Zeemax Dyno Predictions

[Sherwin@xcede]

Ok so now for the 1st time we have had a car on this dyno. I have no idea how this dyno reads, or any other Cape Town dyno for that matter.

But I do have extensive airflow logs for the E46 M3 we had there, which had no hardware and pump fuel. So I can now draw meaningful conclusions on what other cars should make there, as I have plenty logs on my laptop.

There might be a small margin for error due to the size of the rollers the dyno has, etc. But this is just a flyer.

If our chipped but otherwise stock E46 M3 makes almost 240kw there, then a modded E46 M3 like Radz car will make around 275-280kw there. I know this from checking the airflow difference betwen the CT car and Radz car.

A stock E9X M3, will probably make between 280-290kw there. One that is properly chipped with the catts removed will make 310-320kw there on pump fuel. Please note, I am saying properly chipped ones. If there has been a chipped one there, that doesn't mean all chipped ones will make the same. I can assure you some will make more.

A stock 335, well it's hard to say, probably between 230-250kw. A full house one, maybe 290-300kw on racefuel.

What you guys think, am I on the money. Please don't turn this into an 335 vs M3 thread, this is just to see if I understand the dyno and if my predictions are correct.

A stock 35 makes about 205-215kw at zeemax, from what i recall.
And we have gone up to 325kw after mods.

May i ask why you are trying to predict what a car should do on this dyno.. Rather just get the car on it and get actual readings?

We did, we got a chip only E46 on pump to almost 240kw. And also, because when a car does go on, I will look back on this thread and see if I was right. Just because I can. We actually may have a V8 on there next week, but the guy is telling us he prefers KSD's dyno. Dunno' what that means.

Anyway, here's a prediction. During the course of this year we wil get an M3 with bolt-ons to 320kw on this dyno. Let's see if I'm right or wrong.

 

[Rennzport]

kp it on this dyno, since most ct guys have run on it.. So good for comparison.
Getting over 100kw and 200nm gains on the same 35 on the same dyno was pretty good imo.
There were some leaks tho, and we will re-run.

There was an m3 v8 that ran about 290 or 300, and apparently it was chipped.. No need 4 us to mention the tune though.

---

What exactly do u mean by all the bolt ons to get to 320kw.. I think its better to predict the power increase u hope to achieve from the stock run, coz it may just (by chance) run 310, meaning a 10kw gain to get to 320kw isnt anything to write home about.

Yeah, we gonna' try.

Wow, that's spectacular gains. Well done. 200NM GAIN! WTF? The owner must have been smiling!

Yeah I saw Twinz in another post mention X-File racing or something. doesn't matter. I rate 320-330kw is possible with the right hardware and tuning. And with 330kw all the way to 8800rpm, it will have an irresitable powerband for top-end runs.

Have you had a V10 M5 or M6 on that dyno?

 

[Rennzport]

there was an m6 yes. Dnt know the numbers.

Yeh, the 35 is a torque beast. No doubt about it.
Thats what makes it fun to drive, as u know.

So you are looking at approx. 30kw gains on the v8?
Software, pulleys, xpipe with hfc, xhaust?

Yeah, the bolt-ons are chip and custom X-pipe mostly. These are the intial gains we were getting. Around 35kw with just chip and changing this section:

Now we have designed an X-pipe which works for us and fine-tuned the map after doing like 40 cars, we end up with these gains:

Which is why I say, if the car comes into Zeemax stock making around 280, we can get it up to around 330-340.

But hey, the proof is in the pudding. We've proven it everywhere else. Let's do it in CT.

 

[Rennzport]

just dyno it when the south easter is blowing

Would like to see the v8 when done.
Should be interesting.

what torque gains are you looking at? The m is missing some.

 

[Sherwin@xcede]

Here's some dyno's back to back, from Jhb.

Stock Coupe:

Chip + zorst sedan:

Back-to-back on the same day.

BTW, M3 has more than enough torque to the ground as it has a 3.84 final drive.

Torque to the tarmac = torque at the wheels X gear ratio X final drive ratio

But anyway, it's horsepower that wins races. That will start a big debate so let's drop it, unless everyone is bored.

 

[Rennzport]

no nd 4 debates at this hour.. But i am bored

Besides, all the talk is just pointless about hp and torque if nobody is actually gonna put the cars on the "road" to test what wins.

And dyno numbers just make for good reading
Its what sells the products.

Yeah you right. Nobody loves a dyno queen. Need to put it on the road and line-up. Or even better, take it to the track and run a low 12. But the year is young. I get a feeling it will be a good year for all tuners and everyone will improve.

I personally think George Smooth's car may well break the record this year. His 335 is crazy fast and he is an old school peddler. George, let's take it down to sea-level and run a time?

 

[George Smooth]

I wont get a visa for coast but I am working on getting a drivers lisence so will be at a prepared track day soon. Don't know about a record but will try. I managed to get a DCT rear end so am swopping the manual out as last time out I spun in third.

Say you asking about a prediction when your CT agent has already posted the result here : http://www.bmwfanatics.co.za/showthread.php?tid=4808

would definitely like to see george down here

Btw, whats the smooth best time?
Does he hold the record up there?

TORQUE MULTIPLICATION FTL! C'mon bribe the vrou with some new shoes or a Gucci handbag and let's hit it down to Margate!

No ese that was an E46, I wanna' predict what the V8's will end on. Or maybe even the V10's.

 

[Rennzport]

the prediction is for the v8

George has the Tarlton record at 13.0. K has the ODI record at 12.9. Although, if truth be told, ODI does have much better traction compared to a night-time Tarlton. And ODI is a bit lower. So, in general, the times are slightly better mostly due to the traction.

y dnt u guys make a trip to ct.. U have already run at durbz.
Lets see what happens where the oceans meet?

Its only a few hours away

Haha driving to Cape Town for me is like taking a trip to the moon. Got to plan a year ahead at least. I went to a bachelors for four days in January. What a disaster.

X, little OT but here goes. From what i understand the US guys don't have Brake Energy Regeneration

But we do right?

heres a quote from the release notes...

"Intelligent energy management featuring Brake Energy Regeneration likewise
serves to further enhance the efficiency of the V8 power unit in the
new BMW M3. In this case the power required for the on-board network is
generated specifically during overrun and during application of the brakes,
serving to charge the car’s battery at exactly the right time without taking up
any of the energy contained in the car’s fuel. As long as the engine is “pulling”
the car, therefore, the alternator generally remains disengaged. Apart from
particularly efficient generation of electric power, this also serves to provide
more drive power and traction for supreme acceleration at all times"

With regards to the pulley upgrade...
EDIT. Now the pulleys power the A/C compressor, power steering pump, water pump and alternator. If changing the alternators pulley, wont this effect how the BER system works? Perhaps showing some gains but screwing with effecieny

4 day bachelors.. No wonder u need to lodge an application for a visa. lol.
Convince the wife its 4 a nice holiday, especially 4 her
