    Should I upgrade my injectors?

    I dynoed my car at 355 @ 17psi and my afr was in the 10s. I think I can squeeze a bit more power at 17psi boost and still keep the afr in check below 12.0.

    Should I upgrade my injectors?

    80% duty cycle is recommended which gives you room for spikes and what not unless you brave enough to hit 100% duty cycle. I know someone who ran his 440 to 90% duty cycle and he had boost spikes and guest what. :nono:

    1jz single turbo dyno

    I finally got to dyno my car after going single turbo. This was done on a Mustang dyno (no inflated numbers here) in this weekend meet in Tampa. The AFR was super rich not even worth showing the chart. Not bad though I think considering my very first street tune with the SAFC. I can get more I...

    Valve Cover Venting

    The stock 1-way bleeder valve on the intake cam cover is known to fail. The recommended replacement is to use 2JZ PCV valve.

    For all you NA tach users...

    I don't see why it won't since the 1jz and 2jz use the same igniter. How's the 2j man and when we're going to OSW? HAHAHA, yota beat me to it.

    Fuel Upgrade

    I want to get close to 500 maybe 480rwhp with the 540cc around 19-20 psi of boost. Or is that running too close duty cycle with these injectors? How do you calculate these things?

    Fuel Upgrade

    That's good to know. Let me know how this works out for you. I'm hearing lots of pros and cons with the 650 being out of the range of the safc. I may just get the 540cc for now and see how it goes. Thanks for the replies guys.

    Fuel Upgrade

    About 18-20psi. I heard a lot in sf with this setup and even running with 680cc and some with 720cc with good success. I do agree that will have to pull lots of fuel and get the low throttle tune correctly or it will be fouling out the plugs left and right. If I can get close to around 500rwhp...

    Fuel Upgrade

    Are you running the same setup. What's your fp pressure set at how much fuel did you pull at upper rpm range, just curious... thanks.

    Fuel Upgrade

    I'm thinking of getting a sard 650cc direct fit injectors. I already have a walbro pump and just bought aero afr. Has anyone run this fuel setup and also like to know if you were able to control the fuel and tune it with a SAFC? Thanks.
