Me too and I've only seen it in pictures lol.

Nice one Dave!

Love the pic

Perhaps some kind of electric shock method instead of the accelerator 'stick'?

Just need to install the accelerator stick through the firewall.

Best place for Tom.. In a caged environment!!!

I see - sticking with the electronic rather than the manual throttle.

Yep, though the software update might cost a bit...

I have changed my mind about clipping the 19T - so it will be up for sale soon.

I love it when things I've spent ages thinking about come together, particularly when they arrive.

T3 headache solved - no manifold welding required.

5 bolt - V-band adapter should make it fairly easy to adapt my current 3 bolt d/p
I am more than a little bit excited about this now.
More parts/secrets will be revealed later.

Lovely shiny things there Dave.
I can't help thinking though, You may be a little past needing a Haynes book of lies to assist you in your efforts. When looking up info on the turbo in my Haynes, all it says it refer to main dealer

Dave sent you a pm mate :-)

I had thought originally going for this option

with a secondary "screamer" pipe...

but I think that may be a bit OTT for my application. The idea being the back wash pressure from the main exhaust gas will interfere with the operation of the swing W/G valve, but given that I would have to rejoin the secondary back to the d/p before the cat (so that the 02 sensor gets a proper reading) I didnt feel it worth the hassle. Well that's my theory.

So instead the v-band option seemed easier to deal with...

Aren't screamer pipes banned from road and track use?

**Wobbly Dave** · Thursday 8th November 2012, 13:32

Yes I believe true screamer pipes are. Mine would have been something like this...

**jardon** · Thursday 8th November 2012, 14:32

Awesomeness - how much extra would it cost to go with the screamer pipe option? I've been reading about the down sides of wastegated gases merging immediately in the turbine. I half understood it.

**T5frankie** · Thursday 8th November 2012, 14:39

I'd better pull my finger out lol

I think the principle would be that as the exhaust gases leave the turbo, there could be a tendancy for that back pressure to push the swing valve shut - making the actuator less able to control the wastegate. As far as I can tell the separation of the main flow & the W/G flow will only work if you have a proper screamer pipe, which does not re-join the main d/p.
I would have to find someone to custom weld the pipes up & TBH having them join up 6 inches further down doesn't seem worth it, plus the V-band option gives greater flexibility when it comes to orientation of the d/p flange. Lobbing off the old 3 bolt flange & tig welding the 3" V-band adaptor is relatively easy.

If Betsy was a race car then I might have gone the other way.

The fact the WG is somewhat separate from the main flow will have to do.

**jardon** · Thursday 8th November 2012, 17:50

I think you're right - maybe not much gain in having the pipe join a few inches away.

Very nice Dave wot map u going for then?

i think it'll be quite conservative to start with. i have a snabb tcv and we'll see how well the boost can be controlled. main issue is the speed the ecu can react with the car equivalent of windows 3.11

**Wobbly Dave** · Wednesday 21st November 2012, 00:58

Well - I have finally bolted the V-band housing onto the turbine housing & bolted the whole thing together. What can I say... it's quite big!!

Main issue is finding the time to fettle it all. I need to sort out the circular lip on the manifold - get the CHRA properly orientated. Then I can start getting the oil feeds etc sorted - and get an actuator for it.

Long way to go yet!

**Wobbly Dave** · Wednesday 21st November 2012, 19:39

Sent the S60R manifold to be skimmed and have the flange flattened today. I notice that ATP do a special flange conversion for the T3 to all for the raised ring - but it'll be more expensive to import, than to have the machining done.

I am more disappointed no-one has said owt about the new blower..
