    Default Cobra's Back in Action! New Personal Best ET & MPH! UPDATE 10/21/14

    Hey guys and gals, it's been awhile since I've been to the track. As some of you may know, last summer was the summer of hell for me in terms of what was going on with my Cobra. It began on Memorial Day when I came out of the gas station to see that someone had backed into my door, creating a dent the size of a soccer ball - while it was still parked at the pump! After almost three weeks in the body shop, I got it back and decided to buy a 347 stroker motor that my brother had built for a friend of ours. I pulled the old 306 dual quad motor out, installed the new 347, and then drove it for three weeks without any issues before taking it to the track. While at the track, the crank decided to eat the thrust bearing, trashing the rotating assembly. For the rest of the summer, there were no Yellow '79 Cobra sightings anywhere in New England.

    Depressed and bummed out, I had two options from which to choose. Option number one was to reinstall my 306 dual quad motor and sell off the parts of the 347 to recover my money that I had paid for it. Option number two was to work a ton of side jobs to create the money that I would need to fix the 347. I chose the latter and I'm glad I did. Somewhere in mid January I had finally acquired the funds that I needed to rebuild the 347 so I pulled the motor and I gave it back to my brother. A brand new Eagle crank was ordered, along with new bearings, gaskets, and piston rings. From there he went to work and fixed it up. In mid-February I was able to reinstall it back into the Cobra and it's heart was beating once again. I drove it as much as possible to work the kinks out and sometime in March we took it to Mike Dez racing in Seekonk, Mass to be tuned. With my brother and I making the necessary jet changes, and Mike working the dyno, we were able to put down 420 rwhp/380 rwt and the air/fuel graph was just about perfect. Since then I've been driving the wheels off of it with no trouble at all. In fact, I've put 2,400 miles on it since February!

    Fast forward to this past weekend and my brother and I, along with three of our friends, made the 3 hour trek to Lebanon Valley Dragway in New York to see what it would do at the track. I was confident that it would make the drive there but was paranoid that it was going to break. In fact, after I installed my ET Streets and lowered the pressure down to 12 psi in each tire, I began to get butterflies in my stomach because I didn't want to break it! I also didn't want anyone in our group of friend's to break any of their Mustangs either. As much as I tried to deflect the nervousness, I simply could not get past it. To complicate things, it's been two years since I've had any type of regular seat time at the drag strip so that was weighing on my mind as well.

    That all ended when they called my class to the staging lanes for our first time trial. As I moved down the staging lanes, I buckled my seat belt, put on my helmet, and waited for my turn in the burnout box. Once in, I spun the tires to get them wet, moved forward three or four feet, and fumbled my way around for the line loc button. Once found, I did my burnout and moved to the line. Before I knew it, the lights were coming down and I had no idea where my rpms were. I was hoping they'd be somewhere around 5,000 rpms but I wasn't sure (I don't have a two step). I dropped the clutch and I spun the wheels hard on the launch. I went through the first two gears, banged off third, and that's when I could tell I was flying. I ripped off 4th gear and headed for the finish line. On the return road I picked up my time slip to find that I ran a 12.0 @ 117 - up from my old 306 best of 12.3 @ 111! With that MPH of 117, I knew I had some 11 second time slips in my future.

    I ran the car three more times (missing gears, sleeping on the line, etc... - talk about being rusty!) before I got that coveted 11 second timeslip and when I did, I went 11.98 @ 116. I followed that up with a hot lap run where I went 11.99 @ 116. I was now ready for my brother. I chose the left lane and he chose the right. We both did our burnouts and moved to the line. I pre-staged/staged first because I wanted to bring my rpms up to 4,500 and hold them there while I concentrated on the lights. Down they came and off we went. I banged off 2nd at the same time as him and looked over to see him looking at me. We both banged off 3rd at the same time and looked at each other again. Down the track we went side by side until it was time for 4th gear. We both ripped them off at the same time and looked at each other again. The finish line in sight, we were side by side and neither one of knew who had won as we crossed the stripe. I knew right away that it was the best run that I'd ever had in my life.

