Instead of intake and longtubes I may be looking at clutch and slicks.  Take away to two things holding me back the most and then I can continue to tweak the third thing...driver mod.

SLOW night last night, track was packed out and I was stuck in the 8.1x range at 91 mph.  Only got 4 runs all night and I stayed aaalllll night.  Despite all that I was the quickest Coyote powered car, Quickest Mustang (in the street class, I was 2nd quickest overall to a turbo LS powered Coupe) and was the 2nd quickest newer "Pony Car" to a Hellcat, 3rd was an 07-09 GT500 that broke during eliminations.  I was shocked to hear I made the Quick 8...as #8 lol.  I stuck around to try and get a quicker pass in cooler weather and decided to run the Quick 8 for that pass.  I dialed in an 8.07 hoping to break out for fun but ended up running an 8.17.  Guy next to me edged me out by .0502 to eliminate me.  Slow night at the track but was still a fun one.

That car is impressive for so little mods. :yes:

Congrats! :up:

My RAI is what's screwing me.

If I can't get a good tune, I might toss it for the original style CAI, and then attempt to tune again.

Im beyond impressed and beyond pleased.  Quick despite being a bit...heavy.  Oh...and I still dont feel like I deserve this car.  

Most cold air intakes dont do much, especially without a tune but if you have one that screws with the MAF signal or causes un-necessary turbulance then ditch it quick.  There are so many out on the market right now that are proven to work for both of these cars, find one that most people like and then sell the one you have to help cover the difference!

This will be the third place Ive posted this but I want to put it in here so I can find it in the future if needed.  New best 60ft, ET and MPH last night, despite it being hot and the DA not being all that great (about 2262 per dragtimes).  I cant wait to see what it can do with a good 60 and some good air!!!!

No problem.  I saw the 8.06 too, but didn't get a video.  I knew you were going to be excited when I saw that 7.95.  Just think what it might do with some better track prep and good air a bowling green.

For comparison, I went a best of 7.76 with 91.66 mph and 7.64 with 92.4mph.  I bet with great fall air and traction you could run a high 7.6 which is an 11.8x.  That would be pretty  spectacular for an NA basically stock car.

Wheel hop city last night.  Cooler air tho, but only managed an 8.09 @ 91.43 w/ 2.04 60ft and then followed it up with an 8.03 @ 91.80 w/ 1.97 60ft.  Both runs I would spin right after the clutch was fully let out and I got the throttle to the floor and then the 1-2 shift was doomed every run.  They said it had rained earlier and the track looked like a river so maybe that was part of it who knows.

Its too bad they are pulling such a heavy cart!!!!!!!!

That's why I sometimes wish I'd kept the 97 GT and Coyote swapped. That car was light compared to today's hotrods. 

But the luxuries and all kind of make up for it.

I really was tired of the leg-press clutch in traffic.

Drive my 66 and the 97 woulda felt like an automatic to the ole left leg!  After driving it all day last Sat and hopping into the GT I nearly put the pedal thru the floor.  I will agree tho, the GT is smooth, quiet (until you unleash hell) smells good, SAFE, handles great and performs great.  None of which the 66 does at all LOL so Im ok with it being a porker but the Coyote + small/light car combo HAS to be a hell of a ride.

OH, there was a NASTY purple SN95 at the Hill last night, figured you woulda loved it had you seen it!

I had the FRPP HD clutch kit they used to call the King Cobra HD clutch kit.

As the Teflon lining wears out in the clutch cable, it gets worse and worse, too. When they break, you get to drive home in 2nd gear. Taking off from stop signs and red lights is real interesting with no clutch cable. Ask me how I know. :lol:

That said, I'd kept the old 97 GT for a project like that, but I don't have a garage (live in a 1,700 sq ft condo). So the weather would just beat on it until it looked ghetto. You just can't leave a car sitting out in TN and not drive it much because the humidity and all is tough on them.

Yeah...seriously next time your in the Boro, come try out the 66's clutch.  Itll make the King Cobra clutch feel like my 93 Escort's.  Im not saying this to brag...more to...whine LOL.  I hate it in traffic.  Driving the GT last year in Shade's traffic was a DRREEEEEEEEEAAAAAAAAAAAAAAAAMMMMMMMMMM compared to the 66.  Now with the little on on the way, unless Kathleen can ride with Spike's wife in a newer car, we might be taking the GT again and as much as it bums me out to think about that...the ole left leg is silently cheering.  Im gonna talk to the guys at TN Clutch one day and see if they can help me source a lighter pressure plate that will still handle the power.  I got to try out a couple of the other 6 banger cars clutches at the show, an original 3 finger and a newer multifinger like mine but for a Fairmont rather than performance minded and they both were smooth and light.  Mine is very tough and has a very noticeable engagement "sweet spot".  Anyways, that car makes me appreciate the creature comforts that my BASE GT has to offer!!!!!

Thats another thing...clutches for these newer cars are priiiiceeeey BUT they have unbelievable holding power without the heavy pedal feel.  I NEED that in the 66.  If I had gone with a 250 inline I could have run a fox size flywheel, centerforce dual friction (one of my favorite clutches) or similar and a cable to make everything wonderful.  Nope...now I need to find someone who can put something together that I can use OR take the risk of trying out the Fairmont pressure plate and seeing if itll hold with my custom dual friction disc.

