Classic Fiat 500 engine upgrade. How big can we go; how about 695cc? Part 2.. 

Glad I read your comment AFTER watching the video, I'll just have to forget it before part 3😀😄😄

Indeed. Air cooled engines are something else aesthetically.

Episodes.

You’re right. They are partly what inspired me to make similar videos down under.

Yer. I love this videos on rebuilding these old cars.

Same here!! Competely agree

Steyr Puch engine is the logical step. They are naturally balanced and rev to 9000rpm. The 500 parallel twin shakes itself to death.

@@fraserwright9482 Part of the fun... so long as it's someone else's wallet.

My money is on Harry going for the multi valve head,just saying

@@williamtynan6484 I assume you mean the dual port head.

Plenty still here in Melbourne that I go to visit impart inspired by Harry.

This work won't come cheap though! Amazing stuff

I much prefer the 600s.

Classic Italian, it looks fun to drive and I'm sure it is.

It’s a beauty

Indeed. Some of the workshops I visit get a right slagging off because they’re not hi tech super clean ‘you could eat your dinner off the floor’ places. These places have soul.

I’ll be taking my little Alfa to somewhere similar here in Melbourne later this week.

We have the same issue in Australia. I’ve filmed at 30 odd workshops and there was a point when I’d seen just as many octogenarians working as under 30s. There are thankfully a passionate bunch of youngsters coming through. Unfortunately not enough though.

What torch needs to be carried? Father Time is undefeated, and so it is with niche old cars.

@@TML34 Don't forget to burn the books that reference any of it as well.

Of course they will disappear. They will become illegal to operate as ice engines are.

Well go ahead, take over the torch

Who are you calling ‘Sir Hat’? More to the point, why are you doing it?

No, it's the size of their piggy banks.

I read it as hats off to Harry, being a compliment.

Yes exactly. You could sense his disappointment when the Panda big valve head with twin choke carb was mentioned... Seems a bit directionless tbh- as in a bit more research and planning and he could have arrived nearer the ultimate spec. All good fun though.

Ahaaa that’s it. Thanks for reminding us. So many 105s land here in Oz, I wonder if we’ll see a 3000GTV landfall

The said Alfetta had a standard 2.5 V6 bonnet - so I suspect it's simply a 2.5 V6 car with a 3.0 75 transplant. Nice though.

@@georgebettiol8338 I was wondering the same thing as well. The SA version had a large bonnet bulge to accommodate the down draft Webbers.

@@DavesClassicGarageToursV2 There are at least 2 of them already here.

Spot on. It’s a 75 engine modded to more or less SZ spec. Ported head, new cams, tubular manifolds, lightened fly wheel. Nice, smooth, torquey and responsive. When it can breathe.

Plenty of them still around here in Melbourne too that I visit. Just another block of uber expensive flats if they weren’t there.

What kills these places is when the lease ends and the rent doubles or triples.

Harry said he was building this engine to produce more torque. If the flywheel weight is reduced so much the engine will rev quicker but will it have max torque much higher up the Rev range

@@llamamanismyes this build seems incongruous and a little hashed together regards the shaved barrels.

2.75kg off. Not 4kg.

These are the ones that get me going and inspire me to make more of the same down under.

How else do you drive a 500? Any 500.

@@GSimpsonOAMScared. No crash protection.

And dual-circuit master cylinder and electronic ignition.

With no care as to whether the investment increases the value of the car. I think he'd have been better off sticking to 595cc.

The employee at Ferrari that test on road all prototypes and car on development daily drives an old blue 500 😂

Was you slip streaming a Robin reliant? 🤣👌

@@tones61 nah too hot for a Resin Rocket...it melted.

Fabulous!

Would be nice to see how good it will accelerate - taking the 15 to 45 or 50 mph gps time before could have been helpful. From my personal experience with such work 50% of the possible improvement in acceleration may come from the lighter flywheel, the other 50% of all the other measures being taken. The increase in cc will almost do nothing because of the still small carb, and the overall better performing cam will make the engine rev up higher and have a little higher max power at a higher rpm and on overall wider torque band? But the 16% more displacement (about 600 to about 700) alone in the given configuration could make 5% more horsepower, or 8% to the max? We don't know yet, but hope to get some numbers on it all soon with another next video. (And how lean or rich to go with the carb settings? And are you going to measure it on the dyno? And what sparks to choose? NGK 8th?😊)

Come and see a load I’ve filmed down in Melbourne

The 850 is water-cooled. Impractical for an air-cooled 500. Works on the 600. My 600D has an 850 engine.

If you like this, we have loads of similar Melbourne based workshops we have visited.

The said Alfetta had a standard 2.5 V6 bonnet - so I suspect it's simply a 2.5 V6 car with a 3.0 75 transplant. Nice though.

Yes it’s great to see Harry championing these independent garages. We have so many here in Melbourne but the worry is there won’t be enough new talent in years to come to keep them operational.

Me too! Every time!
