Functional ram air, cowl types work well at higher speed without adding too much drag. Might want to look at least at a front spoiler to get the air out from under the car too, within 1/2" of the ground or it won't work very well.
As for horsepower, more is always better.

All cars have what is called a "road load power" curve.
It's basiclly a function of speed (or RPM * some conversion factor)cubed.
All engines in these cars have a horsepower curve that is a function of RPM.
The point where these two curve cross eachother is the car's potential maximum speed, period.
To actually achieve this top speed, the power curve must be crossed at it's maximum, this is why cars have gears.
The most effective way to reduce road load power is to lessen the cars air drag, either by decreasing the frontal area or decreasing the drag coefficient.
This means removing side mirrors, trim, making sure the car's roofline is level with the ground, ect.

Hey guys this thread is old, and lame, let it die.

I thought all cars had fireball explosions when they wrecked. Damn you HOLLYWOOD!!!!!!
It sounds like your wanting to build two seperate cars. One thats just a mightly low end ride, and another thats some high RPM high speed track star.
First off, if your car can go 110 in the 1/4 consider yourself lucky to have such a fast car especially at 18. Despite what is seen in movies it takes a bit of work for a car to even see 13's in the 1/4 let alone 12's and below.
If your motor isn't pushing past 4500 RPM it just doesn't have the power/sustainability to spin it and maintain it that high. If thats the case, then you DONT have a car that goes 110 in the 1/4. So far, your information to solve the problem contradicts many aspects of the problem itself.
What you need to do is first, decide if you want a 1/4 mile car OR a track, rally racer. They are two different beasts with two very different needs.
Second, get a functioning speedometer (if only to tell the cop how fast you were going).
Third, consider the aerodynamics of your car and decide if its really suited for top speeds like that. Also consider suspension and brakes. You want to successfully come down from that speed, as well as get up to that speed correct?
Speeds of the nature you are talking about dont come cheap. Your going to need more horsepower, more gear space, and a better sense of your car.

I am trying to figure out why you need a higher top speed. You will not die faster when you wreck.

I'm more curious about the "breaking off the speedo needle bit"...please tell us more.
What make / model car is this?

|flipp121||yea seriously guys, stop ragging on the man, lighten up. Everyones gone fast in cars on the country roads, no need to get all high and mighty, the whole point in having cars without speed regulators is so we can go fast in them god......|

|Brian Morency||ok now everynody has the idea that i am a speed racer flying down the public road with no consideration for life. no thats not at all how it is i drive normal on public roads even getting passed here and there for going a couple under sometimes. even get yelled at by police yelling "theres a gas peddle". what i am saying is i was trying to get this car up into high speeds for larger races other then 1/4mile all the time and circle tracks. im more into rally racing then drag because it tests the driver and the alll around car more then going in a straight line for a couple seconds.|

|club327||Brian, you seem like a decent person. I'd hate to see you cause a fatality whilst speeding, because that would not be an accident. It would be viewed upon as a crime and you will be held accountable. Even worse, would be the thought of having taken someone's life due your stupidity. Speed limits are'nt set for those who are unable to drive fast, they're there for everyone. They're there to protect you, me and our friends and family from unnecessary carnage. Speeding is irresponsible and will eventually force the us to drive cars that are zoned (via satellite) which won't exceed the speed limit - no matter how much throttle you give them.|

|72elcamino||Croz thanks for the point. My thoughts exactly. My car has a 5800 redline, 3.54 rear and .75 final drive theoretically 170 MPH + or - a few. This is a new combo for me and am still working the bugs out but will be very suprised if the car ever tops 140 assuming I have the balls to try it.|

Also, something you might find interesting.... A top speed calculator. This will tell you how much of a factor wind resistance is. Now, ignore the fact that the guys is talking about a double digit horsepower import and focus on the math.
Top Speed Calculations
That site kind of leaves out how gears figure in except for the first little part about "theoretical top end" and even then it is really behind the scenes...
