Just about done w mustang

[kingranch]

Just did initial test spin on the foxbody.. got the tunerpro software hooked up to a Quarterhorse chip that is hacked into the stock A9L.

After getting turned away by multiple tuners in Houston and Central Texas bc of the new fines and crackdown by the EPA... I was forced to figure it out on my own...pretty cool to see the real-time air fuel at all rpms and make the necessary adjustments to keep her happy and healthy.

The blower is a straight cut gear si trim from vortech so she has a nice loud whistle... just had it rebuilt by vortech and they upgraded it to handle nearly 800hp.

With the sc/Anderson pipe/port polished intake/heads and cam I'm hoping to see some serious ponies when I finally dyno it.
It's got tons of go fast goodies under the hood and drivetrain lots of cobra swap stuff-

Beautiful example. If I were to pull up next to you and hear that.....not to be messed with.

That is a great looking foxbody. I remember the days when the whistle of the vortec got everyone’s attention, not to mention the classic sound with flow masters. I had a 93 coupe 5.0 that was nowhere near as clean as yours. They are fun cars, after engine work I got mine down into the high 12s and thought I really accomplished something. Now stock mustangs with the coyote run that. Again that’s a sweet car and thanks for sharing.

Thx yea It's one of the cleanest ones I've seen for a 30yr old texas car.
I got it as a roller about 6 weeks ago and have some serious sweat equity in it now-

Nice looking car. Hope you have the fuel system to go with the blower, or it will be short lived.

What is the engine combo, what crank and blower pulley? Then what does the fuel system consist of.

If it were me, I would swap the computer out for a 94/95 5.0 computer. They have a much faster operating speeds, will allow the engine to rev a lot higher before you hit the rpm limit of the computer. Even below 7000 rpm, the 94/95 computers will do a better job of controlling the fuel and spark, because of the faster operating speeds. The old fox computers are good for 400 to 500 whp. I have made a lot more than that with stock fox computers and a chip, but I would prefer to limit the fox computers to around 500 whp. When you get up around 600 whp, I would rather have a 94/95 computer. If you want something better than the 94/95 computer, step up to a Holley HP computer, preferably with a cam sensor, crank sensor and LS coils, and a unterminated Holley wiring harness. Holley's terminated harnesses are a joke, I love their computers, but hate their terminated harnesses.

Very nice!

One other thing, the Quarter Horse, is for tuning, it allows you to data log. You should not use it long term. Once a tune is created, that tune should be burned to a chip. Then that chip should be installed in the computer. To do that, you will need a chip burner and some type of chip, typically a Moats F3 V2 chip. I forgot what chip burner I use, but they are not expensive.

I put a aeromotive 340lph pump w 10an lines and some HD wires w relay

It has the 2.9 pulley on the charger but I have another bigger one in case this puts too much boost

I don't have the knowledge yet to do the ls coil swaps and computer swaps as I'm just getting my feet wet in all this.
Sure is fun to drive and pulls HARD!

[kingranch]

Yea I'm gonna tune then buy the jaybird f3 combo to get a permanent solution

[kingranch]

One issue I'm having as of now is it seems to hang a high rpm when I'm coming to a stop to downshift.... I was told the dashpot is needing adjustment but I'm not quite there yet

I saw this earlier today. IMO it is going to be challenging to get your 2 rear tires to hook up. Tons of power is nice and it needs to turn into foreward movement.
Had a truck years back that was just too light for the power plant. 60mph to 130mph was fun....................

I had a similar issue with the idle hanging high after hard acceleration. Overtime it seemed to somewhat corrects it self after learning the new idle strategy from the different cam and injectors. Adjusting the throttle position sensor voltage to just under a volt at closed throttle helped some too. I not sure if supercharged would be any different.

Take baby steps when tuning. Get your timing too aggressive, fuel too rich, or too lean, and parts will start breaking reallly quickly!!!


Boost is VERY addicting!! Just remember, spinning is not winning.



Had a 1991 Cavalier station wagon 15 years ago that was a LOT of fun, but had too much torque for the tires. Had to hit it above 60 mph or it was nothing but smoky rolling burnouts! It was a LOT of fun to tune though, and when you tune a computer yourself you really learn a lot about your combo.

Yea that's what I'm hoping bc the ecm learns as u drive so it should settle down some

Nice Fox Body.