    On the return road, I stopped to get my time slip. The young kid at the booth said, "Wow! That was a close one!" I replied, "Yeah, I don't even know who won!" He then looked at the number on my side window, looked at the time slip, and said, "It wasn't you." DOH! I was crushed! After looking at the time slip, my best ever time of 11.86 @ 117 wasn't enough to beat my brother's 11.91 @ 117. His reaction time was a little bit better than mine and that's how he won the race.

    All in all, I had a great weekend as I drove three hours out there to race, made 13 passes between the two days, recorded my best ever pass at 11.85 @ 116 (on Sunday, the next day), and then drove the three hours home - all without breaking. I can't wait to do it all again!

    Glad to hear you are driving and having fun. Its too hot in the summer down here in FL for me to roll around in a black car. Have not driven my car in months. Waiting for fall. There are too many summer tourists clogging the roads and there are no close 1/4 mile tracks either. Track time may need to wait a few years until I retire and move back north.

    Nice to see you get back out. It is surely exciting to cross off one of those milestones and be able to say you have an 11 second car.

    Once you get some seat time back in it and dial it in, the potential is there to need a roll bar

    Oh, thats neat, pipped by the bro at the reation time.

    I just love it.

    From the details you have, you have to have about 530 flywheel hp to make 419 rwhp. So once you get things ironed out, you gonna need a birdcage.

    Based on 11.91 sec 1/4 mile and 117 mph top speed from http://www.wallaceracing.com/hpcalculatorquarter.php

    Your HP computed from your vehicle ET is 315.88 rear wheel HP and 350.97 flywheel HP. (They use a nominal approx 10% flywheel to rear wheel hp loss, which is only realistic for a transbraked auto or some kind of Lenco or whatever)
    Your HP computed from your vehicle MPH is 346.30 rear wheel HP and 384.78 flywheel HP

    The manual and bigger differental power loss with the rolling resistance of the those fat feet is about 28%, so you need 443 hp minimum get the 117 mph you have run.

    What a lovely car,m and such a standout engine.

    Thanks guys! It surely was a lot of fun and I can't wait until next year. My only complaint is that it is so far to go to the track and I had to burn about $150.00 worth of gas to get there, race, and get home. If I add in the $35.00 per day to race, the hotel, and the food, it prevents me from going every weekend. If I had a track within 20 minutes from home, I'd be there every Friday night!

    So good to hear those problems are behind you. I know your car isn't some stripped down race car so your times are very impressive. Not many cars look as good as yours and can still run those times.

    Your complaint is the same as mine. I have a 200 mile round trip to race and feel I'd go more often if there was a track a lot closer. Back in the '70's we had a track 5 miles from where I live. Wish it was still there!

    I know that nervous feeling the first time back at the track after losing an engine there. Funny how you completely forget it once you roll into the beams.

    What are your 1/8 mile numbers? At least then I have something to compare to.

    I'll try to get some video's. My friend Will took a few on his smart phone and I watched them but that was on a small screen. I have no idea how they'll look on a computer screen. I'll see if he can e-mail them to me. If they look decent on the bigger screen, I'll post them up. As for my 1/8th mile times, they looked like the two posted below, which were my best runs.

    1.641 - 60'
    4.935 - 330'
    7.636 - 660'
    92.04 - MPH
    9.943 - 1,000'
    11.86 - 1,320'
    117.78 - MPH

    1.61 - 60'
    4.92 - 330'
    7.61 - 660'
    92.26 - MPH
    9.92 - 1,000'
    11.85 - 1,320'
    116.88 - MPH

    I did have some lower 60' times and my best was a 1.61. I also had an 11.85 run but the MPH was lower at 116.88. Also, this track is 850 ft. above sea level and the D.A. was horrible. I'm confident that if I race it at New England Dragway (which is only 90 feet above sea level), I'll be able to knock two tenths and gain 2 mph. Plus, more seat time will help as well.

