This is essential in any FI system, as you can be sure that a percentage of customers will have some sort of IC related failure (pump, electric, kinked hose or lack of coolant) during the course of a cars life, and if this is not taken into consideration you will have a massive amount of very frustrated customers with blown engines.
Wow thanks for the info! Great to know there is a large margin of error. So it would be perfectly safe to run the VT1 @ 5PSI, per se?

Car will always be leaving a temperature controlled garage so no issues there, however return trip I could be facing a cold start up.

Looking at the Vortech warranty page it appears to be an issue (voids warranty). Not sure if this is applicable in the VT-535/575 application.

"Subjecting any Vortech supercharger to a cold start-up condition (below 25 F) without the use of an engine block heater/aftermarket engine blanket."
Awesome question. In my area, temperatures range from -30C to +35C (-22F-95F). Can you comment on this, ESS?

Thanks!
