Skywagon's Return to the Dragstrip

exactly, he’s trapping like a full bolt on RS4 with 93 octane fuel…or a stage 2 3.0T on pump gas. Nothing like a maxed out TVS1320 3.0T on race fuel

He’s about 5 mph and 3-4 tenths down on the fastest guys (11.5 @ 118-119 vs. his 11.98 @ 113). That means he’s down about 50 hp.

So is it the headers hurting him? No, we’ve seen that GIAC cars and APR cars with/without headers run the same times. The headers are useless for any gains but don’t cost you 50 hp.
You can’t blame the meth anymore because he turned it off.
Can’t blame the hood hole because it’s supernumerary.
Can’t blame tire spin because it’s (AT MOST) costing him a tenth of ET, but tirespin doesn’t cost you any MPH, so that’s out.
Can’t blame his other bolt ons because he has the right stuff.

That leaves the tune.

All in all, clearly REVO is not getting it done. Their methodology used to produce impressive results when the platform tunes first came out (impressive relative to APR and GIACs first attempts), but 4 years have passed, and REVO is no stronger today than their 93 tuned cars were in 2011. I watched a REVO 93 car with LW wheels, tune and intake trap 113 back in 2011. Here’s skywagon 4 years later with another $5,000 in mods thrown at his car, and he’s no faster or powerful

he gained 1 tenth of a second. Could be entirely attributed to DA improvement vs. last time.

#23

Haha, exactly! Sky, seems like you reached your goal, good for you.

  1. I did not start this thread, cloucher did.
  2. I do have videos of three runs, tires spinning in all three, all day as well.
  3. I saw 116-118 mph on the speedometer through the traps. However, print out trumps all.
  4. Weather in the 30’s night before. My best run occurred about 2:00 PM when sun highest.
  5. Unsure but wheel spin/hop may have sent signals to DSG causing short shifting during most of runs shifting from 1st to 2nd at about 5500 rpm despite using manual to hold in first gear.
  6. My Michelin Pilot Super Sports have about 12000 miles on them. Finer tread all gone. New tires needed.
  7. The car is spending about 1/2 a second looking for traction.
  8. Yes, the REVO tune is making enough power to spin all four wheels at the line, especially later in the day, lower sun.
  9. I couldn’t care less about speed, ET is all that matters.
  10. I was there, none of you were.

Ed, Sorry if I missed it, these passes were on race gas/tune correct? Can you please post the vids and slips? Did you data log any of the runs?

Glad you made it into the 11’s! However, and I’m not going to go back and forth with you as that’s a waste of time the trap speed is very low as has already been pointed out by several folks. My guess w/o your logs and based on the logs I’ve seen from a fellow who got the tune after Revo made whatever changes they made to the file and he still bypassed over 12%+ boost on average run… timing values are much more in line with giac/apr tunes but haven’t seen any pull yet, zero, nada, none! Summer logs will be real interesting… Anyway, did your car spin? Maybe and you did the right thing lowering your tire pressure to try and combat it, but any amount of spin that you are getting won’t take your trap down 4-6mph which is what you’re missing and more likely bypass related but I’m no tuner so who knows ::slight_smile: You should make a post over on vendorzine where Revo’s pedaling these tunes and ask them why your car is trapping so much lower than others, it can’t hurt. Then do some logs and post those results…

#26

Audi speedometers tend to be wrong. Mine have always read about 3-4 mph high at high speeds. You have different sized wheels which could exacerbate that difference.

Further the trap speed is your average speed over the last 66 feet so if you cross the finish line at 114.8, your trap could easily be 113.5.

#27

also

TRAP SPEEDS ARE NOT INFLUENCED BY WHEEL SPIN SO QUIT FUCKING TALKING ABOUT IT!

you posted 8 or 9 points 5 of which were information about the runs and 4 of them were about wheelspin

Dumb as a rock

The reason your et is SHIT (make no mistake it sucks for a fully modded car on race gas in great DA) is because your car is down on power, not because you’re spinning your tires on the launch.

Post your videos already so we can see you spinning for half the track. You’re so out of the loop you don’t realize how impossible that is. You will spin for twenty feet on a bad launch. You will chirp 2nd gear. That’s it. You’re not spinning for 100 much less 600 feet.

#28

OMG did he just say revo makes enough power because it spins all 4 wheels? Stock s4s spin all four wheels.

Anyway based on your member rating you will have to be content to just frustrate the people on audizoo.

#29

Ron, no logs, concentrated on driving. I’ve never had tire spin this badly before. The day before I went out and did some practice runs on a highway. Zero spin and it as 45F, LC worked and no short shifting. Will get some logs and post slips and videos soon. One run I had a 1.67 60ft despite bad hop on all four wheels. Thanks

#30

1.67 60 footsie top 5 all time cars. So no, your wheel spin is not hurting your et or your mph.

You ha e other issues.

Say that out loud.

#31

Skywagon, ask yourself this one question. What would we gain by lying to you OR calling you a liar?

People on this forum were trying to help you from the start, even though the help wasn’t received well at all!

We have absolutely no reason to sabotage your attempts at the strip and the members on AR have a great appreciation for guys like you who test their cars at the strip. The problem is you don’t want to hear any of the constructive criticism and prefer to act like an idiot or babbling fool.

