Track Last weekend... Truck Seems Slow

Monster Stroke · Jun 20, 2012

Ok guys I have my 08 ec/sb with a 4" lift and 35's.

Full exhaust, EGR blocker plates, Intake and IDP Extreme X Tune.

Only ran a 13.5... Everytime!!

I ran a total of 5 runs and they were all 13.4-13.7 with a 1.8xx 60' everytime.

I don't get it? I was under the impression it'd be a mid-high 12?

It didn't matter how hard I launched it, it was the same everytime....

And that was 4wd launch.

What was your tire pressure, and did you shave any weight off of your truck prior to racing?

Monster Stroke · Jun 20, 2012

I dropped the tires to 45 all around. And I didn't shave any weight but it's only a extended cab short bed with half a tank of fuel lol

Oh and trap speed was 98mph everytime as well...

Honestly not that far off for your altitude. Would be 12's at sea level.

extreme3807 · Jun 20, 2012

Bump your pressure down quite a bit. My ec/sb weighed in at 7600 before i put it on a diet with half a tank as well

Might seem weird but Ive been told before you run a truck unhook your batteries completly for 10 min or so..

Spatel23 · Jun 20, 2012

LOL

no

Ouch · Jun 20, 2012

no to unhook the battery?

08BIGRIG · Jun 20, 2012

Do not unhook your batteries!!! Just drop your tire pressure a bit more around 30-35

This + altitude + not race weight + to much tire pressure + no trac bars

Ouch · Jun 21, 2012

Something with the computer gets used to how you drive then when they get unhooked it resets itself.. No clue if it does anything but who knows.. whats it going to hurt..

My truck does seem a lot faster when I first load a new tune and then it seems like it fades out a little the more I drive it. I understand where your coming from

Makes sense to me but I dont know much..

^^ that. what is the altitude there? Get the spare tire, tailgate, maybe back seats? whatever random useless stuff out of the truck. Are they 35" mud terrains? Trac bars will def. help get that 60' down to 1.6.

LovinPSDs · Jun 21, 2012

When you start talking about 8K lbs, lifted and additional rotating mass it's hard to complain about mid 13s. Everyone knows the difference between a 14.5 to a 13.5 to a 12.5 is exponential, so at these speeds the small things start adding up...

put some Toyo proxys on your stock rims, traction bars and drop some weight! I bet it goes down.. what about the X-Race also? did you ever run it?

Question, how do 60' foot times equate to trap times.. I mean going from a 1.8 to a 1.6 doesn't mean 13.5 to 13.3 does it? 60' times are the most important part of the entire race right? I'm not much of a drag racer..

If I remember right altitude is around 4500 ft.

That doesn't sound like to bad of a time for all you have on and altitude..

Deff don't un hook the batteries. Your trans wouldn't have time to learn and would throw a **** fit.. LOL

pog · Jun 21, 2012

tunes feel strongest when you reload them. ive heard of people reloading the tune before they head to the track. that way it has a few miles to go through the gears. i personally wouldnt want to load it at the track.

Monster Stroke · Jun 21, 2012

Altitude at the track is 5,300ft. DA for that time and day was 7,300ft.

I have a set of trac bars for it just haven't installed them yet. And I do have the stock rims still... Thought about putting some Nitto 420's on them and then the trac bars and see what it'll do... Haven't ran the X race tune because the only one I bought was the Extreme X one.

But I decided I'm gonna leave it as is just through the 30th of this month and enter the bracket racing one instead of heads up. I mean it ran within 3/100ths of a second every time!! If that's not enough to win the thousand dollars I don't know what is lol
