Interesting thread.
A bit of tidying together with further technical input would make for an excellent technical read.

Mike Rainbird

iTrader: (3)

Totally and utterly agree .

Also, I will data-log the ALS on and off boost / rpm profile and report back as soon as I can .

Stavros

On your ALS setup?

Utterly pointless IMO as even your "in the boost threshold" data will make ALS look fairly unimpressive, never mind that.

Mike Rainbird

My latest ALS set up features the same air bypass arrangement as used on the Mountune works Grp A / WRC cars .

But even the old arrangement was aggressive enough for 0psi at idle (same as Stu's set up on Steve Whittacker's car as per his ALS thread) and that still caused temps of 1100°C when used in anger on track.

I can confirm, that after reading all 6 pages, God is weeping in frustration that he gave his only son for mans salvation, and its led to a topic like this.


Shame on you.


Baby Jesus is gutted

Stavros

And? As you damn well know, you using a MUCH bigger turbo than that was intended for, and ALS is also down to the amount of fuel and retard, ie can be made milder or wilder even with same size bypass

Mike Rainbird

See my edit before you posted.

Stavros

1min AFTER according to the edit, beeeeatch

I dunno, maybe its just me but after having very effective ALS, i dont see the point of having anything less.

Never understand this "i get 5psi at idle stuff" tho, means nothing. I never got boost at idle (ian/racetek did, a good 7psi on the T34), but i could see anything up to about 29psi boost on the overrun!

Mike Rainbird

Give me a chance to type you muppet .

You'll have to come in the car and see how "ineffective" it is then .

funniest post in this thread!

Physio

Hilarious reading all the funny quotes against Mike for a change

Chip

iTrader: (3)

You must be properly relieved its not directed at you for once stumpy.

Physio

It certainly makes a refreshing change Chipston

Benni

Maybe one day I will take the time to explain it all to you. I do agree though the article was a fantastic read like all of Stu's have been and very informative for us dumb lot..

Mike, Seeing as you are so good at this stuff why don't you do one every month about handling? Would make a good read i'm sure.

Ste whittacker sold his car as it was too fast for him , so we won't be hearing much more about it ....

the launch control coupled with ALS was most effective though

Mike Rainbird

iTrader: (3)

I've done an article every month for the last six or seven, and one of those fully encompassed handling (with regard to Cosworths) .

Mike Rainbird

iTrader: (3)

Damn and blast, as it would have been good to compare notes + what a pussy .

Mike,
Do yourself a favour and edit the thread title. Do you know the term "Professional Courtesy".

Stu,
You blithering fool you know Mike is NEVER wrong, so why use facts and
experience to prove otherwise as it will make no dent on that ego.



PMSL @ Fagin

Mike Rainbird

iTrader: (3)

I'm often wrong and Stu often corrects me with exact facts as to why I am wrong. I have no idea why has not chosen to do so on this occasion, as it would complete the ALS jigsaw and once edited of the purile comments, would make a very interesting thread.

Of course this is why i was enquiring about bigger turbos for more power you will of coures recall, Which Mike you posted on and made a suggestion for me if you recall
If all goes to plan this week then i may have something within the next few weeks for you to compare to if you want

Mike Rainbird

iTrader: (3)

I take it Will was just taking the piss then .

So what's the plan Stan?

4x4 ste

Nothing is concrete yet as it depends when i move house but there are a few ideas on the near horizon

ECU Monitor Enthusiast

Mike Rainbird,

Have to say, you fight your corner well and I congratulate you on that

Very much like myself

4x4 ste,

Cant believe you got rid of that beast....

mike that last two vehicles that we have mapped ALS strategies to have been with T4 cores and GT30 comp housings/wheels

so i hope you are learning from this post pal.

unless your talking bigger than that - then i have no experiance, and i will apologise.

Benni

Just got down to reading your article about cooling mate and I enjoyed reading it.

the original

that was a bit of a read for a sunday morning

surely some ALS can bring the boost threhold down by 2 methods
retarding the timing to produce more volume of hotter exhaust gas
and igniting between exhaust valve and exhaust wheel in turbo thus bringing the turbo in at an even lower rpm
much the same as proper launch control
if that's not lowering boost threshold I don't know what is
depends on who set the ALS map up though

Mike Rainbird

iTrader: (3)

Stu,
The thing I can't get my head around, is that as soon as you get back on the throttle, the ALS disengages, so there needs to be sufficient energy in the turbine to over-come the inertia of the turbo and keep it spinning sufficiently until it reaches the boost threshold and the energy from the exhaust gasses takes over.

You could obviously run heavily retarded maps below the boost threshold to try and bring on the boost (a kind of constantly engaged ALS), but that opens up a whole area of discussion completely seperate to switchable ALS and would cause HUGE heat related problems (turbine blade / exhaust valve failure). Not to mention the potential power sacrifice -v- bringing on boost earlier so that you can get to a "normal" map ASAP.

I wish Tony or Stu @ MSD would shed some light on the subject .

Redkop

Maybe Sheady could too, as all the Autronics he fits have ALS and he's fitted loads.

4x4 ste

To be impartial in the case why should either one of them give up there own valuable time to explain something on here for free Surely a good mapper has there own idividual ideas about something like this and would not want to go sharing years and years of experience and learning that makes the difference from a good mapper to an average one Just a thought

Mike Rainbird

iTrader: (3)

Steve,
I'm not asking for figures or map values to be revealed - just basic principles of how it is achieved .

Physio

Mike, are you surprised Stu doesn't want to shed any light on the subject for you after you tried to make him look silly?

Mike Rainbird

iTrader: (3)

AJ,
So no-one is allowed to highlight something then - it must be left as being misleading?

I'm sure people have a short memory, but I took the that Stu handed to me when I mis-worded my explanation of pressures and flow regarding turbos of different sizes . I didn't get the hump, I just fought my corner and got put in my place with a rational and logical explanation by Stu - I was more than happy to accept that ? (And no, this isn't retaliation, as that must have been several years ago , but it just seems no-one must question anything if it is written by certain people ). I WANT TO LEARN - the only way to do that is to question everything you don't understand and accept nothing until you do .

Turbosystems

iTrader: (5)

I believe stu and I have but you seem set in your mind that als can't alter the boost threshold yet launch control can, so is there any point in us spending a huge amount of time trying to change your view.Perhaps Stu may include this in his next feature in the mag and no doubt you will challenge it on here again

Mike Rainbird

iTrader: (3)

Tony,
Obviously you can't read you old fucker, so I suggest you go back and look again and answer the questions I asked about LC (and while you're at it, the ones about air injectors as well ) .

Chip

iTrader: (3)

Its not because you questioned it, it was the manner in which you did it.

Im surprised at you not having more tact and professionalism Mike.

If I could see it was out of order, and im about the least PC person on here, then you should have been able to.

Turbosystems

iTrader: (5)

Y mike are you saying that we have to read your long winded posts and answer each point specifically and explain in no less that 5k words the reasoning behind our answer because you are Sir Mike Rainbird.
I will do it now for you

















NOT

Chip

iTrader: (3)

Mike, cant you just phone harvey and ask him?

Mike Rainbird

iTrader: (3)

Chip,
I sent Stu two PMs apologising at causing offence and making it clear that it wasn't my intention to upset him, and asking how and what I needed to do to adjust my post accordingly. He STILL hasn't even read these (despite being aware of them).
