Jibberjive's GT2860R-7 Build Log

[jibberjive]

When it is completely complete and running at its potential, it'd be interesting to take a road trip to Cali or somewhere else sea-level and throw it on a dynojet or something to see what it puts out ha. Would be good for comparison for sure.

[AudiA4_20T]

Great job Jibb! Very well documented, there aren't many on here like that. I applaud you for doing the assembly yourself too. It really is a great feeling doing it yourself. I look forward to seeing the results

[jibberjive]

Thanks Clint. Yeah, this has definitely satisfied my 'project fever' for the next little while ha. Hope to see your swap project running soon (if it isn't already, I haven't checked the thread in a bit.)

[Ruffiano]

I ran into more nagging stuff (EGT bung has wrong threads (need to either retap or take off the manifolds and have someone weld a new bung on there), fittings stores were out of stock for the fittings I needed,

Hank has fittings, he just welded one up for me :)

Thanks man. I have avoided quoting specific numbers because the goal for this build isn't peak power, but rather a powerband tailored to my specific use (daily driving and road course). Also, add to that the factors that I'm up at 4300ft with 91 oct gas (and 2 E85 pumps in the whole valley), I'm not going to use meth, and the dyno will be a decently tough dyno (AWE stage 3 S4's put down like 299whp and B7 RS4's even less IIRC), it's tough to estimate an accurate number that would be realistic. Hopefully above 500whp, but we'll see.

Yeah, the dyno here is "tough" but numbers are comparable when you think about what is on the dyno. The fresh carbon cleaned rs4 with open exhaust put down 291whp at the last dyno, a stock un carbon cleaned one put down 265ish (not 100% on that) and John's with the fresh cleaning and open exhaust, and deflapped and modified intake and other stuff, was right around 310. I was happy to put down 293 with oil blowing directly into my intake!

Here is the thing though, Dynos are not definitive because there is so many factors to consider, just cause I can go throw my car on some random dyno pack and it says i have 500 hp doesn't mean squat if you don't have a good baseline to back it up. Using other cars on the dyno help, but what you really need to do is show gains. same dyno, same temperatures, same car, is the best way to show results. another good option is run a stock version of your car the same day same dyno, or even putting it agains Scott's s4 on the same day would be a good comparison.

For sure. If you see my posts around here, I'm the first to say that a dyno is just a tool and the actual numbers don't mean anything when trying to compare different dynos. That's partly why I haven't been going out saying "Yo I'm going to have a 550whp S4," because what does that really mean? (except to my non-car enthuasiast friends, because they don't know any other means than to compare it to magazine hp #'s). And that's why I can see the future now of when I wrap up my car. I'll make a post with the dyno #'s, and a drove of internet people are going to go, "Dude, that sucks." "I expected more." "You should let Tony and EPL tune it for you, they're getting 475whp out of Tial 605's." "AMD got 600WHP out of a 770 car." and other ignorant things like that, trying to compare dyno numbers. I'm calling this right now, consider it prophecy;) I'm the last person to get hung up on dyno numbers though.

That's why I said it would be interesting/fun to take it to sea level on a different dyno/different conditions when it's done, just to see the discrepancy.

I agree wholeheartedly with the baseline/gains stuff you said, and that's why I got a baseline of my car before I disassembled it. Unfortunately, the company that I did my baseline dyno on (Cobb) moved before my never-ending project got finished. Though, fortunately, it seems that this new dyno reads about the same, so the baseline may have some relative validity.

Who are you btw, and what do you drive? Just trying to put names with faces/cars, if we've met. PM me if you don't want it public. And what does Scott drive (not sure who that is either, I showed up late to the dyno days and haven't been to many meets)?

[jibberjive]

Hank has fittings, he just welded one up for me :)

My car/engine is up in Murray, with the manifolds already mounted to the engine with gaskets. I'm sure Hank probably couldn't just pick up and go when I call him on a random Sat, and I'm hoping that I don't have to unbolt the manis, because some of the nuts were a major pain with the way the runners interfere (and I don't want to have to buy new gaskets).

[Ruffiano]

Yeah sorry, its dave, hybrid_hatch on most forums. My ride:

[jibberjive]

Oh whatup Dave, didn't know that was you. Nice pic, taken off of Squaw Peak road I presume? And do you randomly know if there have been any stock B6 or B7 S4's that dynoed there, and approx what they put down?


