im almost embarresed with posting results, but screw it. i wasnt expecting anything good.
best 60' on 26x11.50/15 @ 12psi was 2.35
best 1/4 mile was 17.24 @ 77
car bogged really bad with those tires. my car is stock, sides an HO intake, and 19# injectors on a 130,000 mile 302. nest time i go to the track ill have an electric fan, 3g alternator, longtubes, t5, and bullet lers. ;)
a gear would help alot . maybe a 4.10-4.30 .
good luck next time takes a while to get them right:)
the t5 swap will help alot too...and just rin the street tires...id be willing to bet you dont realy need a drag tire or whatever you had on there....i bet you drop a good second....
well i did a little weight reduction this week. i pulled the front bumper, supports, front swaybar, spare tire, pass. seat, air silencer, and put the stock airbox back on. i did add a taurus electric fan today, too. the 1st pass was a 16.6 @ 81. 2nd one, was a 16.5 @ 81.45mph, on street tires. i didnt really feel them spin either.
the aod is still slipping just a tad on the 3-4 shift. im gonna do a tranny flush, swap my eec to an A9P(already have the mass air meter), and find some 4 cyl mustang 3.45 gears. that should get me in the low 15's/high 14's. LOL!
i was gonna put on my exhaust, but the car wouldnt pass inspection, due to the high beams not staying on. :bs: they were working fine on the way to the track though. :rolleyes: i wanted to wait on swapping exhaust, till after i could get it inspected. oh well, there's always next week.:D
You still running the SO cam??? What EEC now???
Looks like you made a good improvement for the mods you have.
still running the factory speed density cam, and computer. i thought about buying/borrowing a timing light, to see what it's set at, but couldnt get one in time. ill put some 93 in the tank, and try bumping the timing up quite a bit.
i have a couple of friends "donating" parts, to get me a little quicker. one has a set of stock mustang trw forged pistons. another has a set of home ported E7's. and another has some stock trickflow vavle springs, that have never been used. :D i picked up an "E" cam the other night for $50 :eek: , also. i was gonna wait till i converted to mass-air, before putting it in.
i should have a pretty quick t-bird, within the next couple of months.
spiffy I want in
Good luck with it man, you should pick up noticably with those parts. What altitude was the track you were running at and what temps? My 'bird went 16.45's when it was still bone stock, the temps were in the low 70's and the DA was around 4ft above sea level.
:D now I don't feel so bad that my completely stock 20th anny ran an 18.1 et.;)
So you are running 19lb inj on a stock Tbird EEC and cam???
I'm suprised it runs as well as it does... It's got to be way to rich...
it is :rolleyes: , and probably why my idle bounces after the motor warms up.
*Update*
got the bird converted to mass air and a t5 now. :D
took it out to the track, the day i got it in(thurs), and clicked off a 14.8 @ 92mph. i had ran it with the mass air and AOD before, but only got a 16.5. i was on street tires both times at the track.
after christmas, ill get an 8.8", slicks, and some 3.55's or 3.73's. ill post back with more results. havent fogotten about youse guys!
Congrats on the 14s, you still have the stock Tbird cam???
What was the 60ft time???
yes, and a 2.234 60'. with just slicks, i should be able to get a 13.9 out of it, the way it sits. that's if my stock axles will survive some 4,000rpm launches. ;)
Well I'd say thats a bit optimistic... With maybe a 1.85-1.95 60ft, I'd think more like a 14.1-14.2...
Interesting to see it runs as well as it does on the SO cam... Prolly pick up a good bit with some 1.7 roller rockers...
You'd be suprised to see what stock axles can do. My buddy was driving to 12.0's every week with 5,000rpm clutch dumps. Another buddy of mine went 11.76's for almost 2 years before destroying his spiders...but his car was an auto.
How do you have the wires for the injectors? are they still stock, or did you move them back over the stock firing order?
the car also weighs 3150# w/ driver ;)
never messed with the wiring. you DON NOT have to change the routing of the injectors.
... My fat girl weighs about 3500(plus 190 or so for me), but I have dual power seats, working AC, pot belly, etc...:rollin:
i still have a driver side power seat, AC, power steering, smog pump.......my car isnt really gutted.
on to another chapter.......
ive got the 8.8" in w/ 3.55 gears, 15 x 8 telstars, and BFG drag radials. my 1st pass last night was a 9.36 @ 70mph in the 1/8th. 60' was a 1.9. i launched the car at 3,500. the car bogged real bad after the launch.
