Thanks for looking out for me earlier! LOL. I appreciate it!!!

I know THPSI makes a lid, too, but I think I saw some custom powder coating DSX showed that mimicked the OEM style. I have to look at that and see if I can post a link. It was pretty nice looking.

The lid testing is interesting, because there ARE tests out there that show improvements, going from the shorter-early lid ('Vettes and V3s) to the taller ZL1 (post-'17), and a couple aftermarket ones, too. All validated on dynos'. It seems like the more aggressive the combination, the more it can help improve over the OEM lids, but temperatures are a huge factor, too, since it doesn't take many hits for the 1.7 to get into heat soak. It'd be cool to see data logging on the porting/crossovers/etc to see if there are any improvements. The crossover elimination kit Gabe sells is one that seems to me, could, be the most beneficial as it keeps the inlet/outlets separate, so you're not pre-heating the inlet (if that matters - I would think it probably does).

They do have one that looks identical to the stock ZL1 blower lid, I purchased it when I was still living there and it looked damn near impossible to differentiate the two. I wanted it specifically for getting pulled over and them asking to pop my hood. That may help you with the visual, not sure how everything else you have is hiding, but if you get his guy Stevie Wonder to do your visual you may be ok....

Stevie Wonder. I see we are stuck on that still.

It's easy to pass inspections if you know what their criteria is and what they are looking for. If you are capable of doing a build which satisfies both of those things, the rest falls right into line. If I knew what they are looking for out there in Spain where the OP is at, I could make him a full build and he'd still pass, but for him, I think a nice billet stealth lid is an excellent starting point without overstating the "hey look at me, I'm modified!" factor.

Without getting into the semantics of what Cali is looking for, even if you did get inspected by Stevie Wonder, he's still not deaf, so there's no way you can pass with a CAM. No matter what "build" you create for people that have difficult emissions requirements

Cams are overrated, it's more effective using a larger profile on NA cars like a lot of Gen III and Gen IV LS engines. All that chop at idle means nothing when you introduce FI. It lets you run a considerably smaller profile with less lift to achieve larger power numbers. Not illegal even where he is if you are using a stock cam profile which still allows you to work within the OEM idle parameters of the tune. Plus, in order for them to fail him for having a cam in the car, they would have to be able to prove that there is even one in there which is different from OE in the first place, which without tearing the engine down and using very expensive measuring devices to confirm specs and the profile of the cam, they are not going to do for obvious reasons.

Your potential concern points are dwindling. Your move.

I'm only asking out of curiosity, but what about the tune?... e.g. HPFP parameters, injectors, E85.

And - what about the tune in Spain? Do they look into that, too, or are they just doing a visual? I would have thought CARB-legal-type-stuff would be okay in instances like that, but I wouldn't know for certain. Having an understanding of some of the requirements over there might be helpful in our comments being closer to the topic.

Unfortunately that's not how California works. They don't have to "tear down the engine" to prove that you have a CAM. It's clear that you think you're invincible to this type of stuff until you happen to get pulled over by a rambunctious State Trooper that is willing to prove your car isn't legal to be driven on the road. And unfortunately (as I've seen too many times) it's you against them. And you're not winning no matter how much you bloviate about parameters, and profiles and blah blah blah. CARB checkpoints are becoming more and more prevalent than DUI checkpoints there.

There's no way they could confirm any parameters or even know what the proper parameters are without HPT, the hardware necessary to run and read HPT AND have an OEM tune file on hand to be able to compare the files together in real time. I doubt any and every place out there is going to take the inspection to that level of anality for lack of a better word, but maybe I'm entirely off the mark here and they are that excessive and ridiculous. OP would most likely know the answers to all that.

I believe Radz is asking about YOUR car not that one from Spain.....Radz is in a similar situation in that, he's going to have to smog his car eventually, and although I don't have to worry about that any more, instead of spewing scenarios where "that can't happen, and there's no way they can do this or that" he could use real world answers since you have been able to smog in that god forsaken state "without any issues".

Again - not arguing or anything, because I haven't had to face it yet, but it was my understanding part of the inspection was to compare the file in the car to the file GM submitted, and that ANY change would be caught... Again - I wouldn't know, as that's just what's been posted out there

Full disclosure, and I don't believe I mentioned this to you before, but my registration was due 3 months before moving to the great nation of Texas, I paid the registration and was due a smog check, I failed for my intake, as well as an aftermarket tune on my Magnuson (CARB approval hadn't happened yet). So for those that say they can't check those parameters, they can, and they will enforce it. I had to go to the state ref with my offer letter for my new job in Texas so they could sign off and give me an extension on getting the car registered.

Edit: I was also in LA County, so not sure if that makes a difference.

I see why no one in the forum likes you or talks to you like a decent human being.
