Neither :wink:
Knock would be my main consideration

EGTs are affected precious little by W.I. (strange but true!)
IATs are affected only a tiny bit - depends mainly on the location of the nozzle, post-ic temps and methanol content

Emergence of knock's ugly head is what WI is meant to fight best.
On the subject of knock, i been having a few issues with my boost control solenoid virtully since i took the intercooler off and the car has only been running 12-15 psi when it should run 18psi, i havent worried about it until the new 3-port boost solenoid arrives(which is sometime away) and a re-tune . But today i put on my old manual bleed valve in a set the boost to 17psi and the once the revs got around 4500 WOT full Boost the knocklink would light up like a christmas tree but i backed out of it before i got the red light up, this is scary stuff :shock: :shock: so either my WI isn't working or bad fuel or i just can't run anywhere near the same tune as before with the intercooler??

Do you have any means of monitoring water flow? an inline pressure gauge may work quite well.

Ok car was just run at the Strip and............. it run pretty ordinary well it was launching really good and the 60fts were in the low 1.8's and leaving rival cars doing catch up but half track onwards it wasn't producing the power and other cars( mainly 1's running low 12's) would pull about 4-5 lengths on me by the end and the best it run was 13.3 @ 98 mph i got better running a smaller turbo and the intercooler... So my experment is over :cry: the intercooler will be going back on and upgraded later but i won't touch the WI the knock resistance is incredible running port injection..

This was I good test and usefull info! WI been known to do it's best by det. supression not by intercooling. So, some intercooling takes place, but it is limited to ambient condition and set up specs.
