Potential Boost Leak

[adamm306]

Hi all as some of you are aware I crashed my P1 and recently bought a P2

it has a cat and a lucas which could be the reason for it feeling ALOT slower than the P1 but my guess is a potential boost leak

when driving the turbo is very loud and i mean when im driving at 60+ it sounds like the heater fans are on full blast when I put my foot down and it seems to struggle to get up hills.

Other than the big pipe on the left hand side of the IC and the D-seal where else can I check for leaks if anywhere?

before anyone has a go at me i have searched for this only guide I could find was a paid subscribers one on 306.net

Any help would be appreciated thanks.

Sounds like a boost leak to me!
I'd be looking in the places you say as well as the manifold gaskets
You'll ideally need a boost guage to check what psi you are actually getting

If you ever need a hand with anything. Me and tom are quite handy with a spanner and I'm like 2 miles from you lol

ive had a boost gauage for like 2 months but never got round to fitting it lol

and yeah thats awesome are you on facebook atall? its easier to get in contact with people on there could do with a hand now and then

ill order a dseal anyway as if im inspecting it might aswell change it


thanks

Are you getting allot of on boost smoke? If not more fuel and boost!

bump.. where else can i check except these 2 places

the pipe coming off the bottom of the IC in the middle (where you connect a boost pipe to) seems to be bit oily after a drive hard could it be leaking out of here?

Yes could be that.

Split pipe from turbo to intercooler, could be either of those connections.
Could be a split intercooler (rare)
D seal could be f*cked.
Manifold gasket could be leaking.
