Dude, I didn't even want to mention that but remember it as I had the Twisted Wedges on my 5.0 back in 95 or 96. My buddy ended up having valvetrain problems with his but I must have got a good set. I would like to think they have everything down pat by now. The dyno numbers look good. Can't wait to see some time slips.

Above is an even better deal on AFR 205 heads for $1,850 plus shipping and I believe those may have made 447rwhp with an MTI stealth Cam (but you need to double check on that cam).

Buy something like these AFRs and be done with it bro and pm me on some chicago area tuners who would do a great job installing these for you!

 

the new ZO6 runs a 10.7 with just some drag radials.How far you'll get into the 10's is the question and how's your driving skills.

 

You can't go wrong with Cartek, the heads they use are 243 ported by them in-house. I went with the trickflows because I'm running a big cam and need the extra PTV clearance. If I run their ported 243s and milled them down to 61cc, I'd have to flycut. But that's not a problem with your cam. My friend installed a Cartek 2x H/C combo on his coupe and made 450rwhp with great street manners.

 

Yes, with a 427 LS7 motor and the best darn drag race driver on all the internet sites for vettes, RANGER, with drag radials, and it took him awhile and some good practice to get his Z into the high 10s from origially 11.3X territory. Only 2 guys that we are aware of have taken the new C6 Z into the 10s and that is with 81 more cubic inches and 100 more ponies and ft lbs and a sh it load more torque throughout the entire rpm band (which makes a huge difference when racing) over a C5 Z that this man has.

After owning 2 C5 Z06s (both modded) and 2 other C5s, one being a 427 C5R Automatic that was a 10 second car, trust me when i tell you that 10s in a n/a stock cubed LS6 C5 Z is not easy and you need the power but more importantly the driver skills and tires, to put the power down to the ground and to hit your shifts perfectly, etc., etc. How may n/a stock cubed C5 h/c Z06s with 3.42 rear ends are you aware that have gone into the 10s with a naturaly aspirated stock cubed LS6 motor. EXACTLY, only maybe and actually I have been on this forum for 6 years and believe all the Stock cubes N/A lS6 C5 Zs that have squeaked into the 10s have done it with 4.10 gears including C5 Z06 drag racing legend (ROBS Z)!

 

Here's the deal...All these CNC ported 243 casting heads can make good horsepower. What they lack though is the port velocity of a good aftermarket head such as Trick Flow 215's, AFR 205's, and ETP 215's. This velocity advantage the aftermarket heads have over ported 243's lead to better fuel economy, better throttle response, power under the curve, and just better drivability in general. I can understand being on a budget, but if you have the money, I recommend biting the bullet and getting one of the after market heads I mentioned.

Hammer

 

If he's buying Cartek heads then he def. has money for AFR/ETP/TFS, Cartek is anything BUT cheap.

 

I know you have your cam already and are going the sleeper route but below is a great deal on the LGM G5x3) cam in case you change your mind , and when matched with the AFR Heads I referenced above and a 90 LSX Fast intake you will make HUGE POWER!! This is a great cam for $275.00 (assuming it is in good shape with no issues, etc.).

Thanks for all the help to everyone trying to chime in and giving their opinions. I dont have a budget for heads, heads are something I need and obviously want to have good ones so I dont mind spending the extra buck or two. From what I heard from Cartek the 2x Heads Im trying to get are not all power but give good ETs and track times. Im looking for a sleeper 1/4mile set up car which will hit 10s on motor and low 10s on nitrous. Cartek said with the set up and the cam I got already ill be running 10.7s which is not bad and I understand I have to have all the other bolt ons to do it. If you guys check out carteks website they have the same spec cam i do running with those same heads (2x) and they hit 10.7s I know they are full built race cars and are light weight and track conditions are perfect with those times. What do you guys think for a sleeper setup could it get anybetter???

 

Are you ready to run 4.10s, ET streets, and leave the line at 4500rpm+? If so, you might be able to run 10s with the 2x package.

 

I do have to go with 4.10s???? I didnt know that. This sux. I do have the clutch the BFGs and all the rest of the stuff. I didnt know I need 4 10s. So there is no wa for me to hit 10s? on Motor?

 

I don't know if it's possible, but I think all the cars that I know from Cartek that hits 10s NA are running 4.10s.

 

That is also correct they all run 4.10s and are also running a sea level in New Jersey and most have et street slicks and launch off the REV LIMITER at 6500 to see the 10s on motor! The New Jersey tracks are one of the fastest in the Country (b/c of sea level) for sure and run considerabely faster than Byron, Il or Union Grove here in the Chicag area. Cartek is a great tuner and salesman, and trust me when i tell you that your car will not run 10.7s with that cam and just their heads (especially with your 3.42 gears) and you will not get into the 10s with the set-up described (on motor only).

