png godzilla........ the boost cooler variable controller allows you to run a larger nozzle (I assume Cooling mist is similar), without ignition breakdown at low revs/boost. The symptons you described earlier sound like too much water too early in the rev/boost curve. This is the difficulty with on/off style systems. The variable controller limits the amount of water being injected at lower boosts, which stops this problem, and then increases the amount of water as boost increase. Boost Cooler also have a MAF system which can be plugged in to most 0-5v airflow meters. This is even better than running off boost pressure as it is actually using the amount of air passing through the engine and adding the correct amount of water accordingly. Another advantage of Boost Cooler is the nozzle design, we are yet to have a reprt of a blocked Nozzle. They are a dual chamber nozzle which gives incredible atomisation. We are running an extra 8 degrees of timing in my race car......would never look back now. Mark.

It is still better to use an intercooler, howver - you do not need to go to a big front mount. We tested the same kit on our circuit car with no intercooler, and found that on the longer straights, temps were well controlled, but on tighter, on/off throttle situations, and on partial throttle where you are not using much/any boost, the water alone was not able to give a consistant inlet temp. We have just installed a new intercooler - not huge, and already we have seen lower intake temps and higher HP figures on the dyno. Mafia - the pic of the contol module shows you having both dials set at the same amount (approx 5psi)..... is this how you are running the system in the car? You should have the full PSI set at about 14psi in your application (assuming you are running 18psi)...this will then allow you to run a larger nozzle to add more water/meth at the top end. Mark.

Thanks Mafia for the good words. We have had a great deal of success with the Boost Cooler kits on various different cars, including Supercharged and Naturally aspirated cars. We recently supplied PWR with a kit to trial on their new LS2 supercharger kit.......they were very happy with the results are now looking at buying more kits to supply to their customers.
