Results: Stage 2, B58 (X3 M40i)

[Ekliptix]

2019.

The upgraded BWM fuel pump comes standard in newer B58 cars. In my model year, it’s a limitation.

Did you lower it with springs or coilovers? The drop is nice @Ekliptix !

[03ozwhip]

Nice numbers. Hows the ride quality with those springs?

[Ekliptix]

It's just H&R springs. The ride quality is the same as the stock springs. It's a bit firm, but apparently much more comfortable vs the more sporty X3M Comp car.
I'm also on runflat tires. It'd likely ride even softer with non-runflats.

Looks amazing

E85 should absolutely net you well over 20hp/tq as long as there are no other bottlenecks. I got nearly 100hp and ~80 ft-lbs (532 to 623hp) on my Nissan with all support in place. Going from Petro Canada 94 to 17th Ave E85

Drove 500km to BC today. 7.6L/100km going 10 over. My previous best was 7.3l/100km for the same trip when the car was stock. Could have just been wind, causing the difference. Or the tune, who knows?

Still happy getting 31mpg and running low 12’s in a suv.

I want one more and more I see yours. But I made a vow to my wife to not buy another new car lol

2 more 'bests' this week.

Sub 4 sec 0-60. Finally got launch control figured out. Roads were slightly damp, so may be more there.


And 500km from sicamous to Calgary on Monday. 33mpg driving like a granny.

[dirtsniffer]

that's incredible!

[jutes]

This is a pretty good vehicle.

[bjstare]

Amazing.

This thing may be the perfect all arounder

Great looking X3! I have a stock 2019 (Alpine White) X3 M40i and love it. We just did a 750 KM return trip to Wasa Lake and I got 6.9L/100KM in Eco Pro with my wife, 2 daughters and our gear on board. I also managed to get 57.3 KM in extended range. The B58 can be unbelievably efficient when called upon, such a brilliant engine. I see your X3 and I keep telling myself I need to do the same performance upgrades.

[Ekliptix]

That's spectacular mileage!! You can come drive mine if you want a preview. Just PM me.

FK510s are a nice budget tire. How do you like them?

[Ekliptix]

No complaints so far. Mainly highway driving. I'll need to do a new launch with Draggy to see if there's a 0-60 improvement.
Compared to the runflats, they are more comfortable, in part maybe due to the taller sidewall too.

The price was amazing. $1,700 shipped for all 4.

[LUV2REV]

Thanks for the generous offer, would love to go for a spin! I'm running Continental Extreme Contact DWS 06 Plus on mine, such a huge improvement over the run flats in every way. The FK510 will serve you well.

[Ekliptix]

I'm adding a stock supra fuel pump tomorrow. 30 min job, it's right on top of the motor.
Then doing the next flash ("stage 2+"). Supposed to yield +60hp and +134tq on 93. Hard to believe, but we'll see.

Then I'll be shooting for a 11.99 on the street with dragy. We will see!

Is it time to line it up with the Trackhawk yet?
