Supercharger Project Update, SSX and MKII Exhaust

September 9, 2007

Hi all,

It’s about time I send a bit of an update on the progress of the twin-screw supercharger kit I am developing for the RX-8.

Here are a couple of photos under the bonnet (hood) of my car when I had just finished a trial fitment of the the new components under development.

My main mule to date for this development has been an RX-8 engine on a stand or sitting on the bench.  This has been invaluable, and I thank the legendary Phil Laird from Graphic Skills Racing for letting me borrow what I have needed.

From time to time I have also had to remove various parts from my car to plan and measure for where various components will be located and where plumbing will go.  During the past week, I removed the “top half” of the intake manifold and did a trial fitment to the engine, including the supercharger and mounting brackets, intake plenum and blower discharge cowling.  All went well, including a trial fitment of the beginnings of the pipework to the intercooler.  Since this was only a trial fitment, I wanted to get the car back on the road, and spent a couple of hours fitting all the removed equipment.  She started first go, so I was prety happy with that, considering the amount of fittings, both mechanical and electrical that I disconnected.

The photo’s might look a bit boring, but they do demonstrate the kit will fit with all standard covers in place.  I have not seen (or been made aware of) a FI kit for the RX-8 to date that has been able to claim that.  But don’t worry, when the engine cover is removed, there is plenty to show off for those who like to do that as well.  All will be revealed when I have this on display at SSX later this month.

Speaking of SSX (Seven Stock 10), I will be taking with me a special example of my updated “MKII” version of the Hymee Enhanced RX-8 cat-back sports exhaust.  All new systems now have the Hymee brand embossed in the muffler casings, and also have a nice stainless steel ID tag that has a serial number laser engraved into it.

This is a special example to celebrate 40 years of Mazda’s Rotary Engine development, so it wears the serial number 40.  I decided to run an auction for this unit, so I stuck it on eBay.  The auction is due to close at noon on the Sunday of SSX (September 23rd), which is about 5:00am Monday morning back home in Australia.  The most I could run the listing for was 10 days, so it won’t come on-line until about the 14th of this month.  I can’t post the link yet, as she isn’t available yet!

I’ve also held onto serial number 8 for other collectors to have the opportunity to own.  It is on eBay now, and you can find it by following this link.

Anyway, I hope that is a good update for the week.  Counting down the sleeps until I fly to LA and on to SSX.

Cheers,
Hymee.
