    Completed some oil pans

    Nice work, but what application are they intended for? I have a Moroso Road Race pan. I had to modify it to keep oil flowing over and out of the trap-door diamond at hard breaking. I discovered this was a problem at a road course. Original. Modified. Dimples are for the oil pump bolts.
  2. I have used flickr to host my pictures. They give you space for 1000 pictures for free. After that you have to buy Pro membership. My bulid thread is 6 years old and 19 pages long. I just had to get Pro at new years, so it will last a long time until you have to get Pro. And Pro was ok priced, you do get discounts at a lot of webshops for camera and picture stuff. They also have an app, so you can upload pictures directly from the phone. Easy to use. Drag-and-drop uploading in the web browser.
  3. The floor at the seat riser is double bottomed, so SFCs cannot interfere. Convertible rockers will take up some real estate, but it should be minimal up on the seat riser. I cannot see that it should be a problem.
  4. So, your worst nightmare just happened to me. Here's how: I was at the local racetrack, going out for my first session of the weekend. Started slow, planning on a warm-up lap. So in the 3rd corner I just spin out ca 100 degrees and hit the armco. The car is then recoiled out and according to the driver behind me a 1/2 to 1 meter in the air. I then did a 360 degree spin in the sandtrap and a 180 on the tarmac before I rolled to a halt on the other side of the road. Both doors didn't open. So I roll down the window and crawls out. A guy comes up to me and tells me he blew a oil pressure coupling and left oil on the track. Boy, did I give him the evil eye. :cursing: Here I got my car ruined because of him not having his shit together when he got out on the track. I was very frustrated. I was later told that he had been wrenchin' the whole day, and had a loud knocking in his engine in the pits. Which he ignored. I also heard he blew the oil hose in the second corner but didn't stop, he ignored it and drove on, oiling the track. A guy (who's an driving instructor) in an M3 told me he only got saved by the ESP system in his car. I was frustrated that the actions of one guy who didn't consider the safety of others on the racetrack cost me my car. On the other hand I was glad that I didn't have fault in it. The guy in the car behind me said there was no way I could have saved the car in that spinout. He actually destroyed all his tires when he was breaking to stop for me. Crashsite as seen from ontop the salvage truck. There was a lot for oil on the track all the way down the hill and I spun out where the two people is standing. Back In the garage The shocktower bracing did a good job stopping the impact. I also believe the subframe connectors helped resist body twist. I also have the TCP X brace under the car between the subframe connectors. It's only metal. So begins the rebuild. Luckily, I was covered by insurance, but I'll probably invest some extra money in the car anyway - I already have thanks to Ebay - you know how these projects go! Luckily I didn't have a scratch on me. I did get a minor swelling from the shoulder belt (using the originals), but it was very minor. Just like 3 zips in row on my collar bone. Luckily I didn't carry much speed when I spun out, because it was only the warm-up lap.

    Gas Tank Pressure

    I replaced the cork with the foam from a plug in type gas cap that you get at gas stations. It sealed the tank, so I got fuel starvation. so I made a notch in it to let it vent. Didn't take much, and haven't had any spills since.
  6. Well, it used to be Candyapple red. These are some photos I got from an PO. I have more, but there are people in them, so I don't know if I should post them. The current color is a SEAT color called Rojo Dehli Effect. SEAT is owned by Volkswagen. This is the next to oldest picture I have of the car, Mt Home Air Force Base, Idaho, 1984. Newly restored in 1989. Gresham Theater, Portland. 1992. Mt. Tabor, Portland, 1993. The day I bought it. 03.13 2004. It had a similar color to what I have now. I had it photograpehed at a paint shop years ago with a 100% match to a Mazda color. But I don't know what it was called. It was painted that color after 1999, but had been a metallic red from 1995.

    S*it happens! :(

    Dude! I feel your pain. I actually turned away when I saw that first crash picture. DAMMIT THAT SUCKS!!

    Photo needed of installed 69 Fender Extension

    Yeah, I agree.

    69 front valance same as 1970?

    I don't think they are flush. There's a gap that is covered by the bumper. They need to match at the wheel arch. This is a repro valance. The OEMs fit better.

    The headlight bucket isn't supposed to be all one color. It should have a black-out area, painted by a brush. https://pin.it/cjyaxgzwhnsn63 http://www.concoursmustang.com/forum/index.php?topic=9875.0

    Nope. '69s got marker lights in them. '70 marker lights is in the fender.

    Fastback inner rockers

    I think the meaning of post #24 is that the method applied is wrong. As in adding SFCs will do nothing for radiator support flexibility. I can very well believe that. But it will do a lot for the chassis. And the method applied misses that. The setup is the problem. The frame is supported by 3 jack stands. The whole of the chassis isn't available for flexing because it is locked in place. He is just measuring flex in the front frame rail, not the whole unibody. When the shock towers and Monte Carlo bar was in place, that load was spread across a larger area. When removed, and the same force applied will show more flex because the area it is applied to is less (limited). The 25% torsional stiffness credited to the MC bar isn't because the MC bar is so immensely strong. It's just a piece of steel. It is because the MC Bar allows the frame rails to be connected to a larger area. He should have put the car on it's suspension, but with strut rods instead of shock absorbers and springs. That way, the frame itself would not be supported at any given point, and free to flex all the way from front to back.

    Did you see all the videos? There's a playlist with 13 episodes. Ep 9 shows retesting at Multimatic for damper tuning. The Videos show re testing on the 4-post rig, and the Multimatic people at the track for real world testing. The job was done right. No, they do not give away their test results, just as they don't with the spring rates and the damper valving. That way a competitor would get them for free. I'm sure the hours at Multimatic wasn't free. I'm telling you, all you have to do is drive a car before and after getting SFCs installed. If you have, we wouldn't have this discussion. It is a night and day experience. The Barracuda and the Mustang have differences, but they both are unibodies with separate front and rear framerails. How supposedly one benefits form SFCs and the other don't, you'd have to explain to me. Well, apart from removing the shock towers. All the testing done in the "garage test" is meaningless according to post #24 on that tread.

