i guess this is a good place to post this......
ok, so im off to the dyno on dec 7th. got 2 hrs to mess around. with the weather change i wanted to get a good handle on my afrs. dont wanna risk get pulled over doing 130.... ![]() im going to, Luckys they have a in-house, load based, DynoJet 224xLC the guy said they about 10% above a mustang but lower than a normal dynojet. so i dont care about numbers. ill post them but i dont want to hear any blah blah blah about it... im goin to see if i can improve from where i am now and what works best... this is open to discussion, lets not be stupid.. 1.) since i trapped 119 with 22 psi this is where ill start. ill get my afr on point at 22 psi. ill test on water and off water...... 2.) then ill do 26 psi, just to see how much power it brings me up to, check afrs, for kn water on and off... 3.) ill turn the boost up to 28 psi, get the afr straight check timing look for knock, then do a final run on water then off water. 4.) if i got some time left ill try to squeeze alil more timing out of it. ill use the water as the cusion.... but ill only run it at the track. if MBT isnt already achieved... ill play with it... as of now i start water spray at 20 psi on a DO4 nozzle. i can start earlier if needed if yall think it would be better what you guys think?

In for results...
My guess... since you have your IAT sensor zip tied to the front of your car you will not see any benefit from the water cooling the intake temps. But you would see a higher knock boundary because of lower EGTs. I'm interested to see the results. I want to run meth/water to lower my IATs. My car is an animal on cool days. If water would make it behave like that year round it would definitely be worth it. Although your study isn't going to answer that question, I'm curious how water will effect your numbers.

The water is still going to cool the Intake Air Charge. Sensor or no sensor, its still cooling. If the PCM sees it, it will add timing, if it doesnt then it will not change the timing, but its still being cooled.
Your on a boost box right? I can't run 29psi with my software on 3 bar sensors. I seem to remember the software telling me that's the overboost barrier or something.

Now finish typing.

Quoting myself lol I'm doing it tonight. Ill let ya know cano. Well I don't get wrapped around numbers I just want see MBT and if water is helping or hurting. Also if I can improve my numbers and see if I can hot lap(back to back pulls) with out losing hp on water and e85. Ya know. On meth and water I was able to dyno 3 times in a roll and only lose .2 hp.
