I love REVO and cold air! (Dyno Content)

[jimrobbington]

Wonderful trip to the Dynocologist this morning at 8. Couldn't have planned it better. First thing in the morning of our first frost. Ambient temperature ~38 deg.

I wanted to get a new dyno as a final stage 2 baseline. I had gotten one when I first went stage 2 over 2 years ago. Since then, as some may know, I have fixed many small things and a few tweaks here and there and wanted to see what difference I have made. I am pleasantly surprised at the results.

I lost my original graph, but here are the numbers from my best stage 2 dyno 2.3 years ago. I think the ambient temperature then was ~75 deg, AND I was running 100 Oct with full timing. Best Run 201.7 HP, 256.3 TQ. Using 25% drivetrain loss, I believe that roughly translates to: ~265 CHP, 340 CTQ (please correct me if this is wrong). Still, not that bad when you think of it that way.







As you can see, I lost HP for each run because of heat soak. Low numbers, IMO, I was disappointed.

Today, I made sure it was cold out, and I only used 91oct tuning this time. There have been no performance upgrades since the first dyno sesh, only maintenance, and working bugs out, along with a wastegate adjustment to hold better boost. Yes, these three graphs are in the right order, I actually got better numbers on each subsequent run. Best run was 221.3 HP, 302.1 TQ. Using 25% drivetrain loss, roughly 295 CHP, 400 CTQ! Amazing! On 91 oct.








The only difference I can really see better on the first run, was it held peak Torque a little longer. Let me know what you all think!?

Feel free to add this to other dyno threads. I am also adding this to my personal thread.

Sweeeet, ^ for me it look very nice, but I do not have that much experience with Dyno runs, but my 3.0 V6 CDI engine delivers 398trq so that trq must be very nice

And this Dynocologist made me almost spill my drink

[Mc Suly]

Nice!
You have race car.

I will go for dyno in December probably!
All my mods go on :D

[Operator]

Good stuff!!!! Glad all the fixes have worked out for you. Just checked the forcast, and next weds "should" be around the same. See you then. And plan out a route for the drive.

I swear I just read this ;-)

Nice numbers, I plan on getting the car dynoed after I get my fueling issue fixed, I have the check valve and the rebuild kit and will be doing that soon. Then going stage 2+, pretty excited for the results. I have a high mileage car as well, have you ever done any carbon cleaning jim, I was considering it because I doubt mine ever has been done and I imagine it may help with power a bit. Again nice numbers

I have never done a carbon cleaning, so I am very happy with my results.

I was just wondering but from all the fixes you did over time looks like you squeezed quite a bit more power out of the car from when you initially had it dynoed impressive to know little fixes here and there can make such a big difference.

Hey just out of curiosity do you know what SPS numbers you are running? stock hpfp?

[DRAKLORE]

Damn good numbers :-) I would Gladly take them at stg2 lol

[jimrobbington]

Hey just out of curiosity do you know what SPS numbers you are running? stock hpfp?

Yes:

Boost 7, timing 3, fuel 9, stock hpfp. We might try turning the timing up to 4 when the temps stay low.

Okay thanks, I have a question if you dont mind and I dont mean to go off topic so we can continue via PM if you prefer. But I was at a 2nd revo dealer yesterday tweaking some settings with the tech there using their SPS+ (because the original shop that flashed me had my settings really jacked up, like boost 7 fuel 6 timing 6 which was giving me terrible fuel cuts with out supporting mods i guess?) Anyway we ended up after about an hour or so, 4 test drives and looking at the vcds logs, deciding on Boost 6 Timing 4 and Fuel 9. I am in MD and temps were in the high 60's. My question is why am I able to sucessfully run these numbers with no problems, when your numbers are very close to mine and you are considered stage 2 and I am considered stage 1? once you bump up your timing, we will be the same other than your boost is 7 mine is 6. So with basically the same settings, your hardware is the only thing that makes you stage 2 not the software? Sorry if it is a dumb question but just had me curious.

I appreciate your help and PM me if you dont want the thread to vear off course. Thanks

Anything performance related is ok for this thread!

What octane gas do you fuel with? Here, the best I get is 91 oct, which is why I am set at timing 3. If I had 93 oct, I would have no qualms about running timing 4. I hope to one day run meth so I can bump timing up to possibly 9.

Also, REVO has a TRUE stage 2 tune. It isn't just a cel delete like APR. They literally do change parameters when you upgrade to a stage 2 tune that only work when your exhaust is opened up. This is specifically why with REVO, it is suggested that you get a full exhaust, and not just a TP with stock exhaust, because it is fairly aggressive. You can tell how aggressive with a near 100% increase in torque over stock in my dyno!

Get yourself some exhaust mods, and upgrade to stage 2. You will not be disappointed. It's only like 75-100$ upgrade for the tune.

Ahhh I see. So although our settings are similar, there is a stage 2 program that actually changes more "behind the scenes" settings, if you will. Gotcha. I am running Shell V-Power 93 only, which is why they suggested the fuel at 9 and timing at 4, which seems to be working really well so far! No more fuel cuts at the moment! So once I get the full exhaust, I can upgrade to the actual stage 2 programming and possibly not have to change the SPS settings a whole lot. Hopefully I am understanding this right and again I appreciate the knowledge!

Also very impressive numbers also I must say!

[jimrobbington]

Yep, I knew you had 93. Lucky. Keep your timing on 4 and don't worry about it. You'll be fine. If I were you, I would get used to it like that for a week or two. Then turn the boost up to 7 and see how it feels. It was almost like a night and day difference for me. Every car is a little bit different, and every place has different weather. It is safe to mess with the settings one at a time, it won't allow you to hurt your car if you move in small increments. You will feel if it is better for performance, or worse immediately, as long as you give each setting change a week or two for you to get used to it. Only change one thing at a time, too, so you know what is changing.

Very impressive!

Awesome i appreciate the insight, i will do that and let you know how it goes! Thanks again man

[Leo14]

Awesome! Pretty good #'s imo. Revo + cold weather = fun. So much fun.

Numbers are good but every time I see a dyno from a 2.0T I shake my head.

Why is that, Sprode? I know the torque spike is crazy, then immediately dwindles down to nothing, but it still makes me smile.

For a comparison, a RS4 with stage 1 REVO, full exhaust, same exact dyno, put up 281.1 whp, and 256.5 wtq.

Jonathan

[Avantageous]

To OP,

Do you have any current dyno sheets with stage 1?

I tried searching, but kept coming up with just the sheets from 2006 with the comparison of
GIAC and APR.

Thanks.

No, sorry. Never did a dyno before stage 2, but I would assume a stage 1 should get close to my original numbers from my old crappy dyno

That is exactly why. The engine is just begging for a bigger turbo. It looks like a diesel.

You seem like you'll end up with a bigger turbo someday. You'll see.
