i have a 99 gs, the only mods i have on the car are, headers, cold air intake , and 2 3/4 exhaust.. i ve been 138.. i dont think those mods can effect how fast i can go..

you mean a speed governor?

some cars came with an electronic speed cut, others did not.

most chevys of that era were governed at around 95 mph. (not sure about there sports cars like the camaro, or the vette.)

I believe the nissan 300zx was governed, but don't know for sure, I just remember my college roomate babbling about cutting purple wire 32 all the time to get rid of it... :grin:

Hell, all the jags are limited to 155. I think they still are...

That's not every car made before 2000, though... far from it. ;)

OK. Since so many of you don't seem to grasp what stops your car from accelerating I'll explain it. You are limited by three possibilities: your gear ratios, your wind resistance/horsepower, or an electronic governor. Any one of these three stops you from continually acclerating. An electronic governor can be by-passed through various means, but the other two are insurmountable. The gear ratio limit (like that found on the new 2006 Corvette Z06, whose bhp/drag is capable of going faster than its 198mph gear limit) is slightly easier to compensate for. Your car can only spin its crankshaft so fast (measured in your car's RPM) to spin the transmission gears to make the axles propel the car. Bigger gear ratios allow for higher top end but lesser acceleration. This, however, will not over come the drag problems. In other words, you can make your gear ratios acceptable to reach 300mph, but if your car cannot overcome its drag, then you are still limited at the same top speed you have now. For instance, take the Bugatti Veyron (the current world's fastest car), it is limited to about 252mph. This car has a 16-cylindar, quad-turbo engine producing 1000bhp. you'd think that a car with so much power would be faster. Especially since the previous record-holder was the Koenigsegg CC-R with a "mere" 800hp. The CC-R could go 242mph (one mph faster than its predecessor, the 650bhp McLaren F1). With 200bhp more than the CC-R and 350 more than the F1, why is it able to only go 10mhp faster than the former and only 11 more than the latter? The simple answer is drag. Your Cd (cofficient of drag) is determined through wind tunnel tests and is the final limit to your ability to go any faster. In testing, VW came upon a limit of only being able to go 244mph with the Veyron and determined that they would either need to fix the aerodynamics of the car or add 200 more bhp to overcome that wind resistance. 200bhp to reach their 400km/h (252mph) goal when they were only 8mph short! This is a stark example of how strong wind resistance is. Cd grows with speed, too. The faster you go, the more power it takes for each small gain in velocity. It works at an accelerating rate to overcome your car's ability to gain speed.

That's because it doesn't have V-tec. dah.

I thought we went over the air resistance thing just a few posts ago...? and the electric speed cut? :puzzled:

hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm
mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm

oops, i fell asleep on my m key.

vtec!!!! i heart vtec.
and yes we did go over this a few posts ago, but note the first sentence of my last post. "OK. Since so many of you don't seem to grasp what stops your car from accelerating I'll explain it. " oops, that's 2 sentences. i'm just trying to dumb this down as much as i can since it seems to difficult a concept for some of these guys.

for me, number one, i wasnt asking if the mods on my car made me go faster, i was making a point to some of these people, that my cars modified and i still hit 145, ..

So this whole time my friend has this 93 rx7..... about 270 hp and in the low 2000 lbs.... so needless to say its pretty fast. and my bro has a 01 mustang gt supercharged with about 350 hp.... all week my friend is talkin bout how he wants to run em cuz he thinks he got a chance cuz the mustang is so heavy.... sooooo we take em out on a 2 lane country highway and my bro in the mustang is sittin a little bit ahead just waitin for him to open up the rx7....my friend hits the pedal flying by the mustang.... my bro starts goin and he is sittin back about 1 car length while we go bout 110 and i say " i think we got him"... all of a sudden VVROOOOMMMM he passes us like we r standing still.....

then we race again we r lined up goin about 150 and he just starts creepin by .... we get back to the house and he said he burried his at 180...

We gotta nasty RX-7 231mph top speed, gorgeous car.

Ive seen some cars with 1000 hp go for ALOT on ebay, the supras, i think it was 250,000
