Automatic Guys Help

[casperfast]

ok, i searched and couldnt find this.(95 tsi, 14b turbo, automatic,fmic, intake)
im sitin at a light or stop sign or anywhere and i take off normally, slow cars great after it shifts to second and i floor it, kicks down takes off fine. BUT!!!! if i give it some stick from a stop at maybee 10-15 mph it goes pop and jerks, under almost no boost. WTF is going on here?

 

[lilbro717]

huh, im alittle confused. whats happening when?

 

[casperfast]

basically at low speed under aound 50% or more throttle my car pops, or back fires sorta, and jerks

 

[casperfast]

i also wanted to know, how tough is the 2g automatic trans? can it handle a neutral drop?

i also wanted to know, how tough is the 2g automatic trans? can it handle a neutral drop?

is it completly stock, if so, not too well, i no my friend did that and broke his diff. but y would u want to do that anyways?

 

[casperfast]

i was just wondering how tough they were. any ideas on my motor problem?

Is there something you'd like to share about neutral dropping experiences?
Neutral drop gets you no where quick.

Neutral drops kill tannies. You have an auto use it. Brake torque, hit the brakes then the give it gas for a few seconds to build boost then lift off the brakes and go. It works pretty well.

About your original issues if you could better explain your issue, I can't really tell what you're asking.

Backfiring under boost at moderate RPM is a normal symptom of running too rich. Unburned fuel is reaching the hot exhaust manifold and "popping" off.

Running too rich is a normal symptom of a boost leak. If the condition is more pronounced under part throttle then the leak is more likely upstream of the throttle plate.

Don't neutral drop until you are really tired of your transmission and need a good excuse for a new one. Power brake if you feel the need for a hard launch, and then change the ATF regularly.

if you want to upgrade ## tranny, look at IPT, they did my tranny

 

[casperfast]

i havent done any neutral drops. i was just saying that as a comparison for how strong is the tranny. so too rich, and a boost leak. got it. ill check it out. thanks!!!!!!!.

Where is the backfiring coming from? I'd check your timing and make sure it's dead on. Also check the tension on your timing belt.
Most of my experience is with large v8's and diesels. Any time you have a backfire in the intake side of the motor it's a timing issue, exaust backfiring could be either fuel or timing or a combination. Need more info for a diagnosis.

 

[casperfast]

the blts right. the timming is not adjustable on mine. sounds like exhaust

 

[knochgoon24]

It's not "adjustible" per se but it can jump a tooth. It's not too hard to check.

 

[casperfast]

i know it didnt jump a tooth. if im going 35 mph and i put the pedal to the floor it takes off perfectly. as long as i dont push it at low speeds it runs fine

 

[vaboys2ndgen]

how much boost are you pushing on that 14B?

last setup when my car saw the street 2yrs ago

14b
evo8 fuel pump
550cc injectors
20psi
3" turboback
3" intake pipe
fmic
shift kit, trans cooler, trans temp gauge

def gotta watch the boost level, due to running out of fuel (my thoughts were fuel cut) but without actually hearing or seeing it in person not 100%.

 

[casperfast]

i am positive its not fuel cut. only 13psi right now, i can set it wherever. ive hit fuel cut. only happens if i crank it up to about 17 psi or more. this is under like 5psi or less, low speed only
