Magic Stick V.4 239/242, .649"/.609" Camshaft
1-3/4 long tube headers
heads have been port and polished
cromemoly push rods

in short "yes"

how big of a shot are you going for?
if you're staying 100 or less, you should be fine with what it's got,

if you're planning on going 150 shot, you will "need" a 255lph fuel pump to prevent a lean spike when you hit it (and possibly to keep up at the top end of the rev's)

also,
make the Fuel line as short as possible,
make the nitrous line 12-24" longer, that will help keep the nitrous from hitting the plate before the fuel (causing a lean spike)



I'm running stock fuel pump (not for long)
and a 100 shot wet plate kit, (100hp Nitrous pill, 125 or 150hp fuel jet) and running a 12.5:1 lean spike, levels off after 200rpm or so at 11:1 afr any other combo kept me too lean for too long



good luck




bTW,
you will get better N2o info in the nitrous section

Never thought about that. I was just planning on adding a bit more fuel in my nitrous tune or doing the larger jet like you said.

But yes you will need more fuel mods. I added injectors, and a pump this year knowing I was going to need it. Surprised you havnt needed them already yet. OR you could run a stand alone nitrous fuel cell but it will cost about the same, probably more than the injectors and pump.

What everyone has said so far is good advice. I run the Racetronix kit with 42lb injectors, with a Nitro Dave's 90mm plate kit on a progressive controller, and I have no no problems with my set up what so ever. I would highly recommend The Nitrous Outlet.

I hear with the TNT kit there shots are rated more than what they say they are, like for and from a marketing stand point. Say your pilled for a 100, its essentially a 125 at the wheels. Thats what I've heard, I dont know if anyone else has heard such a thing.

ohh and Good Luck with your decision on a kit

I would say it doesn't matter how large of shot you are adding you are already at 450rwhp. So unless you are planning to spray a 25 shot you will need something.

If you don't want to mess with the pump in the tank take a look at this.

no need for injectors with a wet kit

on stock motor i agree. but when you have a cam and heads in his case i would. just a cam on my part and i was at 95% duty cycle on my stock ones. so i upgraded.

I was in the same boat, since I have a heads and cam, I picked up a significant amount of power also by upgrading injector size.

KrautBurner

you guys are both running the LS1,
the LS2 came with bigger injectors,



but if he's running 95% duty cycle,
I'd advise upgrading as well




I'm pretty sure mine do fine with my cam,
but my cam isn't as agressive as the above cam
I'm also about 50rwhp less too

NEW #'S it made 573. rwhp with 100 shot.