    The main difference between the Barracuda and the Mustang, is that the Barracuda uses torsion bars instead of coil springs. So the tower of the Barracuda is a lot smaller, 'cause they only house the dampers. The transmission tunnel support is quite a lot beefier, because it houses the torsion bar housings too. The Barracuda does not have torque boxes, only the Hemi cars had that. My brother's Barracuda does not have torque boxes. The XV Motorsport kit that was sold to the public did not have the boxing of the upper rad support shown in the videos. They did have a Monte Carlo/Export brace that was mounted to the inner fenders and fire wall. All in all, I'd say the Barracuda weaker in stock form. I remember driving My brothers car when it was stock. On S-corners with a lot of camber, the fenders would visibly lift and dip. It was very soft in the front. This was with a 340 small block. The rear is quite strong. The Barracuda actually have a roll-over protection bar just over the rear window. So my experience with both cars is that the Barracuda was a worse starting point, and that the modifications XV did is applicable to the Mustang. Sean Hyland made at least a Mustang prototype with the XV suspension. I think it was a '66 Fastback. But the XV stuff was very expensive, so they didn't sell in the volumes they needed to survive.

    It's all there in the videos I linked. It shows all the development of the suspension packages. The result of the testing was that they used SFCs, rad support bracing and shock tower-to-firewall to improve torsional stiffness. If the guys with the resources tell you SFCs works, and the guy "without" resources tell you they don't, who are you going with?

    As I said, I don't have much faith in that test. I do have faith in Multimatic's 4-post chassis rig.

    I disagree. LOL :D

    True. But in a crash, we are talking about kinetic energy. It will dissipate by taking other forms like heat or sound. It's not like the impact (force) of the crash bounces around like in a pinball machine until it can bend or break something to bleed off energy. Crash force is one thing, it is what it is. The energy in that force is another. But we are getting off topic here.
  21. fvike

    Fastback inner rockers

    Well, that is a entirely different thing. Force going from the bottom up, not thru it front to back. It's like a empty coke can; it is immensely strong up and down. If you balance right, you can stand on it with one foot. If you do that and tap the other foot on the side of it, it will crumble instantly. It's just the can or part doing the job it was designed to do, then it is strong. Put some other force on it, and it's weak.
  22. fvike

    Fastback inner rockers

    My thinking is opposite. I would prefer the energy to dissipate thru the strongest part - the frame. I would not like the sheetmetal of the roof and floor to handle the impact forces. There is a more direct line thru the car with SFCs, instead of going thru the torque boxes and rockers. But now we're talking head on energy handling, not twisting motion.

    Fastback inner rockers

    That is impressive. My car did not do that. But it's been known for a long time that drag racers prefers the coupe over the fastback due their stronger construction. I'd like to see this on a stock fastback. As an engineer, do you agree with my thinking in the above post? About load paths thru the unibody I mean. It is at least the way I understand what happened to my car in the crash, and my reasoning around it.
  24. fvike

    Fastback inner rockers

    I have to ask; did you replace them due to rust, or due to dis-forming? I studied the damage to my Mustang after my crash, and I studied the load paths the energy of the impact had taken thru the chassis. The crash: rotated into an armco section on the left side of the roadcourse with the passenger side front corner of the car hitting first. Eyewitnesses said the rear of the car was 1 meter off the ground and recoiled back out of the armco. So not the hardest lick, a hit to the driver side front corner would have been much harder. Pictures of the crash damage is in my build thread. The damage: Pass side framerail bent, radiator support bent, top of cowl on both sides bent (which is why I installed Boss 429-style supports after). The top radiator support was twisted. That means the load path went thru the frame rails and back, and thru the shock tower, thru the export brace and bent both corners of the cowl. Everything in front of the firewall needed to be replaced. The floor support did not. There was enough "real estate" that direction because of the SFCs to "bleed off" the energy. I can easily believe that without SFCs, the damage to the car would have been greater, because the load path would have ended at the floor support. The energy shockwave of the crash would have nowhere to go. The SFCs made it so that the energy could be taken up by the whole unibody structure, not just the front half. As we know from racing, crash protection is all about dissipating energy. The more structure you have to dissipate that energy into, the lesser impact the energy will have. The stock Mustang unibody is two structures, front and back frame rails. With welded SFCs you have one structure. The floor support is tied to both the transmission tunnel support and the rockers thru the torque box. The front frame rails is cradled by the floor support, and the floor itself boxes them off. I found them undamaged by my crash, and I believe they are stronger than given credit for. EDIT: Or are they made "stronger" by SFCs because crash energy can pass thru them, not end in them? So it is in my opinion wrong to think of the floor support as a weak part - which a U-shaped rail is - but one has to think of it as a whole structure. It is in fact the part that ties the car together. Frame rails, torque boxes and transmission support is tied into it, and SFCs when added. I like this picture, because the different part are in different colors and shades. It shows the frame rails, torque boxes and transmission support tied together by the floor support. Pictures of floor supports and installment of new frame rails.

    I have not tried that. The X-brace is the anchoring point of my torque arm, so It's never been off the car (while driveable). I can do it for you if you find it important that I do, but per now, I do not have the windows in the car. So it will have to wait until I do. My brother's 'cuda can perform the same "3-wheel trick", and it does not have an X-brace. It does have SFCs cut to the underside of the floor, and welded entirely, except for a window to let the parking brake cable pass thru on the driver side. This is the underside of that car.
