Alright,,,,,,here's the deal.

I am, if you haven't heard, heading to the track on saturday night to get Sandy off my back. I'm shooting for a 13.99. I'm going to put the tire pressure for the front tires at 24 pounds. I'm putting the rear tire pressure at like 36. I'm going to try and WOT shift. I'm even dieting to lessen the total weight of my car. This will be my Waterloo.

My question:

For a bone stock car, (I have lowering springs, is that a mod?????) I am wondering if there is a can of something that I can put in my gas tank that will somehow boost the performance. Now,,,this can't be something where the ECU has to be reset or anything, because I don't EVEN want to start messing the car up. I am going to fill up tomorrow, and I'm wondering if there is something I can buy that will actually help the performance and not hurt the ECU or (retard???) the timing. Maybe I want to "Protard???) the timing????

If you all know of a can of something to put in the car, along with anything else that I may do to help, let me know. Oh,,,one more thing, I DO turn the car off to cool down between runs, right? I am almost certain that I do. I was practicing my launches during lunch. Cool, huh? Launch during lunch....I like that. I'm going with a 2100 RPM drop while feathering the clutch. I *think* I have all my bases covered. Oh,,,,I'm buying Shell gasoline tomorrow that is called "V" power. I have been using Chevron, but it's called Techron, and I just have to think that something called V power has got to be faster. Both gasses have a 93 octane.

I was at 14.4 last time, so all I have to drop is .4. It seems like this is attainable.

 

a few answers...the name of the gas is not important, 93 octane is 93 octane. The thing you put in your gas tank to increase your performance is called race gas, but I think what you're thinking of is octane booster (i know the company called nos sells it). I have never used it, but I hear its BS. Like I said, I dont really know. And 0.4 seconds is a LOT to drop, even though it seems like a trivial amount of time, its a very significant amout in a 1/4 mile. And yeah, lowering your front tire pressure is a good idea for a dragstrip, I dont know the exact PSI that you should set it at.

 

Yeah,,,I was thinking about octane booster. Nothing like will work, huh? Rats.

It doesn't seem like .4 is that much of a time difference, but I guess it is. I've only run three runs, and my times fluctuated from 14.4 to 14.8, I think. I would like to *think* that by my having the car longer and learning more how to launch it would help cut .4 seconds from it.

.4 is really that much to cut, huh? I just hope I don't get any slower...

 

NOS did work its just that retards decided to outlaw it. The octane boosters mostly sold are toulene based that are basically like puring paint thinner in your car...which works to some extent but if you are already running very high octane race gas its kinda pointless to put more on top of it...i hope that made sense...

 

no,,,,I'm not running high octane race gas, I'm just running 93 octane. I wonder where I would find race gas in this one horse town that I live in. Do the Amish manufacture it and sell it? They are big around these parts.

Those amish people have got to be using something to be able to throw those barns up in only one day.

 

Here's a good place to start.

Good grief,,,,I just checked both those sites and there isn't race gas within 300 miles of where I am. You can get a deer stuffed, or whatever the hell they call it, within .000002 miles of anywhere here, but you can't find race gas within 300 miles. Sheesh.


thanks for the help, though!

 

Ok, I'm gonna do you (and everyone alse reading this) a solid because I want you to succeed.
Here's a few tools from my toolbox.
First; don't worry about octane booster if your using 93 octane with a stock engine.
Second; try not to have more than a qtr tank of fuel. Gas is weight too.
Third; your tire pressures are in the ball park, but you could go higher in the back (40+) and may want to try 23-22 front.
Fourth; if you're going during a test and tune and will make a lot of runs and have enough time to experiment, start with a 15-18 hundred rpm launch, get the clutch out quickly and let the motor do the work. Also, shifting the 1-2 a little early like at 55 hundred will not really hurt you but hold the 2-3 and 3-4 to about redline. Work on the 60 ft time, and all else will fall into place.
Fifth; clean the car, dont take un-needed stuff. Remove the floor mats, lay down the rear seat backs, run the passenger side seat full forward and full tilt forward. (lightens car and brings CG forward and down which lessens weight transfer to the rear) I even scooch the driver seat a couple of notches forward because I'm 220 pounds of ballast and it also gives me a better feel as if in a race car now and not my regular driver.
Sixth; use Redline water wetter available at Pep boys or other like places. It dropped my temps about 5 degrees.
Seventh; run the heater on full on the return lane and driving through the pits to help further cool the engine.
Eighth; turn off all electrical during the run like the radio, a/c, fans, lights etc.
Ninth; hold rpm's steady on the launch. No revving up and down.
Tenth; leave on the last yellow. If you see the green, you're too late. This will not help the e.t., but will help you beat the yahoo in the other lane.
Elevendieth; print this and take this with you for good luck!

Matt :-D

 

good run down matt... the biggest problem that wasnt addressed well imo the biggest for our car... LEARN TO LAUNCH go out to a cutty road and launch untill you feel comfortable. i was practicing at a higher rpm than i actually use in a real race and at the track cause if i can get a 2600rpm launch down on the track then when i try a 2200 at the track it sould be about the same. good luck man.

 

You're getting some good suggestions there wordslayer. I agree with all. You might even be slower with race gas, without the advance necessary to need it. 24 psi is a good starting point. Octane booster, no matter how strong - won't do anything unless you need the knock resistance And can change your fuel maps.

Skip the WOT until you at least get stage 1 or 2. They have the boost hold feature, and with a stock ecu, you'll get little benefit out of it. Learn how to shift fast - that is your best bet.

I wouldn't turn the car off to cool between runs unless you have a lot of time. let it cool for 5 minutes after running it hard before shutting it off. It needs the coolant and oil circulating during that time. A fan switch and 180 thermostat will keep you down around 180-190 and running hard at the dragstrip.
