Nice one Islandman,

It sounds nice and I'll be pinching the starter button in the engine compartment idea.

When a few more of the Novas are up & running we will have to invade the next London Tunnel Run!!

Your editing & effects are better than mine :oops:

I just really really like the way those engines look from the rear! For some reason the Subaru motors just don't have the same appeal. Maybe the Alfa is a little lower or if you take the cam covers off you can see the pulley's spinning. Shame I can't find one here in the States - but then who would work on it?

Oh, and Dave, how did you support the engine? I see braces going back, but I can't tell where they go, and your build photos aren't updated enough to show what your video shows. Just curious to see where the mounts were attached for future reference!

Scooby engines all tend to be 4-cam 16v these days. Later Alfa boxer engines are available with 4-cam 16v as well (1.7 litre/135 bhp).

Dave's engine is the single cam-per-bank 8v model, same as mine. The only difference is, when Dave wants to fit a 16v, he can, but if I want to my main chassis longerons get in the way of the new 4-cam heads :(

Never mind - 8v engines are tuneable up to 150 bhp for fast road use, and up to 200 bhp with aftermarket EFI (there's an Alfa 33 racer running a 220 bhp 16v engine here in the UK).

You're right Rick, Alfa Romeo never launched the 'Sud in the US, although they were planning to. You did get the GTV6 though, didn't you?

2.5 litre, all alloy V6, 190 bhp? Later available as a 3-litre (220 bhp) and now a 3.2 (based on a GM block, if you please, but with Alfa quad-cam heads)...

Yep, we got the GTV6 and the Spyders years back. According to the Top Gear magazine, it looks like Alpha is getting ready to come back into the American market some time in '09.

Rick,

Sorry I took so long to get back to you, I popped up to Kuala Lumpur in Malaysia for a long weekend, just got back so now able to sort out the photos.

The frame was made out of mild steel square bracket as shown below.

http://i187.photobucket.com/albums/x91/euronova/islandman/JAZ471-EngineMountBracket0.jpg

I welded to bracket holders to the trailing arms for the rear of the frame to bolt through as shown :

http://i187.photobucket.com/albums/x91/euronova/islandman/JAZ471-EngineMountBracket1.jpg

I then used the original gearbox mounting bolts to hold the second mounting point on the frame as shown :

http://i187.photobucket.com/albums/x91/euronova/islandman/JAZ471-EngineMountBracket2.jpg

and finally here it all is bolted together and intertwined with the custom made exhaust :

Lauren,

My Subaru engine is a SOHC 16V but I am considering replacing it with a DOHC EJ20 I have from a WRX a jump from 137hp to almost 300hp and that should make the back end drift a bit more. But for now the 2.2 litre does a nice job.

So Rick, what is it you don't like about the Subaru motors?

Kym

:lol: The space limitations on the first generation Sterling! Oh, I've got nothing against the Scooby swap - I just don't have the physical space for the radiator unless I give up all my up front storage!

My radiator sits in its normal position but of course it is now behind the engine. The crossflow aluminum radiator weights nothing and the amount of water in it is minor so the overall weight is insignificant. I use the stock radiator hoses and two aftermarket thermo's in the original subaru shrouds. Perfect. No overheating at high speed on the freeway on a 40 C day can't be bad.

I've piggybacked two rads in the engine bay on the drivers side at an angle and fitted an electric fan, pipework is a mixture of Saab, Renault Laguna and VW Polo items with two stainless steel half inch pipes down one side to the heater in the front.
Haven't ran it long enough to find out if it over heats or not yet but fingures crossed it will work if not, major rethink. Here's hoping.

Spacenut

Hi Rick - one other possibility, which to my knowledge has never been progressed beyond the design stage, is to put two radiators either side of the front compartment behind the headlights. I was considering BL Mini units, but some custom alloy ones sound like a better idea. You could use the air intakes in the Mk1 Nova/Sterling nose to feed the rads, with thermostatic fans in front (push, rather than pull through).

The extra weight up front would improve the balance slightly, although Polar Moment of Inertia (PMOI) goes up, but that's OK unless you are REALLY throwing the car about :D.

The usual Nova performance equation used to be to bin the VW and replace with a late model Porker, but air-cooled flat-sixes are becoming increasingly rare these days (not sure about over the Pond though :D), so more and more water-cooled conversions are popping up.

Kym, you have done well to ensure a rear radiator provides sufficient cooling - I have only ever seen the trick performed (successfully) once over here and that was Giles Briggs' Alfa powered Nova. I know Dave (Islandman) tried the same trick (in fact it was Dave's car that inspired Giles to put his rad in the same position!), but suffered badly from overheating.

having said that, nothing is impossible - the Lambo Diablo (and subsequent Murcielago and Gallardo's as well I believe) have twin radiators at the back of the car, flanking the engine - not within the wheelbase, as with the Countach, but behind the rear wheels, with hot air exhausting through large grilles each side. Theoretically this takes advantage of the low-pressure area behind the car, but radiators only work efficiently when there is a pressure gradient (differential) across them, which is where some configurations come unstuck. Lambos use ram-air intakes on the upper side bodywork (presumeably you are using your Eureka airboxes for this purpose Kym?) and big push-through fans in front of the rads.

