I'm currently running a TFS top end kit(Street Heat heads, intake, stage 1 cam) on my stock bottom end with 24lb injectors. What's everyone's opinion on how high I can safely take the jetting before I run out of injector?

Is the kit you are planning to use a dry or a wet kit? Wet kits supply fuel and NO2 to a combination injector. You change the jets in the NO2 combination injector to match the HP increase you want. With this type of kit, the main concern for the fuel system is to make sure you have a big enough fuel pump to provide fuel for your 24 lb injectors and the NOS combination injector.

You neglected to mention if you had an aftermarket MAF or custom tune to match the 24 lb injectors to the computer.

The NOS 05115 kit is a dry system. I have since decided to not take the chance and just go with a wet system. I'm about 75% percent done with the install at this point. FWIW, I have a 255lph Walbro in the tank and the MAF is tuned for the 24's.

if you run a wet kit that sprays at the TB, limit the amount the amount of nitrous (thus fuel) that you use. if you pill it up too much you might have issues with fuel puddling in the plenum of the upper intake. then it leans out and a nasty flame spitting backfire is the result.

Got it all done yesterday and took it to the track last night. Ran flawless all night long.

12.80's @ 111 MPH with a 100 shot. The local track is at 2800 feet of elevation and the temps were in the low 90's.