I pretty much just made a decision aesthetically that is going to be awesome if it comes to be. This is one I'll have to hold out with until is done and ready to show.

[TweetsS4Estate]

Dude, SUPER exciting. I can't wait to see how your setup performs!

[Ruffiano]

We'll have a local dyno day in a few weeks... DO WORK!

[MikeyB3]

Sick dude! Cant wait to see this in action!

[jibberjive]

We'll have a local dyno day in a few weeks... DO WORK!

I would LOVE to make it...but even if the car is running by then, it'll just be on a break-in tune running wastegate spring boost and the stock fuel pump. So it wouldn't even be worth my money to throw it on the dyno. I might try to stop by though.

[davenew]

So.. What's left to do before dyno tuning?

[jibberjive]

Lol, well, here's a crude list from an earlier post, and I haven't really touched the car much since (and most of my tuning will be done on the street, not the dyno). I've got a couple of days at the shop ahead of me.

I'll pull a BigBoost, with a checklist (as much for myself as for the build log). Not necessarily in order.

Checklist:
1. Finish up turbo lines (Get replacement 034 oil pan adapter, get oil inlet lines modified, assemble rest of lines, get fire sleeving) DONE (except for assembly)
2. Get flywheel bolts ground downDONE
3. Powerwash engine bay and undercarriage
4. Polish bipipes
5. Assemble rest of engine (serpentine assembly, intake mani, flywheel, tranny, etc)
6. Do 'big 3' wiring upgrade with 0 ga, and wire car for trunk battery relocation, install wideband and sensors (Zeitronix, WB02, EGT, Boost)
7. Reinstall engine
8. Install ER's
8.5. Install HID kit and Depo headlights
9. Startup!
9.5. Install interior
10. Get exhaust installed ('cats' , v-bands, and extra resonator welded in)
11. Break it in and tweak the tune!
12. Finish developing custom intake manifold, custom catch can, and custom dual 044 surge tank and nitrous setup
13. Assemble fuel lines and install new fueling setup (surge tank, pumps, lines, rails, FPR, ethanol content analyzer)
14. Self tune for E85!

I'm sure I'll be adding to this list as I remember more stuff.

[URHank]

when do we tune Mike? I need a good fast b5 s4 experience to push me over the edge and purchase one.

You, possibly crossing over to the dark side (of Audi)?? I spent a ton of time at the shop this last week, but still have like one more day to get it running (I'll post an update when I get time), but I just got your voicemail and I'll call you. Also, if you need a fast B5 S4, it won't be mine for the first little bit, because I'm going to be running wastegate spring boost (13lbs IIRC) and with the stock fuel pump for the first little while, while I break the motor in and build the surge tank/catch can. So it won't necessarily be fast for a while (probably seem like a Toyota Corolla compared to what you've been driving ha). The stroker getting a little unrealistic for daily duty?

And a teaser pic for everyone

[shorterthanrich]

Dude. Shit yeah.

[2380S4]

That looks great!! Hope mine looks half that nice.

[URHank]

Wow, that looks great Mike! Do you have the downpipes built already? I can't wait!!

I really don't need another car, but there is a potential deal to be had... I am going to go check it out this weekend I think. The URQ has been sidelined with transmission woes(the 6 speed 01e lasted 4 hours with the new stroker) then with ECU woes. The new transmission is in with updated parts, high bias center and torsen front. I sent in the ECU for ignition driver repairs and then hopefully I can get her on the dyno. I picked up a new turbo in the form of a HTA3794r, so I am excited to see how that guy makes power on the new 2.6L. I am hoping for high 700s and maybe can pull 800whp at 40psi. Should be the 1000hp at the crank!! The 10:1 2.6L is fun and I am sure it feels a lot like the 2.7tt that rounds up to 2.7L worth of displacement. I can cruise up Provo canyon in 6th with little effort! I am seeing full boost by 3700 with the hta3582r!!!

[jibberjive]

Dude! I may have to have you volunteer me a ride when it's done :) (I don't dare ask for one after last time, I hope that turned out ok for you). I didn't know you were going that high of compression, I bet that thing rips! If/when you put on the smaller turbo for road course duty, it'll literally be insta-spool.

Yeah, I've already got the DP's and actually the exhaust as well (4"), but the exhaust was custom made for a different DP setup. I'm looking to weld in some fake cats and v-band flanges on the exhaust, and that's where you come in It prob won't be til the 15th or so until I'm able to get back up there, but I'll let you know when it's done.

