Dry kit on LT1 Anyone spraying in front of
Dry kit on LT1 Anyone spraying in front of Dry kit on LT1 Anyone spraying in front of the MAF? I was wondering if I could spray a dry 100hp in front of the MAF? If I add the dry kit I dont want to go the route of spiking the fuel pressure. I will be going with 42lbs or higher injectors. I currently have a dynotune 150 wet and was considering going DP. But if I can make this work and spray 250-300 total in two stages, while spending less money I'm sold.
I'm pretty sure the LT1 computer is the reason you can't
spray into the maf and use the computer to compensate
with extra fuel.
The LT1 computer just doesn't process info fast enough
to prevent a massive lean spike.
Thats why the NOS 5176 kit boosts the fuel pressure
while spraying.

So looking to get a 100 dry before the MAF is a bad idea?(You said normally?)

I don't want to sound like I'm questioning you. But I was hoping that they increased fuel pressure because of the small fuel injectors that actually came out in 93-94. 19lb injectors cant really support the extra horse. If I cant safely spray more then 50-75 Maybe I can come up with the peices to spike the fuel pressure.
Thank you

I have a wet kit now and would like to increase what I spray. I'm considering adding a dry nozzle in front of the MAF. This would be to make a dry/wet 2 stage system. I wanted to know if anyone has put there on system together for the Lt1 like what is beening used on the LS1 spraying a dry nozzle in front of the MAF so that you would not have to raise the fuel pressure.
Well I read the instructions for the 05176NOS kit. I would still like to spray 100 dry in front of the MAF. But if I cant I would like to buy the stuff to piece together a dry first stage. The NOS kit uses a 67 jet for 125-150hp and 160-200lbs torque. I don't see any way of adjusting their air fuel ratio. I would like to run around .048-.050 jet for the dry stage. If I use a nitrous pressure reg(15850) from a dry kit(that I already have) how can I adjust the fuel pressure? The vacum hose tee(17538-s) has a built in orfice. Are there other tee's with replaceable jets? If so what is the part number?

Like Robert said I wouldn't try it in front of the MAF it never seemed to work well on the older cars. The current vaccum tee that NOS offers is non adjustable. However there are places that still make the adjustable one. If you go to drynitrous.com I think he has a link to where to buy the adjustable ones. Below is a chart that has the the pressures for the diffrent bypass jets. Stock for the LT1's was 67nitrous and 59 in the tee.
blue finish@ 50psi
jet size std psi psi w/ shim
.000" 50 65
.020" 46 60
.030" 45 60
.040" 43 59
.042" 43 56
.051" 40 54
.059" 37 50
.070" 32 46
.080" 29 42
.125" 26 34
Although if you try running this with a wet kit you may run into problems with the wet kit running too rich due to the higher fuel pressure from the dry kit.

My car is a 96' car and i sprayed 100dry for years but every car is different.
I had 150 on the first stage wet and 100 second stage dry with 42lbs inj. the car ran for years and made some nasty numbers. But it was a forged motor.

How was your dry hooked up? Spiking fuel pressure? Spreayed in front of MAF?

Thanks for for other site and jet/pressure chart
