How can I get more speed out of my car? Sign In

1995 Nissan Sentra (5-speed manual transmission)
4 Cylinder (sorry, don't know the size in liters) :(
127k Miles

Ok... I know that I don't have a muscle car or anything, but I was hoping for suggestions on how to make it accelerate faster and reach higher speeds. Right now... I can do 0 to 60 in 16 seconds, and I'm not entirely sure how fast it can go, as I've never taken it over 105. I was hoping someone could tell me if buying premium gas and/or octane boosters would help significantly, or if you had come across any other products that had helped. I appreciate any help. Thanks Smile

Sorry but I don't think a post like that belongs on this forum. You don't even know the engine size and want to make a regular car do things it was never intended to do - talk about unsafe!

There are no additives or even plain use of premium fuel that will make much difference if any....

Make that crackerbox as light as possible. Remove as much weight as possible, the spare tire, jack, etc. Get more air to the engine, new carb set-up, cold air intake. Replace stock exhaust with header. Want to go faster in the quarter mile, go with shorter rear tires. Want to go faster all out top end, highway, get taller rear tires.

What good is it going to do to change the height of the rear tires on a front wheel drive car?

What are you going to do with a carb setup on a fuel injected car?

Right you are. Change the height of the drive tyres.

I'm going to get rid of the fuel inj and add a couple of side draft carbs.

That's both crazy and against federal law.

That is a computer controlled car. You can't just ignore that and mount carburetors on it. Everything is tied together and has to remain working.

There are several high performance cars 'out there' today. Sentra isn't one of them. Tire (tyre) size isn't gonna make a hoot of difference. Have you checked out the new Mustang, Challenger, Charger? Not to mention some of the exotics.

Well, automobiles do go faster down hill. Tires, I knew that. Old habits are hard to change.

They are quite expensive compared to a used, paid for automobile to hop up.

Changing Tyre size does the same as changing gear ratio, okay, not as drastic a change but some.

It's pretty obvious that you may be out of touch with modern computer controlled cars. Most of them have ABS brake systems now and you can't just change the tire size on a couple of tires.

As I understand it, tyre size shouldn't matter, the system senses loss of rotation or lock up and relieves pressure to that brake

No, your wrong. Tire size has everything to do with it. ABS reads wheel speeds and compares them to each other. A smaller tire will turn at a different speed.

Yes, that can have an effect but a much smaller one.

From About.com:

ABS Brakes and the Facts

The ABS is a four-wheel system that prevents wheel lock-up by automatically modulating the brake pressure during an emergency stop.

Anti-lock Brake Systems (ABS) operate as follows:
  1. When the brakes are applied, fluid is forced from the brake master cylinder outlet ports to the HCU inlet ports. This pressure is transmitted through four normally open solenoid valves contained inside the HCU, then through the outlet ports of the HCU to each wheel.
  2. The primary (rear) circuit of the brake master cylinder feeds the front brakes.
  3. The secondary (front) circuit of the brake master cylinder feeds the rear brakes.
  4. If the anti-lock brake control module senses a wheel is about to lock, based on anti-lock brake sensor data, it closes the normally open solenoid valve for that circuit. This prevents any more fluid from entering that circuit.
  5. The anti-lock brake control module then looks at the anti-lock brake sensor signal from the affected wheel again.
  6. If that wheel is still decelerating, it opens the solenoid valve for that circuit.
  7. Once the affected wheel comes back up to speed, the anti-lock brake control module returns the solenoid valves to their normal condition allowing fluid flow to the affected brake.

I don't believe tyre height come into play in any of this.

OK, look, I've had enough. I'm not here to debate with people giving advice about things they know nothing about. I guarantee you that tire size has a major effect on the operation of ABS systems.
In the future, please only give advice on subjects that you actually have experience in.

end of debate

Fair enough. Cheers!

P.S. I worked on Anti-skid brake systems in the Aerospace industry long before technology evolved to allow them in automobiles.

Fliptail;
Gotta add my two cents worth; If we are talking four wheel ABS, different tire sizes in front and rear WILL make a difference, as the circumference of the two sizes will be different, causing the wheel speed sensors to get conflicting info. Can't vision anyone taking issue with that. If it's a four wheel or all wheel drive vehicle, you are going to experience transfer case issues with different size tires. Improper tire size will affect transmission shifting as it will change VSS readings to the PCM. So, now days, it's best to just leave things alone. That was actually three cents worth. Sorry.
With that said, putting LARGE tires in the back and small tires in the front will make your car go faster as it's always going downhill.
