When it comes to performance and horsepower, the engineers at SLP are at the vanguard of innovation and proven results. This year at SEMA 2015, we had the opportunity of speaking with Greg Banish, Powertrain Development Manager for Street Legal Performance (SLP), and Roush Performance.
During our interview, Banish introduced us to SLP’s new Performance Pacs for 2010 to 2015 Chevy Camaro SS, equipped with the 6.2L V8, LS3; and L99 engines, and new Cold Air Intake Kits for 2014 and 2015 GM Trucks equipped with the 5.3-liter and 6.2-liter V8 engines. The SLP Performance Pac comes with the SLP LoudMouth Exhaust Kit, SLP Blackwing Cold Air Kit, and the SCT X4 Handheld Flash Device.
“We did some subtle changes to the design intake on the 5th Generation Camaro LS3 Package, and we learned a lot about it in the process,” says Banish.
Even on the entry level low-boost kit, SLP’s Performance Pac picked up an additional 20 rear-wheel horsepower without doing a pulley change. The kit offers a serious improvement to the airflow that allows for better use of the intercooler, and it showed on the chassis dyno tests.
“We installed the Performance Pac in our Camaro and ran a power test to get it hot. Is this durable? Can our customers expect this to work for them? The answer was a resounding yes. We even ran it in a customer’s ’67 Camaro with an LS engine swap and the same supercharger package and outfit kit. His 6.0-liter LSX still made more than 700 rear-wheel horsepower on regular pump gas. So, we’re really showing that the core of our TVS2300 Supercharger really can support pretty big horsepower,” Banish said.
Now the engineers at SLP are thinking, “If we take it out of the LS and put it in the new LT1 Corvette engine, what can we expect from it?”
We can’t wait to find out.
“We want an entry-level 50-state legal kit,” Banish added. “A lot of customers in California need that executive number (EO), and also want room to grow. We want to make sure our kits support that growth in the future, and the clean-sheet design that we are doing for the Corvette C7 is for those same reasons.”
The lessons that we’ve learned on what improves flow on the LS kit translate very directly to the Corvette 6.2L engine family. — Greg Banish, SLP
“We’re not just an aftermarket performance company. We do serious engineering work, we have flow and fuel labs and we use those tools to develop our products. The SLP customer gets the benefit of that,” he continued.
As a standard process, SLP runs engineering data on all their projects, allowing for consistency on how they test and manufacture their products.
SLP is developing something new for the LT1 and LT4.
“We will have a designed kit that the LT1 guys can just bolt on, add more power and basically get to the limit of what their fuel systems can deliver,” he said. “The GM LT4 gave us the TVS1740 as the base compressor, and though they spin it faster, it gets hotter.”
SLP wants to develop an upgrade that is bigger and better than the 1740 with an LT4 version of the kit that will help support the extra power.
Suzie Bauter also who gave us an inside scoop on the red Camaro displayed at the booth, a tribute vehicle built by Team Red Camaro. “It is complete with as much as we could get a 5th Generation Camaro to look like the Big Red Camaro “Original Outlaw Racer,” and perform like it,” she stated.
“Big Red” debuts SLP’s new Supercharger for the LS7 7.0-liter engine. It also boasts a full suspension upgrade, custom wheels, custom interior, custom paint, and badging. It will be auctioned to benefit the Ride 2 Recovery veterans charity. What better way to wrap up all the exciting news from our friends at SLP?
