Black- 2002 Camaro
Looking for some talk on my new set-up!!
Hey everyone!!!
I just finished my engine work on my Z28 today, and I was looking for some input and some help....
Here is everything I have installed in the past few days...
Fibreglass SS hood (functional)
SLP Lid
Granateli MAF for cold air
SLP Smooth Bellows
Billet steel double roller timing chain
Comp Cams Cam 222 224 @ 050 with 566 568 lift on 112 LSA
Comp Cams Pro-Magnum roller rockers
Comp Cams 1-Piece Pushrods
Comp Cams Beehive Valve Springs
Dynatech Stainless Long tube headers, Y-Pipe, Cats.
Flowmaster after cat system
MSD Coils
MSD Super Conductor Wires
NGK Plugs
Meziere Electric Water Pump
Underdive Pulley
I couldnt wait to start it up so I havent put on any of the exaust after the headers but when I started it up it seems to really idle rough and the engine seems to be doing a bit of shaking, I use EFI Live and while scanning it I noticed that the timing is severly eratic, and the engine really seems to have trouble holding RPM. I installed brand new O2 Sensors as well and I also noticed that it really seems to be running rich, (making the eyes water in fact) this blows my mind because I should be running a bit lean if anything.
Any thoughts????? I know that when your running just headers you seem to have a chopier idle but I cant se it causing this much of a chop. Plus I think the timing has something in common with it..... By the way... I am not seeing any knock retard.
I am going to install my 60-lb injectors soon as well as my exaust, Does anyone have any idea of my horsepower numbers????? How about a 1/4 mile time???
I am running a auto with an aluminum driveshaftm and 3.73's on a Eaton Posi, plus I am using all BMR chassis components so I believe I am like 60-70 lbs lighter than stock, but I will be installing a Chromoly Wolf 6-Point cage. I also have 2-stages of NOS... a 150 wet-shot progressively controlled, and a 100-dry shot button activated.
Any help is great guys!!!
One more thing... When I started it up I didnt see any oil pressure for like 10 seconds.... This to me was a little alarming... After that the oil pressure seems a bit lower than normal and it seems a little eratic.

you need to get the a/f ratio.
ideally it should be a flat 13.
the flowmaster is going to choke some h.p. its one of the worst flowing catbacks out there.
being that youre an automatic, you should have a stall converter, no less than 3000 rpm.
n/a you will have about 370- 380 rwhp2000 nhra edition formula
a few bolt ons, 379 rwhp

My car is dropped with the Eibach ProKit and I easily run custom 3" duals.

These injectors were not ment for this set-up but I am using them anyway... I also am building a 427 LS1 that will make about 800+ HP plus Nitrous

Yeah, I realized this before I ordered it... I went with it though because I dont plan on using the N2O all that often, and so I was mainly looking for a cam for natural asperation. The main batch of my mods is intended for the 427 I am building, I am still about a year and $7000 away from being finished so I wanted a little more power for now and got a cam, then I figured while I was at it I might as well beef up the rest of the valvetrain.

I plan on using this cam in my 427 when its done, so it should act milder with the added cubes, I will also be using a 2800 Stall converter when its done... That at first sounds low but you need to remember that its seriously stroked so I should have gobs of torque down low, therfore I wouldnt need an excessively high stall converter.
Thanks for all your input.
