What happens if it breaks up in there? Exhaust housing maybe or in the DP and account for the temp difference somehow?

Yeah dave get a new turbo ill ale use of your old one lol
Don't like the idea of tapping holes in cast pieces.
This garrett flange landed today (Volvo end cap for scale).

I have a mind to have a short divorced pipe run from the top for the Wastegate. Bearing in mind that the flap doesn't open fully (max angle - 30 to 45 degrees?) so the gas will still bounce around. The wastegate is still divorced in the housing anyway
http://i1279.photobucket.com/albums/...psna0bqr9f.jpg
I don't want to change the garrett housing because it will mean completely reworking the DP.
Rate things are going currently it will be winter again before this car is even back together.
No I will go back to Chris Tullett, where the DP was made if anywhere. It is likely that additional tubing will need to be added to the existing 3 inch pipe because the low profile v-band adaptor was taller although it is possible to weld another 3 inch v-band flange on the new flange - but the design begins to get too complicated.
The only other way would be to remove the middle piece in this flange, create a bellmouth collector based around the whole thing and collect it into a V-band. Not particularly keen on this, as this is essentially what the original cast low profile thing does - albeit a bit more tightly packaged.
No I think a short divorced pipe is as good as a divided bell-mouth.
At the end of the day I am trying to design something that is relatively cheap to achieve for the minimum amount of changes and maximum free flow. The gas in the main channel even now hits no change of direction till it is into the dp.
My other thoughts include using this new flange to create an angle v-band , to reduce the turn on the dp itself. But this is again means throwing away the current DP.
Nah - I am getting a divorce(d).
Yes you can't beat a good bit of flange.
Well only a small update to say that I got sometime on the SSB on Saturday. I think I have broken the back of the main re-assembly. Turbo and exhaust manifold are back on. At the moment despite the new flange thing - I am just running to get it running again, if you know what I mean. I am not sure there is room to pass the brake servo??!
I need to order a new cam end cap (where you non-ME7 peeps have that ancient thing called a distributor cap)
and 1 or 2 ancillaries. Just the DP to reattach, put the coilpacks in, air feed, water and oil.
If it doesn't go bang after the May dyno run - then perhaps I may look at re-designing some of the DP/collector section, but I would like to get my coilovers on and finish the new pipe work (I bought the DO88 in the end)- but it needs a TIAL flange welding on to it.
Did a lot today. Replaced the 2 water hose connectors for the oil cooler. Aux belt back on and pretty much everything else. Mocked up the top pipe from the DO88 RIP kit - and marked the position for the tial flange. Unfortunately the one in the kit is aluminium so I will have to wait for a S/S one to land.
Hamish was his usual supportive self LOL. First restarts are always a bit terrifying...

Found out what the problem was - namely there was no fuel left in the tank. Soon rectified and she caught on the 3 or 4th turn. Bit more fettling/re-assurance (checking for leaks etc) but a very satisfying.
Great news mate.
Nice one :)
She's alive....will be ready for RR day..?
Awesome news dave
Great news, well done Dave.
Result, hopefully you'll get some good times and bhp figures
well done, will be nice to see what she can do now
Without making any other changes I am expecting a small improvement because the exhaust cam timing may well have been slightly out.
Next comes the suspension change - perhaps Saturday if I can get the time - surprisingly without the need to remove my driveshafts. Check for leaks and give her a long awaited wash.
After that I am looking to consolidate and get some decent data logging.
Without the need to remove the driveshafts..? But James said.... oh wait. :cuckoo:
Funnily I changed, shock legs, wishbones, drop links, krust and underseal the wheel arches without the need to fiddle with the brakes or remove driveshafts.
I bought my Silver C70 T5 9 years ago in April/May 2006 - so I am not new to this game - like anyone would need telling that. For 6 years (basically from box to bin) I ran a TD04-19T on that car with varied success. Since the end of 2012 I've been pushing the envelope with this GTX garrett conversion project.
Lets face it - I haven't been very successful with it to date. Span a shell on the 1st engine within 6 months in 2013 and last year the Garrett managed separated the block from the head.
I was hopeful that the damage was limited to just the headbolts. I got a set of ARP headbolts and have duly been trying to rebuild.
So after a quick wash and refuel - I had high hopes last Saturday that the leak free engine was going to be ok.
So after initial DTC resolution (new coil packs on 3 & 5) I went out for a run. It was enough to know that the engine is not good. I emptied the expansion tank of water twice on a short 3 mile run.
You can see here before I went out on the shakedown run that not all was well. Well it only got worse.
http://youtu.be/pcIpnMXX4fI
I ran a sniffer test (to see if there were combustion gases in the water). This was negative.
