Chevrolet Engine

Forged Internals Support More Boost!

For builders who want to stretch the performance of a turbocharged or supercharged combination, the Chevrolet PerformanceLSXB15crate engine is the foundation they need! Its durable, all-forged rotating assembly supports up to 15 pounds of boost. Our ratings of hp and lb.-ft. are only an indication fo what the LSXB15 is capable of.

ChevyPerformance engineers began with an LS Bowtie standard block and added forged crankshaft, connecting rods and pistons. The short block assembly was then topped off with high-flow, LSX-LS3 6-bolt rectangular-port heads to create an affordable foundation for supercharged and turbocharged combinations. GM delivers the LSXB15 without an intake manifold and other accessories, allowing you to tailor the induction system and other features to suit the forced-induction setup of your choice.

Our horsepower and torque ratings are based on testing with the production-style, normally aspirated fuel injection system. The power you make with a supercharger or turbo will vary.

Make 1, HP With an LSX Crate Engine and a 76mm Precision Turbo

| How-To - Engine and Drivetrain

Begging for Boost

The LSXB15 crate engine has proven itself to be not only a capable performer but an LS platform literally begging for boost. Advertised by Chevrolet Performance to accept "up to 15 psi of boost" (thus the 15 in B15), we can say with absolute certainty that their suggested boost limitations were wildly conservative. In our last adventure with the B15, we pumped up the pressure to nearly 29 psi, effectively doubling the limit suggested by GM. The boosted B15 more than just survived, it thrived. After running multiple cam profiles with a L Whipple supercharger, we eventually cranked up the boost and made nearly 1, hp before belt slippage stepped in to ruin the pressure party. Though there was more power to be had with the twin-screw setup, we switch gears by swapping out the Whipple for a brand-new boost builder. Enter the turbocharged B15!

In truth, the B15 couldn't care less where the boost came from, but there were decided differences between the boost offered by a supercharger and a turbocharger. The major difference between the two methods of forced induction was the energy used to develop said boost. On a typical twin-screw supercharger, the rotors are driven directly off the crankshaft. Much like other accessories (AC, power steering, or alternator), there are parasitic losses associated with driving the supercharger. The higher the power and boost level, the greater the power losses associated with driving the supercharger. That power is actually produced by the engine, but, unfortunately, absorbed by the blower. The end result is that the power is neither registered on the dyno nor available to accelerate your vehicle. By contrast, the turbo is driven off exhaust energy and, unless backpressure is excessively high, the losses associated with driving the impeller are minimal. A turbo will usually produce more power per pound of boost than a typical supercharger, with that differential increasing with pressure and output.

Excited that the turbo offered more power potential on paper, we were anxious to apply that theoretical power to the B15 crate motor. To prepare for turbo boost, we replaced the Whipple supercharger and dedicated blower cam with a Holley Hi-Ram intake and Stage 3 turbo cam from Brian Tooley Racing. The single-turbo system consisted of a pair of turbo manifolds (tubular headers) from DNA Motoring combined with a custom Y-pipe designed to accept a T4 flange. Looking for nothing less than four-digit power levels, we selected a 76mm Precision turbocharger. The PT featured a 76mm compressor wheel, GTstyle compressor housing with a V-band discharge flange, and a 75mm (84 trim) turbine wheel. We started out with the A/R exhaust housing, but ultimately switched to the larger housing. Boost from the Precision turbo was fed through an air-to-water intercooler from CX Racing and controlled by a pair of Turbo Smart wastegates using their manual controller. The final touches included larger injectors controlled by a Holley Dominator EFI system.

It was obvious right off the bat that the B was begging for boost, as the turbocharged LSX immediately belted out impressive power numbers. Running just psi at the power peak, the turbocharged LS produced hp and lb-ft of torque. In a perfect world, the wastegates would maintain a flat boost curve once the motor came up on boost, but our system produced a falling boost curve. The culprit was likely excessive backpressure in the single-turbo system, because the wastegate functions when boost overrides the supplied wastegate spring pressure. Unfortunately, the backpressure applied to the wastegate valve combines with the boost supplied to the diaphragm to prematurely open the wastegate and excessive (or ever-increasing) backpressure makes life difficult for proper boost control. Regardless, the turbo B15 still produced amazing power, with hp coming at psi then 1, hp at psi. After eclipsing the 1,hp mark, you'd think we would be satisfied, but we had a B15 just begging for more boost. Since the amazing little crate motor shrugged off all the abuse from our single turbo, maybe next time we need to hit this thing with multiple power-adders.

Single Turbo LSX vs. vs. psi
Raising the boost pressure supplied by the turbo had a positive effect on power. Equipped with the Brian Tooley Racing Stage 3 turbo cam and Holley Hi Ram intake, the turbocharged LSX produced hp and lb-ft of torque at psi. Stepping up the boost to psi resulted in a jump to hp and lb-ft. The final run netted 1, hp and lb-ft of torque at a boost pressure of (see boost curves). With a consistent boost curve, the peak power number would be even greater, but we were within hp of the flow limit of the single turbo, so what this LSX motor really needed to make more power was a twin-turbo setup.

Single Turbo LSX Boost Curves vs. vs. psi
As evident by the graph, the single-turbo system produced a falling boost curve. The hp, psi run (bottom) actually started out with psi, then rose slightly to psi before dropping off to a low of psi at the power peak. The subsequent runs at higher boost produced similar curves. The hp, psi run (middle) started out at psi, rose to psi, then fell off rapidly to just psi. The final 1,hp (top) run continued the trend, starting at psi before dropping down to psi. Data logging showed the backpressure to exceed boost pressure by more than 10 psi (and climbing) at the power peak.

TURBO GM B15 LSX CRATE MOTOR-1000+ HP \u0026 A/R CHANGE
I blew up my engine and I need a new one now.


Which one one would you choose (B15 is ~2k cheaper)?


I am planning to run it with a base AGP TT kit and stock driveline to make whp until I upgrade my driveline and fueling. After that I might shoot for whp.


One of my concerns is that will produce too much power for my clutch and tranny to survive even with weakest lbs springs. Will it?
