WHAAAT DID YOU SAY!!!

... and you bought a Syncro .....

Cool job!

Now I am only guessing here from memory of a 1z Audi 80 I had some years ago, a diesel of that vintage should give its max torque at 2000rpm and the torque curve should be fairly flat after that up to 4000rpm. I have no idea on what effect a mechanical pump conversion would have to the torque band. Max power for a 1z is a 4000rpm.
For a JX TD engine VW give 2500RPM as the point of max torque but the 'sweet spot' is around 3000rpm where it ill sit all day. Judging from the graph I have, 3000rpm equates to 95% of max torque and about 80% of max power. So if I were to attempt with a 1z what you are doing, I would reckon on trying to get my desired cruising speed at around 2500rpm minimum

Andrew, A bit after the event I know...but if you take a look at IG 16 and the thread about 2E engine swaps there are some interesting comparisons with various VW inline 4's and P/T graphs. I name-dropped it in my thread about the Sharan ADY destined for our syncro:

Here's the one at ig16, it's about 15 pages though:

Its heavy going is that. There is one post that says the ADY engine wouldnt be the best for off road work. Quite what that means I dont know.

The 2.0l ADY


Compare to JX with and without intercooling


And an elusive 1z graph


It seems like a good conversion but still not as fuel efficient as an intercooled JX! Some interesting comments re AAZ vs JX intercooled.

hi - some well, erm, interesting posts.

Lets qualify some comments (vlux your bob on for me too)

I`m running a 16 inch DOKA which had 6.16 and a 1z in it when I bought it. On 6.16 yep its was great off road - on the road you went into a coma going any distance and were thrashing the nuts of it doiung 50+. I spent hours looking at solutions with Aidan - and I checked around the numbers that most of the other guys went for like Russell, Mcgill etc. Came to the conclusion the 4.86 was too high and dont regret it IF you want an on road/off road hybrid. Remember its all a compromise. Went in the end (Aidan your patience was legendary) went for the 5.43 and lengthened the top two gears with a 0.7 as the highest. I`m running 235 70 tyres to memory and any more gearing would be too much too unless I had a better engine. Van cruises at 60 at 3k revs

Nothing wrong with an AAZ but it aint got the balls of a 1z or ahu or better. I`m still on standard pump with a boost box and bigger injectors and she runs fine - though an mtdi and charge cooler would be more ideal. Getting the heat out of the engione through a charge cooler would be a priority (or an oil cooler like Baxter sells)

Nuff said. Get your cheque book out - its gonna hurt! But regrets - nope I havent got any. The drive is sensational.

Well bigblue16, there is your answer right there and as Jools says ...... get your chequebook out!!

You beat me too it Syncropaddy I was just reading this and thought I might post exactly that. This is actually one of the options that Aidan suggested as a good compromise. My tyres are a little smaller at 195/75/16 and that gives me an option to re-gear it cheaply with different tyres next time I'm going through Andorra.
Now to sell the idea to "she who must be obeyed"...wonder if I could hide it in the grocery bills?

One other question does anyone know if you can still get the little gearsets to correct the speedo - for when I finally get all this done? I bought one once for my 73 superbug in Oz back in the day but can't remember where from.

cheers
Scott

This is where it goes wrong ..... because of the various combinations of gears/FD/tyres I doubt if you will get one to suit. My speedo runs 16% slow but I used a satnav to calibrate it so I know what speed Im going

Send it to Speedy Cables in North Wales - tell them what tyre sizes and gear ratios you have gone from with the original speedo, what tyres and diffs you have changed to and they will do the rest. Good service - they did my Rover P6 V8 speedo when I went from Auto to 5-speed manual. Not particularly cheap or quick but the work was A1.

Thanks for that SB just the ticket - found them here:

http://www.speedycables.com

read the website and noticed a lot of pushing of T3 and chalk marks and bits of rotating cardboard. I would think you could give them a set of GPS (SatNav) readings and Speedo readings at a range of different speeds - would be more accurate and quicker I would think?

Methinks I'll send them an email.

For syncropaddy et al who expressed some interest in my daily driver at work:
Thought you might be interested in recovery techniques when one of our MTLB (Armoured Personnel Carrier) broke through the ice cover yesterday while scouting access routes across frozen marshes.
The attached pics show:
1. The MTLB sunk on its side with skid mounted pivoting "recovery crane" in front on the wooden supports.
2. MTLB being lifted clear of the water.
2. recovery in progress : 2 MTLB's towing the lift crane forward with another two hauling on the lift crane wire which pivots the "crane" and raises the front of the vehicle so it can be dragged onto solid ice.

This technique, although looking pretty primitive, is amazingly effective and they recovered the 12 ton vehicle in an hour or so.

This "crane" may be something for the 80-90 crowd to make up, in smaller scale, and put on a trailer to take green-laning for when someone drops into a really deep hole! Or next time you are cruising accross frozen marshes perhaps?
cheers,
Scott

O H M Y G O D!!

Speechless!

That must've been a bit of a shock for the driver and crew.

One word ...... Jaysus!

Its a different world isnt it!

Nah! Happens all the time. These Ruskies are as tough as old boots.
In fact, in the marshes sinking is quite a slow event as the marsh is like a semi-frozen "slush-puppy" (frozen crushed ice drink?) for quite a way down and has a lot of biomass holding it together. If the APC sinks in a level attitude it tends to float for a while once its belly hits the surface. The driver and crew (in the back section) generally have plenty of time to get out.
Sinking in a frozen lake is a different proposition as once the surface ice is broken the tank goes straight down.
