10 tips for shaving ET this weekendimpossible 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. (Lower Center Of Gravity) 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 ever carb you can get your hands on and never get rid of a good one.

my dad told me that when he used to drag race, he'd get better traction if he launched out of the groove

some other little things too:
good tire pressures equal tire pressures front sway bar removal for weight transfer stiffened chassis (sub frames, control arms, etc.)

just my .02, but dont over drive your car. i have seen countless guys out tehre with really fast cars trying to shift fast as hell and miss a gear. Start off just normal shifting and then progress to faster shifts. You might be able to bang the gears out on the street, but on the strip, your heart is pounding and its hard to think straight sometimes.

it makes no difference unless you have a tall enough gear that requires your car to shift into over drive on the last leg of the track. Overdrive is just another gear after 3rd. Stock, you will barely used third in an auto.

Out of the Groove huh?I have been down on the Starting line for a LOT OF RACES.. Wondered WHY People do this? Hmmm Anyway.. when the track prep guys (and I KNOW THE BEST ..or so I think.. personally..) Prep the track..they will account for RUBBER IN the GROOVES to get you the best traction... HOWEVER.. if you don't have the best track prep...well I guess there would be more VHT or whatever Sticky stuff they are cutting costs on .. (I LOVE VHT want to make a Perfume of it!!!!) ... there would be more out of the groove..if you don't have good track prep..where they don't scrape regular etc..and its almost impossible to hook up anywhere really, when the track prep sucks.... HAPPY MUSTANGIN'! Holly Clark (Just my thoughts/experience) |
