New Addition Audi A4 3.0 V6 6-speed M/T Dyno & progress thread

Wutup peoples i recently sold my Acura TL and thought i would try my hand at German engineering so here goes.
I purchased this Audi A4 V6 3.0 6-speed about 1 week ago and i must say it is a very nice car with lots of potential. It has a clean title and 140k miles. I live in miami and this car was a Boston car for all of its life the owner drove down here to live and sold it to me recently. It has alot of rust underneath the car but i am slowly alleviating all of the oxidation and grime from the car as to me this is the only way to learn by taking apart cleaning and putting things back together. Ok on to the fun stuff.

Nice but 140k miles is a hell of alot of miles for an AUDI. They aren't very good high mileage cars. But I hope it works out for you

ye i hope so too but i wntd to buy a high mileage car so i know what to expect when i buy my next Audi, have you ever owned an Audi? i am trying to learn wut owners and mechanic shops say about these cars so i can get a better idea of what im dealing with so i can either learn what repairs might come up in the future or if i cant handle it scrap the whole German thing all together idk really just gathering knowledge at this point, the only thing ive herd from the local mechanic is there are unusual electrical failures like fuses and relays....doesnt sound to painful as of yet lol

None turbo right?

I had 2 friends with stock A4 turbo, and after about 40k their gaskets started going bad, electrical problems and motor mounts started going. I guess it you keep up with maintenance like any car it should last.

been awhile since i updated but heres some new stuff,

ok i decided to re-do the exhaust becuz it was too loud and i had to add another muffler. I basically decided to not buy a separate y-pipe and muffler so i just decided to put on a muffler that would act like a collector, a dual in single out. Anyhow this is exhaust setup Version 2! And i will probably change it in the future.

I have gone to this shop before and this guy is a one man show with all the fabrication tools and skill necessary to build a quality exhaust. Sometimes i get so disappointed in myself for trying to deviate from a higher standard just to try and save some money. Lets jus conclude that i wont be using neone else for exhaust work.I even managed to get a TIG welded piece done. This exhaust allows me to switch the catalytic converter in and out with slip fit connections that the shop owner fabricates in house. Ill let the pics speak for themselves.

Also managed to get a take off vid of this new exhaust.

finally finished guttin the cats, it was significantly easier this time, i learned that u jus get a huge drill bit and go to town on that sukr then just start yankin pieces out, i cut this thing in half which was the best idea





took a little better pic today of the overall car

Finally managed to get to the dyno last night had to drive through an hour of traffic! Nehow i am super satisfied with the results which i had an idea of what the improvements might be but putting actual numbers to it was just all the sweeter. So the results were a bit misleading as far as the torque numbers go. Here is a screenshot of the stock torque vs the new torque numbers: There was a large drop in torque as much as 30. Now if you remember i did remove the actuator in the variable intake manifold system. This was a definitive comparison that you will lose alot of torque if you remove it but i wont be replacing this actuator due to the substandard quality of plastic used and the fact that they will become brittle and could ultimately damage my engine. So you guys are on your own their good luck with that. However.... i noticed from my 1/8th mile run that i launch @ 4000RPMs and drop to ~3100RPM's and quickly accelerate through the powerband to redline and on the 1-2 shift i drop to ~4200RPMs and on the 2-3 shift i drop to ~ 4600RPMS. I also noticed i didnt rev all the way to redline becuz well the car didnt want to becuz it was choked off. What does this mean? Well i havent been back to the 1/8th mile yet with my latest setup seen here however in theory the loss of 30awtq is kind of irrelevant becuz i am only in that specific power range for a very short time as i quickly accelerate through that range and i am now using the upper RPMs as the speed increases so the loss of torque becomes less and less noticeable.




This is a screenshot of the areas of the curve that will be used on the upshift, you can see the area between 60MPH and 70MPH (Equals 4000RPM - 5000RPM) that the torque peaks in this area and will be more "usuable" on the acceleration than the stock peak torque curve becuz you drop into this area on the upshift. Something you never see when you torque peaks at a very low RPM. Sure it feels good for daily driving but when you put the hammer down its another story....




This is one of my favorite screenshots (obviously lol), this shows the biggest increase in AWHP 179 vs 154 but not only that if you notice the "area under" the peak HP curve the gain in torque under the curve is ~21, 152 vs 131.




And finally the video for proof! lol it wasnt my best run but you get the idea that the gains are there

OK so basically in a nutshell i gutted the trunk and scraped all the tar off of the car. And then i converted the car to FWD! This alone netted me 10whp/10wtq and a 100lbs loss of weight. (about 70lbs of that was rotational mass)

See pics and vids below. The picture of the digital scale was the weight without driver and a 1/4 tank of gas.
