to eBay or not to eBay?

This is a great point, and probably the best argument of all for water injection

Oh - and use Iridium plugs, they are the ONLY plugs that last 10k+ in these motors

Depending on whether he's talking about water temp's spiking or air temps spiking I can def support it.

The cooling that water provides to the rotor housing will def take significant stress off the other parts of your cooling system, that's a very good thing Your water temps will also really benefit from having good oil cooling (dual) that are properly ducted. Also make sure that (both) your radiator fans are working properly!!


As for Air Temps, once the water/meth starts spraying you can def expect to see your temps plummet. With my VMIC setup I'll normall see intake air temps of about 8-10 degrees (Celsius) above ambient air while cruising around. Once the A/I starts spraying (and you're getting on it!) that temp will drop even closer to the ambient temperature. Each pulse in normal driving will normally drop the temperature a degree or two until it's down to 2-3 degrees above ambient.

Colder air = denser air. Denser air = more oxygen. More oxygen = more power.
