Nah, it shud be fairly close btwn manufacturer's flywheel vs proper dyno
130 defintely aint the RWHP... unfortunately.
Think stock 318i shud hv about 115-120 rwhp thereabout, bigger wheels will worsen the number
Calvin, don't bother lah, your car zooms fast leh on NS....
Yeah it sucks to see the 130 vs 143, quite far.... :verysad:

Re: Dyno Chart for Valvetronic
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/
calvin said:Hi all, just to share with all the valvetronic owner about valvetronic dyno look like...
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)

Re: Dyno Chart for Valvetronic
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.

Are you sure that the readings are off the drive shaft? Even then you do have to factor in a certain amount of drive train loss right? Second, when the car was dynoed, was the loading of the dyno properly done, if not, then the readings will be screwed also... my 2 cents...

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