tx_boy has HT4100 in a 4k+lb car he likely has to floor it regularly during normal driving. WOT only appplies to Northstar or Aurora 32v engines. WOT procedure applied to 4.1 - 4.9L, sbc, or early big blocks may cause severe engine damage. Although WOT is well known on the net, it is inside / back door information.
