is anyone using a blow through air flow meter setup on there c20let's?
im running a t3 turbo and used to have the afm close to the standard position but the 3" pipework to it was rubbing on the engine mount and the top rad hose. iv now moved it round to be facing the bumper so it gets more cold air and leaves me more room.
the problem iv now got is that on low revs and idle the car runs really rough with afr's around 10-12. i know the problem is that the afm is too close to the turbo.
iv got plenty of room to mount the afm after the turbo and before the throttle body and this would also eliminate any probs with the car cutting out when the dump valve opens as the air wont have been measured yet.
if anyone has tried or currently runs the setup does it work ok and is there any downsides to it?
cheers
As you say , a known problem due to inlet pulsing, hence why you need to maintain stock intake length. I would expect this problem to be exacerbated by running a hot wire sensor in pressurised, post turbo airflow.
Furthermore, the hotwire is very likely to be quickly contaminated or even broken by oil intake oil vapour. They are about £150 a pop.
none of the breathers are plumbed back into the intake so there shouldnt be much oil vapour in the pipes, just a little from the turbo maybe.
i cant seem to find any info on the search so ill just try it later today and report back
Sorry, are you talking to me?
If so, please clarify and qualify your comment as it appears you are mistaking me for someone else you have stumbled across in your cyberworld. May I suggest you try getting out a bit more?
that was fine apart from the inlet pipe being squashed by everything lol but i never had any probs with cutting out once i changed my dump valve spring, i then changed my inlet and cams along with a few other bits, after that it still drove fine
now all iv changed is the afm location to here
since then iv had problems with cutting out. the pipe onto the throttle body is 3" so i can put the afm onto there and see how it runs. if that doesnt work ill have to try and route the inlet piping with afm like you have. do you have any under bonnet pics?

AFM is 80mm which I dont think is quite 3", just FYI
As for underbonnet pics here's what I have handy. I am just about to swap to a bigger inlet like yours

Not sure if any of that helps you but mine is fine with AFM before turbo as it has enough bends in it to hopefully dissipate any waves or resonance from the turbo. The only thing I had to do is cut the engine mount down a bit to get the pipwork like that and also modify the subframe (not sure if the mount thing will apply in a Corsa - the subframe won't lol)
sorry i completely forgot about this thread, its running fine, 1.5 bar boost and the fuelling is fine and it seems to run well
