I agree it would be a good idea as well. I've been looking at the Detroit TruTrac, I can get one for $382, which isn't too bad of a price.

Having your rev limited at 6800RPM makes all the difference. Since my car is stock internals (besides comp pushrods) I can't rev that high. When I'm racing I always shift right at 6,000RPM. With my tire size, I'm limited to about 112MPH in 4th.

Here is where I get my numbers from:

http://www.f-body.org/gears/

Its a very useful tool. When I put in your tire height and gear ratio, it says your 4th should top out at 126MPH.

Are you running a cam or stock cam??? Surely even with the stocker you should be shifting at 6200-6400

This thread is a waste of time. If you want a stock car buy one. These are extremely basic drag racing principles that have been around since automobiles were first introduced. And yes,I did graduate high school, but I am a hillbilly. If you go from point a to point b in less time your car is quicker,faster or whatever terminolgy you would like to use. When drag racing you can't say I lost, but my car trapped higher so it is faster. Winning is Winning. SOME PEOPLE JUST WANT TO ARGUE,AND BRAG ABOUT THEIR COLLEGE DEGREE. BUT HEY,IM JUST A DUMB OLD COUNTRY BOY.

why is this thread still going? the op doesn't like 4.10's in a 6spd and is comparing his t/a to a cobalt lol

Not everything is cut and dry. There are plenty of instances where having shorter gears isn't beneficial.

You are obviously very limited in your understanding of the world, so I'm not going to waste my time trying to have a discussion with you.

Plenty of guys go back to 3.42's once they upgrade in power because they don't need the 4.10's anymore, and they only cause traction issues for street cars. Not that you would understand anything about that though.

Obviously you didn't bother to read the thread then. If you read it, you'd understand I was directly comparing gear ratios between two cars. You're just here to bash and act like an immature idiot. Go away.

If your making power you can still run decent times on a high gear. My best friends bone stock '98 SS, with the exception of Pacesetter longtubes and 26" drag radials and a tune, ran a 11.49 @120 mph on a 150 shot with a 2.73 gear last year. I agree that a NA cam only car needs a deep gear but, if your making power you can still run decent times on a highway gear.

Sooo

3.42's or 4.10's ???????

01ws666

Wow good luck to he OP... Ignorance is bliss I hear...

Wesmanw02

iTrader: (4)

Bought a set of 3.42's. Sick of the 4.10's, too much gear for the engine size and available traction.

01ws666

Ditch those sumitomo's for mickey's and you will like those 4.10's again when you just doubled your "available traction" trust me they do make you faster with traction...

Wesmanw02

iTrader: (4)

Sumitomos?? I have Nitto 555's, 285/25/18's out back.

Don't get me wrong, they hook very well overall, but they aren't suited well to hard launches on the street or track.

I still have a stock sized rear, so MT's aren't exactly on my list of upgrades.

Yeah... when I had my 4.11s, it was a blast.

Gotta man up to a real pair of tires if you want to run big boy times.

Its a street car, not a drag car. Needs to be streetable. Mickey Thompsons or other drag tires are not street or wallet friendly.

I use ET streets as my dailys, so yes they are VERY much streetable. You can't ask to be fast and be cheap in the same sentence. If you can't afford to shell out the $$ for tires, stick to a taller gear but don't cry about being slower.

Speed = $$

It is what it is.

Wes,
After reading this entire thread I think I understand what you're saying, and I also understand what others are saying.

You're saying- Gears are only going to help get into the powerband in first gear (quicker start), then through the shifts it will stay in the powerband and not produce any more "power" because gears don't affect how much HP the engine produces.. Correct? So by what you're saying bigger (numerically) Gears are only helping in first gear/launch/ powerband. And after that it doesn't matter.

Well here's somthing you should consider because "in part" you're right. -- I've been thinking about this all day- LOL

Gears do help get into the powerband, help with launch (assuming sticky tires), and help through 1st gear.

BUT, and I mean BUTTTT --take this into account:

after the launch and first gear when you're accelerating through the next gears (2nd, 3rd, 4th, whatever) bigger gears are going to help you accelerate faster through that gear just like they did through 1st. Which is why gears make a car faster (The gears enable the engine to rev faster), but the trade off is less top end and greater cruising RPM.

Gears help acceleration through all gears (meaning shifts), and make a car faster not by making more HP, but allowing the engine to do more work faster.

And chill I'm college educated LOL-- this is just how I see it and I think I understand what you're saying. But I don't think you're appying it (gears/torque multiplication) to all the shifts outside of 1st.

And btw

Yes, pretty much

I agree with your reasoning.

However, tell me if this makes sense to you as it does to me:

With 4.10's gears and a 25.85" tall tire, for example, you will travel from 63MPH at the redline (6000RPM) in 2nd gear to 87MPH at the redline in 3rd gear, for a total of 24MPH gained in 2nd gear. With 3.42's you accelerate from 76MPH (6000RPM in 2nd) to 104MPH (6000RPM in 3rd). Thats a difference of 28MPH. In both examples, you are making the same HP at the same RPM. So in other words, you accelerate faster with 4.10's in each gear, but you gain less speed in each gear, which should basically even out with the 3.42's. So although your RPM's rise faster with 4.10's, you gain 4MPH less, which is definitely critical to acceleration.

Its cool

I appreciate the educated response instead of just bashing like some people in here...I'm college educated as well, having been in an engineering program. Let me know what you think of my response above.

that's a tiny tire dude. no wonder you don't have any traction
