Evening all

i have just been looking at the carbon mods website and my wallet started shouting at me, NO NO NO NO NO NO, so whilst browsing i came across this

carbon mods page

i dont have a bonnet scoop on my car but have been thinking about getting one for a while as i have a burton racing rocker cover but it doesn't fit under my bonnet without a scoop. then it got me thinking,

how would you go about fitting a scoop onto a bonnet that doesn't have one?

obviously there would be cutting involved but how do you fix the scoop to the bonnet..

"The scoop needs to be securely installed and is provided complete with a paper drilling template and pre-bonded fasteners to ensure trouble-free secure installation", maybe?

Depending on how it is underneath, you could use PU adhesive and/or rivets from underneath

I think you'd be safe just bonding it on.

Obviously observing the normal rules re bonding ie Keying the surface and clean/dry etc.

By the way, I saw the bonnet bulge for the first time yesterday and it's a really high quality item! Made me want one and I don't even need a bulge!!!

They often have a small "return" on the inside of the scoop around the edges.

I just cut the bonnet hole so it was the same size as the scoop and rivetted through the bonnet and scoop....

i think that rivets would be the best way to go, the last thing i want to see is my bonnet scoop flying off at 70+ mph (on the track of course)

I fitted a GRP scoop to the bonnet of my turbo'd Corolla in my youth. Quite wide opening and directly in the airflow. I used 6 bolts through the flange inside the scoop. Unfortunately at 135MPH the scoop separated from the flange!!

The next one was glassed up twice as thick and had 8 bolts holding it on

my Cortina’s scoop (originally stared as a small bump to clear the carbs) was hammered out from underneath with a ball hammer and an friend holding a block of wood on the other side 'imperfections' were removed with body filler and a grinder cut the slot. Worked really well.

A word of warning - This is probably better suited to metal bonnets than fibreglass ones!