Turns out that through either miscommunication or assumption the refitted head wasn't checked (pressure tested), prior to re-assembly.
I think it is fairly safe to assume that with the age of the turbo (virtually new) and the fact that when the water feed was temporarily clamped, it made no difference to the water consumption that the head is cracked. On the bright side the bottom end seems sound enough.
So what now. Well I am obviously very disappointed with the outcome. This stuff has kept me awake for 2 nights already this week.
My situation is that I have very little spare cash due to the Euro downturn since last Nov (damned Greeks), a dying mother on the IoW, busy home life with 4 girls all under 3 y/o. The resulting lack of time plus a few issues with the house that need resolving, means time to work on the SSB is very limited too. I promised to take my family away on holiday this summer - breaks have been few and far between.
I can no longer keep the C70 out of the way at HLM, plus it is too far away to work on. I know that Hamish is not keen to work on it, plus he has no employees to assist. At the same time I don't want to admit defeat and despite Hamish's insistence that this will never work. So on the one hand I have a car that has been pretty unreliable for the last 2 and a bit years, I know my wife doesn't believe in it - I sit here trying to answer the question - "When did I last enjoy it?".
The issue is that I am not certain the project is sustainable or reliable enough with the current design. Clearly the turbo is capable of tearing the engine to bits. It has long since stopped being a car I could use regularly because I don't want to use up the mileage on knife-edge reliability.
The options are
Break the car for bits. Recovery of costs but fundamentally heartbreaking.
Sell as a whole/going concern. Unlikely to achieve anything like what it is worth in parts, particularly in a broken state.
Stick a sheet over it on the driveway. Limited tolerance from her indoors, but at least I could work on it.
Find a sympathetic mechanic to help get her up and running again. Expensive.
I am finding it very hard to give this up, but on the other hand does it really add up to a hill of beans. Will anyone give 2 hoots if I beat Dean or not? But there again does any of this matter??
Even if I fix it - will it tear itself apart again - or more over how long will it take to tear itself apart? Is the design fundamentally flawed?
I've looked long and hard for something I could get interested in and either it is too expensive (I don't really want to take on any more credit commitments ATM) or just not floating my boat.
I am fairly settled on not giving up just yet, but with all of this ^^^ bombing around my head every night - no small wonder I am not getting much sleep. I appreciate anyone taking the time given the length of this post
Most immediate issue is I have maybe 2 weeks tops to get the SSB moved to a new location. I'd rather not waste money moving it more than once. I think bringing it home is most likely.
I sympathise fella, its no fun driving a car you don't trust, especially if you've poured your heart, soul & most of the contents of your wallet into it. Have you thought about just returning it to standard? Remove your lump & custom DP & just drop in a standard t5 lump & DP [and probably the ecu]. Relatively inexpensive & at least the car will drive whilst you sort out the modified lump as & when funds allow - plus its easier to store an engine rather than a whole car :)
I wish you well which ever way you go but try to resist breaking it if you can, I think you may regret it further down the road...but sometimes needs must
All the best, Morgan
Wow, Dave. I really feel for you mate. We've sat on different sides of the fence on occasion over the last 10+ years, but the fact is we have know each other for quite some time now and it was actually quite hard to read what you put above, quite saddening.
First things first. As much as we all absolutely love our cars, and it is incredibly heartbreaking when they go bad (I've been there), it's just a thing. We all deserve and need our hobbies and interests, we work hard for it, but if something is dragging you down to the point where you're not sleeping, hemorrhaging money and feeling like you do, maybe it's time to pull the plug. At least for a while. Cover it up and forget it for 6 months.
And don't be daft enough to worry about the expectations of everyone. Whether it's running well or not, whether you're faster than Dean or not, whether your driving the 400bhp monster everyone would want or not... It's hard I know, I've been there. But in the grand scheme of things it all means nothing mate, and no-one will think any less of you.
If there was any way I could help, I would and I really mean that. I'm fortunate enough that I have Tim, I just hand the car to him and he does what I need, and he's never let me down in fact he has gone way above and beyond on many occasions. Without him I wouldn't be where I am now and that is a fact. I don't know if Tim is your answer? I don't know if there is too much water under the bridge, or it just wouldn't be a viable option for him to inherit such a job, or viable for yourself?
I don't know what the answer is Dave, but moth balling it and walking away for a while sounds sensible to me. Forget the car, get your sanity back and then decide down the road how you want to continue.
All the best with what ever you decide.
Chris I appreciate your thoughts.
Does anyone actually believe it will work or is this just some stupid pipe dream. I've had the "300 bhp car" for 6 years (& I confess I got a little bored). In hindsight perhaps this last adventure is flawed? But the 19T was shot - all used up - and the old engine was beginning to chew water. So either it was time to quit or time to push on.
