nice way to start the thread, good work.

[Sal_B7]

good stuff!! Im sure soon enough we will be seeing some GT30 dyno's along with some 100 oct. GT28. Cant wait for those to pop up!

[colt45]

great thread.

[agkellyboy]

With GIAC 93, AWE FMIC, AWE HPFP, AWE Exhaust, and 034 HFC I did 238whp and 288wtq on one of those Dyno-to-Go things

[jimrobbington]

REVO stage 2, test pipe, full exhaust, stock intercoolers, stock fuel pump, 100 oct tune and gas, mid 80 degrees ambient temperature.
First run was ruined, this was the best dyno off of my actual second run. Each subsequent run lost about 10 HP from heat soak, so I feel that my first cold run would have been at least 5-10 hp higher. 201 WHP, 258 WTQ

[eskimopunk]

Tip, VMR TP, Uni Stg 2, custom intake, 91/100 mix. 180 awhp, 234 awtq. My third run was 10 hp better, I'll scan the dyno sheet sometime soon.
Mustang dyno, 2000+ ft above sea level, 90+ degrees.




And just for fun - Highest HP ever recorded for an A4 - skip to 2.20 for the run:

[Sal_B7]

^^ha ha that was awesome!!! Congrats on the highest HP B7 A4!! No one can touch you!!

[Great White]

Good job guys. I'm going to dyno the shark once I get the new mods on.

[wootwoot]

Updated with a few vendor dynos.

Haven't there been arguments about the APR dynos? I'm pretty sure I was in one of those lol. I think you should wait for customer's personal dyno sheet. Imo

Thats why I put them at the end and said "Vendor Dynos". I can look at how to accentuate the fact they are vendor dynos or we could create a new thread for vendor dynos. Thoughts?

[eskimopunk]

Nah makes sense. Maybe make the type a little bigger or bolder or something. ?

[wootwoot]

[swoardrider]

Nothing special on the HP side, justing posting to show that some of the earlier B7 ECUs don't like to be flashed. Notice the "dip" at higher rpms in the APR 91oct file that is not present on the stock file. I believe Quattrosaint had this problem too, but with a GIAC flash. He ended up getting a custom tune to get rid of the "dip".

At Wheel (quattro) chart:

[eskimopunk]

^ Nice, might want to mention in the post and not the edit section that it's awhp.

[ZimbutheMonkey]

Hmm, so if I do the math on the 3.2 dyno that means that at an ideal 255 CHP at sea level, if we take an average of 215 AWHP, the corrected driveline loss is 17%. If it was taken at elevation then the percent loss gets even smaller. Wow, maybe I should tell this to all the guys who go to the dyno with a BAT setup and try and apply a 25% correction factor because they're butthurt about not getting the numbers that they wanted. But ahh, but what do I know.

[gearhead1186]

best to calculate DTL with mustang dyno results.. dynojets read high.

You do know 17% DTL is a crack smoking pipe dream right?

A man well versed in the operations of a dyno once said: "Give me control of the dyno and I can make any car have any hp you want". In other words, don't trust dynos. Take it to the street/track. How you put it to the ground is all that matters anyway.

[Coderedpl]

I should have my info within a week or so. Going to a dyno this coming weekend. Stage 2 tiptronic

[Der Konig]

Is the apr 2.0t 93 quattro a manual or tip?

[GarrettReid]

I think this is appropriate.

[Coderedpl]

Here is mine from today:

2006 Audi A4 2.0T Quattro Tiptronic
• REVO Stage 2
• 3” Custom Testpipe and downpipe
• 3” AWE Dual Tip Exhaust (from mid-pipe back)
• OEM Diverter Valve
• Carbonio Intake
• Tank up using BP @ 93

I have a leak in my flexpipe section of the exhaust, not major, but i do I'm not sure if that would have a huge effect





The first run I was told I made 208 but they didnt count it since car kicked down too early or something. Funny thing is, that was the best run lol. So going by all these numbers its about 203-204 to the wheels. At least I'm not in 100 something haha but damn i want moarrr powaa now!

[BigRedAEM]

Any idea of what your're making at the crank? When I get my 034 High Flow Cat installed we will be very similar.

[Coderedpl]

I would say about 255 judging by 20% drivetrain loss of a tiptronic if i'm not mistaken

[B72.0T]

Putting mine on the dyno Saturday.

[Teeguzi]

Car specs in sig. I wasn't super thrilled with boost performance, but not bad overall with stock cat and fuel pump.

234.0 AWHP and 249.9 AWTQ on 91 octane @ 68 degrees F.

[wootwoot]

A few more vendor dynos added. Would love to see some stage 2+ dynos if anyone has some available.

[Operator]

Interesting read I found on the different dyno options out there.

