Mod potential of the E92 ///M3?

[MisterBMW]

I been reading all those procede-335 posts on E90post.com and I was wondering whether the new M3 will have similar potential for performance upgrades. I know I know, its an NA V8, not a twin-turbo. We all love the M3 and we are not buying to mod this piece of fine engineering product.

So as far as performance mods goes, not much I guess?

No really much you can do unless you supercharge it. Sorry.

You can be sure BMW will come out with a CSL version is a couple years with 50 more horespower. Tuners will have the usual software tweaks for 20 hp or so. Supercharging will be the best bet for more power, but that is limited as well. Turbos are fare easier to extract more horsepower from. I think I can be satisfied with an 8.5 lb/hp car compared to my current M3's 10.25. Suspension, wheels and aesthetics are what I expect to do.

Well if you want better performance i suggest the following, noting that these suggestions improve that but do detract from the whole luxury part of the car.

1.Remove all the seats & replace the front drivers one with a racing seat (Like what Hartge did with the H50 and a GT3 racing seat). Taking care to remove anything else not deemed necessary such as the centre console arm rest, a/c, radio and so on.
2. Install roll cage
3. Race set-up suspension
(4. You could probably even get an aftermarket carbon fibre bonnet, that'd look pretty cool.)
Then just get it on the track!
And there you have it.

DIY E92 M3 CSL.

Well you can't put in a cheap and easy mod like Procede to extract 50+hp but I will add:

1. CF Strut brace
2. Gruppe M air filter
3. Aftermarket sport cat + exhaust
4. 4-6pot front calipers + stainless hose
5. suspension? but depends on how good or bad the stock setup is

This should be able to spice up the car....

I think there will be a lot of performance mods available from companies:

Headers
Exhaust Systems
Straight Pipes (Resonators)
Cold Air Intake Systems
Softwares
LTW Pulley Kits
Camshafts
Force Induction


That'll get you some good extra power...how much power do you all predict with just bolt of performance parts (Exhaust, Intake, Pulleys)?

[EBuyuk]

I am guessing:

Headers 35hp
Exhaust Systems 2-5hp
Straight Pipes (Resonators) 0hp
Cold Air Intake Systems 17-20hp
Softwares 15-20hp
LTW Pulley Kits 15hp


However, I am sure that they will come out with a limited slip differential. I am not sure what gear ratio the M3 comes with but in my E60 M5 the ratio was 3.62 and I put the 3.91 diff. from Dinan and there was a 8% torque increase and it made a huge difference. You felt like the car had just recieved another 40-50hp.

Sorry, but your expectations are far too lofty.

i am gonna guess no....which header add 35hp.... CAI 17-20hp?
are these wheel hp?...wtf

If it's setup from the factory like the E46 M3 then there will be mods but the gains from them will be minimal without spending alot of $$$.

Huh? What kind of BS is that? There will be plenty you can do. As much as the E46 M3 and more.

These guesses are not to the wheel, they are to the engine. I came up with these numbers as they are a tad lower than what you got for the E60 M5 with these parts. I am guessing these numbers because the new V8 is derived from the V10 in the M5.(or at least the same design concept) If you got supersprint or evosport headers for the E60 M5 you get about 40-45hp to the engine not wheels. Therefore I do not think that my numbers are lofty. Now another thing to consider is that if you add all the hp together, that is not what you are going to get with all those parts installed. For example, the pulley for the M5 is suppposed to give 20-25hp on a stock car, however if you add the pullies to a car with headers, camshafts, ecu, differential, you only got about 1hp. Also there is a cold air intake coming from K&N that has been dynoed and it will give about 25hp to the wheels for the E60 M5.

I was trying to say that the feeling you get when driving the car with the new differential is as if adding about 40hp. But you do NOT get any hp in reality just a torque increase throughout the rpm range.

One of the moderators over on m3forum.com seems to believe simple ECU tune could net somewhere around 50 hp because he thinks BMW has purposely de-tuned the car in its current state. He seems to know what he's talking about and it was an interesting theory.

IMHO i really doubt it. They had said that about the E60 M5 before it came out as well but it turned out not to be true.

It's only a theory, but he had quite a few good points to explain it better than I did. I would look for the thread, but I'm too lazy.

Intake, exhaust and pullies (headers are too loud for me). Grand total of 20 crank hp probably. Some lightweight 19's, BBK, sway bars and coilovers. That is the most I would do to it. 3500lb car with 440 hp, nice brakes and a great suspension. That is probably as quick as a 996 turbo.

The headers that are on the S65 are already state of the art thin-wall equal-length hydroformed. Unless we get a dumbed down American setup for emissions, I don't think aftermarket headers are going to either be louder or give any horsepower.

Modding the E92 M3 will be no different than modding any other NA straight six BMW has sold. Finding big HP gains from bolt on performance prducts wont be easy unless you go FI.

The 335i will be the "Tuners" choice of BMW...hands down (This is a shift from previous gens where the "Tuners" focus was mostly on the M3). I dont even think this can be argued. It is a much better platform for finding big power for not very much money.

However, I will still be putting my money down on an M3. Hopefully

I know the discussion thus far has been on what you can do simply and without FI. But if you do want to go that route the options for the new M3 will be SICK.

How about 550 hp / 420 ft lb?
Someone already has obtained this with a supercharged RS4 at moderate boost. Sure I rounded up just a bit, but like I said only moderate boost.

How about 600 ft lb in a BMW V8?
How about 700+ hp in a BMW V8?

Have a look here. Just learned about these guys but they look quite capable and professional.

To those people who think they can get 60-80 hp without FI and without sacrificing reliability: what are you smoking/dreaming? This will be a $60k+ car, which has a brand image to protect and plenty of other high performance cars to compete against and all. What makes you think BMW will release it with that kind of untapped potential? If they could have designed the headers to provide the additional 30 hp, they would have. This is not some Honda Civic you bolt parts onto (with the exception of FI) and see a drastic difference. Somebody even mentioned software. Give me a break. So, you're telling me someone else can write better software for this car then the highly trained engineers who designed the car in the first place and know the engine parameters inside out? Again, that kind of tweak works with lower end cars that are tuned down due to fuel economy, emissions, and noise concerns. Except for the emissions criteria, I doubt that BMW is too concerned with the rest in the M3. And if you want to go screw with you emissions, that's another story (then you can even remove the converter or something stupid like that). If you really want to mess with an engine and see results, try the 335i. You can play with the turbos, but rest assured that your engine will most likely not last as long as it was designed to last if you do so.
