Some here have CPO cars, and yanking out more than a charge pipe and tune for dealer maintenance may be asking a lot. An entire meth injection system will be out of the question. Not to mention, some may not necessarily want or need Darkhold power levels. Yet. What might increase sales would be power figures on stage 2, the Pure charge pipe, and a tune. Perhaps at 15, or 17 psi. Heck, both. Especially in light that at the same boost levels increased power is expected over stock, or Pure stage 1. Is 400 + whp @ 15 psi with the above setup out of the question without meth, or filling up our tanks with 6 gallons of e85 expecting too much?

Ok, I'm having trouble understanding why these cars aren't able to make substantial power without meth/e85/high octane fuel, even with upgraded turbos. Perhaps someone can afford to educate me. Is it related to the direct injection system, or some sort of cooling issue that requires better fuel or an addition of cooling systems? I do realize these oem turbos are quite small, and even a modification to increase airflow in the oem unit does not ultimately hide the fact that the N55 deserves are larger turbo, but I came from a Honda background where I frequently saw these small 2.0l (k20) engines produce in excess of 500whp on pump gas, and much more with e85 or something like C16. So what gives?

Boost adds compression, so higher compression is the same as running more boost, but you are not able to run it through an intercooler so it adds more heat than boost does. |

To all the people saying you won't make more power on just pump, this was my result with the competitors stage 2 on just pump.
http://www.1addicts.com/forums/showthread.php?t=1003520 Obviously you can make much more once you start mixing in ethanol |
