18% of 309kw isn't the same as 18% of 252kw :idea:

yes it was blue, nicolas Gp. if thats the case then my 1M is strongraise:.. would love to have a go with a stock e92.
Yes!! That's the same car I'm talking about. That car is from Lenz and is always at the drags. That car is modded properly so you should not feel bad about the result :thumbs:

sorry guys i run nicolas gp that same night, he told me he had a m-performance back box. so if you say that he has a ACS chip then its not working .
i have a stock m135i and when we ran there wasn't a half a car between us.
his car sounds nice :thumbs:

Does sound amazing. Were you driving the white m135?

Lol, I phrased that horribly... sounded much better in Afrikaans. If you calculate the power to weight of both cars at sea and reef the difference remain roughly 0.02 moving from coast reef.
E92 - 309kw and 1500kg - 0.206kw per kg
E46 - 252kw and 1400kg - 0.18kw per kg
Difference - E92 is 0.02kw per kg stronger at sea
E92 - 309kw - 18% = 253kw and 1500kg - 0.17kw per kg
E46 - 252kw - 18% = 206kw and 1400kg - 0.15kw per kg
Difference - E92 is 0.02kw per kg stronger at reef
I sucked the weights out of my @ss (as they remain constant)

I have raced an E92 up here in Johannesburg that some have argued was far from Stock, It only passed in late 2nd or 3rd from the line. (never had a rolling run) and the guy really knew how to drive his car.
I have raced an E92 in Durban and was in-front till we tap off, all comes down to driver and the car itself but mostly the driver.
(I had a Z4MC)
A lot of people say the E92 looses more power up here at the reef compared to the e46, some have even tested and proved this according to what I have heard but the physics behind the logic says other wise.

Not sure if its 18% exactly but they should lose same % of torque nullifying losses as per kw calc.
I guess its not impossible, it would just mean that for some reason the E92 is not using maximum air available at reef altitude? Maybe the less dense air causes the E92 to run more conservative AFR's?

Two other things that to consider:
1) The 0.02kW calculated difference should be more exaggerated at the reef because the absolute variance has increased (13.3% at reef vs. 11.1% at coast). So the e9x should technically pack a relatively bigger punch higher up.
2) The vehicle weights used only differ by 6.67%, since vehicle weight is constant and is not separated by more than the power difference at altitude - the lighter car will still not be favoured by the change.
However, if using Crash Nemesis' power-to-weight values the e9x will weigh approx 1276kg and e46 1041kg yielding a dead heat - as suggested.

Let me know if and when this goes down - would love to spectate.
Wow a thread i can respond to...
i had the pleasure/honor of running a Vert version DCT.. from Rivonia towards William Nicol...
so we do rolling in 2nd... he was in 3rd and had to slow down a slight bit to allow the DCT to engage 2nd...
3 hoot's on the joining onramp... and shock inspired awe set's in as 2nd, then 3rd, start finishing up, and we are still neck and neck... the minute the V8 starts getting to the end of 4th... then you can see the terminal V8 power... but even at that... we where both closing onto 240km/h... and i was more than satisfied that i could still touch he's car with my hand...

What car do you have?

Spiro drives a bone stock e46 M3.
I did the calculation using online weight figures from a few sources, including the weight of my e46 M3, and the constant figure was +- 1490kg vs the weight of the e92 which I got conflicting info. Some reported 1595kg whilst a post here reports the e92 as 1680kg.
I went with the 1595kg weight as I couldn't believe an e92 M3 would weigh 200kg more than an e46 M3. How did I get the calculations? There are numerous power to weight calculators online, you just need to search, put in weight and engine power and you have your answer.
Floyd, all I am saying is, don't race one up here. It's not a true reflection of the e92. Go race one at he coast, and if you beat it there, then man you have a fast car.
Peace.

Hi guys... Where are these drags?
I'd love to come see some BMW's run.
I'd love to come see some BMW's run.
From experience a modded E46 M3(xhorzt, SW) might stand a chance with stock E92 M3 up to 180-200kmh at the reef, stock for stock the E92 wins easily, been tested a few times. In fact we had a S3 run a stock E46 M3 from 100 to 250 and the M is in front by a car, but the E92 was ahead by 4-5 cars. I have also used my TS as a benchmark on my E46 M3 as well as both E9x M3's and the E46 is behind against the TS but that changes against the E92, TS made about 185kw and 400NM ATW on these runs and both M's were stock.
When my xhorzt is back on the M, will try my TS again from 100kmh to 250kmh, TS is now making about 200kw and 440NM ATW. Will post the result in due course.
I agree the power to weight makes a difference on paper but on the road I had a different experience with my cars.
