Dang I totally forgot about that car show. Course going to the drag strip was my car outing for the weekend, maybe for the month. Gas is like 3.31/gallon. Crazy!!

3.31? come on, that is below national average. It's 3.81 for 87 octane where I live. I just had to pay 4.01 a gallon for 91 to put in my ranchero.

Just paid 3.49 for 87 at costco here. 91 is 3.7 something. Then you get bent over for Diesel at 4.33 Fuggers.

at least his 60 ft time was lower than the cost of gas

post up that slip lets see it

amazingly enough i'm pretty sure the big body 71-73 cars are still lighter than the fox body cars, believe it or not but i'm not sure what a BB vert weighs compared to a fox hatch though, might be right around the same.

Mustang Red book: 71-73 with the 351----3560 lbs (doesn't list the convertable, that'll add another couple hundred pounds) 79-93 listed as 3075 with the V8. jikelly's out weighs a Fox body by about 700 lbs.

That's what you get for living in states that frown on drilling for oil & gas. :rlaugh:

Down here in south Louisiana cheapest gas is 3.35 /gal for 87 octane. (and that's too high for me, but apparently it's not high enough, you still see em lined up at the pump and driving 90 mph on the interstate in their SUV's)

As if that actually makes a difference. They pulled the stuff out of the ground right around where we lived in Midland TX and our prices were still 10 to 20 cents higher a gallon than places 100 from us in all directions.

Anyway, I was dumb and forgot to post my slip for y'all. I'll get it up tonight. My old car weighs a lot. I figure she's around 3500lb.

Vinyl66 · Apr 22, 2008

If your track has a scale it would be nice to know the actual weight of your car. I'll bet it is over 3500. Those big converts are pretty darn heavy.

Even if race weight is in the upper 3000's, 248rwhp should be enough to get you in the mid 14's.

Use this calc for 1/4 mile calculations knowing rwhp and weight.

i'm betting that weight for the fox bodies is listed for the base 4 banger cars. i know the v8 GT's weigh a lot more than that, closer to 3800 when it's all said and done, i believe. they are actually pretty portly cars and the sn-95 weighs even more than that.

CornerCarvin67 · Apr 22, 2008

If you're really curious... maybe I can run my Fox over the scale here after work.

I'm curious myself...

Vinyl66 · Apr 22, 2008

My old '89 Mustang Convert weighed 3330 lbs. with aluminum wheels and a 4 pt roll bar. It had AC,PS, and electric everything. Most stock LX's are around 3200 lbs. It's not too difficult to get them into the 3000 lb range.

bnickel · Apr 22, 2008

ok, well i guess i've been misinformed all this time, apologies guys.

cornercarvin67, i'm still curious though so if you want to run it over the scales i'd be more than happy to concede once and for all

D.Hearne · Apr 22, 2008

The Red Book listed the 4 banger cars as 2875 (140 cid motor = 4 cylinders, right?)

i was getting my info from somewhere else and from more than one source i was getting the same weight info, incorrect as it was.

Hack · Apr 23, 2008

My '83 T tops GT was listed at 3400, but I never weighed it. That's probably one of the heavier Foxes available...

Alright I finally am getting my time slip data up for your expert analysis. I entered the data in Excel and figured the seconds between the various distances I had times for. I was doing that in an effort to figure out my acceleration between points, but my excel formula is crude and I came up with a little crud I think. Any idea how to figure acceleration?

you just need some time behind the wheel and work on your 60ft. get them under 2.0 and you'll be sitting comfortably in the mid 14's.

Vinyl66 · Apr 24, 2008

Your 60 footers are really bad. Get them down to 2.2 (still bad) and you will be in the 14's easily.

bnickel · Apr 24, 2008

yeah 60 ft are horrible and it looks like you might be losing a little on the top end....what gear were you going through the traps in? judging by everything else i'd say you should probably be in 3rd or just barely into 4th through the lights.

don't forget our elevation here is a killer!!!!!! cars from here that go to Dallas and run are consistently a full second quicker....no s*h*i*t*

jikelly · Apr 24, 2008

Hey Bnickel, you going to the car show in the depot district this weekend?

Yeah you guys are right about the 60 foot times. I don't know what gear I was in in the traps, probably 2nd. I think I shifted to 4th before the end. I've got video of my runs I need to get into my computer. I figure I can look at that and figure out what gear I was in and hear how the shifts sounded.

Wow! I didn't realize that Lubbock was at such a high elevation. I used to live just outside of Houston and everywhere I traveled, the state seemed very flat.
Lubbock is located at 3200ft while Dallas is at a MUCH more HP friendly 500ft.

Anyway, you have much more than a 15 second car for sure.