    Thanks for the replies guys! I've uploaded a video that was taken from a camera phone so the quality is not the greatest. This particular video is not the race I described in my first post. On this run, my brother got me out of the hole with a .084 reaction time vs. my horrible .213 reaction time. That was the difference that gave him the win, even though my 11.85 @ 116.88 was both lower on the ET and faster on the MPH. He ran an 11.96 @ 116.04.

    My best the night I hurt my torque boxes was a 7.59 at 94.74 mph. Track closed and have not been back to a track since. That was four years ago. Since then I have the battle boxes, new camshaft and a tubular k-member.

    Since all of our numbers are so similar I bet we are at the airflow limits of the AFR 185 cyl heads.

    You're probably right on the AFR limits. I'd like to go up to New England Dragway in New Hampshire sometime early next month to see if my numbers will be lower up there (90 ft. above sea level vs. 850 ft. above). My brother's car usually runs 94+ in the 1/8th at NED but he was running what I was running at LVD (92). His quarter mile times are regularly 11.6's @ 118 but his best ever is a 11.440 @ 120.

    That's great Pete. Good to hear it's back in action and reliable. Not to mention running neck and neck with Paul's car. That's awesome.

    I've always admired your Cobra and am glad to see it's back in action. I was there Sunday at Lebanon Valley with the Futura and didn't get to see you race because I was so busy talking with people who couldn't believe a Futura Cobra.

    You mentioned needing a drag strip closer to home. What are they doing with the runway at the old South Weymouth Naval Air Station?

    Thanks guys. Rock, I didn't even know you were at Musclepalooza because I didn't get a chance to get over to the show car area until after I was all done racing. I saw a picture of your car in the background the following day on one of those online picture services that LVD uses, and thought to myself, "Damn, Rock was there?" I did get over to take pictures of the show cars but it was while they were giving out the awards and a lot of the cars were either leaving or had already left. I apologize that I didn't get to see you. As for the South Weymouth Naval Station, I believe that some of that land has been converted to Condo use but there's still a lot of it available (at least there was the last time someone spoke to me about it). I also heard that there was an auto cross track on that site but I don't know how true it is. I'd love to see them build a dragstrip on Cape Cod, right on Otis Air Force Base. That would be awesome. Unfortunately, the beaurocratic red tape would never allow for that.

    Awesome times dude.. It looks like you were flat shifting. Also what was your rpm when crossing the traps in the 1/4?There maybe some et left in your gearing..

    Brian, that's funny. LOL! It'll be worth it in the end though.

    As for my shifting, I do use the clutch and don't power shift. Because I drive it on the street 99% of the time, I'd like to keep it in working condition without grinding. LOL! As for my RPM while going through the traps, I never looked at the tach so I can't tell. I know that when I launch, I'd love to be able to leave the line at 6,500 rpms. However, anything over 4,500 rpms and the tires will spin - even with 12 psi in them. I'm sure my street suspension isn't helping in that area!

    Here's a picture of my brother's '85 GT pulling a wheelie. He's done this enough times that I'm envious because mine won't do it - even though my '60 foot times are either the same as his or a tad bit quicker! Even when he had his old 306 dual quad motor in it, he could still pull the wheels. Impressive for a street car! Oh, and he pulled them up on one our runs too!

    Do you have a link to those pictures? I went to the LVD website and found pictures taken on Sunday, including one of your car staging up to the lights. No picture of mine. Maybe I didn't wait long enough to download.

    A dragstrip at Otis would be great. Since Otis is technically an Air National Guard facility, I don't know whether it's State or Federal property. I used to know the Civil Engineer squadron commander at Otis nearly 20 years ago - I was Civil Engineer squadron commander at Westover at the time - and I'm sure he has long since retired. The current Adjutant General in Massachusetts is an Air Guard two-star named Scott Rice. While I don't know him, one of his sisters was a high school classmate of mine. I had a crush on her back then. She was, as still is, a doll.

    Rock, I don't have a link and I cannot remember where I saw it. However, in the picture, Doug Moglin's car aero fox was featured and I saw yours next to it. Maybe it wasn't on one of those picture sites? Maybe it was on facebook? I can't remember now!
