I love Greg’s videos and the minute, deep-dive, technical details. It’s just a shame he can’t put the car into a pressure chamber and produce grainy charts of manifold pressure, horsepower, at different altitudes, with and without water injection, as if it was a P-51.😊 I remember that decades ago when I had a 124 spider, Al Cosentino sold metal replacements for the driveshaft coupling doughnuts from his Faza shop. I’m surprised there wasn’t an off the shelf equivalent for the Alfa drivetrain.
Rats Greg! You made me feel nostalgic... I was the proud dad of a black. 1982 Alfa Romeo Spider Veloce from 1982 to 1995. Brought my first daughter home from the hospital in it. Also took my driving test in a 1968 1600cc Julia Super. Alfas forever!!!
... it has an air-raid warning horn installed where a supercharger would normally go. I thought Hamas was gonna start launching rockets during the dyno pull.
Greg is actually anAshkenazi settler running his garage out of a Kibbutz illegally occupying the West Bank. Who ,other than a Mossad agent, would have access to so much technical specifications and data packages on German experimental aircraft?
Never associated your aircraft videos and Alfa Romeo. Your L -Jet tune up tutorial helped my GTV6 immensely in the past and used your hoses on my buddies GTV6 3.0 build
Well done! That is certainly a terrifying amount of grunt in a classic spider 😁. The one thing I'm interested in now though is how the handling balance could be restored with this significant increase in torque? Uprating tyres and brakes is obviously a must but then you start running into problematic roll, dive and skipping on the track, uprating the springs, shocks, bushings, mounts and sway-bars leaves you with significant body flex and a jackhammer ride. In the end you'd need to have body braces, additional welds or even a partial roll cage. Not to mention any additional fixes needed for the inevitable drivetrain issues you've already partially mentioned. I may be completely wrong though, alot of classic alfas I've experienced have been extremely accepting of significant drivetrain and chassis modification, especially the transaxle de dion models. Racing is not just in their blood but their bones and even DNA from the factory. Great content as usual and excited to see more of this project in the future!
Greg, Hey I just watched your Beaufighter, Underrated episode and learned you grew up near Venice Beach where Revell was located. My model building started with wood models, where I remember building a Lockheed F-94C. Anyway, I grew up just south of Venice in Westchester/Playa Del Rey and graduated from Westchester High. I remember back in about 1970, I came within an inch of buying still one of my favorite cars and designed by Giugiaro, a 1969 Alfa 1750 GT. If you remember it, the early models had a winged seat and a unusable rear seat which made it a much cheaper to insure "sedan."
Phew, I bet that thing is fun as can be. Couple weeks back, there was a rollcaged, tastefully restomodded Giulia Junior 1300 parked in the neighbourhood, car was done just right in my opinion, and you could see it was getting used, and not just as a tracktool. One of the few times in my recent life that I felt "car jealousy" and walked around it two times before going to work... now something like that with a supercharger - give me three days of good weather and it'll see at least a dozen alpine passes.
It’s a nice flat curve. I’d like to see what it would do with a port, polish, springs, cc’d chamber, valves, cams, and headers. I know you’d get into the vicinity of diminishing returns, but I bet there’s another 30+ hp left on the table there. It’s a cool car. If you ever make any 2JZ parts let us know, I’ve got an old SC I piss my money away on regularly. 😂
Fiat, Triumph, MG, and Alfa spiders were generally lucky to have 3 digit horsepower numbers, but they were all quite fun. I am guessing that 170 at the wheels puts that car in the dangerous-fun category. I like.
I do love twin screw super chargers, but they definitely made a lot more power on the Miatas I tuned. It was no problem to make north of 230 ft/lbs of torque and 250 whp with a 0.62 l/r twin screw on a stock 1.8 liter miata.

Thanks, I do like the Datsuns, the Roadsters and straight six Z cars. SDS is great, I'm making a kit for the Alfa to make it as close to plug and play as possible.
Right on. Equipping the 280z with SDS was straightforward cuz it’s the first year model of Z to have factory EFI & it was easy to retrofit. Before 1975, all US-spec Z’s had dual carbs, but my ‘73 240z has also been converted to EFI with a later “ZX” model turbo system-now reverted back to carbs for originality, but I kept the entire ZXt engine setup & plan to install in the 280z no doubt along with an updated SDS controller. I’m glad you’re a Datsun Roadster fan. I’ve driven a few & currently own two, which includes an original 1967.5 2000 “Sports” model (5spd,OHC) w/matching #’s. About 1000 were built. It was a very lucky find. Thanks again Greg!

Hi Mark, for the most part I only made these videos when I'm on layovers for my airline job. So that's were I get the time for that. As for the automotive stuff, it's my hobby and I do that stuff on my days off. My kids and other workers run the place so I don't really do that much there anymore.
