    No. 405 to 413.

    RS3 8Y:



    RS3 8V:



    The 8Y definitely has more area under the curve in both torque and hp. Look how flat the torque curve is. From 4400+ RPM, it maintains 20-25ft-lb more all the way across and power is higher as well.

    I'm selling the 8Y version of that exhaust if anyone needs it

    Check the marketplace!

    Definitely a good comparison. But that 8V graph is quite choppy at the higher RPM. Timing issues or whatever? Typical when more boost is introduced.

    They say the "data is directly from the dyno" but the graph looks like it has smoothing turned on for the 8Y. The 8V graph looks much more like an real raw dyno output, but there are many levels of smoothing so one might have a low level and the other high.

    Other companies transpose the entire dyno run into excel and put a representative curve in place of the real data, smooth or not.

    Smoothing the graph is one thing.. the 8V drops power pretty significantly and like a rock which to me indicates something going on with S/F/T. You would feel this drop big-time when driving. I'm no engine builder but that's what it looks to me.

    I could be wrong, but I think the haldex in the 8V always caused some choppy dyno graph results when running AWD. Maybe the new rear torque diff/AWD on the 8Y provides for smoother graphs.

    With that being said, dynos can be all over the place depending on what type of dyno it is and how they've applied correction. I got my 8Y dyno'd on a Mustang dyno, aka the "Heart Breaker". My 8Y dyno'd 376whp on it with an E25-30 mix in the tank on JB4 map 0 (stock boost). I dyno'd 421whp on Map 3 on ethanol mix, Forge hardpipe and K&N drop in, but as you may remember, I was heat soaking bad because the dyno people dyno'd the car with the hood closed and a small fan blowing on the front of the car. The car was pulling boost/timing like crazy above 5000RPM, especially for the last two runs on Map 6, but my numbers were pretty much identical on Map 0 and Map 3 to what Burger shows on their site. They got 424whp on Map 3 on 93 octane. Burger does show Map 4 on E30 was 476whp, but I find that hard to believe. I don't know if that was a typo or not, but Map 4 is only 1psi greater than Map 3 and I just don't see a 50whp gain from 1psi. I'd say Map 4 is good for 430-435whp tops on 93 octane. Map 5 on E30, maybe 450, and then since Map 6 is "custom", it really depends on the boost curve you throw in your user settings, but I would say 475-480whp is easily attainable; a bit more if you're on an aftermarket IC and 4" intake. Map 5 on E30 for me was enough to slowly walk away from a 991 GT3 (manual tranny) from a roll. 500hp and I'm having a hard time finding 6-speed acceleration performance on the 991 GT3, but it looks like 0-60 mid 3 seconds and 1/4 mile in the low to mid 11's in the mid 120 mph range. PDK's are faster.
    Any hardware aside from e30 on map 5? Keep in mind, the intake/turbo inlet/plugs and intercooler, do make a very noticeable difference. Im honestly thinking of just keeping the JB4 long term, as I am content with the power delivery on map 5/6.

    I would really be motivated to make the switch to Uni, once they have a TCU file on hand.

    K&N drop in and a Forge 3.5" hardpipe between the stock airbox and stock turbo inlet. I have a Wagner IC sitting in my garage that I will probably install this Spring. I have not replaced plugs. What are you using? I imagine they're easy to replace?

    NGK R74379 and definitely recommend you swap them out every 10kish miles, if you are also regularly using ethanol. Super easy install.

    Just ordered a set from FCP. Best price I could find with free 2-day shipping. Thanks!

    Personally I'll be giving the Brisk Racing plugs a try shortly. Race proven and MUCH cheaper

    I'm also on JB4 with JDY intake, CTS elbow and full titanium exhaust at the moment for what it's worth

    +1 for Brisk Plugs!! Had them in my 8V and swapped them every 10K!

    Wow. Those are substantially cheaper. Looks like it's too late for me to cancel my FCP order. Oh well. Next time.

    Will the 8Y RS3 ever be tuneable?

    They also don’t last nearly as long

    I’ve used both - decided to stick to the NGK for the long haul.

    Yeah. I guess the $150 difference every 10k miles is insurance to get a plug from a well-branded company. Last thing we need is an electrode let loose at 6,000 RPM and 26psi of boost.

    I have had Brisk in other previous Audi applications and personally think, it does not do as well as the NGK's. I pay more for peace of mind any day of the week.

    The Brisk plugs are rated for 18K miles where the NGK are rated for 15K miles.

    I wouldn't run either that long but it also comes down to what heat range you're looking for and what you plan on doing.

    Again not saying NGK is bad I've run them forever in numerous different vehicles but going to give the Brisk a try.

    Well to be fair, their upside is they are silver so it doesn’t break off, it melts

    That being said, I found myself having to regap then a couple times per interval. Haven’t had to touch the NGK

    NGK is also the preferred plug by Unitronic. I have not had to gap my plugs neither, for now.

    Does running E85 require plug changes more often?

    It can, but my experience has been that it hasn't really mattered. This engine is different than my last one so will have to see, but I never had any issues running the same plugs for 20k or more, that engine was making 600 HP on e40 with methanol. Just log it periodically and if timing is good you are fine.

    I hated the brisk plugs I ran before (different engine, but really turned me off). Normal daily driving they wouldn't get hot enough and fouled in like 2 weeks, misfires like crazy. Went back to stock NGKs and never had another issue, nothing else changed, just the plugs.

    I'm sure they are great for the track or maybe in the summer but I've no interest in running them on the street, especially in the winter as they were garbage for me.

    The general consensus is yes. A simple install done every 10k miles and Im at ease with any possible unhappy logs that may be related to this.

    Isn't the longterm problem with running e85 is that your car and rubber components and such aren't designed to run that type of fool so it can eat through components in the fuel system not made to run E85?

    Look at FCP's lifetime replacement warranty, makes new plugs way cheaper after the initial purchase.

    Maybe. What I've read was the more E85 you run as a percent to gasoline the less detergent there will be to keep things cleaner etc.. plus the corn juice is stickier and gums up things.

    I think there was an issue with older cars and ethanol. Not sure if the newer ones have an issue with lower percentages 10-30%. I run a few tanks of regular gas through my car every 4-5 tanks with an ethanol mix with a shot of Star Brite fuel treatment.

    That's good to know. Now if only there was a station near me that sold E85...

    Depends on the material but in general yes the alcohol will be harder on all of the fuel system components. Running a blend will be less harsh than straight e85. I use StarTron fuel stabilizer and cleaner frequently. I ran e40 in my SQ5 for about 3 or 4 years and it never had any issues. Maybe long term in that 7 to 10 range you would start to see it, but more likely will just cause some parts to be replaced a little earlier.

    Uni has the price listed on the website at $1,300. I don’t remember seeing that before. My guess is that it’s close. Otherwise I don’t think they would’ve put it up.

    Their post before the new year made it literally sound like it was coming 24-48 hours into the new year, but it was just another #2weeks lie.

    I like Denso 5749 much better than NGK and they're cheaper. On full E85 it's best practice to swap out plugs every 5k-7k miles. If running Brisk, you definitely have to swap them out at the 5k mark on full e85.

    We've been waiting on something that was out of our control and in our opinion mandatory for us launching the software. As of last week its completed and now we are working on ironing out the launch of the product with marketing. This will happen sooner than later.

    I hope everyone appreciates all the hard work our team has put into this , as its a very small market but one we love
