Re: Strappin' the Intercooler - '87 %KCSQT

["Newman,Lawrence C." <lcn@mitre.org>]

If you run that kind of pressure, you may have to roll a lip on the
intercooler pipe if one isn't there already.  I've never done it but I
have heard it is necessary for high pressures.  Even with the lip, I once
blew one off my intake plenum at 15psi (I believe it peaks at 15psi.)
Thats what my gauge reads but spikes could put it higher.  That may be
what's happening to you.
