Haldex HPP info to pour over for you folks who like graphs and such.

[rabbitgtibbar]

Just got my aluminum finish HPP from EIP. Here's is a scan of the first page of the instructions that came from Haldex. Do with it what you will.

I'm linking it because I'm leaving it full sized, so you guys can plot and interpret to your hearts' desire.

EDIT - I, of course, meant pore over.

how true, fuel for the friday fire

Thanks for the info. It looks like it doubles the tourqe at the rear wheels in the given example and brought it on much quicker.

[BassMan097]

Its amazing how a picture is worth a million words. Thats the best explanation of the haldex system i've seen yet. More torque to the rear wheels and its gets there faster than stock. Thanks for the graph

Lucky bastard!
I want mine damnit!

I just noticed the box has a label that reads:

Street version

I wonder...is there a "Track version"? Hmmmm...

[TMcNally]

8 big ones huh...jeez...

[Mr Johann Vegas]

Hey, can we get a pic of the aluminized finish? PLEEEEEEEEEEEEEEEZE?

I always though "big ones" = $1000.

Ok 8 medium sized ones and worth it a twice the price

Actually, if I remember correctly, there is a version that locks up during heavy braking also, that may be the race version....its on the website somewhere, I'll look it up.

Though, I'm curious what the advantage of that would be?

[Daemon42]

Just in case it isn't obvious given that those two graphs are on different vertical scales, here's one overlayed on the other.

How many words is that picture worth?

It is a bit weird that one graph spans 14 seconds and the other 15,
because other than that the engine torque curves overlay on top of
each other almost *exactly*. So much so, I left it out of
the comparison.

My new favorite number:

Eleventy billion.

/Actually it took me a minute to notice that, too. I thought, "Great, it comes on sooner." Then, I realized it comes on sooner and stronger.

They both span 7 seconds. One from 8-15, the other 7-14.

Ah there we go. Knew I was missing something.
Saw 14 tick marks and never bothered to look at the left side of the scale.

EIP has some aluminum finish ones left, and plenty of blue ones, AFAIK.

[Daemon42]

I've been looking at that comparison.. thinking.. "Wow, that's really
dramatic.. but it doesn't *feel* like twice the torque transfer of stock."

But it occurs to me now, that that graph was made at an earlier
time for a different car, probably the Volvo S60, and I suspect that
the difference between stock and HPP is not as great for the R32. The
Haldex programming in the earlier Audi TT's and I suspect the Volvo
is less aggressive than it is for the TT3.2 and R32. Folks can feel the
difference on the road, and see it react differently on an AWD dyno.
Even a stock R32 Haldex ECU should represent an upgrade to an older
TT225q. My suspicion is that the stock R32's torque transfer curve
looks a lot like the stock one above, but with a considerably higher
torque transfer limit.

I spoke with EIP this morning and put down $$$ for mine--oh yes. They said they have only a few of the silver-finish ones left. Good luck to those in the hunt.

Nah... That would be "bigguns."

Perhaps the stock R32 torque transfer curve would fall somewhere in the middle of the two overlayed curves above?

QBNR32 has my car currently and drove my car yesterday in the wet... needless to say, he was VERY impressed with the car.

Why would you not want the blue ones? We have blue break callipers, springs, etc. and at least my car is blue, so the HPP, if I had the money to spend on it, would of course be blue.
What's the point of it being alluminum? To try to fool the dealer into thinking the car wasn't modded?

Bingo.

[BLUL8N]

How's the gas mileage been affected by those who got the HPP?

I asked this before, but no answers, which makes me wonder if you now go to the gas station twice as often

Ronald

[rabbitgtibbar]

I'll let you know after I install it. Right now I only average about 290/tank.

[Daemon42]

Depends entirely on how you drive.
Mash on the gas a lot, and mileage will be less than stock.
Cruising on the highway it's no different than stock.

It seems like I recall reading somewhere long ago that the Haldex programming for the R32 was indeed more aggressive than previous Audi TTs...possibly in an early European review of the R32 or even the TT 3.2 DSG?

Oh yeah like the dealer is going to know that the haldex ecu is supposed to be finished aluminum and not blue, they have worked on so many R32 haldex ECUs before

[rabbitgtibbar]

They cost the same, so why risk it?

And I'm sure it'll blend right in with all the other blue parts on
the bottom of the car.

Risk what? I don't get it, is your car borrowed?

Risk any of the BS dealers might give for having "performance enhancing parts on your car."

[hingedthinker]

uh why does it matter what color the parts are where you nor anyone else will ever see them. Save the money and get your head checked instead.
