[bobby boy]

Could anybody tell me what the bhp on a 328i convertible should be cheers bob.

192bhp

Fit an old 325 manifold and a bored out throttle body and you will get 220bhp for less than £350.

On paper it is 193BHP in reality it will be nearer 210bhp. The reason it is quotes 193bhp is that there is a tax law in Germany for cars over this BHP, so you will see that BMW, Mercedes, Audi and Alfa's all have cars with 192/193BHP. The reality is these figures are a bit flexible. The 2.8 and 3.0 are not that different certainly not 37BHP different if you see what i mean

Nope, the car is definitely 192/3. It is deliberatly restricted by BMW, which is why it is so easy to liberate another 20bhp for so little cash.

Both the manifold and throttle body are restricted for this purpose. Go here www.328sport.dsl.pipex.com/
to see a few dyno plots.

Having said that he had 200bhp (adjusted) before he started modifying.
