i have a 2000 TA with full bolt ons and a TR224 cam the car made 384rwhp and i still have stock injectors and fuel pump now i have the NOS5177 kit and want to run a 125 shot but would that put me to lean or should i just run a 75 shot.

 

with stock injectors and stock pump you will be pressing your luck on the spray, me and a buddy of mine had the TR224 cam like you and both of us were spraying dry kits with open noids with stock injectors and pumps. thats around 140 to the rear wheels, he ended up burning half of his piston down to the ring, i ended up having to tear mine down due to a spun rod bearing but my pistons looked fine, but he also sprayed more bottles thru his car than i did in mine. you possible could get away with it but to be on the safer side of the line you should upgrade your fuel pump if your spraying wet, and if spraying dry i would upgrade injectors also. get someone to log a run on motor to see what you injector duty cycle looks like N/A. and go from there. hope that helps some.

 

thanks man i will probly just spray the 75 for now and invest on so injectors

 

Run a 100 shot, and get a walbro fuel pump. Use the wet kit and you wont even have to mess with your injectors.

 

If you get a good A/F gauge you could keep upping the n2o until you see the fuel start to be lean....Its always better to play it safe, but unfortunalty you will never know where your at unless you get a gauge.

that sounds cool how much can i gat a guage for or do you have a kit to convert the 5177 kit to a wet kit...also i just want to say to dynotune that you guys have great prices i have 1 of your kits on my LT4 396 in my 95z and it pulls like a **** on the juice.

 

Thunder Racing sells a TNT conversion kit. 475.00 gets you a power ring, lines, jets(50-250), nozzles, and the soleniods. Get that and a Walbro 255 and you won't have to touch injectors, and be able to do a 150 shot fine.

 

I don't know, guys.... My mods are in sig and my injectors were operating at 101-105% on MOTOR alone on the dyno last thursday, before the spray, at only 6000 rpm. I'm getting them. Better safe than sorry.

 

I very much agree. Before I upgraded my injectors I logged some 106%+ runs WOT on motor alone. Scared me into upgrading...

 

holy cow thanks guy then i better get some injectors

 

if it is close you could get a hotwire kit,you really need one anyway but casper is running a special on the last time I looked.
