KNIGHTSPORTS VENTED HOOD INSTALLATION
The Hood Arrives


The new hood to be installed.

And so it arrived.... wrapped fairly well with plenty of padding. When delivered I was informed of a damage to one corner. Ok it was agreed we would knock $50 off the price. I took the wrapped hood home and there it sat in my garage for 3 months while I tended to other car matters and could find the courage to begin the installation process. Three months pass and I'm ready to head to the track in the middle of August. It's going to be a scorcher. No better time than the present to stick on the vented hood. Turns out to have been a good decision. It was 105 deg. F at the track at 5pm...who knows what it was at noon! In any case I gingerly unwrapped the entire hood and gave it a good look over. For anyone undertaking such a project be forewarned most if not all after market body parts will require finishing before paint can be applied. In my case it was porosity in the gel coat, the broken/cracked corners (when unwrapping the hood I discovered another damaged corner - DAMN!), rough unfinished seams on the underside and poor application of the gel coat around edges, particularly the vent openings.

The second UNDISCLOSED broken corner.

Porosity in the gel coat.


Rough material along the edges and flashing material around the vent opening. This was common to all the openings.

Unfinished vent opening illustrating how the two hood halves are bonded together. Note also the indents where the rain guard mounting hardware holes are to be drilled. 

Another vent opening. The seams were pretty raw and needed quite a bit of
finish work.
I was not disappointed, as I got a good price, but I wasn't ecstatic either. It was going to require quite a bit of finishing work, unfortunately more work than I had time to handle myself.
Initial Fitment

The first thing to do, obviously, is to remove the stock hood. It is amazing light [made from aluminum] and probably the reason it dents so easily. With the stock hood off the new hood is bolted on. Pettit's hood comes with an OE style latch and hardware for mounting to the hood hinges. With the hood bolted on I held my breath and tried to close the hood. HA! Not a chance.


First things first - off with the stock hood!


As closed as it was going to get without some "adjustment" of other under hood components. 
It seems all the after market stuff I had under the hood was creating quite a few clearance issues. To be specific I had to lower the oil catch can but 1/8 inch [no biggie just elongate the mounting holes in the bracket I made], drop the battery fuse/relay box 1/8 inch, and the biggie was figuring out how to get the hood to clear the CWR intercooler and intake box. I had a choice, hack the hood or hack the offending component. With the airbox the choice was to cut the box. I had made my own intake box cover anyway so the box was notched and a new cover fabricated to clear the hood. As for the intercooler this was another story. The intercooler was situated as low in the engine bay as it would go so I had no choice but to notch the hood. With great trepidation I began sanding/cutting away the underside of the hood ribbing that was hitting the top of the intercooler. I removed just enough material so I could now get the hood to close. YEAH! It still rubbed but the hood would close. Good enough for the track but it would require more work.

Interference issues with the CWR intake box. Note also the delamination of the
gelcoat around the vent opening.

The new "lower" profile cold air intake box cover.

Just to be sure the hood wasn't going to pop open I also installed hood pins. I wanted hood pins but not those huge pins requiring big loops and cables. Something that would work but wouldn't be so obvious. Moroso had such a pin. The outer rubber hood supports provide the perfect location. With these removed the pins were bolted in their place and I removed the clip in the bottom of the stock rubber bump stop drilled a hole through the middle of it and slid it over the pin. The hood holes were drilled and the clips riveted in place. But be sure the "measure twice and cut once." The last thing you want to do is drill a hole in the wrong place!

Hood pin and rubber bumper location in the engine bay.
One thing I was amazed at is how large the vents look when the hood was actually on the car. That and the fact that their locations lined up with the flow paths I had envisioned. The thought of fabricating a duct to route air from the rear of the IC straight out the hood vents had even crossed my mind. Maybe someday.

Huge vent openings. Mesh definitely needed to avoid errant hands from
fiddling with my AST cap! 

Note the good flow path straight through the intercooler.

As for the overall fitment of the hood I was very pleased. The hood lined up very well, gaps were essentially identical to the stock hood and it looked to me like a good fit. And with that I headed to the track with my unpainted hood
