This is the final piece (I hope) to the puzzle that is the high IAT's (Intake Temperature) only at the track when on WOT (Wide Open Throttle) for prolonged periods.
After upgrading the existing cooling capabilities of my Chargecooler by adding a bigger water reservoir I came to the conclusion that a Water Injection system was needed for extended track sessions.
Don't get me wrong, just the Chargecooler is more than adequate for street use and mild track sessions..but I want to be able to do longer sessions and also lengthen the safety margin of the engine because atomized water in the engine is a great knock limiter.
Ok, let's get started.I opted for a Snow Performance WI Stage 2 kit with MAF/Boost switch.I will use the Boost function since it is preferred for centrifugal applications such is the Rotrex. I was determined to use the existing windshield washer reservoir as it is in the lowest position possible in front of the passenger's side wheel liner and is rather large (holds almost 5 litres).
You can see it in the picture below:
To remove it you'll need to remove the front bumper and passenger's side headlight.Then you'll need to drill a hole so that the quick release plug can be installed, don't forget to add the goop sealant.You can see in the pictures below the completed reservoir:
The WI pump needs to be close and under the reservoir, so you need a make a mount for it to sit directly under.It is quite easy because you have a lot of mounting options at that position.
Check the pictures, so you can get a general idea..remember that it is wise when adding weight try to position it at the lowest point of the car:
Moving on, i wanted to achieve a stock-ish look and avoid many visible cables so i installed the WI controller inside the glove box.
I drilled three holes for the three wires to pass through:
1) Black wire is ground
2) Green wire connects to the pump
3) Red wire needs 12V power source.
You can cut the Yellow wire since it is used for MAF applications and i will use Boost controlled operation.
Here you can see some pictures of the progression:
A big thumbs up to my buddy Sikrip for helping me out with the wiring, schematics, positioning...pretty much everything.. :p
To be continued..tomorrow because i have a party to attend to! :)
