Now that I have gotten everyone x-mas presents I can start getting money to repair my car. I officially decided to keep my car because I raced a 328i and kept up with it even in its bad condition. I have found what I want the exterior to look like(posted below)
no, sorry to burst your bubble monk , there is no way your gonna get those numbers from a 1.8 4 cylinder,first off without a proper dyno done, i cant believe 200hp, you cant guesstimate crank HP you need to see what your wheel HP is. get a good dyno run in (one run is relatively cheap) so at least you know what your working with before you put the mods on.
the second thing is the bolt on mods you described above will probably not give you anything close to a combined 25+whp, maybe closer to around 13-14 at the most.
im not saying your wrong , i very well could be, but i know that even a supercharger for a 318 barely gets 190whp, horses to the crank and to the wheels are two totally different things, by your calculations your saying your car with a balanced and port and polished 1.8 is faster or should be faster than a 3.2 M3 (240hp to the crank , around 200-205 to the wheels)
i think you need to throw that baby on the dyno again and post up some before and after charts when you bolt on the mods.
a 318is has about 135HP an engine balance gives it about 50HP then a port and polish adds about 25-30HP. When I first got my BMW it needed a tune up so some HP was lost when I had it dyno
When fully working it should have about 210HP then add a chip +11 then a high flow throttle +6 New exhaust +8 you get about 235hp
OK, I'm no Click and Clack here, but this sounds a little wild to me. First off, please fill me in on what you mean by an engine balance and how it adds such a huge amount of HP (and how I can do it on my M3!!!). Secondly, those numbers seem kinda high for a port and polish on a 1.8L engine.
I read the article. Intuitively, it makes quite a lot of sense for the purposes of engine longevity. I'm not sure how it could increase horsepower to the rather dramatic degree that you claimed. In addition, the article suggested that in order to be effective the procedure should be carried out weekly. If I wanted to spend that kind of money on a car, I think I would have bought a Murcielago. Where do you go to have your engine balanced in this way, anyway, and how much do they charge you each time you go?
About the Dinan numbers, keep in mind that differently sized engines respond to Dinan upgrades to varying degrees--usually based on engine size. Larger engines respond more to being able to breathe more freely. Surely one can only expect the Dinan-advertised gains for Dinan products on the larger 6 cylinder BMW creations rather than the smaller 1.8's and 2.0's?
