That sounds like a good method. Thanks. See if you can get ahold of your friend.

Yep, thats how we did it. Piece of cake to do, and it was 4 1/2" around though I did grind out a hair more so I had abit of play. Heres before and after pictures:
So, basically, the center of the existing hole is the center of the new hole? That should be really easy. I thought that's how it went. Thanks for the pics. I'll post a pic of mine on Monday, after it's cut.

Bottlfed, are you painting the bay afterwards? or cutting the hole with it painted?? I remember you have an incredible engine bay, and If it's already painted I'm not sure if the jig-saw would cause the paint to chip. Just a thought. We painted the bay afterwards obviously so it wasn't a problem, but it's something you might want to watch out for.
i know a super old thread lol but to answer your question it seems it depends on what supercharger you have and where the inlet will sit. With my V3 that I'm about to cut the hole for, the orientation for mine will put the hole closer to the strut tower I'd say from the hole in this pic, probably 2-4 inches to the right....So, basically, the center of the existing hole is the center of the new hole?

LOL I'm sure and I didn't check to see when the last time he was on as I usually do I was just checking something online right quick before I cut my holeDude hasn't been on since 2011.
I'm pretty sure he's moved on.
Huh lol?"quick before I cut my hole"....if you didn't already have a good CT...

yeah I borrowed one from work and at it wasn't super easy but not super hard. At the angle I was cutting at because the side of the wall wasn't flat and had a hump, the bit was long enough to bit and make the hole and the top of the saw blade caught first and it kept stopping some and I had to pull back and let it start slightly before touching the metal. It wasn't so bad and took about 5 mins ish mostly because of those small issues...Hole saws work great if it is a "virgin" hole that you are making. However, using a hole saw in to enlarge an existing hole is very difficult. If you were to fasten a scrap piece of wood or even 1/8" aluminum sheet to the back side of the existing hole, then the wood lets you make a new "pilot bit" hole and keeps the hole saw steady. I have done this on 1970 Mustang headlight bucket "cups". The halogen light upgrade needed bigger holes for the backside of the fixture to sit down into the cup properly. Apparently, this technique works well on thicker metal too like brake backing plates. At ~3:15 into the video, a guy is using a hole saw to enlarge the hole in his backing plate.
Big hole saws tend to cost several dollars, and it is great if you can borrow one as large as 4.5". It looks as though the jigsaw worked well on the thin metal.
