• Watch a Dinan 4.6 liter stroker S65 V8 E92 M3 get smacked around by a cammed C5 Z06

      To get a lot more power of the E92 M3 in NA form beyond bolt ons increasing the displacement is really the way to go. An extra 600cc's is a nice chunk to pick up made possible by the relatively short stroke in stock form providing quite a bit of room to grow. However, the LS6 V8 under the hood of the C5 Z06 is sill larger at 5.7 liters. With an aggressive cam only the Z06 can put out in the 420 wheel range and with exhaust and intake 450 wheel is within reason.


      The S65 V8 at 4.6 liters is capable of 441 wheel horsepower. So, on paper, this actually makes for a fairly good race especially with a DCT M3. Yes, the C5 Z06 has a weight advantage but the M3's higher redline makes for a gearing advantage. So what is the problem? The 20 inch Hartge wheels the owner chose to put on his car which are basically boat anchors sapping power. The Hartge badge on the trunk clearly not making it up for it.

      Furthermore, the 441 wheel number for a stroker M3 came from an RDsport setup, not Dinan. Dinan uses a fairly mild tune and has yet to demonstrate as high of dyno numbers with their motor. To really take advantage of this setup the M3 owner needs to ditch the wheels, get a new tune, and also look into Schrick cams as the stroker moves the peak of the powerband to the left. Much more horsepower is there to be had by moving the torque curve to the right towards redline with a more aggressive profile similar to how this Z06 gains power with its cam setup.

      Enjoy the race, but seems silly for the M3 owner to spend all that money on the motor only to limit it in other areas.

        No we all get what you're saying. You don't get why it's an idiotic comment. You're obsessed with acceleration performance in roll on racing as a defining characteristic and don't even see why this thinking is a problem.

        Seriously, give it a rest. These comments are ignorant, juvenile, and just plain dumb.

        NO, YOUR INTERPRETATION OF MY COMMENT IS THAT IM OBSESSED WITH RACING. ODDLY, RACING, IN A RACE BRED CAR, I ASSUME IS WRONG.. THER IS NO WAY TO misconstrue the point it does not have enough power.. anything it does well, would be better with more power.. fact

        Seriously, give it a rest. These comments are ignorant, juvenile, and just plain dumb.
        right.. coming from the guy that had to boost his motor.. saying the motor is impressive, but HAS to add boost.. so idiotic, i know

BMW delivered an awesome car, with a $#@!ty motor. comparitivly. does it do everything well? sure, but it would be a feared car if it came with more N/A power. how can you argue that? boosted S65's are crazy.. $#@!ty deal that you have to go aftermarket to get mid 400's and be competitive.. THATS what i said, regardless of which way way a foy retards tryi to twist it.
        I guess my stance is you don't need anymore hp to have fun. Honestly a good driver can have fun all day at the track in a miata. The S65 does everything I could ask at my local track. If not more. Another 20-30hp isn't really going to accomplish anything. M3 really couldn't get any more balanced and high revving motor to me is sublime. Most people could benefit from driver mods (aka driving lessons), than mods on their car.

        I didn't have to do anything. I boosted it for more power. Not to make it better and aspects of the stock S65 ARE better than the boosted motor.

        It's getting tiring repeating this.

        Thats an interesting statement... So if you were happy with the motor and power what led to boost and subsequently a built motor?

        The M3 is complete package car. A car that can used as a daily driver, carry 4-5 passengers, and the owner can take it to road course on the weekends. In that sense, it is a fantastic car.

        I really fail to understand this obsession of making the M3 a freeway racer or drag car. It is not developed from factory for any of that in mind.
        Nobody designs an OEM platform for roll racing... That being said the majority of M3 owners spend their time on the road. Stop light to stop light, merging into traffic and highways are where most spend their time. Thats where their short comings in daily driving show up.

        I get the road course point, thats where the platform is mean to excel. It does very well there indeed, I think @LostMarine is really speaking to his view of the motor. Specifically that if it had more power NA it could be more competitive in all aspects. Its a great chassis with only a good motor so to speak...

        i never said anything about fun. the m3 is fun. i said it would be an ass kicker if it had , or was capable of, more power n/a-basic bolt on.. the miata and s2k are far far better options, and faster.. right? once again, im not talking 20-30 more, it would need 50 more, N/A-bolt-on to have achieved an epic status. but once again, according to sticky, the s2k is a better car/motor, faster, and more impressive..

        BINGO! its so impressive in n/a form, HE HAD TO BOOST it, to get it to be competitive.. but if asked, its plenty capable in N/A form.. but he HAD TO BOOST IT, for it to be competitive.. oddly, im the only one repeating common sense..

        apparantly, this is blaspemy.. as it has won awards.. so there is no need for more power.. even though he needed boost to get into even 4xx hp range..

        I'm very happy with the base the S65 provides. I built my car to promote my websites and also for my own personal enjoyment as a project. It's all unfolding quite well really. The network is really getting going, car about done, coming together perfectly.

        Dodge specifically included forged pistons in the new Viper for the guys that want to turbo.

        A horsepower war accomplishes what? BMW and Mercedes are going back and forth as is. You think Mercedes could not have given the C63 more power out of the gate? You think BMW could not have given the M3 more power either?

        If you need MORE power than that, you can get it.

        You can get in the 4XX range without boost, so what are you talking about? I skipped the 4XX range entirely.

        sets one car ahead of the other..
        BMW and Mercedes are going back and forth as is. You think Mercedes could not have given the C63 more power out of the gate?

        they did, they gave it more than the S65 and comparable to the higher level v8's...
        You think BMW could not have given the M3 more power either?
        they could, just not to the public.. THANK YOU!! thats what ive been saying

        If you need MORE power than that, you can get it.

        right, but not easily from basic bolt-ons, or n/a without doing serious work! They $#@!ed the public into thinking it was a more capable car, because it won "awwards" and a race motor capable of delivering what the public thought they ewould get
