advice on dual stage nitrous set up

[quick coupe]

my 10" tire notch (see sig pic), set up pretty close to a nitrous dr car. I have a fogger and will be installing a x-bar plate. plan on spraying around 450hp total. 3250 lb car currently has a c4 and wheelie bars but next time out it will have a glide and no wheelie bars. . car currently goes 8.60 @ 156 with a 1.23 60' time with .036 jets in the fogger on 28 x 10.5 mt's. this is a sbf with r heads. that 60' is at rt66 where the track is prepped to death. i am thinking to set it up to leave a little softer so it will be more consistent on worse tracks...i wont be at 66 for competition. would just like some advice on where to start....which system to activate first...and so on. thanks!

How do you pull timing out of your motor? Are you going to run a digital box or pull timing out via a 3 step?

if u have daly timers u can set the small one up first and set 2 system about 3sec later u dont wont them to both come on at same time or u will put it on the back bumper. and with that tire u wont to get on top of the tire as fast as u can.

PUT a GLIDE in it. with your weight, 1.80 low gear.

Ken,

I can show you how to take timing away using your 7531 box to kill some power when you come off the brake and then feed it back in over time.

PM me your digits if ya want or email your MSD tune-up file and I'll tweak it for you.

I help run the program on a friends Nova, it has a 540, 2 kits(plenum bars & fogger), weighs 3550#(no sh!t)28X10.5 tire, Stock suspension. We leave on a .087 jet in the plenum bars and 0.9 sec. in the fogger is stacked on it with a .033 jet. What I have done is have the car leave on the total timing the the system needs with the kits stacked. We would usually run 25 degrees with the plenum bars alone and 18 degrees with the systems stacked, so what I do is when the first kit is activated when the brake is released the ignition box pulls the timing down to 18 degrees, if all that makes sense and the car leaves on that!?!?!! The car has been 8.38 @ 165.2(still working on the 60's, but no wheel stands and the car is very predictable, but it wasn't befor, it liked to wheelie!!!!) The day that it went a 8.38, it also ran 2 8.39's and 1 8.40 that day; like I said the car is very predictable!!!!! Hope some of this info is benificial!

ooooooooooooooooooh yeah. I remember talking to you, but not about that. I can't for the life of me remember how you told me you were doing it.

Well, one thing I think is common knowledge is that a plate hits harder than a fogger will. ORRRRR, if you adjust the nitrous line length between the nitrous solenoid and the distribution block, you can control how hard your fogger will hit. If I were you, I'd run the plate out of the hole and take away timing and feed it back in over time. Then, I'd use the fogger for the second stage cuz it would hit softer and ease the transition. Don't want you to blow your tires off the car when stage two hits if the track is marginal.

Hmmmmm.....you could do a head swap and leave the C4 in the the car and be REN legal with the correct cam. That's if you're under 410 cubes, which I believe you are. YOu wouldn't be just tryin to pull one over on us would ya?
Can't remember if you're carb'd or not.....;)

Junkyard -

What type of controller are you using to bring the fogger in @ 0.9 sec?

Thanks,
