Supersprint full system + Karbonius Airbox + healthy stock motor = YUGE numbers!

Yah you either have a freak motor, or the health is literally stop notch ie. on point with compression, fuel injectors, valve adj etc. If this was dynojet 290whp and above is unicorn territory for a stock car from what we've seen. Mid 270s to mid 280s is quite common. Having said that, your results speak for themselves. You sir have a beautiful example, congratulations. Excited to see what a full SS setup will yield from mine currently.

Thank you! Its funny that you mention mid 270s - 280s; that's exactly what the dyno operators said @ EAS. On average most stock E46 M3s they've tested fall somewhere in between there.

Random aside - - I don't know why people hate the Dove Grey interior so much -- clean, well maintained ones w/ the LSB exterior and super light window tints look good on it in my opinion. Sure it is harder to keep clean and it doesn't age gracefully when not cared for, but overall I think there's a time and place for it.

Dang, that's impressive for the S54. Where do you reckon cams would take you? That motor is pushing 420 crank hp, mighty!

Thanks! Seeing how this is a freakishly strong motor from the factory and responds very well to quality mods, my guess is another 20+ whp? Sadly I'm only limited to 91 octane. With 93 maybe we can bump it up by a few extra ponies.

Thanks! I like your ethos and tastes in mods for this car and you inspire me to do the same with mine. Either stick with tried and true factory parts, or go top-tier aftermarket. Everything else in between seems like a waste of time and effort for this platform. I've been thinking about getting Schrick cams eventually as the cherry on top - - maybe if I ever move out of state in the near future and don't ever have to deal with bullsh!t smog testing every two years, I would definitely consider it.

I was meaning to ask for those of you who have cams - - is it true that it would never pass the OBD II readiness states? One of the other forum members who had cams installed said they could never get one of their emissions monitors set to ready.

All of my monitors show as ready. No smog in PA, but it passes pa plug in obd2.

For you SoCal guys, how are you getting around smog with your airboxes?

Yep swapping back is by far the easiest; it doesn't take that long and you're working from the top with stuff easily accessible. Even if you can find a shop lenient enough to pass you on the visual, most likely the CSL MAP tune will not communicate properly w/ CA emissions computers.

Noice. 62rwhp ~= 71 hp crank (given 291rwhp for 333 crank), so sounds like you're safely in the 400+ club!

Selfishly, nice choice in parts! My exactly setup other than cams.

It's amazing how much power these cars can get from mods these days vs 10 years ago, despite being mostly the same parts. Tuning, though, is a completely different world than it was then.

... going to add cams?

Where do you like to go?

R/T Tuning... not that I think there’s anything uniquely good about them. I went there 12 years ago and have gone there since so I can use the same dyno.

I might go back this spring, as I want to see if one step colder plugs do better. If so, I’ll take a pic of the screen in case they don’t email me the results

Up everywhere vs stock.

Annoyingly they said they’d email me the dynos, but never did. I don’t remember the specific numbers anymore, but they were greater than stock at every RPM.

Aww man that would drive me nuts to not know!

[Obioban]

Awesome, how about torques? Hopefully a healthy gain there too?

352rwhp sae– but on a dynojet that read 276 stock. So, +76rwhp ~= 92 crank hp... so ~424 crank hp.

man I hope not, not ready to buy now . Btw, what are you putting down with your setup?

To anyone feeling inspired, SuperSprint GB going on right now that could, sadly, be the last time this stuff can be purchased: https://nam3forum.com/forums/forum/m...ders#post95255
