there..!
John can probably do the calcs in his head...
Cheers,
Smithy.

Hi If we work on a maximum mass flow of air at the rate of 12 lbs/square inch of inducer /minute and a 60:1 overall air/fuel ratio , then we need 12 lbs of fuel per hour per square inch of inducer area A 3" inducer of 7 sq ins will flow say 84 lbs of air per minute ( 1.4 lbs/second), and will need around 84 lbs of fuel per hour or 1.4 lbs/minute , or ~800 ml/min Checkout some "Rules of Thumb" here jetandturbineowners.proboards.com/thread/680/diy-turbinesCheers John |

Good enough i guess our numbers will be about the same as rackets example. Also what kind of injectors are recommended?

Rackets numbers are just out line, what would help is if you could post the type of turbo and dimensions of your turbo, compressor inlet and exduecer etc, do you know the ar trim of the unit
