VTT N55 DBB Stage 2 spool log JB4
Just wanted to share a quick log showing the spool on the DBB Stage 2. The spool on this upgrade can only be described as lightening for a turbo of this size.
http://www.datazap.me/u/vargasturbot...log=0&data=1-4 10 psi around 2300 RPM 15 psi around 2600 RPM 19 psi around 2900 RPM For Comparison our N54 stage 2 upgrade doing a 4th gear pull as we did with the N55 10 psi around 2500 15 psi around 2800 19 psi around 3200 If we do a 3rd gear pull in the N54 which is more comparable as the AT in the N55 a much shorter 4th gear the results get even more skewed 10 psi around 2800 15 psi around 3100 19 psi around 3400 Basically the DBB N55 spools around 500 RPM sooner than even stock frame N54 upgrades. These turbos just plain spool! Also lets address these new claims of a stage 1 making 450WHP. Just to be frank, its complete BS the op was showing power in BHP. Terry Burger the man who holds the N55 record and also builds the software you all use to tune with, took a stage 1 to the dyno and found a max gain of 45 WHP, you literally gain that 45WHP over around a 750 RPM rev band, but we are to believe someone in Europe with some of the worst N55 JB logs (if we are to believe the logs the car is hitting 15psi at around 3250 rpm??) seen on the N55 made 450WHP which would be close to a 100WHP gain over stock. Plain and simple don't believe it, and lets be real, it is not a fact the numbers are BHP or crank hp. A stage 1 upgrade is good for a max of around 50WHP if pushed and pushed. This included ours, and it does so over a very narrow rev range, we are building one and we still conclude the stage 1 is the worst N55 bang for your buck. If you want to transform your N55 the only way to really do so is a stage 2. Happy motoring... Last edited by Tony@vargasturbotech; 05-08-2014 at 11:57 AM.. |

"N55 **** Stage 1 - 450WHP !!! Awesome update! Thanks Darkhold!!!" Then never corrected it even after other people were asking if it were BHP or WHP. In our opinion seems a little misleading, so we wanted to be clear on what to expect from stage 1 upgrade, we are in fact making one as well, so we would like people to have realistic expectations, nothing will get you upset customers faster then them thinking they are going to have a 450WHP car when in reality the highest we have seen a stage 1 N55 make is verified 395WHP. Just trying to keep the expectations where they should be. Thats all Last edited by Tony@vargasturbotech; 05-08-2014 at 12:18 PM.. |

Main reason I ordered your stage 1 turbo is for holding boost longer thats it..
I think the n55 hasnt been out long enough for there to be solid tunes that can handle big turbos. Even that guy with the blue 1er said its taking long to tune the VTT stage 2 on his car.. I also see rumours circulate that two companies are R&D their custom big turbo upgrade.. so I would like to see the results have that. Until then I'll be happy with just a compressor wheel upgrade that just lets me hold power until 6k. |

Unlike everyone else I know this turbo upgrade isnt going to make me hit 450whp. As a matter of fact I doubt I'll hit 410whp. I just hate having to shift at 5k as if im driving a old school muscle car... |

Didnt he get 395 peak out of the competitors turbo? 375whp is throughout the rest of the rpm band. Regardless you're right if terry only made a certain amount of power out of it doubt anyone else can come close to it or surpass..

Edit: I will say this though. Terry is not one to leave power on the table. The car he tested to my understanding already had a Catless DP to go along with the basic mods, so the only thing left really is a FMIC to finish the FBO. The new results we have coming in are from someone in Europe who is converting numbers from their dyno to what a DJ should read, thats usually pretty inaccurate, I think we can safely assume, you can expect from 45-60WHP over a 750-1000RPM rev range or so.

Im FBo and run 100% 100oct race gas all the time so maybe that'll help it a little as well. |

Its really that bad? So far I havent had any issues other than cracked radiator and clogged Dpf which is now gone.. shame because I love the truck since its a king ranch crew cab and extended bed.
What issues other than the HG blowing and possibly needing a suncoast soon, is there? |

We just saw the other guys upgrade gives you 50-70WHP. I guess they want you to ignore that fact the other only confirmed dyno with tuning from the creator of the tuning software shows 45WHP gains, and an unconfirmed BHP dyno in Europe showed a supposed 57WHP gain. But hey forget about dynos and that pesky stuff. It gives you 70WHP according to the marketing material. Gotta be a fact...

The dyno showing WHP is posted now. There is clearly a 70 whp spread at 6,000 rpms. Perhaps your eyesight needs to be checked? You know what's so funny about this? That is at least a single result that we have to go by that shows a 70whp gain. As already pointed out, your site claims your stage 2 turbo is a 500 - 550 whp turbo with ZERO RESULTS to back that up. And you're the one calling BS???? |

No my friend, it says supports 500-550WHP. The garrett numbers for that CHRA support 640BHP so yes our support numbers are accurate according to Garrett. Lets not forget they also told everyone it "made" 450WHP and when in fact the user showed 450BHP, but they never bothered to correct until something was said forcing them to. Big difference between quoting what a wheel combo will support and telling people what it made. So far ours has made 477 and holds every N55 stock frame record, but the wheel combo will support much more according to Garrett this is a fact, and not a number we came up with. I also find is quite entertaining they are taking a european dyno that reads BHP and then converting it to WHP and calling it gospel. Bottom line, until they get it one on a DJ and show 70WHP no one will know. Time will tell. Cheers

Different dynos. Your dynos read much higher than our dynos do. No N54 makes more than 430whp over here with stock Turbos in Overkill-Mode. Just for example. No car company will every use a Mustang or a DynoJet. They are just not accurate enough. MaHa 3000 LPS is the way to go. And these are the only dynos car companys accept ;-)
