now many things to resolve good luck ^^

oil return for the top cover
ecu
link to the accelerator
air box
water tank

also do you think the big pipe from the radiator don't allow enought clearance for an air box?
is it possible to ahve trumpet in circle shape ? so they will look up ^^

that nice you investe in developing this solution
 
Soooo jealous right now :/ how long before at power start to release this to us ?? Or is it just dependent on how you get on with them Neil ??
 
Just woder... the injector will be not better before the buterfly? like F1 car ...

Looking good bud, does your cams suffer from charge robbing on the standard inlet or is it like the clios and the inlet ain't the greatest?
Charge robbing or reversion. Either way, theres a significant fluctuation in inlet manifold pressure at 3K and large throttle demands.

You missed the two vacuum hoses and fuel rail plumbing. Also, studs/nuts for mounting them onto the head

Water tank and radiator top hose should be out of the way tomorrow

Pass. Ask Wayne, sales manager of AT-Power ;)

Theres a huge difference in the operating RPM beween my car and an F1 motor :?
With the injector placement where it is, fuel will spray onto the back of the hot valves which should allow it to atomise well at low RPM and small throttle opening. If the injectors were only at the bell mouth, small throttle openings will have low air speed and also have the throttle plate in the way of the fuel/air mix which can cause the fuel to drop out.

A second set of injectors, staged so they start to work at higher RPM and throttle opening will help increase the mid range and top end power. With further distance to travel, the fuel atomising will cool the inlet charge and have time for a good mix without meeting a closed throttle plate
 
i so cannot wait to hear her scream when this is installed it will be pure car porn :Q___
 
hmmm shit

you will loose the assistance on break ...
in this french forum they say they manage but I can't see how it's plug

maybe need some machining in the throttle


going for 4 throttle is realy complicating in fact ^^


édit : I see some hole next to the hole of the injector on your picture
is these hole are for piping some stuff like brake?
 
the more I read thread about ITB the more I think it need 2 "layer" of injector to get the best of it ^^

also apparently it can be in fact even more easy to map
cause you can put small injector for low rev that guive a nice low rev mix (air/gaz) and big injector for high rev and full power (big injector are bad for low rev)

I think ECU like sybelle challenger 5 andle this kind of setting

the bad point it's since MAXI rally car nor more exist almost no car run on this kind of setting
So hard to find part to adapt such system

Wayne confirmed my thoughts about these being intended for vacuum take off :cool:

Curently blind tapped but they can be drilled through if required. Another option is using an Audi A6 vacuum pump ;)
 
Great

just use this hole seem's fine (apparently the best is to link them )

there is also the pressure probe, I guess you can plug on it

the temp probe on the air box and that it !
but apparently these kind of ITB need also a lambda sensor to make easier mapping (cause pressure will be not so reliable in this setup, also you can get ride of the air box if using mapping from lambda)

after I'm not professional but sounds fair

édit : Also forgot the other pipe that came to the inlet that I don't know for what it is ^^
 
Holy F*ck Batman...

They look awesome Neil! can't wait to see/hear them in action!
 
Omg these are going to be amazing I can't wait for them to be done! And then I want them for my baby :l
 
I guess that was you following me earlier before heading up into town. Looking its muckiest at the moment. Really in need of a wash as I couldn't work out if it was Harry or yourself following
 
Yeah, was just heading into town and had to follow for a look! Can't say mines the cleanest either with the weather!
 
A couple of minor changes recently :)

The VW coolant tank was mounted last month. But, it was only yesterday when I got around to connecting it up and wrestling the original tank free.






Created today by Nick of Custom Craft in Elgin. I think this suits the rear much better than the single round tip.






And, after registering and paying for access to Infotech, I've now got the wiring diagrams for the ECU connections :cool:
