Higher boost and E85 or Methanol 9

[Nitr0EngiEx]

I have a mazdaspeed 3 with a built motor and a Garrett 3076 turbo. the engine is 2.4L Direct injection, and holds a fuel rail pressure at 1800 psi kind of like a diesel just not as extreme. I have 9.5:1 compression.

I want to run 400WHP Daily driver but this engine runs on 93 octane pump gas and I am spraying a 7 Gallon per hour nozzle of 50% Methanol and 50% Water into my intercooler piping about 16 inches before my throttle body.

My EGT reads about 1200 F at WOT and i run about 11.6-11.9 AFR. The turbo is flowing about 350 Grams/second of air. at 22PSI at 6k rpm. I am getting some engine knock and am very concerned about tuning the timing higher and not catching damage to the engine. I want to beat on it every day as safely as i can and i have a fully built motor so between the 93 octane gas with spraying methanol it should be enough but I don't feel it is and i do not want to spray more its terribly difficult to introduce the extra mixture of fuel into the intake tract and i cannot program the ECU to read it, it can only compensate.

The MAIN Question: E85 is NOT available around me, 99.9% methanol is available. 106 octane is available but costs way too much for daily driver. Should i just start putting Methonal in my gas tank with the 93 octane because i cant buy E85 ? what other options are there. I want to go up to 26-28 PSI and I want a more solid solution then trying to spray so much alcohol.

And What AFR Would be good for this application

*(please remember I am direct injected and my AFR runs a tad higher then the conventional port/intake manifold injections that have time to atomize pre cylinders and dont require so much fuel pressure, and have more time to spray)

Thanks hemi.
Much appreciated.

APR refers directly to

http://www.goapr.com/

, which is a very well respected tuning company for Volkswagen, Audi, and Porsche.

VAG usually refers to the group of automotive companies which encompass VW.

http://en.wikipedia.org/wiki/Volkswagen_Group

This now includes many manufactures other then just VW.

TSI/FSI, is the type of engine produced for 6th generation (Mk6) GTI's. I believe it refers to Turbocharged Stratified Injection. (See attachement) . I believe VW won several awards with its development as it combines power and fuel economy.

If the OP was driving a GTI instead of a MS3 (Mazdaspeed 3), he could shell out 3-4 grand for a kit by APR for at least 380whp. I realize that the OP might be offended by this, or he might like to "do it yourself".

Sorry for the VAG advert here. hehe

Thanks for the invite to stick around this thread. Will do.

Worrying about what the OP may or may not think is apparently a simple waste of time as he posted this question on 15,May and last cked back on 30,May. Seems like the OP is out of the loop.
