AWWW, you removed the VCP sticker, that'll cost you at least 20 HP :cool:

I had a busy day yesterday. I loaded up the 818R on the race trailer and towed it over to my friend's (Andrew) house. We are friends from college and race a Chumpcar E30 together. He also races Spec E30.
The 7' long Race Ramps worked perfectly with my trailer. I also kept my existing extended flip out on the trailer door (Bob in Cincy's idea) so the approach was even better. Thanks Bob.
"Farmer Engineering" has started on the rear wing mount. He is a much better welder than I am. We went through a game plan for fabbing the mount up. He also had some good ideas on more support for the rear bumper (essentially there really is none from FFR- unless if you call a few rivets and 6 screws support).
The best quote from him was... "I usually get my best fabricating ideas after a couple of beers working on it at night".... lol

Side note: our local PCA region had a car show/ Oktoberfest party last night. My Spyder was voted "Best of Show" out of 60+ Porsches. :) (I washed it for the first time in 6 months..... lol)

RE, longislandwrx's pic, it seems you have not utilized the side scoops. Do you have plans for them?
I'm still looking at options. It looks like a rectangle 15"x11"x4" minimum would fit back there, in front of the rear wheel.
I have no plans as of yet. If Mechie comes out with some CF scoops i may jump on them. Being that the car has a A2W intercooler, I don't see the side vents as being as crucial. Depending on my oil temps, I will eventually throw a cooler behind the drivers side vent.Quote:

Your white is so shiny. Did you do anything to get that or is it just good lighting?
Haha- Yeah those are just the mini ramps so I can get a jack under it. It does look funky.Quote:

Looks awesome Chad.
on another note, has anyone considered extending the hood/bumper to reduce the exposure of the headlights?
this picture was just a perfect example.

Just curious, you didn't vent the hood. The blue FFr car has small vents, the red are large. I am still up in the air myself. I would kind of like to see the red car in the wind tunnel to see how the aero is in the front end.
What aluminum panels did you remove to get the most out of the vents? Obviously the rear side of the splash guard, but did you remove any of the other panels to let it breath more?
I just have not decided on the front hood cut outs yet. I don't know if I'm going big vents like the Red Car, or small vents like the blue car.
Brandon- I left off the rear splash guards and those rearward triangle pieces.
BTW- Rear wing mount has started.

Do you have any concerns with the tire kicking something into your water or brake lines with that aluminum panel removed?
Running Buttonwillows 13CW again for some redemption this Saturday with Speed Ventures. I'm trying to get my times down before meeting you out there ;)
I ran my brake lines down the center tunnel, and I have the aluminum coolant tubes. I'm not too worried. Time will tell.Quote:

I finished the Rear Diffuser- I just need to pop it on when I get the car back.

As it stands I have the extra oil tank scavenge port connected to PCV. I need to get a hold of the guys over at element because I rather plug the hole up and keep the PCV from drawing air from the oil tank. The vent just goes to a filter right now but I am looking into a swirl tank. That vent spits little dirty oil grit balls everywhere
Chad, you ran the diffuser strakes to the rear, FFR ran them towards the front of the diffuser, any theory concerning what works best? Does it really matter?
That rear diffuser doesn't look CF.

I don't know how they have ducted the air under the hood. Looking at mine, with all of the inner shielding in place there is not much area for the air to get out. I thing that is why they added the larger vents. My question would be, Do they loose or gain down force with the disruption of air going over the hood. I am hoping they can do another wind tunnel to test their new pieces and this venting.
Don't forget my car has the door vents. Those will dump alot of air out too.
My rear diffuser is the crappy Gen 1 "carbon fiber" piece. I painted the bottom black since it was fiberglass ugly (not that you will really see it). I based the strakes off of other race cars I see. Granted, the lowest pressure is at the start of the diffuser, but there is no real angle at the start of the FFR diffuser, so I pushed them back.
Joe at FFR is sending me the flat bottom aluminum since my car did not come with it. With the Dry sump, I can have a total flat bottom race car.
Hi ChadQuote:

Since opening doors is out, Wayne and I were looking at the possibility of simply trimming the doors at an angle so the fronts leave more room overall. I have not dry fit or even mocked them up that way, but it seems like a valid option. It would have somewhat the Viper look...

Did you just rivet the strakes to the diffuser? I can't quite make out the way you mounted the strakes. It is just a pit too much black to tell.
Thanks Bob- I should of waited then :) I can just move or extend them. I like the idea of extending them back (or towards the front of the car I should say).Quote:

Definitely interested in how this goes and your final design, I did not get the wing yet as I wanted to see how folks were going to mount it and have it secure.Quote:

I'm not an aerodynamics expert, but as I understand it, the strakes are to create laminar flow, minimizing turbulence as the air exiting the diffuser is decelerated and rejoins the ambient flow. Therefore, I would think running the strakes to end, as Chad did, would be more effective. Looking at single chambered race diffusers that use strakes, they usually go all the way to the rear. It would take CFD or a wind-tunnel to definitively answer, and it probably doesn't make a huge difference, but I'll mount mine rearward simply because it looks cooler. :cool:Quote:

We will be adding a piece to act as a rear bumper (about 3 1/2 feet long). It will go into the channel in the bumper (above bottom vent). I didn't want to have it part of the wing structure, but it just works to go right off of it.
The Dry Sump oil tank will be hung off the driver side mount with custom mounts welded on.

More pictures- Oil tank mount is being worked on now. Once that is on, then we just need to weld on the wing mount channels and drill 4 holes. (removable wing)

Looking good, is the push bar going to be Looking strong enough for a toe hook ?Quote:

Chad, can we get a shot of it now from the inside with the bumper fascia on like you have above? Does the push bar sit within that little bumper channel formed in the fascia or is it flush with the lower portion of it?
Looks nice!
Best,

Wow! That's really cool. Is that 1.5" square steel or 1"?
Thanks Guys. I'm really happy with it. My Buddy Andrew thankfully likes doing this kind of stuff. I told him he should make a template and sell it as a kit. But every chassis would be different/not square.Quote:

We are using 1" square tubing 1/8" thick to match the chassis square tubing (FYI- the chassis square tubing is a little thinner than the 1/8th thickness we are using). Once it is fully welded and powder coated/painted, it will look like what should of been there originally from FFR for an R.
It will be plenty strong for a tow hook.
More progress on the Oil tank wing mount-

http://i.imgur.com/A1MazbZl.png
Its almost finished. We just need to weld in a small support to strengthen the bottom of the oil tank mount.
Next is the actual wing mount channels! Then after that, its time to fully weld everything up. Then we are done.
Looking real good, couple of questionsQuote:
