Default lt1 nitrous questions

ive never messed with nitrous before but im looking at getting a dry kit, and progressing to a 150 shot.

my question is, should I get a plate kit or a kit that injects the nitrous infront of the MAF?

it seems like that 2nd choice would be easier to setup and tune

LT1s do not use "through the MAF" dry systems...the PCM wil not add the extra fuel reliably

LT1 dry kits use the nitrous flow to force the fuel pressure regulator to increase fuel pressure which in turn forces more fuel through the injector when it opens for its normal duty cycle.

I would suggest not running a dry kit on the LTx platform...go wet and call it a day

I agree. I never had very good results with a dry kit. I then converted to a TNT wet plate setup, and whoa buddy. I'm now running a Nitrous Outlet plate.

how come dry kits dont work very well? does the maf max out when it sprays or does the computer just not adjust fast enough?

Correct...its not reliable to use the MAF/PCM calcultions to provide proper fueling. This is why every company that offers a dry kit for the LTx plarform does not use the MAF/PCM to provide fueling.

Why are you wanting to use a dry kit on that particular application?
