just2zang 0 Posted May 21, 2004 Report Share Posted May 21, 2004 Well I got it installed but I am suffering from a few problems. The piping supplied was not right for my car. I have one pipe from the charger to the mass air sensor. Then used the standard piping to the throttle body.The one way valve (black bosch plastic thing) has not been installed (and i dont know where to put it). ?! The car has no chip installed. It stalls on startup unless throttle is pressed. It only started to do this after driving it around for most of the day. Erratic idling starts higher and slowly settles, but seems to be settling at higher rpm, the more i drive it. %-6. I am only reving to 5k max. Car is also hesitating and holding back. The charger itself has been fitted very well, no belt slip, etc..Any ideas guys, and will definately get the rounds in at the next show [ Edited ] Link to post Share on other sites

There is a rubber pipe - about 1cm thickness, coming off the throttle body at the pulley side, this is where you put the valve. Cut into the pipe and insert the valve. Ensure the engine can suck through it, but not blow through it, otherwise you'll be inflating your fuel tank. You must fit this valve.....3) Dont run it over 4k with no chip - your engine will die.Jules Link to post Share on other sites
jcorallo 0 Posted May 21, 2004 Report Share Posted May 21, 2004 ...also - I'd be surprised if the standard piping could withstand being pumped up to 0.6bar....! Link to post Share on other sites
mightyvr6 0 Posted May 21, 2004 Report Share Posted May 21, 2004 The blue samco 90 degree elbow (with the small pipe attached in your pics) is the throttlebody-maf pipe but the small hose has to be blocked off with something like a bolt and jubilee clip on obd2. Link to post Share on other sites

eViL 0 Posted May 21, 2004 Report Share Posted May 21, 2004 Jules - I know we're going over old ground.. but wouldn't an atmospheric dump valve solve the MAF problems on OBD1? Link to post Share on other sites
jcorallo 0 Posted May 21, 2004 Report Share Posted May 21, 2004 thread hijack - thread hijack!!tell me why you think this...... what is your thinking behind this?Jules Link to post Share on other sites
eViL 0 Posted May 21, 2004 Report Share Posted May 21, 2004 Simple really.. the left over boost is injected into the air rather than being recirculated back into the path of the MAF.I've also been thinking about inserting some tubing into the actual intake pipe to direct the recirculated air AWAY from the MAF.. but I'm just far too dumb to pull it off.[ Edited Fri May 21 2004, 06:04PM ] Link to post Share on other sites
mightyvr6 0 Posted May 21, 2004 Report Share Posted May 21, 2004 The point of the recirculating dump valve is to prevent air from the impeller spiralling back down the intake onto the maf. An atmospheric dv wouldn't stop this happening. The return pipe from the dv points towards the impeller to prevent recirculated air and air from the impeller reaching the maf. The maf should be far enough away from the intake so recirculated air doesn't interfere with the maf's readings. Link to post Share on other sites
eViL 0 Posted May 21, 2004 Report Share Posted May 21, 2004 The intake isn't doing this though.. hence the reason VF-engineering released an updated version. For £100 I could get the new intake, but I don't see why I should when I paid £2500 for the system in the first place! Link to post Share on other sites
eViL 0 Posted May 21, 2004 Report Share Posted May 21, 2004 I ran the car for a short time without the flexihose and it was SO MUCH quicker. But when the ECU tried to keep up with the air going in all directions, eventually the car wouldn't run at all. Link to post Share on other sites
eViL 0 Posted May 21, 2004 Report Share Posted May 21, 2004 Why wouldn't the Atmospheric Dump valve stop this from happening?Told you I was a dumb-ass.. Link to post Share on other sites
mightyvr6 0 Posted May 21, 2004 Report Share Posted May 21, 2004 The flexihose is to extend the maf away from the supercharger intake. You can bend the flexi hose 90 degrees (if there is room) so the maf sits horizontally or extend it vertically to take it out of any air turbulence created by the dv/impeller. Without the flexihose it must have been running super rich so the ecu was registering more air and putting more fuel in giving better throttle response etc.I've never seen a maf before the charger with an atmospheric dv, only with the maf after the charger. Jules would know whether it is possible or not to run this setup. Link to post Share on other sites
just2zang 0 Posted May 21, 2004 Author Report Share Posted May 21, 2004 click here to see the piping, its better than me trying to explain The kit was originally made for obd1. Mine is obd2 and the piping isnt long enough, it was custom fabricated for the car it was originally made for, and the finish wasn't perfect.i have heard that the recirculating dumpvalve makes no difference on obd2 as its essentially recirculating it in the same place and your only running low amounts of boost. Opinions?has anyone got any pictures of their piping on an obd2? I've been told to try and get the correct piping off nik saran when i see him next week.My car has a is showing a faulty lamda sensor in the diagnostic. So its either the wiring to the sensor, the sensor itself or the cat playing up.. It is causing poor running. Anyone know where the cheapest place to get a lamda from?Please allow for my ignorance, im am neither a mechanic or supercharger specialist, and this is my 1st supercharger. :?