I had a 916 spider but not the V6 ☹ It was still a lot of fun and girls seemed to like it! 😀 Nice video Greg! Would an intercooler make much difference, or just unnecessary expense?
Ah, to be 40 years younger (so I could get into and out of the car) and quite a bit more wealthy. Back in the day, when I was really a car and engine geek, I'd have been all over this sort of thing. I've never understood higher math, which kept me from becoming an engineer (either automotive or aeronautical), but as a much younger man, I was definitely an enthusiast, driving an amazingly unreliable MGA, then a "Formula 'S' Barracuda, and I kept up with lots of reading. I actually know the theory of how a 4-cycle gasoline-powered engine works, the apex of a curve, etc. - none of my high school and college acquaintances had a clue, so I always won the arguments that inevitably came up in 'car talk' bull sessions. Now, it's interesting, but I don't feel like I'm being deprived because I don't have a cool car, and don't feel compelled to tweak what I'm currently driving.
Greg, what’s the ideal cartridge for self-defense against Sasquatch? Also do you have any advice on what to do if you encounter one or any other relic hominids when in remote, wooded areas?
Hi Greg thats a nice sound ,,i have several older volvo 544 B18/B16 and 121 B20 i have been thinking about supercharging a healty B18 for some time now it has a bigger 2 barrel carb (flows same as the volvo sport twin SU) and a exaust manifold ,any idea what type i sould use? i have been looking as a mercedes 1,8 komsressor
Greg, make a video on S.P.I.C.A. mechanical fuel injection. My grandfather has an ALFA Romeo Montreal that has it, it would be interesting to compare it to Bosch K-Jetronic, which I would consider to be the most reliable and dependable fuel delivery system ever devised.
The older cars have a much larger fun factor for the same performance. Especially when driven in winding roads. I would say this car is faster than it needs to be. Especially given the limited protection of the convertible body. And the water injection complicates things. I would reduce the boost some and get rid of the water injection. The car reliability would improve, and possibly the car will be easier and safer to drive fast in the twisties. Sure, you will lose a few drag races against low end performance cars, such as, say a Challenger V6, but so what? There is a lot more in driving than drag races. Your next Alfa should be a 1970 GTV. As for me, I do my driving in twisties with a Volvo 122 (maybe more than one). Much slower, but the more robust structure make you more brave! Cheers.
Running lower boost without water injection is not problem, although I like the extra power and the water injection, but to each his own. I suppose part of the beauty of supercharging is that it's so customizable with different pulleys and boost levels.
@@GregsAirplanesandAutomobiles Just don't get killed! ;) I hope your system has a knock sensor to retard the timing in case your water injection stops working.
These engine don't have knock sensor, but the water injection has plenty of warnings built it. Certainly more than you get for a clogged fuel injector.
@@GregsAirplanesandAutomobiles The intensity of the knock at high boost with no or reduced water injection will be much more severe than with a clogged injector, and more likely to damage the engine. Also, if you drive the car regularly, there is no reason to have a clogged injector. But I see the other side of the coin. Having an old car like this with so much more power than stock has a certain level of novelty. I like to use my old cars as transportation as well as fun. As a result, I appreciate the simplicity of the old machines, and of course the fact that they are analog as opposed to digital, its man and machine. When one makes modifications like this, you start diluting some the simplicity factor. But to your credit, you have not gone that far yet on this one! The old Volvo engines are very good in handling boost because they have a very robust bottom end. Some people have installed super and turbo chargers on them. But I have little motivation for that. Even with 15 psi of boost, any of my near stock 440s will be a lot faster in the straight line. And in the type of course that the Volvo is fun to drive, the extra power will seldom be useful. But if I lived in Europe or Japan where you can only have one car, I would be tempted. Cheers.
Thanks Greg, you sir are a man of your word! Guessing 24V bussos aren't abundant in the states, but a good 3.0 or 3.2 makes 220-250hp at fly, so a bit of a bump compared to old 12Vs!!
The highest 24valver we had from Alfa here in the US was about 230 flywheel horsepower. Putting one of those into a Spider is a nightmare, and yes, those engines are rare here. The supercharged 2.0 is in my opinion a better option. Less weight and a lot of power.
Agree 100%@@GregsAirplanesandAutomobiles wouldn't suit the character of the spider anyways. Spiders have standard gearbox bolted to engine or transaxle ala alfetta et al? Also, why not soften initial supercharger hit by running hotter cams and shifting yorque max a little up rev range?
@@jacktattisI could have sworn that I have seen Lancias in Melbourne as we have a pretty sizeable Italian population. We also have a sizeable Greek population but I don't recall any cars made in Greece? Mark from Melbourne Australia
That poor power steering pump 😂. What's the drive ratio ? That it makes such noise even at idle makes me question if it has a bypass feature for low load conditions. See how Eaton and other blower mfg package one into the blower case.
