Knocked out a Brian Tooley Racing trinity intake manifold install along with a NW103 throttle body on this 2017 Chevy SS sedan. The car already had a ported Ls3 intake, the trinity picked up around 15whp at peak but also added another 1000rpm of usable power out back.

* Notes: This is still on the stock MAF housing which is a pretty good restriction at this point. MAF on the KPA at WOT was 95, no MAF the KPA was 99-100 and the car picked up more power. So we'll be redoing the intake to eliminate the OEM plastic MAF housing.

* Note 2: The trinity will lose a decent amount of low end and midrange. So on an auto car that drag races unless you have a 5k+ converter stick with the stock ls3 manifold, or ported/ported rod mod manifold if you want to keep your short track decent on an all motor car. This car has a pretty wild converter so it'll never be under 5500 at the drag strip and it'll never be under 6000rpm once it makes the first shift.

We'll most likely take it to the track in the next few weeks to run both manifolds back to back. The trinity will most likely MPH harder but the short track might suffer. Sometimes the more MPH out back can make up for a slower short track. As always talk to your tuner about what works best for your combo and goals.

I have a killer deal for you NA LS guys! Pick up a set of new in the box the CNC ported canted valve heads and I'll toss in this open box BTR LS3 Stage 5 V2 cam at a discounted rate. The cam had 0 run time it was used to check some clearances on the engine stand. This is first come first serve I'm not holding it for someone to buy it later. Retail is $3850 after tax. I'll do $3500 picked up cash deal.

The cam fits a SBE 6.2 without fly cutting when using the canted valve heads. If you want to get wild I can toss in a fly cutting tool for $180.

Knocked out a tune on this 6.0 2500. It was pretty gutless on the stock tune especially since it wasn't adjusted for the larger tires. The stock trucks of all generations really pick up decent from some small tuning adjustments.

Knocked out a tune on this 2009 Chevy Silverado after Speed Bean Garage installed a set of Speed Engineering long tube headers on it. The truck already had a Brian Tooley Racing truck cam, and a intake from Airaid Filters to the stock air box.

It put down 329/326 in 2nd gear since it's a 4l60 truck with a stock driveshaft. We weren't trying to do 170mph pulls on the stock driveshaft in the 1:1 gear.
