I am putting in a whole new madman rear suspension, wolfeanti roll shocks, springs, and a 9". Car also has the short Chassis Engineering TQ arm about 1' behind the cross-member.
Runs 11.90's right now on motor @ 113.
I just got a complete NX kit setup with a single shark nozzle just before the TB.
I have an innovate LC1 A/F setup logging into my laptop.
MSD timing twister to pull out a set amount of timing then the nitrous relay are activated.
nitrous system:
NX 15lb bottle
NW warmer
HSW nitrous switch panel and TB mount solenoid bracket
-6 from bottle to under hood
-6 inline nitrous filter -4 out
-4 into Big NX lightning solenoid and -4 out to nozzle
-3 fuel side from factory rail (FP Gauge and FPSS)
- FJO Progressive nitrous controller
The cam is a texas speed .581 .224 .224
What is the max amount you would spray on the car with timing pulled? Is 175 too much?
Its not my main transportation, so I don't mind pushing it a little.
But I'm worried about what my stock fuel system will support, until I get it upgraded.
Should I start with a 75 or 100 and work into a 150 max hit?
With the FJo controller, I can spray it out of the hole at a lower amount, and fade into the full hit. But I also want to be able to race it all weekend without blowing it up.
I was going to make some NA passes first ang log the A/F, then pull timing and spray it and look at the data and spark plugs. THen slowly move into a larger jet.
Thanks

Right now its putting down about 360-370RWHP through a A4 4l60e, 10 bolts, and 3000 TCI stall. So maybe 425 at the motor??

Well.. looks like I need to add fuel pump to my list before going to race next week.
Now I need to decide what to get.. inline or in-tank I guess...
At least the 9" and 3.90 gears are in the car now.. just finished all that up tonight.

GTP factory 36 Lbs. flow fuel injectors. These will fit GM 3.8 / 3800 series III L32 supercharged engines.
The part number is 12574393. These are the blue / gray in color.
About $100 for 8 used injectors.
I would need a new tune if injectors are changed right?

To the OP.
Lets slow this down a bit. Your going way too fast here.
With all due respect to some of the above well intentioned members STOP, and do some research before you spray.
Just a few of the things that worry me...
1. You say you have a shark nozzle mounted right in front of the TB, which is ok if you are running a wet kit. But you follow that up by asking about injectors.
You won't need injectors with a wet kit.
2. You need to upgrade your fuel pump. You may or may not be ok with the 75 shot, but going anything over that is asking alot.
3. I may have missed it, but are you still running the stock plugs?

#2 - I'm in the process of upgrading the pump right now. I have a FPSS switch on the fuel rail and set to cut the solenoids off if it drops below 40. Gonna pump this up a little after I make a few passes on the kit.
#3 - Running TR7 plugs and pulling out 6 degrees timing with a MSD timing twister.
Also have a bottle heater and purge.
I didn't rush into this, just wondered how may people spray 150 or so before upgrading the fuel pump.
So to be safe, I'm going to upgrade mine as well.
I will upload some pictures tomorrow when the wiring is finished.

A few more wires and I will upload some pics tomorrow night.
I ended up putting all the relays, nitrous controller, innovate A/F box, etc under the back seat and hid all the wires. Just have to run everything from the ash tray switch panel to my power blocks and I'm almost done.
