top speed of a head/cam ls1?
what should it be im not talking trap speed im talking 2 mile stretch what kind of mph should it top out at in a auto with 373s
|
6000 rpm would be ~175mph with 3.73's in 4th gear...stock speed limiter on most ls1's is 160 but with a decent heads/cam setup you should be able to theoretically hit that at the very top of 4th gear.
|
we just did one down here and it went upwards of 180 cause the dyno shut down once it hit the 180 mark
|
They dynoed an auto in 4th gear? Or were they just trying to see what the top speed would be?

also a dyno doesnt load the vehicle nearly as much as on a 2 mile stretch of road would...not to mention wind resistance.
|
we had already dynoed it so we wanted to see what top speed would be, and yeah i definatley know what youre saying about the wind resistance.... just be nice to have a 200mph camaro lol

http://www.ls1tech.com/forums/showpo...0&postcount=38 this guy's gone 178 with stock gears in 5th gear through an m6 obviously. This was a medium(224 duration) cam only setup

Way back when I was bolt-ons I went 150 in a 2 mile stretch on the street. I'm sure if I had the set-up I had back then I wouldn't have any problems hitting 160-170, but I would never do it. After doing 150 on a deserted backroad at 3 am I decided to never do that again. It's too dangerous.

i would suggest you look up ht eeast coast timing association. they run at an old airport in maxton , VA. it is about a 1mile shot on nice concrete with plenty of shut down and bail out area. :)

i kid you all not, but with just a lid/catback free mods m6 stock gears, had the speedo pegged in the T/A with the tachometer reading 5700 rpm i wish i had a gps or something. dunno how accurate this site is for high speeds, but i went on http://www.f-body.org/gears/ and it said 172mph and never again will i go that fast!! (just one of those things you know, i had to see what the car could top out at). Before the 4.11s, hitting 145+ was not a problem. But i'll stick with 1/4 miles now its a lil slower that way
