I saw a closed thread and thought i'd offer some friendly input.

I was pitted with sal this weekend at the track.

First thing you guys have to understand about competition is we all deep stage.

These trucks lose 1.5 tenths deep staging, i lose it, sal loses it, JL loses it. We actually had a big convo about it this weekend.

When Sal gets back, I think he'll post his slips. His 1/8th mile was incredible, even with the deep staging, on the big end, the truck was shutting down, we're pretty sure 1 or both pumps are going bad.

The nitrous safety switch kept shutting the nitrous system down.

He still ran 11.58's.

Even though it's a crappy track he normally runs on (as far as how its run), the track itself is an awesome hooking track and corrected elevation is awesome.

That is why some of the best times come from Cecil and E Town.

Just some info for the crazy's out there

Once sal gets back, we can compare the 1/8 miles from his 11.20 to the 1/8 miles this weekend, (keeping deep staging in mind)

 

Beef,

Well said...
Exactly right!!!

 

Beefcake- What do you mean these trucks lose 1.5 tenths by deep staging?

 

if i am running a pro tree, my truck will run say a 12.49, and i will cut a .700 to .720 light

in competition we are running a .500 pro tree and .7's will not cut it.

so, you "deep" stage. for those that do not know what deep staging is,

you turn on one light, you roll forward and turn on the second light, now you are "staged", if you roll forward more, you will turn out the top light, you are now "deep staged"

when i deep stage running my race program, i will run 12.6's, but i will be cutting .520 to 570 lights

i pick up .15 roughly in my lights, but i lose .15 off my et, these trucks lose almost exactly in total et, what they pick up in r/t (reaction time)

in "bracket racing", et doesn't matter, consistency and lights do!

 

Ummmmm, why not cut a better light? LOL

 

Beefcake, the .5 pro tree that you are refering to is all three lights coming on at once, then green?

I can see why you need to deep stage. The trucks just won't react that fast.

 

Someone please explain this to me better!

How does staging matter to your E.T.?

I thought your time(E.T.) doesn't start until your truck actually moves (breaks the beams)?

Jason

 

ok picture this.... your tire is from |--------------------| to here if you stage with the beam just breaking the lights |------------------Beam| you will "roll out" before breaking the beam BUT if you stage with the beam at the back of the tire|Beam--------------| then your your ET will reflect the differance.......Get it? ok so I suck at explaining... anyone else wanna try


Johnie

 

Jason, If you deep stage, the truck will only roll a very short distance before breaking the beams, and starting the clocks. This will reduce your reaction time, as the truck has less distance to travel before it does break the beams.

This will not allow your truck to build any speed before breaking the beams and starting the clocks.

Conversly, if you shallow stage, the truck can actually accelerate a short distance (6-8"- depending on tire diameter) before the before the clocks start. You have actually accelerated slightly before leaving the stage beams. It's like having a 6" running start. I realize it doesn't see like much, but it is measurable.

You will get better ET by shallow staging. You will generally have a longer reaction time though.

 

Thanks Jay, I understand where your coming from, but do you think its a .15 difference like beefcake is saying?

Jason

 

definately .15, i've tested it many times

i was over talking to JL about et's (believe it or not, everyone gets along for the most part, even the big tuners lol)

anyway, we were talking about the deep stagin and i started to say to jl that I always lose ... and he jumps in with .15 and i said exactly!

try it out

if it was a sportsman tree, i probably would not deep stage as you see the lights coming, it makes a big difference on the pro tree.

CC, anytime you wanna go against me on the tree, i'm up for it

 

Beef is the man ! I think every one has a nicer tone because of those Gun's you got lol ! But very well said ! And all of this is Nutz to me all i wory about is moveing up till i stage and wate for the green.... lol im not a pro at all !!! i have only ran my truck 4 time's with the ranger and 2 times with the Lighting and i keep getting better just got to go on a week day and practice ! what can i say ill get better ! lol

 

I just can't say. I've never run on a pro tree. .15 is actually a pretty small amount.

I would guess that the combination of human reaction + truck reaction time could add up to well over .500 seconds.

I think the major difference isn't in the human reactions, it is because the truck are so massive. They will not accelerate as quickly, so the vehicle reaction time will suffer considerably.

If you can get them 6-8" closer to starting the clocks, it might make that big a difference, due to the slow vehicle reaction time.

It would be interesting to try next time I'm at the track. You can measure my reaction times with an hourglass. I could use that .15 myself.

 

in my cobra it was more like a .05 diff.

but the car was lighter and was packing over 200 more HP.

When I'm going for E.T., i just inch off the brakes to barely turn the 2nd light on,

in competition i always deep stage, not too much though, cuz I am quick off the line!

 

Corner Carver,

I could use some instruction of the pro tree.

Does anyone know the time from the Second Staging light on until the Yellows?
