Bonnet vent/scoop/buldge....??? opinions please

Very difficult to acheive, as the filler is always going to crack due to heat from the engine onto the bonnet, and moreso from the bonnet flexing and being opened and closed. My guess is it would look very good for a few days, then the problems would set in, weather, damp, etc would all find their way under the cracked paint and well, we all know where it leads from there. Afew of us looked into making the visteon scoop functional rather than simply decorative, but really it wasn't worth the hassle. For a genuine scoop/vent, i would go for the "S" style, but even this requires major butchery below the surface as the cut lands right over the bonnet bracings.
Think I prefer the bigger one actually, more agressive to suit the new engine!
no problems mate, not perfect but was my pleasure
Yup, I'm with you on this one Alex, think the second one does look the business and definitely makes the whole front end look more agressive. But it's down to individual taste Gav and what you like, don't listen to us lot. you have to be happy with it, not us.
roughly £700 to import the kaminari hood, and they are made to order. Mine took about 7 months from ordering to receiving
Like Rich B's bonnet is what I ment, the main heat source being the front of the engine were the exhaust is and the side where the belts are. Figure if you have vents on the right side (looking at bonnet from the front) you run the risk of water in the electrics, battery etc. And at rear the coil pack gets wet. Although the right side is were the airbox is too so you might want a vent for that
if you're gonna smooth the visteon scoop on use fibreglass resin and matting to bond it ! done properly it shouldn't crack, i.e. bare metal the area you're going to bond to, use as little filler as possible, cos it's the filler that will crack ! might do it to mine seeing as the scoop never sold !
This is what I was thinking, if done properly then it should be fine. It was just a thought though. Other than that there is a company called Cool Louvers who do this kind of work to bonnets. Might be worth a try with them but I think it will be expensive.
Think about airflow before you go bolting functional scoops to the bonnet Gav :stop:
When moving you have air entering the front of the engine bay through the grill, if you add a ram air effect at the back you might end up doing more harm than good, the positive pressure will have to escape somewhere
My instinct would be to fit louvres which will allow the cool air entering the front to push across the engine and out through the louvres taking the heat with it
Just a thought, Jamie will probably elaborate on the rights and wrongs and explain the theory in terms us mere mortals can understand
Oh yeah, I like em both and Al`s - Ace`s idea

I checked them out Kool Louvres as they are called, looked like the website hadn't been updated since about 2003, so not even sure if they still exist? They press the louvres into the sheet metal at a price of about £10 a louvre or near enough, but you have to strip the top coat of paint off iirc.
The idea is you have a vent or louvre this disrupts the air-flow over the bonnet, causing a low pressure area which then sucks the air out the vent.....see Jamie isn't the only one who can talk the talk
