    • BMW Tuner forum fight - RK-Tunes accepts Vargas Turbo Technologies $2500 bet over N55 output record

      Well, things are heating up in the BimmerBoost BMW forums with a bit of tuner drama. You may recall a recent article about RK-Tunes setting the BMW N55 power output record and to be perfectly fair BimmerBoost called this a record and not RK Tunes.


      If there is a higher output stock internal N55 out there, it has not come forward. No built motor examples showing higher output have come forward either.

      Yes, this 'record' was set on the RK Tunes Dynocom. VTT immediately objected to calling this a record:


      Different dynamometers read differently. We all know this. BimmerBoost even covered the Dynocom vs. Dynojet debate in an article previously.

      Tony Vargas of VTT continues to state the Dynocom is reading much higher and he may be right. RK Tunes states their Dynocom reads surprisingly close to the Maximum PSI Dynojet.

      RK Tunes accepts the $2500 bet made by Tony Vargas on the BimmerBoost forums:


      Who will win? Who will lose? Will someone back out? Tune in to the BimmerBoost N54, N55, and N52 forum section to find out.

        Bet stands, its very simple. My wording was clear, he puts it on a dynojet, and it will not hold the N55 power record. Rules to prove this known cheater does not try to cheat again.

        #1 Video of the run
        #2 Log of the claimed record released showing timing and boost. This stops again the known cheater from cranking everything to the moon for a glory run to try to match his inflated numbers. Same boost/timing for both runs. This will show the true difference between his Dynocom, and a dynojet
        #2 All dyno files made public. NOT screenshots NOT screengrab DYNO RUN FILES. This way we can all see exactly what the conditions were, etc.
        #3 Correction factors the SAME across both dynos meaning SAE on Dynocom, SAE on dynojet.
        #4 Money is given up front to a mutual account, or holding so no backing out.

        If he holds the N55 power record on the dynojet after running it, he wins the bet, if he does NOT, we win the bet. Simple

        Lets do this

        This certainly is a good point for both parties to establish in advance...

I have literally $2500 I would put as a bet, put that car on a dynojet, and it does NOT hold the N55 record. Put your money where your inflated dyno numbers are Jordan... Tick Tock
        In case anyone missed it. That was my bet, and is my bet...

        The question at hand is then in Tonys head of dyno knowledge what is the N55 record? Establishing this in advance would remove the variable of "Not so fast, I got this email from Russia last year where an N55 made 852whp which is definitely the record!" (or the like) if they do in fact match their own prior Dynocom power level within 10whp.

        So if I’m understanding this correctly he simply has to come within 10hp of his previous dyno results on the Dynocom?

        That would be pointless. It should just be a bet to beat the record. Period.

        $10 says this never happens because people will never agree on the rules and the records etc.

        If VTT is requiring all that for the RK tunes run we obviously need the same from whomever claims the N55 world record. I guarantee we will not get that. Which makes all of this a waste of time imo.

        To be honest tho, who cares about the n55? It is a bastard child and should be treated as such.

        Could we or anyone establish what the N55 power record actually is?

        I've had people say 680 or so is not the record for a stock internal N55 or overall N55 so what is then?

        As I understand it, he is going to video the run and make it all public so we should be good to go.

        Ok but if it makes within 10 whp of the Dynocom that then is the record, right?

        the highest i can recall is 652 sae on a dyno jet by jeff@speedtech https://www.speedtech.com/bmw-n55
        They have a 9xxx series efr kit for the n55, so that'll probably be the benchmark when results come in.

        Tony: I bet that this is not a record.
        Jordan: I bet we will be within 10whp on a dynojet.

        Yeah this bet is not going to happen.

        Well the whole purpose of the bet is to confirm the Dynocom numbers, right?

        Really just boils down to which angle of the argument this bet is going:
        1) Does this Dynocom provide as real world #'s as a Dynojet? (RK Tunes bet/argument)
        2) Is this example going to be the N55 HP record on a Dynojet? (VTT bet/argument)

        There needs to be some alignment established in the argument for this bet to ever have a chance to commence.

        Here is the thing. Its a suckers bet. We all know temps, humidity, blah, blah, blah affect the dyno readings. To come within 10whp on a different machine, different elevation, different temp, etc Tony is more thab likely going to win the bet. Regardless if RK sets a world record, he would still lose the bet with VTT if he is 11whp plus or minus. Thats why VTT probably wont bet for a record, only the 10 whp difference. Which is a safe bet.
