Running vortech plastic bypass valve with fmic

97blackgt · Feb 21, 2010

Wondering if i can use the stock bypass valve with a fmic.

Ive got a cxracing intercooler, vortech v2, 3.60 pulley, and i dont plan on running more than 10 PSI.
Im actually looking to run around 7-8 PSI, but i dont know if i can use the stock BPV or if i need to upgrade to a BOV.

I currently have stock MAF and 19 lb injectors, and will be using the FMU.

Thanks

19lb injectors are not going to work out too well that is going to limit you a lot.. best thing to do with s/c and t/c is to always supply more than enough fuel i'd recommend running 42lb but you can run something a little lower. the stock bpv will be fine

id highly recommend upping the injector size as well. a lot of tuners dont even like tuning cars past like 80% of the injector duty cycle anyway, which id be willing to be those injectors would be about maxed out.

and you dont completely have to change you stock bpv, but if it were me I would. look into the vortech mini race bypass valve.

You need injectors, fuel pump and upgrade the plastic POS bypass valve... They are not good after 7-8 psi anyhow... It might leak boost...

they are fine to well past 16 lbs @ 1200cfm. been there done that

they are rated in cfm not backpressure
