Should be able to. We have only just started development though :)

Cheers,
Hymee.

'twas my pleasure.

No. I guess that makes you first in the queue.

Cheers,
Hymee.

:D :D :D :cool:

I had better leave the mastercard at home!

That didn't win you any bonus points. :D

Priceless :D

How long's it to take to drive to Brissy from Sydney again..? lol

So, uh...Hymee. You're approaching the 4000 post mark. What kind of crazy, innovative product will you be revealing then? C'mon, you can tell us, it'll be our...not so little secret :p
Make sure you take video of the car with new pulleys! (or is it pullies? The world may never know :D )

about 10.5 hours, with half a dozen meal/toilet breaks :D

What what what? You put forced induction on an N/A car and your insurance company says 'ok no problemo'???? How can this be? It would be awesome but surely they are a bit thick or something and don't know what a supercharger is.
I am going to try it with mine, I am sure they would spit the dummy and double the premium :)

RE: insurance I have just been looking into the legality of the Supercharger conversion as I thought I read a while back that you weren't permitted to modify the induction side of cars post 1987, and as such probably wouldn't be covered in the event of an accident, even if you did sneak the supercharger onto your insurance policy.

However I can't seem to find anything like that in the current ADR's. Infact it seems that as long as emmisions and noise ADR's are still complied with, (all original emmissions gear fitted and functional) and for 'substantial' power upgrades, braking ADR's are still complied with you are OK to bolt on a supercharger.

In the light vehicle modification guide:

http://www.rta.nsw.gov.au/registrati.../vsi/vsi06.pdf

It appears that the Supercharger would come under the owner certified (minor) modification category, so no engineering certificate would be required. Do you guys read it that way?

I just took Hymee's car for a short spin for the first time. There are a few things I loved about the drive:
1. The car is much more responsive. It feels like there is no drive by wire... you put your foot down and there is instant response. With a stock car, to me it feels like there is a bit of lag between when you put the foot down and you get a response. This is gone.
2. The car pulls the whole time... right through the rev range. You're pushed back into your seat the whole time - something you only get at high RPMs in a NA Renesis.
3. There is definitely more torque... driveability under light acceleration is improved. I could drive at low RPMs under light throttle in a higher gear than I could in a stock car.

No surprises here I suppose :). It was a treat to drive. I'm personally most interested in improvement in the low end and that's exactly what I felt.

Sounding like another weekend in surfers and another long explanation at customs......well done old son, can't wait for a closer look at wakefield, where we can be sure of nice "cool" air!

Numbers ?!?!

is the car running at the intended boost or is it running a lower boost for development?

We are running a far bit lower boost at the moment than we ultimatley will.

The Motec MAP sensor is showing about 150kPa give or take. That is about 7 PSI boost.

I should grab a screen shot. It is 7PSI when you crack the throttle open, at whatever RPM. And it stays that way all the way through to redline :D

We will not dyno it until we fit an intercooler :eek:

Yes, I have been able to drive all this time without an intercooler. The tune is very conservative in terms of timing. We need to maintain an adequate safety factor. Just imagine when we get her intercooled, and tuned up "better".

Cheers,
Hymee.

what type of intercooler are you going to use?

We will probably run with a water-air to initially, and offer a air-air FMIC to those customers who would prefer one.

Cheers,
Hymee.

What are the advantages/disadvantages to each?

according to kenne bell, their superchargers dont need an intercooler, as the charge air is about 60 F cooler than competitorsl chargers. it may be different with your setup, but relating some info i found on their website

They are comparing their units to a roots supercharger which is really inefficient. A roots unit would need an intercooler to make the same amount of power that a twin screw makes without one. However like all superchargers/turbochargers, the twin screw still heats up the air. It is closer to a good turbo in this regards. To say you don't need an intercooler is a little misleading because it doesn't specify at what boost levels. You can hit a certain power level with no intercooler but it doesn't mean that you couldn't make more with an intercooler. You could. For low boost levels you might not see much of an advantage due to a slight pressure drop in an intercooler but the more boost you run the more you need one.

Slight pressure drop due to the contraction of the air as it is cooled, right?

And, we won't talk about the advantages of a Cold Air Intake. ;) Kenne Bell has done that well enough, and goes as far as voiding the warranty if its not done, or even if its not done correctly, right? http://www.kennebell.net/techinfo/ge...AirWARNING.pdf

sold. :D

heehee:

"The Kenne Bell Twin Screw Supercharger is essentially an air compressor and an air tank combined. That is why it is so potent and capable of
generating full instant boost at the flick of the throttle at any engine rpm. It's akin to an air hose (throttle) connected to the air tank (supercharger). The
handle (trigger) regulates the air flow (boost) into the engine. Engine rpm has little to do with the boost delivery. Boost is regulated with the gas pedal.
Abasic law of physics tell us that all air is heated when compressed, regardless of the supercharger or turbocharger type. To lower the superchargers
air temperature at idle and cruise, we rely on a bypass valve which "dumps" the hot compressed air in back of the throttle body where it is
"decompressed" and the temp is thereby lowered with the help of the cooler incoming ambient air flow through the throttle body. Unfortunately, at idle
and cruise, the throttle body is closed or barely open thereby allowing relatively little new cool air flow into the supercharger. So, the last thing on this
planet that our supercharger needs is more hot 200° air from those ridiculous, useless, power robbing underhood "hot air" systems. LOSETHEMand
use a 4" or 5" hose (depending onHPlevel) to pull cool air out of the fenderwell just like all the OEM's, racers and the knowledgeable do."

Hymee,

Are you running a std six port intake manifold?

I'm interested in a modified intake which would allow me to reduce to overall height of the engine?

Regards
Andrew

Some of the intake runners are standard, but we have removed the big 90 degree plastic elbow that goes between the TB to the runners, and have fabricated our own (prototype at this stage) between the blower and the said intake runners.

Cheers,
Hymee.

Thanks,

So you've kept the alloy casting std and not cut it down.

Andrew
