I have a stock Z06 without any modifications, so not speaking from experience. But I do not see how bolt ons, with cams and some port work will add 350 hp. The biggest restriction is the factory supercharger and you haven't done anything there. I would think this combo would add about 100-150 hp.

chevyfanatic

Entrenched what are your current mods for the 715 whp ?

Are you running meth ? or just E85 with new pump ?

chevyfanatic

we are targeting like 750 whp. Spoke to soon as we might touch 900 chp on a good day.

Big question or issue is no Meth and stock injectors. I am not convinced you need new injectors for 750 whp but Meth maybe needed.

SalsZO6

That shop Sonic MS doesn't even specialize in GM cars why are you going there? They work on German cars mostly (bmw,AMG, etc). You need to go to Synergy Motorsports and talk to Rick in Livermore or Matt with GP Tuning. These guys build high power GM cars all day long and have built plenty of C7Z cars.

chevyfanatic

cause Aaron has done a bunch of builds before at Borelli before they got taken over. he was at Borelli before and did a procharger pushing out 800 whp.

l888apex

Injectors would be easier, ran a meth kit on another car (not a C7) and it is a huge PITA. Your tuner should prefer getting fuel in the proper way over a 9th nozzle with a pump, tank and all kinds of other variables to put in play. Plus, constantly refilling and buying methanol is annoying. On a car like this I'm not sure why you wouldn't prefer a slick solution. This isn't a JDM ricebox.

chevyfanatic

Exactly ! thats what he said too !

here is a build almost like mine but running a more aggressive Cam on stock Blower and 802 whp

Ultimately outright dyno numbers are silly, it's a tool used for tuning with outdoing dangerous street pulls to simulate lots of conditions and to give some idea about baseline vs. modified numbers. There are so many variables you can adjust to cheat the numbers up, I know as I have seen it done many times.

chevyfanatic

I have a lower pulley to but he said dont use the upper pulley ! if I get to 750 whp I will be super happy ! Plus tuning the TCM will help too and make the car more responsive.

Remember we are only at 530 whp stock so this car is going to be very fast compared to 99.99% of cars on the road. 9 secs for sure on DR

l888apex

Yes I misread the YouTube link, thought he had both lower / upper pulleys. But yours is listed only as a harmonic balancer so I did not think it would increase boost over factory.

ChrisG23

Meth is a valuable addition to the car if it is used as intended, as a liquid intercooler. If it is used to supplement the fuel injection system then yeah, that is ****.

chevyfanatic

No he originally said its 10% OD - from this email

going to switch to primarily 1/2 mile and mile events after the procharger 1000+ at the wheels

h3mpking

Crazy..I made 701 with just bolt ons. Nothing ported and no aftermarket cam. Have you ran any half mile or mile events in that configuration?

entrenched

No. Based on MPH in the 1/4 mile, power is right on. Making the switch to limit breakage until we have upgrades available for the diff and trans. I stopped paying attention to dyno sheets and try to spend time performance testing.

ferraf

JMHO: The build you are proposing unlikely reach into the 700's who. Set expectations correctly with 640-660whp and be surprised anything else above. Total flywheel HP I'd put a guess in at 775-800HP. the quote you posted is VERY similar to my build less the heat exchanger (SAME COST AS MY METH KIT) and 4k higher cost. something to consider is price out the job once you know what you need.

I'm not a builder only a customer with what I've seen, purchased, and discussed with the experts it's unlikely to reach 700 whp.

Suggestions people have made are spot on and excellent choices


Enjoy and have fun with whatever you choose!

No, you will run out of fuel

chevyfanatic

thats laughable dude.

other builds like this are over 700 whp. did you actually look at the MODS ?? headers/cam/E85/ported heads ! lol

chevyfanatic

not sure - obviously you guys over at MTI know far more then me but we are upgrading the CAM and fuel system.

My understanding is METH is good for ultimate power but not totally necessary.

ferraf

Okay dude, you asked. I know what I pull which with Meth which is more than E85 alone... If you trust the guy who spec'ed your car then just spend the money and don't ask. You do know 1000HP at the fly is just over 800HP at the wheels. The 700 I'm saying you'll maybe hit is close to what number is in your head.

That build will not come close to 1000 HP. You'll get maybe 20-30 hp more than I suggested to set goals for.

Go for it and get a good dyno readings and let us know what reality is. The guy with the Procharger F1 without a second thought has a killer setup that is a 1k+ HP build.

Also these C7 Z06's are heat monsters. Meth is supplement fuel, but more used to drop intake temps to advance timing and yield more power a the same temps before you overdrove the SC. When overdriving the SC keeping the temps down is a must. For me every LT4 engine could use the dropped temps (40-50 degrees). If you're going to drag at the track it really helps keep the temps down and yes provide a little more power by adding maybe 4 degrees of timing to your tune.

Best
