Lost some boost

[Purple_rob]

Hi all,

just wanted to trouble shoot this one before i go looking for the problem.

The car is completely standard and has been running about 3/4 boost on the dash gauge. In the last couple of weeks it's dropped to about half way in the gauge and I can feel a small difference in power.

Cars still running beautiful and can't hear any leaks when accelerating. Anything specific I should be looking for?

Cheers

I'd start by taking all the boost hoses/pipes off and checking for splits. Make sure all the jubilee clips are fastened tight when you re-fit then :)

also if you got a dump valve check that out :)

and your inter cooler :)

Carb top O ring, If you have the anti perc fan still in situ check that the valve on the anti perc system is operating correctly.
