I have a stripped out chipped 4 door 325i, and a friend with a 2 door stock ix.
We swapped cars for a day so he could experience my awesome, and so that I could tell him his car was running well.
I've having a hard time knowing if it has all the power it should. I expected it to be weaker, but not as weak as it is. What gets me is that the engine is smooth, so every cylinder is pulling the same power. Also, spring maintance has been done (All filters, spark plugs and cap/rotor).
So now I'm trying to figure out what else is different. Wikipedia gives a weight difference of 160lbs. The tech section of R3V says it's 200lbs. That's a big difference, but not enough.
Is there an accepted value for how much additional drag the all-wheel drive system adds? Is it noticeable or negligible?
Has anyone driven an 'i' and 'ix' back to back and thought there was a significant acceleration difference? Are there any straight line differences between the weight and the extra spinning mass?
Thanks everyone. I don't want to volunteer to tune up and track down a problem that doesn't exist.