I have been living and breathing this HIGH PERFORMANCE LS1 hobby very passionately for 6 years strong now and have owned and modded 4 C5s, including two Z06s and a high 10 sec Auto with 4000 stall and 427 N/A MTI built C5R motor with 3.73 gears) and there is no way you will see the 10s Naturally Aspirated with your set-up and with the cartek 2x heads and the cam you want to run. You will run around 11.2 to 11.3 assuming great driving, no traction and no breakage.

YOu will need a AFR/trickflow, type head and a cam like the G5X3 and 4.10 gears to get close to the 10s and that won't be an easy feat either. Also, plan on getting a FAST 90 LSX intake if you don't have one as you will need all the extra power you can to try to get into the 10s N/A on motor on a stick car in Illinois. WOuld be much easier if you had a 4000 stalled automatic with 3.90 or 4.10 gears. YOu might be able to get into the 10s with Cartek 2X heads with all of the other factors thrown in but I don't think that cam is up for the task and that needs to be changed for sure.

ALso, keep in mind the LGM G5X3 cam I keep on pushing on you not only performs GREAT on motor but AWESOME on the juice also (another factor you must consider when picking your final set-up). Call LGM motorsports and tell them your goals and they will reiterate what I am telling you here! Also, ask them how tuff it was for them to get a Z06 into 10s on motor on a fast TEXAS track with J-ROD (a real expert driver) rowing the gears!

YOu are setting yourself up for huge disappointment with those expecations but just run a set-up that you are comfortable and know that with the GIGGLY GAS you will be into the 10s no problem and the question is how far into the 10s (with the N20).

Don't get me wrong, Cartek is a great tuner and puts out a great product but if you REALLY WANT to run 10s (on a stock cubed h/c LS6 powered C5 Z06) and want to run their package, then ship your car to CARTEK and let them work their magic on getting you a 10 sec n/a Z06 and that will entail you going with 4.10 gears. THey are not that far from Chicago really when you get down to it and for their complete package with all their little performance tricks and tuning and gearing they will get you the car you want but it will be for a lot more $ than you realize! Cartek has put several Z06s on motor on New Jersey tracks into the 10s with their specific pacakge all working together and in unison with one another including the 4.10 gears and launching off the rev limiter or darn close to it and most with et streets and skinnies as tires!

Sorry for the long rant but hate to see fellow enthusiasts setting themselves up for a HUGE DISSAPOINTMENT!



Best of luck and don't get hung up on numbers and just enjoy what you have. Your biggest mod will be seat time, seat time, seat time, in your Z06, as experience at the track will be the best thing you can do to achieve your goals (on a manuel tranny) making big power!!!

 

I dont know If I am understanding you correctly by what was said in your reply you are saying a:

-Ported FAST 90
-Underdrive Pulley
-Ported LS2 TB
-2x heads
-LT Headers
-No Cats
-Honker Intake
-and a 007 Speed INC cam

And of course a very good Tune

I will not shave off a second on the 1/4 mile???

Right now Im bone stock with a catback borla not even an intake on the car and I ran a 11.9 with a terrible 60ft of 1.8.

I think that set up right there should give me close to 80 if not more RWHP and a little bit less TQ.

Am I really dreaming of hitting 10s on motor with all this stuff???

Should I be going with a procharger for the money Im spending on all this???

I appriciate everyones Help and pinions. I just had a mind set of getting to the results I wanted.

Now I have no clue what to do. HELP!!!! What is the cheapest and best way to achieve 10s on stock motor without using Nitrous??????

Thanks to all you guys for your feedback.

 

That is correct, you are dreaming with that set-up and you will not shave off a full second with your current plan and run 10s on motor. No way, it is very tuff to get into the 10s N/A on motor on a stock cubed Z06 and your set-up and driving skills have to be perfect and YOU NEED 4.10 gears!!!!!!!! You have to understand that is very easy to go from the 12s to the 11s but MUCH HARDER going from high 11s to high 10s and ever harder to go from high 10s to high 9s, etc., etc.
Also, Keep in mind YOU CAN'T RUN 10s on a heads/cam set-up on your stock LS6 motor without the car having a lump, lumpity cam and you shaking a few windows when you start the car up. The blower allows you to be like stock until you hot rod the car and I know you want to stay stealth.

