Struggling with the exhaust. Need help
I've spent three days now trying to design an exhaust system for my car with absolutely no success. Each time I figure out how to clear one item, I get interference with something else. If I try to run under the outriggers or master cylinders I end up with only 1-1/2" of ground clearance.
Did original FIA cars run the pipes in front of the outriggers? I'm about to just give up on this project as I continue to run into obstacles at every point of the build. What started off as a fun build has devolved into a nightmare of continuing obstacles |
I take it you aren't running side pipes?
|
Yes I am. At least trying to
|
Hmm. Well, probably not a lot of help w/o pictures from both cars but, my primary pipes collect in the middle & shoot down between the foot box & inner wheel well. The pipes connect there & make a 90 deg turn underneath the body.

I just cant figure out how to connect the headers to the sidepipes

Bill this pic shows the Daytona type Twin exhaust per side, but if you look closely you can see the two pipes from the tri-y headers under the car going forward to the engine. Only two FIA cars used this system, all others used the single side pipe, but I believe the actual headers were all tri-y configuration. If you intend building tri-y headers there are several Daytona Coupe pics to show the correct pipe sequence, but you will need to design your own to suit your chassis as Daytona engine sits lower & more rearward in the chassis.
Damn, I don't know how the pic ended up being so large, Ive never been able to do that before! PS, bear in mind most original FIA cars actually have quite high ground clearance/ride height |
Thanks J.R.

i don't think that will work. The space is too small for two pipes
|
I cut the merge collector down and cut the primary tubes. Does this look workable?

1. Buy corrugated plastic tubing from the hardware store in the diameter I intended to use. 2. Cap the end off at the head and and then snake it around until I got the fit I wanted. 3. Once I had it, hold in place with tie-wraps and spray expanding foam into the other end. Once the foam sets, my "mock-up" pipe would be non-flexible and I could remove it and have someone make up the real deal. Never tried it but think it would work. Disclaimer: Many things I thought would work have failed miserably :LOL: . |
Looks like it would work.
What does it look like with the pedal assembly in? Quote:

What pedal assy? I can't get Bruce to give me the part numbers.

Original cars had short Belanger headers with collectors very close to the block. Something like these: 1962 1965 Shelby 289 Cobra Road Racing Headers Stainless Steel Repro | eBay
Side pipes looked like these: http://www.clubcobra.com/photopost/data/15/DSC00390.JPG How that would translate to an FFR though, I don't know though. Sorry! Larry |
Thanks Larry. I doubt they would fit my application.

I know it's the last thing you want to do but. You can probably get another inch or so of space if you move that body hanger forward as far as you can. I can try to get a picture of mine later today, if you like? I'm pretty sure there's not a ton of room in my car either. A little more than that, though.

Bill, for what it's worth, this is the setup on CSX2136

These pictures were in my "Kirkham" folder:

Thanks Jim. I've decided to take a break from the build until after the holidays. Too much to do and it's difficult to focus on the problems

If at all possible consider putting your system forward of the brace, then angle the collector towards the position of where you want to come out on the side of the car. I see your present system as building a large heat sink, which will cause you fluid problems with heat build up in the future. The orginial Daytonas had asbestos shields to stop heat from getting to the fluid cylinders.
