Chuck -- that is cool ... I would never expect you could. I do
suspect 0-60 is harmed :-) as well as 1/4 mile? And I bet that is
not a "street car." But compared to a modern car that is no
fast. My 4 door Lexus Sedan could be set at 155 on cruise control,
up or down hill. Same with my (former) Caddy. Takes the fun out of
fast. Have a Land Cruiser and pickup now that easily do 130 and are
only limited because I put AT or MT tires on them instead of high
speed tires. Either will go more. And fast cars do over 170, even
over 200 these days. I will only admit to exceeding 175 on a public
road once ... and I'll never do it again (too dangerous for other people).
And you made my point with your truck ... just like I was unwilling
to tear mine apart to get more power. Chipping and exhaust and
intake does a lot for minimal expense and damage. Of course mine was
not as strong as yours is stock. Yeah, they are all now in the 400hp
800 lbs/ft now ... and you can still chip them! E
