Got a dragy shot of that showing your splits? I'm curious where you're faster.

It was recorded on a Vbox but I've recently bought a Dragy so once the weather improves I'll post some times.

[chris-c]

Well you're still a fair chunk faster than me. Went out tonight and did a 8.68s 100-200.

The car is a rather overweight F31 340i with the optional extra electronic tow bar and panoramic sunroof adding even more weight.

Exhaust - MPPSK
Downpipe - VRSF 200CEL
Fuel Pump - B58TU
Fuel - Tesco Momentum 99
Tuner - BM3 OTS Stage2+
Drive - RWD
Gearbox - ZF8 - XHP Stage3

Im same as you bar i dont have the TU pump, XHP, run a 0CEL and use shell vpower
On the stage 2 map Out times are identical.... both 0-60 and 100-200!

Iv since changed over to the TU pump and Stage2+ and although the intake temps were about 10oC higher my times didnt improve at all....

Cant wait to try some more draggy runs now the weather is cooling off.

I've now managed an 8.68 for 100-200 so knocked a bit off.

Ye i feel the cooler wet weather will be playing a part now! Il give it a bash in a few weeks when im home and report back

[chris-c]

Okay got it down a fair chunk more.
This'll do for now. Getting wheelspin like that at 60mph had me worried.

[trescuarenta]

Almost there! Hunting for the 340ix stock turbo 1/4 mile record, currently owning it afaik but no valid 10 sec yet.. so close.

What settings do you have the car in ? Sport+ or DSC off fully? Comfort sport or M shift and if M when you shifting?

Good time that!

[T_H_O_M_A_S]

Car is catless and opf delete
runs on MHD stg2 93oct

corrected time would be 7.716

[IMS-340C]

Mate 100-200 in the 7s on 93 without Ethanol is incredible

Any logs ? Also what do you mean by corrected time ?

He means corrected time recalculated for 0 slope. There are apps you can use to do so. Quite useful as in reality you never have 0,00 slope.

[IMS-340C]

I guessed so but 0.76 slope is worth much more than 0.1 seconds.

Also how is slope correction calculated ?

No, apparently it's not I seem to be using a different calculator than him as mine has 2 decimal digits, not 3, and still it calculates the same - 7,72.

[IMS-340C]

In real life with 0 slope I bet his car will run 100-200 in 7.5 seconds.

I've done too many 100-200 Dragy runs and in my car a 1% slope is worth around half a second 100-200.

Here are 2 consecutive 100-200 runs on the same road with different slopes.

In real life the slope makes much bigger difference than your calculators guys.

thanks , this is a log from the same map , but different time frame

What fuel?

I don't think 98RON/93 octane.

Maybe 102RON fuel on the 93 octane map you could get good ignition timing and 100 - 200 time of 7.8s on that map.

Looks more like an E30 result, still good either way

[B58togo]

Over here in MPH land, had a couple 62-124 mph (100-200 KPH) in the 7.6x realm, but they went blank/invalid? My 8.78 second 60-130 time held up though. Cooler temps help a ton! I'll get new 62-124's tomorrow night.

it is on 93 oct , as its the best i can get on pumpgas overhere
i always thank esso's , but esso or total or shell , dont think it would make that much of a difference .
later on i will test the e30 and hpfp maps aswell .
temps were cool though , around 10 degrees C

Good time that!

DSC fully off, stick to the left. I start with kickdown then manually change up.

Actually, those 2 times corrected for 0,00 slope result in 10,28 and 10,44 s respectively ... Those are close times. In my opinion this proves the calculators are quite accurate.
Of course the bigger the slope, the bigger any deviation. So a calculated correction does not fully compensate for an uneven terrain. It just mitigates.

Keep in mind that the slopes Dragy displays are not 100% accurate either. I do all my runs on the same road (back and forth) and the displayed slope varies more or less every time. (verified with different dragy units)

None of this is precise science I suspect 100-200 runs are by nature much more prone to inaccuracies due to the significantly longer distance driven (in comparison to 0-100).

Cheers! What RPM are you roughly shifting at? letting it rev right out or short shifting?
