What kind of IAT drops do you typically with see with meth?

 

Depends where the meth is injected and how much meth is used as well as meth mixture.

 

I have 2x 10 nozzles and i spray a 80/20 meth/water mixture. I usually see 25-30* drop then it starts to rise back up slightly. This is at 10 psi.

 

My IATs stay about constant with meth, but without they usually rise 5-10deg after 3-5 secs of ~10psi.

The huge drops in IAT happen when people are getting liquid meth right on the IAT sensor, which is not accurate.

 

I am spraying 50/50 with a Snow kit and a #6 nozzle before the SC. The IAT is after the SC. IATs normally are 20-30 degrees above ambient and the meth keeps them roughly the same when I get on it. Sometimes the temp will go up 10-20 degrees initially, but then come back down during the run. When I let off the temp will drop 20 degrees for a short time and then end up back around 20-30 degrees above ambient.

Just recently hooked up my Ultra-gauge so I could watch my IATs, so still figuring it out.

I have my Meth controller set to max spray at 10 psi. Still playing with the max setting trying to determine what works best. If I get it too low it bogs it down at lower throttle settings.

 

Usually you can see around 20 degrees drop in the IATs, but as mentioned above it depends on your setup and the amount you are spraying.

 

I find my IAT follows very closely what my meth bottle is at. It's uninsulated and under the hood in the OEM washer fluid tank, IAT stays warm if the bottle is warm, winter or summer.
