thorpy36 Posted December 24, 2013 Author Share Posted December 24, 2013 Hi guys, I've upped the boost to 1 bar and thanks to my stupidity I found the problem to the holding back. I has the safety limo on the boost controller set lower than the boost I ha set so it kept holding back ...... What an idiot ! So yet that car is loads better for the boost up ! Thanks for all your advice I'm just trying to weigh up where I go next to keep the ca reliable but add some more ponies ?? Any advice more than welcome! Quote Link to post Share on other sites
Addymk2 Posted December 24, 2013 Share Posted December 24, 2013 If that's the case I up my previous estimate to 175bhp what makes the relocated filter? What makes the manifold? Quote Link to post Share on other sites
thorpy36 Posted December 24, 2013 Author Share Posted December 24, 2013 the front mounted filter kit was bought from toy tuning whilst the were still trading but I have put a K&N filter on since then, and the manifold I do not know but it is a stainless standard type tube cut and welded piece. does that help at all.

Addymk2 Posted December 24, 2013 Share Posted December 24, 2013 The K&N will, those scrappy no name £10 filters flow terribly. Lost 9bhp on the misses delsol compared to a K&n! The manifold, if it's an eBay jobbie might not be your best bet when it comes to reliability but will do the job until it dies Quote Link to post Share on other sites
thorpy36 Posted December 24, 2013 Author Share Posted December 24, 2013 luckily I have an ultrasonic thickness tester at work and the tube wall thickness is between 5 and 6mm thick which I was pleasantly surprised at and the welds are all very neat and with near on perfect lay (sorry to be anal but I do a lot of fabrication work) so hopefully it will be ok. if it fails ill get a compact equal length ordered Quote Link to post Share on other sites

Get her dynod lol Quote Link to post Share on other sites
thorpy36 Posted December 24, 2013 Author Share Posted December 24, 2013 My problem has returned !! God sake !! It seems that the car performs really well whilst the engine is relatively cool, but then as it warms up and gets to full running temprature it's seems to perform a lot worse ! You can hear the car boosting as strong and the guage shows it's still boosting at 1bar but is seems to be loads slower !! It's worrying me a bit now guys!!

Addymk2 Posted December 24, 2013 Share Posted December 24, 2013 Any noises that sound different when it's up to temp? Any fluctuations to the AFR? Quote Link to post Share on other sites
thorpy36 Posted December 24, 2013 Author Share Posted December 24, 2013 No nothing abnormal at all, AFR I don't know as I haven't got any way of measuring it without a dyno. My dad seems to think it could be something to do with worn piston rings or valves but I cannot see any tell tale signs of that :/ Quote Link to post Share on other sites
Addymk2 Posted December 25, 2013 Share Posted December 25, 2013 Shouldn't be unless it's smoking, you compression tested it? How much oil does she use? Quote Link to post Share on other sites
thorpy36 Posted December 25, 2013 Author Share Posted December 25, 2013 It doesn't use much oil at all really I haven't seen the oil level move since I got the car. Also no I haven't compression tested it yet but I annoy see a feasible answer apart from it passing the rings ! Could it be an ignition problem, plugs and leads, ie- a weak spark ?

Addymk2 Posted December 25, 2013 Share Posted December 25, 2013 Potentially mate, electrics I mean. When did you last check the plugs and leads? Quote Link to post Share on other sites
paulgtt Posted December 26, 2013 Share Posted December 26, 2013 Lambda sensor is another possibility Quote Link to post Share on other sites
