I think I'm finally ready for my 11's

Since the beginning of the modding stage, I had 2 goals:
1) Run 12's on motor/street trim
2) Run 11's whatever way

I ran 12's everytime I hit the track last summer with the new combo. But had my share of problems. This happened at different times:
*clutch unadjustable
*fuel gauge giving me bad readings so I was screwing with the false pressure all the time
*differential rebuild ---> one wheel peel
*rocker arm got loose and pushrod cracked the vc

Everytime I was trying the nitrous ( 2 different days) nothing was happening. Finally discovered last week that it was bad fuel safety pressure switch that was causing it not to work. Since last year, I went from stock setup 70mm tb and air filter in engine bay to a Holley 75mm and "true" cai into the fender. Got a new Walbro 255lph fuel pump, driveshaft loop, 31 spline axles and carrier.

On Saturday, it is Mustang Day at the local track (crappy). This might be the last time I go to the track cause the stang is for sale and who knows when I'll sell it. I'm going with my 15x10 Prostars with ET Drags, and my skinnies. I've never tried slicks before. I was very confortable with the Dr's. Was getting 1.7's all day long and a best of 1.66 60ft with the 275's. Now I'm not sure how I'll do with the slicks.

I will run on motor first to see what I run. Have no clue how this is gonna turn out..Might even run 13's now, or maybe mid 12's with the new parts..Who knows ? But since the nitrous kit is working, I'm sure gonna use it. I'll start with the 100shot to see where it puts me. Not affraid to go 125 either. 150shot is still in my mind and is a possibility.

Why do we have to retard timing, regap plugs, run colder plugs for nitrous ? This is a good power loss right there. I usually run naturally aspirated with the timing very agressive, autolite 24's plugged at .052. Now for the juice, I have the timing backed up a few degrees from STOCK timing not my agressive timing, autolite 23's gapped at .035. You can definately see the loss of power. Could I still be running my autolite 24's , but gapped at .035 with STOCK timing ? I'm sure I'd be fine.

I wanna drop the clutch on slicks at around 4500-5000rpm on the juice and see what happens

If everything works out, I should be seeing my first 11 second timeslip If not, it will be the unexperience of the driver with the slicks that failed, not the car.

Sorry for the long post folks...Just very anxious..

Did you run those 15x10 with the stock axles w/stock studs are did you get longer ones???

I was running 15x8 with 275/50/15 BFG Dr's last year on stock rearend and axles on stock studs. Now I have the 15x10 prostars with the new 31spline package and the ARP longer studs.

if so why?

Yeah I'm selling the stang after 3 years of owning it. I have school debts, personal loan, all kind of credit card debts. I need to pay all this ASAP so I can move out with my gf on July 1st.

I will miss the car for sure. I still love it but I will love my next one even more.

No I didnt get my 11's. Here's what happened.

Ok so I get there around 10h30 to change tires and let the car cool down. Well whatever that is when its 95*Fahrenheit without humidity.. And I usually ice the upper intake when its that hot but I totally forgot it yesterday. Didnt bring the ziplock bags. I decide to go do my first run on motor only. I have my slicks at 13psi. I'm very nervous at this point. Really have no clue how it's gonna be with the slicks. Drop the clutch at 5000rpm and it hooks like a mofo. Hooks too much even that it makes me bug kinda. Was 1.67 60ft for that one. EASY shifting and got 12.82@106. The car with the slicks was totally stable. That was a huge relief. And again, lifts the driver wheel off the ground. Remember that my previous best is 12.801@108mph. So I didnt think much of it. Do it again but with 2 more psi of fuel pressure (42psi vacuum off) and 1 less psi in slicks. Dropped again at 5000 but this time bugged me way too much and got 12.9 Next run a drop the clutch at 5600-5700 and hooked like crazy and got a 1.61 60ft and got 12.76@106mph. New best. I was happy but I feel like I dont know what I'm doing up there with the slicks. I dont think I have enough gear for the slicks on motor. There were also a bunch of ricers spreading water on the track with the fwd cars. I did a couple more passes but nothing that interesting. So if I did a 12.7 with that weather and first time out with the slicks, I'm sure if I go again I'll see 12.5's or so.

Now the NITROUS runs..

Changed the sparkplugs and timing. Lower the slick pressure to 12psi. I had the same feelings as before. VERY nervous now to launch the car on the 100shot, dropping the clutch at 4500rpm. So I do the burnout and approch the staging line. It is about 8h45pm and there's a HUGE crowd of people all over around the track and staging lanes. Just before I light up the first light, I purge. Then I hear the crowd go crazy and starting cheering. That was a pretty good feeling. Which didnt last very long...

I drop the clutch at 4500rpm and a HUGE boost of power make me almost hit the left wall (im on the left lane) so I let go the throttle. Shift in 2nd the car breaks loose BIG time again. Almost hits the wall again. I complety let go the throttle again. Shift in 3rd the car breaks loose again. Let go the throttle. Shifts in 4th the car breaks a little loose but I keep it on a little. Apparently the crowd was like..OH !....AH!...Whoa!...My friend has that run on his digicam and if I can I'll post it for sure. You'll see for yourself how crazy it was. I ended up with a crappy time ..Not surprised since I couldnt get on it at all. 12.9@something but I still won that race

Now I was pumped. The power/torque was amazing. Its more the torque though. I'm thinking more than 400hp@the wheels and 510-530 pounds of torque@the wheels. So my friend says to put more air in the slicks cause I was breaking loose way too much. I decide to put it to 15psi. I go in the lanes and have to push the car cause theres a big line up there. So it's now my turn. Do my burnout, arm nitrous and purge. I go to stage the car. As I'm making the rpm climb up to launch I feel and hear something very weird. The throttle sticks ! I'm like wtf ? Un-arm the system and arm it again. Proceed to rev the engine to launch the car. Same story. I knew something was wrong and decided to back off the lane and not run. VERY good decision. The sound was different when the throttle was sticking..You know why ? It was the WOT switch of the nitrous that was sticking under my pedal so the nitrous was ACTIVATED and spraying while I was above 3000rpm and trying to rev it up to launch properly !! I could of blown easily my engine right there. Thank God. So I called it a quit for the night.

I just fixed the sticking problem and it will NEVER happen again. I'm sure 2 more runs on the juice and I would of had my precious times...Next time.

Like I said I'll post pics as soon as I get them and vids also if I can.

Not sure about low 11's but we'll see. Just need to find the right pressure for the slicks and I'm in.
