Went to the Dyno today

[apexslider]

1.8TQ GTRS elim kit equipped, South Bend clutch, apr exhaust, and pump gas....226awhp and 252tq at 25.3psi. I was hoping for more, but it knocked at higher boost so that's the best I could get. This was on a Mustang Dyno. As soon as I get my camera charged I'll try and post the graph

[F16HTON]

Prolly would have had 20-30 more HP at 22psi (lower egts = more timing)

[RLB6]

That seems a bit low. Like Greg said, lower the boost and increase the timing will yield more power.

[apexslider]

our first run was at 21.7psi and we only got 220hp and 247tq. Either way, the numbers suck. I'm really disappointed

[absolutegtr]

Why is this?

I plan to go GTRS...but it seems like dropping close to $3K just simply isnt worth it

[apexslider]

that's my question. I'm going to do a leak down and compression test to see if that tells me anything. As of now I'm praying the motor has some issues becasue those numbers are NOT worth the 3200 I paid and the hassle Eurocode put me through

[dirtybrd]

You can't just slap it on and expect #s like Gregs. I'm sure he set the boost and timing, logged, dynoed and then adusted, logged, dynoed, so on and so forth. They're not plug and play for max. power, you have the adjust the settings, more boost less timing, or more timing less boost, etc.

[A4ringedONE8T]

Thats for sure way low, good luck finding the issue!

[converted2audi]

is that with the Revo BT file? Im getting ready to put the gtrs kit on my car in the next month or two.....have mostly everything i need! Have to do my timing belt first though....

What are the rest of the components of your kit? FMIC? You said its the elim kit, so you are still running the oem manifold? Test pipe or hfc? Those things will all make a difference in your numbers too.....a straight eliminator kit isnt going to put up Greg's numbers.....

[apexslider]

I wasn't expecting anything close to greg's numbers...not sure where that came from. I was thinking 250awhp.

I'm running REVO's BT file, atp's high flow stock manifold, 3" test pipe, awe fmic, and full exhaust. So it's not just the kit, there are some supporting mods to help.

[AudiA4Turbo22]

^^ try using my VAC LEAK guide from my new post it has part #'s and everything!

[dirtybrd]

Sounds like you need to play with the setting. Do you have a SPS and Vagcom?

[apexslider]

I have access to both. I've got the SPS3 sitting in my glove box, but I'm not really understanding how it works. I've got a mbc so doesn't that leave the sps useless unless I'm changing to a higher octane file? As for vagcom, I need to learn how to log so I can get more detailed info posted, like those spread sheets I see.

[dirtybrd]

Read how to set it and set your boost to 9 and your timing to 5 and see how it feels. When the ECUs are flashed I think they are set @ B6T3 which would explain you low numbers. You still want the ECU to see B9 even though you're using a MBC.

[F16HTON]

You should have seen 250AWHP easily. I will explain to you how the SPS works for you.

There are two knobs on it with 10 settings each (0-9)

If you are running a MBC or EBC you want the boost setting to be on "9", with this setting the ECM is requesting 2540 mBar of boost at all times. (Mode 3, Setting 9)

It you are using pump gas (91-93 octane) you want to set the timing to 3-5. (Mode 5, Setting 3-5)

If you were running 23-25 pounds of boost with the MBC and did not have the SPS 3 set to boost 9, you were killing your power, (the ECU was seeing overboost and was pulling timing like crazy)

Here is a copy of the user guide for the SPS3 http://www.revotechnik.com/products/...Guide_V2.3.pdf

[apexslider]

that would explain a lot...I was reading the instructions in the box with the sps, but it wasn't to informative. I'll go out and change the settings and see what I think.

Thanks again for the above, makes me feel much better.

[dirtybrd]

Also don't forget to turn the boost down to about 20psi to start with. But you can't forget to run some logs. Just because it feels good doesn't mean its safe, that goes for cars and sex.

Anytime you need help, feel free to ask...

You may not notice the differnce when you are driving, unless you are in a high load situation, the ECM only pulls back the timing when it needs to.

