Timing with SC

SteveK · 05-01-2004, 02:33 PM

I know that there are many companies we can go through to get the timing retarded.

I have Powerdyne and with 24lb injector and 255lph fuel pump on my 98 GT(stock), I am not leaning out too much according to my A/F gauges(left & right banks). Mine is rated at 8psi, but I know that Powerdyne does not push the power it is supposed to(which I am ok with).
So I did not retard the timing.

Have you guys run into something similar?

Thanks,

I hope with those 24lb injectors your using a FMU because if your using a cheap A/F meter using the stock oxygen sensors your going to pop a head gasket or blow a piston. You need at least 36lb injectors even at 6psi to be safe at WOT. I would just go with 42lb and that way your ready for anything in boost. Max. timing at 6+psi should be at 19-21 degrees.

Thanks for the reply.
Yes, I am using FMU. With it, I am actually on a rich side. But with the stock O2 sensor, beign what it is I agree.

19-21 degrees total was what I was hoping to hear.

Again, thanks.
