Tuned M240i makes no more power than a tuned 340i, 440i, etc. They run faster times because they are lighter and more aerodynamic. They have smaller brakes, smaller/thinner wheels, smaller gas tanks, less potential options/electronics, etc. etc. That's why all of the tuners use m140i/m240i for their development and record-setting vehicles.

Regarding the race with the supra, the 440i is heavier, on some gaudy 20" wheels, also less aerodynamic, and less aggressive gearing than the supra.

And the usual reminder that the aggresive BM3 tune only makes your burbles louder. It doesn't make the car faster.

well, that's disappointing, all stock b58 (except tune) is faster in the same F30 xdrive body than FBO n55 + PS2 with stock hpfp. PS2 probably needs xdi60 to utilize it's potential fully.

Well I'm not surprised, stock b58 puts down 330whp stock.

My Ps2 on stock tune puts down 330whp stock tune.

I'm also PWG so I make about 20-30whp less than ewg does.

I'm also only using 91 octane only, so as you can see, I have no access to e85 and closest 93 pump is 3 hours away.

e85 mix would crash your hpfp immediatly. PS2 is way bigger turbo than stock b58 one, and I dont know why ewg ps2 should do more power than pwg one. now you’re limited on hpfp, and probably you run max 1.15-1.2 bar at high rpms to not crash hpfp? ps2 can do 1.5 bar up to redline easily, just xdi pump needed

EWG is easier to tune, PWG sucks to tune lol power comes from the waste gate shutting quicker or with more force or something, not sure why it makes more Power but it does.

PWG can mix up to E40, EWG up to E30.

Read again lol

I said it puts down 330whp on stock tune

It was the baseline before I actually flashed a OTS map.

meaning it's on the stock MPPK factory tune the car came with.

e30 or e40 depending on boost (load) not on pwg or ewg. This stupid myth that pwg has better holding hpfp came from times where ewg stock turbo crashed hpfp easily while pwg stock turbo could not do it. just simply pwg stock crap turbo can do max 0.7-0.8 bar at 6000rpm while ewg turbo can do 1.2 bar there easily. both hpfp units are _the_same_part_number_. So adding ps2 to pwg engine and turning up the boost it will crash hpfp easily on pump petrol only, not talking about E mixes.

I agree the Supra has higher 1st, 2nd, and 3rd gear ratios and also higher final driver ratio, but it's real life numbers that counts.

All the videos I saw stock Supra traps 108-110 mph in the quarter, surely decatted stage 2 340/440 trap higher.

You say "surely" but the info is out there.

Here's a guy on meth that only managed a 113 mph https://f30.bimmerpost.com/forums/sh....php?t=1633645

Meanwhile there are supras in the A90 drag group on facebook that trap 114-115. It just depends.

And at the end of the day, that 4 series is not doing itself any favors in the speed department. He clearly built it to be flashy.

The most consistent thing I can think of is caranddriver testing the Supra at 113 and a 440i at 109. Not considering any weight, gearing, blah blah, I agree that a stage 2 catless 440i should wipe the floor with a stock Supra. You're adding easily 8-10mph to a stock 440i which should sit at 118-120.

Again this is just what makes sense in paper but I think the stage 2 tunes need more track time. There was a user who did 118 FBO 340i BM3 I believe. That should pull a stock Supra reasonably.

because roll racing does not translate to quarter mile times/speeds. you can beat someone in the 1/8th and lose to them in the quarter. roll racing depends on where the speed is made and weight has a much more significant advantage.

ask that 440i what it traps in the quarter and i'll bet it's lower than you think.

I agree we won't know until we see some more roll races. I've seen completely different outcomes personally based on who hits first as well. For example my old JB4 328i pulled a n55 535i very easily but next run he got a good jump and I couldn't reel him in.

Another example, I got a very good jump with a Range Rover supercharged that traps 109 in a stock 528xi n20 and he couldn't catch me. Ideal conditions he'd kill me no question. So many factors.

See below: https://f30.bimmerpost.com/forums/sh....php?t=1615232

User beat out a v8 camaro and traped ~118mph on MP stage 2. Maybe the supra would pull on a roll but I find that hard to believe if this 340i pulled a camaro ss.

A lighter M240:



He wrote he has trapped 118 with this set up.

That exhaust system and even the MPE which is just a slightly modified muffler look very basic compared to the mppsk which had two valves. When both are closed one side is closed completely while the other side forces the exhaust gas through the muffler. When both are open it is straight pipe on both sides making it much louder. https://images.app.goo.gl/Q7gRqboH7ceRtbDx7

I mean, at the end of the day we both saw the same video. What happened, happened I've pulled on cars that didn't have appropriate gearing for the roll we did many times. I've pulled on cars that were faster, but they had big wheels and tires that dragged it down. there are a lot of things that can have an effect but it's no way impossible. who knows, the car could be a debadged x-drive. there's another 100lbs. It is what it is.

With average conditions my 340i with only MPPSK traps 112 mph on 88 octane.

Decatted stage 2 running on decent fuel should have around 100 HP above my car.

You're right. I guess the video is fake then.

So I guess anybody who proves you wrong is fake!!

Everybody knows a properly tuned 340/440 on good fuel traps around 118 mph.

Properly tuned lol

90% of people use OTS maps or JB4.

340/440i will not trap 118mph without meth also.

M240i will, but not the 340/440i.

Also you have DA, temp changes in most places as well. If it's consistently lower than 80F where you live with low DA, then yeah you'll run faster times with higher trap, but the avg places have high DA with temps ranging from 80-95F.

A FBO 340/440i on both mhd/BM3 here on 93 Oct have trapped a max of 114mph here where I live, temps were around 80-85F area at night.
