lining them up doesn't compare engines, it compares engines, gearing and weight.

Vehicle is a 2002 325Ci.

Dyno'd around 4 years ago bone stock with only a K&N panel filter @ 161whp on a mustang dyno (i think).


Current performance mods are a custom after axle Y-pipe into a 3" Vibrant muffler, K&N Typhoon intake, UUC pulleys, Besian Systems Vanos Seals, 3.46 auto diff swap, and regular maintenance. The car currently has 112k miles. It managed to put down 165whp.

My question is this, what does a stock E46 M3 make (average) for WHP and WTQ on a Dynojet when the CF is set to SAE?


EDIT: Read the entire thread, I have my answer.

My Ride: M3
I just saw this thread.

E46 M3
3500 cc stroker
Twin Turbo
Nitrous
9200 rpm limiter

990 whp dyno Dynamics in shoot out mode (= zero correctio)
This equals to 1180 whp dyno jet.

Holding the fastest 60-130 mph WORLD RECORD for E46 M3



This is my E46 M3 TT.

I work on a E46 Sedan X Drive. Put another 3500 cc S54 stroked engine into E46 Sedan X Drive. Twin Turbo....

Goal is to make over 1300 whp and go 60-130 mph in less than 3 seconds

Link to my XM3 Twin Turbo

I was going to ask you some questions, but i see you deleted everything out of your own thread; the thread you have a link too.

So i don't care, i have no questions now.

Well I finally got the car to a dyno, and have something to share of my own...

M54B30 ZHP
E36 S52 headers to a hacked up dowpipe/merge, to 3" high-flow cat and 3" exhaust
AFe intake
AA Tune (before the headers, I did this dyno to help inform an update)
Rogue pulleys
DynoJet dyno

217hp/206tq



We'll see if this changes much after AA adjusts the tune for the new headers.

Murphy, something is just not right with that dyno - the low end is VERY soft. I would have active take a strong look at the Vanos curves, the A/F ratio is spot on however.
For comparison, see page 1 of this thread.


(it may be that it just isn't the tune, it could be the exhaust side - a bad merger could cut exhaust velocity and cause a drop at low end, or the headers themselves might not be ideal?)

Yeah, the headers themselves are pretty craptastic, due to needing to comply with SCCA ST category rules. The E36 OBD2 headers I'm using have a 2" output, bolted to a 2.25" tube, using a crappy merge to a 3" cat.

Here is a picture of the headers:


And a picture of the downpipe, bolted to the shorty headers that I couldn't use:


And a picture of the merge/cat:


So you can see, this is far from ideal. I'm hoping at this point that this is at least better than the stock headers once the tune is updated!

It probably will be...but I would have personally done the CAT a bit past the merger as opposed to the middle of it. Otherwise, it doesn't look bad. if your tune works, it would put you within range of similarly modded cars are putting down - and be emissions compliant.
