Now if they do gain 2 seconds it will be interesting as will show cfd working fine but christ they could of started with a better base, still with hrt if they manage to keep to their development plan and understand the setup aswell as they did last year they will be last but not stone dead last
If they can get everything ready and working in Turkey, it should add up to a very substantial difference in performance - they need to increase their downforce levels substantially, since they are really struggling at the moment to eke any more performance out of the car in its current configuration. However, whether they can get everything to work properly immediately is another matter.
Last year, when a number of teams introduced their versions of a blown diffuser, several of them hit problems - McLaren and Mercedes had a few problems with localised heat build up (warping floors due to thermal expansion and localised burning of bodywork), and Williams had a few problems with burning bodywork in China, which is why they ditched the blown diffuser they'd used in practise for the Malaysian spec floor. It's a substantial change to make to the diffuser and exhaust layout, and given that it is a very difficult environment to model (since you have to factor in the airflow from the bodywork in front, hot air from the cooling systems, turbulent air from the tyres etc.), it might take more than one attempt to perfect.
That said, I expect that Geoff Willis is not exactly hanging around - there have been a few rumours that he is working on a major upgrade package, which seems to be scheduled for around the Monaco GP. Glock himself said that they Virgin Racing needed to bring in a major upgrade package to avoid slipping behind HRT; considering that HRT could make big gains just through set up work, adding a major upgrade on top of that could present Virgin Racing with a real challenge.
As for why these upgrades are coming in now, and were not in place earlier. Perhaps part of the reason has simply been that Virgin Racing have been tied up with their hydraulics system - they seem to have got to grips with the Xtrac transmission now, but resolving its problems seem to have taken up a fair bit of time and effort. Secondly, we know that Nick Wirth's company have been overhauling their CFD capabilities recently, and it's probably the case that only now are they able to significantly increase the amount of effort and design iterations that they can do.
And another reason why the updates may be coming more rapidly is because Joe Saward has posted a few comments about recent restructuring by the teams - where he notes that Virgin Racing had raised a few complaints about Wirth and his technical team. It's amazing how much harder you can focus on something when you fear that your job is on the line...
