Default powerdyne newbie needs help

Hey, I am about to put a pwerdyne 6# kit onto my almost stock (see sig.) Z28... I've heard talk of telling me to up my fuel inhectors, is this true?... and what size do I need?

on a side note: anyone know where you can install a gauge other than the same ol' A-pillar? I want to put it in the little pocket next to the cig. ltr, anyone know where a kit for doing this is?
thanks <img src="graemlins/gr_cheers.gif" border="0" alt="[cheers]" />

I myself would recommend the bigger injectors. you will easily max out your stockers and then rely soley on increased fp from the fmu to force in enough fuel. not good IMO.

if you like you can email me and I can give you all the details of my own pd setup and the one I helped setup. The other is currently putting down 401/406 on 91 octane with the blower and a borla as the only power mods. Mine has and will have significantly more mods. No numbers yet since it was the stock car with 4.5psi. Those numbers in sig.

you can find his numbers on ls1.com under the fi section. we can still squeeze more tq out of it up top as its going quite rich but the dyno broke before we could finish tuning <img src="gr_sad.gif" border="0">

as for the guage in the cubby hole you mean like this?

feel free to email me. I will be glad to help get ya going. <img src="graemlins/gr_chug.gif" border="0" alt="[chug]" />

custom work if you can call it that <img src="gr_stretch.gif" border="0">

80 cents worth of plastic from a local shop called tap plastics and a minute or so with the dremel and sandpaper to round the edges for a little nicer fit.

I just checked out all your pics on your home page blackbird, sweet setup, although Im a little confused on the custom tubing?... anyways, on the setup thats running 401 hp with 91 octane gas, is exactly where I want to be, will I have to advance the timing?...
any other mods you suggest by putting on my Pwrdyne?

thanks. one of these days I really need to update that page with better pics and explanations.

the tubing you see is because I mounted a conical air filter in the fenderwell instead of attempting to use the stock air box. this is a very beneficial mod. You will see a little more boost and pick up good power over using the stock airbox.

as far as timing goes you actually need to pull quite a bit if your running 91 octane.

I don't know who/what your going to use for programming but when the time comes I could provide you with the tune I am using on the car that is the blower/borla only making 401/406 at this point. That can give you/your tuner a place to start at least.

the only other thing you will want to do they don't mention in the instructions is to put a checkvalve in line with the pcv system to prevent misting oil into the intake. this is a must do or the car will ping all the time. I know from experience <img src="gr_stretch.gif" border="0">

use a stock maf
ngk tr6 plugs
I recommend 36# injectors
if you change injectors you also need the fmu recalibration kit if your keeping the fmu, otherwise the car will get SUPER rich when you get into boost.

and come up with something clever for the fans or you will have problems come summer. both my friend and I have 2 differnt things we are going to try out regarding this and I can let you know what works and what doesn't

thats all I can think of for now.

when do you start the install?

where do I get the FMU recalibration kit? also you mentioned stock MAF, i put a granatelli MAF on it, will that matter? I start my install when I feel I have enough info/courage <img src="images/icons/confused.gif" border="0"> the kit came with electrical fans, is this not enough i assume?

again, thanx for your help, I dont know anyone in the area specializing in LS1's (Utah=crappy)

powerdyne sells the recal kit.

you could get it tuned for the granatelli I suppose but I think you will find it easier to tune if you use the stock maf. it's just a variable I myself would rather tune without. It's not going to beneficial over the stock maf imo.

they give you 3 fans right. 2 for the ac condensor and one for the radiator. it's not enough as the system is not sealed up well enough.

as I mentioned my friend and I are going to tackle this issue 2 different ways. I will let you know how it turns out. you can install them their way and be fine until you hit stop and go traffic in 95+ degree weather. so don't panic it's not too bad.

the install is pretty easy. just gather all your parts and go for it. then DON'T romp on it until you get it dyno tuned and all will be well.

one other thing, appears sigs dont work. whats your other mods you speak of?

well, it's mainly just stock, just airflow lid, MAF, and B&M ripper shifter. that is all. there arnt many dynos in Salt lake city, does a mechanic need a dyno to tune it right?...

yes, you need to be on a dyno with a wideband so you know what your air/fuel ratio looks like.

otherwise you could go lean and blow a head gasket or worse, or be so rich it doesn't make much power.

who are you going to have do your programming?

See, Thats what I am afraid of, is that most speed shops here in Utah specialize in imports <img src="gr_sad.gif" border="0"> But I will have to ask around, see if I can find someone that knows what there doing, I've heard of some people doing it themselves with a laptop, Is this kind of out of the question for a semi newbie like myself?...

not really.

if you get ls1-edit I can get you there via email/telephone.

your lucky as I am pretty much tweaking the program for the pd/borla car almost everyday.

if you mimick the setup you could practically cut and paste the tune.

what year car is it?
