Hello Craig,



I would recommend the Stage 2 Boost Cooler™ kit that reads manifold boost pressure to proportionally inject more or less water-methanol. This is proven to be the best way to get the most horsepower over the widest range of conditions. It is also the best kit for a daily driver, as you will be injecting the maximum possible over the widest range of conditions. With the Stage 1, you need to inject the minimum amount of fluid so that it won’t bog at whatever rpm and boost you start at – everything beyond that will be injecting less than optimal. The Stage 2 is also very easy to adjust if you change other things in your engine setup in the future.



The MAF based kits are usually used on positive displacement superchargers like Eatons, whereas your TRD/Vortech supercharger is centrifugal, and the standard #20010 kit works better with that type of forced induction.



The cooling effect will definitely help your performance and consistency, especially without an intercooler. Temperature drops of 60 to 100 degrees F are not uncommon. The other huge benefit to running water methanol is octane improvement. With 91 pump gas and 50/50 water-methanol, it is roughly equivalent to 116 race gas. This allows you a number of options. You can run with cheaper low grade gas, you can advance the ignition timing for more performance and you can increase the boost, or some combination of all three. You will likely be able to slightly lean the fuel delivery for more performance as well.



At your performance level now, I would suggest a 225 nozzle, and I would include a 375 nozzle for your future setup.



Hope this answers your questions – let me know if you have more or are ready to order.



Sincerely,

Greg Dunn
