I'm looking for a bit of advice with the down pipe/ Turbo exit pipe or whatever you like to call it.



As you can see from the below piccies, its all a bit tight and my concern is that I am getting too close to the brake limiter valve and brake pipes, and perhaps the clutch pipe.















Looking through photos in this thread http://www.turbominis.co.uk/forums/index.p...tid=134918&fr=0 in most instances the brake pipes appear even closer than I have them at present.

I'm planning some sort of heat shield for the limiter valve, pipes and master cylinders and I can possibly move the Turbo another 25mm further forward and outboard. I do not want to extend the Manifold runners too much more. They are current 650mm (25.6") long already.

Ideally I'd like to tilt the exit pipe which is connected to the turbo down further to reduce the angle of the bend as it meets the down pipe, I think this would have the effect of moving the exit pipe away from the brake pipes, but would also bring it closer to the inner end of the limiter valve...

So, Will the heat from the exhaust, which will be wrapped, be too hot as I have it jigged up?



Its all only tacked up at the moment, so before I start putting it all together properly I want to make sure I'm not causing myself a problem.

thanks

Graham

I decided it was too risky so relocated the PDW and took the brake pipes out into the wing before bringing them back in lower down. Also ran a braided clutch pipe the long way round.

We did the same as Paul on Wintersurfer's side mount.

looks almost same position as mine although i got it a bit closer to the engine. and closer to the rear. just re positioned all the braking components away from it ( belgian car so maybe easier to move it all)

you can do anything if you set your mind to it...
i rather blow it up winning than keep it together losing.

finish date set for project 1... march 2018

Perfect Thanks all.
I think that’s definitely more sensible than how I have it at this point.

This would mean that I can change the turbo exit pipe slightly to get a more gradual sweep out of the turbo. It should also allow the removal one of the 45deg bends on the down pipe and the inevitable 90deg bend I would need to use to join the 2 sections in my current configuration.

I found that a pair of 80 degree bends works just right, even at 2 1/4".

Much happier with this:



I think I will take a further 5 – 10mm off the pipe at the turbo end so that the pipe is just a little further away from the bulk head.

I now just need to figure out where to put all the brake/ clutch parts I’ve removed. I cannot put them the same as the above examples because of my bulkhead wiring connectors and alarm siren.
I also need to figure out the route for the sample chambers and whether to move the 3rd wideband, pressure and temp tappings from just behind the gear selector to just above the diff housing on the down pipe…

In belgian cars everething sits on the left side. And there is a bar for the later remote servos but it has a 1 to 1 ratio to the pedal. So maybe use one of these to move it all to the left. ( here it is to get the left side pedals work on the right hand side but posible to make it work other way around though. )

And as for space. Im closer to the bulkhead then you are. So hope mine will be fine when running with adition of heat wrap.

Finally I’ve managed to finish Phase 1 of my remote turbo setup, so I thought I’d share a few pictures of how it ended up.

(Please excuse Welding, it took a long time and a lot of gas to get the hang of TIG…)





































I've only done 30 or 40 Miles so far on low boost (5PSI ), but it all seems to be holding together and runs OK.

*frown*

Phase 2 will be a new Inlet manifold with staged injection so that I can get back to some reasonable power...

Great stuff *happy*

What sort of ranges are you getting with the dual widebands and EGTs? Any correlation between the two?

Thanks for the positive feedback.


Hopefully it will all work long term. I’ve just not had much time to get out and drive since getting it back on the road a few days back.

The only major issue I have had so far is that the cheap ebay fan I have is just not man enough to keep it cool whilst ticking over and stationary. I’m hoping the new Comex fan that I ordered yesterday will help.
Once moving I’m keeping a steady 81 – 84 Deg, though again, I’m limited on boost ATM, so how it will fair once I get back up to 18PSI I’m not sure. Though I have made provisions for an auxiliary radiator, if necessary.
Also, Manifold air temperatures are a bit high. On average they are around 18 – 20 Deg C above intercooler outlet temperatures, so I need investigate whether that is the Intercooler to Throttle body pipe’s proximity to the Radiator, or whether it is due to the inlet manifold soaking heat from the exhaust manifold.

At the moment, AFR’s are all over the place. I’ve removed my original inlet manifold and modified a standard MPI manifold with only 630 cc/min injectors.
Hence the limited boost.

The design of the original inlet manifold, I think, was causing me to use some very odd injector timings and causing temperature related issues – I believe the angle of the injectors was tending to bias fuel delivery to the outer Cylinders whilst staged injection was off.

I say I think, because until I get some decent road time, I’m not sure if the issues I experienced have gone away. Initial logging seems to suggest they have.

The thermocouples have only been used up to now for monitoring the temperatures in the sample chambers. I’ve never actually monitored the exhaust gas temperatures directly in the manifold.
The main reason the thermocouples were added was because I was eating my way singlehandedly through the UK stock of 4.9LSU’s.
Turns out most of the issues with the LSU’s were related to the Innovate LC-2 controllers. Once I ditched them for the 14point7 controllers I’ve not had a single LSU failure – so far…
The highest Temperature I have seen in the sample chambers with this new manifold is 242Deg C for the inner cylinders and at that moment the outer sample chamber was at 182Deg C.
With the old exhaust Manifold the most I was seeing in the sample chambers was 250DegC, even at higher boosts.
But I think I can account for the higher temperature in the sample chambers on the new manifold because I deliberately made the pipes from manifold to sample chambers shorter.

I have LSU bungs in the main exhaust manifold branches to put the LSU’s directly in stream before turbo for testing, but before I do that, I intend on putting the thermocouple and pressure sensors into those bungs to get an understanding of the environment.
