"10 Tips for shaving ET this weekend"
|
1.
More RPM - I've found that it’s just about impossible to
have too much (higher number) gear in your car if your goal is the
lowest ETs. Just keep adding gear ratio until you stop gaining ET,
even if the MPH falls off. Remember: racing is usually ET not MPH. 2. Jetting - If I had to guess I'd say that 80% of all race engines are jetted too rich. Some of the signs of a rich setting are an engine that misses or surges. Try jetting down two sizes and see what happens. Learning how to read spark plugs is my best advice. 3. Ignition Timing – Go up or down two degrees and make a test. I’ve seen engines tuned with just a couple of degrees too much timing lose 30hp, so don’t think you can’t have too much. 4. Oil – If you aren’t using synthetic oil already, try it, it’s worked every time for me. The other big thing is oil level, on a wet sump engine too much oil is a killer. No engine needs more than 6gts, no matter what the pan manufacture says. In fact; too much oil is bad. 5. Shift Points – If you’re going to miss your shift point, miss it early. A late shift is an ET killer, especially in the lower gears. Here’s a test: If you seem to really be knocked back into the seat after the shift, you’re late. The Reason? Your body went forward before the shift because of lack of acceleration. 6. More Traction – Obvious subject I know, but here’s one I’ve seen missed more than any other traction aid: Weight. So many people are afraid to add weight to their car, but I would guess that 80% of cars could benefit from weight in the trunk. Don’t take my word for it, give it a try. 7. Lower Coolant Temp – With all other variables being the same, lower coolant almost always makes more power. There are a lot of ways to lower the temp and I can’t mention them all here, but a problem I’ve seen more often than not is low coolant level. Make sure the radiator is full. 8. Kill The Accessories – A water pump takes 10hp to drive, an oil pump takes 10hp and the alternator can take up as much as 35hp. Use a low drag water pump or electric drive and put a switch on the field of your alternator to turn off the drag during the run. 9. Aerodynamics – Now I know changing aerodynamics of your car is not a simple thing to do, but there is one quick modification that I’ve seen work more than once; Lowering the front end of your car. I’ve seen drag cars pick up as much as .01 of a second in ET and 3 MPH in speed by just lowering the car two inches. 10. Test Different Carbs – Carburetors all have their own personality and some just seem to work better than others. Buy two carbs that are exactly the same and you’ll have different results. My advice: test every carb you can get your hands on and never get rid of a good one. |
Improve your "Finish Line Driving"
by Sal & Peter Biondo

I
never claimed to be the best finish line racer out there...But, on the
same note I've seen people out there who are worse than me. But, for
some reason or another, I've had dozens of people come up to me and
ask me how they could become a better "Finish Line" racer. Well, the answer is simple, I think. Race as much as you can, and with the experience you gain, in time, your "Finish Line" driving will improve. I'm only kidding, I would not make you come to this section and just tell you to race more often. I really did think of a method to improve a racer's "Finish Line" driving. For the most part, it is best applicable for "Super" racers, who make time trials alongside racecars that run almost the same E.T. as each other. What I suggest is this: when making your run, always check out your opponent as you are headed down track. (Of course, don't do this if you are fighting the car, or there are some severe side winds present! I'm assuming that everyone who enters this section is an experienced drag racer, and I don't need to give out driving lessons!) When you approach the finish line.... that is where I suggest you pay the most attention. What you should do is take a look over, and see where you are in comparison to your competition. Keep a mental note of that distance, and try to decide who got to the finish line first, and by how much. Decide on a number before you pick up your time slip, and see how close you can get. If you do that all the time, you may get a better idea of what's going on at the finish line. I can't tell you how many runs I see from the finish line, even during time trials, and I see racers looking straight ahead. Maybe sometimes you need to keep your eyes on the guages, or other times you can see well out of your "peripheral vision", but when its real "tight" during a time run, I'll always use that time to try and learn something. This method of guessing who got to the "stripe" first, and by how much should be done during eliminations also. I know it's probably the furthest thing from your mind when you are at a big race, but think of the long term benefit it could have. For dial-in racers, eliminations are probably the only time you can practice this method. I know in all my past experience of making time runs in brackets and Super Stock, I've rarely made a run with someone who ran within a couple of hundredths of me. |
