DNF!!!! haha I had a great time on friday test and tune, but as the real competition showed up on SAT, old blue got the willys and started acting up worse than on the way up there with wierd tranny shifting and starts. It started shifting down from overdrive to 3rd on its own. (overdrive button off).
I took the entire center console out in pits to access the Overdrive button on shift knob with DVM. Open, both positions. Cut leather off handle and scooped out the culprit. ( i needed a new one anyways, and i HAD to know what was going on.) Sure enough the wires inside up in handle one side had sheared off leaving an open. Also, the car was taking off in 2nd gear sometimes and others third gear bogging after nice crisp burnout. So i didn't get to run in the end all competition at all, pulling out of competition after only 2 runs on Sat and worring about the transmission.
So, i did what any other upset person would do. I went to the grand stand and ordered another cheese burger and jalapeno nachos. haha Seriously though, i did have a great time both days and met alot of other nice Lincoln Mark VIII guys and Maurader people in pits. Great folks and good times. i wish i could of stuck around for the after race party, but i wanted to drive home with straight head in daylight in case something went wrong with car. i don't make the best level headed decisions on Bud Light.
Babied it home running below 70MPH the whole way to FL. Yes it took me forever but now i know how the grannys feel when people blow by them at 80-90 plus MPH. hahah it's very humbling in Atlanta traffic hiding in middle lane on 85 south while traffic screams by on both sides.

Anyways, heres scans of my four best runs.
Baro was: 30.14
Humididity was: 64%

P.S. i need slicks..... lol

That's some impressive miles per hour to be in the 14s, IMHO.

FWIW, I don't think the O/D button would be causing any shift issues. You may have some issues with the MLPS or the tranny harness.
 
RE: Superheavyweight shootout results...No 13's !!!!! AGGRRR

Congrats on the runs you did make, and I'm glad you had a good time! Sorry I wasn't able to make it (yet again) this year.

And yes, I was pretty impressed to see MPH over 100 too.
 
RE: Superheavyweight shootout results...No 13's !!!!! AGGRRR

Thats exactly what i was thinking on way home, what could be causing the forced intermittant downshifts. I noticed driving with the entire center console in the trunk, that my shifter actually sits in the 2nd gear slot when in drive. Pushing it up to the regular drive slot where it would be next to the D, gave me neutral. Also (i never noticed before, do we have a sliding lit bar for the gear indicator? or just a bulb that lights up in each position for our shifters? cause mine just stays lit thats it. One color, no diferentiation of where the shifter actually is if somone were looking to see what gear they wanted to be in. No indication of what gear your'e in. I never noticed before and always just went with the feel of it without actually looking at the shifter position while backing out as long as i've owned this car. "Did that used to light up?" or never did?" Funny how you notice little things like that when it's broken. I'll know more tommorow when i go digging around for stuff in my driveway.
But now that you mention it, the shifter does require effort to push it and engage it into gear, like cable needs lube, but before it effortlessly glided into gear like velvet and securly clicked. Now i have to "make sure" its all way forward and engaged into park or it will pop out.
Yeah, i saw alot of Mauraders there and times in low to high 13's between 92MPH and 98MPH, and yours is a good example too. I just am not grasping the logic of how my mph is faster but its taking me longer to make pass. Is it im slow out of the hole because of traction and fast at the end? Or are their cars just more powerfull and do the whole shebang quicker and dont take that long to get up the speed before its over?
A side note: my rear end feels like it raises alot and gets squirrley twords end of track in the 1/8. But i really noticed it bad at the 1/4 mile my first time with the Mark. I had to be really light on the steering wheel. My first run i let off wayyy early and laughed at myself when i went through the time lights coasting on brakes. LOL I'm used to getting on the brakes hard after the 1/8.

Sierra3, what mods do you have? Where you spraying or were those runs NA? I think your tranny is the reason for your relatively bad et's compared to your MPH. Even with 2.3 60 foot times, with 100-101mph traps speeds you should be running a little bit quicker than 14.4-14.5.

NA 2001 SVT Cobra motor, 255 Walbro pump in tank, 90MM big air MAF,ART longtube headers with 2 1/2" duals into magnaflows with crossover, brand new Art Carr Extreme tranny with all hardened output shafts, forced tail lube, and 3200 stall. MMX driveshaft into FMS 4:10's Eaton posi, and stud kit. Stock mark 8 ignition coils and plugs 2 steps colder. FMS wires. SCT chip and dynotune. See attachment for printout. Not much more than that. Bridgestone 245 50-16's on all fours, no slicks yet.
My car weighed in at 3955 at Atlanta with 3/4 tank of gas and me in it on scales. I weigh about 160 last time i checked.
I think the biggest reason is i have no IMRC valves. The intake is built for a manual shifted Cobra mustang, not our heavy marks. So it stinks on low end where the mark intake makes up for it with the valves opening after 3000 RPM.

Ahhhh, that explains the high trap speeds for the ETs exhibited.

Thats my best guess as it does bog off the line. My original Mark 8 intake was so much crisper and snapped off the line. I am keeping an eye on the auction site for the bullet intake. Anyone know if it will fit the PI heads? That would also cure my air intake mounting problems as that one comes off at 45 degree angle instead of 90 and any aftermarket mustang cold air intake could be used.

RE: Superheavyweight shootout results...No 13's !!!!! AGGRRR

Are you flooring it off the line? The 01 Cobra motor with longtubes you are probably making 280hp at the wheels.
 
