;D Well did some thinking and some looking, and some "That looks about right There"ing ;D Starting point: K-jet MAF bottom left corner, throttle body at rear of manifold. PAS Pump smack bang where I want to put the charger Radiator Middle RHS, intercooler will sit in front Charger roughly right position in X & Y, will Drop in Z when the PAS Pump is moved Inlet is at rear of charger,air will come from MAF, around the rear of Head, lower than currently sited. I just have to change the breather system into a catch tank and single pipe to intake, from the current spiders web of curse word. The Charger outlet is "underneath". I have the Outlet Casting as well, which willl get cut and shut to match single pipe. It will disappear into the Rad Ducting where the intercooler will be sited, then back out and round the back of the motor to the TB..... The plan is to move the PAS pump, lose the injector cooler fan and shroud and get it all running in its new location, then mounting the Charger and Pipework and hooking it all up. So Breather system first FEAD Belt system second Charger Mounting Intercooler Pipework Fuelling Job done ;D As always, all suggestions/links/etc Gratefully recieved Cheers Dom

i have no idea what you just said, but looks bloody cool LMAO ;D Just spat me tea all over the place ya git ;D Just think of it as a Big Air pump with another little air pump bolted to the side ;D The rest of the Techy stuff is just joining the dots so to speak EDIT Sorry Adam its from a Mini Cooper S, Eaton M45 Got it off Fleabay with the outlet casting and waterpump mounted on the back as well normally they are just bare

Yep I have thought of that, there is an electric powersteering pump system available, it is used on some Paxos I think. I am currently planning tomove the existing pump ( 1st pic front centre) to under the manifold in the 1st pic. Abbreviations, sorry force of habit MAF: mass air flow meter (1st pic left middle with all the pipes coming from it also called a metering unit, measures airflow through it and controlls fuel flow accordingly. TB: throttle Body....bit with the cable going to it, think of it as a twin choke Carb without fuel PAS: power assisted steering FEAD: Front End Accessory Drive - belt system to alternator, PAS pump, air-con compressor, supercharger etc. Can also be run from the back of the Camshaft, as on new straight six Volvos then Called a READ Hope that helps ;D Cheers Dom

you know on the right where the rad sits its set back with a space in front
interecooler in front part of space with charger in middle between rad and cooler???
no??

How are you gonna recalibrate the fuel injection?

How are you gonna recalibrate the fuel injection? Audi 200T metering unit and or Injectors, may only need to use the standard cold start enrichment injector, as they used to do on RS-Turbos when they upped the boost. Not sure how they did that but it probably isnt that hard Not 100% sure which way to go yet. Need to do some more research, had some good ideas from the Audi S2 Forum so far, Its down to me to get reading up on tuning the K-Jet I`d like to go standalone with Megasquirt or Emerald but 1 step at a time.... It also has to be totally reliable as I don't want problems stuck in the Alps somewhere All suggestions gratefully recieved as always Cheers Dom

Interesting idea! What Audi is it? As for K-jet, I now know more than I'd like to about it from extended reading and fiddling to sort a cold starting issue on my Golf 16v. Do you have a fuel pressure gauge? If you are planning to alter system pressure and/or control pressure then it's well worth getting hold of one, it's basically a lottery without if you're trying to adjust it and don't know how your adjustments are affecting the pressures. I have some good k-jet links somewhere, will dig them out.

Surely you’re going from a situation where there is always a vacuum in the manifold, to one where theres both vacuum and positive pressure. SO how will you measure that and supply the right amount of juice? Surely the system (i.e. brain, and manifold pressure sensor) wont be equipped to deal with this sort of situation. Obv there are ways to get around it, I just don’t know what they are…!

Does the Audi warm up regulator (WUR) have a vacuum take off on it like later model VW ones do for full throttle/cold enrichment? Presumably you would need to modify this to take account of vacuum changes and alter control pressure (and therefore mixture) accordingly? Thinking about it, I'm pretty sure all supercharged VW's used Bosch Digifant electronic fuel inj as opposed to the k-jet mechanical setup. Sure it can be done with k-jet though! It's worth bearing in mind that fuel delivery in k-jet is controlled only by the air flow in the metering unit rather than vacuum pressure at the manifold as in other setups so don't see why it wouldn't be possible with some re-calibration/fettling.

Thanks Stu, I`ll get reading Its a 90 Quattro Thats my understanding of it too, the K-Jet is a Mechanical FI system, not electronic. the metering unit determines how much fuel is supplied depending on how much airflow it sees through the Flap. TBH I had not thought of it untill someone posted up pics of that Turboed 6.9L Merc, and all he had done hardware wise was plumb in a Turbo between the Metering unit and the Throttle Body. That got me thinking..... Providing all the airflow comes through the metering unit, I think its a question of fettling more than anything else ? The Turboed Audi Quattro used a K-jet so it can be done with forced induction, although I am not looking at anywhere near the kind of figures some of the Yanks are running on the same system: 100/200 turbos are easy enough to find cheap now, also had a sugestion of using a Metering unit from a 450 merc V8..... As K-jet is non sequential apparently I can just use 5 of the 8 ports ;D The mercs and turbos use bigger injectors as well, I am sure between standard and larger injectors, standard and higher flow metering units and fuel pressure changes, I can get somewhere pretty close to where I need to be ? We will see I`ll check the WUR and let you know Cheers Dom

Sounds good, keep us updated on progress. I found the pdf manual on K-jet on my work PC, can email it to you if you like - very good explanations and diagrams of how it all works in there. PM me your email address if you want it

You may want to nick the kjet from a saab 900 turbo8 as the fueling is pretty high flow - I know, I pay the fuel bill!- and while you are there, take the complete APC boost management system, it's relatively simple to install and massively tweakable. It's been retro fitted to many different forced induction engines. Take alook at this site for example: www.geocities.com/MotorCity/Garage/6776/apc.html

Take alook at this site for example: www.geocities.com/MotorCity/Garage/6776/apc.html Hi Ken, Thanks for that Have you got any more links explaining how the APC system works ? The difficulty with running the Saab metering unit is its one injector short The Audi is a 2.3 5-pot ;D But will take a look for injectors and stuff cheers Interested in knowing about the APC thing ;D Cheers Dom

I have been looking for this too, but I am struggling. ANy news? I only want a simpleish explanation of how the system works.
