IMO, "high-revving" only means easier to modulate throttle/power. |

I don't see why high revving should equal easier to modulate throttle/power? Is the LT1 and LS7 engine in the C6/C7 difficult to modulate throttle/power on??? Or any other engine that has a redline at a lower rpm? High rpm is needed to make sufficient power from a smaller displacement engine, it's not like Ferrari or Porsche chose a 9000rpm redline just so the driver should be able to better modulate the throttle/power... They did it in order to be able to extract the kind of power they do from small displacement engines (relative to the LS7 engine which has less power from 6,2l). Remember that a engines power is made from combustion. To make more power you either need more combustions, or a "larger" combustion. Go large displacement (or turbocharge) and you get that "large" combustion and make more power. If you keep the displacement low, you simply need more combustions to make more power. How can you make more combustions? You have to increase rpm so that you can "squeeze in" more combustions per minute!!! A turbo engine will normally be more difficult to modulate throttle input and power output from (due to turbo lag). That is one of the issues the S55 supposedly has been able to eliminate (more or less). Last edited by Boss330; 12-25-2013 at 03:49 AM.. |

i quoted you and made that comment because you were acting like big V8 motors are not making the power per liter. coming off like European engines are just better or something. really anything that BMW does GM CAN do. (goes both ways). there is no secret to engine building. its simply the style of motor. some like big non stressed V8 motors, some like the high tec motors. i wouldn't say one is better than the other. |

And in my example above with the pickup truck engine lies the "problem" for me with attaching any kind of "mystique" or exoticness to the Chevrolet V8. It's a engine which is not only related to the same engine you find in a pickup truck, but it still keeps that low specific output low rpm character. Don't get me wrong it's a VERY powerful engine and credit to GM for making it! But Ford's SOHC 6,2l V8 for the F150 makes 411hp and 434lb.ft, only 49hp and 26lb.ft down on the 460/460 numbers of the 6,2l LT1 engine in the C7. So Ford makes a short stroke, SOHC 6,2l V8 that has nearly the same power as the C7 engine, only it's for a pickup truck... That 6,2l pickup engine would be a 464hp engine in a 7l configuration, only 41hp down on the LS7 engine. And that would still be a engine in a pickup state of tune (it would only need an additional 6hp/l to be at a LS7 power level)... To me that puts a perspective on the LT1 and LS7 engines degree of development over a competitors pickup engine... And probably also shows the benefits of Ford's more modern engine architecture with SOHC and DOHC engines. And instead of just putting that big 6,2l V8 in the Mustang they make a 444hp@7400rpm 5l DOHC V8, which is only 16hp down on the 6,2l LT1 engine in the C7. Probably once more showing that Ford has a engine architecture that allows them to play around with different ways of achieving power, they don't have to go large displacement. So as you can see, I'm a big fan of the Ford V8 engines Not so much the old school GM engines... Last edited by Boss330; 12-25-2013 at 07:54 AM.. |

Very interesting and surprising about the German magazines, hats off to those folks for being very open minded. Mystique indeed!

One can easily get to the 460 hp range with simple bolt ons and software in the S65. I think some have dynoed at 400 rwhp (probably with 15% correction). That can get to 800 crank hp with FI. There has been some demonstrations of quite impressive reliability at those power levels. What can a Z06 get to with simple bolt ons and software, I have no idea as I don't follow that "scene"? I'm sure they can get to 1000 hp with turbo charging.

a LS engine. you can do full exhaust, intake, heads and a cam all done at a much cheaper price. also you can even work on the car your self. with the mods i listed you can gain 100WHP over stock without doing any FI mods. all n/a and will cost under 10 grand. you also could do a stroker kit for the z06 my whole thing was about N/A, i wasn't talking about FI.

Like you just had some comments on how you didn't like the direction BMW had taken with "everyone" talking about the tuneability of their new engines? Now the lack of tuneability is a problem with the S65 and a bonus with the LT1/LS7 |

If I understand you correctly it's ok (in fact even great) for other brands to be tuneable, but it's not for BMW In Europe the Tuning industri started with brands like BMW... I remember Alpina versions of 3 and 5 series in the early '80ies being some of the cars we most wanted. And Alpina did some great turbo versions of BMW's I6 engine. Even before the factory 7-series with turbo engines in the '80ies. |

there in fact is a thread started right now that both of us posted on. the OP is disappoint if there is no room left on the table to be gained with a tune. whats funny is that every owner i have met with a 335i that is a car guy. has a Jb4 tune. those 335is are "tuner" cars. i have a nothing against modded 335is, in fact i think its a pretty cool car. i know a few people who have them. its just not my cup of tea. i am the kind of guy who would want a V10 R8 over a modded GTR. also i was talking about LS engines because i was trying to show you that one of the attributes a big V8 has with modding. which is a whole different topic. |

yes there are. but those kits are very costly. you don't see to many of those M3s around. where every other STI is tuned it with a downpipe that shoot flames. if the M4 response well with tunes, lots are going to want 50HP-100 gain with software. |

Technically speaking, only the Z4M is a sports car. All other BMW M cars are GT cars. They all race in that class too

1. Insist that the vehicle should be brought back 100% stock 2. "Flag the vehicle in the warranty system" Our car was the last straw for BMW. They took a bath in HPFPs. Most from heavily modified cars like mine. They ain't playin' no more.

This has not stopped the modding scene on the forced induction Audis in any way, shape, or form. You have to pay to play. People who are buying M3s generally will have the disposable income to modify and repair if they so see fit. Engine modifications for F8X M series cars will be pervasive, mark my words. The power is too easily gained. Upgraded air/water intercoolers and downpipes will probably be out within a year of introduction. I personally know of two N54 tuning houses who will begin development of S55 aftermarket power adders the second their cars arrive. Initial tunes will be with piggybacks, followed by software, followed by a combo of both. My GT-R's powetrain warranty was thrown out the window at 10k miles when I modded it. I couldn't care less. If it breaks, it is an opportunity to fix it with better parts.
