    One thing that definitely helps the europeans is readily available higher octane fuel. Much better for higher compression than what I can get 91 octane! I think that my motor is built around safe perimeters, with great power & torque. But I know it's not putting down 300hp to the wheels, maybe a optimistic 250 though. All in all, it probably cost me 10,000. And that was starting with a built motor 2.3 ie, built top-end, so I just had to stroke it, Alpha-n, fuel injectors, fuel regulator, carbon airbox, etc.

      I also maintain hopes of being able to pass smog, with a minimium of changes!

        300 hp to the wheels? 250 hp to the wheels? did I misunderstand your post in any
        way?

          a lot. this is going to sound arrogant, but there is not a damn
          thing in comon with your typcial 285 claimed hp tms buildup.
          and said buildup would look very pale indeed when taken
          to task. Ive had better want to do a head to head comparison.
          this is one instance where adam should have responded
          SEARCH. because I am not a very secrative person, I help
          everyone to more power when I can

          BTW, one of the guys doing head to head with me is a friend,
          and he is just now building up the newest engine. we will
          see at easter (its all in good fun)

            I've probably read at least 30000 :p posts by you, John, but it still seems simplistic to me. Your typical comment is Motorsport 300 something cams, shim-under-bucket for safer high-revs, ports to 29.5 mm, your special spec pistons (Motorsport?), proper BMW header and exhaust. Is that it?

            Since you are such an expert on the BMW Motorsports' engine program, it would be nice to have one condensed, specific post covering details from the intake through the exhaust. Maybe you could even through in some comments about where the US street-build falls short. I'm not saying that would be something you'd wanna do, but it'd be nice...

                  Anders,

                  Picking parts is one thing, knowing that
                  they mechanically work together,
                  also in terms of things like: spring & cam
                  profile matched, hardness of cams
                  and tappets, weight of tappets,
                  tolerances etc.


                  It also helps to know the proper cam timing.
                  Lets say e.g. you picked some schrick
                  308/292, do we know which cam timing to use? Or are we just going to dial them in
                  to fit the pistons, and the power that results
                  is whatever it is? and what does "308"
                  mean anyway? is that the standard 308
                  or is it a custom schrick grind? (both
                  exist).


                  In your question, it sounded to me
                  like your sort of believe there is not
                  much difference in the engines.


                  When Adrian H built his, he first started
                  buying various tuner parts. When it became
                  clear what he ultimately wanted, I gave
                  him my thoughts on those parts and the risks
                  involved. He did not fiddle around long and
                  second guess. He sold off that stuff and
                  got the right parts that work together as a
                  package. Note the word package.

                  Im sure Adrian may have had his doubts
                  whether he should trust me.

                  Even when you have all the same (or nearly
                  same parts), some motors end up stronger
                  than others. Ive seen this on some that
                  were built close to mine and we did back
                  to back comparison.
                  Thats one reason I hope Adrian will come
                  to the Ring this year so we can check this
                  out.

                  one thing that Adrian has in his motor
                  that one of these big HP advertisement
                  motors does not have, is sodium filled
                  exhaust valves, 62g each. Adrian has
                  a long list of stuff actually.