I got these from the shop that is about to dyno my M Coupe. It is consistent with what I have been told elsewhere but certainly an interesting read:

20) My car makes 300 hp but your dyno says it makes 215. What is up? Our dyno is the most accurate measurement of torque at the wheels. More accurate than most. No "interpolation" or "estimation" or "inertia factors" are applied like they are on other competitors' lesser machines. What this means is that this is the actual torque being applied at the tire. Typically, a 300hp all wheel drive car will measure in around 210-215 on our dyno. This is normal.

21) I went to a Mustang dyno and they said theirs reads low, but you say yours reads low. Is this just some trick used by tuners? The Dyno Dynamics is known throughout the industry as being the "heartbreaker" dyno - because it breaks the heart of every man that thinks he has 500 hp when he really has 350. The Dyno Dynamics reads lower than the Mustang. It reads WAY lower than a Dynojet. It reads WAY lower than a Dynapack (which actually reads too high on tip-in). The closest in numbers (at low HP) is the mustang, but using the above example, the same 300hp car was dyno'd back to back on a Dyno Dynamics 450 LowBoy (what we have) and a Mustang AWD500E (what some other guys have), and that 300hp rated car consistently read 223 on the Dyno Dynam ics and 249 on the Mustang. One hour apart, exact same car, same town, same altitude, etc.

22) Why dont you just make your numbers look high to be the same as some others? Dyno correction is not a fixed amount. In other words, adding 30% at xx RPM and xx power does not translate. i.e. Using the above example, a car that makes 225 is about 1.3 to get 300. A 900hp car on this dyno is NOT making 1200hp ! Dyno numbers should be used for relative back to back comparison, and nothing else.

23) How do I compare my dyno results to others with similar setups? For Subaru owners, there are enough internet resources to compare, but essentially, Dyno Dynamics and Dynapack are the only 'consistent' numbers, and Dynapack reads very high, Dyno Dynamics very low. We can help you seek out other similar results. A great resource listing a slew of Dyno Dynamics HP baselines is available in the Gallery section at the KTR Performance Dyno Gallery Web Site. It should be noted that KTR uses atmospheric correction, which we do not use on our dyno plots.

24) How do I compare my pulls to Mustang Dyno, or a Dynojet, or a Dynapack? Every dyno is different. If you want dynojet or mustang-ish #s you have to multiply by 1.18 or so, 1.25+ for DynaPack. But remember, this is just ballpark, as it is not linear.

Oddly enough this shows a DD higher than a Mustang: http://www.modified.com/tech/modp-09...son/index.html

[ladedruck]

I have never gotten to compare our Mustang directly in AWD mode to other brands (because there are no other working AWD dynos in our area.) but we had a FWD vr6 turbo jetta make around 315hp on ours and then he went to a local dynojet the next day and made 351hp with no changes to the car.

NIce.

New Dyno done today! And yes, these numbers are at the WHEELS!

[jerseybrian]

congrats breaking the 300wtrq mark Jim!

[BigRedAEM]

What changes did you do to get the extra 50WTQ and 20WHP in the earlier graph you posted? I realize that different conditions will give different numbers but what parts of the car did you change?

[jimrobbington]

congrats breaking the 300wtrq mark Jim!

Thank you! Thank you! Now I just need to get that HP up. Except my wife will leave me if I don't stop (for now). She thinks having a baby is more important that reaching 300 whp. boo. (We're not pregnant yet, she just wants to be.)

What changes did you do to get the extra 50WTQ and 20WHP in the earlier graph you posted? I realize that different conditions will give different numbers but what parts of the car did you change?

The things that I have done that I completely believe are directly related to better performance are this:

I replaced the dv, replaced a bad N80 valve, adjusted the wastegate, upgraded to BKR7E copper plugs, erased stored logs on the car, and turned the boost up a notch on my REVO.

[CorneliusRox]

So stasis is 257 awhp with their big turbo kit, while jimrobbington is pushing 220awhp with a K03 (correct?)?

220awhp sounds about right to me, but for big turbo, I thought most guys were past 300awhp?
This thread has successfully confused me :-)

No, you are completely right, Corey. 257 whp is definately low for a bt. I mean, vizi is working on 400whp, iirc. I mean, operator's K0R, was at 255whp, and we think there was more tuning/improvement, to be proven this thursday by another dyno. I hope to get up to 250 whp with full stage 2+, hpfp, check valve, meth and maybe fmic.

Here is the Audi A4 Quattro I just tuned and put on the dyno, not too bad for AWD and WHP. Comes out to be around 270bhp and 305 ft-lbs if you give it around 20% drive train loss for the AWD. Very fast and fun car to drive, quite a change from the Saabs I usually tune :-) JZW
