Paul, These are boost hold, after the boost controller has settled things down. Plus std boost controller. I find that the boost control is very quick to...
Ok Ok Ok.... Time to add my piece !!! All the talk about different pressures at each turbo outlet etc. are most likely true, however, the fundamental problem...
A different slant. How can the primary turbo produce boost over 4500rpm, when it is stalled by the cat? (which prevents it from going bang) Secondly, with the...
Hi Mark, not sure if I understand if what you're saying is true. Are you saying that at 4500rpm and over, that the primary turbo stops producing boost? Again,...
Steve, Over 4500 the primary is stalled, no boost is made. Therefore no pressure in the inlet from this turbo. It is now generated by the secondary. I can't...
MY99 B4 RSK (K&N Filter/Forge DV/7 point earthing) Have had it about 18 months now without any problems. After about 6 months the speedo needle just stopped...
Hmmm... as far as I'm aware, the primary keeps boosting til redline. It's small size means that after 4000rpm it can't move a large enough volume of air by...
that would be easily done, pull the lines off of the actuators, hook the IC valve straight up to the vacume resivior, and keep the exhaust valve open to...
Stalled by the cat ?? What do you mean. BTW, went for a drive Friday night, easily got 1 bar on primary between 60km/h and 80km/h in 4th, by 85 it had dropped...
Good slant Mark, but if you hook some boost guages up you will find answers to this. The primary runs ALL THE TIME, and provides boost all the time as well. ...
Matt, it sounds like an electrical problem in general, possibly ECU related ? THe speedo is driven electronically from the ECU, which recieves it's data from...
100% Steve, not sure where Mark is getting his info from. Both turbos run all the way, yes, the primary doesn't produce high boost after 4000 rpm, but due to ...
And remove and plug the secondary BOV if it's an earlier model because it recirculates the pressure of the the secondary until the pressure is equal to the ...
Thanks. I had sort of come to the same conclusion, had a similair problem with a VW Corrado G60. I realise it may not be directly connected but the speedo...
If the Engine Check light flashes when it plays up, you could see what code it's generating. If you have a series 2, 94-late 96, then the info on how to get...
Paul, Had a re-check with gauge Ran the car up the road, 5th gear, WOT from 2k. max boost before the VOD 0.9bar. Pass throught the VOD, and on upto 6.5k, had...
Hi Peeps Got this group listing from scoobynet and from the looks of things it looks like the place for info. Right I have recently bought a 94 Auto GT 2.0...
Let's drop it. I could reply that if we all took what we saw without questioning it then people would still be afraid of sailing over the horizon for fear of...
Thanks Paul. So here's what I found. Codes 12 and 23. Now this seemed odd to me so I decided to reset, on the reset the check engine light was flashing...
David, I've just replace a MAF Sensor to resolve 3 of these faults. These were the code 23,31 and the occasional 66. What I found was that with the MAF doing...
Kylie Thanks for the feedback. I am going to test the resistance of the MAF because I don't really want to shell out for a new MAF if its not broke. If I do...
Mark, I think I know what you're trying to say, and that is that the primary does not produce sustainable boost past 4000 rpm. It does produce boost, but not a...
Geez 6.5k rpm in 5th gear. You must have been going over 240km/h. Where can you get up that kind of speed? And how did you remove the speed limiter? Matt 97...
Matt, you didn't leave the ECU in test mode did you ?? The car will make the hissing clicking sounds when in ECU check mode, everything stops clicking and...
though it was the head gasket... nooooooooooooo it was a blown radiator cap... and a faulty knock sensor... car has been running fine since... woo hoo saved...
Paul, Got my head round the whole thing. Tis always hard getting your point of view/questions over, on a bbs. Much easier down the pub :-) Matt, Mine was...
No probs Mark, it would be nice to have a motorway with the ability to clean out 5th gear like that ! Regards Paul ... Paul, Got my head round the whole thing....
Hi Paul Yeah it was still in reset mode!!! It doesnt make the noise when running normally what a strange set of noises though!!! Well I've managed to stump...
