denso 660 injectors?
what is the max whp on these injectors for the evo
at 100% duty cycle?
and 85%which is considered to be the max duty you want to see from the injectors.
Thank you

You should check out http://www.boost-solutions.com/ they have a chart that will tell you the supported HP. This should give you a safe number for the 85%-90% duty cycle. I know they you don't want to go much over that becuase you can cause detonation.
I hope this helps

I posted a thread not too long ago about my findings with the stock injectors with very minor mods (S-AFC, Air Filter, Exhaust) with boost spiking at 21psi its hitting 99.9% Take it for what it is, but its definitely a good idea to upgrade (and adjust your tuning accordingly) but upgrade your fuel pump too.. I can't tell you for certain how much horsepower that equates to, but its basically the Buschur racing stage 1 setup, without the boost controller, boost spikes with the stock solenoid to 21psi then settles to 16.5psi (as you would expect from stock) with a manual boost controller, set it for 19psi and the duty cycle would hover around 90% which is still not much wiggle room.. Any more boost or a need for more fuel would definitely imply the need for the upgrade.
