I used a similar setup in my 944 race cars, the cowl induction is fantastic, lots of air. Just remember to cover it when it's raining!

Just as an FYI, that modification is not allowed in PCA SPB racing. I wanted to do the mod when I built may car and had a long discussion with Walt F. at PCA. Below is part of an email response to me.

"Tim - none of my rules committee colleagues are in favor of allowing any openings in this cowl/battery tray area to be used for cabin ventilation if the stock components are removed. I don't doubt that having these openings will move air into the cabin, but there are other ways to get it."

To get around this, you could easily make a plate to cover the openings when racing with PCA. Again from Walt:

"So your removable plate sounds like the way to go."
