I just recently bought this over E-bay... http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2488974528&ssPageName=ADME:B:EOAB:US:6

Now, he had a breather filter installed on the oil filler tube, (no oil cap obviously) and had the hose that came off the throttle body removed and capped off. The hose that came off the oil filler tube is now routed to vent outside through the bottom. So, ok I figured I would replace that and put it back to like it should be, I reinstalled the oil cap and ran the hose from the filler tube to the throttle body. Well, I went out and roadtested it and WOW, I thought I blew the motor. TONS of smoke came out under hard accel though the exhaust and it actually blew the PCV out of its place. To much blow-by gasses I guess. Keep in mind the car does have a 10 PSI supercharger. I restored all the hoses like he had it and the car actually runs fine, but I am still worried.

I am now actually going to tear the engine apart and replace alot of components. JE Pistons, comp 9.0:1. 0 gap rings, Eagle rods, new bearing kit, all new bolts (main cap, crank, etc) and camshaft. both front and rear seals where leaking aswell as the pan, so ofcourse that will get fixed. Anyone have other opinions on what to look for to fix? This will be my first 5.0 I am going to tear down and rebuild.

The car came with a Powerdyne supercharger, which I think I am going to trash and replace with a Procharger or Vortech, the Powerdyne seems to be making some kind of rattle noise internally like bearings are starting to go out.

Anyone have ideas on what cam I should use with a blower aplication? I wont exceed 10 pounds of boost and if you see the link, the car is well equipped in the fuel system department, so I dont think I am going to mess with it.

This is fun though, I had the car for 3 days and already I spent over 1k on stuff for it. It had Mac off road H pipe and flowmasters which I am trashing and have all new Bassani catted X pipe and cat back comming for it, new shifter. I am waiting to tear down the engine to find out if I need to hone the block and maybe order over sized pistons and all that stuff.

Damn I love all the aftermarket stuff available for 5.0's! :nice:

Oh and btw, the car is in AWESOME shape both inside and out, tha paint outside is great! I think I got a good deal!
 
lol sorry dude, but don't you think he had it set up like that for a reason? That hose doesn't go to the throttle body from the oil filler tube to prevent pushing boost into the crankcase. So you're probably right--you probably do have bad seals from all that boost. I see you're new to Stangnet and it's an awesome tool. Research and learn before you do anything major if you don't know about it.

I'd suggest researching about rebuilds if you don't have much experiece with that. A custom cam is definately the way to go. You can contact Ed Curtis at www.flowtechinduction.com for a custom cam, or others make them too - Buddy Rawls, etc. I read that Ed is busy, so don't expect the cam to be delivered the next week or anything. The key will be planning.

They do make rebuild kits for the powerdyne which allows you to replace the bearings and internal belt. I know JadeFalcon has done that and has experience with that, but I haven't seen him around for a while.
 
congrats on the new cobra! looks and sounds pretty sweet. Cool that you are prepared to go thru it and redo the engine soon, as it can only help to make it more reliable. no sense in waiting until something breaks. if you have the cash now, it is definitely a good thing.

I also agree with giving ed a call or an email. he is very good about replying, but as was mentioned above, in the summer he is pretty busy so be prepared to get in line.

Some AFR's would really wake it up too, unless you are trying to keep it with most of the original parts. just depends on what level you want. In fact, since you are planning on spending some cash soon anyway, and thinking of dumping that blower for a better one, it really might not be a bad idea to get a dart block for it, just to be safe. then you will never have to worry about it, no matter what you add or swap.

Would you know who sells the rebuild kits or where I can find them?
 
Please don't replace anything on that powerdyne charger, it's an insult to a beautiful cobra, those chargers are known for ruining bearings. The best powerdyne is not even as good as the worst vortech. If you want to do the car right the first time, just switch to a vortech this way you don't waste any time or money.
 
As far as I know, Powerdyne has solved the short-lived belt and bearing issues. At least that was the consensus a year or so ago. Yeah the Vortech is a better blower, but the Powerdyne is soooo simple, super quiet and doesn't involving tapping into the oil pan. Believe it or not, there are still a few out there who will take a simple, inexpensive, hassle free, user friendly set up over a more involved install and more power. If he’s gonna change the blower, why waste time on the Vortech and go right for a Novi?
