Collected the exhaust manifold gaskets and nuts. Coolant. Intake manifold and water manifold seals. 2ndary air intake gasket and some other bits today.
I now have everything needed to complete the install.
However
I first want to clean absolutely everything. Every bolt and nut will go through prepsol. All the mating surfaces will be scraped and cleaned to scalpel level.
Then all the covers. All the internals as well. Coolant flush and oil flush will follow once its all assembled.
Before assembly starts ill also remove the current supercharger setup and install and align the ESS kit.
Seeing as there's space now to make sure everything aligns properly I want to make it work 100% from the get go.
Im not going to rush anything (even though the urge is there)
I also want to install a wideband O2 sensor in the xorst (which i still need unless i can use the secondary ones?) I have a digital AFR gauge already. Also have a Intake temp sensor post charger and post water meth on the intake manifold. Both to be wired into the cabin still.
Then changing pulleys and belts until the correct boost is achieved. And then finally proper mapping.

To make achieving boost easier. Check vortechs site, they have a pulley calculator that will make it easier. Just account for the 2 psi loss in altitude as well.Andy1GP@TheFanatics said:Collected the exhaust manifold gaskets and nuts. Coolant.

3 psi loss at altitude. I've done enough calculations and testing.
Running the VF kit with their 9psi setup (Correct size pulley and Belt from VF) I was only getting 5-6psi in JHB.
http://www.vortechsuperchargers.com/page.php?id=33511
To get 6psi we were running a 2.75" pulley (Which is what VF use on their 9psi setups). Will need to go through my notes again, but with that being said, ESS have a different bracket and set up so their pulley sizes may vary, but if they are anywhere near the VF sizes, then you may need to increase your Crank Pulley size, which I do recall that the ESS kit does anyway.

Yes, that makes sense.
The ESS kit has a different size pulley on the Vortech charger compared to the VF kit due to the crank pulley being bigger with the ESS kit. The smallest size pulley Vortech sells is 2.65" if I recall, and that will barely get you 7psi up here with a V3 charger and stock crank pulley.
ESS said the reason they change the crank pulley instead of the supercharger pulley was to eliminate slip. A 2.65" pulley is very small and you will need to put a lot of stress on the belt to keep it tight. I upgraded my belt tensioner to the one VF sells to insure no belt slip would occur.
If you are looking to up your boost, you may need to read more into changing that crank pulley I'm afraid.

It's complete and gives 10psi boost on stock S54 running gear
