Overheating?

[WASP]

Hi Can anyone please explain how the under tray assists cooling as all the hot air is being forced into a "sealed" area?

It creates a vacuum which sucks air out.

Oil is a great heat soak.

But - you don't want your oil running too cool. Check the proper operating temperatures of your particular flavour of oil, and make sure you are operating comfortably within that range. One of those laser pyrometer devices would be very useful here.

If you need to cool your oil, get a thermostatically operated cooler, and ensure the themostat is set above your minimum oil temp, but below the max. Even if you are only taking 5-10 degrees out of your oil temp, that will be a big help in cooling your engine.

I would not be locating my cooler any further away from the outlet than absolutely necessary. You are putting extra stress on your oil pump, and the more lines and joints etc the greater the potential for leaks. Remember these things consume power too.

I have seen a very neat installation in the cowl on the driver's side, and also in front of the front wheel.

After reading this post an oil cooler is a definite must for my turboed MX5.
Done the coolant reroute, undertray, aftermarket cooler, aftermarket temperature gauge.

Have you done proper ducting? That made all the difference for me and I have the same cooling mods as you otherwise.

Yep ducting was done some time ago........when the undertray was manufactured.

Not having fog lights in front bar.....nowhere to fit oil cooler......not going to cut undertray and not going to fork out extra dosh
for intercooler with oil cooler.....problems....problems.

One way or the other will work it out.

Oil cooler in , oil filter relocation kit in...........runs much cooler.
Next step providing direct airflow to oil cooler.....

What is the coolant re-rout refered to in this topic please?

Thankyou,
Appears to be converting back to a front wheel drive, east-west type layout.
The drop in temperature reading noted from the engine sensor may be due to the change in location of the sensor. Has anybody recorded any water temperature change in the top radiator tank or hose?

Would removing the fog lights help with under bonnet airflow?

[davekmoore]

For a haltech E series, goto the main setup and select ignition map. There is an adjustment called Ignition Trim. To take timing out, enter a number such as -1.0 - this will take 1 degree of timing out across the entire ignition map.

So in "Setup"/"Analogue Inputs" on the "Ignition" tab there's an box for "Ignition trim Range (deg)". This is set at 5 in the "High boot map" settings. I guess I could reduce this and re-save the file with a different name.

But how do I get this info into the car (there's what look like an old type printer cable coming through the dash from the Haltech)?

No offense but if you don't know how to hook up to it I would advise you to leave it alone. You don't have an E series you have an Interceptor as far as I know.

Yupo, yup, and yup.

Dave, a few NB8B owners on the forum use the foglight opening to source air from outside the engine bay as part of their cold air intake setup by using ducting. However, not sure if this will assist with the issue you're experiencing.
