Hay guys im wondering what the top speed of our lt1s are. our speedo say 150mph. now i had my camaro at 150 chasing my grandfather in his corvette and he was doing 170+ and i was right on his ***. the mods on my camaro at the time was lt4 hot cam and 373 gears. at the time i wasent sure if i ran out of engine or ran out of tranny or gear? i have a filling im asking the wrong question but o well.

7.0 camaro

most likely you ran out of power. the drag of the air get exponentially more at those speeds

lt1performer

ok so more power could equal higher speed. but wouldent i have to get more air in to the motor?

7.0 camaro

yeah. or make it more areo. or lighter.

if you can turn 6500 in 5th gear that should be around 180. if you can do it in 6th. thats 270 haha

lol i dont think i want to do 270 on the street im stupid and will go to push past 180 but i dont think much more

pretty sure the laws of physics would not allow an F-body to hit 270mph.

the veyron (1.5 million dollars) can barely hit 253mph ;]

according to top gear, the tires would wear bald in 12 minutes at those speeds, but thats okay because you'll run out of gas in 5 minutes ;]

I've had my tach @ 5700 in 5th and it was still pulling but I had to let off for a bend in the highway. 3.42 rear w/ 26" tires = 173mph but I figure my tach is probably off a bit so I just say 165+

I've burried the needle several times. I'd say I've been able to at least hit 160. The car definitely runs out of power before it runs out of gear. But anything over 150 is just well...stupid (yes I'm saying I'm stupid). If you haven't won the race by 120 (I think that's around the top of 4th), you've lost, that's all there is too it.

before my engine decided to give out i know ive reached 160. My only major mod was a CAI. I would say a lightly modded car could easily do 175

As stated, air resistance is exponential, not linear. You can't simply say I can do x miles per hour stock, so I should be able to do x miles per hour with a few mods. That increase of 15mph in top speed takes quite a bit of horsepower to pull off.

Look at the Veyron for example, they said it only takes a little under 300 horsepower to reach 150 mph. But it takes an additional 700+ horsepower to hit the extra 100 mph top speed of 253.

mine stops pulling at about 4200-4300 in 6th gear with 4.10s which is around 160

i hit around 160. pinned and then held for another 15 seconds or so?

You'll go faster in 5th gear.

my 1993 easily buried the needle and it only had a cai. Now its getting lt's, a pcm tune, bigger injectors(no hp gain with those i dont think), and 17x9 ws6 wheels. It's an m6, not sure what gears. What do you think the top speed will be for me?

my 93 ran out of power with 373 at about 5k in 6 but would pull all the way to 6k on the bottle and thats just to damn fast for most people

dont know if your trying to be a dick or being serious. if your being serious then sorry im just looking to see what the highest speed people have done in there lt1
