Thinking of going e-fan

[driftxsequence]

Where do you read your temps from?

The one time I tracked my car with my v-mount I guess it wasnt sealed well enough and after 3-4 laps the temps would get to around 200, and then slowly climb. I stopped around 210 out of fear and coasted for a lap. they would come back down and go right back up. Is this safe or too hot when on the track? Does a second oil cooler help lower this as well?

Also...what do you guys have as a fan shroud? I have a basic spal fan with a sheet of stainless steel sandwiched between the radiator and fan. When the fan is on it works great, but on the highway it'll creep up till i turn the fan on and it goes back down. I've read about relief flaps but dont know what to use.

S4 T2, Vmount, megasquirt, bnr stage 3, koyo rad, etc

MoTeC with a CAN to the AIM dash, so I read it where the ECU sees it, right behind the Tstat at the hottest point.

It's fine, there's nothing wrong with that.... most modern cars run at that temp anyway

Depends, what are your oil temps?

Custom built AL

SS retains heat more than the AL will shed it... you're basically retaining the heat with that piece of SS. Also.... the fan needs to be spaced off the radiator at least an inch. This will pull more air through a larger area

Mistake number 1 is have a switch for a fan... it should be automated

I'm making a lot more HP and don't have cooling issues..... my temps on a 104* track day never saw above 185* coolant 200ish Oil. How well ducted is your VMIC setup?
