Optimal EGT for a Promax 300

[Toffen]

Hi!

I have bought Gaffrig Merc EGT gauges, and I would be pleased to know the limit for safe WOT (EGT reading).

I have mounted SVS Intake + High Flow Reed Plate. I have not modified the ECU yet. According to Brucato, the map sensor should adjust to the increased airflow pulling more gas. Should give 25 hp.

Also blueprinted my EFI injectors. They were 17% off, and now they are all excellent and within 0,4% tolerance. Should give 5 hp.

Will test next week when I hit the water after 6 months winter!

Cheers, Toffen G - Norway

Unfortunately, it depends on your gauge. You will have to find the safe limit first by reading pistons or plugs. Once you know it, you can look at the temperature reading on the pyro. Then you know when things get dangerous the next thing around.