RE: Superheavyweight shootout results...No 13's !!!!! AGGRRR

yeah we dynoed it at 291RWHP just before i went up there. I tried both ways, punching it, which resulted in excessive wheelspin, and walking it out and then dropping the throttle.
Update, just had new MLPS switch put in today and yes my problems are cured. I still need to get the tranny shift points tweaked for around the town driving and on highway, but i'll hopefully have the dyno guy ride along with laptop and do it in the car.
After a barbecue dinner tonight with another dragracing friend, he seems to think that i need to go DOWN with the tourque convertor back to say 1200 or 1800 like in my originall tranny (just a high performance one.
I took him out in car and pulled it into 1st and slow launched, and then fast launched it to floor. It's slipping too much when its supposed to be locked into 1st gear. I'm beginning to believe i went too high with the torque convertor choice at 3200 myself. The car was really faster with the old tranny that is sitting on my front porch deck right now. It had the all stock mark 8 convertor. My car makes good power starting out at 2000 RPM all way to around 6000. The originall mark 8 engine didnt untill around 3000 RPM when the runners opened up, then it pulled crazy.

RE: Superheavyweight shootout results...No 13's !!!!! AGGRRR

Hmmm... that's an interesting observation. I would think with the IMRC deletes you would want a stall in the 3200rpm range. It's hard to figure out how to launch these cars at first but keep practicing and you should be able to get that 60 foot time down a lot and easily get into the 13's with the amount of power (101, 102mph) you are putting down. I'm very intrigued that you dynoed 291rwhp and trap around the same MPH as I do, slightly higher. I wonder how much horsepower i'm putting down to the wheels these days myself. Our racewights are almost the same I would imagine. I think the 3200rpm torque converter might skew the dyno a bit but by how much?
 
RE: Superheavyweight shootout results...No 13's !!!!! AGGRRR

Was the stall for the Cobra or the original Mark or a guesstimate of the Cobra motor in the Mark? Besides the stall speed, a converter can be too 'tight' or too 'loose' for the torque output of the motor vs. weight of the vehicle.

I recently rode in a turbo'd 5.0 that literally blew right through the converter in 1st and 2nd on WOT on an AOD. That same converter had been re-stalled specifically for the upgrade and previously had been 'tight' on the same motor. It was definitely going to have to come out and be reworked again.
 
RE: Superheavyweight shootout results...No 13's !!!!! AGGRRR

Hmmmm, I have no idea. It's the 9" one that comes with Art Carr best extreme tranny. I don't even know what to ask him for. It was said to be 3200 stall and i ordered it for the mark 8 tranny, so i hope he knows how much our cars really weigh compared to a mustang and set it up accordingly. I'm going over to my drag racing buddies muffler shop/garage today to show him the dyno run. I'll se what he says about the convertor.
 
RE: Superheavyweight shootout results...No 13's !!!!! AGGRRR

Well, the 3200 stall for the Mark VIII may have been right with a 290 FWTQ 4.6L but not necessarily so with the Cobra motor.
 
RE: Superheavyweight shootout results...No 13's !!!!! AGGRRR

Yeah this is a nice picture, i saved it. Thank you for looking out.
I have good news on old blue. Took it to a local shop here that does all the dragracing transmissions for different cars here. Was worried about the sprag getting slammed on way home with the shifting issues. They dropped the pan and checked the EPC and all line pressures or something to that effect and all checked out good. I was told that the chip wasn't commanding the car to use first gear at all. Thats when we removed the chip to tell again. (of course the car ran rough without the correct fuel ratio that was in chip.) But all gears worked, and when stopped at light in drive, it actually went all the way down into first. I then went over and had chip reflashed back to normal stock mark 8 settings and shift points and put the chip back in.
At Atlanta i was taking off in 2nd gear thinking it was 1st! The chip was locking out the 1st gear and starting it in 2nd or sometimes 3rd. Which explains the intermittant bog i was talking about. It still pulled hard so i assumed it was first. lol We didnt know because it felt normal and quickshifted quickly and smoothly so you couldnt count. The SCT chip was reflashed back to "original" stock configuration and i have first gear again. I left it at Lincoln Dealership to adjust the cable and make sure new MLPS switch he put in is all good.
The car Definately pulls alot harder in just the first three feet in back parking lot of Lincoln dealership after putting back in the chip, before we shut it down and parked it for the night till tommorow. I'll know more this weekend at test and tune as to what actually using 1st gear will gain. :eek:

It will be worthless without decent tires.

yeah i know, shopping now as we speak.
Ohh...When i went over there to get chip reflashed, there was a very clean sleeper trim 3rd gen Trans Am in there with over 400RWHP on the scales! I was just starring at the computer...lol You would never be able to tell if it was sitting on ground and you couldnt see all the subframe connectors and goodies underneath. Only clue was some MT Et streets on back of stock 5 star chrome rims. Too cool.

Yeah, you think the Blue Flame could use some chassis stiffening? :7 I think I may try unhooking the front swaybar next time at the track.

Get me some hi-res pics of your beast for the calendar project! :9

Tires? Might I suggest looking at some Hoosiers? }( After studying film from my last test and tune, I don't think there was ANY tire spin at the launch!

I would still keep that torque converter question open. Would maybe sending a copy of the dyno graph to the manufacturer help?
 
RE: Superheavyweight shootout results...No 13's !!!!! AGGRRR

Sierra, you should easily be in the 13's this weekend. Good luck...
