Aerodynamics on front clip

Apologies if already discussed in the past, but noticed a reference to this article in the Noble forum and wondered how relevant it is to Ultimas ?

Mmmmm, interesting..... awaits comments from the group....

I reckon as only a seemingly tiny proportion of Ultimas go on track it probably is a little irrelevant anyway.

Of those owners that take it on track, there would be better things they could do initially to get quicker laptimes without the complexity of changing the rake of the radiator.

If they've made all the changes possible, then make the radiator mod and notice the difference, they should get it in Britcar

Getting any air leaks eliminated around the rad area will certainly improve cooling even on a road car. This will certainly be an important factor in my parts of the woods

First of all thanks for posting the article its always interesting to see what the pros say and the tests produce. I agree with our friend from Switzerland detail work around the radiators to keep the airflow through the radiators and out the scoop is well worth the effort. Look at the picture of the Noble before it was modified why waste all the potential cooling #1 and why push it into the wheel wells which already have high pressure in them trying to lift the car. Some of the Daytona Prototypes run a wing in the rad outlet area that parallels the floor of the outlet scoop about 2 inchs up from the bottom. I spoke with one of the team aero guys and he indicated that it cleans up the air turbulence comming out of the scoop and makes it more laminar when it contacts the rear wing helping rear downforce and cutting some drag. It's true these cars are not purpose built race cars but if preformance didn't matter to the owner why build a GTR might as well drive a Volkswagen bus. Lee

We panelled the bulkhead directly behind the radiator for this reason, and have taken time to 'seal' the radiator entry as effectively as possible whilst not compromising the time it would take to remove the rad. Trying to find some larger louvres from the front which will increase front downforce but, judging from this article, may help to increase cooling too, as you are not 'fighting' the high pressure air from the wheel arches - something we had not considered.

interesting how the Noble in the article had ''louves '' in the front wings...
