Odd Problem - Please Help

[rs200tez]

I have a problem which has now developed since I flooded the rex on Sunday.  To de-flood I removed the intercooler inlet pipe (the bit that connects to the plenum), took out all the spark plugs and turned the engine over with the EGI main fuse removed to remove excess fuel.  I then put the plugs back in and she started up.  Went for a drive, performance was as expected (awesome) suddenly lost all boost and at this point realised that the OEM temp gauge had not budged from rest.  

Found that the intercooler pipe right down by the intercooler had popped off.  I reconnected and she now boosts ok, however performance and the mental sound has gone???  Temp gauge still not budged.  

Car was running fine until I flooded it and now I have these problems - I suspect I may have done something during the de-flood procedure.:2Rolleyes

Car spec is - Single turbo, HKS Fcon Pro ECU.

Has anyone got any ideas please?

does it still hold the same amount of boost as it did before??

i would just have a good look around near the plugs and see if any sensors have come off.

Boost is reading the same (I take a feed from the plenum)... but the insane force of acceleration is not there - nor is the mental sound you get?? All very strange because after I deflooded it - it ran perfectly for 10 mins until the intercooler pipe popped off - from this point it\'s not performing.

Will double check everything I can think of - thanks Karl.

hmm.

well maybe the pipe is still not fully connected properly, have another look around them again.

sorry i carnt be of any more help

It\'s a wierd one.... when the pipe popped off it must have caused a problem somewhere else because it was running A ok.

must be still losing boost somewhere dude ! i take it when you mental sound you mean the wastegate opening ?

Whereabouts are you in Bristol? If you\'re close to me I could come and have a looksy. I might be able to offer some help if you\'re not far away.

Just checked the boost - I get 12psi on Low boost and on max 17psi... exactly the same as before - weird! I\'m in Henbury - on the hallen road in Blaise Dell...  Any help would be fantastic...sometimes a fresh pair of eyes will see the obvious!

i\'m in horfield - not a million  miles away from you.

[rs200tez]

Nice one - save you coming to me - I\'ll pop over to you! You free tomorrow day/night? Do you live just up past Southmead hospital - red FD3?

[nikp]

No,  i\'m not that one. Bit further up. email me, it\'s on my profile, i\'ll discuss there. should be free late afternoon, early evening.

Just to clear this up - A massive thanks to Nik who today resolved my problem. Really good to meet you Nik and congrats on the new arrival.
:cheers
 Nik had a good poke around made sure everything was connected to what it should - then he re-connected the water temp sender (the one by the oil filter). Guess there must be a feed to the HKS Fcon Pro for the water temp from here too which meant that the ECU was not allowing full power. Whatever it was Nik sorted it - big thanks!! I cant believe how kind and helpful people are on here.

On another note - if you are looking for an RX7 - Nik has his for sale which is an awesome example, it\'s got all the kit; recently rebuilt, single turbo conversion, Apex\'i PFC, really nice interior and a cracking bodykit - and in the fastest colour; red

Cool! Nice to know that that sorted things out. Glad I could help you out.
