For those viewers adjusting this bypass, there are a few ways shown on TH-cam on how to adjust this. The service manual actually shows a 1-1.5mm preload on the stop screw. This is to prevent the boost end of the actuator circuit from smashing the butterfly actuator plate into the housing. The screw should be contacting the lever. Just grabbing the diaphram and twisting the can isn't the proper way to trim this out and can actually cause damage over time due to the butterfly biting into the aluminum housing. A little disassembly and careful adjustments will provide the desired result while minimizing the chance of damage. I did mine by removing the throttle body and using my finger to feel the position of the actuator plate, I can feel that the butterfly plate is fully closed and by visual see where to adjust the diaphram so that the actuator rod is in proper alignment and not cocked. I then tightened the hold down bolts. After the bolts were torqued, I adjusted the stop screw just until I saw the lever move, basically no preload....yea I know, not what the manual says, but if you did the 1-1.5mm preload, you would see the actuator plate slightly open which is what we're trying to eliminate right?

I bought my ex-wife a 2015 ZL1 in hawaii cuz thats where we are from but now live in the states. I always had a check engine light. Never thought to much about till we moved to the states a few months after purchase. It had an after market intake, put it on the dyno to see what was wrong some reason the aftermarket intake system was throwing the code. So me and the turner decided to go back to the stock air filter intake. Than finally the light went away and gave me an even 525hp 525trq, i just did a routine maintenance of oil because even in 2022 it just made over 36k and yes 36k. Bone stock, oh and its an auto 6spd cuz she cant drive manual the car was for her anyways its her dream car mahalo and aloha 🤙🏽🤙🏽🤙🏽
Was that 81 south by chance.. PA is beautiful. Family moved there when I was 14.. think about PA daily Cold Spring Creek trail up past Fort Indian town Gap.. great fishing
good job man keep it up your channel will grow much further considering you actually do multiple car builds that you don't own, but you do all the work on
You must have a freak ZL1, I work at a performance shop in Arizona and work on nothing but ZL1s, Camaros , Corvettes, CTS-Vs. I have never seen a ZL1 dyno that high ever stock. Either that or the numbers were being fluffed since I didn’t see SAE on it.
it won't hurt the engine but...how about the argument that the reason there's a gap is the hardened flap will eat into the soft aluminum and eventually have a crazy leak that you can't then tighten up again?
HeadGames motorworks in NJ does the best porting around hands down....worth checking out if you are gonna keep porting blowers and stuff. I personally wouldnt touch the heads cause the port is already huge and they seem to run out of blower much before the heads are at their limit. I respect your positive energy and the want to get your business grown!! keep up the good work
Ok idk why but the volume on this vid is stuck all the way up, I try to turn it down and the volume thing pops up and says its on silent but it doesn't change the actual sound idk
Oh just saw u said air fuel was as little leaner! So I guess my question is, is this safe to run on in this fashion being a bit leaner? Would you suggest doing this if I did not get a tune??
Andy, if I were to do this bypass valve mod and a Roto-Fab Cold Air intake (CAI) at the same time, would the lean condition from the bypass valve mod be balanced out by the additional air from the CAI mod?

Awesome car brother I just bought a 2013 ZL1 30,000 Owned by a police officer unmolested never been upgraded no intake no pulleys pure stock

2 videos one day? FUCK YEAH
+Tyler Chambers you're welcome
Was that 81 south by chance..
PA is beautiful. Family moved there when I was 14.. think about PA daily
Cold Spring Creek trail up past Fort Indian town Gap.. great fishing
You're turning into the ZL1 guru boss. Thanks for the content.
Can you show us how to do it instead of just talking
good job man keep it up your channel will grow much further considering you actually do multiple car builds that you don't own, but you do all the work on

East coast air boss
@@DiabloFormulaRacing guess I need to move to the east coast. I’m sure having 93 instead of 91 helps too.

