my car z28 '00 , is the spoiler a big factor if im gonna go fast ??

i mean .... it help in the aerodynamics and that will creat an low pressure area behind the car? ..

so can i say the SS's spoiler is doing better in aerodynamics fact.. and thats why it helps in extra hp


thanks in advance

 

Not really ... you're probably better off removing it and saving the weight ...

 

The spoiler is just there for cosmetics.

Remember the Toyota Supra with that big spoiler that was as tall as the car? THAT spoiler was actually in a position to be effective.

 

what are you talking about "it helps in extra hp" ???

What extra hp are you getting from a spoiler?

Ya know, if we could remove them and keep a smooth line I might of considered that.. hehe

 

Is there a functional spoiler for the LS1 ??? It sure as crap could use one. My car feels like it wants to lift off around 140 mph.

 

why would you take a spoiler off a RWD car? thats just less weight WAY behind the tires which would mean more tire spin

 

Theres a lot of theories here that are completely wrong... Firstly any aerodynamic device can have an effect on vehicle characteristics at speeds as low as 15 mph... Yeah you probably wont notice it, but it does. That theory about the big supra wing?? Just because its high doesnt make it better. In fact that wing is just as useless as the Z28 wing. As for the Z28 wing its prettymuch flat It has little or no aerodynamic effect on the car due to that fact. The Trans Am spoiler has somewhat of a rake to it, and the TA has a lower coefficent of drag than the camaro. Any advantage the TA has is negated by the rear spoiler.... UNTIL you reach fairly high speeds. The angle of the TA spoiler is actually a little too low for high speed driving and due to the shaping it will actually cause lift! (by high speed I mean over 170mph). The lip on the end of the Camaro SS wing would probably keep the car more stable at those speeds, due to the steeper angling of the edge of it, however the Camaro is drag limited at about 160 mph. Either way neither one is a true aerodynamic device with the intention of creatng or adding stability, they are basically just for show.

 

Spoilers can not make that big of a differance.

Spoilers like the one above have been proven to add downforce at higher speeds. The manufacturer also claims the SCCA has approved it for competing cars. You should check out the sponsor that carries this... http://www.fbodymotorsports.com/ ...there's a little more info on the site.

all bs till 150+ i read a lambergini(i cant spell) where even most of the ones on them are for looks.. and one only ones that do work are the 200+ top end HUGE ones...

 

I totally agree......

 

fastest ive gone was 143+/- and the car felt fine.. i was more afraid of the road(if you have ever been to new orleans, you'd understand why....)

 

so you're saying that because the supra wing doesn't have some sufficient rake to it, that it is basically useless? i saw a special on the mustang cobra r, and the guy being interviewed said that when the wing was being designed that the greatest amount of downforce while creating the least amount of drag was the idea for the wing. and as far as i remember, that wing doesn't have a severe rake to it either. maybe it just has a sufficient amount of angle to it and is properly placed in regards to the car and the airflow.

then there's the wing on the infiniti g35 sport coupe that really doesn't have much rake whatsoever but is beneficial aerodynamically for the car...of course, especially at higher speeds.

so is a large rake on a spoiler REALLY necessary for it to be beneficial for helping to keep the rear end set at higher speeds?

 

although i think lamborghini's are better built to where the entire car helps keep the car planted so that it doesn't strictly rely on the spoiler for downforce....

 

Youre right, thats why small lip spoilers are all you need in some cases for sufficent downforce on a full bodied street car. My Point was just because the Supra wing is this big shopping cart thing doenst mean its nessicarily good. However, The faster you go the more of a rake you need to get the same downforce, however you also then require more power to reach that speed. AND wing shape comes into play also (hence the Inherent problem with the Trans Am stock wing at high speeds). Im no aerodynamicist, they pay those guys a to of money to figure out the best combonation of rake, shape, etc, for cars like the G35 and Cobra.

My point was everyone always thinks that Aerodynamics only come into play at high speds and its just plain not true, and even the smallest things (side skirts, different shaped rear bumper, etc) can have an effect on downforce, besides a rear wing.
