The whistling is coming from the pipe that goes from the inlet hose to the ISV I had to "manufacture" the connection and the hole is making the whistle. It was doing this before I fitted the charger, but was much quieter then.

ok VAG COM has no errors wondering if relocating the MAF upstream of the charger will help. http://www.the-corrado.net/.archive/forum/viewto ... l&start=15

I had the biggest smile on my face! I'm just charging up my tablet pc and then will run a quick vag-com on it in a bit to see if it throws up anything. I think bhp must be at least 270 - 280 now (it feels more though and i managed to spin the wheels in 3rd gear!) The current stealth remap will be limiting the output no doubt, but i will probably get the chains and the head gasket done before I take the C up to Vince again though).

Right then, right then!! All fitted and running now! All I can say is "bloody hell!" You wouldn't believe the difference between this and the z-eng charger. It sounds like a jet engine and goes like one as well. Haven't pushed it too hard yet, but makes 5psi boost pretty much as soon as you hit the accelerator. Absolutley wonderful! The dump valve works well with a satisfiying "pshhhhhtt" when you let off the accelerator. Turned every pedestrians head when I took it for a spin round the block, bet they were all thinking "what the f*ck is that!!" Only two niggles now: 1) the whistling noise is pretty load 2) when letting of the accelerator too sharply , it is stalling - any way to remedy this easily (ISV maybe or adjust the dashpot?)

can't remember which one i have got, i think its about 90mm (will have to verify) off the top of my head i think 8psi was mentioned with the standard pulley. quote from r-techs.dk (where i got the charger) "We have pulleysizes from 60 mm to 110 mm in 6,7 and 8 ribs. If you want a special mm-size we can make that also. PSI It depend on the pulleysize but 20 psi is possible" the bailey dump valve is a DV24 single piston (good for 60psi), never used one before though so not sure how well its going to work.

aha yes it is used to tension the belt. apparently the triangle wedge shape part is used to force the smooth idle pulley along the slot it is held in on the bracket by hammering the top of it. like a wedge to force it and thus tighten the belt, any other slack is taken up by the original idle tensioner that is now installed on the bracket. maybe that doesn't make sense! hard to explain without taking another pic. tomorrow i have a few things to do install oil system prime oil system install belt. tension belt install inlet hose and k&n filter put mapped chip back in (from my previous visit to stealth) start testing it! I will take more pics as i do these and post over the weekend.

Just thought i'd grab a pic of the latest progress. I sorted the intake hose and fitted it in the dark to try it for size, works pretty well! Black hose is from a Renault 5 Turbo (as it was the right ID and had all the right bends in it) Also note the Bailey dump valve (recommended by rotrex).

I have filed about 3mm of the head, seems to be enough clearance. Boy is it tight though! The smooth idler puley clears the fuel rail by about 2mm and the C's own idler pulley clears the fuel inlet and outlet by about the same distance. (this seems to be the tolerence all round in fact). The mounting itslelf is very solid. Only headache now is to route the inlet hose and filter. I had already moved the carbon canister, so I am going to move the k&n into the hole it left behind and run some hose up to the charger. Thanks for all your help and support Kev (this goes for everyone on the forum as you are all a great bunch) More pics tomorrow!!

Right then, I got hold of the guy in Denmark and aparently I do need to grind a few mm of the manifold. There is a small area of metal that sticks out that can be cut away (but only about 7-8mm) on the head side where the manifold meets it (where the gasket is). My only concern is that if i fuck it up then its new head time.

Hey Guys Does anyone know the 3 GSF part numbers for the 2 oil pressure switches and the oil temp sender? They seem to list quite a few options Cheers

Thanks for the vote of confidence Kev. As they say... rome wasn't built in a day.

right then, some updates. I think i have solved my alignment problems.

thats what i was thinking.. the hole would suggest its used a pivot point for leverage perhaps? still can't email the danish guy though... might try from a different email address to check its not just my email account.

I also forgot to mention this... What the hell is this for?? Its about 25cm long and about 8mm think. The hole in the end isn't threaded and is about 7mm in diameter.

@ mr_fusion hey can i ask where are you getting the z-engineering charger rebuilt ? i have only been able to find mc racing autorised dist for z chargers and rebuilds i have e mailed them for details about getting mine done but no reply at all i want to get it upgraded to a stg 2 and a new tensioner pulley. they say on their website that it has to be paid for in full by bank transfer but dont seem to reply to emails. i have emailed numerous times :x VR6boy - PM sent

I might actually try and mount the bracket minus the supercharger this evening to see what my clearance options are. (damn sight lighter with out the charger as it may be small, but it weighs the same as the Z-eng)

Here is a pic showing the belt wrap. (it may become more obvious as this is the position the bracket would be mounted in) I does not show the idle tensioner in this pic though as i took it off to try and fix it after my "accident"

Yes, I am definately mounting it correctly (it becomes obvious when you see it in place) the picture should be rotated about 80 degrees CCW and that is how it fits. The idler bolts to where you can see the three M8 bolts in the pic. The idler pulley mount on the shaft with the allen head on it and can still be adjusted as if i was on the car. The bracket attaches to the engine via the other three points (at the bottom of the pic) there are 2 spacers welded to the bracket and the small stud that bolts into the head and allows you to hang the bracket of the engine while you put in the other 2 m8 bolts to secure it.

I spoke to soon as my email has just been returned! Arse

I just resent my email to him (also enquiring about whether the bracket is correct) and it hasn't bounced back yet.. so fingers crossed!

Thats just the idle tensioner (the part that usually bolts to the engine) if thats what you mean?

the pic from storm developments clearly shows a 12v engine so it should fit somehow

In all seriousness, is this a probabilty (regarding the bracket being for a 24v)? I'm sure I can get a different bracket if this is the case. It will just be a major pain in the arse. The z-eng charger is all fixed now, so that wil be up for sale soon.

Thanks Kev, I will take a look again later then. I can't get through to the guy in denmark at the moment as my email is being bounced (user quota exceeded), but I will persevere.

Kev, is it safe to remove a small amount of material from the end of the manifold (where it meets the head) as long as it doesn't cut into the gasket? I need about 6-7mm.