2nd pass, i launched at 4,500. 60' was 1.871. bogged again, but did a 9.359 @ 75mph.
3rd and final pass was made on a 5,000 rpm launch! 60' was a 1.99. car will not rev past 4,500 now. ran a 17.7 @ 70mph.
something isnt right with the motor, and ill be tearing into it tomorrow. if its something minor, ill be back at the track friday. this time ill launch off idle, so it wont bog the motor down.
something broke, top end it sounds like to me. decent 60' times though. keep it up and let us know.
im not sure if anything broke, but the problem seems to come and go. it seems that when the engine is under a load, the problem will come back. i can free rev in neutral, or do a burnout, without it cutting out. but as soon as i put it in gear and drive it, it will cutout around 4,000 rpms.
Sounds like the exact same thing my car is doing. I believe it's my fuel pump/strainer. When I'm low on gas and go around a corner hard while i'm on it...it will get even worse but only at about 4,000rpm. I don't know, I have a spare Walboro 190lph pump so why not try it I guess. Let me know what you find with it...I probably won't get to mine for a while.
Good luck!

fuel pressure at WOT is 41psi, and 32 psi at idle. so i dont think its a fuel pressure issue. alos the car idle a little rough.
I think you should throw in a mustang mass air computer, I'll bet that would help with the bogging down at the higher end. Maybe dirty fuel injectors?
i do. ;) i have an A9L and autologic chip. along with a stock mustang mass-air meter, HO upper intake manifold, stock mustang t/b, and 19# injectors. still using the stock t-bird cam though.
Try cleaning the MAF?
okay...thought the a9l has the HO fireing order...did you just move the plugs around? i didnt realy think the stock SO cam and heads would benifit from MAF. could be whats keeping your car running okay with the 19lb injectors...
you dont have to re-route anything, per eric's site. the car ran very smooth after the conversion.
ive already cleaned the MAF with brake cleaner. ive swapped computers, MAF sensor, BAP sensor, TPS, cleaned IAC, used jumper cables for additional grounds, checked/adjusted timing, checked for broken valve springs, replaced plugs, replaced coil. im gonna buy a new cap and rotor today for shiznits n' giggles. after that, i dunno what else to check.
Basically, his point is, the SO and HO use different firing orders, and that there is no MAF computer for the SO firing order, which is determined by the camshaft.
which im aware of. are you saying it wont ever run right, unless i get an HO cam?
I have no experience with it personally, but that could be where youre losing major power.
If that is the case, a stock HO cam with some 1.6 roller rockers should help you out.
No, you can swap the wires that go into the plug for your computer harness. The number 3,7,2,6 cylinders fire in basically reverse order on the SO cam. I don't remember which pins you have to move off-hand....anyone else out there that made the swap and can remember?
Basically each cylinder will have it's own wire that goes into the plug for the computer and you have to swap those four cylinders. If no one else has the information handy, I will try to find my documentation tonight when I get home.
FWIW, back when I was in high school (95ish) I took my stock 84 Bird 5.0 to Bunker HIll, IN (1/8th) and I ran like a 10.8 or so...
went back to the track last night. all these times were on a 125 wet shot with 14 degrees of timing and shifting at 5,400 rpms.

i dont think that's too bad for a stock motor that runs a little rough. :D
As others have said, you cannot simply use an HO setup (injectors, computer) without doing 1 of two things:
1. Rewire your engine harness to make the injectors fire in the correct order of the SO.
2. Replace the SO camshaft to an HO (such as the E cam you bought).
If you're still using the SO cam, your computer is squirting half the injectors at the wrong times in correlation to the intake valve and firing order of the distributor. Rewiring the injectors will put it back into sync with the cam and firing order, but then you'll have to switch the wiring back once you install an HO cam (like the E cam you picked up). Better off just installing the cam the first time around....
Joe, swapping the inj order actually causes more problem than leaving them in the SO order. Reason??? #1 fires... o2 senso reports back to EEC all is well., Now #3 fires BUT the EEC is thinking it is firing #5 and is looking for a responce from the o2 sensor... Nothing. OK I richen it up next time... still nothing(remember 3 & 5 are on oppisite banks)... BUT its getting a signal from #3 that it is too rich, OK I'll pull some fuel.... no responce... So what eventually happens is two of the switched cylinders wind up too rich and the other two are too lean. Leaving it as is, the EEC does adapt to the slightly uneven mixture caused by wrong firing order...