Scoobies have come a long way since the 70's, but my boss had a 2.2 which kept blowing headgaskets and looking at the cylinder bore spacing I can see why. Its been bored out beyond the practical limit, in my view. I think I would prefer a 6-pot arrangement for this capacity, like the SVX. Otherwise it seems better to stick to a 2-litre and go mad with the turbo...

All food for thought!!!

I tried the rear radiator option when I first put the Alfa in (it was some time ago as you can see from the dodgy photo extracted from VHS tape!).

http://i187.photobucket.com/albums/x91/euronova/islandman/rearradiator.jpg

It didn’t really work at speed, I even had three radiators in the rear at one point :cursing: , but ended up opting for the front mounted which seemed to do the trick.

I guess it’s the air scoops that you added to the top side vents that make the difference, but I tend to prefer the original styling in this area .

Lauren,
I had considered that as well, as another consideration of twin motorcycle type rads behind the intakes in front of the rear wheels. If I was starting from scratch, with the body off the frame, I would seriously consider a watercooled swap. But with the car essentially finished, at the moment I think I'll stick with a traditional aircooled setup. Porsche flat 6's are available and come up pretty often on eBay here, but the weight differential and the fact I'd have to marry a Porsche transmission (and remote oil sump - they require one) puts the whammy on that as well.
I still haven't completely ruled out a Corvair conversion. It all comes down to money and where I want to put it when the time comes!

Rick

Well guys, the scoops are not used. In fact I am not using any of the vents for anything other than decoration. The rear radiator is feed purely from the 2 Davis Criag Thermo fan's and they come on and go off as regular as clock work. I tell a lie the passenger side scoop funnels air directly over my airconditioner condenser which is off a ford metro. If I can keep it cool in a Perth summer UK is no problem and the US shouldn't be either.

Not a good angle but you can see the radiator behind the engine. Below you can see the vents either side of the numberplate recess and the long vent running the full width of the radiator.

What engine management system are you using, Kym?

Spacenut
25-07-2007, 04:29 PM
Giles's car didn't use the air scoops either. However, his car did have an extended rear skirt (made out of a Renault 5 van front bumper we later discovered!) which intercepted cold airflow from under the car. This probably explains why Dave's otherwise identical arrangement didn't work. I see that Kym's Reek has a very similar extended rear skirt which may be offering the same advantage.

Plus a custom multi-row radiator always helps :D

Ahhh yes, the Chevrolet Corvair... plagiarism really was the sincerest form of flattery. Great base for loads of excellent concept cars though (a couple mid-engined no less) - Testudo, Monza and Monza Spyder, Bill Mitchell Spyder, Astro 1... Big Daddy Roth's "Road Agent"...

:D :D :D

You could even get a 190 bhp turbo in the later models... plus you could use the Corvair transmission as well if you wanted to (you could upgrade the whatsit valves for harder shifts and then change gear manually like the Vector did! Sequential shifting, 60's style!!!), and you still get swing axles!

Sorry, I'm getting carried away a bit :D

A good friend of mine was once asked what engine management system he was using in his Escort thunder saloon (300 bhp Cosworth RWD). Being a bit of a wag (that's wag, not WAG) he said "DRF"

"DRF" says the bemused onlooker. What's that?

"Driver's Right Foot" came the reply :D

Green Machine uses DRF too :D :D :D

Firstly Peter, thanks, I like it and it wasn't that difficult. A lot of the little mods I made I laid up over what I had for the master and then sanded back the outside and painted it rather than make a mold that I thought would never be used again.

Rick I am using the ECU that is stock with the Liberty/Legacy rev limited at around 7500 might be 7800 because I don't look when I hit it as I am so busy changing gears and in first it is on the limiter before you can click your fingers.

If I remember correctly the air scoops on the top of the wing actually draw air out of the engine bay and does not force it in when travelling at speed, unless you add the "ears". I think someone did this exercise in the states with sticking ribbons to the car and driving down the road and seeing what happened, (cheap wind tunnel) the findings were not what was expected.

Spacenut
26-07-2007, 12:27 PM
Hehe - it's not the first time that what people assumed were "intakes" actually turned out to be "outakes" lol

I am using mine purely as a cold air source for the carbs rather than ram-air cooling, so I'm not too bothered. Also, the presence of a higher pressure in the engine bay relative to the outer wing surface will depend on a number of factors that would vary from car to car. For example, if there was a pronounced rake to the body and very little underbody airflow was present (and more going over the top) there could be a net pressure differential that could allow airflow INTO the engine bay.

Also, getting air OUT of the engine bay area helps to establish a pressure differential between inside and outside and rear end mods will have a big affect on this.

Tuft testing. I was going to ask if anyone had done any on the Nova/Sterling shape. Also manometer pressure testing over the body shape, 'cos I want to know how effective my canopy air extractors are going to be :D

I'd add in mine as well, but I don't have anything to record the sound other than two things. My mobile phone, and that's a crap recorder, and the other is my digital camera. It's just a 3 megapixal still camera, but it can do a short (30 second) video grab. Again, sound quality is poor.

Ok, so I should have tried using my digital camera. But now my 'reek is in Sydney, getting some more work done on it by Ron, then Simon gets his hands on it.

Maybe one of them could get a recording for me. I'll have to ask them.
