S54 Dyno Database

I second the above motion!

I'll have to dig out the video, however I had mine an a mainline dyno back in mid-2015 iirc. Was stock except the exhaust. Full system, euro headers (car is euro spec), no cats, section 2 three inch status gruppe x pipe, megan muffler. No tune.

Made ~265whp iirc.

For reference, I also ran the 1/4 mile around the same time; 13.37 @ 169kp/h (105mp/h)

Found the dyno graphs yesterday while cleaning out the glovebox!

Here's mine this week after installing my TMS Airbox and having Hassan tune it. I am very, very pleased with the results!

334whp, 252whtq on CA91 pisswater

• Turner box
• HTE custom dyno tune
• Kassel CSL spec HP DME
• Kassel MAP
• Turner underdrive pullies
• SGT ceramic coated headers
• Euro Sec1
• Stock Sec2 / 3

Nice results, thanx for adding to the data base!

On the face of it, yeah! I kind of expected a slightly bigger delta but perhaps I've found the next restriction.

The general consensus with euro tuners is that US (W)HP = euro BHP, we don't tend to use WHP figures.

So in comparison, a stock euro E46 M3 generally makes 315-330 BHP over here, a healthy car with an airbox and supporting mods generally makes 340-360 BHP etc

Can't wait to see what the restriction is

👍 Out of curiosity, since your oil sample is pretty consistent. have you tried amsoil?

I have not, I ran LM when I first got the car, and those samples didn't look as great.

Interesting comparison Crooked. So do you mean you each sample has 2 weekends of trackdays in it? I'm no chemist, but is increased molybdenum ( I assume is molybdenum disulphide) & zinc ( I also assum zddp) means increased wear protection with the redline? The consistency definitely looks good. I was just following the 300v recommendations which they say isn't designed for long change intervals. They recommended every track/race event or 3000 miles. I think your car is a track car towed to the track right?

Yes, the car doesn't see any street use. Correct, each sample is two weekends of track miles. I'm staying with the 300V because of the lower lead wear vs the Redline.

Yea, I pulled my oil filter cap out of curiosity to see 10w60 LM cold and it was really thick. I'm on redline 5w50 now from LM 10w60, which has lower viscosity at 40C and very close in viscosity at 100C with higher VI. I tried the 300v before and liked it but they don't recommend it on street cars and advise to change the oil after a track day. That would get pretty expensive since I try to drive the car a couple of times a week in the canyons and such.

I run it for two weekends, roughly 6 track days - Left 3 samples are Motul 300V 15w50, right 3 are Redline 50wt race.

Cool Experiment BBR, you ever think of trying 5w50?

Yes, that would seemingly be ideal, but Motul doesn't offer 5w50 in 300V, only in the Sport line. I still might go that way eventually.

Interestingly, though, the Motul 300v 15w50 Competition has a 40C viscosity value of 122 mm/s where the LiquiMoly 10w60 is a whopping 168 mm/s, making the LM much thicker for California "cold" starts, despite having a lower Winter rating.. Wish I had done more research on this years ago.

Dynotech which is Dyno Dynamics budget range I think.

[Tones]

Rebuilt S54 with the usual fixes in an e36 M3
Karbonius Airbox
Full Supersprint exhaust with ceramic coated stepped headers (no cats, resonators in mid pipes, race muffler)
Stock ECU with GreshM patch harness and HTE Performance Alpha N tune.
Bimmerworld twin fuel pump kit and rebuilt stock injectors
Australian 98ron fuel

Car made 295whp on a dyno where standard e46 M3s make around 250whp.
Green run is with a canned Alpha N tune, Red is HTE dyno tune.

What dyno is it that reads whp so much lower than others?

^^^Nice results, looks like some solid gains down low and up top.
