Can't say I'm a fan of the colors in respect to each other, but as a whole those turned out pretty boss. are you gonna do one color a side, or one color front, one color back?

I used Meguiars Plast-X on mine (no sanding beforehand) for similar results.

I think with respect to the colors they would look awesome with the center caps blacked out plasti, and then when it dried, cut out the Acura "A"s with an exacto.

Curbed one of my nice wheels on my way to my house to take them off and store until next summer. I haven't curbed a wheel in 16 years. Goddammit.

Driver's seat belt retractor decided to stop retracting and just un-spooled entirely. Looks like I now have a more practical and urgent reason to tear apart the interior once the new assembly comes in from GM. I'm still waiting to hear how long that's going to take, and in the meantime pray I don't get in a wreck.

Had the windshield replaced, swapped the brake fluid, found a leak between the MC/Booster, ripped off rusted out heat shield, Sun of A Gun'd and thought about greasing zerks on my '84 F150. I always fall for the Sun of A Gun trap. Now it looks like i made my door skins out of a the hide of a red/pink piebald pony.

Changed the trans fluid in the car. Dipped the towel at the top in the old fluid, bottom in the new.  I was going to flush out the old rusty coolant too, but I don't know where the drain bolt the chilton book refers to is at on the engine block.

After last weeks wake up call at the mechanics that my car was not so mechanically sound, I Had a friend murder-out my new intercooler. It's getting installed today with a new blow off valve and injectors and a dyno tune for reals now. Maybe I should make my own thread. It'd be nice to have a log of my terrible spending habits.

Geirskogul posted:Sounds like somebody needs a lesson in black-body thermodynamics. Black paint = A-OK. Sounds like someone forgot that intercoolers cool by convection, not radiation. A black intercooler will radiate about twice as well as an unpainted one, but will transfer heat to the air flowing over it (and thus out of the air flowing through it) about 3% less effectively, due to the insulating effect of the paint. There's a reason intercoolers (and radiators, and condensers, and evaporators, etc.) aren't painted from the factory; if the could get extra effectiveness for a couple cents of paint you bet your rear end they'd do it. E: that said, on all but the most maxed-out turbo cars it probably won't make a noticeable difference in output.

Wait so why are all the radiators on my car black from the factory? (not wanting to start an argument, just curious). Edit: After some searching, it looks like the later years got unpainted radiators. Maybe they mythbusted themselves... Pomp and Circumcized fucked around with this message at 02:05 on Oct 29, 2014 |

EightBit posted:Did you really paint your intercooler? Doesn't seem smart to reduce the rate of heat transfer like that. It slightly reduces convection heat from air flow and greatly improves head exchange with no airflow. it'll probably absorb more heat from the radiator but its also like 4 times the volume of the factory cooler core so its going to give back more than it takes in terms of efficiency. either way it is a 2 light coats of a paint-and-prime mixture purely to make it look factory to avoid detection. I would love to leave it bare but police would immediately pull me over and ask to pop the hood and check out the hole in the battery tray (which in my state is a vehicle defect as you're cutting the chassis) EDIT: yes MCM are 'wrong' in that adding black paint does not improve your cooling, but what I took away from their video is that there is little to no loss in painting it black, and for a street car it is more valuable than the 3% of efficiency ever will be. I also did a track day with Marty and the Turbo MX-5 and hes a pretty cool guy

I was about to come in here and complain about their methods, I'd assume that intercoolers get a bit more airflow than that; not to mention quite a bit hotter. Radiational cooling is a thing, but I'm willing to bet that the amount of radiative cooling possible at the heat ranges they run just isn't much compared to dumping it to air.

Yeah, annd being inches from a radiator and AC condenser wont help either. Their point is, and its their fault for not really making it, is that painting your cooler black to hide it/for looks isnt going to have any major impact on its efficiency so if its a make or break situation, you wont lose much painting it.

Over 50% more heat transfer than aluminium, 398 W/m/°C vs 237. gently caress copper, shits weak. Use silver (about 7% better than copper and 81% better than aluminum) instead  Fun fact - some of the transformers at an aluminum plant on Long Island in the early 40s were made from coin silver "borrowed" from the treasury because the aluminum was more critical for the war effort and we were running short on copper. Apparently some of it made it into transformers that powered the Oak Ridge uranium refining plant necessary to build the bombs, too. Or diamond, if you could find a way to make an intercooler from it and keep it from breaking, diamond's thermal conductivity is about the highest of any known substance at 2200 W/m/°C.

It'll be dyno tuned today so I will post the graph. Not that it will prove anything since I also had a bunch of other poo poo done and didn't test it before it was painted but whatever.

So 6 years of owning the thing and I finally got off my rear end and had a dyno tune done. High boost revealed a lovely dying clutch that slips. This is problematic but not unforeseen as its been on there since I bought the car and I can only assume a decent while before I owned it too. Overall I am happy with the results and the tuner tells me there is enough headroom to get to 200kW at the wheels if I can handle running no catalytic converter.

ShittyPostmakerPro posted:Wait so why are all the radiators on my car black from the factory? (not wanting to start an argument, just curious). Well, on older cars the radiators are copper/brass. The paint keeps them from oxidizing. The only reason to paint aluminum radiators is to keep them from glistening through grillwork I suppose.
