The only chance you have for a decent gain is forced induction. Good luck. I hope it works out for you.

Significant traction issues in first gear with a supercharger. Need R888r tires aired down to 22psi to have a chance at hooking up on a warm dry road. Wet? Cold? Don't even bother.

I 100 percent agree. I wouldn't go the FI route but if you're looking to roll race or whatever it is kids these day like to do then it's the best bang for the buck. E92's are great jack of all trades cars that can be really track capable but they'll never make good high horsepower cars, in my opinion.

Totally agree. I personally think the e9X M3 is the best car for the money right now by far.

But it's no stop light drag car. Kudos to someone who wants to try tho. I bet with a supercharger and R888r tires aired down, it could do low 3's. Best I did was mid 3's with Pilot Super Sports at regular tire pressure (mid 30's) without launch control on my former e92 just stabbing the throttle off idle and short shifting at 6k rpm in first gear.

I'm sure someone could find a way to bolt some drag radials on it and get a decent 60 foot time in an M3. But then again, why? You're taking a multi dimensional car and making it one dimensional and still not very good at what it does.

If I remember correctly, there was a member years ago that slapped on DRs to his ESS 650 and did a 10.65 at 130+ on the East Coast and his 0-60 was 2.9 seconds. That couldnt happen on the street tho. Without heat and VHT the DRs would spin. So R888r's are really the only street option.

That's definitely moving but I'd be more impressed with an E92 M3 than can run a 1:35 at Laguna and then make the drive to the grocery store for a six pack without changing anything. Haha. To each their own though.

M3 is a track car.
M3 is not a drag car.
M3 is loser at red light racing.
M3 asks to be sold to enthusiast.
M3 says buy Camaro.

I'm with you...but we're lucky with race tracks and canyons within driving distance. There are a lot of people that aren't so lucky just lots of straight roads so I guess maybe that's the only option for some.

I don't know what a "force on the street" is, aside from guessing that is drag racing. If it's drag racing that's not my area of knowledge, but I'd say just sell the car and buy something FI like many other said.

If it's fun on the street - my 2c are to do this:
- Leave the suspension alone. Stock suspension is amazing on bumpy roads and very comfortable. If it's worn, just replace with stock parts from FCP Euro, or something like Ohlins R&T. No springs-only mods. No crappy standard Koni yellow dampers (been through that on E46 M3 - they're crap)
- HFC resonated x-pipe and straight pipe muffler or valvetronic muffler. E92 M3 V8 sounds are amazing and make it much more fun
- Don't drag race - newer FI cars will win in a straight line
- Don't do low hanging front lips, don't do big spoilers or wings. Just have fun with the car - capable and fun on its own. Driveability on the street is valuable

Based on what you want...Supercharge. The End.

Couldn't agree more for a street car!

This thread has been entertaining. I envision a car with a modest power bump including a loud exhaust, fancy wheels, front spoiler lip thingy, and rear wing.

It's been three pages and no one has said it yet so have this.... LS swap it!! My favorite part of the vid is when he said his ESS Supercharged s65 powered m3 was "absolutely gutless" https://www.lsxmag.com/news/feast-yo...wapped-bmw-m3/

So far from some discussions I've had with others and this thread, I think the starting point is HFC xpipe and a tune to go with it, similar to what you stated above. I will look into the tunes you noted. Is something like the MS Stage 2 intake worth it? Karbonius is awesome, but a little out of my plans.

Also with the M2, you aren't wrong, but my idea is to get that one in 6MT and I like the smaller body compared to the F8X. I think the 6MT should add back some of the character lost on the newer body style, and balance out the DCT E92 very well.

Stock is around 340-350. With a catless or HFC aftermarket xpipe that has the X in the right place, plus an intake and tune and 93 octane you get to ~375whp
So 375whp = $1200 xpipe+$400 intake+900 tune = 2500

To get to ~410whp it'll cost:
282 cams 2.5k + headers 2.5k + header xpipe 1.2k + tune 0.9k + karbonius 2.7k = 9.8k

To get 420-430whp it'll cost:
292 cams 3.5k + all the other stuff = 10.8k

Or you just buy this for 7.5k and be at 550-600whp
https://esstuning.com/s65-g1-interco...harger-system/
Given your opening post and thread title I strongly suggest you do the supercharger. Getting NA whp out of a 4.0L NA engine is almost impossible.

There are plenty of good intakes that are reasonably priced, MS II, AFE, Dinan, etc.

What do you mean by an x pipe that has the x in the right place? Do you mean one where the X is pushed further up? Also I saw that you recommend ESS/Epic/RK but how about BPM?

Also, don't mean to thread jack but how do you like your E92 compared to the CS? I'm sure you've written about it somewhere but can't seem to find it.

I meant the x as forward as possible

i've posted the comparison a few different times. For the street, 100% the e92. There is no comparison at all. For mountain roads, again the e92.
The CS shines on the track, where it's huge speed differential serves for something.

Does having the X as forward as possible yield more power compared to it in the stock location? So something like an ESS X-Pipe or Bimmerworld would provide more hp over a challenge x pipe or Active Autowerke?

Yes.

Someone posted up dyno results once, they were pretty clear. It isn't a huge difference in a NA 4.0, but it is a difference

Epoustouflant · 07-25-2020, 02:35 PM

A catless tuned DCT M3 is still quick, I find some of the answers here surprising - Cali and Texas are worlds of their own from experience.

460PS is still quick when kept on boil with the DCT.

That M3 will be ahead of the usual modern suspects; Golf R stage 2, tuned N54/55s, stock Coyotes, SRTs, stock RS3, tuned S4/S5s, 987, 981, 997 & 991 non GT/Turbos.

You'll get stomped by current gen tuned S55s & AMGs no doubt, but we didn't get those for a reason 🤷🏿

Syt_shadow,

Did you notice a lot of low end torque loss with aftermarket headers and 282 cams? I would expect it would definitely be noticeable with 292 cams.

No, but remember the 284 cams were on a stock engine and the 292s are on a 4.6L.
The dyno plot of the stroker with 292s is in the stroker thread, it makes tons of power everywhere.

What remains to be discovered is whether a 292 cam on a 4.0L will lose lots of low end power, and how much top end it generates. Fortunately a set of 292s is on its way from Germany...

In the E46 world people were able to have their cake and eat it. That's the beauty of vanos. I expect the same results in the E9X world

There's no torque down low and we don't need it anyways, so I say f it give us more top end please!

nycplumber · 07-27-2020, 02:08 PM

292 cams will make you lose power up top on a 4.0. I have dynos to confirm this

SYT_Shadow and I had been discussing this set up. Care to share the dynos?

pbonsalb · 07-27-2020, 04:44 PM

Not the result I would expect. Who did the tune?

nycplumber · 07-27-2020, 07:37 PM

I don't know how to share images but if someone wants me to send them I will. Epic did the tune

pbonsalb · 07-27-2020, 08:48 PM

Epic tried to tune for 292 cams and lost top end power or you ran an Epic tune for stock cams and then changed to 292 and lost power?

Car was tuned for 292 cams specifically. Full race set up, race gas ect
