Will the 87/88 bumper fit under the 83-86 cover?
It's a totally differant shape? I wouldn't think so. Do you need an 83-86 bumper? I have several
Looking to trim some weight without impacting (nyuk nyuk) safety. I blame fordguy545 and gumby for this thread.
After seeing fordguy545's trimmed bumper, it got me to thinking about using pre-preg CF *as a reinforcement. Trim a factory metal (or fiberglass) bumper of as much material possible, lay the pre-preg, bag and cure it.

If you are gonna be tpuppies it, and already planning to lay the pre-preg CF, I'm sure you could make the 87-88 bumper fit nicely inside the early cover. :evilgrin:
The 87-88 bumper would make a much lighter base to begin with, and likely a fairly easy substrate to bond the CF onto.
I already have a few guys who blame me for certain car hobby related choices they have made; get in line :nkhk:
I was considering a CF or fiberglass hood but don't see that as a viable choice now.
fordguy545 shed a few pounds by removing part of the underside support frame of the hood and trunk. Would a sheet of pre-preg laid on the underside restore the some or all of the stiffness? It would be easy to prep the surface then bag and cure it.
Workin from what I see on our racecars that have CF bodies, rather than adding thickness to the entire panel for rigidity there are patches added only to the specific areas that require it. I would assume the same would hold true on the underside of a sheet metal hood to some extent.
Bumper question - are the bumpers straight bolt-in swaps with regard to mounting (not counting bumper cover)?
Lid questions - I ASSume the loss of rigidity is torsional and not surface deflection? If one were to chop the underside like 545 did, then lay a sheet of CF everywhere there wasn't the reinforcement, would that work like the mods on the race cars? Or would a third layer of another material need to be added, eg foam core?
SWAG ahead:
I would say a web of CF strips bonded directly to the hood, and located where you remove the reinforcements, would make a significant decrease in flimsiness.
Additionally, If you cut some 1" foam in the same layout and bonded that to the hood like a hat channel(similar to uni-body channels), you would add a large amount of beam height which would add to torsional rigidity.
Gumby, not sure I know what you mean. Are you suggesting cutting foam pieces to fit so that the CF has a relatively smooth flat shape?
Basically you would use the foam to replicate the layout of the braces that are cut out, then lay the CF sheets over that. x's are foam:

ah, got it, thx.

Yes, it has begun.
but it's classic dirt
Something besides weight loss?
Thishiznit the floor as the rear bumper came off the car.
Was Ford using punch cards at the time?
sweet, I'm watchin!
I got one off the vert bumper too
Weighed the bumpers. Not including bumper bolts or body mount nuts, the front w/ turn signal was 35lb, rear was 30lb.
The tentative plan is to take a hole saw to anywhere there's space, wrap with pre-preg, then fill with expanding foam. UNLESS >> the 87/88 bumpers can be made to work. I'm mostly concerned about fog light and turn signal mounts. Of course the shape could be an issue too.
Any thoughts?
Was there anything legible on it? Mine doesn't seem to have anything but dirt.

I doubt you are gonna find anyone who has tried it. Guinea pig?
Well, I wouldn't have any idea what that's like :punchballs:
In any case, I'm not
planning on conducting any crash tests.
Does all pre-preg need baking? I thought there was at least one version that didn't require heat, only bagging. Just found something that implies that an oven is necessary regardless.
i got a nice hood from the guys at http://critesperformanceparts.com/ i have their ram air hood on my tbird now and i love it (http://i270.photobucket.com/albums/jj97/ShannunP/img114.jpg)
the guys at http://critesperformanceparts.com/ have a few hoods you may like ... i have their custom ram air hood on my tbird now and it gives it an intresting look (http://i270.photobucket.com/albums/jj97/ShannunP/img114.jpg)
http://critesperformanceparts.com/ has a few fiberglass hoods i have their "custom ram air" hood on my bird and i like it (http://i270.photobucket.com/albums/jj97/ShannunP/img114.jpg)
god thats an ugly hood!
T3 - as far as cutting stuff out of the hood, I probably wouldn't do it again because it is seriously flimsy for the lousy 6#'s I got out of it. The trunk lid however is still pretty stiff and that got 4#'s taken out of it.
lol to each his or her own i guess
just trying to give the guy options...and nice troll btw i guess ya find them everywhere :shakehead
Is this photoshopped?
If it's real, it would make a great gun port for a Mad Max remake with TCs. "Last of the interceptor turbos, be a shame to
blaw it up."
Too bad we aren't closer. I have some 87-88 bumpers you could experiment with. If you need some pictures of them, let me know.
fordguy is
far from a troll around here. You gave an option(however unrelated to the topic it may be), and he gave his opinion; it is what it is.
Nope, it is unfortunately real. If you follow the link Shannun posted, there is a shot of the underside which is set up to house a HUGE carb air cleaner.
I'm
still trying to wrap my head around how big that is. Do you look
over it or
through it to drive?
Okay, thanks for the input. I'm going to experiment with some pre-preg on something small and see what happens. 6# off the front is very tempting.
lol you look over it if your tall enough
The way I see it, you better have an engine to back up the hood, lol.
I spoke with 3M/Duramix and they need to know what kind of urethane was used to make the bumper covers. Anybody know?
(I thought they would have that info but apparently not.)
