I have my doubts about going to the track tomorrow. 30% chance of thunderstorms. That's not the big issue. The issue is the temperature. It's supposed to be about 90* with 75% humidity at 4pm when the track opens. If it's that hot out going would be a waste of time. That's around a 3000ft DA. Blah.

The longest winter followed by the weirdest summer that at least by me, had no long heat waves like years past.... I love the heat too.

STILL haven't touched the car to change over. It's been in the 50's here at night now. PERFECT running weather. Cougar's been running like an animal. Atco's been doing night rentals...... I should set one up.....

Why do you have the cool weather now and it's now hot here? Before I did the swap it was nice and cool here. Now that I got the new filter and airbox it gets warm. Too warm to go to the track and get a good run. Stupid weather. I'm still holding out hope that next Friday (September 5th) is nice. If not I'll have to go to the far track in October (that one is an hour and a half away).

Far? Hell an hour and a half is the closest track in perfect zero traffic conditions (which NEVER happens).

I've got one track that is 45 minutes south of me and the other is a hour and a half drive north of me. Obviously I have a near and far track. I would rather go to the close track as, well, it's closer and newer (hence nicer).

I was able to run at the track last Friday. Here's the results:

This year(K&N conical filter in March Ram Air Box)

Temp: 76*
Pressure: 30.20
Humidity:43%
60': 2.25
E.T.: 14.442
MPH: 96.02
Corrected for DA: 14.153 @ 98.022

Best run last year(K&N panel filter in stock air box):

Temp: 65*
Pressure: 29.84
Humidity: 60%
60': 2.108
E.T.: 14.129
MPH 98.01
Corrected for DA: 13.96 @ 99.4

I forgot the stock air box and sample tube to make back to back runs to correct for weather conditions. Duh:hick:. DA calculator is the best I could do. Some notes on the results though:

Last year's best run was made with 18* initial timing. This years was made with 16*. I usually run 18* at the track (usually worth 1-2mph on my setup) and 16* on the street to reduce the chance of detonation on a hot day with the A/C on. In addition to forgetting the stock air box and sample tube I also forgot my timing light. Great day on my part :hick:.

The track was slick as heck this year. 2.25 was the best 60' I could cut that night. I can usually cut a 2.1 spinning of the line. Last week the car was not only spinning off the line but also barking the 1-2 upshift. The .15 increase in 60' probably accounts for ~.2-.3 in the quarter and 1-2mph or so.

So realistically the two setups are about even. If I get the chance over the next couple of weeks I'm going to try driving to a different track (in better weather conditions) with all the stuff needed to make back to back runs. Considering that the conical filter setup was running pretty much the same as the stock air box with less timing there might be a slight advantage to the conical setup. Realistically though I need drag radials. With a decent 60' (1.8-1.9) I've got a mid to high 13 second car. Not bad for 3700lbs and 306ci

You've got too many variables with a lot of time in between to compare accurately. How are you launching? My car prefers the converter loaded up as opposed to a quick flash. The Mustang is the exact opposite.

Are we seriously still debating air boxes after 3 pages...? :hick:

I should read through it all to make sure I see all of the data....but a friend of mine was a real dope not long ago and pissed me off. He has a 2V new edge Mustang with a Vortech V-1. His cone filter is at the BOTTOM corner inside the bumper. What did the jackass do? Drove in the rain, huge-ass puddle, stall. FLOORED THE PEDAL and tried to crank it. Now he has to rip everything down. Broke something...guessing a rod.

Now....*IF* you race professionally or are super-detail oriented about your time and every tenth or hundredth counts, okay, attack every last detail. But it seems so many people miss the economics of it, and fuss over something like this (my friend's not alone...all of the Honda people put their turbos IN the face of the bumper, no filter, nothing!!!) and forget that they're driving through the asphalt jungle, replete with dead animals, potential water, leaves...debris of all kinds.

You won't feel it in the butt dyno....

My interest was twofold.
1. Actually having enough airflow for my combo.
2. Getting/keeping intake temps down.

If you read through, you'll see that a stock air filter aint gonna cut it for me flow wise....

No kidding. Well...I mean well over 1HP / CI is significant power density...and there's certainly plenty of airflow to make that happen, with your custom cam (as has surely already been addressed), the revs may get high enough to need less restriction.
Bottlenecks here, bottlenecks there...they all rear their head at some point.

Launching from idle I get wheel spin. Launching off the converter I get hellacious wheel spin. For example back to back runs from last year:

First run leaving from idle:
60': 2.17
E.T. 14.33
MPH: 97.03

Second run leaving just below stall speed(2800rpm stall):
60': 2.67
E.T. 15.74
MPH: 95.52

I my car's case traction has a lot to do with mph. The better 60' the car cuts not only the better the E.T. but the mph goes up as well. The car is in bad need of drag radials. I want to swap intakes (right now the GT40 lower is stock so at 205cfm of flow it's flowing 40cfm less than the heads) but I need to get the 8.8 in the garage built first. This way I can run drag radials and at least get consistent 60' times.

Plus some of us are never satisfied and just want to hot rod for the hell of it

I knew several people that spent money on car audio in or shortly after high school. Especially subwoofers, of course. I never had this and sort of always wanted it.
The black cat came with a somewhat built-up audio system. The P.O. wanted to keep the bass tube in the trunk. So eventually I found some deals and now have thumping bass when I need it, and powerful mid- and high-range from the component speakers. Half the time I drive the cougar JUST for the stereo system

How fickle of a person I am.......the speed itch will return, eventually it will feel slow I'm sure!

Get in something that's relatively slower for a while and drive it on the regular. Taking the toy out after that will give you an appreciation for it and the want for even more.

FWIW -- I've found a Mustang set up almost identical to mine save for an aftermarket converter. Same trap speeds and MUCH better 60 foots on what should be less aggressive rubber for the track. He had a LOW 1.6 60 ( I'm in the high 1.7's) and 11.7's all day long. I'm ordering my converter this week. 4000 RPM stall here I come.

Driving my red car with a 3000 rpm stall, I *am* curious as to what this thing would do with a good auto setup. Would surely be a blast.
My daily is an '87 Grand Marquis and has been since Nov '13. So no worries, there's a stark difference. Especially after all winter long of 150 horsepower :hick: BUT IT'S GOT 3.27s!!!! YEAH BOI! Really though, was sooooo stoked to find out it didn't have 2.73s like my Vic did....

OH AND BTW!!!! Took the Carquest paper filter out of the black car and drove it a mile or two last night. Didn't notice an appreciable difference in acceleration. And it definitely just...stops at 5500. Hesitates and then kiiiiinda wants to keep accelerating just a little but it's over. So yah...I guess I'm alright. I might think of getting a different cam at some point, have another 700 rpm until the limiter...
