    • New overall BMW E9X M3 1/4 mile boost only record set by Active Autowerke supercharged E90 M3 - 11.2@126

      Congratulations to BimmerBoost member akh23456 and Active Autowerke. Akash's E90 M3 with DCT and the Active Autowerke Stage 2 kit with meth injection set the new quickest boost only 1/4 mile time with a run of 11.2@126. The quickest/fastest overall E9X M3 time was set with nitrous so this is now the quickest run with boost only. Even more incredible is that the record settings runs were done on street tires. 10 second car with drag radials? Certainly a possibility.

        I feel like the M3 has much more response down low. Likely just a placebo effect on your part.

        The crank numbers don't really mean at all that much, all that matters is what gets to the tire.

        Well don't dyno numbers represent what kind of torque gets to the tire? Supercharged M3 ~360wtq Modded 335i ~500wtq.

        Maybe someone could overlay a Supercharged M3 dyno graph with a modded 335i graph to comprare..? I will but it might just take me longer them some of you, lol.

        Sticky, torque numbers at the wheels are obviously related to gearing...this is why everyone dynos in a 1:1 gear (4th gear on the N54 6AT/6MT) to avoid gear multiplication related discussions...given say an RB N54 and ANY of today's S65 M3 FI setups there is no gear where the S65 will provide more torque at the rear wheels...if you feel/think/know otherwise please share the data and I'll do the same

        That is exactly why they dyno in 1:1. Im on my phone so I wont lay out the math right now as I am going drinking and need to make sure I am sufficiently hung over tomorrow to not pay attention to whatever family members will be yammering about.

        I know that's why they dyno in 1:1, thought I said that lol ok whenever you sober up post up what you've got, i'm genuinely interested as i really don't see it...cheers Click here to enlarge

        Im not drunk yet, im trying to get there. I know, I mentioned the 1:1 agreeing with you. Maybe you are drinking? Hah

I test drove a 2009 M3 a few weeks ago and it felt like it had nothing to give below 5k rpm, where as my car given it is modded will just jump sideways at 2k rpms and pull hard to redline. So whether or not the M3 mathematically makes more torque based on its gearing it just seems to not make a difference at low rpms.. right or wrong? And based on dyno numbers I see that most blown M3's put down around 360wtq and a lot of 335i's are close to 500wtq don't these numbers mean something?
        no, your right, for some reason m3 guys feel they have to say 360>500 just doesnt make any sense. the tq #'s are what gets to thr ground, thats why its measured in a numerically higher number.. if chaning gearing doesnt affect dyno #'s, then how does and me apply more tq to the ground? simple, it doesnt. he tries to be like pencil geek and overhtink things Click here to enlarge

        Calling me pencilgeek is pretty damn insulting. That is way below the belt.

        this is one of my best runs, overlaid with mikewads ESS 5.5 PSI (notice it only makes 48x HP, respectable) and then that same 5.5 psi with 100 shot of n20 (makes 57x HP, odd as some 7.5 psi kits claim this HP, so i guess 1 psi is 50RWHP on the S65, very interesting)


        Just note the TQ for sake of this argument Click here to enlarge

        **also just note that HP and TQ scaling is not equal on the chart**

        We arent talking about torque as read out by the dyno but at the axle as multiplied by the gearing and final drive.

        LM thanks for the overlay, looks like you are making "250wtq" more than that M3 @ 4500k rpm.

        thanks for that LM, i ain't touching the S65 but it does rev nice Click here to enlarge

        gearing wise the 6MT m3 has a slight advantage over a 6MT 335i in all gears except 6th lol its nothing earth shattering though...not sure about DCT or auto...however, given the amount of torque applied in 4th gear (from the dynos above) its clear that the 4th gear is close enough and that an RB 335i 6MT will put down more torque down to the wheels in each gear than an FI S65 even with that 100hp nitrous shot
