    Why not use an intercooler along with meth injection?

      because joel just said he didn't want to fit an IC........

      and AI alone has some advantages over running both together

      there are some hardcore fanatics of AI in the rotary world....with unbelievable results

      for instance, on your typical 13b setup with pump gas alone, you are looking at around 15-17psi being your safe ceiling................with a good injection system people are around the area of 25psi on pump gas alone.....all day, every day

        I understand the advantages, but why would you want to substitute cooling for an aditive?

        Joel, your car is going to be down all winter, its not like you wont have time to make something work. you can make your piping...the way you want it, and an ic isnt that expensive. you can buy a good used one one ebay for cheap.

        not only that you dont have to worry about proper applications for your car, you can buy a used side mount and make it work.

            Boost response is my #1 concern, sorry for not putting it in my first post. With the Autoxing I do, and the turbo i decided to go with, I am gonna need every advantage I can to be in boost during autox.

            no race car? becuz homeowner...

              um, I guess you don't understand what it is doing then

              when the liquid is vaporized during injection it pulls heat out of the air........among other things

              Unless that isn't "cooling" the air charge???

              like i said above Auxiliary Injection can "cool" Intake Air Temps, well below ambient air temperature.... whereas even your best and most efficient A2A setup may get close to ambient temp...... never lower obviously

              Back with the rotary and the gt42..... when i removed the IC and just ran AI for about a months time it was amazing the difference in boost responce

                o that explains a lot more, i always thot meth was alternative source for those that didnt want to run race gas/e85.

                    joel if you really want to be smart, just go with huge injectors and E85, then you dont need to worry abou IC or meth, it really is the best option. Along with the larger exhaust volume associated with E85, it can enable you to go up one exhaust housing size with no difference in spool time, or in your case, a little bigger turbo overall. Most guys running E85 notice close to ambient temps when measured in the runner, which will be more than enough power for you.

                          It is an alternative source. :icon_bigsmurf:
