THE ROAD TO RADWOOD - Part 1

“The best laid schemes o' mice an' men………..” Robbie burns said that, way before Quattros were invented. Still applies today.

When we left you we had just installed our center console and were about to start working on installing brake lines before we put the engine in. Well that plan got blown up as the car got invited to Radwood Detroit, the car show for 80s and 90s stuff. So our first thought was “Nah, It’s not finished” but then someone suggested that if we got it on its wheels and put the engine in it would still be cool and people would love to see it. So that’s what we did, or tried to.

So this was our starting point, with the engine on a stand and just shoved into the engine bay and the car still on the wooden build table.



We didn’t have a plan for getting it off the table but thought it would be a dam site easier if the engine was still out of it. But first we had to prep a few things. Chiefly bolting the front tie rods onto the uprights. We hadn’t sourced nuts yet but realized some lug nuts of the correct thread would do for now:



And that we’d also need a steering wheel in order to manipulate it around.



We temporarily installed the rear firewall (again):



And rigged up the door strike pins so the doors would stay closed:



We also bolted down the Corbeau seats as best we could. Some adjustments will be necessary before final assembly:









Next time we'll mount the engine and transmission together and get it bolted to the chassis.

THE ROAD TO RADWOOD - Part 2

We thought we should mount the transmission as well as the engine only has two engine mounts. We figured the whole package would be much more stable mounted together. We don’t yet have a flywheel or a clutch but neither of those are necessary just to bolt the two lumps together.









We recently sourced some pin stands from Motamec in England so our plan was to lower the car onto these initially as that would only mean dropping it a few inches. Plus, the screw jacks we planned to use at one end of the car were to long to allow the wheels to reach the ground in one go so it would have to be a two-step process anyway.





So our plan was to lift the rear using screw jacks on the subframe, as far apart as possible and the front using our engine stand. Once we could slide the table away we would incrementally lower each end of the car onto the pin stands then off those using our high lift jack. This is how it went:

That’s the first time the car has been on the ground in about fifteen years!

Now the easy bit, throw the engine in and put it in the trailer. How hard could that be with no front on the car:



But wait, what? Who knew the AAN engine brackets wouldn’t line up with the Quattro engine mounts? Oops.





A quick swap to the 10 valve units and we were back in business:



But what’s this? Now the hood won’t close!



Will we make it to Radwood after all? You’ll have to wait to find out.

I really like the Motamec kit.

Can you post a few pictures how you mounted the sleeves to the chassis?

Thank you

I'm curious what keeps the hood from closing? Is it the intake manifold? there have to be other people running that manifold with that hood

Our cage builder or body shop did the sleeves. I don't have any pictures of the process and I don't think there is much to see now bbut I'll have a look next time I'm up there.

For now perhaps this video will be useful.

The reinforcement ribs on this hood are about twice as thick as the stock one so that is what interferes with the intake. A future update will address it.

The throttle assembly looks like its sitting a bit proud.
On my '84 with MTM intake, because I used one of those phenolic spacers, it pushed the assembly high enough that it would touch.

Yes Martin, our adapter inadvertently kicked it up a bit. And we also have the phenolic spacer.

We Made it to Radwood!

It turns out this super easy, bolt on aftermarket intake manifold just keeps giving……………us problems. Now the engine is in the hood hits the throttle body, even after we built a custom adapter to stop it hitting the alternator! Well, we soon realised we didn’t need a throttle body to push the car into the trailer so we took it off and adjusted the hood pins so it at least could be locked down. We’ll figure that out later.

So we pushed the car into the light of day. The first time it has rolled on wheels for fifteen years or so. It was during this process that we realised an eyeball alignment is not really accurate and properly aligned wheels make pushing so much easier! It wasn’t bad in a straight line but with the slightest amount of steering lock and it became very difficult. Still it looks pretty good in the day light.







And In. Yes, we used the trailer winch.



The car was very well received at Radwood and look resplendent parked alongside its stable mates.









We must admit, getting the car in the public eye inspired us to push harder to get it finished. We might even have a deadline now!

