I usually find myself shifting around 3000 rpm's. If you were gonna take off in a hurry, how high of an rpm would you wind it out to? I was under the impression that your power starts to dip around 3500 rpm's or so...your input would be greatly appreciated.

Ive always heard 2500 RPM is the very best to shift at when driving normal, I think if your going hard i would shift about 3200 RPM.

It depends what gear you are going into. You'll need to play around with it and see what it fastest.

I guess I mean taking off in 1st and going from there. Where's the redline for these 1.6td's anyway?

4500-5k.. is redline.. stock pump and such..
my ahu with gov mod on rover pump pulls more then that though... revs like gas car..
when to shift is when it quits pulling IMO.. my 1.6 na, my 1.6td.. and my tdi-m have always been run good and strong...

I usually shift at about 3200 or so under normal driving, sometimes a bit lower (more like 2800) if I'm taking things easy. Jezzie cruises the best about 2200 RPM - she doesn't like being lugged around below 2K. If you drive her like that for a while she starts not running as nice after a while - I think it takes a certain amount of higher RPM running to keep everything happy with these engines.
You definitely won't hurt your engine by over-reving it. The 1.6 will go up over 6K happily, the injection pump however will start floating around then. Before any of that happens though the governor will cut out the fuel.
I take Jezzie up to 4500-4700 somewhat regularly (ie when I'm really trying to max her out, not under daily driving). She pulls fine all the way in to the mid-4's before she feels like she's falling on her face, but that's the governor kicking in rather than anything to do with the rest of the engine.

When I had a k24 I would shift as soon as I saw the boost drop off.
-running 25psi. probably 5-5.5k or so. maybe more, k24+gov mod+ custom boost pin + 1.6/1.9 head loves revving.

I try not to let the tach go under 2500.
Even if you rev high enough to have some power cut before the shift, at least you stay in boost. Shift early, lose boost, no power, long wait....

Thanks for all your replies. I forgot to mention this is a 1991 1.6td eco engine with a k14, giles pump, ic, and boost gauge seems to show boost to 20psi if that makes any difference.

ive pulled my car clear till the power goes flat.. like.. FLAT. thats around 5800 if i remember right..
my car revs like a gasser almost too.
usually, if i want the power, i would say that i pull it to atleast 4500..
normal driving, somewhere around 2k rpms..

Very unfortunately I don't have a tach, but I shift as early as possible. I hit 5th gear by 25mph, sometimes in traffic if we slow down to 20 I can manage to maintain 5th even. I just recently found a new miracle goo I was able to get for comparatively cheap, motorkote, and it cured alot of the vibrations from luggin 5th gear. Matter of fact I rarely downshift at all.. Makes for a slow ride but saves coins. I will string fourth till 35 if there's a hill

Kev, you and I both run these motors to the moon.
I think it depends on your transmission more than anything.. If you have a close geared AWY transmission than you could pretty much shift at 2700 and drop to the next gear at 2600 and still be on full power.. With the longer geared transmissions there is a bigger drop between gears, and thus to hit 2600-2700 on a up shift, you'd likely need to shift at 3200 or possibly more.
I personally shift when she doesn't pull anymore.. But I've had 3rd gear to 115km/h, and I think that's above 55-5600rpm.

I have the same motor as you sans the giles and IC. I have swappped in an ASF tran and lightened flywheel. Driving regulaar I shift at 3k. When I'm in a hurry I wind it out to 4500. No issues. Boost is at 20psi when stompin the go pedal.

8v-of-fury - I have the ACN 5 speed trans. From the consensus, it sounds like winding it out to 4000 or so rpm's isn't so bad.

Oh it most certainly isn't bad. The gasser 1.6 and 1.7 (with proper valve springs) could spin 8k rpm. They are more or less the exact same motor as the 1.6 diesels.. Diesels have a slightly more robust bottom, so they'll take whatever you throw at em.
