WRX-STI Stage 2
Part Number [5101]
Designed to Utilize a factory 2 bar MAP sensor

This product page is for"WRX-STI Stage 2" which are manifactured by DevilsOwn Injection and are in the catagory Subaru.

Devilsown Alcohol Injection kit customized for Subaru WRX/STI utilizing the stock 0-5 volt output MAF sensor. The Digital Variable Control unit proportionally injects more or less water-methanol according to input signals from the mass air flow sensor. This is for the person who wants to have full control of there Alcohol/water injection needs.

DevilsOwn Progressive water alcohol injection kits main function is to suppress detonation caused by high temperature and pressure developed within the combustion chamber when the effective compression ratio has been taken beyond the auto-ignition point by a turbo. Compressed air is heated air which causes power robbing and engine destroying detonation. On a stage 2 car expect up to 18 psi. Stage 3 or 4 cars have been known to run as high as 24 psi on 93 octane with our alcohol injection kit .

Cool the air with the DevilsOwn alcohol water injection kit! Water, with its high latent heat content, is extremely effective for controlling not only the onset of detonation but also the production of oxides of nitrogen in the modern lean burn engines. Methanol with its 116 octane and high flash point and specific gravity further reduce the chances of detonation.

Progressive Controller dvl-2002

The electronic progressive controller represents the latest technology in Water/Methanol system control. The dvl-2002 is designed to increase injection pressure over a user adjustable range and quickly shut off when boost pressure drops to prevent misfire.
