so the only thing you have to change from a stage 1 to a stage 2 is a smaller pulley, remap, charge cooler?

Correct.

[The Batman]

are they stocking the large pulley yet? very interested in this, leaves room for mods, for when im a good track driver!

I don't know if they are stocking any yet as they had mine made to order. It's quite difficult pulling the old pulley off so I let them do that.

[mandarinvx]

You could consider something like this if you plan to change pulley size

Nice work Muncher.

Does that mean that Courtenays have taken the Laminova cores out of the intake manifold prior to fitting? And that they'd need to be re-installed when/if you move to StageII (which presumably still needs the charge cooler and pre-rad)?

Why do you take the laminova cores out? what does this thing do?


Great work BTW!

It's the heat exchanger surfaces in the manifold which the chargecooler uses. They're taken out because they're not connected so only act as a restriction in the airflow which makes the supercharger work harder perhaps which would increase intake temps.

Ahaa allright! Why have you choosed to not have the water cooling to the manifold connected?

My stage 2 conversion also hesitates when giving very slight throttle travel at low revs. This mainly happens when the engine is cold, and goes away when warm. I thought it was just a characteristic of being SC'd.

As that's the point of the stage 1 kit, it's cheaper as you don't have the cost of the full chargecooler system and if you don't fit it yourself you don't have the labour costs of fitting it which isn't a quick job, both clams off etc

[The Batman]

how big is the pulley that you are using?

[Muncher]

I don't actually know, I haven't measured it.

[The Batman]

if you could measure it and take a picture it would be much appreciated

[NickB787]

Well done mate. I would imagine there will be a few takers of this.

[The Batman]

is there an update to this?

[Muncher]

is there an update to this?

Seems to be running fine and I'm booked in for final mapping at Courtenay next monday.

look forward to see some graph from john on this one well done on doing it yourself
i am looking on doing mine one day so will get a quote from john
his rolling road is very conservative but i am sure he will find xtra bhp well gain

[Muncher]

Yesterday I spent the day at Courtenays having my new Stage 1 supercharger install checked over and having the map tweaked.

Here are the results:



As you can see the graphs are so smooth and that is exactly how the car feels to drive, instant and progressive power. If it wasn't for the supercharger whine, (which I now quite like actually), you couldn't tell it was forced induction from the way it behaves. The power delivery is immensely preferable to the various turbos I have driven.

As a brief summary of what the Stage 1 consists of:

- GM Supercharger
- GM inlet manifold
- Inlet manifold gasket
- Inlet to supercharger gasket
- Air filter
- Silicone hose
- Throttle body adapter plate
- MAP sensor
- Injectors
- Injector plugs
- Injector Boots
- Idler pulley and bracket
- Longer belt
- Coolant hose extender
- Dipstick bracket
- MAP sensor retaining bracket
- Supercharger blanking plug
- Coolant
- Crank breather hose
- Crank breather T piece
- Inlet manifold locating collets
- ECU remap and rolling road time to test and tweak the map
- A whole load of cable, sheathing, various heatshrink, solder, bolts, hose clips and cable ties

The quoted power level is officially 210bhp and the price fully installed is £3,300 inc VAT

Whilst I fitted it myself I think that price is pretty damn good for a drive in, drive out warrantied install which gives something like 60+ bhp over standard, especially as it provides a great basis to go to a stage 2 at a later date with the installation of a charge cooler, a smaller pulley and laminova cores for a relatively small cost.

If you are interested in fitting it yourself then please call Courtenay and speak to Jon, however, bear this in mind before considering doing that:

- It is quite a fiddly install
- It's probably going to take most people at least a week to do it
- You will get scraped knuckles, a bad back and sore hamstrings
- You must be confident in messing around with wiring
- You must be quite methodical and organised, check and double checking everything
- You must have a reasonably good tool kit and an appropriate place to work
- The ECU needs to be sent off in the interim to have a suitable map applied
- You will need to return to Courtenay to have it properly mapped and checked when completed
- If the above doesn't sound like good fun to you, don't do it

So whilst it isn't beyond the realms of a DIY'er, it won't be suitable job to attempt for a lot of people, partly due to the length of time it would take. When you also include all the little bits and pieces you need to buy it all adds up.

All you need now is the 4.17 final drive to compliment all of that power.

MAXR "A 4.17 ratio box is a another great upgrade for any S/C VX. "

I could sell you a brand new one for a bargain price, PM me if interested.

So how much is just the kit??

I don't know exactly, in the region of £3,300 less 3 days worth of labour then plus a bit more to cover mapping time I guess.
