 Subject: 1/4 times???

Message:
I just got back from the track and the truck is completely stock except for a airaid and crappy duals, its a 98 4x4 EC sport 5.2L. first run 18.646 @ 74.31mph w/a .497 light and a 2.811 60ft time, and my third run with the tail down and launching at 1300 I had a 18.6 @75.25 w/a .423 light and 2.842 60FT time. This is also at elevation of 5,800ft?. Are these times good for the truck and elevation? I wanted to run befor I put any parts on it. What can I expect from a 360intake, 52mm t-body, electric fan, hypertech programmer, crank shaft pully, gibson single side cat back, and full amsoil everywhere and a tune with 3923 autolites? Any guess would be great I cant wait to put all this stuff on but I dont know if I am going to do it all at once.. Well thanks for the help!

5800 feet! Holy smokes, where do you live? Well I've heard at 2400 feet at one popular track you subtract anywhere from .5 to a full second. Yours is definitely more. As a point of reference my 99 V6 club cab truck ran 17.6 with only a TB and different exhaust at 300 feet elevation. The air is so thin where you are you are starving that engine.

2.8 60' time....wow..
Are you just sitting there smoking the tires for about 2 seconds?
Your 60' times should be lower, around the 2.3 second range with stock tires.

On the NHRA Pages they have the calculations for elevation. Mine at 4,900 feet (Pueblo Motor Speedway, CO) is ET times .9393 = Sealevel conversion, i.e. mine, 15.6@88 x .9393 = 14.65@93.68. (This is pretty darn correct cause I have run 14.51@96 in San Antonio, TX 600') This chart lists all the tracks and there correction factors.
NHRA Correction Charts for Altitude
For Your correction use the bottom chart. You said 5,800', that would be Denver/Bandemere Speedway. So the correction would be 18.6@75.25 x .9276 = 17.25@81.06. Pretty close for a stock 4x4.

My truck a 2002 quad cab 4X4 4.7 3.55 gears with 350 miles on it brand new at 1000 foot elevation ran 16.54 to 16.75 at 81 to 83 MPH 2.35 60 foot times, I power braked it to 1600 RPMs, above that it spun the stock goodyears, so Higher elevation does make a difference for slower ETs and much less MPHs

Well your right its Bandemere speedway, and I was launching at 1300 to 1500 with no tire spin at all I think, they put down that track coating that rubber realy sticks to. What am I doing wrong, should I be launching at a higher rpm? Or is all this close to the normal? Thanks for the input so far!!
