    • 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.

        Yeaaa they are heavy...
        I am looking into a set of 18" wheels now.. Thanks though.
        Whos a good tuner for the s65.. Evolve??

        Nice to see you here, welcome - and glad you joined. When you get the time, would you mind giving a small write-up in regard to your car? I am interested in your thoughts on the stroker - both good or bad. Does it lose any of the "M" feel when stroked, or is it basically just more torque across the band? Just curious about the car in general - videos are good too. Not too many owners of these cars that I know. Click here to enlarge

        Cheers.

        Thanks for the info to clarify the run and welcome over... Nice ride bro

        Yes, @evolve & @Imranevolve will def be able to wake that S65 stroker up & get it running to its potential. Lots of lightweight 19s you can go with, wrapped with R888s or MTs & you'll be shattering that old record (both the ET & Trap Speed)

        Cheers.
        I love the power from the stroker kit. It has great mid range power and feels exactly like the stock s65 but with more tq down low and pulls hard to the rev limit. It really is a BLAST to drive, spins 2nd pretty hard and feels like a slingshot Click here to enlarge
        Yea not many people keep them NA, they usually boost them. I personally love the all motor power over the turbo on a stick... Its very linear and that helps with wheel spin...

        Cant say the same for a VR6 though Click here to enlarge

        Nice thanks for the info! Ill get in touch with them and see what we can do.
        Yea it would be nice to have it hook in 2nd. Hopyfully ill get a rematch after the tune..

        You have a lot of choose from.

        Evolve, OE Tuning, Gintani, Active Autowerke, etc. Where are you located?

        You don't have to go all the way to 18 but up to you.

        You should look into the Schrick cams as well.

        It's going to improve on all the M characteristics. The only thing not accounted for is the shift in the powerband. So it will lose some of that rush to redline as the peak HP and torque move to the left but that can be remedied.

        The Dinan Stroker recycles the OEM cams? Or just recommending something more aggressive?

        I have been but the problem is that nobody has installed them.. or atleast that i know of.... I can imagine the cams will help the stroker on the upper rev range...

        Yes, big difference. You really should look into it and they have been installed. VAC has done it.

        I dont really know the owner of the C5Z. Just met him that night...

        No worries bro, glad you posted up it confirms and/or adjusts a bunch of info. No offense but the cost of that motor with a stoker for stock cams is just crazy. Has anyone seen results for the Schricks, as I recall with my VR6 I used their 276 cams and only netted 12whp. Granted its a totally different motor, more so to say from what I have seen on various platforms they do not always deliver as much compared to costs.

        Have you considered using spray on her or a blower with low boost?

        You don't play with M3's and Dinan built motor products if you are on a tight budget. Cost is irrelevant.

        They gain more than that on the S54 and even the old school S14. Completely different motors here with different sets of cams available, there are two sets.

        Did you dyno your car btw? Where are you located?

        Really, so whats more HP equate at the wheels 20hp, 30hp? As for cost Dinan didnt use the cams for a reason most likely the ability to pass emissions and perhaps lack of power overall. I'd be interested in dyno's of cammed stock motor M's to see this cost no object power increase.

        We don't know what the HP is with the Dinan stroker it would have to be done. I can't speculate, I'd venture to guess it would be healthy.

        Dinan doesn't do cams because for one they were not available when this kit was designed and for two it would increase the cost both in hardware and in tuning. Same reason for RDsport.

        You can look at Schrick cam results on other M motors if you like.
