98 H/C Z28 thinking of spraying in the future.
My car currently has 36# injectors and the stock pump. Parts list is as follows:
TSP Magic Stick 4 Cam 239/242 .649"/609" 111 LSA
GM LS6 Race Heads- 61.9cc, 250cc Intake, 85cc exhaust
Yella Terra Rockers 1.7:1 Ratio
PRC Dual Valve Springs w/Titanium Retainers. Previous owner says the springs only have 300 miles on them.
Thunder Racing Hardened Pushrods 7.4"
GM CTS-V Race lifters (GM 88958689)
ARP Rod and Main bolts
Powerband Underdrive Pulley
BBK 80mm Throttle Body
36# injectors
Ported MAF
Jet Hot 1 7/8" Longtube Headers
4.10s
Do I need a Racetronix fuel pump if I plan on spraying a 100 wet shot in the future?
I see plenty of threads on the limits of the stock injectors and how you don't want to go over 80% duty cycle but I have the same question for the 36s I have. At what point do I need to think about 42s? Car dynoed at 441 rwhp.

Not sure how much install is since I did it myself. It's very easy doing the trap door method just so you know. The hotwire kit basically boosts the pumps capacity a little more so it can flow more fuel. At your power level I'd do it. I'm running that setup and make similar power as you
