Place your bets...

Oh hell…gotta see this one!

Looking forward to it. Should be interesting to see what you think.

Glad to hear that news prime. Looking forward to your impressions

Fantastic news! Looking forward to getting some numbers I can trust!

Looking forward to some honest unbiased information on the kit and its performance…thanks for taking the leap and trying to get honest information for everyone on the forum…such an asset to the platform

Great stuff Ron. Really lame they won’t let you install. Looks easier than stage II plus CPS.

The more i read about the kit the more I think its a sinking ship. For me I like to see the honest companys and there products do well. With guys like you and the others behind the kit that is only good for the platform. The one thing I have seen is if it isnt working your going to talk about it and not pull punches.

With all the reports of different pulley no catback no seats slicks. Do you have any worries about the kit.

Nope… But I also don’t have unrealistic expectations like many others. At the end of the day it’s a slightly larger compressor pushing more air, however it’s not that much bigger so people are expecting too much.

My guess is Eric has the tune nailed but you never know, it may take some dialing in? That’s why I really want to get it soon so I can get lots of opportunities at the strip this year in varying conditions. I’m sure others in cool climates have already been testing and taking logs. no? ::slight_smile: Want to see boost levels, iat’s, timing, retard, egt’s a/f, etc. This will tell the story and produce the results, as I don’t think APR ran this in cold climates yet?

I also want to tweak the intake as I will run open element and I think Richi is doing that also. More or less just jazzed to have something different with the car and enjoy playing with it and seeing what it will do?

FWIW the F80 M3/M4 hasn’t gotten into the 10’s yet. 11.8@118 stock on 93 and 11.2@126 tuned with 109 octane.

Please clean that dirty ass filter :wink:

Haha I did already.

I think that’s about to change come this fall with better temps.

[quote] I raced our 2015 M3 w/ JB4, PURE S2 Turbos, BMS intake, BMS meth, Dodson clutch packs, and Nitto 555R tires. Full weight. And was able to set a new F80 trap record. It’s actually probably a new F chassis trap record. Best of 3 runs was 11.4@135mph on unleaded race gas on a 90+degree night.

And that is with 2.2sec 60’ time.

This was a good set of questions.

[quote]So let’s set some expectations here. I know there won’t be slips, but pbox will presumably be used. We know Auditude can run 11.5x. APR ran 11.1 in horrible DA, but with significant weight reduction, slicks, and a non-production pulley. Many make the leap that in better DA, it will break 10’s (even at full weight?). So, what would constitute vindication for APR/Magnuson? Richi should pull on Auditude, but how many car lengths? I’m thinking it’ll break 10’s, like 10.9 (ha) and put about 3 (or more) car lengths? Any closer and APR should have some splainin’ to do.

Here are my guesses…conservatively.

The APR run was 11.15 @ 121.5
remove slicks = 1.5 tenths and no MPH…that means normal tires is 11.30 @ 121.5
normal wheels/tire weight = 0.5 tenths and 0.5 MPH …that means 11.35 @ 121.0
remove protopulley = 2 tenths and 2 MPH…that means 11.55 @ 119.0
put back front/rear seats and catback = 200 lbs = 1.5 tenths and 1.5 mph…that means 11.70 @ 117.5

So in 3000 feet of DA and ‘normal’ trim, this car runs 11.70 @ 117.5. Pretty solid for the shit DA.

I said 3000 feet because that’s what dragtimes DA calculator said for 3pm at MMP on July 30 I don’t care what APR’s toy said. We always use dragtimes for an idea of what’s what.
http://www.dragtimes.com/da-density-altitude-calculator.php?temperature=98.2&rh=46&altset=29.91&elevation=160&track=3&month=7&day=30&year=2015&time=2:58%20PM

Let’s ‘correct’ it to 0 feet. That means 3000 feet = 9% power loss of the claimed 500 WHP (we’re pretending it makes 500 whp because it’s fun to pretend marketing is real).

That’s 45 whp, and that’s good for 4 tenths and 4 mph. At best…shaving tenths and adding MPH in the 11s isn’t the same as it is in the 13s but again, let’s pretend it’s accurate. Also these cars are running race gas and a cooled charge, but let’s ignore it and treat it like an NA car, helping the stage 3 car’s case.

So 11.70 @ 117.5 turns into 11.30 @ 121.5. Compared to the fast stage 2 cars at 0 DA they run around 11.65 @ 119 MPH. So the stage 3 kit is good for around 3 tenths and 2.5 MPH.

In a race from 0-120 mph that would be 3 car lengths. Here’s what 3 tenths looks like in the quartermile

In a street race from 50 mph to 130 or so, that would be about 5-6 car lengths or about double the vid above.

This makes lots of assumptions in favour of the magnusson kit. Will be interesting to see how close this is to reality. If the stage 3 car wins by less than this margin, it means the standard $10,000 kit is really not adding much at all. Will be interesting to see.

Now I am not sure how or if it is different with AWD cars but you may see a slight increase in MPH due to regular tires as normally on RWD cars slicks can rob a little MPH but usually that loss is more than made up with the faster 60’…again not sure if that applies to AWD platforms

Thats the best attitude going in. If nothing else its something new and cool to play with. I think the story will be more clear when boost numbers get talked about more and more. After all 18lbs of boost on a stock 1300 blower and 18lbs of boost on a 1700 blower are going to be around the same CFM the charge efficency will be the difference. I think you could have milked more out of the 1300 but it will be interesting to have the really performance orented guys get behind the 1700 series.

Not that it matters but my thoughts so far are not good from what we have seen. But to also add. APR has been honest about how the car was run and for that good or bad you have to give them some respect. In the Rs4 game one of the troll companys got caught lying about there boost levels then the interior parts of the car and then the exhaust. The 1700 is a much bigger blower then the 1300 so right off the bat you will loose some of the power to drive the bigger unit and then again it will take more work to move the rotors. The real gains wont come untill you out CFM the 1300 unit and the real question is can you do that enough to make more power and still keep the motor alive and can you make enough CFM and still keep the heat down.

While the current results dont seem impressive I think the project is getting a real shot in the arm by you and the other few guys that are getting the kit. Sometimes all a kit needs is some real technical support and hardcore guys to help get over the hurdles. I know I will be following your guys results and am happy you guys are here so we can get data and good information without pages of Azoo interuptions

Justin, Apprecaite it! I think we’ll see 17-18psi with the standard pulley and 20-21psi with the upgraded pulley…

Arin alluded on facepage that someone has run better than their time, I believe it’s in reference to the 11.3x not 11.1x time but I don’t have any details… I’m sure they’ll get posted soon… Honestly, surprised someone took it to the strip but good to hear and glad others go this route… Hopefully, they grabbed some logs while making passes?

I didn’t get an update yesterday so I’ll check today to see what the status of my blower is?

PSI is over 18 on the standard pulley on pump I’ve seen everything from 18.1-18.9 on my gauge

Richi, Good to know… Have you done any vagcom logs and pulled boost there?

No, im getting my numbers right now from an analog boost tap on the p3 gauge, the boost plate is post throttle body pre cooler
