Just to let you know on yesterdays evening WOT run the ambient temp was 69 degrees and the air intake temp was 107 degrees right after the run.

Also, notice my washer fluid level after 200 hundred miles (about 150 highway and 50 city/WOT). I think that the washer fluid bottle is enough if you are planning on using the 100 ml nozzle.

Here is a picture of my current setting. Basically it initiates at 3 and goes full power right after that due to a small (100 ml) nozzle.

Can't do Adam. My air intake temp sensor sits just before my secondary nozzle (currently not in use). Therefore, if I hook it, it will not register the intake temp.

Ugly air box base (waffle pattern) eliminator. For those of you that would like to eliminate the dirt catch waffle pattern air box base. Not shown is aluminum heat shield material that I contact cemented to the back of the shield to keep some of the radiator heat away from the air filter/intake. Ram air flows directly in front of the air filter when at speed. Enjoy

I'm planning on transplanting the thermistor from the MAF into the MSD IAT, but I believe BHR may have a better solution in the works.

Regarding IAT, I just pulled the IAT in the UIM and tested the resistance against the stock one with both sitting at room temp. They may have been okay for the Int-X, but its not compatible with the stock PCM and your IAT readings as read from OBD2 will be off. It looks like the one Pettit's used is a generic MSD IAT, but it unfortunately doesn't have a NTC thermistor temp curve that is identical to stock. In my experience, it looks like its about 10-15 degF off ambient at startup, it could be more or less as the temp goes up from there. The characteristic curves of thermistors are not at all linear.

Here you go:
Ambient temp 76 degrees and IAT 115 degrees after WOT from 1st to 4th gear meth on.
Cruised for a couple of minutes to bring all temps back to stabilize temperatures.
Ambient temp 76 degrees and IAT 127 degrees after WOT from 1st to 4th gear meth off.
See pixs.

WIth just a 100 nozzle! Pre blower! Great work Juan---you da man.
Your intake fab looks smooth too--really good job. i did something similar but mine is with a different material. heat shielding aluminum stuff. then I have the Mazsport coils on top of that. Turned out nice.
Our ww tank---is it a 2 quart? If that is all you have used then maybe i dont need the 7 quart ? Typically its about 30 miles of haul ***.
The more i read and learn about the water meth the more I like it for our car. Rich a/f seems to be a little overrated?
I have torn down my other engine and I sure have learned a lot. Not good i am afraid. But i dont want to take away from what you are doing here---keep going man--really--really good.
I little hint--take washer off the leading plug and go barless.

What's really neat is that if you are using water injection strictly for detonation-avoidance, then you need no alky to do the job and you need no huge nozzles, either. On the other hand, using a slightly richer A/F than MBT will remove the need for having to re-fill a washer jug all the time. The reason alcohol started to be used was to try and restore a bit of the power lost by using water rather than the proper fuel for a given situation.