Can u do the bypass on the ctsv 2017 lt4 that's already modded
What!! 2 videos in ONE DAY? You're the man Andy'
Great video Andy!...she had something special right from the start...when you're done with her she's going to be awesome brother....can't wait to see!
Please do a HOW TO on this mod!!!!!!!!!!!!!!
I'm not getting any luck finding a video on how to do this for my 2013 zl1, any chance of a reference URL or video?
Guys been doing this boost bypass mod on the 03/04 cobras too from back in the day. You would just swap around two vacuum lines.

awesome dyno my ZL1 2015 Recaro seats stock same power stock manual transmission
What do you think about 14' zl1's vs. 14' gt500? In terms of stock, modding costs, and built cars such as Nicks?
Just saw Cletus dyno an lt4 zl1 stock it only made 519hp but then just a pulley and cold air and it made 612hp
They Lt4 will run around 560 to 568 on the dyno.
nice! so are you suggesting to do a tune with this mod since it runs leaner?
Will this effect reliability? Is there any downsides to this?
ZoHBo yeah... when the blower isn’t under boost it builds up crazy amounts of heat.
You would think the engine builder would do these adjustments at assembly!
can you do the mod to the Cts V's lsa??
+RTA MOTORSPORTS yes you can
Ok idk why but the volume on this vid is stuck all the way up, I try to turn it down and the volume thing pops up and says its on silent but it doesn't change the actual sound idk
5000+ subscribers!! I'll be here when you reach 50 000.
+jaypee1313 awesome....looking forward to it boss!!
Hell yeah Andy. Keep up the great work............And auto pickup service as well.......Wow
I like that color combo
Are automatics the same doing this?
will this work on the 6th gen ZL1 1LEs?
Unfortunately it will not
@@DiabloFormulaRacing pain
How do you get more whine out of that LSA blower ?
Use a Harrop cold air intake 👍
congrats on 5k subs!!! looking forward to watching your shop expand as more and more customers roll in!!!
Can closing the bypass valve on a supercharger damage the engine, I was told that it would?
+Kenneth Palazola it won't
DiabloFormulaRacing do you need a tune to do this mod ?
my 1979 black camaro has 1290 Hp to the tires. Spent my life saving on the piece of crap
Why did the supercharger cover say LSR and not ZL1?
Richard Miller it's says lsa noob
The car is completely stock it’s soo beautiful. So we’re going to mod the hell out of it 😂
What should the Air/Fuel Mixture be set to after this mod?
+Kevin Lewandowski 12.0 at the leanest
Much Appreciated! Thanks.
I wanna zl1 now
Does anyone know if this will destroy the engine over time?
It will not
@@DiabloFormulaRacing
Thanks - it was just referenced to get a tune afterward and it made me think.
Best videos on TH-cam. Is this your car?? Going to be a beast.
Deplorable #2,950,000 no he runs a performance shop and its for a customer , one of a now total of 4 zl1's coming to his shop in recent times
Oh just saw u said air fuel was as little leaner! So I guess my question is, is this safe to run on in this fashion being a bit leaner? Would you suggest doing this if I did not get a tune??
how much wheel horsepower can a tr6060 handle
Bmackins94 enough :P
Bmackins94 700whp stock
Great job👍🏾
I need them seats in mine
BADASS MOD gotta try it thanks!!!
the ZL1 is amazing is a monster 5 Gen the new ZL1 LT4 646 hp 635 torque already stock will have
+George Giannopoulos ZL1 2015 2017 can't wait pull power out of one of the 6th gens!!
Are you from Mexico or USA
+George Giannopoulos ZL1 2015 2017 Pennsylvania, USA
What do you think the new ZL1 LT4 stock 645 hp 635 torque ? 10 speeds
+George Giannopoulos ZL1 2015 2017 I think it's going to be an awesome car
street speed 717 brought me here!
Since when does a ZL1 say Camaro on it??
Did the air fuel ratio change or need to be adjusted before and after???
It did get slightly leaner so tuning would be recommended with this mod.
Andy, if I were to do this bypass valve mod and a Roto-Fab Cold Air intake (CAI) at the same time, would the lean condition from the bypass valve mod be balanced out by the additional air from the CAI mod?
@@JasonJolo98 lean fuel mixture plus more air from the intake equals even leaner mixture
Doing great Andy, wish I could bring my GT to the shop🤘🏼🔥
Does this need tuning ?
hahahahaha, I just did this to my V today.
Conatus did it work? Any issues? Did it need a retune?
Does this mod do anything to durability?
+Skip Hedgepath nope, I'd just double check air/fuel to make sure its still safe
This video does not show hot to make the adjustment, its a waste of time
Great
all i seen was free zl1 i clicked so free but it was free zl1 hp
Wow !!
hey man awsome vids keep it up i got a shelby gt500 for all those slow ass ZL1 hahahha
