Cat Blow Out

[Alion]

Well where to start, I guess on tuesday the 8/7/08, the car was taken in to be tuned up gain as it seemed to have lost all of it power. As a dinorun showed at a car show a month before, only making 287HP at the wheels (yes horse power). When the car was brought it was ment to be making about 340KW at the fly. So what went wrong?

Well thax to a good mate (the guy who is tuning the car) and a fellow XR6T owner he can be trusted. So back to tuesday 8/7/08, car was on the dino for a full day of tuning but strangely enough only making 8psi of boost, when they where tuning it for 15 after much pondering on what the problem was they found a somthing a little sus. a bolt off the manifold to the turbo was gone and the rest was lose! so they pulled it all off looked at it all and found that the manifold was now bent. Was then michained and the such like. was the end of the day so car was layed to rest to tomorrow.

Wednesday 9/7/08, car was to go back on the dino later that day after the car was put back together and everything checked they found the bolts holding the turbine housings together where losse! So apart came the turbo. Was inspected and checked with no damage was put back together and it was the end of the day.

Thursday 10/7/08 the baby was put back to 1 again and went on the dino later that day with it still only making 8psi they decided to change the actuater. They had already tested it to make sure it wasnt the problem but better to be safe then sorry they thought. But still no luck 8 psi max boost. Then again what do you know it was the end of the day.

Friday 11/7/08 (today) they found the problem!!!!!!! they decided to check the intake and exhaust system (as the compression had been tested about 1 month ago and came up fine). Well the intake was good but the Cat had been blowen out into the system and was doing a great job at chokeing everything up. So there was so much back presure the max boost was 8psi. So now that I have a cat case with no cat it will be staying that way till I have the money to get a deicent one.

Just thought I would share my problem with the world and at least the problem is fixed now. I dont think I am going to get sloged for all the time that has gone into this. But I am still going to have to pay for the machineing a few other things. In total I think I came away with a bargen and the service is fantastice but these guys are know for it. They are nispro accreated and they will be getting a letter of apreaction. (but I think I might use spell checked for that)

I was really struggling. At least there were a few full stops here and there to break it up.

Well doesnt look like I can edit the first post so here it is all again!

So now that I have a cat case with no cat it will be staying that way till I have the money to get a decent one.

Just thought I would share my problem with the world and at least the problem is fixed now. I don’t think I am going to get slogged for all the time that has gone into this. But I am still going to have to pay for the machining a few other things. In total I think I came away with a barge and the service is fantastic but these guys are known for it. They are Nispro accreted and they will be getting a letter of thanks.

Sorry if it was hard to read before I am a terrible speller and I got a lovely case of the flu.

lad to hear it all worked out in the end. It can be very frustrating trying to locate a problem such as this. Kudos to the workshop for looking after you.
