Hi can someone tell me what would happen at WOT of u were experiencing heat soak. As in my previous thread i have fitted a apexi cone filter with a samco u bend (thanks pastures) but i need to fit a heat shield and cold air feed. But tonight a couple of times when i opened it up mainly in sixth it seemed to misfire and stutter. I looked at the boost gauge while it done this. It went from 15psi stuttered down to about 13psi then it stuttered up to about 15 psi then onto 18psi at which point i eased off. Could heat soak cause this or do u think something else? Thanks for your help

sounds much more like an air leak to me..... Usually have more probs with heat soak if its been sitting for a while, just feels sluggish for a few seconds until you start to get positive airflow (cooler air) running into the engine bay. In sixth I'd say you already had that

Air leak or coilpack/HT problem more likely... Heatsoak as David says feels more like general sluggishness as the ignition is less advanced with very hot intake air temps.Paul Nugent

I take it from air leak u mean boost leak? If i was to have a boost leak how would the boost gauge react? Thanks again3'' Longlife Exhaust, Koni Adjustables, H&R Springs, Full RS2 Setup with Mr Nugents RS2 Chips (just need the RS2 Airbox)Comment

An air leak can mean un-metered air (by the MAF) getting into the system after the MAF and before the turbo.formally RS2 +Comment

This problem has returned or probably never gone away. I have had a health check by MRC and they also looked at the coils which were fine. That showed up no leaks of any kind. Today though after trying to get to Bluewater ans sitting in the traffic for an hour or so the car did feel sluggish and when i gave it WOT it spluttered then it will pick then splutter etc. That sounds to me as though it heats soak according to s2driveruk post. What do u think? Will this be damaging my engine this hot air? Thanks3'' Longlife Exhaust, Koni Adjustables, H&R Springs, Full RS2 Setup with Mr Nugents RS2 Chips (just need the RS2 Airbox)Comment

Its still happening, but it does not happen all the time. Im going to put my airbox back on. It seems to happen more now the weather has got a bit warmer on long trips and after traffic. Could high intake temps cause a small jolt or hesiatation? It does not seem to pull like it used to. What do u think?3'' Longlife Exhaust, Koni Adjustables, H&R Springs, Full RS2 Setup with Mr Nugents RS2 Chips (just need the RS2 Airbox)Comment

definately.....once hot and stationary you will get a quick buildup of heat under the bonnet. I doubt it will cause any probs with the engine, just as the intake air heats up IIRC there is a sensor on the inlet manifold which retards ignition to protect it. Getting as cool a charge as possible is the best way to gain performance (just like running it on a cool misty morning). If you are running a cone or similar then you need to separate it from the heat of the exhaust manifold and ensure its fed cool air from the front of the car (maybe via some ducting). I'm about to use a brake duct with two cold feed pipes to the K&N i run in an attempt to give it more cool air.
You could also search for bacofoil as this was a good, cheap mod

Check out the Mods on Charlies's MTM RS2 set up for a good sheilding solution here: http://www.s2forum.com/forum/showthr...hlight=RS2+MTM
Personally I don't think a cone filter is really worth the effort for the potential small gains (5 - 10 BHP) vs loss of hot weather performance, lower filtration and lack of OEM look!
That's just my 2p's worth...
