Sure, you can do a burnout. Break something? There's always a risk. If you're worried, don't do it, plain & simple.

 

 

Burnouts are easy if you've got mods. Stock, the 2.8 is a little anemic but if it's in pretty good shape it can hold a powerbrake I'm sure....just be careful. It's bad on the brake drums, bad on the engine (if you keep it in first gear it revs up), tranny (not so bad as long as it's held in first), torque converter, you name it! Not fun..I gave up months ago.

 

ya man u can do it!lol.... i can do burnouts easy with my 6 well since i modded it.

 

Just be sure to Powerbrake it and not PowerBREAK it....

 

What mods would you perfur me to get?

 

Straight off the bat...it is not cost effective to build these motors at all. If you're going to build a 6 in a thirdgen F-body, swap in a 3.4. But if you are insistent on building your six, do a major tuneup..TomP's the master on that one. Get your ignition all straightened out and any repairs that need to be done. Then do intake and exhaust. Do some home depot homemade intake work or get a dual snorkel setup, throw some K&N's in, cut the things off on the bottom..there are several ways to go about intake. Exhaust, I recommend the Dynomax Super Turbo catback. It's 2.5 in., adds a lot of power and isn't too loud, it's very deep though...it's like $160. Pipe through the converter or replace it with a high flow and you're in business.

 

Yeah its easy i used to have a 88 2.8 only had like 60k on it and it did killer powerbrakes, i did one on the last day of high school there was so much smoke you couldnt see the car

 

Gta guy did you have mods or was it stock? and when you smoke tires did both back wons spin or just one of them?? both spin if wheel strait right?

 

yeah i had a few mods, flowmaster exhaust, KN filter, accel super coil thats about it, only one tire spun at first but when you really get them going they both do the left one just spins a little the right one makes all the smoke


Theres a pic of my old car, I still have it its FOR SALE

 

Nice car..Oh i c thinks for you help..I am getting pics of my firebird soon.!

 

Wow...that is the most beautiful bird I've ever seen, hands down! But it's only a 2.8? But still....DAMN..nice body work!

 

got a question about the open rear end. does the
left wheel ever get power to it or is it gust the right all the time.

 

it gets some power once in a while not a whole lot though

 

Ice bird what mods you got? pics?

 

i did not do to much but when i did it there was a huge diffrence for me. a just got a 2 and a half" catback, high flow converter, flowmaster muffler, and custom y pipe. i made a cai but i dont think that does anything when brakeburning otherwise it help a bit. not much i no but trust me it makes a good diffrence.

 

It will be only the right side 99.999% of the time.

 

Yep...except in reverse. Reverse drives the left tire.

 

its deffinitly possible to power brake a 2.8 its lots of fun too. i can peel them all day in my bird with no problems. mind you though that my bird is heavily modified. i have seen a stock 2.8 maro power brake too. it didnt seem to have a problem doing it.

 

No doubt a 2.8, in stock form, is very capable of doing one.. Just the older, high mileage, tired 2.8's can't always do it.

 

Wow, that car is beautiful.

 

I would not do a burnout for the simple fact that you run the risk of breaking something just to look cool. I like peel outs though. I have trouble enough doing those, especially with a tired engine. My low end is bad unless I apply more than 50% throttle, but I have some decent power in the 3500-5000 rpm band.

 

If I give it 3/4 to full throttle from an idle, at standstill, I can peel out nicely.

 

Hey I was wondering about my drive train. Ok first off did they ever make any thirdgen 2.8 posi track rearend? Second i was wondering if my car was posi...because i was out in my drive way with my brother and i was just playing with the gravel i was spinning out well you saidd 99.9999 of the time your left tire spends or right whatever one it is well my both of mine spunn .and i did this many times..never had just one spin. then i put my car up on the ramps so i could change my oil..i dug two holes because of the gravel....both spun there? whats this mean? mine spins 50/50? have sombody put posi on it?

 

my 3.1 with ~25k mls spins the tires very easily. i don't even have to floor it, 1/2 throttle is enough

 

Gravel is very low-friction...a non-drivetire spin is very possible on gravel. A simple test if...if you ever get your car up on a lift, where the rear tires are physically off of the ground, grab one of your tires and spin it...if you have an open differential, the other tire will spin the opposite direction. POSI won't do this.

 

well first off I have a manual.
If I "power up" 2-2500 RPMS, then hammer the clutch(not drop it-just release too quickly) I can easily spin 1st, and halyway through 2nd.
Before I put on a high flow cat, I used to go through 1st, 2nd, and into 3rd.

 

So then take the high flow cat off, put a normal cat back on, and quitcherbitchin'.

The posi test mentioned (jack car up, spin tire, watch direction of opposite tire) will only work on a posi that's not worn out... true "posi" test is to drop the rear cover and take a look inside. You can also try getting the axle code off the axle tube (faces FORWARD, on center of passenger's side axle tube), and looking it up, to see if it's a posi axle (from the factory). But the only way to tell if someone added a posi is to take the rear cover off.

 

So your saying that if you look at axle i can tell by the code..if i get that code can any of you tell me? if its posi or not? or do i have to like call gm or anything?

 

The codes are listed in the Haynes 82-92 Firebird book. For 82-84's, the codes are in the rear axle section. For 85-92's, the codes are in the last section, the "85-92 update" section. But the best way to check is to yank the rear cover.
