With An 11-2d Timeslip In Manus, We Get More Serious With The '10 Camaro By Upgrading The Heads, Cam, And Exhaust
Last month, HOT ROD embarked on a mission to run 11s with a brand-new '10 Camaro SS. With a few bolt-ons, Nitto 555R elevate radials, and a shot of nitrous, the HOT ROD test car blistered to a best of xi.96 at 115 mph. On the chassis dyno, it kicked out 514 rwhp (on the sauce), up from the stock numbers of 374 rwhp. Off the bottle, the bolt-ons were worth 23 hp and made 397 rwhp. After some practice on the dragstrip, car owner Robin Lawrence power-shifted his fashion to a best of 12.73 at 108 mph-sans nitrous. This month, nosotros want to see how fast nosotros tin can arrive in naturally aspirated trim.
The LS3 is great in its stock form-it has 376 ci, free-flowing heads, and a salubrious hydraulic roller camshaft. Last month's bolt-ons were shorty headers, an beam-back exhaust, and an Abaco cold-air kit and MAF sensor. This calendar month we get more than serious with a head, cam, and header bandy. The heads are GM Performance Parts L92 CNC-ported (PN 88958698) castings. Subsequently porting, they have maximum intake catamenia of 330 cfm, and the frazzle ports motility 201 cfm, both at 0.600-inch elevator and using stock 2.165/ane.590 valves.
We called the stock cam healthy because it comes from the factory with 0.551/0.522-inch elevator and 204/211 degrees of duration at 0.050 lift, but nosotros wanted more. The first ane on the test list was the GMPP LS Hot Cam (PN 88958733). Information technology features intake and exhaust lift of 0.525, merely the duration is more than stock with 219/228 degrees. The lobe separation is listed as 112 degrees, giving the engine a nice idle: a little lumpy only livable. Why would nosotros exam a cam with less elevator than stock? First, we have seen a few people online become this camshaft installed by their dealers. Second, our nastier Lunati Voodoo cam hadn't come in yet and nosotros couldn't sit still with zero to exercise.
The CNC-ported heads and Hot Cam brought power to 406 rwhp, hardly impressive for the modifications. Our assumption is that the restrictive exhaust-thanks to the four catalytic converters-is holding it back. When Lawrence added directly test pipes in place of the manufactory units, information technology was worth 23 rwhp. Our overall output was upward to 429 rwhp and 415 rear-bicycle torque.
When the new cam showed up, Lawrence yanked out the Hot Cam and stuck in the Lunati Voodoo cam, which has 0.578/0.598 lift, 233/245 degrees of elapsing, and a lobe separation of 115 degrees-more ambitious just still completely streetworthy with nice idle characteristics, polish low-rpm driveability, and healthy depression-end power. On the chassis dyno, the Camaro spun the rollers to the tune of 448 rwhp and 416 rear-bicycle torque.
At that point, the shorty headers were more than than probable choking the engine, then we swapped them for some long tubes from Kooks Custom Headers. Kooks also sent a 3-inch cross-pipage, which mates to a new 3-inch Kooks after-cat exhaust. The easier breathing was worth another nineteen peak rear-cycle horsepower, and the midrange ability went up as high every bit 25 rwhp in some spots. "The machine feels similar it has another 75 hp," Lawrence says-manifestly a bit exaggerated, but a few quick blasts on the street showed the seat-of-the-pants feel was greatly increased.
On the track, we swapped to Mickey Thompson 305/35R18 ET Street Radial tires on C6 Z06 wheels. The stickier tires proved to exist the hot ticket, as Lawrence left at half dozen,000 rpm, banged the gears at vi,200, and flew the traps with a 12.x at 115 mph (without nitrous). One stab of the juice and the story changed dramatically. Our new rear rubber was blown away instantly and got loose on every gearshift. It slowed the HOT ROD Camaro down big time to just a 12.twenty, merely it blistered the traps at 125 mph, showing real potential once we can get the machine to hook ameliorate.
