Spec Boxster Build

[cmacduff]

A hole was cut in the middle of the trunk and a custom scoop made to funnel air in to it. We did testing on the air flow by taping the strands of a mop from the back of the car over the inlet for the air cooler before making the scoop and used a go-pro to film the strands and see where the air flow was at race speeds. The cooler fan actually did suck the air in without the scoop so we tested some sessions with a "sample scoop" made out of an in box that you would see in an office on the wall. We used double sided tape and zip tied it through the mesh in the oil cooler in let. Temperatures were improved by 10 degrees with the scoop so even though air flowed without it was improved with the scoop. I'll post some pictures of that and also some screen shots of the temperature differences.

Cool, glad to see you did some testing.

I'm assuming when you say trunk -- in this case you mean trunk lid?
Definitely like to see the pix --

I was thinking something similar -- probably looks something like a 930 intercooler.

This mod is not going to be spec box legal, otherwise everyone would be cutting holes in their trunks for weight saving. I would talk to your local scrutes about how (if) you can get air in to the trunk and comply with the rules.

I thought that I had mentioned in an earlier post that this mod isn't BSR/SPB legal. If not, sorry.

Chris' Boxster is an S-model anyway, so he runs in the GT class where mods like this are allowed.

With that being said, you have to admit that his approach to engine cooling is serious!
