LOOKING FOR WASTEGATES?!
These are our tried and true BSI Piston designed wastegate. If you are the average weekend warrior or you're looking for the cleanest boost curve for your race car/truck then this is for you.
These have been beat to death by drifters and drag racers alike. We have seen anywhere from 1300F to 2000F continuous temperatures and these do not skip a beat. If you are a diesel tech wondering if these are right for you, check out the numerous high power diesel builds on our social media.
322 ci sbf blow thru carb on c16, 2830lbs race weight @31 psi have been best of 4.72@151mph. Very impressive turbo and it aint even done yet.
I have the TNT 85/96 on my 5.3L '72 Nova. Spools shockingly fast, has ran a best of 134mph at 25psi in 6000DA in 3000lbs car, 1:1 back pressure at this level so plenty left in it if I can get the suspension to work. Highly recommend!
Been using the TNT 92/103 on my daily driven 408ci LS '70 Chevelle all summer. Spools faster than my old VS 88/103 and made 925whp on 15psi with PLENTY more to go. Was picking up close to 60whp per psi until I ran out of fuel system.
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 have twin 45mm gates on a 5.3 with a 98mm gt55 turbo. These control boost amazing from 3lbs to 40 lbs, no boost creep whatsoever. The quality and fit and finish of these are amazing and the customer service is one of the best in the industry.
Fits and functions exactly as it should… made from quality materials
Top notch product as usual
Fast pick up great product,10/10 recommend
Great fitment and quality 10/10
Very nice piece works great
I ordered two different flanges for my S400 from Black Sheep Industries and I have to say that these are by far the best quality flanges on the market! The stainless steel S400 compressor cover outlet to 3.5" tubing fits perfectly inside the cover and the recess for the tubing is spot on. The same goes for the turbine discharge flange to 4" tubing. I will be buying only from these guys from now on! Customer for life here.
These pieces are amazing! I'm putting one on my 4th build this month. These things are absolute jewelry and work amazingly.
If you compare something as small as the clamp to the competitors you'll understand Nick's commitment to excellence
These things are phenomenal! My pre intercooler IAT (under hood temps) dropped almost 40° when I added this blanket. And if your car needs TLC like mine it's incredibly convenient to not have to tap dance around that turbine housing!
Just put one ony new build!
I ran this turbo on my 370" LS street car and was blown away. 3050# car went 5.09 @142 to the 1/8 on 21.5# and that wasn't even stretching it's legs this turbo ran out two walbro 525s on the dyno and would make ALL the boost on the brake (accidentally made 24# in!3.9 seconds)
I'd still be running it today but I decided to go with better heads, more camshaft, and the TNT 92/103
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
