So what does two GOOD 12V batteries, a 12V charger and 12V alternator cost?? You point out the total to switch to 16V ignoring the original cost of the 12V stuff. I dont think that is a fair comparison as SOMEONE Paid for the 12V stuff. It's an "upgrade" like anything else on a racear. Do you need 15-1 compression and B1 heads or could you have a racecar with 906 heads and 10-1 compression. Could you have a raceaar with a stock block or do you NEED a World block? IMO you need to make a fair comparison like anything else on a racecar.

Oh yeah K.I.S.S
