6 speed swap in to my TDI Golf 4

[dremd]

Nice COcyclist.
I hope that I can get around to aeromods once it cools off.

I did a 400 mile round trip this weekend, I haven't refueled yet (still over 1/2 tank indicated) I hit a ton of traffic on the way out (5 hours to cover 130 miles) so that isn' going to help Had the a/c cranked the entire time (It is hot down here).

How's it going?
I noticed that the last fuel log entry is from two years ago. Will you continue updating it, or start a new car in the garage for the six speed (that's what Basjoos did after swapping the Aerocivic's engine)?

[dremd]

Probably not, I so rarely fuel from commercial sources + my driving has absolutely no routine so the data is fairly fu bar.

However I'll share my miles to low fuel light.
890
716 (tank mentioned above)
805 (I had 2 flats during this tank + some towing)

As mentioned elsewhere, I now drive as fast as I think I can get away with but using as many eco-driving tricks as possible.

How does that compare to before?

Thanks,

About the same, but a few other things have messed with th data.
1) my old max (short of emergency) crusing speed was 65 and is now 80.
2) I added 100 lbs of sound deadning about 1000 miles after the 6 speed.
3) my fuel is not super consistent
4) I changed timing belt + cleaned my intake about 1.5 tanks before the 6 speed.

Wow 80MPH cruising speed, that's insane!

Nice quiet ride now while driving down the hiway? 100lbs, what did you use? It seems to me that little bit of wieght for a diesel shouldn't make that much of a difference in overall mpg's & performance.

Fuel is not consistent? Using bio blends, or just different fueling stations?

thanks for the quick reply,
Dave

Throughly insane, I'm certain that I could improve mileage significantly by slowing down, but i am satisfied with 50 mpg ish on low carbon $3.00 a gallon BioDiesel.

According to Db meter on my iphone while placed on my right shoulder while cruising at 70 mph with A/C radio etc etc off (not super accurate, but good for comparisons)

Initial reading 96~98 Db (didn't seem that loud, but it wore down on me with longer trips and made me crank the radio louder than I ould have liked

6 speed swap 89~91 Db Very dramatic improvement but note that I also upgraded from Single mass flywheel to Dual mass flywheel, tightened up a lot of random things in the engine bay biggest of which was vibrating turbo support bracket.

SoundDeadner on Floor + hatch only 84~87 Db Biggest thing I noticed was how LOUD all of the rattles on the doors/ sunroof are. Basically this lowered the noise floor down below the sound of the rattles which is HIGLY aggravating.

I used a few CLD (Constrained Layer Dampener) Tiles (10?) mostly around my Subwoofer, a Bunch of CCF (closed cell foam) mainly 1/4" but some 1/8" in odd places and the Main event a Roll of MLV (Mass Loaded Vinyl) the only way to genuinely reduce noise in a car (CLD just does resonance, nothing else) + new rubber backed carpet. Everything but the Carpet cam from Dan at Sound Deadener Showdown - Your Source for Sound Deadening Products and Information . Don is THE MAN as far as all of this stuff just fantastic service, easy to deal with no complaints.

I would like to do the Doors, but time is at a premium lately. I would expect my Golf to get down in to the near luxury zone of Sub 80Db. For reference my friends LS 400 measures in the 80~82 Db range.

The biggest thing I noticed with the weight is that it is easier to bottom out the front suspension coming off of a bridge by a friends house.

I Run BioDiesel made by a local guy with multiple feedstock sources. drum to drum there are noticeable (all be it slight) differences in power/ range/ smoothness.

That's what Iphones are for :-)
Hope that info helps someone out!

[Dave's Civic Duty]

Sure! Thanks for sharing the secrets of one that has done lots of work on their Golf. 50 MPG & biodiesel that's what I want to be able to do. So your using straight bio, no blend?

I'm sure you'll get all of the squeeks worked out. I didn't think about putting down a noise barrier to only hear more rattles, that would sort of suck. So now I understand why I'm so tired after driving for hours in my cars, it's the noise. I'm a musician, & it's that noise too!

Great post,
Dave

I run B99. why b99 and not b100?
My supplier gets a 0.99/ halon tax break for b99 and no tax break for b100 or atleadt that is what he tells me.
When it got cold last year I just ran 100% petro because I was busy and didn't have time to figure it all out.

The rattles are improving, at this point what I need is a hand from someone who doesn't think I'm nuts to drive while I hunt rattles.

[Dave's Civic Duty]

B99, cool! Tax credit for BD, excellent. I was going to try & secret squirrel it, no bio d stickers. I know the smell gives it away. For a while in some places they were checking so they could collect on the road tax money.

I'd love to drive your VDub while you checked for rattles, too bad we live so far from each other. In fact, I've never drove or ridden in a TDI. But i know I'd love to have one around the '98 to 02 vintage. Bug, Jetta, or a 2 door Golf w/ a 5speed. Not only for the dependability but because I love to shift!

Thanks,
Dave
