Today i put my timming 8* advanced. and let me tell you!! My car is crazy.. i can do burn outs like crazy and accelerate like no tomorrow. I love it. I took my friend in it and after i was done showing what my car can do, he was shacking.. I love it!!:lala: :hail:

 

advancing the timing does wonders, my freinds highly modded 350 ran like crap until he advanced the timing to 8*

hasn't lost a race in it since

 

its weird how a little thing can make a big thing so great im so excited about it, feels like no one can beat me.

 

I'm sure this is posted somewhere on here, but I'm too lazy to look right now.

How do you advance your timing, and how much should you do it?

I have a 1992 Camaro RS V8 305TBI

 

My car is down an easy 100hp when the timing is retarded. Its as if im running a 2 barrel carb. 34-38 degrees total seems to be the magic number

i dont think you want to retared your timming. I think it makes it worse for you.

 

im not checking my knocks after i did my timming. but i cant hear anything. my car seem to like what i did to it. what will happen if it is knocking and i leave it like that?

 

in all honesty, nothing

I had a beater with as messed up ecm and it would knock constantly. I drove the **** out of it for 200k miles and it was fine.

In theory if your running nitrous and it knocks it'll blow the engine.

 

IMO advancing the timing is the best free mod you can do. these cars are incredibly responsive to it. if you have a DIY prom you can do that in the spark advance table but if not you can accomplish about the same result the ol skool way. i had a few knock counts at WOT but nothing significant and the difference is simply amazing. another great cheapo mod was the the throttle body coolant bypass. it cost me about $5 and SOTP dyno said it gave me about 20hp depending on the weather. with that, a k&n, airfoil and 3" exhaust i ran a 102 trap on a bone stock engine.

 

What was your timing previously set at? I'm interested in how much you advanced it. Thanks, Allen

 

could i have any luck doing that with a v6 2.8? "advancing the timing"

 

Yes it will help on the 2.8.

 

Its weird i hear people saying that they have trouble doing burnouts and stuff but i just get on it alittle bit power bracked then let off and she spins a good 3-4 sec coming out of it like its not having trouble it all its weird.

How would i go about adjusting it on a Fi 2.8

 

 

Wow. Next thing you know, people will start changing their oil, changing their fuel filters, spark plugs, plug wires...

 

LMAO

 

"Knocking" is usually the sign of an uncontrolled detonation of the fuel in the engine or a sign that the spark plug is firing while the piston is trying to come back up to Top Dead Center. Basically meaning the power of the explosion in the cylinder is now trying to make the engine rotate backwards. Usually bad things can come of this like burnt valves, broken rings, burnt pistons, pistons with holes in them, snapped crankshafts, broken connecting rods, and generally things flying out that should stay in, in extreme or prolonged cases. Nitrous or no nitrous.

What causes these is:
Overheating of the engine
Timing problems
Use of a lower octane fuel
Improper use of nitrous

Now, keep the octane ratings in mind. If you used to switch from like regular to premium once and a while, you may have to use premium all the time now. This is due to the fact that the higher the octane rating in gasoline, the SLOWER it burns.

Hope this helps, and rock on with your newfound smokey burnoutedness.

 

Next time you race try and run with about a 1/4 tank of gas. The car will feel much faster. It saves like 150lbs of weight or somthing...

Oh, check your tire pressure too!

 

I take it people just don't read the tech articles or browse the boards anymore, they just come on to post ala Shane.



Max, you mean I have to change that stuff?!? WTF! No one told me that!!

 

Can this be done on a 92 'Bird 305TBI?

My buddy has one and when I reccomended doing it(it runs 15.3s now with some mods) he said it was all electronically controlled and you couldn't manually change it? Is he right?

I have an old 81 and the closest thing to electronics is the radio so I just shrugged my shoulders and said okay when he told me. Whats a good, conservative baseline to set it at-6* or so?

 

your pistons will melt.

 

Gasoline only weighs ~6lbs/gallon, so I don't think 150lbs is right.

AAMOF, with the dinky gas tanks we have, running 1/4 tank instead of a full tank would be ~60lbs less. That's not even enough to make good use of the 10lbs/.1 second rule of thumb.

The 60lbs would probably be better for traction. Plus you wouldn't have to push your car home at the end of the night, unless you break something that is.

Yes and no.

The computer does control the timing, but it uses the stock base timing as a refference point. For instance..... a stock LO3 has a base timing of 0* BTDC. Then the timing table follows that.

If you move the base timing to 4* BTDC, everything in the timing table will automatically have 4* timing added to it, as long as the engine doesn't knock. If the knock sensor kicks in IIRC, the timing table is retarded up to 20* to get rid of the knock. That's quite a loss.

And believe me, the knock sensor will know if the engine is knocking, retard the timing, and slow the car down WAY before you'll be able to hear it.

 

Are muffler bearings on my buddy Bosephus' car adjustable to 20 BTDC?

 

only if you change the headlight fluid for halogen..

 

Is Blinker fluid the same as Headlight fluid? Or will I have to make two trips to the store?

 

Thanks for the help AJ. So bring it to the track? Give it 2 degrees until it slows down and then retard it back 2 degrees? Sounds easy enough! I know its quite a shot in the dark, but how much you think this will be worth on a 15.3 305TBI? Enough to sneak into the 14s?

 

Just look at your user name for your answer, grasshoppa.

IUNNO.

- Bosephus' friend

 

There's only one way to find out.

 

You should use that quote to sell the "kits" on ebay. lol

 

I don't know how to set my timing.

I just add it in the chip

Kat

 

I sense something is retarded, but it's not your timing

 

No, unfortunately the Pontiacs didn't have this option You can only adjust the timing on a Camaro.

 

believe me i've thought about it but it isnt a high enough priced item to be worth my while. so just go to the hardware store and but the little plastic coupler and maybe replace your hose clamps if you need to. it's less than $5 actually. but seriously, i literally checked my MAT before and after and it dropped the intake air temp by 80 degrees! that is, until the plenum heat soaks...

 

I was kind of insulted by your remark until I noticed you were from the valore suit capital of the USA-Staten Island-then it made a lot more sense...I'm sorry.

And stop trying to imply you are part of NYC with your username. While it may "technically" be one of the five boroughs, just about every Staten Islander I've met would rather succede from the City of New York(as was attempted in the early 90s unsuccessfully).


I'm just messing with ya don't take me seriously. I can take it too!

As I mentioned before my knowledge of electronics is limited seeing as I have a big-loud-carbed-solid cammed-no electronics but an MSD box 81' Camaro. Just going by what my friend told me. But I admit I expected a few smart a$$ remarks!!

 

it's called sarcasm, look it up

 

No wonder Firebirds suck, and i thought they were the luxurious version.
