Can you get a wastegate with a larger can diameter? A larger can means the spring is stronger for a given PSI setting, and fights the wastegate blowing open better. And, a wastegate can that goes from cracking open to fully extended over fewer PSI (e.g. 5-8 psi instead of 5-15 psi), will have more "feedback gain" and give you a flatter boost curve.

On the bench it cracks at 5psi and is fully extended by 15psi. Best case scenario I get a rise 0-6psi, plateau, rise 6-8.5psi and plateau. Is there any reason I can't run an MBC prior to the EBC solenoid to produce a stable WG base? So I'd tune the manual boost controller to 10psi without the EBC in the loop. Then add in the EBC between the MBC and the actuator. _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower
