60mm Wastegate


60mm Wastegate

  • Designed with a two-piece Billet dome made from 6061 aluminum, and a black anodized finish.
  • The piston inside replaces the conventional diaphragm, which is a two-piece serviceable part.  We pressure-tested and rated it for 150 psi working pressure.
  • On our piston we use a Hi-Temp O-ring. We use a nominal O-ring size, so if you have any mishaps replacements are easy.
  • The wastegate valve is constructed from a super alloy mix to handle the hottest and harshest conditions your engine can throw at it. We also use this alloy mix to ensure fuels don't corrode the valve.
  • All reference ports are 1/8 inch npt.
  • Body is casted from stainless steel.

What's Included! 

  • Stainless inlet and outlet flanges
  • Stainless clamps with hardware
  • (3pcs) spring kit (approximate ratings for 5psi , 7psi and 14psi with a combined capability approximating 26psi depending on application)
  • (2pcs) 1/8npt Stainless Barbs
  • (2pcs) 1/8npt Stainless Plugs

Looks like a great quality piece and Fast shipping. I haven’t had a chance to install it yet but can’t wait to see how well it works. Thanks

This is not the first time I’ve ordered from BSI. And it definitely won’t be the last. These guys know what it means to make great products that do the job better than expected

60mm Wastegate on a 10.6:1 6L LS

Figure I would come back after a couple seasons with this gate for a review.
Before 2022 season I made the switch to a single 60mm BSI gate.
I was struggling to maintain low boost on launch and no consistency with my previous 50mm gate.
With the BSI gate I can now maintain 4 lbs at launch if surface is poor with no fluctuations no matter how long I stay on the 2 step.
Down track once at peak boost the boost is just a straight line on the log. The control you have while using this gate paired with CO2 is actually unbelievable.
Highly recommended a BSI gate if you are browsing for wastegates !!

I ran this as a single gate on my 370" LS with a TNT 85/96 and it controlled boost beautifully from 4#-30# without any boost creep!

I'll never again go with a diaphragm gate. After 3 years, thousands of miles, and hundreds of passes this gate worked beautifully but it's an incredible peace of mind that these things come with a spare set of orings in case SHTF
