Top Gear has been my favorite show for a few years now. My only problem is they show too many reruns here. I was watching last night and I was amazed by something and thought I would share.
They were trying to make a car called "Avantime" as fast as a mitsubishi evo(good luck). In the attempt they put the car on a dyno(which they call a rolling road)and found it had only 157HP. Original HP was 210, the car was six years old. After replacing the fuel injectors, air filter, and intake manifold they got it up to 206HP. They didn't mention if intake manfold was oem or not but knowing these guys they would have done some bragging if it were a performance unit. This just goes to show how important maintenance is. 49HP from some very basic things that are often overlooked. For those of you looking for some performance from gen1 tundras, look at the basic things first, you may be surprised.
On a side note, they were testing performance upgrades by running laps around their test track. When they added bigger rotors and bigger wheels with low profile tires they lost substancial time. No doubt this was due to added rotating mass. They also found adding a rear spoiler, which was an obvious joke(real formula 1 spoiler on a front wheel drive car) also caused a loss in time.

BTW not sure which forum this post would be best for, if any mods find a better home for it feel free to move it.
