And the 6258. As long as we all are in agreement that you are bored and have too much time on your hands. Stock 1.6 equals 2554. I almost went 2554 myself then realized I am not a poor and bought a EFR like and adult.

I admit I was high on pain killers post surgery when I clicked "buy now." My original opinion still stands though.

Well, maybe I should make a new thread then, because the first couple of pages is utter crap with old data and calculations. And since I will probably introduce the EFR's into my graphs/calculations then it would probably be a good idea to post it in a fresh thread. Just to keep it more clear to everybody.

Would like to hear everybody's opinion about that.

If we're all being needy I would be interested in a theoretical boost curve that would be needed to maintain 225 ft/lb of torque throughout the rpm range, on a 1.8 with a GT2560. I assume you'll run out of flow needed to keep raising the boost at higher RPM, but the shape of the curve would be a huge time saver on the dyno once I get my pile together.

to be fair it required an IM and larger TB, but that was the only change between the bottom plot and the two above:
