2006 Chevrolet Corvette Z06 Dyno Results with GPI Heads / Cam!

The Sad Story.

This Z06 came to us after a very unfortunate “high RPM event”.  We are told it was trailered all the way from Mexico to see us, but sadly – the situation was pretty bad.  The internals of the motor look to have been used in a Blendtec commercial – suffice to say, it was time for some GPI love.

The LS7 in the car was the original unit from the factory, and in nearly virgin state – with only an intake and a set of headers.  Previous to the “incident” the car put down 480rwhp on the dyno – so we will use this as the baseline.

The Build.

First, we sourced an LS7 short block – installed a custom street grind GPI Camshaft and a set of GPI Cylinder Heads before reinstalling the Airaid Intake as well as the Kooks headers that were on the car when we received it.  After a couple of days assembling and installing – it was off to the dyno to get the car dialed in, and see what kind of gains we could achieve with a simple GPI Cam and Heads on an LS7.

The results are in!

This car retains nearly stock driveability, and will offer incredible durability as a naturally aspirated powerplant. 

When comparing results back to back – the GPI Cylinder Heads and GPI Camshaft combo were able to add 90 rwhp, which has dramatically changed the overall character of this car!

The owner is very happy to have his baby back, and we are on to the next project!

DO I HAVE A CREDIT LIMIT WITH AFFIRM?


Unlike a credit card, Affirm is not a revolving line of credit. While customers can take out multiple Affirm loans at once, each Affirm loan application is evaluated separately as a closed-end transaction. An application from a returning customer may be denied, however, if that customer has failed to repay other Affirm loans on time or if the customer shows excessive borrowing behavior.

HOW DO I PAY MY BILLS?


You can pay your Affirm bills online at www.affirm.com/pay. They accept payment by debit card, bank transfer and check.

DOES AFFIRM PERFORM A CREDIT CHECK?


Yes, when you first create an Affirm account, Affirm perform a ‘soft’ credit check to help verify your identity and determine your eligibility for financing. This ‘soft’ credit check will not affect your credit score.

WHY WAS I PROMPTED TO PAY A DOWN PAYMENT WITH A DEBIT CARD?


Affirms tries hard to approve every purchase but sometimes can’t approve the full amount. When this happens, Affirm provides a debit card down payment option so that you may still complete your purchase right away.

WHY WAS I PROMPTED FOR A CHECKING ACCOUNT?


Affirm sometimes requires additional information to consider a credit application. Such information may include an active checking account, which helps Affirm verify your identity and your ability to repay the requested loan. If they prompt you for this information but you are unable to provide it, Affirm will be unable to approve your credit application.
