BMW E46 3-Series M3(S54B32)와 330(M54B30) 엔진 비교 시 같은 NA 인라인 식스 실린더이고 VANOS를 모두 사용하는데도 출력 차이가 큼 (M54: ~230HP vs S54: ~340HP). 배기량 차이(3.0L vs 3.2L)로는 설명할 수 없는 큰 성능 차이의 원인이 무엇인지 궁금함.
M3(S54) 엔진의 주요 장점들: 1) 엔진 블록 재질 - 330은 알루미늄-실리콘 합금이지만 M3는 주철 블록 사용으로 고하중에서 변형 저항성 우수. 2) 압축비 - M3는 11.5:1, 330은 10.2:1로 더 높음. 3) 캠축 리프터 - M3는 솔리드 리프터로 고회전 대응 (8,000rpm vs 330의 유압식 7,500rpm). 4) 캠샤프트 프로필 - M3는 더 적극적인 프로필로 밸브 오버랩 증대. 5) 스로틀 바디 - M3는 실린더당 독립 스로틀 바디(ITB) 채용으로 각 기통에 최적화된 흡입 공기 공급, 330은 플레넘 챔버 방식.

I try to be as objective as I can with cars, not carry over any prejudices but like in all aspects of life (clothing, food, drink, electrical/audio equipment etc), there are brands that I am more drawn to and have more of an affinity/fondness with for varying reasons. So what would those 6 car manufacturers/brands be for you and why? Here are mine.1) Ford - this is mostly an age thing, as growing up in Britain in the 80s you were either team Ford, team Vauxhall or team Austin Rover and I was definitely team Ford. Why? Probably because of the Capri, XR Fords and RS Turbos and of course the

Thought I’d put a thread together on my new to me 2015 Golf RI’ve had the car for about a week now, and loving it so far, although still a few bits and pieces I hope to do with it over the next whileSo why a Golf R, and in particular an estate version…? Well, as a family we’ve needed a back-up daily for a while, as the old Nissan Leaf didn’t have the range we needed now that we live in the countryside. Mrs Leins’ SantaFe takes the brunt of the abuse - kids, dogs, shopping, etc - but we needed something for when that was in use and I needed to head off somewhere. My other fun cars don’t real

VW Golf 4가 주차 중 엔진이 켜져 있고 에어컨이 고속으로 작동 중이었으나 차 내부에는 아무도 없었음. 키가 삽입되어 있는지 확인할 수 없었음. 차량이 도난되지 않으려면 키가 삽입되어 있어야 할 것 같은데, 키 없이 엔진을 계속 구동할 수 있도록 개조된 차량일 가능성이 있는지 확인하고 싶음.

Fantastic car to aquire. I've always admired these, it's a fantastic design and the interior is just brilliant. I was wondering which car was going to need your soon-to-be-aquired welding skills.
