May want to specify 100 kph for us Americans lol.

If that's true, you have the fastest stock G20 330i in the world!!! And I have the slowest stock G20 330i!

Here's a run from today. Normal 91 octane from here in California and a JB+ added. Actually had to brake just before the 1/4 mile was completed so could've gotten a better time. Definitely feel like she had more in in her so looking forward to more runs in a better area.

Was that with LC? And yes. Those numbers are good! I'm guessing my car with a JB+ would've done similar numbers. Plus gas there is shit. You can probably try some octane booster like boostane (I've tried some other brand and it did nothing). Or a gallon or so of E85 if available.

At what position is the dial on your JB+? Not max I assume since you're handicapped by fuel quality.

Did a run with summer tires on, but it's still very cold here, 6c. There's hopefully a couple more tenths in this car with warmer weather.

Stock car? I've noticed that non American 330is are pretty fast compared to stock. All the American cars I've seen are slower than their European counterparts even though science says it should be restricted because you guys have OPF and we don't.

No I'm in Sweden. The car is stage 1 tuned. Thing is, I took the car to tuning shop with winter wheels on. They were 4x 225's and they kept struggling with it for three days because the ESC was choking everything they did.

In the end we agreed that I would take it and then get back to them after I tried with summer wheels. They're the usual staggered setup with 255's in the rear and now I have zero issues with the ESC.

I can't decide what to do now. On the one hand I'm considering taking it back to see if they held back at all - it's pretty slow off the line for a stage 1 tuned 330i. But on the other hand, the car feels so satisfyingly agressive and fast in the 60-120kph range - basically the winding back road sweet spot. I don't want to lose that for better 0-100 performance, I don't care that much about it.

But I'm going to speak with them and see what they have to say anyway.

Yea this was with LC. Feel i can try again with better traction and less fuel to see how it goes. Will do a few more runs with 91 octane then ad some e85. I'm confident that it's the fuel mostly holding it back. California sucks for that reason.

Oh yes. I remember you saying your traction light kept flashing? Or was that someone else?

And honestly. 0-100 isn't a major issue for me because of where I live. If I lived in Asia (say, like India for example), if be more into 0-100 runs because the average speed there is like 25-30kmph at most. We can't use speeds above 100-120 without worrying about our fellow road users.
My best 0-100 was 4.99s IIRC (0-60 of 4.75s). But the numbers that matter more to me are the quarter mile and 100-200kmph (62-124mph) numbers. That shows how strong the time is. Though we can't legally do 124mph here. But still

One thing I've noticed is. My car doesn't get it's best time with less fuel. Logic says it should, since the car is lighter and stuff. Not sure why. But I've got my fastest times with at least half a tank of fuel. I know it isn't traction because my wheels don't spin unless the road is dirty (irrespective of quantity of fuel in the tank).
And you can add a few gallons of E85. I add around 3.75 gallons E85 and top the rest up with 93 octane for a full tank. Or 1.9 gallons E85 and 6.1 gallons 93 when I want to save some weight (that brings the fuel gauge needle to almost the 3/4th mark). You should be fine running 1-2 gallons E85 and the rest 91 octane for a full tank.

Hehe my man. Officially the fastest stage 1/1+ G20 330i in the world, dare I say?

I'm thinking of running 3-4 gallons of e85 to get closer to 93 octane with a full tank. Mine is a rwd so I noticed a slight traction issue with two runs but I'm usually able to get one pretty smooth run in.

Not sure it'll be able to handle 4 gallons of E85 (I could be wrong since I don't know how fuel trims work). Reason I say this is because, when I'm running closer to 4 gallons of E85, my trims are almost maxed out. Which is why I usually do 3.75 or in some cases, 3.5 gallons. But that's with 93. Not sure if you can add more E85 because your fuel is 91aki, or if trims don't depends on the octane rating. When I was running JB+, I asked BMS if I could run some E85 and they said they don't recommend it. They said they'd recommend it with JB4. A gallon or 2, or even 3 to a full tank might not be an issue IMO.

Trims is entirely flow related

Octane ratings don't really correlate with energy density (all petrol have basically the same energy density)

Ethanol has less energy density than petrol.

So long answer no you cannot add more ethanol with 91aki unless that 91aki has less ethanol content to begin with (in the United States all petrol can have up to 10 to 15pct ethanol I think but I don't know if Cali is different)

Ahh. In that case, not sure I'd recommend running 4 gallons of E85 since that will probably max out the trims completely.

Heard that the Dinan tuned 330i was hitting 135 mph on the back straight at Road Atlanta during the past couple of days of R&D testing. For reference, I watched a YouTube video of a stripped out E46 M3 not even hitting that speed there. Granted, it was the one video I watched but consider me impressed!

I wish people with flash tuned cars would post more numbers especially BM3 OTS stage 1 people. Apparently there are quite a few but none of them have dragys. If there was someone near me, I'd definitely lend them my dragy for testing (with assurance that I'd get it back of course).

Hopefully the Dinan guys give us dragy numbers as well. I've seen dyno charts from most tuners but it's dragy or drag strip numbers that I'm interested in.

I'm about to go stage 2 with my Bootmod3 and catless DP, but no draggy 🙃

Oh come on!!!! Hehe hopefully you find someone near you had one

I saw a video of a stage 2 G20 330i on YT. They have posted dragy numbers in their description. I'll see if I can find it and then link it here.

Honestly that quarter mile time was achieved in stock form by a lot of the automotive journalism outlets. A stage 2 car making 350hp/360 tq should run better times than that. Also peak torque at 1500 rpm?

Yes. I even asked them if it was a typo and they said it wasn't. It's there in the comments.

I didn't even read the spec part. I assumed they were talking about the original specs. I just copied the description and pasted it here

Something is definitely wrong there though. My car does similar 0-60/60ft and 1000ft. My car even traps 3-5mph lower but my quarter mile time is atleast 0.6-0.7s better. This has been confirmed many many many times using dragy.
