What do I need to make this car a bracket car?
What do I need to make this car a bracket car? First off I know the 6 speed has to go. Can these cars be made to run consistantly enough to bracket race? I know my car can vary .3-.4 depending on the DA. What do I need to do to turn it into a bracket car?
I'm sticking with the nitrous on this car but what can be done tuning wise to help it be consistant?
My mind is made up on turning it into a bracket car.

Suspension and tuning is where the consistancy is at. Go overkill on the suspension wherever you can, DA shocks, adjustable everything. There are a lot of little things you can do with the tune to gain consistancy. I run index classes and the car won't vary more than .03-.04 all weekend so it can definitely be done.

I know that tire psi, bottle pressure, launch and other factors go into a consitant run but I know with the setup I have now it's not consistant even though the 60' times are.

I know you want to run n2o but thats part of the problem. Bracket racing is all about reaction time and running the number, it doesn't matter how fast your car is. Like zracer323 said get the susp. and tires working, then you can work on going faster. As a side note I went to E-town on 11-25-12 for the Imp. vs US and my time trials were 11:23am right lane, 1.613 60' 11.857et 112.56mph. 2 hrs. later (2:29pm) in the left lane, 1.599 60' 11.852et 112.49mph. But 1st round wasn't until 5:25 pm and it was 37 degrees, car spun bad and I was out. That's drag racing!!! Larry

Verdad Gallardo Well I have personally seen my car gain .50 in one day in e.t. as the da got better. I've heard of people getting a speed density tune and being more consistant. But personally I don't know if it is or not.

Anything past 60'. But really inconsistent after the 1/8th is worse. I don't know what I'll do after the tranny swap. It'll definitely help the 60'. Right now I'm 2.0 60' and around 122-125 mph in the 1/4. Times range from 12.40-12.05. It's just as inconsistent off the bottle just slower with the same 60'.
On the trans, skip the 4L60E and go straight to the 400. For what a Rossler 400 costs it's a no brainer. I wish I had gone that route back when I still had my Trans Am. I went from a 6 speed to a 4L60E. Should have got the manual valve body 400 and be done with it. If you aren't planning on going on long trips on the interstate, you won't miss the overdrive.

Just curious I have a stock 4L60E w/TCI 3000
Why is the 400 better? Cant the 4L60E be a consistent. Why cant you just leave it in drive and wouldn't the computer shift it the same every run?
I would like mine to be more predictable but would hate to switch transmissions and not see an improvement worth the time and money.
?????
Thanks

The 400 is lighter and stronger. I used to change setups often and it was a pain in the butt having to go to someone to change my shift points and stuff every time I wanted to try something different. It's cheaper too, and converters for them are generally cheaper. Probably not much difference if any in consistency.
The 400 is much stronger and more reliable and like stated above is much lighter. The only bad thing about it for me is it's a 3 speed tranny.
Like I said above. N2O will be on the car and as long as I keep the same pressures during each run and make sure I'm purged the same each time the nitrous shouldn't affect the consistancy of the car. There are plenty of bracket racers running gas right now.
That's what I'm trying to find out. What will I need for the car to make it consistant enough to bracket race it? Any nitrous controllers, different tuning, delay box, trans brake or any other modules that are adjustable to the conditions?

N20 is not easy to be consistant.
The 4L60 can be built to be consistant, I use to run a 10.50 class and hit it all the time.
My local class racer runs a T400 and his car is SD tuned. On top of that he has a pressure regulator so he can do small adjustments at the track to make up for DA. He's won the class 2 years and 2nd the other over 100 racers. He calls me bitching if the car is off .006 on his dial. LOL
