ok from the searches i've done i see that the TSP 233/239 cam is about what i am looking for. as it sits right now my engine mods are:
TSP 224r cam 114lsa
comp magnum pushrods
patriot gold dual valve springs
pacestter ceramic coated longtubes
melling high volume oil pump
n-motion LS2 single roller timing set

before the cam swap i will be doing a FM merge with a mufflex cat back. also will be grabbing an ls6 intake and ether a ported tb or an 80mm tb of some sort. but other than that would you guys recommend to go with this cam? will my fuel system be able to feed it?

bigger injectors.pump?

brian_rs/ss

yeah but what size, do i really need them? this is my DD btw.

I believe you have #26 injectors.from what I under stand they can support 360rwhp safely .your new cam and upgrades will make 400 rwhp.I feel #36 injectors will work.

Stock injectors will work past 360rwhp... Just because an injector is over 100% of its duty cycle doesn't mean its maxed out. I have stock injectors on my setup. Talk to your tuner about it, see what he can/can't do, what he thinks is a good idea or isn't. I have a lot of trust in my tuner, so whatever he says is generally what I go with.

Actually, yes it does. If the injector is at 100% DC, its out of control. Its just forever on, and never closing. Once you need more fuel than it can give at 100% youll go lean.

I'm not going to say you're right or wrong, I'm not a tuner and I have no idea what you've done or not done. I'm just going by what I've been told. Maybe an experienced tuner can shed more light on this?

so possibly 36 lb/hr? what about fuel pump?

i am already past 360 rwhp...by about 15 hp...and at WOT my car screams. but who knows my butt dyno might be a little off.

g-force tunes my car and i have a lot of faith in them so i will see what they recommend, i was more asking on here to get an idea of how much i might need to spend.

Okay, after doing some quick surfing on the board... You can run your stockers over their max DC, but it's not recommended... Most everyone is saying once they're maxed, go bigger. If you want some references from here on the board, just search "injector duty cycle" it'll come up with some good material.

what heads are you using?FM merge $55,cat back?ls6 intake $300 used ,$480 new SDPC.85 mm TB $300.I think you pump will keep up with ,that cam will wake it up some.can of worms,stronger rear end,drive shaft.it is fun and worth it!

brian_rs/ss

stock heads, and yeah i know what all this **** costs dont remind me!

thanks IWGF, i'll search around and read up on it before monday when i can call my tuner.

No problemo mang. I was under the impression that you could safely run injectors past their max DC. I'll have to ask my tuner about it, I probably misunderstood something in that...

brian_rs/ss

hmmm ok i searched around and its a pretty confusing beast so i'm going to leave the size of injectors up to my tuner. BUT i need a good place to buy injectors from. most websites only seem to carry one brand. like thunder racing only has racetronix and tsp only has FAST.
