IDI Engine / Re: How much does winterr impact on fuel economy
« Last post by ORCoaster on Today at 08:09:28 pm »
You will see a dip in mileage during the winter.  Can't be helped.  Colder temps, different fuel mix and how you drive all play into it.  Stop and go instead of smooth light through light because the roads are snow covered or it is pouring rain and people just are being careful and slowing down.

Idling an engine to warm it up is just plain foolish.  A little bit of time to get the oil moving around to all the parts, a little extra sit at start up to get the injectors warmer is all that is needed.  You might be talking 2 mins at the most when the temps are in the teens and twenties.  The real killer is the cold fuel going to the injectors.  Some engines have preheaters in their fuel delivery systems to compensate for that.  Most early VW's do not.  Not sure about the newer ones. 

I generally see my in town mileage drop from 34 to 30 in the winter.  But my trips really don't get the engine very warm.  I do get heat in the car but the gauge says less than 180 by the time I get to work or back home.  That is still under the thermostat temp of 193 F.

ive kept my trip meter going since I bought my chevy cruze diesel a year ago. last winter I was averaging 5.7l/100km, the summer it dropped to 5.5l/100km with my average tank in the summer being mostly around 5.2l/100km. Not a huge difference but give or take 10%. I should also mention I don't warm my car up before I drive it. working some night shifts in the winter I would sit and idle to warm up so that is a factor as well. not for hours but 10-20min a few times over a tank of idle was usually enough to ruin a good tanks mpg

Just plug the fitting on the compressor.  Run off the intake for the boost gauge also.  You'll either need two tees or a cross.  Run intake to the pump, intake to boost gauge, intake to MBC, MBC to wastegate.

Thanks Libby!

What about the nipple coming out of the turbine? Plug it?

And where would a boost gauge fit in the equation? Probably best off the intake manifold? Or would the unused turbine outlet be a good enough location for it?

aking all this into account, I think I need to run a line off the intake manifold to a manual boost controller. From the boost controller, I need to tee the fitting running one hose to the wastegate and the other to the IP. Is this correct?

That's almost correct, but not quite.  You should not have the manual boost controller inline to the injection pump, just inline to the wastegate.  You should run it intake manifold -> tee -> injection pump + MBC -> wastegate.

Iím building an mTDI to put into my Ď82 Westy Vanagon. Iím in the final stages after years of blood, sweat, and tears (and lots of money). However I am new to turbos and want to make sure that I plumb mine in the appropriate manner. I have read, but cannot find a definitive answer anywhere.

My GT2052 is currently plumbed from the housing side to the wastegate. I have read that many people put a manual boost gauge in between this connection. I have also read that it is better the plumb the wastegate off the intake manifold (especially if you are using an intercooler which I am). My IP also has a pressure nipple on it. Iím assuming to increase fuel in line with increased air.

Taking all this into account, I think I need to run a line off the intake manifold to a manual boost controller. From the boost controller, I need to tee the fitting running one hose to the wastegate and the other to the IP. Is this correct?

I may also want to run a boost gauge. Can I hook this up to the turbine side of the turbo that I am no longer using or do I need to plug that connection and tee of the boost controller 3 times?

Totally engaged with the solenoid.  If you are just starting it with Jumpers that tells me I could be a dirty starter problem and possibly bad contact connection.  It is so easy to remove the starter that I would just pull it and service it.  Clean the contacts at the terminals and on the battery.  All should be well. 

I did take the starter out yesterday going to go get it tested in less than half an hour, gonna throw a new battery in and I got extra terminals ill probably throw on too,will let you know how it goes. Thanks for the help.

New to VW with some knowledge on vehicles. Just got an 81 Caddy 1.6 and having my first problem. When I got the car it would turn over fine, could turn it off and it would turn over again. Next day go to start it and nothing(battery is not dead but no click or anything when went to turn it over), so hooked up some jumpers, and jumped the starter with a ratchet and got it going, let it sit for a while turned it off and wouldn't start again. Went to jump the next day again because I like to start tinkering at dusk, anyway starter just whines and wouldn't catch. Solenoid or do these having something in the ignition that tells it to catch?

I agree with the resonator.  I tried a Rabbit without one for a time driving 4.5 hrs on the highway commute and was deaf from the drumming in the ears by the end of the ride.  Put on the extra piece and was never sad I did that.
