That car has way more in it. No way thats all shes got.

Hes got a lot less weight than me, better gears, 4V heads, bolt-ons, more exhaust and I trap the same. Hes got way more in it something needs to be figured out.

All i've got is a stock 2V with a KB 2.1L on it and mid pipe + catback. And i'm heavy as a pig compared to him.

And i've got a boost leak to boot.

Once again, since no one reads the entire thread..... Numidia is the SLOWEST track in division one. EVERYONE will have slower trap speeds and slower ETs here, the track has the highest elevation in d1 and also is on a slight uphill incline. If you race numidia, and then race cecil county, atco, or englishtown you will have on average .2 to .3 faster ets and about 4-8 mph faster. Everytime someone posts times from Numidia the first thing people say is the trap speeds low, its not the car its the track. To put things in persective boolt on 2vs with gears will trap 85-90mph here.

sounds like you need some good ol' DA correction, anywhere from 11.9@115 to 12.1@113. if he ran on 6-22. elevation only correction is 12.2@112.

I read the entire thread. I just dont bow down to the DA gods like you do. Have the gun run at one of the other said tracks and we'll get this figured out pretty quickly.

Density Altitude. Air density changes based on temperature, humidity, elevation, barometric pressure, so you put it in a formula and determine what it is compared to the International Standard Atmosphere. It's used a lot in aviation, and serious bracket racers always calculate the DA to adjust their ETs.

this site has the math of it:

this site has the easy calculator

http://www.dragtimes.com/da-density-...calculator.php

once you start dealing with boost you reduce the amount of correction you get, there is a formula to use, i posted it awhile back, i'd have to look it up, but you have to figure out the air density and subtract your boost from that and divide it by the ISA density or something like that. for 10 psi at that relatively low DA you'll probably get somewhere around 1/2 correction, at 20 psi 1/3 and 30+ 1/4.. these are just general numbers I'd have to look it all up and calculate it out to get within a .1 or .2 of what it would likely run with good weather/low elevation.

Its just the way it is at high elevation track like numidia, no ones bowing down to anything your saying his car has more in it because u don't know how to take in account the factors of drag racing , track elevation etc.there is no "figuring it out" when the we already know the issue. You see a trap speed and your jumping and saying its not running right, its got more, blah blah blah. EVERYONES trap speed and ets are slower at this track not just his, this is not beep 3 times on the highway and punch it, you need to learn the basics before throwing out comments like that.

Why go there and post up times if the track is that horrid?



All times are GMT -5. The time now is 10:35 AM.
