curious as to power potentials with 1.6L td

[wolf_walker]

Are you sure the other drivers had any intention of trying to overtake you?

I didn't want to be the first to say it.  No doubt there is a lot of improvement to be had on an IDI TD, but really.

On the subie timeslips, that's still pretty good in my opinion.  Those motor's are so smooth too.

[erice1984]

Yeah, It sounds really good too.

I wasn't trying to race my rabbit at all, I just don't want to be beat by a geo metro.  In other words I don't want to be the fastest nor the slowest.

I am just looking for enough to get me to a reasonable power level and be able to maintain an 80mph cruising speed with ease and efficiency.

Just let me know if that is not possible of an IDI.

[wolf_walker]

Any healthy stock-ish 1.6td will do what you want, nothing fancy required.  The power don't look like much on paper but it's a great help in driveability out in the world.  The downside is decreased life and increased wear (which is debatable weather it'll matter to most people), a mess of plumbing underhood, harder to work on, etc, etc.  Same as any other turbo setup.  I've had both, prefer NA.    Healthy is the key, these motors will run forever and a day 3/4 worn out.  As most of them are and do if you look close.  Part of there charm.

For the 80mph with ease job, get a Quantum...

[erice1984]

Well my money is in the rabbit.  What does the quantum have that makes it quicker than the rabbit?

i have no idea what my car does for 0-60, 1/4 mile

his car or my car? the car has never been down a track. ever. and my rabbit is quick. way quicker than my GTI..

and yea, the guy in the suby wanted to race. shoulda seen his girlfriend sock him in the ribs. was priceless.

Your car.  You should really get some sort of hard numbers.

[honda_is_the_best]

well, before i go abusing it at the track, i need an intercooler, new rear engine mount, and some tires that are not 155/80 snow tires..

when i get the intercooler, i may even wind my fuel screw in some more, i have about 3 full turns to go before i run out of idle adj..

pump on my black car was maxed out at about the same power level. this one has a half mile to go before its maxed out.

and not like im trying to brag, but i had one of the coolest diesels at Waterland. definitely the loudest turbo'd street car that i heard. and it was a total sleeper on top of it.

This is a little late but I own a 1985 Golf with a 1.6 TD engine (out of a Jetta). It's intercooled too. I could not imagine driving a stock naturally aspirated VW diesel every day. The lack of acceleration would be exasperating but I think I lack the patience a lot of you have. The turbo makes a very noticeable difference and without one, I wouldn't really enjoy the car though my car lags quite a bit until my turbo is fully spooled up.

Anyway, my car is pretty fast for what it is (an economical car), I still haven't unleashed it's full potential as the restrictive stock exhaust is still there and the injection pump isn't tweaked.

It WILL easily overtake someone at 80 mph on the freeway which I think is what you're looking for. I have seen some priceless looks from people who were passed by an old VW diesel. I don't like to keep up with the Porsches cruising along at 90 mph on I-5, I'm not sure it's such a good idea to spin the VW IDI diesel engine that fast for long periods of time but I'm quite sure my car is capable of it.

[erice1984]

how does it impact the fuel mileage?

[rallydiesel]

If you want to be able to cruise at 80mph then I highly recommend getting a taller geared tranny. I have an ACN (common gasser trans) that runs way better on the highway than the typical diesel trans. I am also swapping in a .71 5th gear that will make it even better at highway speed. That's why these cars are so great, they're like big Lego toys.

[erice1984]

Yeah, I have an ASF.

[bajacalal]

how does it impact the fuel mileage?

You talking to me?

I have no idea. I'm probably one of the worst people to ask on this website. I honestly have no idea what kind of mileage my car gets. All I know is that it's better than almost anything else on the road and that it's still fun to drive. That's what's important to me. The difference in fuel consumption between 45 mpg and 40 isn't really enough for me to be concerned over anyway and I honestly think I would get worse mileage with a n/a car due to the fact that I would be using a much heavier foot.

And yes, taller fifth gear helps too with cruising speed and cruising mileage.

[erice1984]

right thats understood.. I was more speaking of mpg in controlled "experiment"

Maybe I will have to do that since I am setting myself up for it.

I was after something like this:
Using transmission "A"
on a naturally aspirated 1.6L Diesel
Over the course of ~2 months driving in temperatures of <enter temp here> I achieved an average of city/city+highway/highway driving mpg. Using some or none fuel additives.

After turbo/timing/tune
Using transmission "A"
2 months in temps of <enter temp here> mpgs, fuel additives..


You get the point.

It didn't need to be MIT scientific but a rough idea of what its like after turbocharging the engine.

my car used to struggle to go 50 mph up hills in 3rd, now i can pull hills at about 90 in 4th. 55 up hills is pretty much off idle. and it takes about 3 psi to do it.
