Went to Martin last night!
1st of all, a big THANKS to falconcritter for letting me borrow his 250 2V intake until Mikes 4 Bbl intakes come out!!
Drag200stang came all the way across the state of Michigan to watch! Had a lot of fun talking to him and talking and talking....
He helped a bunch! Thanks!!!
Also met a couple (forgot thier user name?) That check in on the forum, but are on turboford. He has a turbo 4 cylinder Mustang and she has a turbo 4 cylinder Pinto. Nice talking to them too!!
1st pass right off the trailer was a 16.31 @ 83.97 didnt get on it very hard being it was the 1st pass and I wanted to warm it up a bit.
heres all the times,
60' 2.29 1/8 mile 10.01 @ 70.40 1/4 mile 15.67 @ 85.71
60' 2.23 1/8 mile 9.91 @ 70.78 1/4 mile 15.54 @ 86.20
60' 2.26 1/8 mile 9.89 @ 70.98 1/4 mile 15.51 @ 86.22
60' 2.22 1/8 mile 9.91 @ 70.09 1/4 mile 15.57 @ 85.89
I was shifting around 6000-6200 rpms but it didnt feel quite right at the upper rpm ranges
Next thing I did was pull the airfilter top and filter off the car because my K&N filter had not came in yet and we cobbled up the filter base with some tie straps so it wouldnt fly off!
60' 2.40 1/8 mile 9.92 @ 72.71 1/4 mile 15.38 @ 89.10
Much better now!
Pulled the plugs and they were white. I used to run #67 jets in my log head and it had a huge lean bog after I installed the aluminum head so I switched to #69 jets and that improved it on the street. Also had a blown power valve so installed a new #5 valve.
Pulled the bowl and swapped to #72 jets and made some more passes!
60' 2.22 1/8 mile 9.78 @ 71.88 1/4 mile 15.33 @ 87.43
60' 2.26 1/8 mile 9.83 @ 72.10 1/4 mile 15.32 @ 88.77
Now earlier I had to lower my air pressure in my rear tires to 26 lbs becuase I 'm starting to get a lot of wheel spin. I need to get some sticky rear tires!
60' 2.34 1/8 mile 9.85 @ 72.37 1/4 mile 15.31 @ 89.13
60' 2.22 1/8 mile 9.79 @ 72.16 1/4 mile 15.28 @ 88.94
My best last pass at almost 11:00 that night when the temp mid 50's was,
60' 2.53 1/8 mile 10.11 @ 71.98 1/4 mile 15.6 @ 88.60
Note the 60' time and 1/8 mile time then the 1/4 mile trap speed. Almost the same mph as my fastest pass but a lot slower 60 ft time and 1/8 mile time.
I basically drove it off the line and stood on it about 10 feet out. If I had better tires so it would hook up I am confident that the last pass woulda been in the 15 flat to 15.1 range!
This is the exact same setup as my log head except there is no cold air setup on the aluminum head. All I did was play with the jets...I never moved the timing at all or did anything else to the car.
I weighed it and with me in it it weighs 2748 lbs.
I'm confident with some sticky rear tires and a bit more tuning it will run a 14.96-14.99 @ 91
So the moral of the story is,
Modified log head Best ET 16.11 @ 83.65 mph 2.34 60'
Classic Inlines aluminum head 60' 2.22 1/8 mile 9.79 @ 72.16 1/4 mile 15.28 @ 88.94
I ran the numbers through an online hp calculator and heres what I got,
Your 66 mustang weighs about 2748 pounds and can complete a 1/4 mile in about 15.2 seconds. That means that you've got about 154.66 HP at the wheels, and about 201.06 HP at the flywheel.
I think this will make Mike extremely happy!
