I had a problem with the standard boost hose collapsing, normally at high revs (5K+).
Sussed it out on the rolling road with one of the guys holding it while they ran the car up
Silicone has solved it
Cheers,
Marc.
Incidentally i replaced my cam last year with a Kent CVH35 and i think i prefer my old 90 thousand mile standard jobbie...
Seem to have to ring its neck a lot more nowadays for the same effect, standard cam has much more midrange (Useful)...
