Puddle-ing?... how to prevent it???
lol...because things are not always simple. I think too many times in day to day communication we focus on one aspect of a complex problem. Thats where buzzwords are created. Just in the automotive racing industry alone they are rampant and usually misleading and can lead someone down the wrong path.
Why can't we just agree to use the buzzword "puddling" to discribe the situation of backfire causing an explosion of fuel in the intake manifold?
It would be simpler that way even if no actual puddles are involved.
The reality still exists that this can only happen with a wet system which fills the intake with fuel, and is prone to distribution problems because of incomplete fuel vaporization. I could care less if a puddle exists, the effect is still the same.
It's easier to just go with it since everyone uses the term already. It's like saying "the sun rises in the morning", not accurate but it conveys the idea.

It was just an idea to avoid more arguing.

Maybe some have heard that before...especially jets that are landing and powering up with the thrust reversers deployed.
The other scenario that seems to happen is too much juice at very low rpm.
Been looking at buying a car to show how and when a BOOOOMMM will happen.. YET no responces.
.... Just not that many choices around my area, and for some reason a guy puts a cam in a car at the price jumps 4k. lolAnyway the debate goes on. haha

Robert...I havent had an intake backfire ever. Wet kit or dry. I did go back to the dry for now. Not because I feel one is better than the other...its just very very simple to get 750 crank HP from 42 lb injectors, walbro 255 and the stock MAF. So its more of a convienance thing right now.
Now I did have a weird problem once where my crank was walking away from the crank position sensor cutting out the ignition. It would only happen on juice. I would get on it with a 250 shot and it would pull like a raped ape for 2 seconds...then die..but the fuel and nitrous was still pumping through the motor.....then...ignition would come back in
All the fuel in the exhaust pipes and muffler would ignite and just make a horrendous exploision out the tailpipe . My flowmaster mufflers were almost round and bulged out so much you could see where the internal pieces were welded trying to hang on.
I remember some poor Honda came buy me when I was troubleshooting this. he reved at me...so I armed the juice and hit it. The front tires were just scraping along with the nose pointed high as I flew by him...once I was about three cars in front the ignition died again...and immediately sounded like cannons going off and spit 5 foot flames out the dumps right in his direction....lol. I think it scared the crap out of him. He took the next right turn

Hey Ricky...good thing is you can use LS1 intakes. They are cheap and plentiful. I probably have access to a few. Just make sure you get some good video

Alright. ewll the car's tune should be stock as can be. The motor has a lil over 3000 miles on it and everything is stock (down to the manifolds and muffler)
Im am running a FJO Progressive controller with a HSW wet kit. My plan is to spray at 3000-3150 rpms from about a 35 shot and progress up to 100. IM not sure on what rpms im going to have it get to full power or when i should cut it off
I would assume, to be nice to my trans, it would be wise to NOT spray through the gears... (its a A4)
Thanks for that awesome responce 383...

Have you gotten a chance to play with the software?

No... but the idea is my trans has 80,000 of the hardest miles I have seen (bought car used). The motor has been replaced for a reason.
i want to make the trans last while i can

While were on the subject, I am running an LT1 with a Accel SuperRam intake. A BIG BOX w/ RUNNERS. i have heard many stories about this intake setup "puddling" because of how big the plenum is. Do u think i would be safe with a 100 shot dry? Thanks
Oh heres the link to a SuperRam on Someones car
