bhp loss over the years?

[bmw325mad]

do you think all older cars lose bhp over the years?
Just had my H reg 325i touring on a dyno run and is still 167bhp... no engine mods at all,not bad i think?

[DHFiS]

No. My iS still makes 136bhp after 20 years.

my 325 was running at 155 as standard. Not anymore tho

[alync205]

Some seem to loose quite a bit of power and some don't loose any at all.Had my 318iS on the dyno last year when it was totally standard and it made 138bhp,so actually gained some .It is mostly to do with how the car is minded I suppose.

[bmw325mad]

i think i heard it from Topgear and it stayed in my head since but now i know mine is still going strong

HP drop off is for 'other makes'. Any E30 engine should produce all its horses, providing the injectors are working properly, assuming adequate servicing and maintenance.

[sihooker]

Yep, my 318i is still a bit on the slow side so no change here either

Neglect loses power

25 years and 240k miles on the clock and mines still doing extreamly well and feels very lively off the line and when going in the torque band in 3rd and 4th !

How do you test if the injectors are OK?

Most injector cleaning shops can measure the flow rate and operation of the injectors however once you've removed them and taken them to the injector cleaning place you might as well have them cleaned and rebuilt.

my sport with 194000 on the clock has lost a little i had mine dyno and got 168bhp so i thought that was good.

What does that say about my previous engine Brian,dyno'd at 133bhp It's probably been reshaped into tins of beans by now!
New engine has 168bhp though so all is happy in my driveway.
