These engines were not meant to take all the torque everyone seems to want to push down it's throat. It is fine if you are a professional drag racer or nascar racer and you have lots of money to replace blown engines. But does the average owner on this forum really want to take such a chance to pay for a blown engine if you exceed the engine's limits? These engines are going to be real expensive to fix if anything has to be replaced. The other concern is how much faster you are going to go by adding just a few more horse power with these pulleys. That is to say the extra speed is not linear or proportional to the added horse power once you get to the 12 second 1/4 mile area. It is more like exponential horse power needed to get just a few tenths of a second faster. I am not saying it is not possible to break 12 seconds but it might be a lot harder than you think. Just some of my thoughts on the subject. I think I read recently in one of the popular car magazines that the new 2008 Vet with 650 hp does the quarter mile in the high 11 seconds. Welcome replies.
