For what it's worth mine is the same. Anything over 30C and I have to re-adjust my driving habits for take off etc... If it's warmer and/or air-con is on. Forget about it. It's an absolute slug. I actually HATE driving it on warm days because of it. It's not overheating, and EGT"s are the same as on cool days, but its just absolutely gutless. I've just learnt to live with it.

Actually I should add that mine is at it's worst on humid days. So it'll run better on a 30C dry day, rather than a 27C day while very humid. If that made sense.

Yep, agree with Hodge and as mentioned initially, high pressure diesel common rails of any make with inefficient intercooling hate high air temps.
They literally run out of oxygen which is the whole point behind Intercooling. It is simply so you can get more oxygen into the suckers
Drove from Perth to North coast of NSW in November and the difference between night (high teens low 20's) and day (high 30's low 40's) performance across the Nullarbor, S.A. and the NSW outback, which I reckon everyone agrees is pretty flat terrain, was approx 1.5 LPH and 10% engine load.
On the way back I went through a cold front and temp dropped in 1 hour from hours of 42+ from Broken Hill to Port Augusta to mid 20's prior to Ceduna.
You could literally feel the cars performance change and definitely see it on the Scangauge.
Thats also why the guys who improve the delta T by playing with scoops or more efficient intercooling get better performance.
How much better is usually proportional to the $ spent but that is also why you need to make sure you have no leaks or issues in the "standard" induction plumbing or a wacking great driving light mounted on top of the bullbar in front of the scoop.

I am the same Hodge. Cant stand driving it on hot days. I agree with both Hodge & the evil twin, its not overheating but seems to hate having the hot air sucked into it. By the sounds of it an extra bonnet scoop or a bigger intercooler sounds like it may help. I would have thought having a snorkel would help force cooler air into the engine, thus helping this problem.
Snork does pretty much SFA to change charge air temp.Originally Posted by glenno08
The heat comes from compressing the charge air thru the Turbo.
Ergo the more you can decrease the air temp (delta T) whilst maintaining pressure then the more Oxygen gets into the cylinder
Bottom line... loosing inlet air pressure or having a poor delta T means less power and higher EGT's

Would putting a fan under the intercooler to draw air down help at all?

I have an 08 CRD and have towed my camper when its 45deg and have not noticed a large difference in power so it does not sound right to me.
Cannot offer any suggestions on what to look for though as I am a bit mechanically inept.
I have a mate that has a 2009 model that has been having similar problems on hot days, it just happened out of the blue.
Do you have any other symptoms apart from the power loss??
Was a CRD
Thats what I had on mine. A 9 inch puller under the factory I/C. Fits perfect on a CRD
They are only of any benefit at low vehicle speeds under high loads IE flogging thru soft sand etc.
At decent road speed they are ineffective and at freeway speed probably begin to inhibit airflow
When I fitted the new I/C I didn't bother putting it back on as I only do sandy crap a couple of times a year now.

g'day newby, just wondering where you would get IC pressure tested as mine has a bit of black in the top right corner which must be a leak of some sort. now much is it? cheers...G
