Was the problem the cut hose?  Or anything else?

 

id make a shield for that hose.  In case that belt flops around under certain conditions and hits the hose again

Yeah, I'll probably work on a shield. I have not found why the car is running rough yet. I'm thinking I need to get my injectors tested at the moment. I have replaced the TPS and there is no change. I've ruled out the wideband O2 sensor.

Time to make a list of things to tackle during the winter.

Question for everyone: I want to build a dual element wing off the back supported by the end plates. Below is my crude drawing in GIMP of what it might look like. The black lines will be 1/8" wire rope to keep the rear element square and supported from being pushed backward by air. The elements will be two 70" Wing Logic wings with the gurney flat ground down flat. These have a 9 7/8" chord. I already had one of their wings (current setup pictured at bottom), so I just bought another one. I expect the width of the end plates (front to back) to be about 14" - 16". I'll probably push the element up a little higher than my crude picture, I want clean air over the top of the car hitting the wing, but this image should work for illustration.

The question is, does anyone have a suggestion on how thick the alluminum end plates should be. I'm going to head to my local supermarket of metals and buy a sheet of aluminum to cut and bend to the size I want, but I'm wondering if anyone has any suggestions now how thick it should be.

I asked a similar question and 1/4" was the answer

Mount it higher if possible to get it into clean air. The round tubes of your cage are very turbulent.

I started working on my cardboard aided design today and am wondering about how to support this thing properly. According to the CFD data from the wing manufacturer, this will produce around 600 lbs of downforce at 150 MPH. It's dual element, so now I need to worry about supporting 1,200 lbs. I was thinking about using 3/16" aluminum plate just to make it easier to bend...but not sure that will work. The end plate is 20" from front to back and I'm not planning on making window cuttouts on the end plates at this point. I could add gussets to strengthen the bends, but that's not very aerodynamic. I could bend with a pipe so that the bends are more rounded and not sharp. I can also use wire rope as earlier mentioned to help pull it upwards if I go to the right parts of the cage.  I'm currious about your thoughts. Here's a bunch of pictures from angles and a youtube walk around. https://youtu.be/mfqTKxfeqxc

I imagine this car is super fun to drive.

It took a couple of months, but I finally completed it.

I'm a terrible drag racer, but I took the kart out just to see what I could do.
