Hmm... My non-intercooled 85 Buick GN ran 14PSI boost stock... the 86/87's
went to 17-18 PSI if conditions were favorable (intercooled) and the water
to air intercooled Syclone/Typhoon only ran 15 or so PSI...
The problem with a water to air intercooled turbo on MOST cars is they use
the engines own coolant... this means it's not cooler than 180 degrees once
the engine is up to temp... The Syclone.Typhoon used antifreez, but it was
a seperate circuit with it's own pump and mini radiator... It's problem was
the pump wasn't triggerred by the ECM until the temps got way up.
