BTR Trinity worth it?
Hey Guys,
My car is a 2013 Grand sport manual It has the A&A supercharger kit with a 3.8 pulley and all the fuel upgrades they offer, along with a blower cam and full exhaust system.
That being said I know the LS3 intake manifold performs very well and I am overall happy with the performance of the car. BTR offered me a partial sponsorship on their Trinity or Equalizer manifold along with valve covers. The looks alone makes it very tempting in combination with the savings.
However, when I spoke to the shop who built the car they said it is not worth it. They claim the after market intake manifolds thrive at 7000+ RPM where as my car is set up to stop around 7,000. That said they said I would likely lose power down low and in the mid section and maybe maintain or gain slightly at peak.
When I let BTR know I would be passing on the deal for this reason they disagreed and said since the car is boosted it may lose slightly down low and in the mid section but gain significantly up top.
I am curious what everyone's thoughts are?

I agree, you would loose bottom and mid torque. It is a short runner intake which is good for high rpm's. BTR's web page even specifies RPM range of 7000 to 8500 for the Trinity.
It does look cool for sure.

Richard Holdener tested it NA on a 427, I think he lost 13ftlbs below peak torque and picked up over 60hp (from being able to rev higher)
I am putting a Trinity on my 408 C5Z, I hate how the LS3 manifold noses over at 6k. Being boosted, you can over come that- but me being NA, I need all the help I can get
Let me see if I can get you that dyno video

The Trinity is an amazing intake if your building a crazy setup. Light weight car you plan to rev up or Big cubes, Big Blower and looking to rev it up over 7k. With a simple cammed LS3 and V3TI what you lose in the mid and low will not offset the peak hp you gain. Your shift recovery will be awful. These intakes are not designed to take advantage of low and mid range. If you plan to keep the boost down below 20psi and want an intake that will make more power then a XS intake would do the trick.

Test engine is a high comp 427 NA with a big cam and trickflow 255 heads
stock ls3 intake. 665hp at around 6400 rpms 598 torque
equalizer intake. 706hp +41hp at around 7500rpm. started passing the ls3 intake at around 6200rpms
trinity intake. 716hp 582 torque +51hp at around 7500. started passing the ls3 intake at around 5900rpms
Here is the video.
Yes the trinity will make more power, and will probably make even more on a forced induction car. Not sure how much time you plan on spending between 6500-7500 rpms. if your drag or roll racing a lot, its definitely worth it. if your a cars and coffee type with a few pulls on the back roads, its probably not worth it. also depends on what kind of a deal your getting.
Id say if you have a ls3 currently, might not be worth it, if your building a ls3 to swap into something and it comes to spending $400-500 on a stock ls3 or $900 on a trinity, its worth it.
Wow, havent seen that one before. So a ported ls3 makes the exact same power as an equalizer, but doesnt lose 40+ under the curve.
