B7 A4 K03 max verified hp

[cmdsm]

What do you guys know about this? The maximum amount pulled out of a B7 K03 and what mods were used?
Thanks

[bhvrdr]

Different dynos will give different numbers and it doesnt necessarily mean the car is making any more power than enother but people will probably say that K03 is good for around 245 to 260hp or so depending on fuel quality, ambients etc. This can be obtained with just a chip.

cheers! Mike

Thanks Mike,
That's pretty much what I have been reading. Some chip manufacturers are claiming 260 crank on 93 octane without the aid of meth. Hard to believe but encouraging. I don't suppose anyone out there has a compressor map for the k03 from a B7?

[gsxtasee]

I don't have compressor map but it is out of breath at just over 5Krpm on our '08 A4 so I assume that, based on my considerable experience with turbocharging, the thing is all hot air at the levels the chips put it at and the stock IC's probably heatsoak very quickly becoming ineffectual.

I would highly recommend a basic pkg of upgrades to include a chip, exhaust, maybe DP/Hi-flow catcon, probably some kind of intake tract work (TIP piping/intake box) and definitely either upgraded SMIC or nice FMIC. This will give maximal use of the airflow put out by the hairdryer as well as improve spool up, decrease pressure drop, and generally improve efficiency of the entire system.

Thanks for the info. What kind of air flow (lbs/min.) are you getting on your '08? Do you know at what power levels (air flow, hp, etc...) the fuel system needs attention? How about the stock internals of the B7 A4? What are they rated or assumed to be reliable to? Any idea what the stock clutch can handle?
Thanks

I respect the fact that you are trying to help out people, but from my knowledge of our engines (2.0T) what you are saying simply isn't true. The compressor map does not determine how much power a turbo will output, only at what point is it most efficient to run at. You can run turbos well out of their max efficiency range and still make good power, with minimal negative effects.

The stock turbo is very small and does not make great power up top, but to say that a chip runs the turbo so hot that it makes it ineffectual is flat out wrong. Maybe during the days of the B6 with its single SMIC this could be true, but with the B7 and its twin SMIC's I have personally not experienced heatsoak at all, and for what its worth have not seen a single thread on here about it. While its true a FMIC would probably lower the intake temps and therefore theoretically yield more power, it would also create more lag as there is more tubing to pressurize. The fact is that not one single person has ever dyno'd this engine with and without the FMIC back to back. To say that it would help is like saying the Carbonio makes power.

Also its been proven that at moderate power levels (chip + supporting mods) that the cat is not restrictive. See the thread titled "Chip Vs Test Pipe" for dynographs.

max with bolt-ons/chip 300 flywheel

max with bolt-ons/chip 300 flywheel

Cool, what sort of bolt-ons though. Chip (from who), intake, full exhaust (w/ or w/out cat), on Meth/Race...?

To get somewhere close to 300chp you would absolutely need the upgraded fuel pump after the chip, then you'd need 100 octane program and fuel, testpipe, exhaust, likely better intercooling or a very cold day, and STOCK intake. Then you can probably touch 290hp or 300. This is assuming you're not using optimisitc dyno numbers to think you are getting high crank numbers.

What is krisstokes putting down at the crank. His sig says 260awhp.

I think 300 is not that hard. Hell I put down 255chp with just a chip on a very low Dyno Dynamics machine when it was 90+ and very humid. I would say when I went through a few tanks of 100 octane I easily had another 20hp avail. The 100 octane was very nice. So I was about 270-280 with the 100 and thats no intake, exhaust, test pipe, fuel pump, etc.

True, but keep in mind that is HIS DYNO and not comparable to anyone elses. To put it in context, he ran a 13.7x with a 1.8x launch (got a great launch) with a trap of 99mph. That's fast. It was chipped, testpipe, and exhaust.

But, on the other hand, Angelo who has ONLY a chip on his car ran a 13.9x with a worse launch of 1.9x and a trap of 97mph. Not as huge of a difference when you look at it that way.

That's by no means taking away from what kris did which is make the best run we have on a k03. It does illustrate that people are kidding themselves if they think all these bolt-on are doing much more for them until they addresse the fuel sytem.

According to this link (http://www.audi-info.com/2007/03/giac-audi-a4-b7-20t-flashloader-chip.html), different A4 B7's have different fuel pumps (read about halfway down). If we have the newer pump in the car is it necessary to upgrade the pump when using the K03 with race gas or Meth?

[chrislane31]

I know you can't compare different dynos, but 260awhp is certainly over 300chp and without the fuel pump upgrade.

never seen that link before... interesting info.

I haven't actually checked to see which pump I have. Obviously hoping for the newer one but not sure how it will affect my plans one way or another.

You got a dyno sheet of your 255chp Dyno Dynamics run? I would absolutely love to see it.

And I don't believe there are different fuel pumps, just different FPR's. I think the 2005.5 got the weaker one (NOT AS MUCH PSI). APR's programs factor this in but has the same program for any fpr.

[Tgr_Clw]

It's in shootout mode.

You have the one that shows whp/wtq?

Or at least something that the conversion was based on?

Perfection. That's the one I wanted. Huge thanks.

[Tgr_Clw]

Wouldn't happen to have a baseline i.e. when your car was stock on the same dyno would you?

[bhvrdr]

The fuel pumps have been superceeded FOUR times now. There were B pumps, F pumps, H pumps, and now J pumps.

The information that was put out by GIAC last year about needing an "F pump" was bullsh1t information. I think it was wishful thinking on their behalf but they didnt do their homework. APR had the actual specs from hitachi and the output on the pumps is the same. In fact the F pump has been superceeded twice itself. No big deal but as long as your pump is functioning it does not need to be changed out. There are just as many cars with way old original B pumps making as much or more power then brand new 2008 cars with J pumps.

cheers! Mike

[chrislane31]

No baseline dynos sorry.
