How much more power or how much more speed if added 525scx2?

The 525 super charged motors or the 525 hp efi motors???

Tomcat did a test with & without water going to an intercooler. I think he said the water only added about 30 more HP. The intercooler lets you either crank the boost up or gives you a greater margin of saftey from detonation which can & will cause engine falure.

When the air fuel mixture is cooled you can be a little more liberal on the timing without the risk of detonation. I would imagine with that in mind you would get more then a 30 hp difference.
