Well done ///Mary!

[Sherwin@xcede]

Congrats to Ary ///M on doing 13.6 three times on an unprepped Tarlton Friday night into a stiff wind. All the regulars were 0.3-0.4 down on their regular times.

Last time out at Tarlton in the day, Ary ran 13.7 @ 166 on street tyres. Ary has CSL wheels, etc but the only power mods are chip & decatt.

Well done Ary, awesome time for Tarlton. I'm sure under more favourable conditions you can make an assault for 13.4-13.5.

Good times, what was the exit speed?

///Mary lol
well done Ary, good times :thumbsup:

 

[Xack]

It still amazes me to see these cars run 13s so easily, with no Big turbo conversions, no reprofiled cams, no Nos, not even Mr Wisceco or Mrs Pauter...jus M-power,its jus:dropjaw:...guys with hatches spend R30k-R40 + to get the same result :nono: ...:thumbsup::thumbsup::thumbsup: to the e46 M3...

Keep it up guys, Shawn, we'll be having a chat soon:thumb::thumb:

 

[George Smooth]

Awesome time. Should run a low 13 on a prepped track.
What tires was Ary using?

 

[AryM]

Was an awesome night out although...

There was a VERY VERY strong headwind pushing against the cars racing.
Wind started from Friday morning, was hoping it would stop by the evening but the closer we got to Tarlton, the stronger the wind was becoming.
:bawling:

Oh well, most of the usuals were down on their times by about 0.2-0.4 seconds.
So, I'm hoping in more favorable conditions,the low 13 second bracket beckons esp @ Tarlton.

Only has 5 runs as Tarlton as it was busier than usual.
13.71
13.69
13.82
13.64
13.60

Will update exit speeds as soon as it is released but some guys did say it was close to 169kmh-170kmh on certain runs!

Thank you Xcede and lay off the ///Mary bit.
It is Ary_///M
:thumbsup:

Car is consistent and beautiful to drive!

Yeah Georgie was a pretty good time & done on semi's. But for me it's not the time that's important, it's the speed. I actually get more excited for speed.

Last time in the heat of the day with 19" street tyres Ary ran 166. This time I think the trap was close to 170, pending official results. That's pretty decent trap & it show's on Motronix's dyno where the car makes good power.

Good for 13.3 maybe 2. You forgot to mention the 4.10 diff installed

Thats a very decent exit speed for a E46 M. I rate with the semis and staying on the throttle for longer makes on Xcede there exit by miles hehe. In the old days if you had to tell someone a E46 M could run a 170+ they would think you crazy.

No I didn't forget sir. I said POWER mods. Diff is a drivetrain mod. Not an enhancement done to the engine/exhaust/intake.

On Ary's car the diff is actually costing him a tenth on the standing start runs. He is making enough horsepower to pull the longer gearing & so is not seeing the benefit from a stop. On cars with lesser hp, a 4.1 can make a tenth or 2. A car like Ary's making strong midrange power a diff makes no difference. He ran 13.7 @ 166 in the heat at unprepped Tarlton with the stock diff on 19" street tyres.

Ok so I guess you are not using you “poor man’s supercharger” theory anymore.

 

[Sherwin@xcede]

Did you read somebody's mind or how did you come up with that statement? Where did I say that. Read my post again. I emphasised that FROM a stop or standing start it was not benefitting him & might even be hindering him.

Driving the car, & on a roll obviously the difference is huge & it feels like a poor man's charger. That doesn't change.

But when 2 cars stop at the lights, it's a great leveller. You know this. All gearing discrepancies, powerband differences, etc get thrown out the window. The 2 cars get to rev up to wherever they want go from the line. Shorter gearing then doesn't have an advantage when you start from zero.

So to answer you question, No. I am still using my poor man's supercharger theory. Just not for standing starts. Any questions?

Smoothie was ur take on the "poor man’s supercharger” theory?

Boned CSL reps makes the wheels turn faster n not the diff

No i did not read anyones mind, you told me this many a times. For once in your life please be honest.

Car is 6MT, launch was 3500rpm on both runs.

I have 25 runs with the stock over many visits there. I have only 2 runs with the 4.1. On only my 2nd launch ever with the 4.1, I bettered my 25 launches with the stock diff. Of course I didn't know that when I was there. It's only when you get home & download the data that can you see the times.(better launch meaning better 60ft meaning better 400m)

i dont want to be a bubble-burster, but this data demonstrates to me that it's definitely not worth it to get a 4.1 diff.

I disagree with that. I am one that has tried many NA mods. 2 carlengths from a stop (probable more from a roll) is a lot. To get that gain using horsepower will take loads of money, time & tuning headaches. Plus the car just feel so "alive" with the 4.1.

thats why i wont be modifying my M motor at all. there arent any significant gains to be had for less than the cost of a firstborn male. this is the only thing i'll miss about my b5s4... the same day i bought it i spent $700 on a spare ECU with a modest performance chip, and had a 28% gain in horsepower and 33% gain in torque =[m3 power + 1.5(m3 torque)]. it would cost 5 figures to get that percentage gain in the m3. i feel like this motor has already acheived diminishing returns from the factory when it comes to power... thats not necissarily a bad thing.

