does anyone kno the top speed in a 99 ls1. just something that people are always asking and im not sure of the exact number.

 

160 for a Camaro SS

 

Hell, I've had my formula up to 167 before and it was still pulling slowly. It felt like it had a good 170-172 in it.

 

ya ive hit 150 in mine and it was def. still pulling good.

 

What's the highest everyones's had it in 6th?

 

6th would just slow you down, it doesn't pull all that well, it's meant for a cruising gear. I've had my H/C with 3:42's all the way up to ~160 in 4th. That was pulling all the way to 7000 though. I didn't want to risk going any faster. I don't know how fast it would do if I had put it in 5th

 

The speedo doesn't read past 155, so why would you wanna go past that?

 

Limiter with z rated tires is at 162mph supposedly.

 

1,000,000,000 miles an hour.

 

 

 

1000000 Mph hahaha good one

Ive had my TA all the way up to and a little past the 155 mark in fifth and like everyone on here has said she still wanted to go faster.

I read a Motor Trend I believe in 2001, it was one of those final WS6 vs. SS vs. Cobra things, and they tested all of them up to their respective top speeds, and they said the WS6 kept pulling past 165, but they didnt have enough room to test it, the SS ran out of steam at 155ish dont remember, and the poor Cobra stopped going at 140, I still have the issue I just have to dig it out of my Motor Trend box in the garage if somebody needs a citation

 

i wouldn't wanna go that fast unless I knew that the only person i was endangering was myself

 

I've gone 155 and it was still pulling hard. Just let off cuz i lost my nerve when i saw approaching headlights. Thought it could have been a cop....

 

I've buried the speedo in 4th gear in my car when it still had 3:42's.

 

THe speedo goes to 155 so how do you guys get 167? I have pegged it on a runway but I have no idea how fast that was 160ish...

 

You can guesstimate if you look at your tach, and if you know all the gear ratios on your car and the tire diameter you can find it that way

 

164 mph on the gps top of fifth

 

The SS is 160 mph
The WS6 is 162 mph according to GM

 

Yeah I have an M6, realize it's meant for a cruising gear, and know how it pulls in that gear What I was wondering is if there is enough power (in a relatively stock engine) to push the car past say 150 or 160 in that gear because there is lots of RPMs left. I took mine up to 130 in 6th which took forever and I ran out of room, but I was only running at 3,000 rpm so there is plenty of rpms left which made me wonder how long the engine would continue to pull.
