![Question](https://www.scoobynet.com/images/icons/icon5.gif)
With todays temp touching ~30°c just how much does this effect performance..?
First summer with a turbo motor, liked the winter performance, just wondered how much difference you normally get in summer heat, although to be honest,when it's this hot (not very often..!) I normally take it easy. For a change

we saw 60°c intake a couple of times today
... causes det and ultimately a fecked engine. car will be down a few bhp cos the ignition will be retarded and you run the risk of expensive damage.

The ECU will alter it's fuel/air mapping and boost control to keep temps manageable. Presuming that the car is running on a decent octane fuel, that the wastegate actuator hasn't been played with and that the car is running a decent ECU programme, there should be no problem running the car in this heat.
These things are tested at much higher temps. I've only seen problems when people, who don't know what they are doing, fart about with the control systems on the engine and remove the safety tollarance.

Had probs with the rally car on Saturday, recently had large front mounted intercooler and dual fan rad fitted, no probs cooling the air but now the damn things turned into a kettle, an only in the forest, get it on the road and no probs, just when it's on and off the power and slowing down and speeding up frequently, it just boils over after aout 3 miles. Removed the front grill and moved number plate to reduce obstruction of airflow but to no avail. Might have to throw the front bumper away!

Might sound silly, but are the fans blowing in the right direction!

My farely standard MY99 UK felt like a dog on Sunday morning, proper slow, then after it'd peed it down in the afternoon, and the air was cool, it felt back to normal. Didnt think it'd be effected quite so much
