Hi

LS3 in TVR Griffith up and running.

However oil too hot. Engine is standard apart from MAST ecu and Dry sump system (stage one)

As I sprint and don't live somewhere hot I would like oil to water cooler. It would be easiest to fit in heater circuit. Does any one know the water flow per min in the heater circuit.

Many thanks

What are your oil temps? Mine are running at 220-240*F while running at 2800-3500 rpm. I have a forced air cooler on the engine oil. (fan)

Hi

Running at 80mph about 110c , (176F i think) but used on track 130c (208F) and climbing which i think is too high.
Water temp solid at about 87c
I also need engine to warm up quick for hill climbs etc hence oil to water better

110C is around 230F. If you are running a good synthetic like M1 even 130-140C is not too high: 270-280F.

But...running water to oil "exchanger" is increasingly what the factory is doing to get oil up to 90-100C ASAP and keep over 100C so good idea as you say to get it warm quick.

Steve Heath involved in your project or DIY?

I would LOVE to see pictures. What year? I assume 64-67 as you said Griffith?

Sorry don't know the flow rates. They should be sufficent, can't hurt if you try. I haven't run mine at the track yet or in the Texas summer heat. I may look into doing this. My 2500 truck has a water to oil cooler on it. I argree when my oil temp goes over 250*F (about 122 *C) I begin to worry. Then again the oils job is to take heat out of the engine. I measuring my temp from the pan.

So you are using an infared thermometer and measuring the temp by taking your reading from the outside of the aluminum pan??

I'm not so sure that is accurate, due to the fact that the metal pan will become heatsoaked from the hot oil and engine block. The pan may be hot, but that does not necessarily mean the oil itself is that temperature.

No I have an oil temp gauge and sending unit. The sending unit is mounted through the pan and in the oil.

Thank you all

I will fit oil to water cooler

Griffith is a 1997 car that I have competed in with 5.2 L rover V8 (old buick lump) for 7 years. Quite successful in sprints and hill climbs. LS3 now in and good fun if a little lively in the wet!A lot of Work done by Quick Motorsport
Stock LS3 with Mast ecu, TKO600 box, 12 3/4" flywheel and drysump to get as low as possible.
About 1060kg fueled

Sorry not sure how to load images

Many thanks
