With the help of some documents from [email protected], RSL was able to locate a pre-existing (unused) DME table which triggers the radiator fan based on IAT, I have been testing it for the last few days and it seems to work very well, planning to update my thread soon.Ha, I knew it! You're the man. I actually have the VRSF 7" HD intercooler for both less weight, less blocking of my other coolers and less pressure drop right now but both of your solutions sound excellent. The W2A setup would be nice as mentioned for the drag strip, but I'm also going to be stripping a lot of weight from the car so a well priced IC similar to the VRSF one but half the weight would also be killer so keep us updated for sure!
@ShocknAwe and group, I follow someone on IG who has done a successful N54 swap into an e36 318ti body that is running the S55 A2W system. I'd imagine he has it hardwired and running off of a switch or something but I'll ask him how hes running it just because I'm curious anyway. Like was mentioned above I think the issue was getting it to run with the fan based off of certain driving conditions, I think if one were to wire the pump to full tilt or off itd work fine for racing. Getting it to function like an S55 on a streetcar is the challenge there I'm sure, but I doubt Omar or anyone doing this completely DIY is looking to do it on a DD.
The pump running continuously seems to work fine, though you are wasting energy by running it unnecessarily.
