The ebay one is sub-ideal btw.

On the Rotrex there is quíte a bit on Spyderchat btw.

The eBay item isn't suitable for the zzw30 chassis but has all the parts needed at very reduced cost subject to final bidding, that was my point. Would need a mounting solution for which I could consider the AC location if I were inclined to try using a Rotrex, but as I said for less money and daily driveability (low-mid range torque) I'd prefer the Roots/Eaton SC and I have an M45 waiting patiently...

This can make a véry compact, light and silent install but the things are stúnningly expensive 

Do you have other pics of this setup

Hi all, sorry to revive an old thread, just wanted to say this supercharger kit lives on.

I bought it off Matt Lee Feb 2023, it has spent the last year sitting on a shelf in my garage and I've now started fitting it.

I came across this thread last night after some googling on maf positions and soon realised hang on a minute, this is where everything I have was born and subsequently read the whole thing start to end.
The supercharger itself requires refurbing, but I have another on the way.

So far the last few weekends have been spent making a complete custom exhaust, originally I was going to mate it to the original backbox flange position just to keep the cost down on materials, but ultimately that would have been a comprimise on what I wanted and also wanted to quieten down the exhaust I had a bit.

A couple of questions I have though, if those responsible can remember (apologies I can't remember names);

The maf tube mentioned in the thread is the oem one, the one I have appears to be a generic ebay item and of smaller diameter. When tuning, was there a reason the maf tube was changed or is it a case of a previous owner has decided to change for reasons unknown?

Also, regarding a bypass valve and the bov, everything I've read says maf before charger bypass valve needed between outlet and inlet downstrean of maf, however I have no bypass valve, but do have the 50mm bov also mentioned, the bov just vents to atmosphere. Is this the way it was when it was finished and tuned?

@MidshipMatt that bought the superblue kit from a chap called Matt.

What are the chances of that?

Have not gone back and re-read the 36 pages, but I know @Carolyn had the self assembled zorst side sorted when the kit was one the car she built.

No idea if you have the every nut n bolt. But if you have read it all, you will know as much anyone wise bar Carolyn. (and or Jonbill)

In terms of first opening posts, that has to be up there in terms of randomness. In a good way.
Hopefully the spirit of superblue lives on.

@Ardent yeah I have the complete setup, making a complete exhaust was just something I wanted to do, personal preference sort of thing and what better excuse than to finally start bolting everything up for the supercharger and make it fit round that too.

It was from reading the whole thread and looking at what I have that made me question have a couple of things been changed from what @Carolyn and @jonbill put together and tuned for, such as the oem maf tube and airbox, but the parts in the box I have are a generic maf tube of a smaller diameter than oem and a cone filter. Similar case with the bov, I have the 50mm bov jonbill mentioned swapping to, but no parts or provision in the inlet and outlet for a bypass valve.

Just little bits but bits that can make all the difference.

I'm hoping they see this and can remember what was done. I don't want to go changing anything on that side of things after reading the difficulties in it all coming together in the first place.

So true

I'm not happy about what happened to that car, so I am very reluctant to get involved all over again. 

When it left us it had the OEM airbox (inverted and rotated through 90 degrees)and MAF. As I recall the Speeduino ECU did not use the maf, it used an inlet air temp sensor, a manifold pressure sensor and a  broadband O2 sensor.

The exhaust took some working out and it was what was required to accommodate the supercharger.

There was no bypass valve. Just the 50mm BOV, which worked fine.  We left the MAF in place as it filled the hole and gave us a home for the MAF wiring.

You did not, it seems get the whole kit, which comes as no surprise.

I'm afraid that's as far as I'm prepared to go with any assistance, but I wish you well with the project.

Hi Carolyn, thank you for taking the time to reply and answer my queries.
I will have another dig through the box of bits I was given but it seems as though I'm missing a bit more than I initially thought.
I don't know any history about the original car etc.
I saw the "complete bolt-on supercharger kit" for sale 12 months ago, thought that sounds great and now I've got the time I'm just trying to piece the box of bits together, which is how I ended up coming across this thread.

@MidshipMatt will you do a build thread of your SC journey? I'd be interested in following and working things out with you. Interested to see your exhaust solutions also. Thanks
