"After our first driving impression, the manufacturers' claim of 20hp & 25lb/ft torque improvement over stock seems like a very realistic figure."
The website proclaims
Its for a e46 330i.
what gets me is these companies have plenty of money to actually dyno a car to prove their products but they dont. snake oil.
I would expect a horse power increase like that to only come from a serious modification.....like chrome valve stem covers.
it could be 20hp at the flywheel below sealevel =]
they pull any number out of their arse and make it sound as fact
I agree with Kristian. It's all ********. We dino tested my 535 set up with a 20 cm long open K&N filter and 44 cm long one and compared this to the factory set up. The only increase was 3 bhp when reving it up, and at full throttle it even lost 5 bhp due to the hot air it was sucking up from the engine bay. Standard is better unless you're running a full turbo set up. The 44 sm filter sounded fantastic though, it sure gives the impression of going faster....
your just right man, like ive said before, ive seenQuote:

or on a cold day that figure might increase slightly,
like the old rule of thumb, a 10 degreeC drop in
intake temps will increase crankBHP by somewhere
around 1%, so you could be looking at a 5bhp increase
on a cold day........................every little helps i suppose????????

Ha,ha,sorry mate, It´s already got a new home, on the airbox I´m attempting to make for my ´76 twin Weber 16 Manta. They are not expensive at all as it is a universal fit filter. It cost me approx 85 dollars here in europe. Guess it would be cheaper over in the US.
