Whats some of the tricks for getting the last little bit of mph, e.t. out of your car. I am going to be shooting for the smallblock record in F.A.S.T. this weekend at MIR. I am going to need every little trick I can find. You always hear people say they have there car " Set on Kill", what the heck does that mean? I run the car out everytime. Should I be thinking of thinner oil, etc. etc. Does changing where the car goes into staging beams make a difference on et.? Any help or ideas would be appreciated.
Car is 71 Duster, 402cu in stroker smallblock, factory heads, intake, exhaust manifold, thermoquad. All worked.

Stage as shallow as possible. Put as much air as possible in the front tires. Synthetic lube in everything. The stock guys run less oil in the engine. I might skip that mod. Loosen up the accessory belt so it will slip at higher rpm.

0w20 synthetic oil, bring a big fan to cool the engine between rounds, synthetic light weight gear oil as thin as you dare, pack ice bags with shaved ice all around the intake and carb between rounds, drop the t-bars till it is almost sitting on the bump stops (weight transfer in the 60ft and aero dynamics at the fast end), have the alighnment double checked, you want the wheels to end up with zero toe while rolling down the road, I like to spread the front of the wheels while setting the alighnment and set the toe to zero, thay seem to roll a lot easier when setting them this way, if you run the carb a tad lean to keep the plugs clean then richen it up to run it's fastest. Remove floor mats, glove box, contents, jack, spare tire, trunk mat all excess fuel (don't fill it for ballast, sloshing ballest does almost no good, if you need ballast bolt it in the trunk as close to the bumper and high as possible, if you can bolt it to the roof of the rea edge of the trunk even better), set rear drums for no drag, WD-40 on all the front end rubber bushings to loosen them up a little, make sure you leaf spring clamps are good and tight... If I think of any more I will post em up

Get all the oils hot and thin, and the water and intake as cold as possible.

I use to do this...made 0 change if the battery is up to full charge... use as much air pressure as you can in ALL of the tires... thinnest oil as possible plus 1 QT low... crank scraper if allowed

Thanks guys for the suggestions. It has a 904 trans and a spool equipped rear. I wish I could put some real tires on it and it still be legal. lol. I am going to pick up some 0 weight oil, and I have a few ideas on how to cool the car down between rounds. I need to get this carb straightened out still also, a/f last time out was around 10-11:1. I didn't realize that nitrogen is that much lighter and can make that much difference in the weight of the tires. I have a nitrogen tank and regulator at work.... 6-8 lbs of rotating weight would be nice to get off.
Keep them coming!

Also I picked up a 16v race battery, figure it is worth a try? Anybody gain anything switching from 12v to 16v?

Keep adding weight to the rear of the car and launch the car more aggressively. When the car slows down go to the weigh of you fastest pass. I think the 60's will improve enough to over come the cost of the extra weight.

The 0w oil didn't do anything but freak me out going down the track. The 16v battery was worth something. I am assuming the alternator not working had something to do with it, though it seems to even idle better. My homemade vacuum pump was worth something. Tuning the carb was worth something. Staging shallow made a huge difference. Making the rear brakes stop dragging I am sure helped. Lowered the front and rear of the car over 1 1/2". Took the suspension apart and re-greased everything, Re-did the alignment. Still couldnt launch the car higher than 1100rpm. Overall the car picked up almost a full 2 tenths and 2mph over its previous best. 60' stayed the same at it's best 1.68. This is the best air and track the car was ever run in, was great air, I think right at sea level, best previous was 1200ft. I think I picked up more than most of the guys? On an interesting note, the car picks up an even amount .1 in the 60' equalled exactly .1 in the quarter.
