This is basically in a nutshell what happened in your motor when you rolled into boost...
03-19-2011
Do you have a scan gauge or anything to monitor whats happening? You may want to pull your plugs and check them. When mine did that I found this beauty.

Whoa!!! way to small of a pulley. These cars knock in stock form. I wouldn't be surprized if u exploded piston #3
03-19-2011
Thats what happens when you have high boost, high RPM's and not enough fuel.
Now only that but I managed to essentially melt the compression rings.
That was on a 93 TSi I once had.

This.....did you even scan after the pulley drop...where you knocking with the previous pulley?Originally Posted by 99prixgt

i can roll into the boost without a problem just when i smash the pedal is when it hesitates... i checked vaccum lines and the plugs looked fine but going to replace them and wires... and possibly coil packs... no one seems to have a straight answer i been looking on various forums... i don't have a scanner...

Straight answer, your knockin like a mormon missionary. You don't have the mods to run that pully. Its going to blow up. Put a bigger pulley on and then sort your issue before you do more damage. Then read the thread about safetly modding you 3800 that I'm sure some one will link
03-19-2011
Yes we have a clear answer your running way to small of a pulley without being able to scan... I wouldn't run anything lower than stock without a way to scan the car for knock.....we are trying to help you not chip a bank of pistons....I've been around the GPbworld for 10 years now, I think I've seen my share of blown motors
03-19-2011
Not to thread jack, had me Rollin with the Mormon missionary comment.....
03-20-2011
In short, you're mis-firing under boost which means one of two things..... Too much boost is blowing out the spark, so you're either running the wrong plugs or to big a gap. Based on your mods you MAYBE have the ability to run a 3.4 pulley. And that's a stretch since you don't have a scanner.

^ This....if you're modded, you gotta have a way to monitor whats going on. Gauges arent for looks (unless you're a ricer) they have a purpose, and also the reason they cost a few bucks.

Here: 1.TAKE THE SUPERCHARGER PULLY OFF. 2. REPLACE WITH STOCK PULLY DONE.
03-20-2011
just cause you dont like the answer doesnt mean we didnt give you one. trust me you'll like it a ton more then a chipped piston
03-20-2011
Thank you ^^^^^
03-20-2011
Thank you for this. It's totally in my sig now.

x2. My AL104's gapped .055" suffered from spark blowout anywhere above 8 psi when I was running an intercooled 3.4" setup with headers.
What did you gap your plugs at?
03-20-2011
I don't have a problem with the answer when it's stated clearly and not with a bunch of (how could you ask that question like your all high and mighty and never made a mistake...) I was under the impression that this forum was for asking question to answer you didn't know and that people would give answer in a respectful manor...... heaven forbid i make a mistake and need some help... I would show you guy respect if you posted on a computer support forum...
