    Go up ^^^ to the top black bar and study the entire Cadillac Technical Archive. A WOT exercise can be done any time you feel the urge and traffic conditions permit. The idea is not to abuse the engine - simply to exercise the engine. Car make/model is immaterial - are Corvettes generally lazy ?

    what are the speeds for 1st gear, I already have speeding problems and 75 is too high here in illinois, hell 65mph will get me in trouble, that's why i didn't do a WOT yet

    First gear is not going to help you much. You either need to get on one of the expressways late, when there is very little traffic, take a ride out in the country or forget it.

    Remember, it's RPM not speed. If all you can do is 55, then wind it up WOT to 55 and let it back down to 20. You'll basically accomplish the same thing. Just pick a time and place where traffic is light.

    Re: Love the power of my 4.6

    WOT = An engine exercise procedure during which the engine output power is brought to maximum, high rpm is reached in a particular gear, then the engine alone is allowed to pull down car speed by maximum forced deceleration.

    Find a quiet stretch of road or highway. Warm engine (greater than 10 mile drive previously). Put the stick in 1 and leave it there. Clear traffic and road ??? From a slow rolling start, stick your gas pedal foot through the firewall and leave it there. The car will accelerate to redline shift in 1st (about 40 mph or so) and automatically shift to 2nd. When you run out of safe speed or the engine rpm gets close to 2nd gear redline shift (80 mph or so) - flip your foot off the gas and let the engine pull the car down to <20 mph. Fun ?? Lots of black smoke the first time ?? Clear the road and do it again.

    The high power acceleration heats the combustion chambers and creates maximum exhaust gas flow, cleaning ports and piping. The forced slowdown creates maximum cylinder vacuum, unloading the piston rings and allowing them to shed carbon and gunk. The transmission is "smart": It will NOT let you break anything. With the stick in 1 you say "This is my preferred gear". The transmission will stay there until it needs to shift at redline. You can do exactly the same exercise in 2 - but part of this drill is to create the forced slowdown after maximum acceleration. If you wish, you can go all the way to fuel limiter cutoff with the stick in 1 - but the transmission will shift up at redline (these cars will do way over 130 in 3rd) and let the transmission brake the car back down to wherever you want, then you shift to D. TCC will never engage under heavy acceleration or high speed operation.

    Speed limiters: (tire rating on the driver's door sticker)
    S = 112 mph
    H = 130
    Z = 149 +

    Most of these engines have an rpm limiter in P or N - you can't rev the engine past 4,000 rpm unloaded.

    Is there a time function here? Why not start in 1 and hit redline and than decelerate? Why do u need to hit 80 in 2nd gear? If ur car is fully warmed up, start in 1, accel to 6k rpm or so and let off gas?

    Re: Love the power of my 4.6

    Everyone puts WAY too much thought into this. Yes, you can use 1st, but you won't stay in 1st very long (try it). It will wind up to redline in nothing flat and shift into 2nd. The only objective is to keep it at WOT as long as possible, thus second gear vs 1st and then let it decelerate as long as possible (80 down to 30, 40 or 50). NONE of this is set in stone. 80 MPH is not critical either. It can be 70 or 60 or even 50. Just wind it up at full throttle and let it back down.
