Got any updates bro...

Car is at the body shop currently having the front bumper sprayed, then back to 034 for new midpipe on exhaust and install of a full RS4 intake manifold. We've just been waiting on the RS4 charge pipes to get here from Germany, but the holidays are delaying the process. Hoping to get the car on track for more testing soon though as the first race weekend for NASA is coming up fast (Feb 12-13th) and we wanna be in great shape by then. Will definitely keep you posted though with dyno numbers upcoming soon and some pics/vids to follow! Thanks for your invested interest!!

Did you end up flaring the rear fenders? I remember you mentioning that you were doing something other than the standard RS4 rear flares.

We were in the process of planning it when the engine blew, so we had to divert those funds to the rebuild. But hoping to get back on that soon! Will keep ya posted as we move forward with other projects.

[S4DTM]

Back from the body shop with a fresh paint job!

[wdbdy2000s4]

that's one tough looking s4. Congrats!

[gollygwagen]

Looks great man! Looking forward to following the 2011 season!

[S4DTM]

Thanks guys! Can't wait to get the RS4 manifold stuff on and dyno the beast!

[S4DTM]

Hey all, so we've been working hard with 034motorsport to get Giggles ready for the upcoming season. We finally got all of the parts for the RS4 manifold in, and installed this week, and the dyno testing/tuning began today. Tuning will continue through Monday, but here's what I can tell you so far:

1.)To run TTS this year, we need to be about 420whp. So with this new software, they were able to get Giggles to run at 420whp...from 4k all the way through the RPM band. Not to mention the turbos are spooling to full boost about 3300rpm...the same as a K04 car! That's pretty amazing considering pretty much every car loses horsepower as it moves through the rpms, and that RS6's generally cause much larger turbo lag!

2.)After working with this, they found that at the top of the RPM band our injectors (550cc) were running at 100% even before hitting the limiter and the car was running too lean...so, new injectors will go on Monday (720cc) and we should see a difference. Didn't want to be running at 100% injectors below the rev limit!

3.)The highest they ran the car was at 20psi. They plan to run it a bit higher just for shits and giggles (get it ;)) to see what we can put out, but with the injector issue they wanted to wait. Our engine can handle a lot more, we're more just running off the limits of the RS6's. Anyways, at 20psi, with inhibiting injectors, they got 480whp out of the beast!

4.)I will have more info on Monday; however, we should see at least one 500+ run in there. Keep in mind, we went with smaller turbos on purpose to maintain the racecar ability, not full out power, so these numbers are awesome! Anyways, stay tuned!

^ Nice update......... Are you going to post the dyno sheet? These are custom intake wheel Rs6s right? They are not PJ RS6 turbos.

[Korben007]

awesome build! cant wait for results lets see them!

[cjk]

Congrats on the results man!

They're OEM RS6's, our K04s had custom intake wheels.

awesome build! cant wait for results lets see them!

Thanks man! Will have more info soon, but the vid below should be a good preview!

Congrats on the results man!

Thanks!


Okay, so here's a lil video preview of the results with a dyno screen shot. They're still fine tuning things, but this is at least prrof of the process! Enjoy!

[S4DTM]

Sorry for the delay! Here's the Dynos:

TTS Class Map (What we will be running):

You can see how consistent the HP and TQ are throughout the power band! Gonna have very little power loss as we move through the rev range. Boost is electronically controlled to lkeep the power constant through the band. 420WHP, 514WTQ @ Boost Range of about 23-17psi

High Boost Map:

Here we ran the boost up higher; however, our fuel pump couldn't keep up with need for fuel. You can see that the A/F ratio is all over the place, and even with the injectors being turned up, there just wasn't enough fuel for us to get solid power all the way across. When we decide to run the engine at higher boost as some point, we will need to change out the fuel system (pump, lines, etc.) for some larger stuff. 463WHP, 514WTQ @ Boost Range of 23-20psi

Warm-Up Map:
This is the map we will use for warm-up before races. Running at about 14psi on acceleration and just getting the engine ready to go! 415WHP, 389WTQ @ boost range of 14-17psi

Anyways, you can see the strides that 034Motorsport took to prepare some amazing tunes for us! We're really excited to get her out on the track Friday and see what she can do! Huge props to Christian, Nate, Javad, and all the other guys at 034 who have helped to bring Giggles back to life, bigger, better, and stronger...you guys kick ass!

What is the smoke coming from the drivers side of the engine bay? 6-11secs

[Don Supreme]

nice dynos, but i guess it didn't really make 480 @ 20 psi after all huh.

TQ looks pretty damn awesome.

Well, we were tuning the car to be set at a certain HP, rather than see what we could get out of it. The boost is electronically controlled and so it drops over time, which changes the power curve. When we did push it up, like I said the fuel pump just wouldn't keep up. It can make more power is we adjust the tunes and up the fuel pump abilities, but we were focused on getting it track prepped.

