Ok so my mustang I have is a 88 5.0 with auto tranny and stock freeway rear gears. The guy I bought it from was the original owner and he told me stories how he would just light up the tires on her all the time when he was a kid. The motor and tranny are relatively new only 20k miles on them but the rest of the car is pushing the 150k mark. Now maybe this guy was feeding me ******** idk but I would assume a car with this motor should be able to at least break the rear tires free for a lil bit and it doesn't yet I'm slowing getting it closer to burnout status but it's just not quite there. When I got the car lots were wrong with it. Although the motor and tranny are new all the bolt-on's were original so I had to swap out the alt, dizzy, water pump, harmonic balancer, fan clutch, and sensors, changed out all fluids even the diff has fresh royal purple in her. I have not yet tackeled the motor mounts which look destroyed but motor doesn't seem to move and I just ordered a complete tubular control arm and bushing kit for the rear.

So long post shortened up. Could the lack of ability of burning out be due to the bad motor mounts and rear end bushings being 150k miles old and all sloppy? Or did the guy feed me some BS and with the rear end being stock freeway gears there's no way to get a healthy burnout without a power brake method.

As for performance upgrades done so far I have a gt40 intake, 70mm tb, 70mm MAF, K&N filter, headers, and flowmasters, ignition upgrades.

About to install tubular control arms rear and motor mounts

What would be the best next step after this? Thinking of tranny shift kit (kit or new valve body?), rear gears, or ????

I'm still running my stock rims due to them being special mclaren rims so they are just simple 15 inch 4 lug 6in wide rims nothing hella beasty to be limiting her ability to break them loose.

I am asking this not because I wanna go around burning out everywhere it's more me tryn to get this gal back to her normal self. And I'm basing this all off the previous owners statement that she use to burnout on demand. My thought is seeing how she's not doing that there still must be something wrong with her.

Thanks for your time on this silly matter

How sticky are your tires? Air pressure? How does the car accelerate, other than not breaking the tires loose? Many of us try hard to prevent wheel spin. Let's try to determine if you have a problem before you spend a lot of dough.

Tires are old like 10 year old tires nothing special probably only H rated if that car runs very strong very very fast on freeway. When it's wet yeah she will spin for days and on dry pavement it will occasionally break loose but it's a rarity I almost always have to be turning left or right for it to happen tryn to have it happen stright off the line it just goes no cherp nothing.

Would motor mounts and sloppy rear end bushings be a factor though my assumption is I'm losing just enough rwhp/t in the slop to prevent the needed power to the ground to cause easy burnouts.

As a comparison I had a lead sled 96 impala SS and the motor had the same hp and less torque and way more weight even with a full 25 gallon gas tank the car would burn out on command. The mustang has more torque and less weight and thinner tires and a shorter wheel base than my impala had so why is she being so stubborn lol

You don't have more torque than a 96 Impala SS, not with the bolt ons you have. I see no mention of a cam swap so you'd be lucky to be pushing 260-270HP at the flywheel, cut that down to the 220's after the automatic trans, not exactly blistering power especially with an auto. 2.73 gearing really does not help at all, put some 3.73's or even 4.10's in and you'll be buying tires every month.

I have the opposite problem, no traction in the first 3 gears, at 30MPH it'll easily spin the dried out old ass tires I have. Of course I have a 5spd so that helps, but you're gonna have to do some real modding if you want to spin them at will.

Well darn lol I was thinking of only going to 3.55 gears I wanna keep some top end for freeway driving... i do plan on swapping out the stock heads and cam I just need to figure out what would be best for my cali car seeing how i still have to pass smog here. Not sure what's out there besides some explorer heads and a mild cam but I've even been told that can put me over the smog limits here...

How does the motor run? Sounds like you've done a lot of work, but how's she run now? Where is your timing at?

If the motor is running well and still can't do a brake stand, you might want to check your rear end and diff. If the previous owner was doing some burnouts and brakestands, probably wore out the clutches and need to be rebuilt.

There's a thousand things that could be wrong so I'm not going to try to internet-diagnose it. What I will do is confirm that something is definitely wrong. My 87 is completely stock and it is a burnout machine, 2.73 gears and all. Just start with simple stuff like checking your timing. Good luck!

He has an auto, much more difficult to burn rubber than in a stick.

Are you talking about dumping the clutch? I never dump the clutch; too hard on equipment. If I'm in first or second gear(which is pretty high with 2.73's), I can just floor it, step on the brake, and it'll roast 'em all day long. Or go about 15mph, floor it and yank the wheel a little and it'll instantly start doing donuts. Other mustangs don't do this too?

There is something wrong. You should be able to burnout regardless of tranny.

Clogged cats? Timing issue?

Have you run codes to see if it pulls anything up?
