Didnt answer your second question Doug, there was a cross wind not much maybe 10 miles and hour. Not all three days but i think on Saturday it was.

Nice Chilly thanks for the pic.

I love that Mustang.  The lime gold is gorgeous.  And a great engine combination, too.

Ok Found it!
(For the exhaust open vs closed comparison)
Can you add:
What cam?
Which headers? (1-3/4 or 2-1/8 race supercomps)
Compression?

Also, when you ran the open header setup, were you carrying the exhaust system weight too? Probably 40 lb lighter without it at least.
Looks like at least 0.2 sec and 2+ mph gain running 'open"

cam 280-288  lift 621-624 250/254 @50  lobe 112
hooker super comp 1 3/4
I wasnt carrying the exhaust on my 11.07 pass.
compression 10.75.

Just a heads up Werby Im gonna have a new set up this year.
Maybe not much,,Different cam alittle head work probably enough to get me into the 10s.
I mean I only need .07 Im sure Im gonna get that. May have gotten it with alittle cooler weather.

Thanks LOL I forgot I'd started Gonkulating this about a year ago in this thread! Cant find it all tho so not sure what I guessed at.

Gonkulator says the MR intake is adding about 23 Torq & 30 HP vs the LR intake.
About .15 ET and 2 MPH better than the LR.
That's if weather, driving, track & tune are all the same.
Gotta be knocking on the door of the 10s already.

What about more converter? Torq peak is 4000-4200 in the Gonkulator so near 4000 stall might be ideal, especially if you add more cam.
Then again, not as streetable.
Admirable goal to have a street car in the 10s just by ditching the exhaust!

[Stangman]

Like I said I’m at 11.07 with the exhaust off. So I just need a smidge. I know I can get into the 10s with a little cooler air and a smidge more tuning but I’m already in the works with a new cam and bigger valve in the cylinder head ( intake). Other than that maybe some port matching no porting.

You gonna get that 10 sec pass this fall?
‘Round here the tracks close end of this month.

So I just got back from the Reunion and as usual we had a great time. So I got my motor in the car and took it for a ride only a week ago so it was the mad rush to get it together. I don’t know how but we made it. So anyway around town all seemed pretty good but at the track the car was a dog off the line. My 60 ft times are usually in th 1.53 to 1.55 with the previous motor and except for one 1.52 on Thursday I wasn’t getting anything better than a 1.57 and most were higher especially Saturday they were all 1.59. I wasn’t going to change a lot of things at the track so we just tried to be as consistent as possible with what we had. Now my best time previously was a 11.07 at 121.87 if I remember correctly I could go back and check but I’m not. My first pass was a 10.97 at 122.45 so I was happy to be in the 10s but I was really hoping for more. Fiddling with foot brake rpms I did run a 10.93 which is my best time but that was with a 1.57 60 ft time. I will be making some of my own adjustments on the carbs before the next time out  to get those 60 foot times in the low 50s to high 40s I hope. I made like 11 runs and they were all between 10.93 and 11.03. So in eliminations I made it to the third round but I was helping someone with there car and didn’t here them call hot Fe and when I realized that there wasn’t a lot of cars near me I asked my daughter if they called hot Fe and I jumped in my car drove up to the staging lanes and there was one car left in the lanes and he had the bye. I drove right past him and the guy I raced was just starting his burnout so I rushed up there and did my burnout and  I had my dial in at 11.01 cause as the day went on my car was slowing up so anyway I redlighted and normally you can see that but I didn’t and I ran it out and ran a 10.95 anyway so the moral of the story is pay attention . Anyway got to meet a few more guys up there and had my daughter and Harry helping me in the pits. It was good to see Steve and Ed again. I haven’t made a pass in 2 years so being that the car wasn’t up to snuff and me being rusty the weekend was a success and nothing broke. Well my temperature gauge broke on the second to last run. So I would like to get out one more time but I’m not gonna go if I can’t play around with the carbs.

Well all right! I’m sorry I did not get to connect with you and congrats on the improvements. Nice to be in the 10s and very consistent.  It must have been a thrash after just getting engine back. ( For me it seems like it’s always a thrash for one reason or another, lol).

[Stangman]

Were you there 6667 I got to see a bunch of guys  that I talk to on the forum.

[cjshaker]

A real 10 second street FE. That is really quite an accomplishment, Joe. And on your first run! The weather looked decent, but I didn't notice humidity or altitude (I do know that humidity at night was high). I'm sure you'll squeeze out a bit more as you tinker with it. No issues with the engine has to feel good. Nice job!

[Stangman]

Thanks Doug we missed ya maybe next year. The car is very sluggish off the line, I’m gonna play around with the carbs but I’m happy I didn’t break anything. I think after I get to were I want to be I’m hoping for another couple of tenths which isn’t as fast as I thought it would be but I’m reluctant on getting a bigger converter. I don’t see why I can’t get it to run in the 10.70 range with the proper carb tuning to get the 60 foot times were there supposed to be.