Dude. Shit yeah.

That looks great!! Hope mine looks half that nice.

Thanks Rich and Ken!

[highPSI-S4]

Win

[shorterthanrich]

Yo man, where's this at?!

[AudiSportB5S4]

He didn't post it here because he doesn't love us.

[shorterthanrich]

NIICE!

Jibb! HOW COULD YOU!?

[Korben007]

Where the rest of the video?

[UkuRiSh]

congratulation man she is alive sound good .

[jibberjive]

Clutch and motor broken in, approx 1200 mi on the engine. I'm off headed up the canyon right now to hopefully tune/optimize my current setup! I'm not sure how much I'll be able to turn up the boost on the stock fuel pump before I start to lean out, but I assume at least a little bit more than the 15psi I have been running. I've got a wideband and all monitoring set up though, so I should be able to get it pretty decent.

[IgofastS4]

Jibb Stopped by my house today, I was able to see his car, when he pulled away and got on it man oh man it sounds Amazing very nice car !

[jibberjive]

Thanks again Chris! I just got back like an hour ago ha. BTW, you should get you car done for this summer and blow some minds;)

Anywho, minor thread update, I can't show much right now, but be stoked people! I just made some awesome headway into my fueling setup, and figured out something incredibly ingenious that the big turbo peeps or people looking to go balls out E85 on a budget are going to be loving me for!

o rly??

[jibberjive]

And for reference for people, I just got 27.07 mpg driving 215 miles on the highway the past day and a half. Crazy because I had the windows and/or sunroof down for a bunch and was cruising around 80. I've got some MPG tricks up my sleeve as well, and when I get my tune honed in, panzer plate on, and 2.0t coils in, I'm going to go easy for a tank and see what I get. Kind of interesting I got such good mileage, considering I got my worst tank ever, 12.x MPG, the previous tank (though that was with continual fats testing and lots of parking lot idling to keep warm while I view logs and tune).

[jibberjive]

o rly??

Rly. This is one cat that will not be let out of the bag prematurely though. This is a relatively short honest timeframe for completion though, unlike everything else I do with my the S4's.

[jibberjive]

I guess I've got other non-fun updates as well: turned my front rotors, replaced my rear pads, got a replacement set of bipipes in but yet to install (I had one of the very first sets from 3 or 4 years ago, and they are oddly shaped). Picked up some Y-pipes to finish development on the catch can. Yeah.

Matt, what's your status? Motor assembled?

[Matt Danger]

About 50%. Fitting the rings this weekend.

Looking forward to hear more!! Getting close to buying fueling parts!!

[jibberjive]

Random quick update. Met up with a buddy (Nvrsummer or something on here) with a VAST stage 3 S4 (~19psi, stock IC's, walbro 255 lemmi-tweaked) to go on a drive this last weekend. My car is currently still on stock fuel pump and ~15 psi boost, I've got a small vacuum leak at the DV, and my 3rd gear synchro is grind-y (these are the facts of the car, not excuses). Over the course of the drive we were able to do a couple of pulls. We did like a rolling 2nd gear and a rolling 1st gear pull for the legit pulls. He probably jumped ahead a hood-length for the first second or two, then it was pretty much dead even til the top of third, then I kept pull-ing a couple of cars by around the top of 4th (maybe even 5th?) before we shut it down. It performed almost exactly where I though it would, just about even with an average stage 3, then maybe pulling a little in the higher gears/higher RPM's. They were really casual runs and completely for fun; I'm sure neither of us had the ideal pull or our cars set up ideally. It was just the two of us, so no videos. Good times though. I can't wait to throw in proper fueling, turn up the boost and refine the tune more!

..just about even with an average stage 3

I would call that a less than average K04 setup considering he can extract a good amount of horsepower still with that setup. Regardless though that must have been fun! What is holding you back from the fueling? $$?

I would call that an average stage 3 considering it's a full vast stage 3 with lemmi tweaks. The only thing it's missing is ic's, which wouldn't have made any difference really considering it was around 40 degrees ambient. I don't consider meth injected custom tuned cars 'average,' considering they run similar boost/timing to race gas cars. I'll likely be tuning this car in the near future though, so we'll see what we can get out of it. Either way though, not trying to brag or prove any point (I know for a fact that neither of our cars are where we would like them), just reporting some fun casual runs with a buddy. Take it as you will, and possibly with a gain of salt.

I thought the stock I/C's had serious flow issues as well?