mightyvr6 0 Posted May 21, 2004 Report Share Posted May 21, 2004 Will the hose you've got on your charger intake fit between the throttlebody and maf? Then you can fit the hose with the dump valve on the end on the charger intake.You can't have a recirculating dv with the maf after the charger but you can have an atmospheric dv positioned between the maf and the charger. The recirc. dv on obd1 cars was to sort out running issues associated with the maf and is not necessary on obd2 as the maf is less sensitive. A dv is a good thing though as it stops air from travelling against the flow of the charger so it boosts sooner when you get back on the throttle. Link to post Share on other sites

mightyvr6 0 Posted May 21, 2004 Report Share Posted May 21, 2004 Samcos can be bought from some where like demon tweeks. All you need is an 80mm 90 degree bend, which they stock, trimmed to the correct length to fit between your maf and throttle body.Your car *should* run ok with the maf after the charger but it's best to run the maf before the charger as you'll run rich off throttle. I'm not experienced with obd2 but this is true for obd1. I do know that Obd1 cars run like crap with the maf after the charger.Doesn't Reuben have obd2 supercharged-where does he run the maf?

just2zang 0 Posted May 21, 2004 Author Report Share Posted May 21, 2004 reuben had a charged vr but sold it 6 weeks ago. He says my charger is different from his. It looks like a vortech charger, but is not one he has seen. He belies the maf is fine or will be fine when the correct pipe is purchased. do u mean i can run the maf just after the cone air filter? if so, how far from the charger inlet?

jcorallo 0 Posted May 21, 2004 Report Share Posted May 21, 2004 This is totally wrong as far as I can see,This intake pipe now contains boost - and you have left the crankcase breather pipe connected to this.So what you have here is some of the boost going into the engine crankcase, instead of the manifold.Do no run your car like this - get the proper pipe..Jules Link to post Share on other sites
jcorallo 0 Posted May 21, 2004 Report Share Posted May 21, 2004 Looking at this picture, the pipe thats in the middle to the right, is the one that connects the MAF to the throttle body.It looks like its the right length - as you can see, one side of it is a bit longer than the other. For reference, it actually fits in the engine bay the other way round as shown in the pic above.Jules Link to post Share on other sites
mightyvr6 0 Posted May 21, 2004 Report Share Posted May 21, 2004 Yes, like Jules says, you'll be pressurizing the crankcase by leaving the original pipe in place. I'd buy a new 90 degree samco for the maf-throttle body and get the crankcase breather plumbed into the intake if the pipe with the dv in it doesn't fit anywhere.[ Edited Fri May 21 2004, 11:14PM ] Link to post Share on other sites
simey 0 Posted May 21, 2004 Report Share Posted May 21, 2004 This is totally wrong as far as I can see.If I'm seeing right, the oil breather pipe is going into the air intake pipe? If yes this is totally crazy as it will F##k the maf senor and the throttle body.P.S. I wouldn't run the car as it is. Link to post Share on other sites
eViL 0 Posted May 22, 2004 Report Share Posted May 22, 2004 I'm pretty sure your Maf needs to be between the charger and the filter mate. Whilst you still need the chip for it to run properly, I know for a fact OBD2 cars do not need the flexihose.The OBD2 Air Flow sensor handles the recirculated boost just fine.[ Edited Sat May 22 2004, 11:20PM ] Link to post Share on other sites
eViL 0 Posted May 22, 2004 Report Share Posted May 22, 2004 Your charger really needs to be looking like this..as I said before.. the MAF should then travel from the charger intake with the filter on the end of it. It would sit right infront of your wheel arch. Link to post Share on other sites
