    Oh I see, that project seemed to take forever with no results, I gave up on following it. He eventually showed some dyno numbers which looked good. Why take it out of the E46?

    Ok, so if you are generating less heat, and it is more efficient, the cooling system in that case should be able to take more boost and it should be able to do more boost without detonating, but then the strength of the internals becomes the issue, right?

    Ive never seen it done, must be a near perfect track at the least.

    Wow that is quite a build! The real question is - how come it's sitting in storage?! You need to shoehorn that thing into a 2002 or E30. Please.

    OP, that is crazy! It went 141mph with 13psi and your were running 27psi on the street. So, do you still have the motor in storage. I see you said that you sold the car.

    I still got the motor with most the components. I am not sure if I got the balls to drive a car like that again or if I really want to face the risks of sideways action at 250km/h in a E30 or even a E36 for that matter. I have been thinking about what to do with the whole thing but nothing comes to mind. The exhaust manifold and intake was built by a very dear friend who past on so there is a lot of sentimental link to it. I have started collecting some pieces that I sold off to have a runner on a stand, worst case scenario I will wheel it into my living room hehe or possibly I am looking to give a disadvantaged youngster a chance and building a drag car.

    I still think that rig would be the mutt's nuts in a 2002 or E30, but serious kudos to you if you give some underprivileged young enthusiast a dream project (though I'm not sure it's a good idea to give anyone under the age of 25 that kind of power haha!).

    I can vouch for George & the traps. Some of those pics were taken by me (brings back memories Georgie). The other thing to remember is that we are at high altitude. Of course we lost spool & some power with that. But the one good thing is we also lose wind resistance. For a high horsepower car, the last half of the track running in thin air with less drag means some crazy acceleration. There is 17% less drag up here so one needs less power to hit a certain trap.

    Thanks for clarifying that. I was actually avoiding getting into that conversation a lot of people argued the traps sound to high. Many use those online calculators but it shows you in certain conditions it can be done at far lower power levels.
