This is the 1st time anyone has posted IAT values and honestly they seem a little high. This is totally performance related. You stated around 158F max iat on the dyno and then changed some stuff and said at cruise you were around 70-100F above ambient. If I am reading this correctly there was something wrong with the intercooler setup. I see those temps if I have my heat exchanger out of the loop after full heat soak. That is why I ask how hot it was outside and what were peak iat on the pulls on the road? Was it around 70-80 outside? Did it get over 200F iat?
The heads have been pulled. To the naked eye, they look okay. There's a fair amount of black residue on one which we are hoping is of no consequence and can simply be cleaned up. Both have been sent to an engineering shop for inspection. The battle damage report is yet to be finalised (he remarks nervously).

1990 300ce supercharged and intercooled
So the reason I ask is that besides being able to make more boost the entire point of a larger supercharger is to make more boost at lower outlet temperatures. So given that I think that something was not working right.

As part of the bleeding process, my installer ran water into the s/c water inlet port until it exited the out port without any air bubbles. Now there's a good volume of oil in the s/c that got sucked in when the engine failed. The unit is going to be shipped to Weistec so they can clean it out and pressure test it etc. To their credit, they have agreed to meet me in relation to the costs associated with this exercise.

We made some mistakes with the cooling.
Initially we plumbed the system as follows: trunk tank - h/e - I/cooler - Bosch pump. On Weistec's recommendation the system was re-plumbed to accord with their installation instructions.
Secondly, the piping beneath the chassis was initially 12 mm inside diameter piping. On Weistec's advice, we replaced this with wider piping (I think 16mm inside diameter and 19mm outer diameter).
The IAT sensor was checked as part of an elimination process. It was functioning correctly.
Weistec did ask us to install the bigger upper pulley which I had bought with their kit as an extra.
We didn't do this. Our reasoning was that once the plumbing issues were addressed, it became clear that the IAT problem was less boost related than it was non-boost related. As set out in the OP, under boost, the increment in IATs was slightly lower on the Weistec unit than on the stock s/c - presumably as a result of the bigger, more efficient intercooler. That being so, our focus was on determining why at idle and with casual driving, the IATs would climb so quickly to uncomfortable levels.
We were also asked to re-run the car on the dyno but with ice in the trunk tank. We did not do so. We should have.

INMYOP def added to fluf dyno #'s to sell more kits, why else would they add it to their test car to make 570 rwp or tell you to re-run it on dyno w/ICE to achieve advertised #'s
So what would Weistec's rwhp be w/OUT ICE? 570 rwp minus 30-40 rwp = 530-540 rwp hmmm

I'm not Weistec but I think I've concluded from their other posts that the reason they wanted ice in the tank was to see if it melted after a pull or two. This would indicate that the fluid was indeed pulling heat from the blowers discharge like its supposed to. A few pulls with no change in the temp levels of the tank might indicate air trapped in the system or fluid moving either too fast or too slow to transfer heat efficiently.
I don't understand Weistec's rationale here using the trunk tank full of ice? It ONLY gives temporary hp/tq increase making the car read far far below ambient temps UNTIL the ice is gone about 5 min later (from my own exp you can see as much as 35-40 rwhp on V12 TT's) IE Wesistecs 570+ rwhp results w/Trunk tank of ice are most likey TRUE but after the ice is gone so is the 30+ odd rwhp gain (I don't know exact amount of hp/tq gained on 55k platform but I do know it's substantial, OBVIOUSLY worth the massive headache for Weistec to fab/install ice-tank)

Their reasoning had nothing to do with increasing HP(albeit would do that), it was to verify the efficacy of the intercooler. They hoped that if the ice didn't melt away quickly then that would show that there might be air in the system somewhere stopping the flow. Of course if the opposite happened then we would know the system was flowing water just fine.
But it's still raises hp/tq nicely albeit temporarily...

Still I'd love to see this Q answered

I was curious on this too so I went and stalked their announcement thread

None of the runs were with ice and all runs were done on 91 octane fuel. We recommend running 17psi on pump gas. Thank you!

If they topped out @ 570 rwp w/out then 600 odd rwp easily in grasp
Sorry I'm not buying they didn't run ice on dynos for 1 second.. Thnx for checking old info though