Your attitude and Homer Simpson designed skull are truly fucking amazing.

2 thus is great. The last trip to the track I suggested this. Good video will help make more sense of the passes. I with several others spin hard each time I make a good pass so you saying the car spun and that’s a big reason why you feel the mph or ET is low wouldn’t make sense. But with video it puts all that into perspective with your car.

  1. It does suck. The faster you go the further off your spedo is. Especially if you have different rims and tires. The little difference throws off the speed. Heck even the stock stuff makes the spedo off.

5 this would really impact things. Of you got lots of hop that could happen. And that would make a big difference

  1. That too if the tires are shot your not going to get great traction

  2. This is again what’s great about the video post it up. That should really help everyone see what you experienced

9 Primetime made a very very important post. If your car is bleeding off boost your car is going to die up top speed wise. Logs would help tell the rest of the story.

  1. If you have the video and logs the great thing is you can have all of us with you.

I would say your trap is low. Spinning usually gives you a better mph. It does so because the wheels are spinning at a faster rate then what they normally would be able to achieve under traction. At some point the car catches up to the spinning and the result is a impressive mph. That’s normally what happens. I would guess others will say the same. On some of my worst spins as the line I get more impressive mph. Logs of the runs would help tell the story. Add in the video and it becomes more clear when people actually see what you went through

#33

The videos were taken from down the track but tire squeal can still be heard, all three videos. I have a Go Pro but as I wrote I concentrated on driving yesterday. Will get logs ASAP…tomorrow? I know the traction was relatively good at the strip for the big slick cars. I actually saw a couple of wheelies.Of course they smoke them and heat them up. I did a couple of launches after clearing the water, got the wheel hop and spin, hoped to clean them off some but didn’t help. I was able to clear most of the water, most of the time. When I practiced my runs Friday I was using 93 Octane and the 93 octane file. I doubt the 104 octane and Revo race file could make that much difference?? Thanks much.

#34

P.S.
The gent that handed out the time slips owns two Audi’s. Has an interest in my success. He told me I was hopping so badly on a couple of runs the car was moving sideways to a degree.

#35

Post your slips and videos…stop try to attribute your crap traps to tire spin. What was your worst 60’? 1.79? If so, your a delusional nut to think your loosing 4 tenths and 5 mph because of tire spin.

Yeah he owns like a 98 A4…you’d rather trust him than people here who own and have owned multiple S/RS models

#36

I feel the need to play rodeo clown for a minute so Skypilot can regroup and amend his bucket list before advanced age degeneration sets in.

Here’s a video of me fucking up a P85D launch in insane mode. I think it took over 4 seconds.

sky,
not that this will help at all since you dont seem to want to listen to all the smarter people in here for some odd reason. But maybe since I am also running Revo you might pay attention to this. the 113 trap speed is a serious issue. On Revo 1+ that was my speed to get 12.36 but my 60’ was 1.80. so EVEN with wheel spin you are still winning off the line. At some point your car is just loosing acceleration.
It funny its similar to the JGC SRT8 twin turbos. they come off the line with so much but at a certain speed the fact that it is like a refrigerator box slows it down.
you should really start logging. with the information that was posted it is very easy… maybe someone can send you a setup file… i know i have a few saved that is set up to log certain perimeters. so i just open that file and click Turbo, and group, and am on my way. Is it possible to send those around to help him?

#38

Did Skywagon ever weigh his car?

All this talk about how slow the car is and I personally haven’t seen the weight posted either here or on AZ.

It may not explain the “missing 50hp” but could account for a good portion of it.

Scales are around, you just need to look for them. A number of tracks either have a drive-on for competition races or they keep portable scales hidden in the tech area. All you have to do is ask. Or visit a truckstop as they often have a scale, at least in those states that monitor truck weight on interstates.

#39

Skywagon has said again and again that he doesn’t care about trap speed. He just doesn’t care. Everyone says that’s how you capture objectively how healthy your tune is. He doesn’t care lol.

Although his goal of “11’s” has been achieved, so not sure where he goes from here. Now it’s just picking up “.5 sec et” with new tires :-\

Boosteasy: he posted his slips from runs before and his car is doing great on the 1/8 mile, so he’s losing speed up top, which apparently signals tune or hood hole problems. This time to the strip at least eliminated the water/meth issue, but he had his car tuned on a dyno by revo. They claimed to have fixed the boost bleed off issue.

Also, skywagon has logged before, let’s give him some time and hopefully he’ll do it again.

#40

I’ve spent a few hours teaching/helping Ed log… To be fair he has the wireless version so it is different but logging at the strip would have been my #1 priority as we would have our answer, confirmed…

I doubt it’s the weight unless I missed him adding something to the car?

Again, I’m 99% sure it’s boost bleed in the upper gears as demonstrated by another car that got this tune after sky… Oh and he returned it and is going GIAC FWIW… Losing that much mph is coming from the tune so in this case it’s timing or boost and I doubt it’s timing since all the logs I’ve seen show good values and we’ll know Revo doesn’t pull timing at all… lol

  • karma to Euro… Can’t wait to hear the reasons, err I mean excuses from Revo…
