i ran a 15.2 @ 87 mph on a odometer 1/4 mile. 1986 z28 tpi auto with firmer shift bands

conditions: cloudy, moderate humidty, 43*, no burnout, cold pavement.

spun the first 15 feet or so, even on an easy launch. also had the windows down.

mods: no muffler, cut out air boxes, 255/60 tires rear, bosch double platinum plugs, new wires, cap, rotor, a/c and air belts off, descreened MAF, 180* thermostat, tb coolant bypass.

 

that's very respectable for a TPI5.0 car. there was a 5.7TPI car (bone stock) running 9.8's (1/8th) which is about a 15.2 +/-. , so your running right there with the 5.7 cars

 

84 carbed 305 with edelbrock egr intake, Edelbrock TES, flowmaster muffler, Accell coil, AH metering rods with a G hanger.
15.5 dial in at the drag strip. Lot of wheel spin (it was a peg leg at the time). I don't remember the speed but It was just down to me and a 69 Chevelle left in the eliminations and he had the same dial in time so there was no handy cap. I was far enough ahead of him before the line I was on the brakes while crossing it and did not break out of my time and beat him. I got me a trophy!

 

what were your short times?

 

man, im pretty excited now about the upgrades i plan on getting as i know for sure they will get me into mid 14's for sure.

headers, y-pipe, race muffler for a cat, coil, air foil, alum. rad, and some other things (cant remember em), and im thinking a set of short height (14") slicks will get me into low 14's on 2.73 gears.

 

That is a good time, let us know when you hit the 14's, have you tried with DR's yet?

 

i havent gotten to a track. im sure i'd run 15 flat on a prepped track. im gonna get a set of track only slicks. theyre meant for imports, because i am using a set of 14" rims from a berlinetta. 8 inch wide slicks, but i think are 22" tall. should effecitvely reduce the gearing, but the back end is gonna sit so low

 

Those probably wont help with the traction that much.

 

they would as theyre softer than the tires i have. plus, i dont want to ruin the tires i have by racing and not hooking up, and the constant warm up burnouts. i know id be able to launch harder and hook up, which may shave a tenth or 2 off the et