I think now I would only push on further with a re-think on the whole design. 1.7bar is from experience perhaps too knife-edge?
It's not a pipe dream Dave. What you are after is quite achievable, it just needs the guidance of someone who knows what they are doing and how to get the best out of what you've got, not wishing to sound disrespectful to yourself, Hamish and others for where it's at right now. I have the utmost respect for the way you tackle a lot of the jobs yourself, I wouldn't know where to start. And it's not like you've skimped on cheap parts!
I don't think 1.7bar is high at all, let a lone knife edge for the turbo you've got.
Mapping is one of the biggest issues you face I think. Finding someone competent to cover that base would be the first bridge to cross I think.
Gutted to hear that news mate, I also have known you a fair amount of years now and we've had some great weekend's of racing, beer and banter :). By reading the above post is it solely the wanting of a new head that's now delaying the completion? if so I'm sure we could source one for you get Tim to fit it together and onto shark for mapping, i know it sounds simple when written like that and in reality it is funds allowing but don't give up mate.
I don't feel ready to give up, Jim just yet. There is a selfish core that says - how quick can I fix up the house issues so I can get back to getting it right? and feel quite guilty about it.
I miss the racing and the banter very much indeed, but without something vaguely competitive, what's the point of showing up. I've never been a good spectator.
For the very reason that you shouldn't be using a FWD Volvo on a drag strip, is the perverse reason for doing just that.
If I was to get into the 12s then would it matter? Probably not.

Rest In Peace
Maybe I should alter my will now?
Certainly don't want the SSB to become grounds for divorce and Ellen in her good grace has said that she will not make me get rid.
My 2 cents worth....
Family is the most important thing, and from what you've said I'm amazed your managing to get by as it is, without car commitments! I find life draining enough with just one toddler! So put yourself and your family first, draw a line under it and move on. Bring it home, break it, make the most money you can, enjoy life for a while and move on to a new project some time in the future when circumstances are better.
I've a 205 GTI in my garage that's sat doing nothing for years. I've never enjoyed (had 3 before it that were great) it even before it was taken off the road, it's been a ball and chain around my ankle for years. I hate the bloody thing, but at the same time I can't bare to see it sold for peanuts. It's always a difficult decision when you've got so much time, money, love (or all 3) invested in a car, but some times you just have to sever the ties. I'm probably about 99% of the way to making that choice too.
Just spend some time away from the car dave while doing the house and come back with a fresh mind and eager to get it right as said above I would seriously get in touch with Tim regarding it he's certainly pushing the boundaries with his set up and it's working he has some great knoledge of these engines and what works.
I am talking to Tim on T5D5 - I hope to put it to one side and crack on with the house for now.
Easy to say, but...is it not just a case of sticking that head on it from Barnsley Bill, getting it custom mapped + adding a dash of nitrous then 12's here we come? Family comes first of course though, esp when someone is ill (sorry to hear that). As Chris & Peter said maybe step away from it a little. 400 hp is still a good achievement though IMO.
The roller coaster that is the Oil & gas industry should be picking up at some point, maybe next year.
How much needs doing to the house Dave, is it just a case of a bunch of us descend on your house one Saturday, and do a D.I.Y. S.O.S. sort of job? If so, I'd gladly lend a hand, then once the house is sorted, you'll have more time for the family, and SSB.
Really sorry to read this Dave.
Completely understand where you are coming from with the family & low on time. I have 1 child so I don't know how you cope with your tribe.
If your lucky enough to have a daily I think your mad to get rid, in fact I think you would regret it when your wallet is flush & the kids have grown up a bit. Surely it's worth the ear bashing off the wife for a bit to get it sorted even if it's back on the 19t.
Problem is it will always find the week spots & will make it unreliable.
Me personally would want it reliable & putting a smile back on my face.
Dave - remember my 850 hasn't been on the road since 2006!!! I'm not giving up on it yet.. Maybe Tim is the way to go, maybe not.... But don't stress... Switch off.... Walk away for a while and don't even consider doing anything..... and if in the end it never gets done........ So what!!!! It was fun whilst it lasted.
Thank you all for your kind words. I am going to get the SSB transported to home.
As a family we do have a daily runner - many of you saw it at the last Shropshire meet. So the SSB can remain parked up - so there is no great rush to get the SSB back up and running. I am more worried that Dean will get bored and sell up.
I need to get the damp thing sorted. I've got a builder coming to look in a couple of weeks. The big headache is the artexing. Whole house is covered in it, save the bathroom & Kitchen and Ellen wants it gone. Not something that can be resolved in a weekend. Salting under the artex has pushed & cracked it off in places.
maf = underscaled load = huge timing and knock on your aet map....
log it properly you will see, good luck