Fun night at the Hill but the air and track conditions presented some odd results.  Every single pass I would hook really well on the launch while slipping the clutch but the second the clutch was released fully it would spin hard and throw off my 1-2 shift which would then spin hard.  No wheel hop this go around, just spinning to the point where I had to pedal both at the top of 1st and into 2nd which Ive never done before.  Despite that, it would back half the track like a freight train and I would pull off decent times.  My first and worst pass I went WAY too soft on the launch trying to see how the track was and actually bogged it hooked so hard resulting in a 2.2 60ft and then I shifted the 1-2 way too high and spun my butt off and still ran an 8.3 @ 91.  Next three runs were 8.11, 8.08 and 8.03 all with better and better 60's but still spinning the top of first and the 1-2 shift.  Im pretty sure between the 60ft and 330 ft is where Im losing all my time spinning or hopping.  Either way I still had fun.

I figured last night was going to be a HOT one and that no records were going to be broken so to spice things up I decided to give the Nitto NT555R's one more shot just for kicks.  Figured if nothing else I would try to get some decent 60's and see where it leads.

IMG_20170613_194109613_zpsythmzvmk.jpg

Hot doesnt even describe it.  I was melting out there BUT the track was hooking like crazy and I was able to click off a couple high 1.8 60s on very very easy launches.  I tried to get a little more aggressive and would bog like a mofo both resulting in mid 1.9 60s.  Even the 1-2 shift would hook without even a chirp except on one pass which was actually my best 60 of the night but ended up being a bust cause I missed 3rd and just finished the run in 4th instead.  I got 5 runs in less than 20 minutes too because NOONE was going back to the lanes.  Only downside was the shorter tires forced me to take the extra 3-4 shift at the end as I would bounce off the limiter in 3rd WEEELLLL before the finish.  Here are some of my times:

1) 7.96 at 89 with a 1.93 60.  Straight off the road, 22psi cold in the tires, lazy launch to get a feel for it, bouncing off the limiter in 3rd quite a ways before the traps :lol: 

2) 8.33 at 83.05 with a 1.86 60.  Slightly more aggressive launch, missed 3rd finished in 4th gear.

3) 8.18 at 90.17 with a 1.98 60.  Tried to let the clutch out quicker and bogged big time.  Shifted to 4th at end of track from here on.

4) 8.36 at 86.68 with a 1.95 60.  Bogged again, missed 3rd again.

5) 7.96 at 90.49 with a 1.89 60.  Eased up on the launch, shifted every gear around 7200 rpm.

Like I said above, I was hot lapping like crazy and with the temps being 90* and the DA around 3200 Im happy as can be with those times.  Apparently when the car grips it doesnt like to shift 2-3 sometimes, Ill look into it.  If I would have stayed longer I would have liked to mess with the launch a bit more as well as my shift points.  With full grip all the way down the track Ide like to make a couple passes shifting at 7200 like I was and then compare to a couple passes shifting around 6800 or so.  With having to shift to 4th and it being so damned hot, I was happy to take my slips and head home PLUS someone oiled down the track so I bolted.  Gonna pull these tires off the wheels and look for something taller, either a set of Mickey Thompson R's or maybe even look at some M&Hs but I was surprised at how well these things hooked up.  Oh...and apparently I have to find a helmet before I go back.  The guy handing out the slips and the guy directing the lanes were both radioed and told to tell me for some reason.

Fun for sure!  Working on my driving and working around the track and weather conditions has been great fun.  Glad to have a car thats relatively quick, reliable and that I can work on my driving in and see tangible results.  The SVO back in the day would run like a raped ape up the twisty backroads to the track but once up there it was a turd and often wouldnt even run well enough to get around the pits cleanly much less down the track.  The ST being FailWD was a pain in the ass no matter what I did at the track and the 66 was/is cursed.  Runs good on the streets, put it between two concrete walls with timing equipment and it shuts down and fails you.  The BlueCoupe and now the GT both loved every minute of it.  The trip to the track and back were fun and reliable and it would get down the track and be fun to drive no matter what conditions.

No, with a clutch and 2.41 gears it ran a 8.004.   Clutch dump at 5500, SPIN HARD for a couple tire revs, then bog hard.  Cleaned ALL the rubber from the left starting line in two spots about 2 feet long.  lol

It wasn't as fun as Matt's Mustang because I didn't trust my driveshaft or rear axle enough to drive it to the track.

Awesome! :up:

I hope to catch up to you soon. Dang parts are coming in slow and the weather is starting to get miserable, so I'm going to have a hard time getting motivated to get out in the heat in the gravel to work on this thing. I need a garage with AC! :yes:

Disney has one!  You can use my driveway too anytime, its a small step up from gravel thats for sure!!!  You need to get yours going or else Ill be happy with where the GT sits for longer than I should and not want to waste money making it faster which would be WAY too responsible of me and we cant have that nonsense!!!!!!!!!  Altho in all reality...not much more I can do for cheap and cheaps all I got!

Not much to report and I didnt take any pics :shiftyeyes: but I crawled under the GT last night and installed the shifter bracket I got from Full Tilt Boogie and went ahead and changed the trans fluid to BG Syncro shift II.  The bracket eliminates the body mount on the rear of the shifter and essentially directly mounts it to the transmission which helps eliminate shift issues (especially 2-3) when the motor is twisted at full throttle.  I actually quite like the new shifter Ford put together for the MT82 in 2015+ and that was pretty much my only gripe so rather than spend $500-600 on a shifter :???: I spent $70 and an hour under the car.  Feels muuuuuuuuuuch better and I can say that the hype of the Syncro Shift II is pretty spot on as well.  Trans shifts smoother, less gritty/chippy between gears and the shifts feel more confident with the bracket.  I pounded on it last night trying to see if I could replicate the instances where I either got locked out of 3rd, went from 2nd to 5th or just plain missed 3rd in general and couldnt make it happen.  Only time at the track will tell tho but hopefully this $70 part will save me from myself and from having to put down the cash for an aftermarket direct mount shifter.  Now to pick up a cheap helmet and scratch together the funds for some sticky mickeys and Ill be back out.
