How much should I expect my 1/4 mile to decrease when I put in the Borla exhaust and CAI I just ordered. I'm kind of curious.http://www.n-body.net/registry/pokeypanda/

I ran 15.88 stock
I ran 15.29 w/CAI and exhaust

Best $300 I ever spent

I ran a 15.3 with the borla and a k&n drop in. Its all hard to tell, there are to many factors related to 1/4 times. Elevation, driver, traction, gas weight, and especially temperature.

Yes it does. I made the mistake of going to the track with my Borla and K&N drop in when it was 95 Degrees, with a heat index of like 102 after humidity and the breeze were factored in. Ran a 15.7, and there were a bunch of cars running slow it seemed that night. Wait til I get out there when they open in March... Cool air for my CAI and Borla. Then we'll know... muahaha :thumbs:

Nitrous. It's the cheapest horsepower you can get.

1/4 mile comparison again:

I ran 15.88 stock
I ran 15.29 w/CAI and exhaust
I ran 14.66 w/N2O 50 shot, CAI, B&M, & exhaust

Best $680 (total) I've ever spent

No, I really don't like nitrous. It's not the way I want to improve my 1/4 time. I want my car to feel faster whenever I drive it, not only when I press a button.

That's how I am. I hardly ever make it to the track, but I still want a fast car to drive all the time. Aside from taking the Firebird out for a speed fix, I want the ability to run track times all day long. NOS is ok, if you like it, fine. But unless I've got all the possible engine mods done, and still not happy at the track, I probably won't be running it anytime soon.

Okay well this is where my impulsive side will show... but oh well.

I use nitrous all the time. I use it on the way home from school, from work, wherever! I just like to use it for a second or two if I'm passing somebody or something. Whenever you want it, it's there. It's not like you don't have power when you need it. Granted there are many more permanent solutions than nitrous, but it shouldn't be considered "track only".

If I had nitrious, I'd have to take it out anytime I'm not at the track, or I'd get myself in trouble. I'd be paying so much for refills, and I mean when I like something, I do it a lot. Hence my 3 liter a day addiction to Mountain Dew. I'd be blowing too much money on refills, which is not good. I'd rather blow the X amount once on engine parts and not worry about when I punch my gas pedal if I'm gonna have to refill something for $$$. That's just me though. I mean it's not really just track use, my friend in his 94 5.0 Mustang stick got trampled by a Ford Escort on juice in the middle of main street. Funny stuff. :thumbs: For me though, I don't have the necessary will power to restrain myself. I'd burn something up.

You can have the Heads of the motor ported and polished. That will give you substantial gains. Also, the CAI/exhaust/Chip will work very well with the heads. With solid headwork and the above mods, 14's are achievable...:thumbs:

*Of course your tranny will need a cooler, and a line pressure increase via the chip. Of course, the durability of the motor and parts will be compromised as you could guess.

Does anyone here have a car w/out a SC or NOS that can run in he 14's?

...no other guys have headwork... and no other guys are in the 14's NA...

*See the common connection b/w these NA 14 sec cars???;)
Check the 1/4 mile thread for their names, and check their mods on their n-body pages... heads are worth it. I wish I did them myself.

I think schweppe is in 14's too.
he should be atleast.

14's can't be all that hard to reach without juice. I mean, my best last year was 15.5 with over 1/2 tank of fuel and running bone stock. I am going to be runninng in April with a CAI and only 1/8 tank of fuel, so I am hoping that will drop me down close to 14's. I likely won't hit 14's but I know for sure I will be around 15.0-15.2 anyways, but we'll see.

So all I have to do is buy stage II heads???

you could always resort to some weight reduction too

The Naturally Aspirated 3400 14 Second Formula

Heads+CAI+Catback+AFPR-tiretread-sometrannylife=certain 14's*

AFPR=adjustable fuel pressure regulator.
CAI=cold air intake

*Requires a solid launch, minimal wheelspin, and appropriate driving, but with the ATX this should be easy to accomplish.

Noteworthies & Disclaimers
Heads will decrease MPG, more depending on flow and driving style. Tranny life will be reduced with the extra HP/lbs-ft
...I have presented a highly accurate proof, good for most applications, if you can't get your car to the 14's after these mods, don't sue me... you may have gotten a weakling 3400.
Mod at own risk.:D

Do you think all this has to be done though just to hit 14's?

NA, you will be close with the CAI, exhuast, chip and a good launch. Some cars are factory freaks, but I have NEVER seen/heard of a GAGT in the 14's without some substantial power added. (heads, SC, N20)

Some guys have come very very close with Drag Radials on the car. But to break thru heads are very effective, and you will enjoy them on the street a helluva a lot more than using drag tires.;)

Like I said in an ealier post, my best was 15.5. I was running 15.8 with my sub box so I took it out and thats when I got the 15.4. I also has over 1/2 tank of fuel. If I cut the fuel down to 1/8 tank and throw on a CAI, what do you think my time would be? By the way, my car is a 2000 SE.

With the optimal launch and str8 driving, 15.1-15.2 tops... The CAI is great, but it is not the true answer. You need more air flow throughout the whole motor, the intake will feed more air, yes, but the heads are still flowing the same. So the CAI is able to get more air than the box and colder air, good for just 5HP maybe (w/o TB, exhuast). No where near enough to get you into the 14's. Go for it and find out, the CAI is cheap anyways and will still work with heads etc. Good luck man.

FYI
Weight savings = a tenth is EQUAL to 100lbs
Every 10 degrees of cooler air = 1HP

I will give it my all but again, I do not expect to hit 14's but I do expect to be close. I have also heard about that theory of 1/10=100 pounds. But explain this to me, lol. I gained 3/10 by taking out my box and it is only 2 12" subs in a box whick is no way near 300 pounds. My R/T was pretty much the same all the way through.

Different track conditions, weather, etc. There are so many variables. Also R/T doesnt make a difference on ET
