VS RACING GEN3 PISTON STYLE WASTEGATE REVIEW 

Awesome, thank you!

Zero boost issues since we switched to onboard air. Matter of fact the original setup is working so well now that I never even put these VS Racing gates on and am thinking about just selling them. The problem, as several people already guessed, was actually the oversensitive 4port mac valve. Now that it’s out of the equation the boost control is working flawlessly and buttery smooth. Check out the newer videos for more info.

Seem to be doing pretty well. The black sheep industries gates are the same setup and have been out for a few years now with a fantastic reputation.

@@BadLuckGarage that’s awesome. If mine ever fails, I may look into these. I have a tial right now, I learned my overboost lesson with eBay cheapies.

They’re actually exact knockoffs of the JGS gates that Motion Raceworks sells for $500, not the BSI gates. I corrected that in a pinned comment after seeing the JGS gates in person.

Thanks for the information! I love the piston setup vs a rubber diaphragm. Im building a twin vsracing 7875 gbody and was looking for a nice set of gates for a while

@@Carolina_Squid Hell yea! Sounds beastly!😈

Usually yes when dealing with open loop boost control or just a set boost pressure. When using closed loop boost control as we’re doing it can lead to erratic surging as the ecu tried to catch the overboost and pull DC from the MAC valve causing the boost to fluctuate up and down as you can see in the last track day video. However in recent testing when I take the boost controller out of the equation and just run on gate pressure I have zero boost creep issues which tells me the wastegate placement isn’t the issue at all. I just don’t think using a 4-port and fluctuating compressor air as a reference is going to work out. So we’re switching over to an onboard air setup within the next week or two instead of continuing to fight this current setup.

Never ended up using these. After switching to onboard air boost control everything worked perfectly with our old $60 eBay gates. I’ve actually been meaning to sell these since I don’t need them anymore.

@@BadLuckGaragewanna sell these to me ill buy em

Good to hear! Hopefully I’ll have a similar experience because 3-4lbs is what I want on gate.

Good idea!!😄

@@BadLuckGarage 🤣😁

Thanks for watching. Glad this video helped you out!

@@BadLuckGarage Well I was trying to help you out do not waste your money By the original.

@@PontiacLS Thanks for watching. Glad this video helped you out!

No that should be correct. Make sure the valve is going all the way down and sealing against the fire ring. If it’s not then get ahold of Viren and have him send you a replacement.

@@BadLuckGarage it’s both of them, I’m assuming I’m creating more pressure at idle than the 4lb can handle? Possibly opening it just a little, running 2.5” exhaust to each turbo.

@@olddirtycougar6401 you shouldn’t be creating enough backpressure in the hotside at idle to open 4lb springs unless you’ve got a serious restriction somewhere. There’s definitely something not working correctly in that setup. Have you tried the stiffer springs?

@@BadLuckGarage it’s a rear mount turbo, I haven’t I’m unfortunately still waiting for my stroker kit so I have my 52 year old stock motor currently, I don’t feel comfortable enough to increase the spring pressure. Was more about getting everything set up and ready prior to the 408 going in

@@olddirtycougar6401 Well you need to figure out where the restriction is now, because if the stock engine is creating that much back pressure the 408 with more exhaust volume is only going to make the situation worse.
