Thanx for the heads-up on this...I just snagged the last one at my local, and I had to dig in a bunch of other models to find it. Remarkably nice little model for ten bucks, though the chassis is typically blodular. There's certainly a nice, crisp bunch of body castings, and plenty to make the basis of a really unique build.

Question on AMT model kits
Ace-Garageguy replied to wheelingmountaineer's topic in Model Building Questions and Answers
Unless you're building exactly stock representations of production vehicles, or replicating a particular vehicle, your imagination is your only limitation. For replica stock builds, google image search is your friend. Look for photos of restored or original vehicles to get a very good indication of what color things should be. -
Old dog struggeling to learn new tricks

Wow ! That Indian gas station is REALLY nice, very believable. Great work. -
What store (I'm also in the Atl. area currently)? Under $10 is about what I can afford this Christmas.

AMT 1932 Ford Hemi Specs
Ace-Garageguy replied to Mr Dedo's topic in Model Building Questions and Answers
Casey's right...it's in the AMT '32 roadster kits. Detail is soggy, but it will pass for a 331, 354 or 392 Chrysler. It's backed up with an old Ford (think '39) 3-speed. There's also one in the Revell 5-window, which will also pass for a 331, 354 or 392 Chrysler. The Revell version has got very nice no-name, polished cast alloy aftermarket valve covers, but the exhaust port spacing is a little wonky for some odd reason (they SHOULD be evenly spaced, and aren't). Induction is dual 4-bbl, and the gearbox is a no-name manual. There is also an early Dodge "Red Ram" hemi in the AMT '29 roadster kits. The Hemi has been in the AMT roadster kits all the way back to 1959, though there are some engine differences in the later releases... -
This old movie has finally made it to youtube in its entirety. Besides some very very nice period hot-rods, the experimental Chrysler Turbine Car is featured prominently. Worth a watch before the copyright police strike. Just look up "The Lively Set 1964" on YT. All kinds of technical errors in the dialog, but kinda fun anyway.

Very attractive model. Did you open the decklid, or does it come open in kit form?

Recomend glue for resin.
Ace-Garageguy replied to om617's topic in Model Building Questions and Answers
So far, this is the best CA glue product I've used on resin, and for bonding various metals to resin and styrene. It also makes a good edge-filler for getting cut panels to fit openings precisely. For ultimate strength, a high-strength epoxy would be better. I put a lot of load on joints while doing heavy mods with a lot of bodywork...that's why I go for strength overkill. -
Yup, and the intercooler-cooled compressed air from the turbo compressors blows into the Roots-type supercharger inlet, and the Roots blower compresses it further, raising the boost. Entirely different plumbing from the red Camaro. Just to clarify for the audience: Turbocharger compressor inlets are facing the camera. Turbo compressor outlets blow into the intercooler. Compressed, cooled air comes out of the intercooler via the lower-left pipe and blows into the Roots blower (via the EFI throttle body) at the top of the picture. Roots blower is bolted to the intake manifold and blows directly into the engine.

remember the AMT "Iron Horse" Mustang?
Ace-Garageguy replied to 62rebel's topic in Car Kit News & Reviews
Exactly. That would allow the nose of the car to 'point' lower, and make the rocker line either parallel with the ground, or slightly raked down-in-front. This would also bring the front of the roof down, but point the tail up slightly. The overall effect would be to match the slight rear 'sectioned' appearance Rob Hall mentions, and get the mass of the lower body to work better with the chopped top, as Rob Mattis refers to. From the windshield back, for a hot-rod road-racer '60s vibe, I think the car is just about spot-on. -
Stupid things people say at car shows

How many teenage girls can fit in it ?? -
Well, I watched the video walkaround (good shots of the plumbing start at 7:11) and the turbo compressor outlets are plumbed into an airbox that sits under the phoney injector hat, and over the carbs. Now I'm back to my original position on the rig...it just about has to lose all the turbo boost when the "injector" butterflies open. It can still run fine as a suck-through (carbs), mechanically supercharged engine, but the turbos aren't actually doing much of anything except perhaps SLIGHTLY raising the pressure above atmospheric BEFORE the carbs. Full blow-through carb setups are notoriously difficult to tune, and require things like sealed throttle shafts and interesting compensations to make the power-valves work, etc. http://www.enginelabs.com/engine-tech/carburetors/how-csu-builds-blow-through-carburetors/

If you look carefully at the photos and the illustration of the Camaro (which I failed to do earlier) you'll see that the turbos are blowing into the manifold AFTER the blower. They would have to be blowing into the inlet side of the blower (the top) to have the effect of raising pressure above what the blower is capable of delivering when the intake side of it is at atmospheric pressure. Properly plumbed compound turbo-blower. Air filter to turbo compressor, to blower, to intake manifold. Yes, as you say, THIS setup will raise boost considerably.
-
The concept is that pressure isn't necessarily additive. IF the Roots-type blower is making, let's say, 20psi (pick any number, really...don't go arguing about how much boost a blower will make), and IF the turbos are only delivering air at say, 10psi, the 20psi will leave the intake manifold heading into the lower-pressure turbo impellers, and stall the airflow coming from them. In principle (juggle the numbers as you see fit) a 20psi output from one airpump and a 10psi output from another airpump, both blowing into the same manifold, will not make 30psi. Maximum manifold pressure will only be equal to about the maximum pressure available from the compressor that makes the most boost. COMPOUND turbo-supercharging (or compound mechanical supercharging) works, usually, because compressed air LEAVING one compressor (either the turbo or mechanical supercharger) is fed into THE INLET OF THE OTHER compressor, which raises the pressure even more.

Indeed. I'd like to learn more about getting power directly from the grid, I assume, during operation. Nicola Tesla had supposedly developed technology making it possible to "broadcast" electrical power sufficient to do actual work (as opposed to weak broadcast energy streams like radio). I have a 1955 copy of Motor Trend that has an article about an early hybrid (yes, 1955), the builders of which also claim to have broadcast energy technology...and it was to be the next step after the hybrid.

remember the AMT "Iron Horse" Mustang?
Ace-Garageguy replied to 62rebel's topic in Car Kit News & Reviews
The only real problem with the design I see is that the nose sits too high. Move the wheel openings up in the fenders, and drop the nose. I think you'd like the results. -
So what happens to the pressure when the butterflies open??? Think like a manometer. It blows out the front (it will ALWAYS take the path of least resistance, and it's easier to flow out the front than it is to flow through the restrictions under it). Or correct what I'm not getting here, please. EDIT: I completely and stupidly failed to notice that it was the intake side of the turbo compressors that is plumbed to the injector hat, so there will be 'suction' (negative pressure) behind the butterflies with the engine running, rather than positive pressure as I mistakenly wrote above. My apologies for my momentary lack of brains.
