ok, i learned a bit about this earlier...

do you REALLY need T6 or an equivelent ECU to run it?

it sounds a lot easier to do than your usual ALS, and also less harsh on the engine

what vales do you need to use, where / how much are the buggers lol

plus anymore info is good lol

i read stavs post btw, so ta to markk and si

 

so no cunt knows....


charming

 

You posted it at 11:43 pm on a friday...



Its now 1:20 am , people have lives outside of PF you know

 

really?

well, in all honesty,

they FUCKING SHOULDNT!

everyone that knows anything should be on here 24/7 and thats that!

no if's, no but's, i want answers and i want them NOW!

they should all drink from home like me!

 

you do need a half tidy ecu to get the type of control needed to run it

its alot more complex on the control side than normal als

theres loads of types of valves you can use,,, i believe if you look about you could build the set-up for about 150 quid

 

no matter how many times im told about it, it still confused me

so the pressure in the inlet side is always more than the exhaust manifold, so the gas cant go the wrong way?

is the valve just open or closed like normal ALS, or?

i dont totally get it, i suck

 

the valve isnt just opened or closed on a normal ALS system steve

egr als, feeds air from the outlet of the compressor into the inlet of the turbine, add a little fuel from the engine, and you turn your turbo into a turbine engine,,, but its not thrust that we use just the shaft speed/ energy

 

isnt it?

i know EGR does that mate, buti cant get my head around why exhaust gas dont go thru to the inlet side rather than the other way round?
is the pressure on the inlet side always higher when off throttle? 1way valve? what?

 

just so people know what we are talking about

 

off throttle, there will be very little pressure on the inlet of the turbine

as soon as you get the egr working, there will be alot more flow from the outlet of the compressor

 

ah cool, i didnt know how much pressure off throttle there.

makes loads of sense now

how/why is it less damaging than normal ALS? heard things like that, and it creates less heat?

but then, if you believe that forced induction tuning book, Ferrari F1 first used it, but had to stop and revert back to normal ALS as the EGR setup was more heat, not less?
but there a few "facts" in that book i know are wrong, so that may be too.

 

i "think" the reason why its less damaging than normal als, is because less high pressure shocks are produced,,, im not 100% on this though

 

cool

whats the deal with a "suitable" "EGR" valve? someone (you?) said something once that a part from a Supra or something was used or useable?

 

ya mate,, ive heard the mountune valve is a supra EGR valve

 

So, who is going to have a go at making a full set up then?

 

To be honest, the term EGR ALS is actually wrong in this context as the exhaust gas isn't being recirculated but is actually being used in a similar fasion to a normal EGR type system.

 

yeah, EGR is a funny term for both processes.

 

I might have a go at making one later on this year if I get round to it. Unless someone does it before me and can sell the kit cheap!

 

ive been tempted to have a go,, but i really havent the time needed to bang into it

maybe they call it EGR ALS, because they use standard EGR valves,,, or maybe because they use the exhaust from the compressor

 

BTTT for fudgey and his gurt lush where you to inbred comments

 

PMSL

 

steve you cunt at least i dont shag my sister you inbred fuck

was finishing off the kitchen yesterday, after i got up at 12 due to a fookin headache

anyhow, gareth, if you give a full breakdown of what bits are needed that would be top.
i like your pic and all, but fook knows what the bits are

also, can SECS S8 run it?

i have one of them, and im gonna use it... no matter what (i have no money for anything else, and already own it lol)

if not, then i guess this post is to be lost into the realms of PF for ever

cheers for the replies all

 

theres the egr valve itself
two solinoid control valves (one to open, one to close the egr valve)
a cylinder for storing pressure to operate the valve
a one way valve to allow the cylinder to pressurise, this is charged by boost pressure
some bits of pipe

 

cool cheers

and will it work with S8?

and where you get the valves to?

 

Dan

I have this on my car. You are welcome to have a look!! I know it allows ALS to be run at a slightly lower temperature and keeps the inlet system pressurised constantly - there is a small metal cylinder on the front of my engine which is compressed at all times.

The concept is to help reduce lag whilst keeping EGT temps down. Plus it looks bling and baffles the chavs

Not sure what ECU's will run this but the T6-2000 has dedicated menu applications to support and control this particular application.

I am currently in talks with a company to take my system off (which is not a Mountune system by the way!!) and remanufacture it at a reduced cost! Will give more details when I become a trader on here

 

not sure about the s8 as standard,,, im sure simon could program an output but of cause thats up to him

your useless aint you,,,, look in rs for 1/8 3/2 valves,, solinoid operated srping return norgran valves

 

Gareth you cooont - you beat me to it

 

hi ian,,, i think your car is the only road car with it fitted

 

your too slow ian

 

Lol... My only claim to fame!

 

One thing... Mountune charge Ł2795.00+vat for the relatively small amount of bits in Gareths picture! And that's wihout the ECU!! Is it worth this money? (Ł3248.00) ...... I think not!!

I think mine uses a valve off a Toyota or Porsche IIRC. Can try and find out?

 

Ł3.5k for some pops and bangs and a fast as fook car

jeeeebus!

ian, it would be very cool to have a look at your car sometime, ill let you know when im next over your way!

im only in swindon so not far at all

cheers gareth, sorry im not as clued up as you are

 

Never used it but from people who have, the mountune one aint that good anyway....it relies on vaccum to open the valve...The focus wrc one is just a housing with two ports, spring tensioned valve and a dirty great solenoid coil controlled by a solid state relay. The relay coil is fed from the T6 and hey presto....the EGR is worked in conjunction with normal ALS stategy but with less aggression so less heat. When open the egr sounds like an air leak into the exhaust....

I doubt S8 could run it (on a hardware level) although I might be wrong. There are 2 valves that need to be controlled independantly of each other which means 2 extra outputs are required. The S8 and Weber stuff only has a 35 pin plug and most of them are used already!!

 

So going off that, the EGR ALS valve is just opened and closed rather than varied in position?

 

ian you havent got a photo of the focus one?

just thinking about it,, you could use a smal external wastegate as the control valve if you put a bit of effort in

 

Dazc,

The old S8 has plenty of outputs as standard.
It can drive 8 injectors out the box and as Dan has only 4 injectors.....
Also has 4 user outputs which can be used.

The software doesnt support it but thats an easy mod.


Dan,

If you want this done no problem.
I have never set one up before so may need some input from Stu/Karl etc.,,

 

Daz,

Yep, sure is...

Gareth,

I have some but I aint at home, i'll post some during the week...its not complicated in the slightest.....

 

nice one ian,,,

simon do you have als control working right on the s8,,, i think all you need to do then is set and output high (100% duty) whenever the als valve is activated

 

Thanks for clearing that up Simon.
