Okay i am kind of puzzled, when i do a burn out i get some decent rubber around 50-75 feet then is reving to high and i shift. then i try and power brake and it just about kills the motor! i will start out spinning and then apply the breaks and the motor dies out. My 92 mustang will smokem none stop! so its either my brakes are really good or my 350 built motor with only 8000 miles sucks!!

 

so has anyone had this before?

 

Maybe it's a vacuum prob?

 

what should i check for? i dont know much about the carb vacuum stuff. when the car idles it reads at around 15, then when i step on it, it goes down to to around 5 and goes up to 25 or more. does this sound normal? so you think a 350 should just bake the tires off with a little bit of a brake stand?

 

my stock 350 will burn em out without any braking thats just being honest the other day i was pulling out of the car wash and i tried giving it alittle more gas to avoid the wheel hop and they were burning out down the highway embarrassed the heck outta me cause a soccer mom had just pulled up beside me

 

any suggestions

 

" i will start out spinning and then apply the breaks and the motor dies out."

Are you saying you start spinning the tires and then hit the brakes? If so, then you're doing the power braking thing wrong. You need to hold the brake and start giving it throttle until the tires start spinning. You can let up on the brakes gradually as you push the throttle peddle down, at least until the car begins to move forward. If you give too much barke pedal, it will kill the engine.

 

its a 4 speed !!

 

LOL thats not power braking then. Its clutch dumping. Bring it up to about 3 grand and side step that sucker like you were standing on glass. If your good at it you can ease the brakes back on enough to keep the car from rolling. Then after things start to get out of hand let off the brake and the car will roll out of the burnout. If your making good power it won't move much at all and if your really making good power and got some skill you can get through all four gears in 10 feet. Leaves a nice Z pattern too.

If 3 grand don't work go higher, just don't blow it up. I like to do rolling burnouts to keep the shock on the drive train down.

 

Well the start spinning then add brake worked for my 66 Mustang but if I hit the brakes too hard I would insta kill the engine. Try not hitting the bakes as hard, you dont need dynamite stopping power to keep you from rolling forward. Also your car idles at 1500RPM with a 4speed? do you need that high of an idle because of a big cam? Most manual cars with a mild to mid level cam should idle around 600-900 RPM if everything is set properly.
