Rod's build thread - new title - TSCi
Turbo Mini Forums

I,m with Rod on the idea of not having an obvious dump valve and, on his recommendation,I have a Saab valve.
Still hisses pretty loud though.

Actually fast dual-spring DV don't pshit, they just 'psst' very quickly and only when there is a lot of pressure. It's just much simpler and may be as cheap as recycling system as they don't need return path and silicon hoses (not needed BTW).

one thing that suprised me is the noise my recirc dump valve (that just vents to air) makes, with the boost up its a proper loud CHHIIING! with a really metallic ring to it.

I'm impresed with the dump vavles with a filter round them, seems to really take the edge off.

Single spring DV have softer springs and can not stop leaking below some level of boost, they leak as long as throttle is released.

Interesting comments - my intention is/was for it to be as quiet as possible.....

It's a common Bosch item, used as OEM by many manufacturers, same as on my Cossie. It's quiet enough on the Cossie, not silent obviously but not intrusive, the wastegate is louder. But Ford have it closer to the turbo (shorter re-circ path) and further away from the air filter than I can achieve in the confines of the Mini. Also the Ford air filter will be a much better silencer than a cone type.

Without dismantling it to be certain, it looks like twin pistons with the actuator piston being about twice the size of the valve piston. So with the sense line from the plenum, while the engine is under boost it is held well and truely closed just on area ratios. It's certainly leaktight on the Cossie at just over 1bar.

But as this whole setup is a "one off", we'll have to wait and see :)

Schrödinger's cat - so which one am I ???

Decision time...

The Chinese one (see here http://www.turbominis.co.uk/forums/index.php?p=vt&tid=371421 )



Or the Ford (which will fit better if I modify the end tanks).

Can you pressurise them both and see if there's a pressure drop across them? That'd give a good indication of which to use I reckon - they both look as if they could cool adequately.

Just done a crude (but quick) test of them both

Finally managed to cram it all in....



Intercooler is centre to clear the Clubman front headlamp bowls etc.



I've ordered another bit for the last (or should that be first?) connection to the air filter. 45 degrees is wrong, so is 90..... but no-one sells 60 degrees.

So flexible from now on...



And room for an oil cooler if needed.

Looks really smart rod!

It's certainly getting there, keep it up Rod

Well after a few weeks of no motivation, I finally connected most of the engine management mechanical bits...



I had to modify the plenum yet again to fit around the turbo outlet



Home made playdough to check the clearances everywhere.

And then the next problem



Fuel pressure rgulator in way of turo outlet.

Even when the fuel pipes are in their correct position, there is still a conflict



But I have a plan.

Nearly there...

The new title (TSCi) is because virtually every car on the road has a four letter acronym nowadays.

ie, my Mondeo is a TDCi (Turbo Diesel Common (rail) injection.

So mine is now a Turbo Siamese Code injection..... (TSCi)

glad to see your finaly motavted again rod :)
any updates on the other shell

Drop A Gear An Floor It

Steel arrived today for all the mounting brackets for intercooler etc..

A bit too much but it was actually cheaper to buy 6m lengths than 3m as the price difference was tiny and I reached the "free postage" threshold...

Put all the wiring in today....



What a mess.....

And from inside



But the major setback is with TunerStudio.....

What really pisses me off is they keep upgrading the software and half the versions don't work...

Today I hit another not working version.... and as you can possbily see from the photos I'm extremely rich but I can't reset the "req'd fuel" value..... (rich because I put bigger injectors in).

Having said that, it started third attempt and both the abortive two attempts were my fault...

Your seat doesn't look very comfy...

just looking at your pictures an thought why dont you move the water bottle to the outer side of your inner wing (whats left of it) give you abit more room

Drop A Gear An Floor It

No more pictures or logs (I'll post them in the other section soon) but I got all the software working again.....
For some reason Microsoft said TunerStudio wasn't working because of a problem with Java ( I assume it is a Java application) but I couldn't re-install Java as java.com was down so I re-installed TunerStudio and it all worked again.....

But every time I go to try and optimise the setup (I've fitted 1000cc injectors now) it pisses down with rain.... The Mini has to be outside the garage to run it safely because, apart from the exhaust CO2 and CO, it's too close to the wall inside the garage to get at the laptop and MS...

I was thinking of coming to MITP (obviously not in the Mini) but with this weather I don't think I can be bothered.

Andy (banned???) I do have some proper seats....

Aiden I tried outside the inner wing but too close to the wheel on suspension travel, I've now figured out a way of cramming it in, just need some new parts to arrive for the FPR plumbing.

The intercooler bracketry and mountings are going to be agricultural with that amount of steel

just a quick question how much more power will you get from injectors aposted to carb as seems a lot of weight with all that wiring and hassle cus i hate wiring and computer saying no lol

I like the brace bar. and looks like there might be room to fit a crash bar like the Z cars one.

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!
