Dewitts radiator
You guys running twin turbo with a Dewitts radiator ONLY. What temperature drop can I expect. Today it was 90 degrees and 80% humidity and I was running between 212 and 220. A little too hot for me like to get down around 205 on a cruise.

Probably not all that much just switching rads. You'll most likely see more results from larger fans and increased ducting to route the air towards the radiator.

Oil temps run between 210 and 220. Got a 160 thermostat in the car. Fans come on at 180 if I recall. Got a response a while back that you can program fans to stay on until 50mph. They now come on and off at 35. Have not done this change yet
thanks,
thanks,

Sorry for intruding, but I'm kind of in the same boat (boosted with stock cooler). When this topic is discussed I see much info about fans and when they kick in etc. What I wonder is how big improvement you get from a Dewitts when you are tracking or "streetracing"? In other words, in speeds where the fans are not operating anyhow? In Norway 90 deg is the highest we ever see, and the stock cooling have no problem keeping the car below 210 deg in stock and go trafic for an hour. And frankly, as long as you don't go near the red zone, what temp you get in trafic doesn't really matter? It's when you really are "on it" that matters, and then you are up in speeds where fans doesn't operate (or have an impact) anyway....?
Last weekend I had one 20 minute test-pass on a track in approx 80 deg. Water temp stayed around 210-215 deg, and oil temp at around 250 deg. I don't think that is bad at all....
