One of the 2nd elements installed. Need to hit the store for more bolts.
I agree, the second element completely changes the look. Looking to source another element for a third one.That second element totally changes the look. Makes it more aggressive and the proportions look better.
Who supplied the elements and what sizes?
Thanks! We'll see how it does on downforce. It may be replaced with a wing that comes with actual downforce data later on.Dang that looks nice! Pretty sure the double element will provide significant downforce if angled properly. No floaty front end on your Goblin!
Anyone know of a university with a Goblin sized wind tunnel?Thanks! We'll see how it does on downforce. It may be replaced with a wing that comes with actual downforce data later on.
I taped some yarn tufts to different parts of the wing, element and endplate to try and get some video of what's actually going on. But of course the battery died. Another day.
A plastic cup and a fan should do it.Anyone know of a university with a Goblin sized wind tunnel?
There are quite a few places (both college and commercial) that have rentable tunnels that range from $500-$2000/hr depending on size and capabilities, like max wind speed.Anyone know of a university with a Goblin sized wind tunnel?
That's not a half bad idea. Tunnel time on someone else's dime. The nose/hood template is loosely based off of FSAE anyways.Was just thinking that if an engineering student needed an idea for a project…
Thoughts of Ferris Bueller’s Day Off just went through my mind……..That's not a half bad idea. Tunnel time on someone else's dime. The nose/hood template is loosely based off of FSAE anyways.
Now I just need to find a student I trust with my car.
The great Goblin Guru Lonny once told me that the turbulence behind the rear of the car is so dirty that the wing is essentially useless at the rear - except for the ends of it where clean air strikes it......Love the dual element front wing. I've been rolling a similar idea around in my head for whenever I get to it, but with a split design so it can be mounted closer in to the nose and thus tucked up closer to the tires. I'm thinking that sort of set up could route some air up and over the tires instead of having it smash into them.
Getting slightly off topic, but I wonder how many feasible opportunities there are to improve aerodynamics on a goblin. I don't think anybody is under the impression that this is a strong suit for these cars but having one that is running very rich as mine is right now has brought to light just how much of an issue it is. There's a huge amount of exhaust gas that makes it way back up into the cockpit area which really surprised me. That seems indicative of even more turbulence in the air around the car than I would have expected.
A cylinder is considered one of the worst objects for creating drag and turbulent air. The goblin doesn't set itself up for success being an exposed chassis made of cylinders haha. Best bet is to add more body work I'd think.Love the dual element front wing.

This really interests me too, as everyone's "the car feels so much better" is hard to quantify without some data.I'm curious if you could measure a difference in ride height at highway speed with and without the wing?
