Anybody know?

 

140 something?

I've only had mine up to 125...I think that was at about 5000 rpm in 5th.

 

i doubt a stock LS can hit 140

 

In theory, at 7200 RPM, the LS would do 162MPH

 

I hit 135 in my GS, but then gave up cause the car was too shaky with my 17" rims on, but it definately could have gone much faster.

 

I vaguely remember a Car and Driver report stating that they got an LS up to 129mph. I've only gone to 105 mph myself.

 

135 in a GS automatic?? That must have taken hella days...Honestly I don't think the speedo is accurate at those speeds. What performance mods did you have?

 

I've gotten my RS 5 speed up to an indicated 129 mph. It took some time to get there, too.

 

i had mine up to 140...........but that was with a GS-R tranny

 

all I have is an intake, over 125 it take hours to get the speedo to move....stock LS 5-sp tranny

 

I've had mine 138 on level ground. I don't believe it would push any harder to hit 140's +.

 

I get my GS-R up to 125 all the time...It still has a lot of room to go. As far as an LS goes, I'd bet you can at least get it to 130, but I haven't driven in many, so I couldn't honestly say.

 

My friend hit 135 in his ls the other day, but then it would not budge any higher.

 

bone stock RS 5spd with 141000km, i hit 131mph or 210kmh on the highway, stock everything right done to the 14inch michelin Xone's.

 

I've got mine up to an indicated 127...and that was going slightly downhill.

it did take a while, but it did it. All the car has was an intake at the time. Other than that it was stock. (except the 17" rims making it shaky)

 

the top speed with my integra 94 4dr auto when 121, is that what u are talkin about? or no, but mine was going so fast my wheel was shaking and i still dont know why.

 

well let's see

my 96 gs-r with 148hp to the wheels I got to an indicated 142mph before I ran out of room. at this time it was accellerating reeeeal slow.

So I don't see any stock LS's getting near there.

 

i hit 130 in my old 96 LS with i/h/e racing a lude on the way to Houston. Of course I lost.....

 

same here

 

Problem is the speedo becomes inaccurate once you hit the triple digit area. You can't get an exact reading.

'96 RS Integra >> I/E >> 127....

 

true. either mt or c&d (forgot which one) tested the 00 si's top speed with a radar gun and got 129 mph at 8K rpm, while my friend can reach an indicated 140 mph. that's quite a big difference. the higher you go the more it's off the actual speed.

 

Will you lose any top end by using a GSR tranny?? Also everyone seems to say its all bout the GSR... is more respect desrved to LS's?? Could we beat a gsr? They say our cars have more low end torque? And in the sport compact world in general are LS's respected... i dont think so.

 

Boosted LS's and LS's on the juice get respect very quickly....

 

yeah i think LS's get plenty of respect... a lot more than say a civic EX. Although my LS only got respect cuz it is boosted, but still... Before boost, I still worked plenty of V8... trucks! Its pretty damn fast for what it is... especially since mine is an automatic. Yes, the B18B has more torque... more usable torque to be exact. The torque curve is a lot more linear than than that of the B18C. Linear = more usable. Exponential = Less usable.

My top speed has only been about 121... but i ran out of room and that was stock. The speedo isnt too accurate, especially when you throw on bigger rims and tires... thats what many truck owners who lift it like 9 inches and add tires the size of a house on have to worry about and they all NEED to calibrate their speedos, but most dont. Unless you ran it stock or used a radar gun to measure, then your speed was probably off.
