Wah, quite far off manufacturer's claimed figures. Is it because the testing perimeters different?
Puny said:I would think that 130 at the wheels is already quite close?.. What's the margin of allowance for manufacturer claims versus actual dyno?... 15-20%?
rodders said:Has it got anything to do with what you've done to your car? ie the minor mods....
Bro, I think ours will be even lower..rodders said:Feel like throwing away my car now..................![]()

On paper:
bhp = 143
torque = 200Nm
Dyno test:
bhp = 130
torque = 178Nm
Anyone, any comment ???
the dyna chart with STOCK engine... no modification done on it. Only with the following thingy:
- BMW original 325 Exhaust
- Custom CAI with original air box, K&N Filter (cone)
Whisky_Tango said:Bro, is ur 235 exhaust a complete system from the header? 2 pipes all the way to rear muffler?
Ur lost of power and torque could be the fact tat u lost VELOCITY when minimum required back pressure is lost due to more free flow now.
Those interested in Exhaust System, please read this article. http://www.cobbtuning.com/tech/exhaustdesign/

Yo bro, mine is only the rear muffler.
last nite saw ur car park at sound bar car park. u there ?
Whisky_Tango said:Hope the article gives u some idea to mod ur exhaust system. Last time my green 320i (on paper 150hp, 200nm??) install approved Remus and decat, superchip, blitz open pot filter. Dyno at 165hp and 211nm at 2300rpm.
Later I backside icthy, when to take center muffler and convert to twin pipe straight thru. Knn... lost 8 to 10 hp.
Just sharing my experience. Spend S$400 and lost so much power.
Yup last nite was at sound bar. Saw a few of our members at the cp but later din join us though I invited.![]()

chuckky said:Hi,
Thought K&N also claims that their filters help in HP and torque... hmm... looks like BS too.
