Unless the inspector pulls the intake or exhaust manifolds off the car, how would he know?

 

 

They plug into the OBD 2 port and do a visual. Unless you don’t complete a drive cycle after the swap, the car will never see the sniffer.

Porting heads and running the stock tune will not impact emissions if for some reason you fail the OBD 2 plugin test.

 

I am in Calif.
I do not see how ported heads would fail a smog test.

Vettes now go to STAR stations so it is a visual inspection & ODB reading.
It least in my area they don't put a sniffer up the Vette tailpipes anymore.

A nice blue print of your heads sounds like a great mod.

 

 

I bought some Livernois stage 2 LS2 heads back in the day. They had some very visible engraving on the ends of the heads. That probably wouldn't be a good idea if you're wanting to stay under the radar.

 

Should be fine if all you have is ported heads, since if will be running in closed loop and the ECM is going to try to hold the AFR to 14.7 itself. Hence even if the car is on the rollers for STAR inspection, the tech is not going to WOT the pedal to put the tune into open loop in fear that it will jump the rollers isntead.




As for getting the most out of the motor with the ported heads , it will be WOT conditions where the car is running in open loop on tune alone instead. Here, the tune will keep the motor at about 12.7 AFR in open loop, which will still allow the car to pass a Star test.

 

We can not put that on the heads if its requested for this purpose as well!

 

I showed it big time. You could turn them around and that wouldn't show. I think I put 100K miles on them with your valve springs and no issues. Got my money's worth out of that rig

 

Glad you loved our setup! Its always good to get customer feedback on our products!

 

I understand the CARB is gathering information to enable the test to show if the car has had a tune aftermarket.

Soon even a "tune" as a stand alone mod will be detectable and cause a fail.

At the point I have to eliminate the tune I likely will sell the car.

Got three grandkids and see them almost daily and can not drive the C6 due to no back seat. Always taking at least one of them somewhere. Daughter will not allow them to ride in front seat, which I understand completely.

 

You'd be a perfect candidate for a Chevy SS (the 4 door sedan, not the Camaro SS). Comes with an LS3 under the hood and your choice of manual or auto trans. Mag ride suspension too. Even dual mode NPP style mufflers. If it's not fast enough for you, Whipple and Magnuson both make CARB legal supercharger setups for it. Not sure if there's a centrifugal rig that is CARB friendly.

Chevy SS does sound like a good choice, we are also very known for dealing with those cars and being top knotch experts on some pretty nasty builds for these cars!

 

Interesting car that I never even heard off.

It is ugly but appears to handle very well.

The lack of more refine inside interior, given I am now 70 yrs old, would be a tough pill to swallow.

Production has ended too.
