Adjustable boost
Discussion
Didn't someone here have a boost controller fitted? Anyone remember who ?
I am going to be trying a few things out on my car soon (nothing bonkers!). All will be done fairly scientifically on a dyno dynamics rolling road measuring air/fuel ratio etc.. so perfectly safe ;)
Just fancied a bit of a chin-wag with someone who has done this or considered it.

Yep I heard about that !!
I am looking for something that is switchable but safe to run for longer periods of time.
Having a fair amount of knowledge on mapping if what they offer is say an overboost setting or 'scramble' boost that is switch operated is this simply a boost increase or is the Ecu remapped for both ignition and fuelling to suit?
If its just a boost increase and its not remapped I can only draw a few conclusions;
1) The car would be detting its nuts of all the time it was running the high boost
2) The engine and map can take this higher boost without detting - therefore one could argue that you could run that level permanently without detrimental effects on the engine.
At the end of the day a decent electronic boost controller is in the £300 to £450 bracket and are infinitely adjustable - thats kind of where I am erring toward at the moment.
Anyone else?

Go to www.nobleforums.com/ - one of the US guys has a boost controller plumbed in. Dunno how much he's played with it, but they tend to me more experimental with the cars out there. Probably because they are more of a kit for them!

That is likely as is the fact that the motor is $5200 to your door! As a long time Porsche guy that is an absolute bargain for what is essentially a race prepared longblock. Hell, a quality rebuild on MY 951S was $3600 and they didn't even replace a whole lot it there! What is a GT3 motor worth $40K US IIRC?
There's something in the blood that makes you want to make little tweeks here and there !!
Don't worry mate, she is being very well looked after - unlike the guy who just bought my much modded Evo6 who e'mail me to say he has just discovered why the car was noisey and jerky to drive - he had the anti-lag switched on for the past 2 days !!!!!!
All the best

New turbo time......
I've been thinking about ALS and water inj for the Noble. The ECU will run the water, but as there is no Idle valve don't think that ALS is possible. It used to be fun having the ALS on on the Escort and scaring the hell out of people. Issue with water is where to put a large tank to keep it in.
Yep if he's not careful !!
As far as antilag is concerned I don't think its a feature that can be mapped into the MBE ecu's unless you have / are going for a different ecu. Regardless of whether there is an idle speed control valve you could buy a throttle kicker from MOTEC that will jack the throttle open a bit to allow some air in.
My main concern though would be the extreme temparatures you would see with even moderate use so maybe a lot of attention to lagging and thermal wrapping / sheeting would be necessary and installation of an EGT guage would be highly recommended.
As regards water injection, presumably you mean for further protection by reducing inlet temps as most tuners see this as a safer method of use rather than a method to increase power with relevant boost / fuel mods. i.e. when the water runs out you could be in the sh!te !!! As far as water tank location maybe consider putting it in the cabin behind one of the seats - depending on your use of the car of course. It strikes me that it would be rather more convenient to fill and not be subject to heat soak there than in an awkward place under the rear clam.
Just a few thoughts of the top of my head

The Escort used to run out of water at about the same time as fuel, so simply re-fueling and watering at the same time. I looked into this a bit before I bought the M400. Original idea was to buy the cheapest secondhand 3R I could find, and then have the engine played with. Spoke to Engine Advantages, and Mountune. Both thought that 500BHP should be possible. Was thinking of flowing the heads, and re-mapping for about 1 Bar, with Optimax, and water to stop det, and poss bigger injectors also better intercooler, with water spray/fan. Even spoke to Quaife about a 6 speed sequential box. Anyway Noble went and brought out the M400, and stoped my plans in their tracks. My next plan is a very, very, powerfull and sequentialy boxed Ultima (just don't tell the wife).
