Hey guys lil prob with My XR6T we have had it on the dyno twice now, the tune is spot on running 15psi with mods listed in my sig, how ever it wont make anymore then 350rwhp, we even put the boost up to 17psi and it made no difference still 350rwhp, when looking under the car after the run, the Cat was glowing Bright orange. where the turbo and the manifold where fine. no mater what we do the car will no get over 350. cat converter?

Thanks

yes

Ive had a few mates with blocked cats and there cars wouldnt rev and ran very doughy, where mine still revs free and drives fine on and off boost? that's whats making me think?

ive seen a cat start flaming because the cat had collapsed inside,, the rest of the exhaust was fine

Anyone else had this happen?

Just take the cat off, look in it and shake it around. You will know pretty quickly.

A tip I have heard mentioned: stick a torch in the exhaust. You will see the shiny flaky bits of the cat core if the cat has disintegrated

Ok thanks guys

just dump the exhaust before the cat and do a run and see what happens..

if it makes anymore power when this happens you know that the exhaust is at fault.

I would also be checking for any boost leaks.

test boost either side of the intercooler and see if there is a boost leak somewhere that could be giving you grief.

Bit of an old thread. Buy did this get solved??
