Well the weather was perfect,but the traction,at least for street radials was not. The best of three runs was a 14.11 at 99.7 MPH. I tried
coming off between 1500-2200 RPM and slipping the clutch a bit. The car would light'em up in first,get sideways into second and break them loose into third. The first and best runs were running thru the traps in 3rd gear at 5800 RPM.The last run came at night,had the best 60 ft.,at 2.032,vs.2.23 and 2.165,but I decided to short shift into 4th at 4500 rpm,to try to get a good run in 4th before the finish. However that slowed me to a 14.20 at 96.5 MPH. That last run may have been the magic 13! You just have to luck out on the best launch and best shift point into 4th maybe.The second run was a back to back run,and the car was at it's warmest point,and I thought I heard some detonation in third gear. I was running on Ammaco 87. Didn't notice it on the last and cooler air run. I just got my latest issue of MotorTrend in the mail today. They road tested a Bullitt and got a 14.07 at 97.9. Just like the 5 speed 5.0 Mustangs of old,the key is traction,traction!!!!!

Thanks for the update. Did you let air out of the rear tires? I think 25 psi would help.
Also did you go around the water and just do a quick burn out to clean off the tires?

 

[Mus408]

Ray,I had the rear tires anywhere from 30 to 27 PSI,during various runs. I had the fronts pumped up to 43 PSI. The track workers made sure the water was spread ALL ACROSS the lane,with no way to get around! Had to drive thru the wet,and spin'em up to dry them off. The car just loves to break'm loose. I am sure a 13 is in there,just need the track,or a street slick! But I am happy,it is more of a road machine than a drag car.

Your Right the BULLITT loves to brake the tires loose!

hmmm. sounds like Houston Raceway Park is a little better prepped.

They leave a "hole" of dry pavement for the street tire cars to manuever around. I found 25psi to work best for me with a launch of 2600. Feather the clutch and then hammer it. I can plant the 1-2 and 2-3 shifts out there with a nice chirp.

My best 60ft is 2.015, although my best pass came on a 2.167. Go figure??

13's sound very close for you!!

I may put on the Drag Radials,from my 85 LX and try again this morning. They are about 1.5 inch taller and about 9 inch tread with. The extra height should let me leave at 3500 and give me a bit more MPH in 3rd gear thru the traps! Hope the axles and clutch can take it. This will be a one run deal! I'm lookin' for that 13.6 JB!

Good Luck!!

 

[JB VOBRA]

Mus, good luck! That taller tire should effectively change your gearing ratio from the 245/45 17" tire. And the traction should improve greatly, especially since it sounds like your track is an ice skating ring.

I wouldn't sweat the stock parts; my blown cobra made several 1.7 60ft launches on the stock axle with no problems. I say "Go For it!!" It's those chevy rear-ends that are like glass.

I'm sorry to read about your F250 mirror problem!! Did you make it to the track today?

 

[Mus408]

Update....I tried fitting one of my 15 inch Torq-Thrust wheels,off of the 85,onto the Bullitt,but the inside of the wheel hit the brake caliper. A .300 inch thick spacer would help clear it,but that didn't leave much axle stud thread length. Well it was an idea!
