тюнинг М42

[zztop]

Ни у кого нет опыта в тюнинге движка M42?

Я пока ставлю валы dbilas (264) с чипом и усиленными пружинками. Но настроен еще на мультидроссельный впуск.

Никто не посоветует: что и в какой последовательности можно с этим двигателем делать (в плане повышения л.с.)?

ЗЫ: Замену двигателя не предлагать

почти 2 года юзал этот движок на е36, двигло однозначно

хотел его затюнить, но так руки и не дошли

тут 10 страниц про м42 и s42

особо отмечу:

If you really want to build up a M42, you should start with some 3.2L M3 pistons (86.5mm bore), some custom rods, a full engine balance, and a stand alone engine management system, like Motec, and a mild camshaft. You'd probably have to run a custom front crank pulley/harmonic balancer, since I've heard the stock M42 one fails at 7200rpm. Doing all of this to the M42 would make a fun track engine, but it would not create a torque monster since even a fully worked S42 only produced around 185ft-lbs of torque at a very high ~7.5k rpm.

If you want to be fast on the track, build up a M42.

If you want to have fun on the street, swap in a 6 cylinder.

If you want a compromise between the two, supercharge the M42.

In short, there are no really good bolt torque improvements for the M42, short of a supercharger.

почитай сцылку, там все написано

"Does anyone have any sites with some reliable info and pictures of the BMW S42 engine?
Its the same 2.0l engine used in some E36 race cars in the BTCC series.."

Я сейчас на работе, у меня половина инета заблокированна службой безопасности.

Из гражданских движков такого обозначения не было.

все верно, s42 никогда гражданским не был, двигатель специально для гонок

спешелли фор ю!

The S42 engine was a 2.0L touring car engine with a 86.5mm bore and around a 85mm stroke, which shared the same block as the street going M42. Unlike the common M42, the S42 had a more sophisticated engine management system, and had individual throttle bodies. The S42 unfortunately did not share the same valvetrain as the M42, and is a solid lifter valvetrain (possibily from the S50Euro) fully capable of over 9000rpm, but was limited to a 8500rpm redline, as dictated by touring car rules. It was mounted upright in the bay, not slanted, and ran on a full dry sump oiling system. The pistons had a static compression ratio of around 12:1, and running on pump gas, the S42 made around 280hp (and up to around 310hp later in it's life).

Интересно, S42 можно где-нибудь найти в живом виде?

Вот на этот движок я бы, пожалуй, махнул бы даже свой M42

Пока же задумываюсь по поводу доработки головы, растяжки и облегчении шатуна и об облегчении маховика и коленвала.

Хотя есть еще вариант поставить компрессор (скажем KO Performance или Downing Atlanta)
ЗЫ: Спасибо за ссылку!

[Oleg]

в живом вряд ли, тока на картинках...

что касается м42, я думаю, смысла особо замарачиваться нет, т.к. дороха...

оптимальная программа - это валы, чип, выпуск, передаточное число.

где-то 170 л.с. будет, динамика как у 325

компрессор - имхо не хорошо, т.к. есть 1,8Т у ауди и фолькса, зачем еще у бээмвэ???
