I'm thinking about running my car in an autocross class that doesn't permit a boost controller. If I have a full 3" turboback, open element filter, I/C piping and SAFC, would I have to worry about overboost/spiking? How much boost would I see at peak and taper? Would this setup run into fuel cut problems without something to address that?

Thanks.

 

Rich, try and contact another evom member, badbus. He's running a similiar setup and had the same problems at first with boost spikes. He had just gotten a BR turboback put in with a S-AFC2and they found boost spikes. But he got it smoothed out, he'll probably have more details. He does a lot of autocrossing and has to run a similiar setup without a boost controller.
