Apologies Carolynne, I understood it to not be running correctly for regular use therefore being unfinished. If it runs ok as is that's great.

I was looking at your photos again and wondered, do you think if the SC was flipped 180deg with outlet downward would a 2zz manifold fit above it? And run charge pipe under the sump? Just thinking aloud.

Thanks

Edit: ah is the subframe in the way? Not too clear in the later pics.

The supercharger will be in the way of the manifold either way.  Custom manifold required.  You're guessing.



Edit: nope looks like it'll clear the subframe. You might have just solved my problem Carolynne. Thanks

Hi Carolynne
Which part is guessing? I realise the manifold is in the way, that is clear in your photos.

I apologise, I'll take my ramblings to my own thread and get back to work on it.

As there is renewed interest in this, I'm bumping the thread, so you all can fond it.

Right some of us have been wondering... the idea behind what comes next is to enable this modification to be used by more people be enabling the use of any mr2 mk3 manifold, stock or aftermarket.

Is it possible that a "spacer " could be created that would have the same holes as the manifold/head and essentially be 4 tubes held together at each end with the equivalent Mounting brackets?

That way you don't have to spend more money on a custom manifold, just the cat to enable it to go to the standard exhaust mounting point?

So yeah 4 tubes of appropriate length, held together on each end with the mounting plate that is on the end of the normal exhaust manifold that bolts to the head. You attach it to your normal manifold via a standard gasket and some nuts and bolts and the same again to connect the whole thing to the engine block.

That then means you just need a cat pipe to go to the exhaust via a s different route, 2zz injectors, and the silicone piping and a piggy back?

You mean like the exhaust manifold we actually built?  We  cut the flange off a Toyoysport, welded in four extension tubes (long enough for the rest of the manifold to sit to the rear of the subframe). Then we built a 2 1/2" cat pipe to go to a smaller flat silencer. so it would all fit in the available space.

Piggy back won't do the job, I'm afraid.  Has to be stand-alone ecu and a couple of hours on the dyno.

The piping is more complicated than just 'silicone' (especially the input to the supercharger)... but essentially that's what we built.

Then there is the matter of making the correct sized multi-grooved pulley and broaching a key-way for it  into the drive-shaft on the supercharger.  Plus designing and fabricating the mounts to bolt the supercharger to the engine....

Fair enough, the idea behind the manifold "spacer" which would be a bolt in affair, was that it was one less item of custom welding that people would have to take to a shop. 

In the grand scheme, I was thinking that if people wanted to do what you have done, they could source their own charger and ecu etc but could purchase the custom fabricated stuff like the manifold spacer, the pulley and the charger bracket from you. 

I'm basically theorising how to make a kit that's all 😃

Fair enough.  I'm afraid there's zero chance of our producing kits, though, John!

Anyone who wants to copy what we've made is welcome so to do.

Do you have an idea of the bhp with this supercharger ?

I don't 'know' for certain.. We're using a fairly big pulley and keeping boost down ,so I'd guess at around 190.  One day we'll have it dyno'd and then we'll know!!

Stop press.  Progress is now being made on tuning the thing, thanks to Jonbill.

On the emanage?

Speeduino.  Emanage can't do it.

It's Jon's project.  He has the car at his place.

Excellent! Open source  

Looked at those a while back and they showed great promise to be what MegaSquirt used to be.

Also, when done, it really opens up possibilities for other forum cars.

So basically you've outsourced us hassling you about this project to @jonbill nice

its early days, but it was making some decent power at low rpm yesterday evening (until the inlet duct resonator blew off)

Nice work glad to see its moving along , although in some way i was hoping you would loose interest and split the kit of it and i could buy it for my car

Would it be beneficial if you were provided with an aem kit (the pipe plus filter (old but still serviceable)

maybe, but I think the immediate problem was that the BOV wasn't set right, so too much pressure on closed throttle. I might come back to you, thanks John.

This is the kit just as a ref, the pipe is so long you'd probably end up with it working all the way back to the side inlet!

Happy to donate my Hurricane to the cause

Thanks for the offers, guys, but:

Don't forget there's custom pipe work from the outlet of the supercharger.

The present inlet tract works quite well. We'd have to re-do a lot of the plumbing if it were changed.  Plus the accordion rubber tube makes a good shock absorber.

@jonbill it'd been long enough now! What's been happening? please tell us something...

Jon was making good progress when.... one of  the gear cables died.

He's now replaced the cable (HEROIC!!) and has now decided that we need to fit the smaller pulley (which we had made in case it was needed).

We are now awaiting a new auxiliary belt as it needs to be shorter for the smaller pulley.

So far, he's reporting useful power increase lower down, but not much higher up.  He got the thing to run sweetly and to rev out, so it's not far from being a winner!
