A little extra!

[89lxinwky]

I ran 8.38@83.6 in the 1/8th last time out on a hot humid night. What other inexpensive little things can I do to drop a few tenths down to the 7.99 range? I'm building a house right now so I don't have much time or money to spend on the car for a little while. Last time I stripped most everything out of the car, spare tire, insulation, jack, etc. I played with the fuel pressure, timing, tire pressure, and ran without a belt the last run to get my best time. The car is hooking pretty decent for what I have(1.88-60') so traction is OK but it could be better. I'm thinking some good synthetic oil (Royal Purple), maybe rig up a flexible dryer hose/sheet metal for a shotty homemade ram air at the track and icing the intake between runs. Maybe relocate the battery to the rear. What about some fuel additive like Torco (spelling?)? I figure on a cool night this fall, I might gain a tenth or two with that alone, and if I could do a couple little things I might could do it. Any other suggestions?
Thanks
