Default Re: 2008 STi Port Injection

Hi Richard

Based on the calculation from Jeff's website, the 5 x 0.4mm nozzles are gonna be serious overkill for my setup since i'm running 4 x 560cc injectors, running 18psi and injecting water at the moment.
I get a calculated value of about 370ccs, which is just about the flow for a single 0.7mm nozzle.
BTW, based on the the same calculation, 1000cc injectors and about 25psi gets me 660ccs, which is still too big for the 5 x 0.4mm nozzles.
The big turbo and 1000cc injectors are some way down the road, so what should I do for the moment? Run all 5 x 0.4mm but use some kind of restrictor to keep the flow down? Or seal the port injection for now and use only the post I/C injector?
I've got the following nozzles
0.4mm with 4 scroll insert
0.8mm
0.9mm
1.0mm

Thanks!

Cheers
Dennis
