Yeah its pretty sweet. Even in the chipped Passat, the power difference is large.

And man-o-man are my brakes better in the TDI

Hmm, thought this was a thread about the dynos run at TDI Fest?

Seriously, that looks like a strong car with a nice curve but does not compare to the results in Lexington last Saturday in any way. Comparing your mods (listed in your sig) to mine: I have more turbo, more injector, more cam and some head work. I don't think you would have spun 186WHP on that dyno!

Heartbreak Dyno!...

Well my dyno was on the same weekend! And both were eddy-current type dynos, so its not like I did 186 whp a Dynojet (inertia-based dyno). On a DJ that would be like 208 whp.

True its a *not* direct comparison, but the dyno's should be within a small percentage of each other. Haters gon' hate

Keep in mind the TDI manual transmissions have a double overdrive, meaning 4th gear is not 1 to 1, perhaps throwing off the equipment.

Also, if they are calculating the torque tire diameter is not published diameter, but actual diameter with weight on the car.

4th is 0.98:1. (for the 5-speeds)

Yeah, and dreamers gon' dream...

No wonder dyno results become so contentious. Only way to get reasonable correlation is to run the same dyno on the same day. We did that at TDI Fest, and you were not there. Your effort to try and create some kind of correlation with the result from that day to boost your ego is a little sad.

Give me a break bro. Just having some fun here. Show me some track times and we can compare there

I think Chris's dyno provides a helpful comparison. I don't know if it was the operator, the weather, correction, or something else, but I've seen a lot of TDI dynos and these are universally low enough to really not be useful, IMHO. I agree with A5INKY that dynos are most useful as back-to-back comparisons, but the numbers I saw from the Fest were way, way off. Someone should figure out why.

No worries here. I just raced my first autocross today, awesome fun. Biggest problem was trying to stay hooked up, my car will break traction in 3rd gear even with a Wavetrack and pretty gummy tires!

Honestly 178/285 at that dyno was pretty disappointing, but it is what it is. It was enough to take the trophy for "Highest Horsepower" that day. Not a number to brag with here though, so I won't. I am thinking I would be well north of 200HP on most other dynos.

I have not had it to a 1/4 mile track yet but am interested in finding an opportunity. Will not hesitate to post when I do.

You have a lighter car, but I would line up with you anytime.

It really is a nice curve you posted.

AutoX in a TDI would be a lot of fun! I am waiting till I get my suspension all finished before I try it.

There is no doubt that your car should make more power than mine A5, none at all. I was pretty happy with my little 17/22 results and just wanted to share.

I found autocrossing frustrating, although I only did it a few times. Lots of courses require a 1-2 shift in the TDI where other cars don't have to, which hurts times. Getting hooked up is a challenge as others have mentioned. But what I didn't like was standing around for 8 hours for about 4 minutes of drive time. Track days are a lot more fun, IMO.

I got out of 1st right off the line and drove the entire course in 2nd. It was revved out in the wider sweepers but no room for 3rd. The longest straight was into the finish and 2nd was really spinning. I actually grabbed 3rd on my last lap and had my best time of the day. What I really needed was a 2.25 gear. Also have to say that my laps got faster as I learned to stay off the go pedal enough to allow the tires to grip, otherwise it was full drifting from corner to corner.

I will have to find a track to play at, more seat time than autoX would be good.
