Hi There ! What boost settings are you using for your map 6 to produce that rather awesome power figure? My Pure stage 1V2 arrive next week. stage 1 V2. Run 1 was with my custom map 6. Run 3 was with map 5. I imagine a couple more runs with map 5 to let it adapt would have netted more power. I would say Im very happy with map 6! 425 WHP AND 427 WTQ!!!![/QUOTE]

Just to inform you guys, you wont necessarily see higher boost with a non stock fmic. I saw 2 psi less boost with the forge fmic over the whole range resulting in 0.5 sec lower 100-200 kph than with stock fmic. Keep in mind i have meth to cool iat as well. With hot outside temps the stock fmic heat soaks when doing multiple pulls after eachother. Even with meth.

Now with the wagner competition fmic i see similar to slightly lower psi (0.5 psi) than stock fmic but no heat soak ofcourse. 100-200 kph i dont see much difference with stock fmic when doing just 1 pull.

Justed wanted you guys to be aware of this. Above is valid when running turbo at max boost (pwm 100%) so it cant give more to compensate for pressure drop.

I have yet to find a fmic that cools better and has better flow than stock. If no meth the iat gains ofcourse are more important than pressure drop.

[ShlemonboostedM]

Pressure drop isn't a bad thing .. And I can't believe u lost power with Fmic .. ?? I gained around 13whp and pulled much harder top end with my intercooler installed on stock turbo .. The flow alone should of helped on upgraded turbo .. The stock tin-can is just horrible, heat soak in half a pull .. Maybe it works better for you thought I don't know ..

[CombatNinja]

It is completely logical that a larger aftermarket intercooler would see a pressure drop. Why are people having trouble understanding that? On a single dyno run on a non-heat soaked car, the stocker would probably show a better number. Check back after multiple runs with no time to cool to see the benefit of the larger intercoolers. Bottom line is, unless you live in a very, very hot climate or track the car regularly or spend every weekend at the drag strip, you probably have little to no need for an upgraded intercooler. The occasional blast up through the gears to double the speed limit on the way to work does not warrant some kind of huge intercooler. Darkhold is obviously one of those exceptions where he is pushing the "Stage 1" incarnation of this platform to the limits. He has traded a bit of pressure drop for repeatable, consistent performance run after run.

100% correct

For example:

John buys the PURE Stage 1 for $995.
3 months later the PURE Stage 2 is released
John returns his Pure Stage 1 and receives a $995 discount on the PURE Stage 2.

(you're basically borrowing the PURE Stage 1 until the PURE Stage 2 is released)

Make sense?

This is awesome. Great to hear, because I will definitely be doing this

The PURE Stage 1 is designed to be undetectable from the outside. It's a wolf in sheep's clothing. It is very warranty friendly. The dealership would have to disassemble the turbo and start taking measurements to discover it was upgraded.

If we can narrow down power output with boltons and map2/5 jb4-no custom flash I think even more may jump in. Hah I'm one of those, what kind of boost can it support efficiently with map 5 auto tuning, especially later n55's : )

Honestly you want to run a custom map6 with this turbo. Because the base maps like map5 have boost targets in high rpm range that are far lower than what this turbo can do. Because the standard maps are based on stock turbo.

Can we all share a custom map or does each car have to have their map 6 tuned individually. It would be nice to have quasi OTS custom maps for these turbos. Would make me feel better about it for sure. Also do they require a back end flash?

There is a common misconception about the custom "map". It's not a custom map. It's custom boost settings. It's as simple as logging into your JB4, and specifying boost targets for 12 different RPM points (intervals of 500 rpm from 1500 to 7000). So the "custom map6" that people refer to means entering 12 numbers into your JB4.

I am tuned only by jb4 on my F series and its doing great.

A baseline map can be done as starting point. I believe running 14 psi from 3k to 6k rpm doing 13.5 psi at 6500 would be a good base to start from on 93 octane.

Depending on octane and user preference you can up the boost or create a bigger midrange etc. logging will show you what works well on your car.

On my car with meth and 30% E100 mixed with 70% 93 I can run max boost which is 20 psi till 5k rpm. 18.5 psi at 5500, 17 at 6000 and 16.5 at 6500. Thats what the turbo can max do on my car provided i have enough octane.

Oh cool, I thought we were going to have to remap the throttle position and air fuel ratios and stuff like I do tuning my motorcycle.

This makes life easy. Thanks for the info

I was also concerned about the timing adjustments but it appears that map 6 does that dynamically based off of the boost settings. Truly a brilliant setup, this is the fan BMW should have brought from the factory.

+1000 to PURE for figuring out this great return on investment. Excited to see what my car does with this setup - hopefully I can get it and install before the next battle grounds and i'll surely post up some vidz. it's sept 8th here what do you think pure

What is the time frame, e.g., when do you need payment? Very interested but need to make sure the timing will work as I have already signed up for a group buy for an LSD.

Once the list is full, we will be asking for payments. Early payments are fine as well. Once all 10 are paid, we will begin shipping turbos in order starting with the first person who paid on the list.

Thanks

Okay. Put me down. At this price point, I'll find a way to make it work.

Were you able to get around to a DIY for us? I ordered and am debating installing myself or not. Maybe with @JETmn we could do them together?

Also, you have every mod I do. Would you mind sharing or PMing me your map 6 settings? Very impressive results you got! Due to the extended power range, I assume map 6 works better with this setup than a Map 5 or Map 7 does?

[eyim1988]

Would the 2014+ upgrade work for the f30 with the prior turbo? Im assuming it would make even more power. It might just be a dumb question

[.mark]

Would it be possible to post the install guide? (Assuming there is one). I'm a DIYer and fairly mechanically inclined, but would like to get eyes on what I'm getting myself into. The last few times I've been under the car, it seems pretty tight.
