Track test

[mitymerc]

1st time @ the track w/the 4.10's & Tracloc....

All passes w/shifter in OD

3.27 1/8 Avg over 3 passes:

60' 2.61

ET 11.50

MPH 61.96

I did make 1 pass w/ shifter in 1, manually shifted to two & it immediately shifted to 3rd.

60' 2.59, ET 10.48, MPH 65.50
================================================== ======

4.10 1/8 mile, Avg over 5 passes:

60' 2.49

ET 10.78

MPH 64.44

================================================== =======

Avg difference:

60' .012

ET .720

MPH 2.48

================================================== ========

The air was much better today the DA was 2809' last time vs 1766' this time.

================================================== ========

Looking back to the last time out, when manually shifting it picked up 1.02 seconds.

I can't wait to test it w/the Mustang 'verter & Transgo shift/high rev kit!!!!

first off congrats on the gains pretty nice. H.O. or lopo? This is interesting to compare with mine. H.O. swap, mass air conversion, 70mm mass air meter, electric fans, no A/C or smog, mustang tranny, and 3.08 gears. The interesting thing is the 60' and the mph.
I 60' 2.5 every time almost and run 11.80's at 65 mph. Now I know with a lower gear your e.t. will be faster and your mph will stay almost the same. But I would have thought the 60' would have improved more with the gear, are you spinning off the line. How are you launching off idle and stomping it or stalling it off the foot brake? Sorry if you hate me for the long post I just find comparisons like this very interesting , you really make me want a set of 4.30's for mine till I get the new engine ready haha.

[1980c10]

I mean 10.80's not 11.80's brain fart haha
I beleive if I went with 4.30's and a better exhaust I would have my self a 9.50 car, and thats usually what a stock auto mustang runs haha

[mitymerc]

87 C.V Wagon, stock bottom end, GT-40X heads, 1.7 rockers, stock '88 Mustang H.O. cam (not enough clearance for any more lift), Explorer intake & T-body, bored EGR, 1 5/8", shorties , 2.5" X-pipe, single chamber Thunderbolts, 2.5" full length tails, stock '88 H.O. SD comp, stock (slightly messed up) '89 E-150 AOD, Mustang Tracloc w/extra clutches packed in it, FRPP 4:10's, I think that's everything....

The only things different from last time out & today were the air & the T-loc/gears.

Dead stock it ran (over 4 passes)

60' 2.52

ET 11.85

MPH 56.61

DA 3445.

I have no tach, so I just footbrake it, give it some gas, then punch it when the tree comes down....

Today, the guy in the water box, as every other time, brushed all the standing water off the burnout area, & I drove through the damp spot & punched it (295/60 BFG's) Usually, it just drives out, today it would pull/chirp/pull/chirp, when the damp part of the tire hit the the track it would chirp.

It doesn't have enough grunt to do a real burnout dry & I'm not going to put full tread street tires in the water!!! As far as spinning off the line, It may have, I didn't feel it as I'm used to a stick car that 60's 1.6/1.7 depending on conditions....

You got me thinking about my '91 GM wagon, stock Mark VII LSC 5.0, SD '87 computer stock Mustang headers, stock Mustang cat pipe w/2 stock cats & a combo of 2" & 2.5" pipes, 2 chamb Thunderbolts, t-lock, 3.55's on cheapo 225/70's. All Junkyard parts (including the engine).

It does HAIRY burnouts!!!

I just reviewed the log book it runs 2.33 60's, 10.63 ET's & 65 MPH in WORSE air (DA 3159).

I am now Dissappointed in the Crown Vic!!!!

BTW the Grand Marq is for sale.......

[mitymerc]

How do you do your:

Burnout?

Launch?

[1980c10]

I dont do a burnout, and I have stock trac-loc with the 3.08's so I cant really get it to spin the tires if im holding the brake down hard, im running the stock size 215/70/15 white wall cheapo tires on turbines btw. So i just roll past the water box get staged and as soon as the other guy gets staged I push down the brake hard and hold the gas to the floor, then on the 3rd yellow release the brake and away we go haha. Dont be Dissapointed in your car im sure i have a fairly reasonable weight advantage over you do you know how much yours weighs, mine is 3900 and some change without me in it and a quarter tank.

Thanks for the burnout info.

I was comparing my Grand Marq wagon to my Crown Vic wagon.

I think the Grand marq was 4300 w/me & my 10 year old in it....

[ironstealth]

Not too bad,I'm picking up my 4.10's today. I'm a little confused on your times,with all the work I think it should be faster.
HO intake and duals I ran 60' 2.41
1/8-11.08
1/8mph-62.48
That was with a 2.73 open,bald original tires,3 ton craftsman jack and tools in the trunk. Full interior,ac and smog in there too.
We won't talk about what its running now....

[mrltd]

It doesn't have enough grunt to do a burnout? My stock lopo with a 3.73 and track loc would roach the tires.... ( also wagon)

I'm surprised the 60's aren't better with the amount of gear you have. But you have a stock trans and converter, so that's really hurting your launch.

[1980c10]

I could do a good burnout with the lopo as soon as I start power braking it they would cut loose and now with the H.O. It will do it but it starts off very very slow untill it builds into the powerband then it really cuts loose but it takes forever to get it going even with the lightest brake pressure I can apply and still hold the car back.

[mitymerc]

I'm a little confused on your times,with all the work I think it should be faster.

Yeah, I'm confused too LOL..... w/the 3.27's it went 10.48 when shifted manually...all the times in the averages are w/shifter in OD.

The Trac-loc is a fresh rebuild w/extra clutches packed tight.

It has heavy aftermarket wheels and 275/60's so that kills the gear a little.
If I got em wet, it would do a burn out, but I'm not dragging all that water up to the line!
It doesn't seem to be spinning on launch.

There is something goofy about the trans though, It slips occasionally & sometimes freewheels on the down shift.

The car also seems to shake as if it is being held back at lower rpms, I hope the new (used) tranny fixes that....

The '91 G.M. C.P. does hellacious burnouts, if I can find a pic I'll post it....

That was with a 2.73

Does you even shift to 2nd in the 1/8 LOL My 2.73 mustang didn't have 2nd wound out by the time it got to the traps...

On the 10.48 pass I held 1st to between the 330 & 594 marks w/the 3.27's.....

[mrltd]

you have to manually shift, without a shift kit/HO governor the trans shifts before you make peak power.

yeah,1st ends at about 52,i made three passes,one with manually holding L gear,threw it into drive,it wasn't too much faster so i kept it in drive(not OD) and ofcourse heated the tires and loaded the brake,and launched. Now it seems that short shifting it is the way to go. I lay on it in first,and at about 45,i blip the throttle to hit second at wot. If you arent fast enough,you will go into 3rd and completely miss 2nd gear,then you're not really going anywhere. But 4.10's should be in next week or so...I still got a little time to run down the track before the snow comes.
