Paul. Don’t be coy. I know you made your way two posts down where I compared the before and after weights of the splitters.

Two pins at the back and two cable struts up front and it’s on. No drama but I alway keep a sport beverage or two with me, banned or not. :cheers:

That is hurtful, Paul.

And I did offer beers.... granted, it was at 11:30am. :cheers:

Speaking of Paul being coy and Dave handling tools...whatever happened with this? It looks like a wing only smaller, do tell.

He built a cinder block shelf system and that's where he stores his shoes now. Very "racey"

Nope. I used recycled barn timbers to support the carbon and I store eye patches and bottles of dry eye fluid on the shelf.

It’s a 72” top mount wing from AJ Hartman, now RHR performance.

It should produce significantly more downforce with far less drag than the current wing.

It has some really noce build quality features suck as this gurney flap channel.

Very nice! Any numbers on expected downforce?

:thumbsup::flag2:

Sure

Here are some figures from AJ of a bottom mount wing with small endplates on a Porsche 944. There are so many variables with aerodynamics that you really don’t know the downforce of a wing onbyour car unless there is testing of it on your exact vehicle.

The top mount lessens the drag associated with the wing amd also increases the amount of downforce but AJ has never posted specific charts of the gains.

Similarily the larger endplates also increase the downforce as represented by this chart. AJ and his bussiness partner Olaaf (the engineer) ran a bunch of CFD scenarios to optimize the sizing and shape.

I have a Gurney flap on mine and on T-Hill the first time out I was seeing about 125mph on the front straight and avg speeds of just under 80mph and minimum speeds of about 50mph. So look at 50-130mph or even more specifically 80-130mph with a girney flap for likely downforce numbers. But with the top mount and larger optimized endplates I’d say from what AJ had published another 15% is likely.

:headscratch: Curious, by chance does Hartman make Torino rudders?


:peepwall:

None in production but if you send him a template he’d probably make anything; even STI parts. :action-smiley-027:
