425 rwhp is my magic number that I HAVE TO HAVE as that gives me 500 at the CRANK and I NEED 500 at the CRANK to keep me away from that new Z for several years. I have all the aggressive bolt ons listed in my sigs and for now must likely will stay with stock LS6 heads.

I know several here have hit that magic number i am looking for and I the the LGM G5X3 is a STOUT cam. Keep in mind this is going to be a daily driver where i put on between 12 to 15K miles a year on my Z and i need a RELIABLE SET UP!! I like the LOPEY HOT ROD SOUND and know others have had success with grinds in the area of 232/234, .590 to .600 lift on a 112 or 113 lsa.

I don't want to flycut the pistons and was wondering what the new bad boy streetable cam for stock headed LS6 motors are these days and if you hit the numbers I am looking for on a bolt on Z please let me know the cam specs by way of this post or IM!!

THANKS GUYS &LET THE SICKNESS BEGIN!!!!!!!!!!!!!!!!!!!

Take a look at my set up 430RWHP, I do not drive daily, but could

YES, I would be VERY HAPPY with the 430 you pulled as that=the peak HP of the new Z06 (505 HP at the crank) and I will take a real close look at the cam specs you showed me as they are nice and streetable and not overly BIG at all!

SmacZ

Well I was going to say MIKE did it!!!! But he already posted :P
I have seen his car yet since the cam but I know that should put you past your numbers goal. Those numbers though are probably the MINIMUM you will need to have a shot at the new Z. Drivetrain loss tends to be about 15% in our cars which means you would need 429RWHP. I also would have to guess the power band is stronger under the curve on a 427 than a cammed LS6......... Just get the bottle......it will keep you fine for daily driving :P

Use the T-Rex, you SHOULD fly cut, but you dont HAVE TO (i would). Some guy got 450RWHP out of his non stock 243 heads.

def. obtainable . I put down 422 rwhp and 376 torque. I dynoed on a 95 degree day. alittle cooler and alot mroe hp would of been shwon. I have stage 3 cam from tt performance which was done amazing. Great work by them. Its called stage 3 equalizer package. I ahve 1 7/8 kook headers with off road x-pipe. Corsa exhaust, granitelli intake with coupler. Short shifter. Thats all i have for performance mods. If i ut 90mm throttle body, lsx intake manifold, i will have 450 almost or more.

BriansZo6

daily drive. Put like 20k or more on a year. Put 25k on my first year and just installed the cam and put another 4k on it with the cam.

A cam big enough for 425+ rwhp on stock heads will not be a very happy daily driver... unless you like that sort of thing every day.

Morzoff

Cobra4B,
I just installed a cam and got 430RWHP (STOCK LS6 HEADS)
and the car drives the same just more power, I do have an Idle issue that needs to be corrected we have it tuned to hang up and then drop down, at first it bothered me, now it's ok


Mike

Morzoff

The power curve on a 427 should be stronger

That's why I have a bottle coming

Mopar Jimmy

Are you running the G5X3 cam and if yes on a 114 lsa. If not, what are your cam specs?

Airwolf

Just add a little "juice" and make your worries fly away!!! Getting ready to add the cam in my sig Aug. 6th and will let you know after Norris Motorsports tunes it. Hoping to be in the 420 range off the bottle and well over 550 with it.

Mopar Jimmy

Nothing pesonal about those who like the juice but that N20 stuff me NO LIKEY (although i agree it the cheapest way to go fast but the most dangerous to for your engine)!!!!!!!!!!

Airwolf

Everyone fears what they don't know. It's part of life.
A few years ago, NO ONE would have put a turbo or supercharger on an 10.5:1 compression engine, but just stop by the FI section and plenty do it now! Funny how things change when the mystery is taken out.

I respect your opinion for your car 100%, but wonder what you base the statement on...

PS - running low on oil or coolant is the most dangerous for your engine, but these are monitored... Oh, so is my nitrous system!

Mopar Jimmy

Not looking for any debates pro I just personally am not a N20 Guy probably primarily b/c i like to have the power there 100% of the time as part of the engine everytime i put the pedal to the metal.

ENJOY your Vette and be safe!!!!!!!!

zo6vetteman2003

If you look at my sig. I am doing it on stock heads. Note the torque with Kooks LT's. Mods. coming are AFR heads and FAST LSX intake.
This is SAE corrected too.

Airwolf

Will do. I will post the numbers on my cam after the tune for you next week.

zo6vetteman2003, your cam was my other choice, but going with the next size up. How is the idle sound? I bet it is cool with the 112 LSA. Nice numbers with it. I have seen similar numbers posted here with that cam on another Z (the person had SuperMaxx though), so it seems like a VERY good choice without beating the valve train with a huge lift.

robz

Goodluck with your goal. I gave you info on my set up in another thread. I would shop around and get info from the tuners as well. Dave at Cartek is a good source of info.

Ebbsnflows

I don't mean to Hijack this thread or send it off on a tangent...but how is 425 at the wheel equal to 500 at the crank? By my math you'd need 440 rwhp for 500 at the crank? I thought the accepted parasitc loss was 15% in on a Z06?

15% of 405 (stock) hp = 345 rwhp (about the AVG dyno of a stock Z06...give or take), or a 60 hp parasitic loss. Based on that assumption 425 + 60 = 485??

What am I missing? You're not calculating based on 15% of 500 hp are you?

J-Rod

you'll need 450-460 to equal 500 crank HP.

With that in mind, you could get 400-410 with a very sneaky stealthly cam. More than that is going to have some chop.
