Hey skidd, Are you using the GT500 splitter with this setup or the 2010? What If you fabricated an aluminum sheet to extend the 05 stock pan to the Kmember? Also have you done anything in the rear? The wide open rear fascia has got to have a ton of drag. I saw a Kenny Brown mustang awhile back that had vents in the back of the rear fascia to disipate the high pressure there. Had to of helped...GA

Long story but its sqidd like “squid”. It’s a motorcycle thing.
The splitter I have on there is the OEM 07-09 GT500 one.
The 05 GT pan is more of a splash guard than anything else. Its effects if anything are minimal. I was originally planning on laying up a carbon belly pan that went from the bumper cover back to the K-member after I got a look under an Aston Martin Vantage but before I tackled the project I saw under the 2010 GT. The two biggest advantages with the 2010 GT setup is that it goes the entire width of the bumper cover which seals everything up. And secondly the section that has the louvers that goes from the core support to the K-member is contoured so as the air under the car rushes past it a low pressure zone is created which pulls air/heat out from behind the radiator which is exactly what the front of the car needed. The positive effect is two fold. One it pulls hot air out which is always good and two that low pressure zone removing air from the engine compartment reduces lift on the front of the car. The setup works real well with the GT bumper cover but works even better with the GT500 bumper cover and splitter. I know I sound smart but a friend of mine used to be the fab guy for a big Grand Am team and knows a whole lot about aero and how to make it work for you. He was going to be the one helping me lay the belly pan up. When he saw what Ford did he told me I would be an idiot not to just buy their stuff. The sheet of carbon to cover that area would be pretty pricy not to mention very time consuming. Doing it out of aluminum wouldn’t be very inexpensive either. Just the sheet you would need to buy if you wanted to do it in one piece would be about $175. And you haven’t made one cut yet. And there is no way we would be able to contour or place the louvers as well as Ford did. Their recourses are a bit deeper than ours. Ford obviously did it because of floppy hood complaints. They spent some real time and money addressing the issue. The price of their parts is minor I comparison.
And you hit the nail on the head in the rear. It needs a diffuser bad. I spent a lot of time reading about how to design one correctly for a certain application and was planning on making one of those too. Lucky me one of the tuner shops tackled the Mustang market and just released one that is functional and not just a decoration. They way the designed it is spot on. These guys have a sweet setup. From what I have read it could be worth up to as much as 10mph:
Yea,,, I knew it was Sqidd, sorry, got in a hurry and it came out Sk......
How much of an affect do you think the vents in the GT500 hood have on this whole wind thing. I was thinking that it kinda does the same thing as the bottom tray by allowing the high pressure to escape from under the hood and also allows air thru the radiator eaisier. I have noticed that my car cools better since I put the hood on with just the stock lower pan. It also is pretty solid at high speeds, but I have only been too 120 or so. The air can either go up thru the hood vents or down under the car if you have the 2010 pan. Having both is probably the best of both worlds.
I like the APR rear diffuser but its a bit salty...Trying to figure out where it attaches to in the front? Does the leading edge attache to the bottom the trunk?

Just giving you a hard time. its a thing I do every once in a while

I’ve wanted some sort of heat/air extraction hood for two years now. I never found one I liked aside from the GT500 one. I never picked one up because they were always so much money and I hate dealing with paint. I ended up getting the 2010 belly stuff first and that made a huge difference with air management. I was real happy with the results. Then I got the hood on and was quite surprised how much improvement that made too. There’s probably a vacuum I the engine compartment now!

I have not looked into it too far because I am not ready to pull the trigger anyway. By the size of it I couldn’t imagine that it makes it all the way to the fuel tank. Of course that would be ideal if it ran under the axle and still had ground clearance but I find that unlikely (just a guess, I haven’t gotten under there and put a eye on it). It’s a lot more likely that would work better with a IRS car. I’m sure that there will always be compromises with a solid axle car.
I suspect that it starts behind the axle. And if so from the pictures it looks like its possible it may “scoop” up some unwanted air at the front. Maybe that’s the reason for the vents at the rear of the diffuser where it meets the bumper cover. If it was set up in a way that it could scoop up a bit of air it probably wouldn’t be much though. The air behind the rear end will be turbulent and barely moving compared to the air running under the car and under the axle. Nothing a small piece of aluminum that kicks up a bit at the front of the splitter won’t fix.
