nitrous+gears+tires...prep for race day

[silvergt2001]

whats up everyone just a couple of Q's.....I'm going to the track next weekend with an LS1 buddy, and I want to be prepared.

I've raced at the 1/8th when I only had a CAI and I was running 9.30's.
Since then I've done all the mods listed in my sig, but I've never had a good set of drag slicks (aquiring tomorrow).

I just installed the nitrous kit with 125 jets and I'm a newbie at this stuff. Please feel free to give me some tips/pointers!!

I have NO idea how to properly set up the tune with the diablo and I would rather not blow my motor. What kind of timing and fuel trim settings are you guys running?? and no, I won't be buying a RWTD tune this week.
thanks for all the help.

i hope you have some extra money laying around for when the tranny goes. all the guys with 4r70w's that i know that spray them, the tranny doesn't last to long. that is why i haven't sprayed mine. i just cant afford the fix right now.

hmmmm.......I've always heard the 4r70's were tough except for the o/d band. I have ran with moderately increased line pressure for over a year, along with a giant trans cooler/no probs so far.

Ive sprayed the heck out of mine with not a hiccup from the tranny. Shes holding up beautifully. With an auto the driveline is set. It doesnt bang hard like a static driveline with a manual when you shift.

I am running one step colder plugs and stock timing. Drive around the puddle. I open my door and backup till Im lined up with the front edge of the puddle then I pull forward just a bit and hold the brake while I do a burnout. Youre not John Force. Dont overdo it. After that line up with your foot on the brake and the other on the gas till your rpms are ~2200. When the tree goes green stomp it. I spray out of the hole. Ive got my best times using this method.

eh...they say the 3650 is only rated to handle 350tq...i put almost 500 to it daily and it takes it and asks for more..
