I was wondering that my self, It seems when i first leave somewhere after my truck sits, the turbo actually is kinda quiet and it seems like its not doing a lot till you come to a stop , then take off again and THEN , the turbo comes to life, must be heat related huh? I was wondering when i go to the track if just doing a good long burnout would be helpful for the turbo cuz after sitting it doesnt work as good as when you drive it down the road and get it warm, then its ON&#33;&#33; Any other STS guys notice this?
HELL YEAH, Charlotte and JR.&#33;&#33;&#33;&#33; I just got excited as Kurt Bush almost wrecked&#33;&#33;&#33; ( ASSHAT&#33 The track looks slick but smooth, no more Humpy bumps&#33;

Hey Alton, is this time RE-Levigation? LOL&#33; Cant leave well enough alone. JR.&#39;s house&#33;&#33;&#33;&#33;

Good analogies - I guess one of my questions would be how would you go about actually matching a stall to a cam? Are there any proven methods or "formulas"?

Obviously the cam mainly gives the hp and the stall gets you there quicker, so with all of the different stalls, I would assume you would want the one that gets you there the quickest for your best 1/4 mile times.

An easy, general way would be to pick a converter that stalls just below or right at the trucks torque curve. Say your torque shoots up to 350tq at 3200rpms, I&#39;d get a 3000rpm stall converter in there.
Just one way.

Hey, if JR and Harvick cant get it done Tony can, he dont take no shit and keeps the bowties up front&#33;&#33; BUT Any way Alton or Allen if your here, What was the best way to get the heat in the turbo after just sitting, Is a good burnout enough?

the only thing you can do at that point is a good burnout but the best thing to do is hot lap it if possible....

During bracket racing, reaction time has everything to do with winning. The slower your reaction time when bracket racing, the slower your overall time on the sheet.
If you run a 13.0sec 1/4 mile and dial in at a 12.99 but your reaction time is .600, I run a 15.00sec with a reaction time is 14.99 and have a reaction time of .500, I win.
They add your reaction time to your 1/4 mile time during competition only.

So guys, when you&#39;re at the track, and you&#39;re practicing on how to launch, forget about the green light, let it set and take your time, don&#39;t worry about the reaction time.

Man I don&#39;t know where you guys are racing at but up here where I&#39;m from they absolutely positively do not add your reaction time to your E.T. If I run a 8.00 1/8 mile it doesn&#39;t matter if I sit at the light for a solid minute my E.T. will still be an 8.00 on my time slip, competition run or time only. Granted I will probably lose the race due to the fact that I had a 1 min. reaction time (unless my competitor has an even slower reaction). In actuallity it took me 1 min. and 8.00 sec. from the time the green light came on to when I crossed the timing traps, but my E.T. is still going to be 8.00. Reaction time is very crucial to winning a race but they do not add it to your E.T. on the time slip or anywhere else. Like I said before the timer doesn&#39;t start until you break the staging beams.

You win By .100 of a second. ET= Elapsed Time = Time from point A to B.
RT= Reation Time = Time it take to activate ET timer.

Because ET was the same for both cars you get the win lite based on Reactime to start ET timer.
Time on Board is only ET. Win Light= to first one to the finishline

I think the point is dont let the game of drag racing get confused with a run at the track to see how fast your truck is.

I usually let the engine sit while in the staging lanes. that will heat up the turbo. I do turn my fans on and engine, iat and trans temps come down, but the turbo gets hot. i haven&#39;t tried hot lapping it.
last run at the track i did a retune, it was getting faster each time, so i&#39;ll make sure to have a good weeks worth of driving before i drag it again.

cool, so it is a " heat" issue when first taking off from a cooling period.

This will answer my question and clear things up on how you&#39;re explaining it,

Question:

We both are bracket racing
Your dial in time: 13.00
Your actual run: 13.00
Your reaction time: .503 (based on a perfect .500 light)

My dial in time: 13.00
My actual run : 13.00
My reaction time: .500

Who wins the bracket race?

thanks,
allen