Looks fantastic, keep up the great work!!!

HOOD CLEARANCE

Back from Radwood we were inspired to get the car finished for next year. Not the least because we realized that 2020 is the 40th anniversary of the Quattro as it debuted at the Geneva Motorshow on March 1st, 1980. We don’t think we can get it ready for March but certainly having it done sometime in 2020 seems a worthy tribute. So lets get cracking!

First we have to get the hood to close. It turns out the strengthening ribs on our fiber glass hood are about twice as deep as the stock hood’s. That and the fact that this engine was never meant to go in this body are hopefully why there is interference. We hope so because we decided to cut a big hole in the hood!





And then make it even bigger!





It fits now and is almost smiling.

MIRRORS

It’s nice to conquer the big projects like intercoolers and radiators but sometimes those plans get stalled due to parts availability or even just the magnitude of them. Then it can also be nice and quite gratifying to check off a small project, even something as seemingly trivial as door mirrors.

Yes, we installed the door mirrors. But first we had to track some down and then decide where to put them. These cars in period were never quite the same as one another but they all seemed to share a common mirror, the now ridiculously expensive, for a mirror, Talbot bullet-shaped classic:



Price for new ones are over $300 each but, of course, something this easy to copy has been replicated by many and we found a set of knock offs in in England for just $65 .



Next massive decision: where to mount them? Some cars had them mounted to the doors in period, including the Rothmans cars after which ours is modelled. Others had them on the triangular part at the bottom of the window frames where the road car mirrors were.



Both locations position the actual glass in more or less the same place so functionally there is little to be gained with one or the other. If they mount to the doors they seem to be white and if on the window surround they are black. Also, if we mount them on the window frames we still have the problem of filling the hole left by the original mirror.

At this point is should be clear where ours are going. Yes, on the window frames. They are already satin black so will not need to be refinished and they will automatically fill that little triangular hole. Well, the mirrors won’t but the triangular plate we’ll have to make will.

First mockup took a lot of trial and error drilling.



Which left quite a few additional holes on the inside, which, to be fair, was always going to need a cover anyway.



We initially mocked it up in cardboard:



And then cut them out of 1/8” aluminum. A bit shorter as we realized we needed to extend the top bar in order to mount the door card.



But then we found a piece of very thin carbon fiber and decided that would be way more appropriate, especially as the surface wasn’t flat anyway.



We still made the outside pieced out of aluminum as they had to span a large void.





That gave us everything we needed.



Just had to slap it all together.









We may paint the screws and washers black one day.

Throttle body, power steering, alternator. Pick any two!

Yes, that's the conclusion we have come to trying to locate all the ancillary components in the engine bay. Right now, everything wants to be on the left side of the engine in front of the radiator. Remember, on these cars the radiator is not in front of the engine but to the side on the left. Because we are using an aftermarket intake manifold the throttle body is very close to the power steering pump. In fact, if we orient it correctly it is inside the power steering pump. We think we can rotate it 90 degrees and still mount it, though only one of the mounting holes lines up right now. Some adaptation will be necessary but we think we can make it work. Anyway, it has to be that way round to clear the hood and there is not really any room for an adapter. Even then, another issue is the outlet from the power steering pump still interferes with the throttle body, even after sourcing a really flat banjo bolt. Also, the outlet from the head coolant manifold is behind the power steering pump and very difficult to mount a pipe on. It's also heading in the wrong direction as it needs to end up behind the radiator. The coolant outlet from the block is also very tight where it passes the back of the power steering pump. Can we do without power steering?





Certainly, if we remove the power steering pump from the equation it creates some room but we are then left with an alternator stuck way out in front of the radiator and without much triangulation for the belt and no free length for the tensioner to push on. Maybe we should convert the power steering pump bracket to a second idler.



Another problem came up though: we can't seem to find a replacement alternator with the 200 amps or so we think we are going to need to power the six driving lamps and everything else.

