new to the boards..need some help

[Fast895ohstang]

i have an 89 5.0 hatchback with 4.10 Auburn Posi Track, AOD Shift Kit, 2100 Stall B&M torque convertor, Stock Heads and Intake Extrude Honed, B303 Ford Motor Sport Cam, 1.6 Roller Rockers, 76mm C&L Mass air calibrated for 19lbs, 19lb injectors, BBK Fenderwell Cold Air Intake, 65mm throttle body, Spintech X-pipe with High flow Cats, Spintech Side-Exit Exhaust, 1 5/8 Shortie Flowtech headers, Underdrive Pulleys, ford motorsport 9 mm wires and tweecer rt..i know for one part of my problem with the car being slow is that the cam comes in at 3500 and well the torque convertor is a 2100...doesnt match too well...that was done before i got the car and im also pretty sure that the intake mani is checkin out by the time the cam is kickin in or shortly after...i know i should prolly change the heads lookin at AFR's, i should prolly change the cam looked at isky for that im not sure tho, as for intake mani i like the bbk ssi but ive also thought about a kenne bell but dont know how much boost i could run safely without saying bye bye to the bottom end...o the reason i said the car is slow is my best time in it on 255 eagle f1 gs d3s is...
r/t .067
60' 2.298
330' 6.288
1/8 9.546
mph 75.52
1000' 12.347
1/4 14.718
mph 94.91

with 213 hp i know that number is weak for the mods but i know the car should be good for low to mid 14's if not faster...

i guess what i am asking is does anyone have any easy way other than parts swapping to get at least a safe tune on the car so that i dont have to worry about blowing it up??...lol...i know thats not funny but im really getting frustrated with the car but its freakin beautiful with the body work ive done i dont wanna give up on it

[Shorty]

nice ride. :nice: there are several Tweeker guys on here that i am sure can give you some pointers on the tuning. as far as getting faster, the AOD is not helping. really the mods you have seem to be more supporting than power building (someone may want to correct me on that statement). i dont really think 213 rwhp is too bad coming thru a auto tranny considering what mods you have. :shrug:

Welcome to the board.

I also have spintech exhaust. I'd love to hear yours.

[slvrbullit]

Welcome to the boards, that car should have a 13 in it if youcould get those 60's down in the 1.xx range. My 95 mad 214rwhp and 272rwtq and ran 13.5 with 1.8 60's back when it was virgin to the track.

[qkjuicedpony]

unless you plan on going further with your mods in the future....here is my recomendation.take the tweecer off an dgo back to the stock electronics.get an adjustable fuel pressure regulator and tune the car through base adjustments such as fuel pressure and timing....if you plan on modifying the car further just keep the tweecer and use it later.


also how about a 5 speed conversion....that will make it faster as well :D

[QWKSNKE]

Dude. You are waaaaaaaay to lean! As lean as your car is running you will probably pick up another 20 hp at the wheels, if not more, by richening it up. Get it down to where the a/f ratio is in the high 13's or lower.

qkjuiced is right, the tweecer is overkill unless you are running heads, cam, intake, or power adder

yeah but that was in a 5-speed driving it like a maniac. This is an auto car and he will probably not run better than a mid 14 without upping the power

agreed...the aod's murder a car....with a 5 speed his car should make about 250 or so as it sits

[Fast895ohstang]

im planning on adding afr heads either 165 or 185's...i want to change the cam...im lookin at isky or afm and i am lookin at either a centrifugal blower and bbk ssi or a kenne belle blower...also should i look into set of skinnies and some drag radials on dropping my 60' time a few tenths??

[qkjuicedpony]

how about this.


a set of brodix st 5.0 heads
and a cam motions cutom grind cam

i have a friend in ga with an s trim for sale right now..

[slvrbullit]

Ah i didnt read all the fine print and see that it was an Auto.

Don't the brodx heads require a lot of rpm to make power?

[qkjuicedpony]

no...you can spin them up to the rev limiter and they make good power


they work very well....you are thinking of the ST5.0 R's


the standard st5.0 heads are what was on jeffs coupe..it made 333rwhp through the stick

[Italian LX]

Dude. You are waaaaaaaay to lean!
:werd:

I bet your spark plugs are as white as my car. :eek:

i bet the white blows off his plugs just like the paint on your car too :D

I'm going to totally disagree with the removing tweecer and tuning with a APFR.

Use the tweecer to get the a/f down to ~13 or so as recommended. Base OL fuel table.
Using the aformentioned idea will make adaptive remove the FP adjustments.
Or you could just turn adaptive off an run a certain FP,, this is counter productive in my eye as you have a great tool (tweecer) that you are just not using it's potential.

[Italian LX]

:agree:

I preach this all the time, but some peoiple just refuse to listen. :rolleyes:

Fuel pressure adjustments are good for getting better spray paterns (by increasing pressure); however, they suck at changing A/F ratios for more than a day ar two.

[coupe]

The stock heads and , yes the intake, are limiting the camshaft so that might be a starting point since it's all on the top of the engine.

But I really think you are having a bad case of the AOD blues. I would look into a new, quality valve-body and a 3k RPM stall convertor (I think it's the stallion that works so well). I would bet a stall and an AOD tuneup would get you into the 13's. IT will LOVE those 4.10's. :yup:

I would agree.

I had a '91 GT convertible with an AOD. The only mods were 3.55 gears, shift-kit, 3-chamber flows (weld-in), underdrive pulleys and ram-air. With those mods, it ran consistently 14.6 on street tires.

You should definitely be closer to 13's... if not in them already.

:think: then according to this, mine should be capable of 13's. :shrug:

It has to be on the track first. . . and you need to learn how to drive it. :poke:

[indy2000]

:eek2: Is just me and Qwksnke that sees over 15:1 a/f,,,,,,


That's why the power is down. Great for smog but not power.

:yup: i will be very anxious (sp?) to see what i can make it do with a good set of tires. i have only made 4 runs in it and moved from 16.1 to 14.7....so that is some improvement. although those times still bite.

:jester:

[Fast895ohstang]

the af needs to be changed...i know that and my torque convertor doesnt match the cam at all....the stall speed should be just a lil above when the cam comes in for it to run right otherwise its gonna run like a dog am i right??

[QWKSNKE]

get the a/f fixed before you start worrying about the converter

[93Cobra#2771]

The dyno operator needs to have their ass kicked - any time they see an a/f like that, they better be telling someone to get off the throttle. That would piss me off to no end if a dyno operator let my car go to 17:1 and didn't even tell me to abort the run.

I would make mention of that next time around.

And don't dump the tweecer - just undo whatever mods you did to the fuel tables... :D
