Engine is running sweet, boost is registering on stock and aftermarket guages, but I'm just not getting the kick in the back I used to, and I notice that my BOVs aren't hissing anymore. I do get a kind of faint rattle when I back off though. Also, the turbo "spool" noise seems to be quieter than it was.

 

Anyone got any ideas? Silly question possibly, but if I had a boost leak, would that mean that less boost would show on the guages?

 

Cheers

Check one of the pipes as i seem to remember that it was starting to crack a little, it hadnt gone through and it may not be that be worth taking the pipe off and checking, think it was the right hand side going to the throttlebody, like i say might not be that but worth a look. If your bovs arnt hissing anymore and you cant hear the turbos then it prob is a boost leak somewhere.

 

Apart from that hows she running?

what boost are you hitting?

have you done a ECU diag yet?

Kirbz - hi mate! she is running fine apart from that. You guys did an ACE job of the suspension - really is a much better drive!! Thanks!!!

 

I just got her back today from getting the clutch done and a few bits and pieces done. It is much better (apart from the power thing). The guy also fitted a smithy hard pipe kit and my rad pipe with water temp sender. He mentioned that he'd replaced the gaskets on the exhaust to turbo mounting - not sure if the problems could be related to that, but I think the BOV problem was there before then.

 

I've got one of those boost leak detectors that you pump up with a bike pump if I can work out how the hell to use it :D.

 

Paul - Not done an ECU check yet, but have a conzult and will do that now. I'm hitting approx 10psi boost on aftermarket guage. When I accelerate hard, it feels normal up to a point, but then when you expect it to really kick in, it doesn't. I think the point where I've tee'd off for the boost guage may be leaking a bit but not much so reckon its more than that.

 

Cheers for responses lads!!

Thanks Vijay!

 

Just checked the error codes after I'd been out for a drive and just go "55 no errors" which is good I guess.

 

I'll try pressurising the system tomorrow and see what that shows up.

 

I'm assuming that if I'm getting usual readings on the boost gauge that it isn't my turbos are cooked or is that a false assumption?

more instructions :)
