"FEELING HURTER" Another black '88 XR-7, force fed...

I should really get around to updating my signature LOL.
So finally here's the thread about my recent score from Bahhhston. It's remarkable how rust-free this car is. The inner passenger door bottom is a little crusty but nothing some grinding, a dash of epoxy/mud and paint can't cure. That's it. 170,000 miles. Doors have several annoying dings in them but overall the body is real straight. One dime-sized surface rust spot on the trunklid, and some big paint chips off the front bumper. Carlite glass all around. Has keyless AND moonroof. I was shocked to find that. Unlike the red car, this moonroof seal is actually still supple and puffy and probably doesn't howl like the wind in the beginning of Holy Diver.

You Probably can't see it but that dash is 99% crack-free. I swear that's half the reason I bought the car :hick:. The silly title comes from the things many jackass kids seem to say now about their Mustangs and Camaros and such, as well as the CL ad. Uh no..I think right now ITS feelings are hurting because it's semi-broken!!

So the funny stuff: A fuel pump and lines that can support 1,000 horsepower. "Slightly" built AOD. No beefed up clutches or bands in there unfortunately but a shift kit (I'll probably tweak anyway) good 3k RPM non-lockup converter and 1-piece input shaft are. Was told it slips when warm...lines go to the radiator...195 degree stat. Yeah. Probably overheating constantly. Fluid seems fine, we'll see what happens. Edelbrock performers, cobra intake, F-cam. Hollowed out cats in the 'stang H-pipe. Laughed when I found that. Haven't KNOWN of any car that someone did that to yet. I wondered why it was so loud! And of course, a P600B Procharger. Seems to be fine but I think it's leaking oil from the return fitting. Intercooled, might be the 3-core one from what I've read. It's long and the bumper was..massaged a hair to fit it in there.

So right now I'm working on getting it back together and reconfiguring the piping a little for an SCT-2600 MAF at the cone filter in the driver's fender, and getting some injectors. Had 38's. Mustang Magic down in LI uses SCT and they told me to get that MAF. I have to ask them again about injectors because I'd like to spring for some ID1000's and buy injectors once...;) Obviously I want as much as I can get out of it. Going to have to buy at least a couple pulleys. Dyno tune I don't demand to make more than 400-425 hp, then see if they can set up some safe-bet tune to push the boost and go for closer to 500 at the end of the season. It has a main cap girdle which I read seems to help keep things together when the block splits. I just don't wanna ruin the heads. So we'll see.

Thought it had a blown HG because the radiator was pressurizing quickly and Cyl #1 was not firing. Header was warm/hot but not scalding. Car was mildly backfiring too as it sat there idling. Exhaust smelled normal for an un-catted car. But upon tearing it apart the HG seemed fine. Heads are both flat within .001. I'm thinking dead/plugged injector but why the popping. Car had sat for several years. Pistons all look good and so do the cylinders. I was told and it's quite evident that the motor is barely broken in.

So I'm treading real slow and reading 'til my eyes hurt and talking to people. I'm real excited, this is entirely new territory for me.

The blower is so funny-looking to me. Really "basic" looking and almost 1970s-early-80's looking with the fins. Apparently rated at a max of 60K RPM and able to support 775 horsepower, though I've read that ATI's claims were a bit optimistic. I don't know when it came out but this kit was bought in 1997.

Potential for a great sleeper there.  It would absolutely roast those tires once everything is working as it should!!

Dude should have run a cylinder balance test before tearing it apart ;).

Just because the radiator has pressure doesn't mean the head gasket is shot. It's supposed to have pressure. My Thunderbird is pretty much always pressurized after a drive. The engine never gets above 185*-195* so it never makes enough pressure to pop the pressure relief in the radiator cap. The level in the coolant overflow only goes up about one inch above "Full Cold" when hot :hick:. A blown head gasket will pop the pressure relief valve in the radiator cap, force coolant into the over flow, and then out the overflow onto the ground.

That Cougar appears to be in pretty nice shape. Nice score. So is this one or the other black Cougar going to be running first?

I've never done the cyl balance test on any of 'em. I keep forgetting about that  thing.
I haven't run the car longer than 5 minutes from dead cold at any time. I felt there was a lot of pressure within that time. Definitely would expect it once fully warm.

The 5-speed/Trick Flow black cat is still waiting for front subframe repair. Friend's dad took on basically a full shell resto of a '65 Mustang one year ago and he's rather dragged on it. I'm willing to wait for him though. Literally in the neighborhood and he knows and is OK with how picky I am :D

Looks like a nice project man.  There's something about a black Cougar...
