e46 M3 dynoed before AA install - South Africa

[Matt Q]

Hi there

Just thought I'd do a nice before and after

Here is a dyno run we pulled today, very happy with how the car is performing in it's (almost) standard guise. I think this is a fairly tight pull for an NA M3

Should be getting my AA stage 2 gen 3 kit soon and will post some new figure then

M@!

I'd like to know what this freaky dyno is. It reads even higher than the US dynos. There is no way a stock N/A M3 is making that power.

[jtrejo]

330hp? is this at the crank or whp? if its whp what are your mods?

[techlogik]

Us Americans have no idea how nm converts to whp..too lazy to google it.

It shows the drive train drag on the bottom of the graph so its corrected for flywheel.

[Heiss M3]

^^^ You guys do know that these aren't HP numbers right...:rofl:

From the looks of it i'd say you guys knew exactly what was going on :eek:

[Matt Q]

Ok first off this is metric so it reads KW and NM of torque, converted here for those who don't have converters on their mac's dashboard

246.3kw = 330.29 HP
360Nm = 265.52 Ft Lb

2nd off it's corrected for flywheel

3rd off we run 95 Octane as standard

4th off my car has the following mods:

Turner induction kit with K&N filter
Software upgrade
Turner pulley kit

So that said these mods shouldn't have made any HUGE HP differences.. only allowed the car to breathe and run a little better.. the dyno figures here are what the car should be pulling out of the factory... 330HP.... however this car is a 2001 and has 85,000km on the clock

I'm VERY happy with these figures as the factory claimed HP on an M3 is off the crank on a benchmarked engine under perfectly ideal conditions... an M will more often than not run around 5% under this.

Also it was about 20C that day.. so the nice cool weather probably helped

M@!

(do you guys also need the KM and Celsius in Miles and Farenheidt?)

Can I ask why the hell you guys use a chassis dyno to guess the engine hp then? Why don't you just let it spit out your whp like everyone else. It's just confusing. The only exception is an engine dyno

[MrBlonde]

Dyno sheets are a joke, but a dyno sheet that doesn't show rwhp?? That's a joke of a joke.

[Matt Q]

Hey different strokes from different folks... this method seems to be the norm in SA - I'm fairly new to this so just went with the measuring method everyone uses here.

I will still post again after the install so a comparison can be made... I can dyno it again for WHP if that's what is generally wanted

M@!

[Jean@ActiveAutowerke]

Nice numbers. The car looks strong.

The software he used for his sheet measures the wheel hp and adds the drag graph at the bottom to it. The RWHP is actually a click away, the drag is relatively high for his car but a good dyno operator can pick up quite a few things with that measurement. I.E. If the drag is higher than the norm for that model tire pressure might be low, oil might be too cold etc. I'm not a big fan of it neither but I think your statement is rather harsh.

Thanks for the feedback... and a very interesting point.... we JUST added oil before the dyno as the level was a bit low.. the oil was probably in there for around 7 minutes before we wacked it.. I guess the greater viscosity could have given a higher drag reading.... hmm interesting

Hi Again...

here is a vid of the car after fitment of the Horsepower freak titanium exhaust and clutch... after a bit of bedding in that clutch is biting like a rotweiler and the titanium is louder than....er... well.. see for yourself

[Matt Q]

No one want to watch the video ??

BTW - Power is pretty much unchanged by the addition of the HPF freeflow exhaust although my bottom end torque and KW was less.. it maxed out at the same.

I recon this exhaust will really come into its own in a FI environment

M@!

[freerider]

I watched it M@ :)

[Matt Q]

I've deleted the previous vid - here's the new one with a better ending.. ok - it feels finished now :)

doesnt matter what your number is, as long as you go back to the same place for dyno see the gain after the supercharger, thats the most important, and IMO, what the dyno is best for.

THANK YOU - Finally someone who shares our opinions on Dyno's - There are so many variables that really I couldn't agree more.. this is the best route to go with a dyno IMO as it gives you % change before and after which is what you really want.. they power is always gonna be an estimate as no 2 dyno;s are exactly the same

A dyno day also works as several cars are compared on the same dyno.. however comparing different cars on different dynos on DIFFERENT DAYS just isn't every going to be a perfectly accurate comparison

I am sure the weight saving will make a difference in performance. Cool vid and bloody load. I noticed the dyno uses very small rollers. Is it using hyperpower software?

[Matt Q]

Dunno much about the dyno

Interestingly enough... although the dyno doesn't show much change... the car is DEFINITELY responding better once under heavy load... going from 12km/h - 200 km/h shows a marked difference in feel - the engine just doesn't seem to be working as hard

[Matt Q]

er....edit 120km/h - 200km/h

duh!!
