As the title says, what kind of oil pressure and water temp readings are you getting in normal highway driving?

 

I can't seem to drive it normally on the highway, but ...

Oil pressure ranges from about 25-psi (at idle) to about 95-psi > 5500 rpm.

Water temp ran around 210-230 before the ambient temperature dropped this last weekend.

 

I get 100 psi when I start and drive on a cold engine...which worried me but it is supposedly normal. When the engine warms up it drops down to 60-80 for city driving.

 

23-30 at idle on warm engine....initial start up 90-100 COLD.
Nornal driving 55-65 highway speeds..45-60 city speeds.
Temps run 195-225 normal driving

 

oil pressures look high for today's standard at least. Good info! Does anyone know of a higher capacity radiator that will drop in for these cars? Obviously a cooler thermostat will help, but a more efficient radiator will also help minimize the fans from running so much.

 

Help what?

 

Haha, sorry, I failed to make that point. I was referring to the temperatures, they are normal numbers, but heat is an enemy. In my area where temperatures are in the 100's I would benefit from a higher capacity radiator, just to be able to control temperatures a bit better and lower operating temp by about 5-8 degrees, making for a healthier, slightly stronger, longer lasting engine.

 

Yeah, for sure agree with you regarding heat as the enemy!! However I don't think a cooler thermostat is going to do anything on the warmer days. With the OEM thermostat (what is it 195F maybe?), the car will often run at a higher temp than this. In other words, the thermostat is wide open and the car is still running higher than the thermostat setting. In these scenarios, it isn't gonna matter if you have a lower thermostat..... it's still gonna be wide open.

Frankly, I'm not sure either about the larger radiator. While it theoretically has the opportunity to help, it dosn't mean that it will. In fact, I thought there was a thread in here from one of the fellow track junkies who stated tha the larger radiator really had no effect on run temps. (Maybe I'm just dreaming this stuff up??? LOL) Seriously, cooling is a complex topic and it would be my (limited) experience that air flow management is going to be a bigger factor (and potential weak link) more so than the physical size of the radiator. Some of us just recently installed the Tiger-racing CF 302S hoods - because the hoods are significantly ducted to draw the air out and over the top of the car instead of asking it to go back to the firewall and find it's way under the car. With or without the LS front splitter we've got a nice low-pressure zone under the car, but; 1) the engine bay is cramped enough to inhibit good airflow towards the underside of the car and; 2) given a choice, we'd rather have air flow over the top of the car (aka downforce) and leave the low pressure zone under the car undisturbed!

 

The hood is an interesting topic and I suggest you open a new thread with photos and install tips.
