Yep, I wouldn't say it was a waste of time (maybe money) but I had fun building it, I work on cars every day but still enjoy getting stuck into mine. Now I can say been there done that, N/A is where it'll stay now, as previously said, I already have a mad intake design ready to go.

Yep my thoughts, it did go bloody well, who knew it was only running on air at high rpm.

Wasn't prepared to put more money into making this kind of charger work, if it was a 400bhp performance one then yeah sure it'll be worth it. No big deal, custom plenum works well without it.Had to give it try ha.

I like the shape, something different, different as in not a roof chopped bettle as all 911s are.

Well as quick as it went on it's now come off, had the dyno/co2 test today. Bad news, with the charger switched off the fuel map is bang on, with it switched on the co2 goes to 6% at idle, 9% at cruise and 12% at full throttle but then suddenly drops to 0%, fuel can't keep up with air delivery unfortunately Not a happy camper but at least the engine is now safe, have connected air flow meter straight to the intake pipe of the plenum, seems to go really well, better than factory anyway. Edit: I don't give up however, already have plans on different intake systems

He is one switched on guy, wasn't planning on watching the whole thing but then half an hour later it finished haha.

Yeah I fully understand that and I appreciate any advice you can give me Steve. Actually relying on it haha.If it all gets to complicating and looking like more money will need throwing at it i'll remove the lot and just go back to N/A whilst playing with different intakes, CSL for instance.

Seems to smell lean when idling with the charger on. Not running the best at idle due to the way the valve is operating.From what i've been told the engine is over driving the charger thus why the valve is pouring out boost at idle, so yeah a larger crank pully is requiered.

Ok will try that, haven't touched the adjustment on it yet as I assumed it was setup when Garett had it. Also it appears I may be able to remove and block the vacum hose on the fuel regulator, puts it from 2.5 bar to 3 bar.

Used to be a nice car, someone should tell him his front cam covers have come off.

I wonder when this one was done? Doesn't have the J gate?

Talked to a forced induction/cosworth guru in town today, gonna have a co2 test tomorrow, I think the reason for the bogging down is when the blower is switched on and the engine is idling it's putting a few pounds of air out the bov, for some odd reason the bov is open at idle, touch the go pedal and it quickly shuts, I thought if I plumbed the bov back into the air intake before the blower that would help it???

The idle valve hose goes straight into the plenum, seems fairly happy how it is.

It certainly made very well, gives it an awsome noise the old alloy.

Just the air flow meter as i haven't made up the proper intake system yet. Running an on off button for now.

Ok, i'll try that tomorrow at work.

Didn't realise you could blow through them, unfortunately there is no room for the maf to go after the charger as it just has one 90 degree elbow going from the charger to the plenum otherwise i'd be in the shed doing it now.

Before the charger.

Yes he is.

The crank is def smaller than the blower pully but not by much.Also it's not too fond of taking off normally from intersections etc, it bogs down then goes, I suspect it may be running a wee bit lean, will find out soon enough. Ha Micheal, i'll have my fun then we'll see what happens.

I don't have a boost gauge connected at current so unsure. The approx sizes are 110mm for the crank, maybe slightly larger as I just measured while on the car and the blower is around 120mm.

Hastings NZ, I have been to the workshop several times, they do a good job, shame about the management of the place though, very poor people skills, I could say more about one in particular but won't.

Repco and supercheap sell them.

This is pretty much a finished project but will post it up anyway. This is a bit of a read and picture heavy. The pictures were taken off my phone so some are sh*t, I apolagise. Ok, where do I start, it was thursday night, Mark, Brett and i were at the pub (thirsty thursday etc), came home half liquered up, decided to have a gander at Bimmersport and happened to see a For Sale thread that came of interest to my liquered self. Next thing I know i've purchaced it. Yes, pretty obviuos what it is. Excited to have it arrive at work, I took it home and low and behold, it doesn't fit....bugger. What to do I thought to myself, I know i'll take the exsisting plenum off (this is what was too big) and mount the charger with some heavily modified brackets (original ones didn't quite work). Few days later it was mounted. Please take no notice to the very rough looking brackets, they no longer look like that. As previously stated, it was evident a new plenum was needed, after visting numerous places and had plenty of estimates for making one (lots of $$$) I remebered that our master tech at work was an excellent aluminium fabricator that has made two very large aluminium boats (large as in 5-6 meter vessels) so the begging began. Needless to say he came to the party, I paid him of course, a lot cheaper than the other companies and this one would probably be flasher than the others. Anyway the work began starting with six flanges that bolted to the throttle bodies. Quite amazed that all he did was look and take a few measurements and they line up perfectly with the outer shape of the throttle. Next I bought six silicone hoses to go on the throttles. Next, the front wall of the plenum was made, again just from a few measurements of the engine bay and throttle position etc. Before the rest could be tacked together we had to come up with some runners, we kept with the same size as the factory ones. The rest of the plenum was then tacked together. A friend of mine who owns an exhaust shop flared the runners, aluminium can only be flared so much before it cracks so these weren't excessive but they do the job. We test fitted it then it was all welded up. And the finished plenum The kink in it was made to flow with the strut bar So that was the main bit done, this gives you an idea of what the intake will look like, the tubing here is far to small for my liking so will be using 3" tubing. Since this engine originally was N/A I had to remove the PCV valve and route the sump breather and rocker cover breather to a catch can. Then basically just tidying up all the loose ends. I t'd in the bov vacum hose into the booster system as this was pretty much the only place I could. There were a few other bits and pieces that were needed to be done then just making it all pretty. The finished project, well nearly anyway: The maiden voyage was yesterday, not a lot of difference down low but get to around 3 grand it it pulls right to 7 and a half grand, makes a hell of a racket with the aluminium plenum and runners, awsome noise from the charger, I believe the bov is stuffed though as it makes a terrible rattle/vibrationy noise rather than a ppssshhh noise, perhaps Steve would know? It had its pre supercharger dyno a few months ago so it will go back this week for the after dyno, wouldn't know how much more it will be producing. There are a few other minor issues I need sorting but overall pretty happy with it. Any questions feel free. Chur.

Happy birthing day dude, go hard.
