Timing 1.6TD

[2strokesmoke]

Hey guys,
I have a question,reguarding IP timing on my 1.6TD
First a little history:
Engine is from a 85 Quantum,installed in my 88 Fox wagon.
IP timed @ 1.05 with new belt and everything else LOL
Freshly rebuilt and Pop tested injectors
This car build is almost completed,with only odds and ends to finish up.
This is my FIRST 1.6TD- all priors were NA engines
The engine starts instantly (a little rough with some smoke at initial start) but runs great and starts easily below freezing,without block heater.
I've noticed that the 1.6TD is MUCH quiter (doesn't rattle as much) compared to my 1.6 NA which is timed at .92
Is this normal for the TD ? Should I advance the timing beyond 1.05 ?
I appreciate your input.
Thanks,Mike

I thought 1.05 was about the limit for a 1.6.  Maybe the TD can take a bit more but my understanding on the 1.6 was that closer to .92 was where you want to be.

I run .93 on my NA 1.6 right now and am comparing it to the .88 setting I had before the cold weather set in.

I too just swapped a TB and Tensioner.  Must be the season to be changing.

The number means nothing unless the pump is within new specifications.

So basically the best "number" is where it runs the best. Bump it up bit by bit until you get some clack, and then back a little bit.

When you say the n/a was louder, was it in a mk1? They used the solid motor mounts. Are yours hydraulic? It makes a difference.

8v tells it.  numbers only really work for reference on your car.  Good from a general point of view but the sound and the way it really runs or doesn't run is what we strive for.  These may be good cars but for crying out loud they are pushing 30 for the most part. 

Hagar had it nailed Hillbilly tuning.  Smoke and clack and rock er back.

Hi guys,thanks for your input.
Yes,the 1.6NA is in my 81 Caddy, which actually feels like it pulls harder than the 1.6TD in the Fox.
I must honestly say,the Caddy is noisey, I'm referring to engine noise (clack) NOT inside the cab.
I'have played with many different timing settings,before setteling on .92
This Caddy is definately the quickest Rabbit or Pickup I have ever owned.,while consistentantly delivering 42-45 MPG depending on driving conditions and payload (and wind)LOL
The 1.6TD in the Fox I set @ 1.04 but haven't played with it yet.
IP condition didn't even occur to me,to be honest.
I will try advancing IP timing and see if power increases as well.
I Have increased fuel to the point of smoke and then backed off slightly until there was no smoke.
Upon several test drives, Both the Caddy and Fox seem to have about the same power.
I used a crude method of running both vehicles down my street from stop sign to stop sign and both yeilded 40MPH.
The caddy feel like it pulls harder (especially in 1st and 2nd)
Maybe due to gearing,as Fox trans has a much Higher final drive.
Both IPs have same Gov Mod.
In my experiance,advancing the timing tends to move the sweet spot (or power band) higher in the RPM range.
Does this sound correct?
Have you guys experienced the same ?
Thanks agian for your input,
Mike
