  • newbie Q: FG engine bay

    just wondering, am i able to make a fibreglass cover to sit on the engine, IE: engine rocker cover, just to make it look more aesthetically pleasing.

    or would it melt, or is there another method i should use


    Regards TC

    fiberglass hoods are everywhere these days... but as for something directly on the engine, the risk of fire is too great for me to ever attempt it.

    a metal pannel with heat resistant paint might be a good idea.

      this has been done before many times on a showcar as well as regularly driven vehicles. No chance of it catching on fire barred you didnt do something really erratic

            he said the RISK, not the 100% chance that it'll happen

            lol, i wouldnt put anything directly on the engine, just because it wont let as much ventilation..

            haha

                my fuel rail covers are plastic. i have headers and internal mods to the engine...never had even a sag. the covers are also painted and clear coated...no problems there either.

                  You might check that out.

                  I think if you bend a sheet metal heat reflector to cover the area that your cosmetic rocker cover might be exposed to and then attach the cosmetic cover to it you'd be in good shape. Just think of ways to dissipate and reflect the heat away from the laminate.

                  Also take a good hard look at the MSDS for whichever resin system you decide to use. That should give you some degree of flammability information that you can use to decide if you're safe or not.

                  it might be worth mentioning that heat resistant ABS (which is what most engine compartment plastics are) or in some cases HDPE have melting points of over 240F. Use that as a guideline. Also look at www.matweb.com, they might have your particular brand of resin or plastic listed there along with it's properties.

                  In any case it sounds like an interesting project. Will you keep us posted as to what you decide to do or any progress you make?

                    My plastic intake tube is right above my turbo manifold. That's all integral to my plastic engine cover/air filter box.

                      does anyone know the heat tolerances for Fibreglass anyway?

                      i could never find any..

                      but like others have said, it catching fire, probably not, theres hundreds of plastic parts in the engine bay, and many others have put fibreglass pieces..

                      i just want my ventilation dammit!, lol

                      but yeah, if anyone can point out the tolerances for fibreglass that'd be great

                          does anyone actually read the posts, or is there just an echo in here?

                              Do you mean an engine cover like what you'd find on newer cars (Audi, Mazda, etc etc).

                              The one in my mazda just looks like basic plastic, I don't see why it wouldn't work. Maybe the thermal properties of FG is significantly different than that plastic, but it's worth a shot.

                              Try mounting it so the FG isn't physically touching anything hot, and maybe use some tin foil to reflect some heat away from it.

                              The McLaren F1 uses solid gold foil to reflect the heat off it's carbon fiber panels, but then again, that's a 6064cc V12 (aluminum alloy block and head no less)