This is most likely what happened in your situation...ECM saw overboost based upong the MAP requested (Boost 6) and tried to close the throttle plate (this is overidden though) so it began to add fuel to keep the A/F safe and the EGT's wen through the roof. Once the EGT's were to high, it began pulling timing.

The end result was less than the 250AWHP you should have seen.

Three key rules for dynoing your car.

1.) Fresh Plugs

2.) Race Gas

3.) Log the first pull, watch the A/F and Timing, be ready to abort mission if necessary.

The dyno operators (Dicks) are usually in a hurry to get you on the dyno and get you off the dyno, haste makes waste, it is not their car they are damaging.

You can bet your ass too that if you toss a rod, they will make YOU clean up the mess

[RLB6]

Yeah, I'd be disappointing too. On my base run with my 71R elim with only like 17 - 18 PSI (SPS settings: T2, B6), I put down like 243+ awhp. That's on a auto tranny AND stock cat

our first run was at 21.7psi and we only got 220hp and 247tq. Either way, the numbers suck. I'm really disappointed

How much psi is the pre-set setting of boost 6 supposed to see?

[apexslider]

already done, turned it down to that for the last pull.

thanks for rubbing it in

There is no exact "pre-setting" it is all based upon duty cycle and your wastegate if you are running the N75

Have you ran on this dyno before or has anyone else you know run on it so you can compare your #'s to them? Because you cant compare your #'s to someone elses that ran on a different dyno.

3125 lbs for a B6 1.8t quattro tiptronic and driver? How did you come up with that weight or was the driver a negative 500 lbs? You do know that putting in the wrong weight will mean the #'s the dyno plots out are going to be wrong?


Stock 2002 B6 1.8t quattro tiptronic curb weight is 3550 lbs, so even with a avg person in the driver seat will be over 3700 lbs. So as you can see your 3125 is way off.

This point was argued when it first happened and since I wasn't allowed back in the dynoroom, I was not able to correct this. It's spilled milk now.


BTW, it wouldn't be that way off but you're right, it is off. Had the correct weight info be inputed, then my numbers would have been higher

So True my friend!

You should never be running 25psi on pump gas first off, one thing people need to learn is more boost doesnt always mean more power. Having alot of boost and no timing isnt worth shit. And like the others have already informed you, turn that Boost to 9 with the sps then set the mbc accordingly. I would personally run the boost at 22psi and the timing at 5 and I guarantee you would have made 250whp unless your car has a problem.

[ladedruck]

I am not at my dyno computer but I think the hp@50mph is wrong also. I don't remember seeing an Audi less then 10 ever especially a quattro. The specs come from Mustang. I will check mine tomorrow.

We went from 21psi to 25+ with a little tap of the mbc. That high of boost was not intentional. I'm fully aware of limits on pump gas. I used the sps today and it actually did crisp the power up some. I dont have my boost gauge yet but it should be around 20psi. I'll be able to keep better track once my podi gets here.

I'm going back to the dyno here in the next week or so after we make some changes. I'm hoping for better numbers next time

[A4 TSCHUSS]

I had 13hp at 50mph on one dyno and at a different dyno (different facility) I had 12.7 on 2 different runs

[A4 TSCHUSS]

do you have VAG COM? If so then go do a log in 3rd gear while logging block 115 and it will show you requested boost in 1st column then actual boost in the 2nd column. You will have to convert it from the BAR it is shown in to PSI after also subtracting 1000 from the number if you are at or near sea level.
actual requested
Ex. 2400 2350

2350-1000=1350 or 1.35 bar which is 19 psi (google a bar to psi conversion table or calculator to find out the exact conversion). By doing what I just showed you, you can see exactly what you are running.

Sorry i meant that is a number that the mustang company provides. the operator has to input it for each car. I would think 12.7 sounds better. I will try and look at the list tomorrow.

good to know, great to know actually. I'll get some numbers and post up. Any one know a good "how to" guide for lemmiwinks?

[ladedruck]

the mustang dyno settings should be 12.7hp@50mph and 3875 for the weight.

You have PM

[dougyfresh]

Does that help set the rollers correctly? Which will affect the power/torque results.
