underbody diffuser
well I know I've posted a few things on the topic on other threads and said I would start something separate as I went through the steps of replacing/and/or/improving the efficiency of the underbody.
Its the 2nd weekend I've pulled the car up on ramps to look at things and pull a good chunk of parts off the car to see what I'm working with and where I may go with this project.
I'll pull it up again and actually take pics next time when I start shaping out some templates.
I'll update this as things progress (albeit slowly), but my first thought is this body needs alot of seam welding help.
well heres my first write up
well just an update after inspecting everything. I don't know how different the GDs are to the GE8's. To be honest, I'm not seeing alot of areas to improve upon. I have a base so maybe the rear sport bumper hangs down more and would benifit more from a rear diffuser, that I cannot say. but the stock base one is pretty decent, a bit of improvement could be had making an extension for the passenger side rear, and if you reworked the exhaust a bit could be done with the drivers side.
as far as mid body, the biggest gains for efficiency would be to panel off the passenger side, thats a biggie. not much can be done with the drivers side as the exhaust is routed there. and the center is just a gas tank. If you wanted to be extreme you could pull the tank and drop in a fuel cell, reroute the exhaust straight down the center and flat panel the whole damn thing. But if your going that far, you might as well cut out the spare tire well, work in a replacement brace and you could do a full on gt3 style venturi rear diffuser (not that theres any point to that).
For the front, theres already a good start on the underbody and it looks like there are already factory mounts for paneling over the bottom of the engine. I'm already trying to scheme how much venting and where would be needed to take advantage of this. Also it wouldn't be too difficult to add some brake ducting.
