Mark Huckstorf from Huckstorf Diesel has organized (http://dieselplace.com/forum/showpost.php?p=1628110&postcount=21) the ultimate bracket racing season this year. 8 races with the winner getting a grand for winning each event. There is a points system and the points winner at the end of the year gets 3 grand in prize money. I want to know how I should set the truck up to be as consistent as possible? I'd like to win some this this big money once this year, so I need your help!!! I don't believe there are any ET limits here, so I'm hoping to dial it in around 11.80's if at all possible. Any tips or tricks to making a consistent setup are appreciated.

Call me for help on this. Too much to list

Biggest thing is get a racing log book(summit/jegs) and a way to measure wind/alt./etc. Put as much info into the log book on each and every run. You will see patterns and can get repeatable results even with different temps/weather/wind. It's hard on the ego to back down power, but it will help with consistency. Practice on the tree. Don't red light and give yourself a bit of room on your dial-in. Amazing how many races can be won just by not red lighting or breaking out.

Take all that crap off your truck and run 15's!:D

It worked for me.;)

a stock truck/car is the best for "no box" bracket racing

I'd have to respectfully disagree on this one.
1. The slower car leaves the line first. If there are two red lights the slower car loses.
2. Second with a faster car, it leaves you a chance to "fender" the opponent.

I like to be the fastest in my class, usually doesn't happen though in the classes I race.

I know I was the slowest one out there last year... I think it may have played with some of them cause they had to sit there while I was already gone... I did win a few cause my opponent got a red light cause they just couldn't stand the wait.

I would agree with you IdahoRob, it is much harder to fender someone with the slower truck... I lost a couple by letting out of it on the big end to avoid a possible break out... Now I just stay in it and hope the other lane breaks out more.

Racing against other diesel trucks I think a stock Duramax with a small tune doing a soft no boost 4wd launch would be very consistant and very reliable. Last year at Indy a Uhaul rental truck won the bracket class.

Set the EFI dsp2 up to have one side with a rev limiter. Stage on that tune and then have your "race" tune on the other side!;)

I've had mixed results using the rpm limiter. Might of just been my set-up, but wasn't as consistant as you'd think. My 60's could vary from 1.78 to 1.83 using the limiter, which equaled .07-,08 on the big end(= a loss). I would watch the logs, and seemed the fueling would go up and down while on the limiter, just depended when I launched if it was up or down at the time, which accounted for the varied results.

That does bring up a problem for the fast trucks. It's very hard to do your same routine of building boost, staging, and holding boost. Hard on the truck and hard to have it run consistant when you're waiting at the start with the truck at boost and having the converter and intercooler getting hot as hades for 5 sec. That does through me off, and I lost in a diesel event final, last year, for just that reason. Good point.

Maybe limit the boost and the fueling then?

I am proof that this statement is true. In fact, I was launching in 2wd for most of the season.... I think it is a simple fact of having less variables that will effect your consistency. I averaged .045 R/T over 15 races. The 60's were pretty consistent at 2.1X

BTW... That U-haul didn't win, the rain did;) I had him in my sights!!:D
