Pure Turbos N55 single turbo upgrade

335iFFM · 01-18-2014, 06:48 PM

Nice!

That's what I wanted to hear

evo335xi · 01-18-2014, 07:35 PM

But a back end flash would be necessary correct? Jb4 will make the power with boost but the air-fuel/timing would not be able to be controlled?

J_Vang · 01-19-2014, 09:49 AM

This is so exciting. Keep us posted!!

Everfly · 01-19-2014, 12:39 PM

Cant wait

marCOCOpuffs · 01-19-2014, 02:19 PM

When will tuning/dyno be complete?!?

PeterPure · 01-19-2014, 04:22 PM

Well I guess what N55 guys need is being able to go to 6.5k rpm instead of having to shift at 5.8k. I would be looking for an upgrade that does above and gives me 50-70 hp over jb4 map2 on 93 octane.

And all this on an F series car

Oh boy...

Agreed. Its nice to have the power on 93 octane. E85 is good but a pain to get sometimes!

Any word on this upgrade?

ze_german · 01-21-2014, 05:46 PM

Why exactly wouldn't the Cobb AP work for this mod? Get a protune on a dyno and go. I don't see the problem.

335iFFM · 01-21-2014, 05:57 PM

Because COBB doesn't support the N55s built after 03/2012. BMW has protected the DME with a TriCore Security Setup.

marCOCOpuffs · 01-24-2014, 02:37 PM

So what happened here? Vargas and Pure's posts were deleted and no updates

Some of those posts had solid information though. Still don't see why they got deleted despite the high levels of sarcasm. Interested to know about the truth behind the VTT upgrade regarding the possible reverse rotation "issue", several comments were deleted including Rob's and other forum members.

JETmn · 01-24-2014, 04:36 PM

I am guessing VTT threatened to pull their business if PFT aired "dirty laundry" like the wrong threading on the reverse rotation shaft. Pure speculation on my part.

marCOCOpuffs · 01-24-2014, 04:42 PM

There's another post on bimmerbuuust. Idk... Don't really care about the beef. Just want to know about the results

Yeah, that was me. Can't stand that board. Long live E90!

335iFFM · 01-24-2014, 07:37 PM

As far as I know "someone" stated that the reverse rotation shaft @ the N55 Stage 2 Turbos from Vargas aren't made properly so they - may or may not - be likely to fail.

Pure Turbos:
Really excited for your turbo. Any updates?

We recorded some datalogs on our customer's Stage 1 car, and they have been sent to Terry today. So tuning, then dyno...

We just bought a '11 335i N55 shop car. So we will provide more results once our Stage 1 turbo is also installed and tested on our shop car.

335iFFM · 01-28-2014, 04:50 AM

Nice!
Really hoping for a better top end

FWIW: Our customer with the Stage 1 turbo said:

"The car has so much !@#$ing balls on the top end even on map two. Raced my buddies 09 GTR with intake and exhaust and walked him. Used to barely keep up with him."

This is no result or data of any kind, but it got us excited when we heard it. It sounds positive so far...

N55 GTR killer... Hmmmm. Sign me up
