Yes, but technically backward progress as if I'd just gone this route in the first place I'd have had time to be working on other things over the weekend.

It's just frustrating- it's now a month out from the Challenge and I'm nowhere near where I'd wanted to be with things. And I have almost no enthusiasm for actually getting stuff done, either- and probably won't for a few more weeks- but there's a lot of things (like everything to be done to repaint it) that cannot be procrastinated on...

Fingertips on my right hand are not happy with me after spending the evening with a razor blade scraping the old baked-on painting tape off the hood and using Good-Off and a scrubber to get the residue off. This evening I hope to sand down the bits of surface rust and rough up the areas that were covered by the tape (they're WAY smoother and shinier than the rest), get it washed off, and hopefully primered. Not delusional enough to think I'll have time to get it masked and the first coats of paint on it, but that would be nice- but likely will have to wait until tomorrow.

What diameter is your exhaust?  If you might need some extra pieces, I could see what I have in my stash before driving down this weekend?

In reply to eastsideTim :

I'll double-check it this evening, but I think that the downpipe from the turbo is 2.5" (though it may be 3"). I'm still debating exactly what I want to do with the exhaust... it's tempting to throw the straight Thrush muffler I have on right after the turbo and set the 'race' exhaust up as the street as well vs. what I had been doing which was to take what I have on now (goes down to like 2" and exits all the way in the rear with a traditional muffler) and putting in an un-muffled setup that exits behind the side skirts (what Shelby apparently did with his own Charger back in the day).

Also- listing to sell the Rampage after the Challenge is now up here (correct link).

I've had (and expect to at the Challenge again this year) a lot of fun with this car, but it will be time to find a new home for it after the competition in a month- I've really got to focus my energy on getting the DMC back in running order.

In my opinion, if the intercooler is already there you might as well leave it. It is true that if it wasn't blowing up without an intercooler and you then install one and change nothing else,  the improvement will be marginal. But, the computer being able to adjust things isn't the real benefit of the intercooler. The intercooler simply allows you to run more boost before hitting the magic temperature in the combustion chamber where the fuel will light off from pressure spikes alone (detonation). The computer will adjust fuel primarily based on boost level and only marginally based on intake temp. A lot of people with turbo dodges have made a lot of power without the computer doing much via the charge temp sensor, or without even having one.  Now, you do have to upgrade the map sensor and rescale the computer to match if you want the computer to calculate correct fueling for any boost level over 14psi. However, even having said that, lots of people including myself have run well beyond 15psi by kludging the fueling to be 'close enough' in other ways. The turbo on the Rampage will max out at 230hp anyway which is ~18-20psi on a stock engine. I maxed it out on my van and went ~97mph in the 1/4 in a 3000lb brick. The Rampage would probably do ~101-102 with the same power. To do that you definitely need a good intercooler and high fuel octane because the turbo is practically a blow torch at that boost level. My van had a crappy intercooler and 93 in it when i ran it at the challenge. I was seeing knock sensor activity at ~13psi (i have higher compression pistons than you too) so i stopped there and ran 14.5 1/4. Van ran a best of 14.06 @20psi  on race fuel elsewhere, and i've also run it on e85.

Anyway, intercooler is necessary if you want to push the setup or go really fast. Not necessary for stock boost. If it's on there i would leave it. Even if you do decide to try and make more horsepower, i wouldn't let the lack of a charge temp sensor stop you. It's just one factor, not a dealbreaker.

The plan is that unless I really run into any problems with it I'm going to leave the intercooler on it. It's already there, so as long as I'm not seeing it be a detriment I'll keep it.

Haven't been keeping up with posting, but have been consistently working on things on the truck. Tracked down some scrap tractor-trailer coolant hoses that will hopefully work to tighten up the intercooler piping and am going to play with adding in a BOV to the system (testing & setting that with air the compressor should be fun).

Paint test on the hood went pretty well- I learned a good bit and though I need to go back and put another coat (at least) of both colors on it before putting on a clear I'm quite happy with how it looks overall. Does give me an indication that it's going to take more paint than I'd figured on, but it shouldn't be a problem- I am planning on not painting the bed with the body color and just using truck bed liner for it though, will save time and money.