Best way to do it: That one is easy, ECS compete PAXTON NOVI 2000 kit (and no i have no affiliation with ECS) other than running their kit and being very happy after 7000 miles on it and 0 issues and having more power than I can ever come close to putting down to the ground. A centrifugal supercharger kit offered by ECS or A&A making between 575 to 600 rwhp, with headers and tune, with proper traction, driving and no breaking, is the fastest, least expensive, and quickest path to running 10s on a stock motored Z06. See my sig for specifics. Many have run into the 10s at over 130+ mph with my exact set-up and power levels. It has been done and duplicated multiple times and your car will behave like it still stock UNTIL you thrash the pedal and make boost then it takes off like a F16 jet (and you can keep your 3.42s and WON'T NEED or WANT 4.10 gears).

Also, the new NOVI KIT ( i heard one today on my friend Z06 whose forge LS6 blower motor I just sold him) makes no noise and my friend is making 670rwhp on his forged LS6 motor and his car sounds bone stock and you are gong for stealth here so its perfect. Keep in mind YOU CAN'T RUN 10s on a heads/cam set-up on your stock LS6 motor without the car having a lump, lumpity cam and you shaking a few windows when you start the car up. The blower allows you to be like stock until you hot rod the car. The reason why a stock LS6 motor like we both have responds so well to cent. supercharging is b/c the 02+ Z06 cam MAKES AN AWESOME Blower cam and the LS6 heads flow well from the factory and the 10.5 compression, allows you along with the above reasons to make 600rwhp on 10 or 11 lbs of boost like FLP got me with my complete ECS Procharger kit!

You also have the perfect tuner here in Chicago area, FLP, who specializes in installing and tuning ECS complete kit and DAN BILLS at FLP is certainly probably the best tuner in the MIDWEST when it comes to f/induction on LS1/2/6/ engines. YOu will also need a new clutch (the textralia 0z700 is the best on market now that feels like stock) and at least a DTE strut brace if your drag racing.

Call up FLP and ECS and tell them you want to go 10s on your stock LS6 motor in your Z and they will reiterate what I am telling you. How do I know, b/c I have been there and done and if you go that route, run alky like i am running as its great insurance to keep your motor alive by keeping octane up, cooling down the cylinder charge and help preventing detonation which will frag your motor. Look at my sig for the power I am making on a 100% bone stock motor with headers and FLPs tuning!

Another good way to do it is with the TTIX twin turbo kit being offered but that wil cost you a few grand more and ECS complete cent supercharger kit with the NOVI 2000 head unit is your cheapest best bet to reach your goals!

Feel free to PM me if you want with your phone number if you need more info as i can talk a lot faster than type if you car confused by what I am saying and i can hook you up with FLP, etc, etc and ECS and they will give the confidence that you need to go in the right direction to reach your goals!

 

Here are a few examples of how hard they're launching their cars.

10sec Cartek Z06, but I think he had a 427 already when he made this run:

http://video.ls1tech.com/category/Co...66c9e118ff.htm

This is J-Rod, again I don't know the mods of his car at the time but again see how hard he leaves the line:

http://video.ls1tech.com/category/Co...366b2d9a4e.htm

A Cartek 3x package which will put out more than 450rwhp, 4.10s, ET streets, and a near redline clutch drop will probably get you into the 10s in perfert track conditions.

 

ok ,first of all, his Z will have near the same power and torque as the new one and will be a tad lighter .second,the c5 Z's are now making 500rwhp and 450rwtq on N/A 346's.I know it'll depend on the driver more than anything but it isn't that far fetched.

 

dude,I'll be surprised if ya hit 10's on that setup with no other mods .Especially, 10.7!

 

dude,quit beating the guy down.I beg to differ on the 10's issue and will soon prove it with my H/C, N/A stock bottom-end 346.You're right on a lot of stuff but it's not that hard anymore to hit the 10's on motor.I ran 11.7 @118 with a 1.7 60ft on ET Streets with just a CAI and full exhaust through a 3.42 rear.Some guys have way better times than that with the same mods but can drive better than me also.Nothing wrong with having high aspirations.

 

Robz one of the many who has gone 10s, h/c setup has less than 500, 480rwhp? Redgar a fellow vette doctor car has gone 10s with 450-460rwhp I beleive through his auto. Still going 10s in ANY setup period is hard, blown or not. Even blown with 600rwhp you will have to launch hard and be on a good tire (slicks).
With h/c cars making 500 now it will only help more. Not many track guys on here really, if there were, you would see more 10s like you do on ls1tech.

Also remember this is stock bottom end, most guys who go with the blower or turbo setup end up dropping compression and going forged bottom. Not saying it cant be done on stock motor, heck a stock ls6 with 7lbs making 550rwhp at the minimum SHOULD go 10s but I bet its not easy. Going 10s is not easy period.

I beleive h/c is the easiest way to hit 10s for the dollar. My .02
