V8 aero change

pplater · 22 Mar 2004, 01:35 (Ref:914546)

V8 supercars always seem to have troble with debris etc. clogging their radiator vent. should they revise it, something more like this:

Now taht would be thinking...but given the idea has come from another manufacturer & series I doubt AVESCO will embrace it

pplater · 22 Mar 2004, 04:39 (Ref:914608)

Aero is controlled- standard across the board in V8s, isn't it?

Huh?

Nascar-like points?

Nascar-like franchise system.

Nascar-like "Busch Series".

Nascar-like shunt caused by Dumbrell in Adelaide.....

Funny, we used to see the Brock Mobil VP and the Seton PJ EB Group A cars with tape over the outer vents all the time.... I always wondered why, and then have wondered why since 94-95, they haven't done so...

Wouldn't rubbish still get in that intake shown? Maybe there would be no difference at all.

mixxer · 23 Mar 2004, 02:36 (Ref:915961)

they used to tape over the outside vents on some tracks only, it was to help generate heat in the front brakes. Aero kits are submitted by the manufacturers then TEGA signs off on them as far as I know AVESCO has nothing to do with it.

pplater · 23 Mar 2004, 02:37 (Ref:915962)

Senna- the side intakes are brakes ducts- carbon tubes that curve around behind the wheel to get air onto the brake discs... no big drama if it clogs.
The centre vent is- I think- for the engine radiator. If that blocks, the engine overheats and... bad things happen.
Sometimes it is good to heat up your brakes- optimum temperature or what have you for sprint races, qualifying.

Pete55, leaves lie on the track surface, and the V8sc front splitter (flat protruding bit) effectively scoops leaves into the radiator duct. What I am proposing is a radiator duct higher off the ground, one that would not take in as much leaf/plasstic bad etc debris.

DAVID PATERSON · 23 Mar 2004, 02:46 (Ref:915970)

Why not put a screen over each vent?

pplater · 23 Mar 2004, 02:48 (Ref:915972)

Dunno... there must be a good reason.

It seems so stupid to damage an expensive engine with something that seems easy to fix.

pplater · 23 Mar 2004, 03:07 (Ref:915984)

Here's the difference.

Senna05 · 23 Mar 2004, 03:14 (Ref:915992)

I think that would affect aero - look at the angle the ford/holden splitters have on the flat bit on the bottom - effectively a front wing.

But, I can see alot of positives - less broken engines, less aero - WOOHOO!

pplater · 23 Mar 2004, 03:16 (Ref:915996)

the m3 gtr appears to have it's brake ducts taped over, too.

I think i know why, have a look at the thick, heavy jacket the crewman is wearing. Racing brake pads don't work when they are cold.

Mattracer · 23 Mar 2004, 11:45 (Ref:916335)

The Canberra race was alwys pretty bad for leaves in the intake grilles but then the ambient temp was usually so cold it made not much difference at all.

I still cannot believe that Skaife's car made it at Bathurst in '02 with those plastic bags blocking the intake. Fairly amazing really.

stoned pony · 24 Mar 2004, 00:30 (Ref:917264)

The fix seems fairly simple - go to the hardware store, buy a metre or so of flyscreen mesh and run it across the radiator or even over the intakes. Leaves hit a flat surface and are blown away to the sides or drop off when the car stops.
Or are V8 Supertaxis too high tech for that?

pplater · 24 Mar 2004, 00:36 (Ref:917272)

I think they would sooner try a flyscreen than an aero change.

stoned pony · 24 Mar 2004, 01:21 (Ref:917296)

Or would AVESCO

stoned pony · 24 Mar 2004, 01:22 (Ref:917298)

Let me finish that (damn computer, behave before I put a brick through your screen!). Would AVESCO see flyscreen mesh as an aero change?

pplater · 24 Mar 2004, 01:26 (Ref:917301)

I understand that teams cannot alter the aero of the cars. Only things like gurney flap and wing angle adjusments are permitted.

I don't think a team would be allowed to trial mesh without the blessing of avesco.

pete55 · 24 Mar 2004, 01:29 (Ref:917304)

Can't they just string wire from top to bottom or even across the opening to stop debris getting into the intake.
Also i'm not convinced you wouldn't get as much debris into the intake, especially if you are following other cars which are flicking it up in the air.

scooby_au · 24 Mar 2004, 02:01 (Ref:917331)

i remember seeing one solution that i think team dynamik had for last years bathurst. It had 2 or 3 evenly spaced vertical wires strung out across the front main intake so that if a plastic bag was collected it would fold flat, minimising the area of coverage.

so yea, looks like its already been done before? or have new avesco regulations come in since last year?

pplater · 24 Mar 2004, 02:29 (Ref:917344)

or perhaps they feel that it is unlikely to damage an engine in sprint races...

stoned pony · 24 Mar 2004, 05:03 (Ref:917410)

Two or three vertically-spaced wires might grab a plastic bag but they won't stop leaves and grass and the like. I'll stick with the flywire mesh idea.
