any ideas if it would be better to have a hood scoop facing front or towards the windshield

I think that the lower pressure would be towards the windshield so that hot air can be drawn up from engine bay?? which is what I want to do

i read an article on this the other day and from what i understand youd want the vent placed as far forward as you can. obviuosly rear facing. cant remeber exactly but a guy did some testing with bits of wool stuck all over the hood and got somebody to take a pic while he was driving. he then was able to see roughly how the air moved around on the bonnet. believe it or not he did this test on an alfa gtv 4. shame i cant remeber where i saw it though if i find it i surely will post it up here.

cheers

hmmm i wonder what a double row punched louved chunk of sheetmetal bolted in where the stock plastic on the hood would do for bay temps

Hey Short...that's a great idea...i've been looking for a scoop doggy, when all I need is louvers!!!

kinda like the old jag vents....but in the middle

yeah exactly and if done right it could be something that bolted into the stock location where plastic unit is...if ya find it not working turn it around...if it still dont work ya go back to stock and the hood is never actualy modified

yeah...can't find these anywhere for cheap

Don't laugh, but you might be able to adapt a wall vent from a hardware store. Definitely cheap and probably aluminium so it won't be too heavy. Might not have louvres the full width of the cover but might be able to get one with 2 or 3 sets of louvres that end up the right width.

The 280ZX turbo has two hood vents that fit the GTV6 hood really well. One is a combination NACA style scoop and vent, and the other is just a vent.

i was actualy thinking of what about haveing a custom body shop roll punch some sheetmetal to the right size..should be under 100$ ...or you could buy your own roll punch and do it

unfortunately, 280zx vents are angled....

I did find a scoop the right size from summit..

Louvers are hard in the size I want. louver press dies seem to only be available up to 5 inches and cost 450$

I guess I can buy some thin plate stainless .030in and cut and spot weld my own.....

I am not sure what you mean by angled. The 280ZX Turbos scoups have curvature in them that nearly exactly matches the curvature of the GTV6 hood. I have a pair in my garage and I have checked this out pretty carefully.

i belive i saw a set at eastwood that could do up to any lendgth you wanted

so what scoop ya eyeing at summit?

MD: vents have an angle if looking down from the top....

Short: that's a big catalogue...got a page## or pic??

HUWARF!!! .......thats just nasty lookin...looks like a lund POS non functional unit thats held on by double sided stick tape


not sure how well the curved lines will work on a gtv6 body with the body being so tight/square edged

just type in louver on eastwood's website and you will see alot of them..die's up to 5 inch and roller versions wich can basicaly make a louver any length you want......NOT cheap...thats why i would sugjest contacting some streetrod/body shops and see if you can find someone who can make the louvers on a piece of sheet......being the hood insert is such a small piece i cant see it costing much in louver time from a shop that has the setup to do it
