To vent or not to vent

Quick vent:

Years ago I was stuck in traffic leaving a race in Georgia in my GT-6 when it started overheating. I found that by poping the bonnet and inserting a can of liquid refreshment to hold the rear of the bonnet open the height of the can cooled things off. I would not reccomend this practice at speed! Of course another can helped cool off the driver at the same time.

Hmmmm, that was back in the days when drinkin' and drivin' was an acceptable pratice, right? In fact, in the old days "Don't Drink & Drive" meant you should wait til a stop light before sipping on your beer, because it was too easy to spill some whilst in motion. Today "Don't Drink and Drive" means something different, fortunately. (Remember "One For the Road"? How did I ever manage to survive my youth?!)

Off to the pub!

Another war story. Many years ago, 36 to be exact, while a dental officer in the Army, we all had hot cars and knew how to drive. Back in the day, it was acceptable in the Army to drink and often to excess. Most of my superior officers were alcholics, as was I. Anyway, one day the officer in charge of the motor pool set up a demonstration that has impacted me to this day. (22 years sober) He set up an autocross course on the airfield with pylons laying out a mildly challenging course. We each took our turn through pylons, the object of which was to beat a preset time and knock over no pylons. Piece of cake. I came in second in time in my lumber 454 Vette, beat by a TR4. All twenty of us made it through the course with respectable times, and no one knocked over a pylon. How hard could this be, we thought? Enter the alcohol. The OIC gave us each a nice cold 12 oz can of beer to enjoy. One beer. We waited 20 minutes and were instructed to repeat out driving feats, maybe even better our times. Every one of us took out every pylon! True story. One for the road indeed.

Thanks, those vents by revington are just the thing I was looking to start with. As for what it entails, you must cut the inner and outer fender, in the same spots and then attach the vent and channel (area that connects the two fenders together), via welding or some other method. You will also need to roll the lip of the cutout area on the outer fender, or bondo the joint to have it look nice and not a raw cut edge.

Or at least this is what I have planned to do.

Would any of these vents work by just cutting a hole in the fender. I don't want to do any metal work since I just painted my fenders, but I think the vents would be a real good idea on my car. Thanks Ed

Hi Ed,

If you mean will there be any welding? Probably minimal, possibly none if rivets or screws were used. Or, is there panel beating involved? Probably. Most vents need some shaping done on the fender. At least, I'd expect the edge of the opening should be flanged inward. Overall, done right, I would think in most cases there would at least be some paint repair in the immediate area.

An alternative might be some sort of flush mounting vents that are self-rimmed. GT6 used these in several places (Spitfire, I dunno). Many other cars did too. I tried a set of Camaro Z28 fender vents, but they are too big and have too much curvature to use on TR4.

There are cheesy plastic fender vents available on eBay, sort of a BMW style. I'm not to enthused about them personally, but they are also self-rimming and attach with double-sided tape.
 
Will these be just for the engine area or will the wheel and braking area benefit too?

Just for the engine unless I want to do some creative ducting and then I think positive pressure from the front of the vehicle would work better, rather than trying to draw anything.
 
with those wheels, definitely vent. i am not a silver fan and since you are changing colours anyways, i like the wedgewood blue with silver stripes that came on the tr250. my car is originally brg with red interior,white piping,white dash,white top which is not seen too much so i am going for the stock (almost-paint and interior) appearing (widened steel wheels with hub caps) but heavily modified 1962 tr4.(white roll bar)
i think those wheels would go great with wedgewood blue.
