I guess it stopped working when Nick pulled the fueltank out :)

hmm i don't know, but that's a good question.

 

hydraulic handbrake conversions would probably get a bit cheaper if we new ;).

 

That is exactly what I thought. So anyone who knows??

Come on maybee a Volvo PV 544, what I can remember

on these cars the master cylinder was mounted behind

the brake pedal. And I can hardly think that they have

noting else than a one way ( I don't know what's the name)

but not a two wy system as newer cars. I hope you understand

what I mean.

pugtorque & Hilgie> hehe yeah, fuel tank and fuel pump are out and will

be replaced by a custom aluminium tank and external 405 fuel pump,

which has to be wired in, new fuel lines plumbed in... and the enigne

hasn't ran for several months. and that's after the new large radiator

and exhausts get installed... so you'll be looking at a few more phases

before the beast hits the road, in any form :DB).

 

 

Clarre> yeah i understand, you mean a sinle outlet port instead of 2/3/4.

it also has to be very small, 0.625" which is about 16mm. we actually tried

to make a hydraulic handbrake many years ago, using a 1.6 master cylinder

with 2 ports blanked (so there's only one outlet). we blocked the rear brake

lines going from the car's master cylinder and connected the rear brakes

only to the 1.6 m/c that has had it's own reservoir. it didn't work out though,

not even with the servo installed (but it was a funny sight anyway ;)).

Still an awesome build and startling progress :unsure:

 

One radiator? :( Wow - I'd have thought that possibly two independent radiators may have offered another alternative with ducting run from perspex rear quarter windows, back to a rad located near the back engine.

 

The early Elises used to suffer from thermo-shock issues for that reason, the radiator was mounted so far away that the coolant circuit would open, the very cold radiator coolant would rush into the engine, meet the thermostat housing and shut the thermostat at which point the process was repeated... again and again. It was not a steady flow of coolant mixture around the engine & radiator. I'd be concerned that having two engines (one fully enclosed in the back of the car) would compromise the viability of a single cooling system.

 

However I appreciate, Nick, that you have not gone the space-frame route and that with the exhaust manifold being at the very rear of the car, mountin a radiator with a fan isn't really an option there and, I'd imagine, to mount it in the normal loaction of the XS front end would probably mean it is too far forward to benefit from an airflow from the rear quarter windows or a scoop mounted forward of there...

 

Awesome build though :(

I think Findlay has a point, I'd try to use two radiators. One for each engine & have a thermo switch for a fan on the rear engine so it switches on when the engine is running at the desired temperature swapping to higher speed when the temp hits another preset temperature.

 

You could take the heater out then as it'd be plenty warm enough inside then. :)

well we had gone for a single large radiator (and all the problems that go with it) for now, but we'll see...

 

it's not possible to duct anything from the rear qtr windows, as the engine will be enclosed like in a Clio V6.

 

side openings are small and one is for the airfilter while the other is for a little bit of airflow in the rear engine bay.

 

there's no space in front of the engine either, as the fuel tank will sit there and take all the space.

 

so maybe only behind the engine, with fans drawing air in through the slated tailgate, but not sure how effective would that be?

 

thanks.

gay pics :rolleyes::blink:.

 

that's an intercooler though, not a radiator.

 

what car is it anyway, looks like a nova?

BTW do you know what cars who use the Girling 625

Master cylinder?

 

Girling are owned by TRW at the moment and I have asked them, but I don't expect a response.

 

So far I've found out:

Hillman Imps

Land Rovers (maybe just the 1970s ones)

(Triumph?) Spitfires

TR7s and TR8s

AH Sprite and MG Midget

 

I think they mostly use them as clutch MCs, not sure if that's useful or not.

Onthe rad question, what about 2 smaller rads? You could have different thermostats in them to negate the thermo shock effect so they kick in in series, not parallel

Couple of ideas.

 

the way a guy in PPC did it with a Alfa 155 although its a saloon, he mounted it on the boot, with vents there.

