Just thought I would share my build for my 2008 VY Z06 weekend / soon to be track car.. let me know what you guys think and if I should add anything.. pistons are almost ready. Then engine will be built and dynoed at CPR Engines in Gardena CA..

Stage 4 Race ported / flycut heads / BTR 3 Cam
Ross Racing custom 13:1 pistons
Upgraded cylinders by LA Sleeve Halltech CarbonFiber 112mm Air Intake Nick Williams 102mm Throttle Body
Tony Mamo Ported / Shaved MSD Intake Manifold
2" AmericanRacing Headers
3” Catless X-Pipe
Corsa Exhaust
DMS flex fuel kit for e85
Fic1000 injectors
2012 later Z06 fuel pump
MightyMouse Elite catch can
Trunnion rocker shaft upgrade
Mantic 9000 Twin Disc Clutch / Flywheel
Pfadt Engine / Trans Mounts
ATi 10% Under-Drive Dampener Pulley w/o Air Conditioning
Katech Ported Oil Pump 30% Scavenge

That just about does it.. 160* thermostat ?

Thanks!

Looks real good. Those are all top notch parts and I am sure she is going to scream.

But if this is a track car, what have you done to address the following?

• Brakes
• Tires/Wheels
• Suspension
• Heat mitigation (radiator, oil cooler)
• Oiling system (dry sump tank insert and oil pan baffle)
• Aero
• How to put E85 in your tank when the track doesn't have E85. 91 octane isn't going to cut it at 13:1
• Safety (harness, harness bar etc)

Cam Specs?

With 13:1 compression, can you even drive it on the street with just California gas?

Thanks for the replies! I’m at work dipping strawberries, but when I’m off i’ll update some more with pictures..

BTR 3 Cam
I will be running full E85... or E98 out of a drum if I have too..

Lost me at BTR 3. Why not a custom camshaft?

It was something “quick” while I did my heads cam.. I’m most likely going to call Tony and have him custom spec me a cam.. even though I worked for Engle cams before.. seen you on these forums and Instagram Jay

The BTR 3 will make good power but fall off quick. It's a great cam, just surprised you weren't going custom with this type of build.

I would talk to Cam Motion before Tony, but that's just my opinion.

Pat G, Cam Motion, Ed C, etc before Tony IMO

Get rid of those absolute garbage Pfadt Mounts. Mine had melted on my C5 after 10k miles.

I drive my 12.78:1 static compression ratio NA LS7 in AZ with 91 octane and Torco with zero issues.

Isn't the zr1 pump pwm? So how do you control it since the Z06 ecu doesn't have the control built in?

Hope the build goes well and you get the results you're looking for!!

Tony Mamo put together a nice package for me for road racing if that's the Tony you are talking about. Makes decent power and makes it when it's supposed to over a broad RPM range. He specified the cam in it. Quite frankly I have never seen a better, flatter torque curve which works pretty well for road racing. I have only seen more ( a lot more) from the HPR 468 which is a beast.

If he's helping you it will work great if a road racing track car is your intended purpose.

Oops, lol it’s Z06.

Really? Paid $400 for the set

Yes really. Don't put that trash in your car.

What did you replace them with?

Are they solid mounts? And why not the walbro e85 pump?

My Pfadt engine mounts were melted and deformed so that the motor was basically laying on the orange pedestals.

I replaced them with OEM mounts protected by heat shielding. They have been good for many miles since. I have headers and bolt ons, and I drive the car hard.

Many people here will tell you not to put them on because they have experiences of them bursting. However, this is because no one takes the time to protect the OEM type mount when they add headers and increase proximity to heat.

Sure you could go with a hinson or AMT which is virtually solid and solve the problem, but I dislike the NVH, so I decided not to use them. To each their own.

why a 2012 or later z06 fuel pump?
