Hi all,
Before starting to cut metal, I'm looking for feedback about installing fender vents in a TR4 and would really appreciate comments from anyone whose done this.
Specifically, I'm considering doing something a bit different from the usual triangular "Shell Rally" vents right behind the wheel arch. Looking at the body work, it appears it would be relatively simple to install vents above the footwell and might give even better air exhaust from the engine compartment because it's higher and further rearward. I.e., the proposed vents would right next to the wiper motor on the LH/driver's side and would require moving the voltage regulator on the other side (which is gone from my car anyway, after an alternator conversion.)
From photos I've seen, it appears the Lemans TRS cars had an underhood vent arrangement something like what I propose doing.
There is a flange on the inner fender that would be ideal to tack weld in a "floor" for the vent. The baffle behind the front wheel would act as the forward "wall. A rear "wall" would need to be fabricated. Rubber strips such as are original on the baffle would be used to seal the vent to the outer fender.
I've figured out a way to use simple expanded steel to form a grill work on the fender. My main concerns are that cutting openings in these areas of the inner fender might effect body integrety, the area between the inner and outer fender will be odd shaped and that the "floor" of the vent will slope downward. Am I just over-engineering this? :rolleyes
Any other considerations? I'd be interested to hear everyone's thoughts. Quick, before I get out the nibbler!
There is a photo showing a mockup at https://www.triumphowners.com/640, in the "Bodywork" photo album.
