several questions, one thread
 

Havent had a chance to get here recently so the questions ahve been building up, here goes.

1) if im using a water/methanol injection system, would it be safe/possible to switch back and forth bewteen the 2? ALso what woudl be a good rpm/boost point to have it activate?

2)would slightly porting/polishing the tb and removing the secondary plate but leaving the coolant passages intact have any effect?

3)i have a short hose comming off my tb/uim that is blocked off, its directly behind the alternator when looking from the front, what could it be?

4)just to be sure im not forgetting any, can somone give me a short list of the block off plates ill need for a fc with the mods in my sig

5) If im blocking off the omp should i remove the drive gear in the front cover?

thats all i can remember for now, i need a rx7club notepad to carry around for things like this.

1) all the water injections systems that I know of are vac based or throttle postion based rather than RPM based, as far as switching, I suppose if you had two tanks you could switch back and forth.

2) not on a non turbo

3)??? picture???

4) says you have no emissions in your sig... what block off plates did you already use??? at least you would need a ACV block off.

5) if you have it off, otherwise I wouldn't bother.

i would run you water injection about 4 or 5 lbs befor max boost. thats where i was running mine.
i suppose it really depends on what your trying to do

What you can do, which is what some of us do, is run 2 boost settings. One low boost setting that doesnt cause the system to activate, and one high setting, for use with the system. Right now my system comes on at 7 PSI and ramps to max delivery at 15 PSI.

1)I mean throttle postion based not rpm.
I also meant one tank just methanol when i have it and water when i dont. But i guess the same would apply.
2)The tb im talking about is goign on my 6-port turbo,

4)AS for the block off plates, the car came with these installed and im buying ones for the turbo manifolds.

5)The front cover isnt installed yet so taking the gear out wouldnt cause any problems right?

Also someone told me that removing the front cover while installed(rather than vertically) can cause something to slip off/free and cause problems later. Is there any truth to this?
