Give Nabbott a shout - he's experimented with reducing cockpit temps

Other Abbott is correct - I've done some experimentation in this area with good results.

Whilst driving the car I was finding that the warm air was being pulled into the cab with the vortex that the 'aero screen' produces - this would increase under braking! My rear clam has a large (and rather unsightly) hole cut into it to accommodate my kinsler injection system - thus blanking off the aperture isn't an option. I did however have great success with installing a Perspex (5mm) air dam - with holes for airflow - on the back of the rollbar. This has all but eliminated the issue!

I blanked mine off with a piece of carbon. It had an effect but not a massive one. What would sort it would be a way to create negative pressure in the engine bay by sucking enough air out at the back to make the pressure in the engine bay lower than in the vortex behind the windscreen. Suggestions from aero bods welcome!
I have seen an ther canam with a perspex screen in the roll hoop a good few years ago at lemans.
I am about to fit an Inglese inlet system and would disagree with the unsightly comment.

Here's the dam I made up. I experimented first with a piece of MDF - whilst it solved the heat flow issue - you were unable to drive the car much past 70 (ahem!) with the buffeting!

The configuration of holes keeps the flow through the cabin, so there's limited buffeting:

You can see I've used some thick draft excluder on the bottom as I was finding that the air was still being pulled into the car!



If it's too hot after you've done this I'd also fit fresh air vents (done this mod as well).

Post resurrection. Did the Perspex wind defector work ?
I can confirm that after picking up my canam up last Sunday and driving 180 odd miles. It's very warm in the cabin.
Could wear shorts and t shirt in the winter months !

What do you tink about a vortex reduction slot?
Something like what all the rest of the world make on spot bikes?

I just blocked my vent to stop the backwash, made no real difference in performance, kept me cooler though, and a bit quieter.
