[s-cars] Wastegate Musings

[Scott Munger]

Those of you who are boosting over 23PSI with a greater than stock CFM
turbo, what wastegate setup are you running?

Even with the factory spring cranked 5 full turns, my boost gauge was
suggesting I'm prematurely bleeding boost around 22-24PSI with the RS2
Turbo.  I swapped in a 1.8 BAR spring and boost comes on faster and doesn't
appear to bleed.  Readings are about 27-28 PSI.

With a 1.8 BAR spring, the risks are that the ECU cannot control boost via
the WGFV below 11.6 PSI/, correct?  With a boost gauge and a driver who is
paying attention, this risk is tolerable.  Any other side effects?

Thanks,
