I'm dealing with bit of a cooling situation. I don't want to run a by-pass for the pump when the Roadster is warming-up. It would clutter up the look of the engine more than it already is. I think I have two options: 1. Run a restrictor plate: Cost is $7.95. The effectiveness is questionable. 2. I could drill some holes in the thermostat. Cost is $0.00, but I'm not sure what size holes to drill, or the effects. Please let me know what you think is the best way to go. However not running some kind of restriction to slow the flow through the radiator isn't an option.