[S4DTM]

Update: Here's some pics and video from last weekends race. Very successful first weekend with the new engine, as we ran 1:49 and 1:50 back to back, putting us second in class behind a lighter Z06 on 315 tires...our little 245s are gonna need to get bigger, haha. Anyways, enjoy!

Holdin off a Viper ACR!


Slight fog made the track temps perfect for that 1:49


Cool Down

Sorry for the delay in posting, took me awhile to get the vid together. Good weekend for us overall, although it was a lot of work! We started off the weekend fighting with our shifter all Friday night trying to find all of the gears. We finally called it in for the night with only having 3rd-5th gear, and no reverse. We figured this was better than the other option of 1-4, as T-hill is a fast track where 3-5 is used. Without enough time in the morning to attempt another try, I headed out for the first session and found out quickly that we now (without changing a thing from the night before) had only 1st-4th gear! So, after running a very slow session, dicing with the miatas, we began an investigation into the shifter. We found that the bushing on the stabilizer arm of the shift rod was completely torn, so after a large hole, a lot of cursing, some blood, and some awesome teamwork, we were able to replace the bushing with a home-made solid one, and the car shifted better than ever! Seth was up next and, having missed the second session and being way behind in position, he went out and ran a solid 2:04, putting us back up the grid to 9th from 25th! We went into the second day motivated and ready for some solid times; however, still skeptical of our malfuctioning steering angle sensor which took away our ABS/ESP. The first session was way later than normal, allowing me perfect conditions for a team record 2:01 lap. With hours between the 1st and 2nd session, the track heated up fast; however, Seth still went out and solidified our 3rd place finish with a 2:02! Overall, we were happy with the results and breaking our record, but both of us feel that we have a good amount of time left to drop. Next months goal: break 2mins!

[*Blue-Angel*]

Thanks for the video and the update :)

[Max@034]

Great to hear and see the progress!!!

[Reich]

Congratulations. That helps a lot on the S4 name. Way to go.

[S4DTM]

Thanks guys! we had an unfortunate visit with the wall at the March event at Infineon, but luckily only cosmetic stuff, so it was nice to get back out there and pull some good times. Thanks for all the continued support!

[S4DTM]

Ran a new best of 2:00 flat this weekend. We brought the rear end up a bit, which decreased the camber and actually gave us more oversteer, helping us corner a little better. Unfortunately, we had an incident with two other cars after this and ended up with bumper to bumper contact and a broken radiator, ending our day. But we'll have it back up and running in time for Vegas first week of June (Wustefest), and Infineon the second weekend of June! Here's the 2 min vid, enjoy!

[S4DTM]

Thought I'd throw up an update:

We joined one of our sponsors, FRRG, at a private track event at Chuckwalla Valley Raceway a few weeks ago, and had a great time with some great people. Here's a video of the entire trip, but obviously Giggles enjoyed the track more than sittin at a car show, haha. Car was running great, until our throwout bearing broke in half a few weekends back. In the process of being replaced and getting her back on track for August. Also threw up a few pics just for fun. Thanks!

awesome video

[*Blue-Angel*]

Did you ever get this car on the scales. Curious what it weighs and what I can expect my car to weigh. Thanks.

[AudiA4_20T]

Sick pics. the splitter looks mean

[S4DTM]

Did you ever get this car on the scales. Curious what it weighs and what I can expect my car to weigh. Thanks.

We have it down to about 3250. We've been messing around with the weight a lot trying to get it balanced. WE had a hug front bias that was throwing the car off, so we actually added about 150lbs to the middle-back of the car to help, which made the car handle on a whole new level. We have to be careful dropping weight due to classing, but at some point we hope to drop it below 3000lbs.

[*Blue-Angel*]

I know exactly what you are talking about. Yeah where yo are right now your in somewhat a sweet spot as far as classing goes. However I believe I will be around the same weight as you ~3050. At that time I will weigh the car and play with some adjustments and add weights were needed to counter this front end pig heavy car.

Thanks for your input.

[S4DTM]

Glad I could help! Good luck, let me know if you need anything else

[S4DTM]

Few updates:

The new transmission is nearing install after months of waiting on parts. We decided to go with a dog-box style tranny, with straight cut gears. We also changed the ratios a bit, although they are still pretty close to the allroad gearing we had in there previously. The new unit should be very strong and reliable, as well as give us a little quicker shifting ability without the worry of the syncros. The gears were custom cut by PAR in Australia, which was part of the waiting game. We also had Scotty at Advanced Automotion (also the tranny builder) put together a Wavetrac front diff for us.

While we've been waiting for the tranny, a few new projects were undertaken. New stronger, thicker 034 axels replaced the old ones, the rear LSD was taken apart and cleaned up, bushings were replaced with 034 billet units, and a new single piece driveshaft will replace the old two-piece when the tranny is installed (thing is a beast!).

We're also currently in the process of installing a fuel cell and new fuel lines/rails in preparation for the NASA GTS series, which we will hopefully begin this season. Anyways, here's a few pics and I'll post more as they come. Cheers!

Old 3rd gear (never good):
