1.9 TDI into 90q: resurrection and for sale

[dana]

I mean they last until they don't on alh's. You should be fine.

my ALH's flywheel made it to 240k before shatting out.

But is the 1.8t flywheel comparable, constructed the same? I ave no idea. They look similar, and have the same sized clutch. We shall see how it holds up I guess. I like to be a little mean to my clutches in a quattro, I might have to be a little nicer to this one.

I think it really depends on that torque....

I think the marshive power pulses vs. a gasser is what matters most. I think a 300 ft/lb TDI would be much harder on it than a 300 ft/lb 1.8t. The pulses are much harsher.

Its all guessing at this point, no idea what kind of power i have or if the flywheel will even last with a stock TDI. I think it will, but I'll let you know in 50k miles

Diesel to gas clutches are the same. There are probably some instances that wont fit, but torque is torque. 300ft/lb is the same whether it's gas or diesel, V8 or I4.

well, the diesel has a much more abrupt power pulse. I think there is a reason there are more DMF failures with TDIs and the 1.8t cars. I understand torque is torque, but the pulse is happening less frequent intervals. Picture someone hitting a little punching bag many times really fast vs. slow hard punches spaced far apart.

There is a different even if the punch is the same magnitude. There is a reason diesel vibrate much more. They can burn fuel all the way through the power stroke, not just the top 15 degrees or so.

Anyways, this is all theory and guessing. Obviously I think this is going to work or I wouldn't have shit out another grand to try it.

It's also the curve, that ahu is making peak torque between 2000 and 3200 rpm.

I got to ride in this thing today, it is pretty awesome.

Gah, so jealous! Nice work Dana! I will have to pick your brain one of these days about doing something similar...

Looks like you've got a B3 TDI buddy in NY! Saw these posted on a 40's in the bag album.

That's Rich's car Oilme...

yes, rich's car is the one that inspired me to build mine.

Shawn and I put in the dual mass and southbend clutch yesterday. Excellent results. Zero gear noise in neutral, and all the scary chatter and resonance at sub-2500rpm is gone. Drives great. The pedal effort is greater, but thats to be expected with a cluch with 100ft/lbs more holding power.

I have discovered another strange running issue, but ran out of time and energy to look into it. Shawn and I were out beating it around and upon a hard start and rip through first and second it stumbled HARD and sort of backfired. The video that shawn posted above captured the major stumble.

Then it had a random miss every once in a while at idle. Otherwise driving fine. I noticed that the miss corresponded to a strange timing value, and after it idled in the shop for a few minutes the stumble was gone 100% and static timing was dead steady again. It seems that a hard pull at full throttle maybe sucks some air from someplace?

I think it might be sucking air somewhere. I need to put some clear fuel line in so I can see if there are bubbles.

[dana]

well....1.8t flywheel cant take the torque in the higher gears. Lame. When you roll on the power in 4th or above in the torque peak you can feel the DMF bottom out. Its not horrible, but its a bummer.It drives so much better, and you can rip through the gears no problem, but roll on it hard below 3k and it shutters. I'm done experimenting. I will just drive it for now and keep sorting other stuff.

[dana]

I got that misfiring issue sorted and advanced the ignition timing a bit more toward where the tuner recommended it. Its a bit toward the advanced side of the normal range.

This thing is a total hoot, I dont know if it was the timing or the cold air tonight or both, but it rips around the dirt roads like a madman. Its a total hooligan machine with that power delivery and a straight pipe.

I can only imagine. Been driving the woman's 6-speed 2010 2.0 TDI Golf Sportwagen around lately; it pulls through the gears in a tidy fashion. The torque can be deceptive at times, and is always addictive.

Similar motor + upgraded turbo + smaller car + quattro = amazeballs

Yea man, I am surprised at how fun such little HP can be. It really does feel similar to my friends 20vt CQ that I was bombing around in recently. I'm sure the coupe is faster, but the TDI feels faster....somehow??

A quick little rip.

In torque we trust

yep, reg'd and insured yesterday. Drove it 35 miles to the alignment shop where it will get aligned today. Its got some hangy trim, some rust spots, some missing interior bits, but it still looks alright.

Drive went with zero issues, cruised there with no issue, and beat on it some. It is LOUD. I need a muffler. I didn't leave a lot of room for a muffler without major exhaust rework. I do think I can squeeze in something like this under the trunk


My alh is fairly reasonable with a straight pipe, but i suppose that tiny turbo quiets it down a lot. This car has WAAAY more bass coming through and no real turbo whistle in the exhaust, so no reason to keep it so loud.

Looks great Dana, my mad dash for Carlisle is still on but still planning on going . Any interest in convoying if your going down 91? I won't have much of a shake down done on my car either, hoping to drive it to work most of the week if I get everything done this weekend.

[chaloux]

An Aero resonator is what I used on my ALH and the 2.5L 5 cylinder. It helps quite a bit with drone... I think I used the AR25 but a larger one might be better.

[scubagli]

Got room to put a noise wave canceling pipe in there?

Hey Ryan,

Shawn and I were planning on picking our way down through the Adirondacks and making a scenic cruise of it, so I don't think we will be hitting 91, but nothing is set in stone yet, what time are you planning on heading? We are planning on Friday morning.

[dana]

I've got about 250 miles on her now. Took it on a small roadtrip up to lake Willoughby in VT this weekend. Of course my odometer stopped working, I think I actually heard the tooth break on the little gear and jam in there. Kind of annoyed, because I wanted to check MPG.

She is running great, been making a few timing and IQ adjustments to get it dialed in. Drives really nice with alignment. Even got to thrash it around sideways up the mountain this morning. Dunlop summers are a bit slippery!

[audifreakjim]

I love the way the car turned out. So very B3. Download MileIQ, it tracks everything you do! Should be just up your alley
