High Engine temp

Nick's car got to like 260 degrees today... Probably hotter since the sender was only reading steam.  Is that too hot?

Depends on your meaning of hot.
Hot like Roxy's friend is too hot. 
Hot like lets see what happens when it reaches 260 and find the new holes it creates? Not too hot.

When I am on the highway I have it in 4th and the lockup on around 2500 only. And it doesn't cool down. Is your rad straight up and down? Cause mine is on a bit of an angle and I am wondering if that has something to do with it. Like when the air hits it to hits it and gets forced under my car instead of through the rad.

Sorry, I forgot to answer that question before.
Yes my radiator sits straight up and down and I have the sides blocked from any airflow around but not the bottom.
My radiator is a Griffin aluminum 27x19 single pass 2" from Summit.

So would I be out to lunch by making a bottom fan shroud than? To help aid in pushing all the air through the rad?

I think you should make a bottom fan shroud if your rad is tilted.

Does the car cool down when you're sitting at idle?

Another thing, make sure you have no air in the system.

Ya at idle it drops down to 170 if I sit for say like 5 - 10 minutes.

Do you still have the bottom tray for your car?
If so you might want to put that in as well with your fabbed shroud.

[rex388]

Bottom tray. I think that is a negative.

I have consistently seen a 15-20* F drop in water temperature at highway speeds on the 3 cars I have put lower shrouds on to push air into the radiator.    Definitely worth doing if the car can cool itself down at a stop.

Put that stock lower shroud on. I had the same problem. Hotter at speed and cools right down when sitting with the fan on. I put the shroud on and it's always cool now. I have my fan on a switch temporarily and I don't have to switch it on as much now when moving.