So now we have no power steering pump, no alternator and a throttle body that's held on with one bolt! What should we do? Well we think we have an elegant a solution. Firstly, why not use an electric power steering pump? They are readily available used from a variety of cars including Volvos, Toyotas etc. They can be mounted almost anywhere you can get lines and wires too as they obviously do not need a belt to drive them. They will also work even when the engine is not running which might be useful around the shop or if the engine blows up mid stage. Here’s an example of a Volvo unit.



Then we realized, if we are prepared to make a custom alternator bracket, we could use any 200 amp alternator from any vehicle. It just so happens that we have to make a custom bracket for the front engine mount on the other side of the engine and there is a nice alternator sized space doing nothing next to that. Why not source an inexpensive 200 amp remanufactured alternator from a Ford truck and mount it on the right side of the engine on a custom alternator/engine mount bracket?



These two solutions, if possible, will then result in us having only an intercooler outlet pipe in front of the radiator which can’t be a bad thing for cooling air flow, right?

Subscribe to find out if any of these work out or if we go back to the drawing board.

Sorting out Radiator Choice, Placement & Mounting

This is the original radiator in the stock location.





We want a much bigger aluminium radiator as this one probably isn’t big enough as it worked in conjunction with a smaller auxiliary radiator mounted behind the grill. We don’t have room nor are we inclined to use that.

We found two companies that purport to sell a suitable radiator but neither returned calls or emails so we assume they are no longer supplying them. I guess we are making our own or at least getting one made for us. There are a couple of issues to consider: Any additional thickness will have to be in the front as the frame rails bend inwards just behind the radiator.



The stock radiator interferes with the AAN’s oil pan. We think this is usually solved by replacing the old pan with one from something else but maybe, as we are doing a custom radiator, we can solve it another way.



We were lucky enough to find a superb radiator shop nearby, Four Seasons Radiator Service in Madison Heights. Their bread and butter is fixing radiators of all kinds but they also make custom aluminium radiators. They are the company who recored the radiator for our 85 Quattro a few years ago so we were very confident to use them again. They took our requirements and in just a few days produced this masterpiece. They even added a Spal fan and custom shroud.





It fit perfectly but there was one small problem. Remember how we thought all the extra width had to be on the front because of the frame rail? Well we forgot about that when we asked them to add a fan and shroud. Simple solution though: notch the shroud:



Now we haven’t lost our cool we can move on to the intercooler.

That radiator looks great .
Actually the whole car looks amazing.
If you decide you want more clearance, switch to use a 7A pan and pickup tube and it will gain you some space . But from the pics it looks like you have enough .

Cheers mate

Progress with the Intercooler

Despite all the confusion about where things are going to go a couple of components are fixed: the radiator and the intercooler. So we pressed on with the intercooler.




We wanted to place it as far forward as possible while remaining inside the grill’s envelope. This meant cutting our expensive bumper up.




We couldn’t find an off the shelf intercooler with the correct inlet and outlet orientations so we decided we’d have to make our own. We ordered the biggest core we thought we could fit.




The intercooler will sit on the front bumper bar but will also need an upper support bar. We fabricated one from an aluminium closet hanger rod.






And then set about mocking up the tanks.

Before finally making an intercooler!










Which actually didn’t leak!



And, surprisingly, even fit!

Moving into storage temporarily...

They say “all good things must come to an end”. Well, this good thing has come to a screeching halt but not the end. We finally had enough of our landlord and upped sticks. We were already looking for a new building but the situation in our old space became untenable and we quickly decided we could just put everything in storage for a couple of months while we found a new home. Then the virus hit! So we still don’t have a space but we also don’t have a big rent bill every month so now we look smart. We’re not. The business is still going strong. Just not working on car projects right now.

Here are some pics of the move:

We decided to store it on the wheels from our 85 Quattro because the tires are 12 years old and shot and we didn’t think exposing $2000 worth of Michelin historic rally tires to freezing temperatures was a good idea.



At least we got a chance to try out our new E-Track tie-down system in our trailer.



Sad showroom



New home. Ramp was a bit steep but three wimps managed to push it in, though we had to take it off the dollies.







So now it sits surrounded by junk. Can’t wait to get a new showroom and get it finished.
