What precautions should i make with a dry kit in order not to have the fuel puddling (sp?) in my intake?
I'm really-really afraid of having a backfire because of that, and might even go "dry"...
I still can't decide whether dry or wet...

 

with a dry kit,you cant have a so called "puddle"in the intake. DRY Kits use the INJECTORS for fuel enrichment.Wet kit's mix fuel AND nitrous AT the nozzle,where as DRY only shoots nitrous from the nozzle.

FWIW,i have been using wet kits exclusively for over 9 years,NEVER had an issue with fuel "puddling". Have had a few backfires from being lean or a solenoid sticking on an OLD setup,and the worst backfire blew the air filter apart.

 

I was twice as scared as you, since LS1's are better known for puddling, and a backfire can break our composite intake manifolds ($400).

I'm spraying 100 wet and no problems. I took my time and made sure i had good nozzle placement, and use a window switch and fpss and you should be fine.

 

Hmm....i dunno. Thanks for the replies!

 

What is unclear to you?

A dry kit will not puddle the intake.

 

Yes, I know that! That's why i'm leaning towards the dry setup, but some people tell that the wet kits are as safe as the drys.
I dunno yet whether to go with dry or wet. BUT that's MY problem

 

Just about all the LS1's are running dry, but they have larger stock injectors.

For a safe setup, i'd run a wet kit with a fuel pressure saftey switch and window switch. Lt1's are only known to backfire if you spray at too low of an rpm or into the revlimit (window switch prevents that) and the fpss and wet shot will prevent it from going lean.

 

rpm4lalo, i believe he made a typo on his first post and meant to say wet kit for puddling.

 

Ohhh,shh....Yes, i didn't even noticed it!
Of course i meant WET. Bah.

 

I like "wet" as it's much easier to tune fuel. And yes, a dry kit won't puddle fuel.

A Dry Kit May not puddle like a wet kit, but they can still backfire!
I've seen it first hand. Two cars on the dyno the same day. Both sprayed at 3k. Backfires occurred at about 4500-5000rpm. Both were pretty violent.
