Bone stock M340i xDrive drag strip testing: 12.08s quarter mile

B58togo · 10-15-2019, 11:06 AM

^^ It’s the AWD hooking pretty well. I’ve seen Golf R’s run 12 flat at only 112-113 and also 11.7 at 115 or so. My RWD 240i on the other hand, is tough to hook. I managed an 11.8 @ 118 and then 11.9 @ 119. If I was AWD, I’d easily be 11.40-11.50’s.

My stock F90 ran .3 quicker then others that were posted.

Then she ran a 10.52 @ 132mph with ........Michelin AS3+ (all-seasons), just with Race Chip.

Do you have a time slip for this? No way your hitting 132 mph with only a tune, and especially a Race Chip tune. For comparison a stock GTR trap is about 125, my M3 with a proper tune was dead even with my buddies GTR. A dodge demon traps @ 135 as well as a Zr1

Track must be going downhill

I just picked up an M5 yesterday and can say in normal driving the M340 is quicker. If you hammer it at 40mph it gets to 60mph faster than the M5 (draggy verified). After that the M5 pulls way harder though.

Is this an f90 m5 you're talking about? I can believe that the m340i feels quicker than an f10 m5.

Bring your new car back to the dealership for a detune immediately. No 400 hp for you!

C/D got 129 on their stock F90.

Lol.

You'd be quite mistaken. Stand by I'll look through my F90 posts.

Yes, 100% legit on an NHRA track and All-seasons.

Here's a post from one of my first days at the track.. I'll find the 132 one... not that I need to prove much in this M340 forum... but I don't enjoy being questioned. Lol.

All in good fun... but yes, the Racechip did proved a significant bump... it's been well documented on the M5. Sorry your GTR couldn't keep up...

This isn't the one in question.. just first one I found real quick... still topped your GTR.

I'll look this evening when I get home for the other ones

ferizzo · 10-16-2019, 10:54 AM

whoa...what's that on the left going 13.9 @ 123??? 60ft is terrible so I imagine was spinning all through first! Or spraying since I see it was only going 84 mph at the 1/8th.

People talking about the detuning aren't just making it up...

According to Mission Performance, early M340i's had a "bug" in the DME and the car was making more horsepower than it should - to the tune of 400whp. In June, they released an update that lowered the car down to 346whp and in July they released another update that lowered the car down to 338whp. There was a recall on early M340i's for a fix for emissions which some are speculating is the re-flash that lowers the car back to the ~338whp.

Mission Performance has dynos to show the power loss from June to July DME's but not their claimed 400whp early versions: https://g20.bimmerpost.com/forums/sh....php?t=1638852

However there are a number of dynos for early Supras where the car was making ~360whp and underrated and MP claims the updated Supras make less horsepower too (and there are dynos showing the Supras making ~330whp) - so there's at least a little bit of evidence to show that there may have been some detuning going on. There are so many variables when it comes to dyno numbers (the type of dyno, the weather, the parameters the operator is using to plot the graph, etc) - so going from 360whp to 330whp could simply be down to DynaPack versus DynaJet dynos.

For example, Evolution Racewerks also dyno'd an M340i recently at 391whp / 421 lb-ft on a DynaPack. ( https://g20.bimmerpost.com/forums/sh....php?t=1655627 ) - I don't know whether that is a Pre-June flash M340i, a DynaPack that simply reads really high - or what. They say it is an early model, the first that Irvine BMW got, so maybe it is one of the 400whp versions? I dunno, Evolution Racewerks did say they were sent a letter for a recall but haven't applied it yet...

Whether or not 400whp was ever really a thing on the M340i's, who knows - it could be MP trying to sell tunes I guess.

No matter what though, a 12.08 1/4 mile is really impressive - especially on the runflats. I'm thinking the car could easily be in the high 11's with the Pilot Sport 4's?

Don't be silly. DynaPak is the highest reading dyno and you just simply can't compare dyno to dyno. Unless it's a delta between cars on the same dyno and really the same day, the numbers are not reliable measure.

Mission Performance has done nothing to prove their claim but will be happy to sell you a tune for your supposedly BMW detuned car. These cars are very fast and this nonsense is unproven and irrelevant.

:bs:

Mission Performance surely did the dyno testing on the same machine (and same m340i) and yielded a considerable difference after the car was updated. Did you read their post (link was provided)? Do you think they made it up?

I agree that Mission Performance showing that original dyno with the higher HP reading would clear all of this doubt....but until then, I guess I'm choosing to believe that they weren't making it all up.

Why would BMW do an update and reduce power? Maybe they realized the added power on every m340 being released would put too much stress on the engine and tranny to align with their computed warranty coverages/projections? Maybe they chose to save the extra power for a future MPPK offering?

Well they are probably doing it. A newer replacement m240i when mine was in repair felt noticeably slower with very slow gear changes with muted exhaust sounds compared to mine. However it was more planted. They felt like two different cars
