Currently running an 80/20 setup. 80water/20 meth. What would I do just run some sort of a y-fitting that would split off? Would raising the turn on pressure affect kr at all with my current setup?
Try running a 50/50 mixture of water/methanol. I've found that works great for me.
ok i just installed my 3147 yesterday and everything went good no leaks of fluid or air so we start it and it was cutting off. we was like ok the pcm has to learn so it started to idle fine and run fine my a/f were 14.8-15.2 then my belts start squeling really hard so we checked them and my friend said i need a new belt tensioner went for a test spin and this thing pulls like a bat outta hell on 15psi no problems with the car at all then i take my friend for a test past in it today there was a big backfire when i got on it and the car like turned off and the oil light came on i checked under the car because i thought i blew my motor but there was no leaks and the car was running fine so i drove it home. i think the timing belt jumped timing and the car skipped timing and then the car backfired when the timing belt got back on. my mods are stage 1 injectors, needswings cutout, psi fi sri, stage 0 ecu, check valve on 15psi from the wastegate agp said i shold be ok with 15psi on stage 1 injectors so i ruled that out what do you all think it is?????? sorry for the lack of periods and commas

thats prolly your problem... the water just cools down the iats, the meth is what lowers the knock... try switching to a 80% meth and 20% water, promise that will help it...

I just made a batch and poured it in with the water that was still in the container...so this is probably a 50/50 mix...or will be after it sits long enough. I also reset the comp...with all that I was boosting 17.3psi with a 10.5 a/f and I thought I wasn't going to knock at all but at 5.5k it jumped to 3.5
I will slowly start to increase my meth amount over the next few weeks...One thing though, I made a pull while checking my intake temps. compared to ambient air temps. Intake temps. were at 65 and ambient 55. Throughout my whole pull the ambient remained at 55. That would confirm that w/i is doing it's job correct?
i would hope so, but what keeps knock at bay is running a higher amount of meth than water.... water just cools iats, meth lowers knock. the more meth the less chance of knock
I am having a similar issue, but I'm currently not running any W/I on my car at the moment. I do have a massive leak at the intake manifold... The gasket at the manifold isn't making a good seal. I believe in my situation, the leak is causing the turbo to over work itself (thus causing more heat) in order to maintain the boost level. I'm also set at 17-18psi. I've adjusted the AFR to 10.5 and it doesn't change anything. I only run 93 octane as well. Before this leak started, I could boost 20-21psi without any issues on just 93 octane.
I've noticed that once the PCM sees too much KR, it will automatically adjust timing at low boost to protect the motor. This is why it shows KR at only 1-2psi of boost even when you normally think it shouldn't come close to having KR at those boost levels. The KR count is based on the amount of timing that is removed by the PCM and not necessarily the knock sensor.
You should notice that the KR at 1-2psi of boost will go away after the car is restarted. However, if you go into high boost and cause the PCM to detect an unacceptable level of KR, it will cause the 1-2psi KR issue that you described.

Not entirely true, although this is a discussion for the Water Injection boards.
When the water is converted to steam in the combustion chamber, it absorbs a certain amount of heat (more than the methanol), helping to reduce knock.
Methanol helps by being a higher octane fuel. The best part about the water injection (no methanol included) is that it doesn't affect your a/f ratio at all, so you can run it without a dtec or other fuel control device.

on 15psi no problems with the car at all then i take my friend for a test past in it today there was a big backfire when i got on it and the car like turned off and the oil light came on i checked under the car because i thought i blew my motor but there was no leaks and the car was running fine so i drove it home. i think the timing belt jumped timing and the car skipped timing and then the car backfired when the timing belt got back on. my mods are stage 1 injectors, needswings cutout, psi fi sri, stage 0 ecu, check valve on 15psi from the wastegate agp said i shold be ok with 15psi on stage 1 injectors so i ruled that out what do you all think it is?????? sorry for the lack of periods and commas
