Not this time but. DJRTP 1st and daylight 2nd. Might see a non DJRTP, 888, PRA car take a minor placing, but that's it.
I agree with you about the circuit from a spectators point of view.
As for DJRTP, I guess we will find out how they are getting their performance - whether their power is dominant, whether set-up/handling is dominant, or if they are just all-round good. I'm hoping some of the teams with a bit less power will be closer to the front at this fairly tight circuit.

DJR don't have a more powerful engine than the rest, it's all to do with how they set the aero and geometries, and because of that I still can't see them being beaten in Winton because they appear to have a very good understanding of the fundamentals of the car and how to make it perform in a variety of conditions.

It'd be interesting to compare the DJRTP cars to the PRA ones, particularly around the packaging of the underside of the car, and the way the aero is managed.

I've already noticed one or two little things...

I think it is a very slippery car and Winton by its nature is more point and squirt, so it has the potential to throw up a different result, but we'll see!

irrespective of previous outings, basically Winton is flat track racing,
Not a high speed circuit
re tune to the car for short sharp racing , make it wide where you can

DJRTP, RBHRT, BJR GRM, etc etc should already know from previous visits to this little place in Vic

Does anything think then, that there's some correlation to street circuits here?

Adelaide is so much faster. Winton and Calder for example are different animals IMO

just a point of clarity, Winton has a longer racing surface than Darwin, Pukekohe, Symmons Plains, Barbagallo, Hidden Valley and only 100 metres shorter than Queensland Raceway

I take it the rules are free regarding how you duct air through and out of the radiators?

I recall, until recently, some of the F1 teams just let the air spill willy nilly through their sidepods and out the exits... until they all started to twig on gains to be had by reducing internal drag??

Surely the underside aero rules (as in not allowed) are pretty strict though? Are you suggesting DJRTP have arranged other components in such a way that they serve an aerodynamic purpose?

Location of transaxle coolers, exhaust design, and so on, can have an effect on underbody aero. Teams are free to place them wherever, so there are potential gains to be had.

DJRTP also seems to have additional bracing in their bonnets across the hump, that PRA does not. Suggesting that there might have been a flexing issue with the bonnet itself, that may be disturbing the aero.

Every single external facing component on a Supercar has an aerodynamic purpose.

Gibson Motorsport way back when built those diffuser boxes for the fuel tanks back in the day, or crafted their oil cooler solutions to send air where they wanted it to go.

Mr Lacroix was the master at this... anyone remember the Xbox car being a rocket in a straight line at Bathurst... with the same engine that was in #888 earlier in that season... aero holes closed up, cambers and castors closed in... big work.. successful work...

I remember the 1999 Wynns VT's were the only cars to run rear exiting exhausts.
Was this related? Or was this Group A stuff?

They worked well, until the car got a hit in the rear, and crinkled the pipes.

I remember seeing them in parc ferme in 99 after the Sandown sprint round. Looked and sounded a bit special after a few boot roots.
