fair enough, why I prefaced my post with "I dunno".......

like everything else, there's always improvements made over time.

Kevlar hey??...............added advantage of being bulletproof :lol:

hey with the hydraulic handbrake would that work on the road parked on a hill or is it a race only thing?

it would work for a time, from memory hydro handbrakes have a habit of creeping (ie: slowly releasing over time)

so while it will hold the car when you walk off, there's no guarantee that the car wont have rolled away when you get back.

however, since the hydro uses independant calipers, you may be able to have the hydro for track/skidpan, and still leave the cable handbrake to work off the other calipers.

Just leave the car in gear :wink:

I had a Subaru AWD that had a haudralic handbrake that would do just that on a hill. It could sit there for 8 hours and then all of a sudden you would see it slowly creeping down the hill, and it was always left in gear.

Alrighty then!!! Feast your eyes on this bit of kit!!!

Yup, the supercharger has landed and what a superb bit of kit it is!!! :twisted:

The plan of attack from here is as follows:
(1) During this week the engine will be prepared to receive the supercharger kit
(2) This Saturday will see the supercharger bolted to the engine
(3) Assess what other items are required before the engine can be sent out for testing and tuning

So stay tuned for more regular updates....

Cheers,
Danny

At first glance I thought your supercharger was "Hymen Enhanced" :lol:

Looks so nice. Black is the new polished/chrome.

Danny,
Thank-you for sharing your project with us. When I am in Brisbane next I will come over and wash it for you.

Regards.
Greg.

would this fit into a particular race category if you wanted to compete with it?

It's arrived!!

Can't wait to hear it 'whining'......

Love it!

So, on the black front panel I can see a hole for intake pipe to charger, a discharge from charger forward to (not shown) intercooler, then I reckon there's a very large diameter return from the cooler to a (not shown) pipe that connects to the intake system of the engine. In between these is the coke can sized thing. Is this a BOV or bypass? If it is, is the plumbing all sandwiched between the black front plate and the bits behind? Does something attach to the back of the coke can part?

A lot of thought must have gone into all this!!

What is the ratio of displacements SC to Engine? ie what boost is predicted excluding losses?

Julian, I don't know about enhanced....it would probably be better at removing them. :oops:

Thanks Dale. I hope to get a good run at the project over the Xmas period.

You don't have to wash it Greg. You're more than welcome to have a squiz.

No idea James. Probably an "Open" class of some sort. I haven't built the car to any class specific recipe.

Stu, if you can hear whinging coming from my car then my wife's probably in it! :lol:

...Just joking Sam! :oops:

She should certainly have a nice whine though! :twisted:

Mark, it is an internal bypass valve that is vacuum actuated. Yes the porting for it is in the plate sandwich. Yes there is almost 6 years of development in the design of the supercharger kit.

If I remember the figures Hymee told me for the prototype kit, as a direct drive pulley ratio comparison, we should see at least 0.8 bar (12 psi) with the current pulley diameter. With larger injectors a smaller dríven pulley will easily deliver a higher mass air flowrate. The proof will be on the engine dyno.

Danny