Great post!

Now I certainly won't be getting a 4.10 diff. What you gain between 1st and 2nd gear seems minimal. Also, on the track you rarely ever use 1st gear anyways.

awesome thread, thanks. the 4.10 diff is a worthy mod IMO but certainly doesnt provide quite the speed/accel benefits I was hoping for.. particulary off the line/lower gears. however it does seem people really feel the added 'pull' from the 4.10s.. i guess thats part of what you're paying for.

I was seriously considering this mod until I saw this post. I
definitely appreciate the information. If only every mod
decision was so cut/dry and could be backed up by no BS
data like this...

I don't think many people realise how much power is needed to make a dent on a Vbox run. On my '02 M3 I tried many mods. I even had Delage at one stage & it made only around 8-10rwhp. That makes almost no difference on a Vbox run (maybe half to 1 mph higher trap & 0.1 better ET). The only other mod in isolation that might make more than 0.1 & 1mph are the Schricks. I had exhaust with decatt, intake, ECU, racing oils, & Schrick 280/272 in the following dyno comparo to stock:



Base dyno is 299hp & after is 335hp. Here are the Vbox runs for a 30-odd hp gain:

Time to Speed


The modified car is traps 7 km/h higher (4.4mph)



After 14.75 seconds the modified car is 14 metres ahead, which is just about 3 carlengths (M3 is 4.5m in lengh).

So for 35RWHP gain you will gain 0.3-0.5 ET, around 4mph trap & 3 car lengths.

I think the diff is serious bang for buck then & I've tried just about every mod (except supercharger).

[Sherwin@xcede]

Wow, so many people posting it's not a worthwhile mod.

So Darren let's tackle this. 1stly I don't understand why you say I am being dishonest. I take offence to that. I am posting my opinion. I think you like to look at everyone's time & compare to yours because you are a driving god. So anytime anyone one runs a good time you need to add your 2 cents to put it down.

So let's tackle the dishonesty. That data was for my car. Each car is different. Do you agree? Or do you think each car is identical?

We get a lot more gains than anyone else on the S54. And a lot more than people used to get in those days.

A diff is masking a deficiency in the mid-range torque. On my old car's it helped.

On Ary's car, he doesn't need help. He gained almost 30 wheel hp in some places with my map. He has the thrust to pull long gearing. My car didn't & hence the diff made more of a difference to me.

Of course on a rolling start the diff will still help Ary. I am saying on the standings it may well be a hindrance.

So enough with the dishonect crap, it's getting as tiring as you bragging about your driving skills. I am posting my opinion based on personal experience, logging, Vbox, etc from owning these mods. And I am saying Ary's car is losing ground on the standings.

You can disagree with me if you want, & present the reasoning why. But brining out the dishonesty bull is not called for when I am telling you my findings for this particular car.

Peace.

 

[50/50]

"Dishonesty bull" - "HAWK" :slap:

 

[Sherwin@xcede]

You know what. I just realised I posted this earlier on in this thread:

On cars with lesser hp, a 4.1 can make a tenth or 2.

Now here's my time to distance graph on M3forum a few years ago:

A total of 8 metres ahead. A M3 is like 4.5 metres long I think. If I'm being dishonest then correct me, I'm not sure.

So 8 metres is just under 2 cars. I think the average will be 1.5 cars. That's between 0.1-0.2 seconds on the 1/4. looks like I was being totally honest buddy. WTF?

Now, here's the killer. That's for THAT CAR. Back in the day when S54's made 1kw more, I think some still do. And the mid-range was largely the same.

So yeah, for a car with moderate mdrange maybe a tenth or 2. Which is what I posted. Not for Ary's car. PLease explain the dishonesty.

And 50/50, yes I am Hawk. Call all the ou's on speed-dial & tune them. Quick, you wasting time.

 

[BonedM3]

This is not about me; I didn’t mention anything about my driving skills or my times. Don’t try and make this about me.
You mentioned that the regulars were 0.3, 0.4 down and we all know how difficult it is to run a good time at tarlton especially at night.

So 13.6 is definitely a great time for an E46 M3, nothing taken away from Ary. Ugs ran 13.5 and he normally runs 13.0
I was advised many times to put a 4.1 diff in my X E46 as this would off brought my 400m
down by at least 0.3 or 0.4. You were one of my advisors.

You use to love to race at tarlton, why did you fit the 4.10 diff? Too bring your times down.
Cut a long story short, I believe that the 4.1 diff will help to run better times.

So you should have posted the full story......Peace out

 

[SoulBladeZA]

4.1 didn't help me much at Tarlton, then again I still have a mediocum of mechanical sympathy.

I ran the same times at higher exit speeds (late 13s, mid 160s) with the diff.

PS 50/50 what happened ekse, thought you were Sherwin's bra?
