    RHD Super RB EVO customer goes 10.775@128.85

    Not a real common feat for this platform, especially on twins and stock'ish powertrain, while full weight. Even more so unique is that I believe this maybe the first RHD car to ever hit 10's period? (That is of course barring those running power glides)

    At any rate great short times helped this one along, but still pretty deep into the 10's so it is not like it just eek'd it's way in there in the process. Back to the OE'ish power train and full weight category, this is the 2nd quickest 1/4 ET I recall ever seeing... but it is open for discussion as well.

    Anyway here is all of the information that was provided, including the timeslip, below.

    "Stock internals
    Twin Super RB Evo 17T Turbos
    VTT inlets
    Fabricated my own aluminium outlets
    VRSF 7.5" Race IC
    ER Charge pipe with twin Forge DVs
    Fuel-it Stage 3 LPFP and PI
    Bimmerlife coils and NGK 95770 spark plugs 0.022"
    AR catless downpipes
    Exhaust is stock apart from 200cpsi secondary cats
    Custom tune from BQ Tuning using MHD
    Transmission is a Nizpro upgraded ZF 6HP21 with Stage 3 xHP tune and stock TC
    Modified M3 diff fitted with 3.25 ratio gears and E36 LSD
    Mickey Thompson 275/40R17 ET Street S/S tyres

    https://datazap.me/u/coupes44/datalo...54&tmax=908.41

    Technique is transmission in M mode, launch in 1st gear by steadily bringing revs up to as much as the brakes can hold and then go. I use the hand brake and foot brake on the line. I use the paddles to change gears."

    Great time. My RHD 335i did 10.755 with 131.86mph terminal- Full weight .that was a few months back . Pure stg2s and the mighty Nizpro trans too. Was tuning the car with twistedtuning at the time with flex fuel. So still more to go.

    Thanks for this but I'm going to move this to another thread. This thread is about the RB result.

    It really shows the nizpro works compared to others.
    Even stockers got in the 10s with that trans

    No reason to move it as far as I'm concerned.

    Good stuff. Very limited RHD group here then, perhaps the only 2 in the world, certainly the only two I've heard of myself.

    I know the RHD guy mentioned in the OP has been at this for a while- it was not an easy feat for him. He is usually running 11.0-11.2 @ 131-133mph. On this pass he nailed that 60' shut, which got him the ET, but he did get some sort of limp on the back end of the track I heard, but still have the momentum to keep on a good ET (could've hurt the trap a bit).

    All in all your setups are very similar, not sure the boost you were running, but more than likely around 27-28psi like the OP. Either way once again congrats, not an easy feat!

    It really went 10's? I thought that Nizpro car went like 11.0 or 11.1 sec on the OE Turbos? Regarding the Nizpro trans working, while that maybe true, both of these cars would probably be in the low 10's with another trans such as the 4L80E or the like.

    Was the 3.25 gear chosen just to be better than the 3.15 and unable to get to a 3.46?

    As stated above, the E92 M3 diff has a E36 M3 LSD which has been modified to fit. This was installed by a business called Diff Lab which is located in Brisbane, Australia. With this LSD, various gear ratios can be installed that cannot be with the standard M3 LSD. Initially, I had 3.45 gears installed but to avoid revving the engine out to 7,000 rpm in 4th across the line, I got these replaced with 3.25 gears which has the car going across the line at around 6,400 rpm. Mike at Diff Lab is of the opinion that the modified E36 M3 SD is stronger than the E92 M3 LSD.

    I think you are right Rob. There might only be the 2 RHD , not counting a couple of guys with single turbos.
    I was running 24/25 psi .

    Horrible timing (corrections)? Must be robbing a lot of power... Running pump gas or what?

    Good eye. Just skimmed that log and it doesn't look good, would've been interesting to see this pass on all cylinders.

    RHD full weight E92 335i with Super RB Evo N54 hybrids (and Nizpro trans) goes 10.7@128 in the 1/4 mile

    Not a ton of 10-second RHD hybrid results to report but this is great to see. BimmerBoost members in the United Kingdom as well as Australia in particular will take notice of this result on a full weight E92 335i and of course the Nizpro upgraded automatic is helping that elapsed time.

    I agree with your comment on the timing corrections. I wish I knew how to get eliminate them or at least reduce them. Dimitri @ BQ Tuning has been trying from his end. Certainly, the trap speed is less than it should be. I had another 2 runs last night. On the 1st run, I tried a 2nd gear launch with no success. After launching, it automatically changed into 3rd at 3,800 rpm which killed the run. Got a 11.159s @ 127.78 mph. On the 2nd run, I did a 1st gear launch and managed a 10.927s @ 128.35 mph. 60' time on the 2nd run was 1.64s compared to a 1.944s on the 1st run.

    Again, what fuel do you use? Try to up your octane, get the best pump fuel and add some E...

    It's weird, you have way to much timing corrections for running full E85 in my opinion...

    Perhaps he is not getting enough of it to the cylinders?

    If there wasn't enough fuel going to the cylinders, wouldn't the lambda for each bank indicate that fact. The lambda appear to remain steady on 11-12.
