what kind of metal should i use, how thick?

Ottoman

1/8" the plate should be thick enough so that it stays rigid and doesn't bend...

stainless steel, alumuminum, or whatever else u can get ur hands on that doesn't rust

VietFC

no... make sure the plate is at least 1/4" thick. You don't want vacuum leaks. I used aluminum, but most people prefer steel ones.

unless your cutting with a plasma cutter i cant see 1/8in being warped enough to leak, i plan on using 1/8in aluminum with alot of RTV

Ottoman

LOL...

yup

I used 1/8th with gasket material and slabbed some RTV on it too

the big plate is the most likely culprit to leak... especially the top left corner... so make sure u get it good

I got mine from this site...

I like them and they're nice cause they come with screws so you can take out the studs.

(they are 1/8th inch, I think 1/4 is overkill)

I made mine with some 1/4'' thick aluminum. With a hacksaw, a drill, and some patience...they actually looked good with no leaks.

1/4" is crazy overkill. I made mine from 3mm (~1/8") aluminium and they sure as hell aren't changing shape in a hurry.

Unless you're obsessed with bling, use aluminium rather than stainless steel. Aluminium is very easy to cut and drill. SS is not...

i just got some galvanized steel from home depot. it was like 30 cents for a square ft.

First i tried using thin sheet steel chopped out of a spare PC case with a hacksaw, but that just flapped wide open under boost, and gave me a vac leak, no matter how much gasket goo i put on it.

After that I used about 5mm thick aluminium plate - had the local sheetmetal workers cut it to the basic shape, then drilled the holes with my drill and rounded off the corners etc. with the dremel.

Sealing it was a bitch - Red RTV silicone was the first thing i tried, but i guess i applied it too sloppily and it leaked after a short drive round town seeing mild boost..

Finally I ended up using black aircraft-gasket goop (liquid), and I also RTVed up the airholes at the top just to be sure. It seems to be sealed quite well now.

Definitely use the thickest metal practical, aluminium seems ok but if you can get it cut neatly thick steel would be even better.

yea 60 stroke is good ****

would a leaky plate cause a car not to start?

If you can't get a flat peice of 3mm aluminium plate to seal properly then you're doing something very wrong. I used nothing more than a thin bead of sealant around the edges and the holes and never had a single problem.
