Questions about 2D before purchase

[l2r99gst]

I am thinking about installing a water or water/meth injection system on my DSM. However, I won't install a WI system without a failsafe within in the system. That's why I like the 2D, because I could wire it to shut off my electronic boost controller when a clogged nozzle is detected.

Anyway, in my limited research and listening to experiences from others, I am not sure if the pump in the 2D will suffice for my application, but if I don't use the Aquamist pump, then I won't get the clogged nozzle detection capabilities.

Anyway, here are a few numbers for my car:

Currently, I have only 650cc injectors, which I may upgrade, but for now, they are OK. A little more boost and I will be at 100%IDC. So, if I do a few quick calculations:

650ccx4=2600cc. Let's say a 15% WI. That is .15*2600=390cc. Can the Aquamist pump handle this amount? What if I want to go to 20% or upgrade to larger injectors?

Are there any other possibilities to still use the FIA2 with another pump?

Thanks,
Eric

The aquamist 2d system will br have enough water for your application unless you use an small accumulator - bring the flow up to about 360cc/min at 6 bar. Alternatively use a small priming pump to boost the flow up to ~600cc/min.

The best approach is use a shurflo pump + 2d upgrade kit + a DDS2/DDS3 flow monitor kit.

This way you can have flow + progressive flow + warning capability.

I really don't want a warning system, though. I mean I can wire in any number of LED's, buzzers, etc without a problem. What I need is something that will automatically and quickly shut off my boost controller in the event of a clogged nozzle.

It seems like the FIA2 is the solution, but it will only work with the Aquamist pump.

Thanks for the other suggestions.

The DDS3 can do all those things you mentioned. you can download here:

Richard,

Good news. I found out that there are nitrous controls in my engine management system that I can in turn use to control my WI. I can wire it up to shut off my boost controller at a specific knock level, etc, as well as using the stock FPR solenoid to control boost. This was pointed out to me by another member on this board.

The EMS that I used is called DSMLink. It is a great product, but I was just unfamiliar with certain areas, since I never had the need to use those areas. So, it looks like I will be able to build my 2D system, minus the aquamist pump.

This is great!

At last you are using all the functions offered by your EMS.

I have a question, are you going to map the water or will it turn it On or Off with the nitrous. If this is the case, it is not necessary to use the 2d system.

Please post some details of how the parts are wired up and I am happy to check it over for you.

Richard,

I will not be mapping the water at all. The EMS simply grounds a wire on the FPRS based on user definable settings of RPM, speed, TPS% and knock.

I am going to wire in my electronic boost controller through this line and setup the EMS to deactivate the line above a certain knock threshhold. So that way my boost controller will shut off at whatever knock level I set it at and come back on when the knock falls below that level.

As a safeguard to this, I can also run the pressure lines throught the fprs to the boost controller to achieve the same goal.

I should be fine by myself, but I appreciate the eagerness to help. I just have to test whether this will suit my needs or not. I have to test if running high boost, then shutting off the boost controller, will lower the boost fast enough.

It looked like you have a good plan already in place.

Your knock threshold wil be your safety net. Good idea!

Good luck and post some pictures of the system when done.
