<VV> LM turbos and no lower shrouds

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