 

Or the way i remember seeing a Mk1 fiesta at a ford show mounted it just behind the front seats with cool air from below.

Stick the back radiator in the roof with a small scoop covering it!!

And hope that the sysyem doesn't leak! That might create pressure in the engine while its sat idle... That might not be too good for head gaskets etc... Centre of Gravity too - although granted not so important on a 1/4mile car.

I can see in your pictures that ypu intend to have a lever to cut off the clutch hydraulics to the rear engine if you only need to run the front one - but what will you do about the rear gearbox then? As I see it, you have welded the shifters for both front and rear together.. If yu plan on occasionally only using the front engine, you need to be able to leave the rear engine in neutral- and shift gears on the front engine ;) have you thought about that ;)

rear gearshift linkages can be seperate in a few places, now you mentioned it, but it doesn't matter.

 

it takes only 10 secs to pop one or both short rear gearbox rods off and have only front-engine shifting action :D.

 

we're going to make it switchable from driver's seat though, later.

sorry for the long delay, due to a computer crash, data loss and recovery and

system reinstallation on top of having a lot of commercial design work to do!

 

 

Phase 4: Coolant Radiator & Exhaust System

 

Phase 4 story is all about fitting a large customised radiator:

 

205Mi32_Ph4_009.thumb.jpg

 

and constructing both front and rear engine exhaust systems:

 

205Mi32_Ph4_034.thumb.jpg

 

so we could start the front engine next.

 

 

you can find the story (with 40 pics) on THIS PAGE.

 

this time it only took three full days of intensive work to complete the phase :D.

 

 

stay tuned for a short video and then Phase 5 of the 205 Mi32 Project!

 

 

thanks.

after completing front engine's cooling and exhaust systems, we hard-wired an external

405 fuel pump to start the front engine after several months of being out of use...

 

205Mi32_Ph4_040.thumb.jpg

 

it started without problems, apart from expected noisy hydraulic lifters.

Looking good. B):)

 

Thats one hell of a death rattle though, hope it fades away.

 

Has the head been apart or is it just from being stood so long that the oil has drained out of the lifters? ;)

yeah as i said, it had been stood for several months, so noisy tappets were the least we expected.

 

oh and the rest of the noise is exhaust manifold related.

 

the tappets have quitened down since btw ;).

Phase 5: Rear Engine Electricity & Cooling

 

this is the first part of the Phase 5 story, where we tackle rear engine's wiring:

 

205Mi32_Ph5_004.thumb.jpg

 

and start plumbing the coolant pipes from the radiator towards the rear engine:

 

205Mi32_Ph5_023.thumb.jpg

 

you can find the first part of the story (with 25 pics) on THIS PAGE.

 

 

stay tuned for the second part of the Phase 5 story!

 

thanks.

Keep going dude - not far now.

 

As for your first picture at Bos Gradiska (spelling?) - sorry about the clutch by the way - I used to drive over the Hungarian engineers' rickety old bridge there and on into Croatia before that shiny new bridge was built in 2000. How time flies! :unsure:

well you seem to have a pretty good memory :lol:.

 

the bridge has a rather nasty pothole in an awkward place btw :unsure:.

I've just checked - my truimph gt6 (similar to spitfire) has a pair - one brake, one clutch.

in the second part of the Phase 5 story, we continue work on rear engine's coolant system:

 

205Mi32_Ph5_027.thumb.jpg

 

and after testing the wiring and all the sensors, we get the engine started:

 

205Mi32_Ph5_047.thumb.jpg

 

you can find the 2nd part of the story (with another 25 pics) on THIS PAGE.

 

 

with work being spread over a few months, Phase 5 is finally complete!

 

stay tuned for an exciting video of starting the rear engine! <_<

 

 

i want to wish all the members of this forum a happy and successful new year

in health, love, business and ofcourse... 205's! <_<

 

 

thanks.
