Kelly Racing completes successful aero test day at Winton
Kelly Racing completed its first full in-season Supercars test day on Tuesday at Winton Raceway, with the main aim of the day to evaluate the aerodynamic change made by the team last week. All four cars and primary drivers were on track for the day and together covered over 1200km, running through around 100 different setup changes.
The aerodynamic change was instantly noticeable by the drivers with the balance of the car shifted more rear-wards, providing more stability on corner entry. The change also seemed to yield more lap time consistency across the team.
While the team learned a lot at yesterday's test day about this new package and is going into the next round feeling positive, there are still plenty of questions that need answering. Given the fresh surface at Winton Raceway and the high levels of front-end grip it provides, the team felt it was difficult to judge just how much of an impact the aero change has made on overall front end grip.
Winton's short straights also made it tricky to judge how much additional drag was being created by the new rear gurney flap.
Overall it was a positive day and the team is confident that it is heading in the right direction, but there is still a lot of work and data analysis to do in order to come up with a competitive package for the OTR SuperSprint next week where we'll see how the updated Altima stacks up against the competition.
Kelly Racing Team quotes
Scott Sinclair, General Manager – Racing
"Understanding the new aero package was the primary key of the day so we got through over 1200km and over 100 different setup changes. So the real work starts now in the next week before we get to Tailem Bend to understand how we want to roll out for the next race weekend with a setup that's as good as we can get it."
"We got through everything we wanted to and the drivers are reasonably positive about the change but until we're up against our competitors at Tailem Bend we really won't know where we sit."
"It certainly has done what we expected in moving the aero balance more rearwards and given the drivers a bit more comfort with the package but Winton typically has a lot of front grip so the front grip that we've lost as a result of moving the aero more rearwards we weren't really able to quantify so until we get to a more typical track where it's front grip limited we won't know how much of an impact shifting the balance rearwards has had."

"I was pretty comfortable straight out of the box with the new aero, it wasn't something where we needed to dial it into a window, it came to life pretty quickly which I think was the main aim from the changes - to make it a little bit more user friendly and it certainly achieved that."
"Yesterday the pace was good, it was nice and tunable and all in all it was a really positive day. It's worth noting that leaving the day you have to be a little bit cautious when doing a test day at Winton just through it being a very unique track and quite changeable conditions, we've got to keep an open mind when we leave Winton into Tailem Bend to see how the car presents itself there."
"All in all, the work that the guys have done will pay off in making the car a little bit more user-friendly from a setup and also a driving point of view. The car that we've had this year up until now has been reasonably quick at times but from a driving point of view it's been extremely difficult to extract that time out of it, with it being super sensitive to inputs and how it reacts."
"Whereas last year's car and certainly the one we felt at this test day it seems to be slightly more forgiving and easier to put a closer to perfect lap together and that's what is important in this game is getting the most out of the car in qualifying and having a car that is reasonably easy to extract a decent lap from. It's not doing anything nasty at the moment whereas the car we've had it tends to bight you pretty quickly."
"Certainly the track degradation is pretty low at Winton, which is actually good from a testing point of view because you can replicate the lap times each run whereas you got to places like Darwin and others and every time you run the car you drop a tenth or two, then when you make a change it becomes difficult to quantify whether the tyre deg has hurt the lap time or the track has. So that was really good for us to make small changes lap after lap and see what it was doing."
"In saying that, it doesn't replicate a lot of the tracks that we go to so we have to be a little bit careful with some of the results we've got and keep an open mind heading to the other tracks."