Also the bypass in an Eaton can essentially shut off the supercharger because it doesn't compress internally. This one on the Alfa is like the Supercharger on a Challenger Hellcat, it's a screw type. It still has a bypass but it's not quite the same. It's compressing no matter what. The upside is, it can generate a lot more power. On this subject, I wrote an entire book on supercharging and covered all of this. It's on Amazon and in the Patreon section.
@@GregsAirplanesandAutomobiles thank you for explaining. Perhaps i missed if you stated the supercharger type. That degree of noise is very similar to a 24 hr Lemons mercedes that I see at events in the Southeast.
From the factory this car has four wheel disks and a good suspension. However after sitting in the shop for over a decade the suspension bushings are all in bad shape. I'll need to overhaul the suspension to get it really right. I'm also adding a roll bar.
Love those Duetto Spyders, especially the old boat tails.
Yeah, classic! Just wish they built them better especially rust-proofing.😎
I love Greg’s videos and the minute, deep-dive, technical details. It’s just a shame he can’t put the car into a pressure chamber and produce grainy charts of manifold pressure, horsepower, at different altitudes, with and without water injection, as if it was a P-51.😊

Needs a little M/W injection, or perhaps some of that German "blau stoff".

Even with 15 psi of boost, any of my near stock 440s will be a lot faster in the straight line. And in the type of course that the Volvo is fun to drive, the extra power will seldom be useful. But if I lived in Europe or Japan where you can only have one car, I would be tempted. Cheers.
Thanks Greg, you sir are a man of your word! Guessing 24V bussos aren't abundant in the states, but a good 3.0 or 3.2 makes 220-250hp at fly, so a bit of a bump compared to old 12Vs!!
The highest 24valver we had from Alfa here in the US was about 230 flywheel horsepower. Putting one of those into a Spider is a nightmare, and yes, those engines are rare here. The supercharged 2.0 is in my opinion a better option. Less weight and a lot of power.
Agree 100%@@GregsAirplanesandAutomobiles wouldn't suit the character of the spider anyways. Spiders have standard gearbox bolted to engine or transaxle ala alfetta et al? Also, why not soften initial supercharger hit by running hotter cams and shifting yorque max a little up rev range?
Do you have a Lancia Delta Integrale 16v
They were never sold in the US, but I do like them.
@@GregsAirplanesandAutomobiles Lancia were not sold in Australia Fiat Alfa and Ferrari only
@@jacktattisI could have sworn that I have seen Lancias in Melbourne as we have a pretty sizeable Italian population.
We also have a sizeable Greek population but I don't recall any cars made in Greece?
Mark from Melbourne Australia
@@markfryer9880 I have never seen one They were better made than the Alfa I believe
@@markfryer9880 Yes they were here from 1961 to 1984 I never got to see one here/
Wouldn't be better to just stuff an LS7 in there? Everything is better with an LS! I crammed one into my toaster at home! The toast is bitchin'!
If I want an LS, I'll get a Chevrolet.
@@GregsAirplanesandAutomobiles My LSA is in a Cadillac, but I feel you.
What’s her curb weight ?
About 2500 pounds, which is about 300 pounds less than a same year Porsche 911.
@@GregsAirplanesandAutomobiles I’d bet she’s fun.
That poor power steering pump 😂. What's the drive ratio ? That it makes such noise even at idle makes me question if it has a bypass feature for low load conditions. See how Eaton and other blower mfg package one into the blower case.
It has a bypass. That has nothing to do with the noise level. As I said, I might quiet it down a bit.
Also the bypass in an Eaton can essentially shut off the supercharger because it doesn't compress internally. This one on the Alfa is like the Supercharger on a Challenger Hellcat, it's a screw type. It still has a bypass but it's not quite the same. It's compressing no matter what. The upside is, it can generate a lot more power. On this subject, I wrote an entire book on supercharging and covered all of this. It's on Amazon and in the Patreon section.
@@GregsAirplanesandAutomobiles thank you for explaining. Perhaps i missed if you stated the supercharger type. That degree of noise is very similar to a 24 hr Lemons mercedes that I see at events in the Southeast.
very cool
Nice power, How does she brake, how does she corner?
From the factory this car has four wheel disks and a good suspension. However after sitting in the shop for over a decade the suspension bushings are all in bad shape. I'll need to overhaul the suspension to get it really right. I'm also adding a roll bar.
SaaaaWEET! Ain't no "We're calling your Big Brother" spyware tech in that little jewel.
Exactly how did you get into European cars Greg?
My parents had them when I was little.
@@GregsAirplanesandAutomobiles Dad had a 64 Barracuda and a 72 Cuda. Kinda why I am a MOPAR guy.
What's up with the framerate? low fps camcorder, or something went wrong during editing process?
Ya I'm seeing that too. Guess he had dcs running in the background sucked away all the fps haha
The camera movement made me think maybe the video was being filmed while performing a lomcovak. 🙂
