So look at what lag may be introduced. We are basically comparing these two options. http://www.fr33z3.net/starions/tubes.jpg Let's do some rough numbers. The additional distance with the additional bends is about 750mm. To keep the numbers nice and round, a 2L four stroke engine at 3000rpm pumps a ...

One pragmatic way to look at this- Since the boost sensor/ waste gate actuator is down stream of the bends, as long as you are getting the boost you require, the bends don't matter.

When you disconnected the MAP sensor did you plug the vacuum/ pressure tube? Iff not it will be bleeding boost.

bends don't drop pressure temp does ..........the only thing that will change the pressure of a gas in a fixed container is change the size of its container, or change the temp of the gas nothing else. The thing is that air in an engine inlet is not in a fixed container. It is flowing. Flow is caus...

Thanks for the tip Merlin.
I checked the coupling and it looks OK, but as you say very hard to see!

Thanks for the reply Spidersweb.
Sounds like fine tune and put up with it is the only plan.

Hi everyone! Way back in 1994 when I sold my :( HR Premier '86S 4 speed... ( :? before your time?) and bought my Starion, I was amazed by the Starion's quiet sophistocation, however these days in comparison to the new Commodores and Falcons I drive at work, I find the lack of precision of the Stario...

Well, I just got back from my test drive. Some migh think five hours excessive, but that's my story and I'm sticking to it! :pimp I did have to make sure! The good news is that the replacement of the split boost sensor / MAP hose (perhaps combined with the waste gate now working) seems to have cured...

Thanks to Alpos for the reassurance. I have now freed up the wastegate! It is a bit like cutting cheese - there is some friction there but it is now easily movable with one finger. I didn't have to take anyting apart. When I put a spanner on the nut on the end of the shaft it was so tight that the s...

Well, I hope to get out and have a long drive over the weekend to check on the status of my list of symptoms. Hopefully some or all will have been fixed by the replacement of the split vacuum hose; and big thanks will be owed to my on-line helpers. :beer In the mean time, the stuck waste gate has my...

Thanks to flav and Spidersweb for helping me get into the lingo! these abreiviations are a bit of a problem for a newbie!

:oops: So is this the "MAP"? http://www.fr33z3.net/starions/starion0001map.jpg As near as I can tell this is what the manual refers to as the "boost sensor". Does "MAP" stand for anything? The power steering pump in my car is at the front of the engine bay and not near ...

Hi Flav! Thanks for the suggestion. The disy cap looks prestine inside, but the rotor looks a bit ratty so I might replace it. Sorry for my ignorance but can you translate the "where and what" of "MAP"? I found "MAS" and "SAS" in the manual but "MAP"...

Well, after buying a new multi meter I discover the throttle sensor and variable resistor are meeting specs so I am off to check on the waste gate. While playing with the throttle sensor I found a split vacuum hose so I did a temporary fix on that an will buy a new hose tomorrow. Fingers crossed. Th...

Hi again, Thanks for the help Merlin, Big Boy and Entaran. I have checked the throttle sensor against the manual and it is out of specs at 3 k ohm instead of 4-6 so that is a start. Have to grow a few extra hands to complete the test :-) Holding the multi meter on hte pins while moveing the throttle...
