PE down on power

[MikeFish]

Looks like it works on tuned cars too.

Sorry bit off topic now.

All depends on how long I keep the car Mike as have my eye on N/A stuff these days

My bad for not making it clear, definatly and almost 100% the eventuri and especially combined with bigger inlet pipes is a boost maker (if only i had the extra money). But my point was more to the heat soak and lack of power of OP's car.
Not sure if his car is still holding or peaking his boost, if the current ambient temps on 'start up' is ghosting his car aswell or if it is when driving after some time, what are his oil/coolant temps, misfires/plugs lifetime, is the car tuned and or pulling timing (especially in these hot temps that are luckly dropping again).
Heck i once had 1 turbo pressure sensor gone faulty, car lack serious power but no CEL/DIS error but showed up on scan. Can be so many things....
BUT if you say it is seriously lacking power i would maybe first technicly test few things out before flooring it on a dyno :s .

@Mike: sadely small picture but can you share more about your cooling very curious! Looks like additional fans (would be handy in traffic where heat soak enters) + water/meth injection? pm?
EDIT: ah now i see, you got SillyRabbits stage 2 kit . Curious if the charge cooler core upgrade isn't the most ideally upgrade before going air-2-air + meth...

Hi
My understanding is the charge cooler core is still in development for the time being, I’m more than happy with my SRM Intakes, Cooling and Wastegates

Went out in mine yesterday whilst it was chucking it down and a lot cooler. Still feels down on power slightly straight from cold. I noticed what feels like quite a strong misfire on start-up recently. Plugs were changed 11 months ago by Audi. Car isn't tuned. I can well imagine there are a lot of factors at play. I'm going to get it checked over as soon as I can.

What upgrades do folks have for improving cooling? I remember MRC were working on a new charge cooler but haven't seen any updates for quite a while. Does anyone know if they finished finalising the mod?

Quick update - Had the car serviced and then on the dyno today. Coolant leak was spotted but no other issues found with the car. Had the car on the dyno and it did 610 bhp and 778 Ibs ft so not too bad and showed the car isn't down on power (however does have Akra exhaust so would expect better than spec anyway). It certainly felt better on the way home but probably not 100% how it used to be. Car has been lumpy on start-up so may go for NGK plugs if it carries on.

778 Ibs ft so not too bad

778 ft lbs is 1055NM!!!!!!!! I assume you meant 778NM?
If so that is about the same as mine when not overboosting (instead of official figure of 700Nm); mine recorded 773Nm, then 774Nm on first 2 runs then hit 888Nm when overboosting (instead of 750Nm official figure).

Did they log the IAT after charge cooler or logged it is was pulling timing?
Dyno numbers sound good (and i also assume you meant 778NM).
I guess ambient temps been going down bit a bit aswell and that never hurts this engine.
Try to always pump decent gasoline .
Always good to swap plug between 20.000-30.000km imho and...this car needs to be push from time to time once engine is warm to burn off carbon and to keep the ecu learning program 'sporty'.

Were did they spotted a coolant leak? I suppose the O-rings on the turbo's?

Ooops 'Units' failure! Yes I meant 778Nm!

They didn't check IAT etc. The numbers suggest that the engine is ok. The tyres are getting low and it's on the original conti's at 18K miles so they may be playing a part in how the car feels.

The coolant leak is from the water pump housing. It's not a huge problem at the moment (needs to be done) but would have been lowish on coolant when I was feeling the loss of power. It was also when we had the high ambient temps.

Always run Shell vpower without exception. Plugs were done 1 year ago but will be getting them done again within the next year and going to NGK plugs.

It could do with a bit of a sporty driving to be honest as it's been mostly motorway cruising recently. There was a lot of stop / start due to an accident on one journey for probably a good hour. The car wasn't really happy after that so may be in need of some spirited driving!

I'll keep an eye on it and see how it goes...

Well think the answer kinda lays in your reply...these cars suffer big time in low speed-start/stop traffic. First of all the charge cooler pump only runs at 10% when throttle input is very low (cruising). Not that it makes a huge difference but some are running the pump withoit signal wire (or with switch between) to fool the ecu and running it 100%. Not sure if your pump is leaking, if so you might want to upgrade to an cwa100 (stock is cwa50).
Anyway the issue is once the heat is in this block it is very hard to get it out of there.