Have gotten started on the body work to fix the rust on the body. I'd LIKE to be able to go in and lose all of the previous Bondo work on the driver's side, but honestly that looks like it would be far more extensive of a job than I'm going to have time for (and likely the skill for...) so I'm just going to try and clean it up a bit before priming and painting. I'd also like to be able to make some fender flares to fit the wide AX wheels (and cover some rust & body work), but I doubt I'll be able to pull that off.

I do need to figure out trying to create extensions for the lower Shelby trim- it's too short for the Rampage (being from, I believe, a Charger which has a shorter center body section), and to do the exhaust exit I want to I'm going to have to trim the existing one a bit on the driver's side. May see if I can make a decent-looking framework for it with sheet metal and then final shape with bondo... alternative is to try and make a mold of the existing ones and lay it up with fiberglass.

In reply to Ashyukun (Robert) :

The Shelby Charger that Carroll had used a fake exhaust tip on the passenger side.  Might make thing easier/faster, especially considering the time left before the event.

There were factory side skirts for the Rampage that are the proper length, but they are rare.

Some have cut apart two sets of Charger based ones to make one set of Rampage ones.

In reply to Stefan :

I'm debating whether to have the fake one on the passenger side or just complete out the skirt- will figure it out at some point. If I could find another Charger set that would be easiest by far- but that's unlikely (about as likely as finding Rampage ones...) though I will be doing a quick scan of nearby yards, but 80's Dodges are pretty rare around here...

So despite not having a huge amount of time yesterday I got a surprising amount actually done.

I re-masked off the the inner (silver) portion of the hood to give the outer (teal) portions a few more light coats of paint, and it seems like that was what it needed- I won't know for certain until I get it out in the sunlight this afternoon but it looked much better under all of the light that I had available. Will hopefully do the opposite and lay down a few more coats of silver this evening and pick up some clear when I'm out grabbing dinner so the hood will be finished aside for the (hopefully- it's again supposed to rain...) autocross on Sunday. Only thing to do after that will be the vinyl lettering for the 'turbo hump', which if I'm ahead of the game enough this weekend I may swing by the Makerspace to try and take care of.

Am largely done with rust removal around the body- next step is going to be a bit more sanding and then bondo. I think that's the state it will be in on Sunday for the AX since once it's masked off for priming I don't want to have to take the masking off until I've got the primary color coat down, so the plan will be to try and knock masking, priming, and basecoat painting out next week before eastsideTim will be coming down the following weekend.

Didn't just get body stuff done either- I finally got around to replacing the broken temp sender so I should now have a working temperature gauge on the dash. Unfortunately doing so required taking the cover off the dash and while extracting the old gauge I broke off the needle tip of the speedo (again)- so had to waste a good bit of time sitting there trying to hold as still as possible supergluing the tip back on. Also put the tach into its gauge pod on the dash- unfortunately I don't think that the double-stick tape that came with it really stuck very well, so I'm going to have to grab some more serious 3M double-stick to get it to stay attached. Also finally pulled out the wiring from the aborted battery relocation- need to remember to pick up a new battery tiedown since the rubber piece on the one from last year broke.

And, just checked and the BOV is out for delivery today so I can hopefully get the IC piping back together tonight as well.

So more progress yesterday. Got a few more coats of paint on the silver center part of the hood and it definitely looks better. Not perfect.. unfortunately the metallic paint is a LOT more touchy and difficult to not get 'lines' from the spray pattern- but it has a lot better coverage now. Picked up the clear yesterday so plan on putting those coats on it this afternoon so it'll be totally done and ready to put back on the car (at least temporarily) for the AX on Sunday.

The BOV did come in, so I got to getting it and the new hoses installed on the IC system. Overall it looks like it should work out pretty well- the BOV may not be completely necessary, but the pipe it mounts on helps a good bit in completing the piping system. Unfortunately, the BOV itself is still not completely mounted- you see, the bolts that they included to bolt it to the pipe adapter are not long enough- even without the gasket. So I had to swing by Lowe's when I was out yesterday and pick up bolts that are long enough (but not too long, since they have to fit between the flange and pipe too) to mount it.

Today I hope to get started on the bondo on the body- filling in the rusted-out portions and smoothing out the badly pocked plastic front bumper.

I had been planning on going up to Cinci to hit one or more of the junkyards either tomorrow or Saturday morning, but I'm a bit on the fence about it now as I'm not wholly sure it will be worth the time. I think I'm at least pushing it back to Saturday so I can do some test-fitting with the exhaust and see what I can figure out with it and with the side skirts to see whether it's really worth going.
