Whats is the Hp for a stock 95ti

I think what u just wrote is correct and im with u.. !
BMW arent that dumb to release the M44 with a weaker engine than the M42 ..
the M44 is supposed to the Evolution of the M42 just like the M40 then came the M42... !

i googled it and it came out to be like 140hp didn't tell the torque

I bought a 95 Ti 64000 miles 5 speed about a month ago. It is fun, but seemed like I had to work the hell out of it to get power (Clutch is probably reaching end of life too). Once I added up the cost of adding all the Sport body stuff and Seats that I wanted, I decided to just by a Sport and found a 97 Sport (120,000 miles). Now the question. The Sport (which I just got a few days ago seems to have significantly more power than the 95. Both appear stock, no intakes, stock exhausts. Any idea what I should look for to explain the difference? I'd like to have the 95 running as strong as possible when I sell.

Individual engines may vary. My 91 318is seems to make a lot more power than when I bought it a year ago especially at the top end - I think the M42 is finally really getting broken in as it passses 130K.

Having owned both as well, I would agree with this assesment.

Just to answer a few questions for you guys on this. In 96 big brother mandated OBDII and a smog pump. These changes caused the M42 to lose a bit of power. To compensate BMW changed the stroke to add some torque to the motors to keep them up with the previous years models. The quicker reving 95 has a lot to do with not having to drive a smog pump which has parasitic power.

As far as power differences there was something on a dealership level that cars taken in for service were hooked up to a computer and downloaded a milder program which robbed them of power. A shark upgrade should help out with this. Also there was a trick in spreading the cam timing out that helped out as well.

OK, couple of problems here: I assume when you say smog pump that you must be talking about the Secondary Air Pump, which is not belt driven and therefore causes no parasitic loss. The last time I looked at my M44 the only belt driven items were the AC compressor, alternator, power steering pump, and water pump. The other thing you're talking about was a Technical Service Bulletin to deal with customer complaints of a rough idle. It involved a software "update" and a slight adjustment to the timing to smooth out the idle. The uncofirmed(AFAIK) internet rumors about this adjustment indicate that it causes a slight reduction in power, but I've never seen anybody back that up with any kind of before and after comparison.

[tigruppe]

Sorry about the pump being driven by the motor. Meant to say the addition of the pump and OBDII caused a reduction in the power of the M42 like the M50 so BMW upped the torque to try and keep the same seat of the pants feel.

As far as the software update that has been verified by a number of people arround this area, on previous ti boards and by a number of BMW techinicians that I associate with.

[bullmand]

What's the difference in HP and torque before and after the "update". I only ask because I've never seen any actual numbers. Does anybody know what model years it affected. Was it all of them?

[tigruppe]

The update affected the M44 engine in the ti, z, and 318i/s autos from '96 to '98 I believe. Ten years ago somebody did do the test on the dyno and found it to lose about 5-7 rwhp and a couple twisties. Cannot find that discussion now because it was on a ti board I use to run which I let go a few years ago.

One of the BMW techs that I have known for years was able to get the power back by splitting the cams 1-2 degrees.
