LS Engine Power Packages - LS1 and LS2 Power Recipes. How good are the Gen 3 V- 8s?

Compared to the original Gen 1 (2. That list of everything includes power and torque, fuel mileage, and even reduced emissions. Also missing is engine weight, as the LS1/LS2 engines feature not only aluminum blocks and heads, but also composite intake manifolds. Imagine the response you'd get back in the 1.

Now toss in a set of heads that flow more than even ported 2. L LS1 (or 6. 0. L LS2) to both sip fuel and optimize power production at every throttle angle. And the new LS3 is better still with 6. Following in the footsteps of the original, the LS1/LS2 motors respond equally well to performance mods. Given that time and technology march on, it should come as no surprise that the LS1 heads flow much better than even the trick fuelie heads of yesteryear. While the stock components have improved, so too have the aftermarket versions, as flow figures from a set of ported or aftermarket CNC heads for the LS- series motors easily exceed the magical 3.

These are flow numbers only dreamed about by stock 2. Only a handful of aftermarket 2. LS heads. Naturally stock LS- series motors also respond well to cam changes. Since it's unnecessary to remove the intake manifold (and distributor) to facilitate lifter removal on the LS- series motors, cam changes on the LS1 and LS2 are a snap.

Simply rotating the cam will push the stock hydraulic roller lifters up and out of the way to be retained by the factory plastic guides. Since the stock components were designed to produce a given amount of power, it's not surprising that aftermarket components can improve an LS1's or LS2's power output. Like all the previous small- blocks, there is power to be had from an intake swap. For LS1 and LS2 motors, the hot setup is actually the factory LS6 intake, though in the case of the LS2 it is necessary to step down in throttle body size.

Mini is apparently finally out testing the long-rumored hot-hatch with over 300 horsepower on the Nürburgring, and it sounds great. It seems we’ll be getting Mini.

Prepping Our Fourth-Gen For Boost: SPEC Super Twin Clutch Install. This month’s installment of Horsepower! Lou Rotella Read More.

An explanation of the difference between gross horsepower and net horsepower and an effort to clear up some common misconceptions about the two.

There are a number of other intakes available for the LS- series motors (with more on the way), including carbureted combinations from Edelbrock and GM Performance Parts. Headers are a solid performance upgrade, as are the old standbys like nitrous oxide and forced induction. Add an NOS nitrous kit to even a stock LS1 and you're talking about some serious power. Add it to a modified motor and you're running 1. The same goes for blowers and turbos, as both the LS1 and LS2 respond very well to boost. Even in emissions- legal trim, a blown LS1 will pump out over 5.

With turbo motors, the sky is the limit, as 1,0. To illustrate the power available from the LS1 and LS2, we gathered together a number of combinations, ranging from 4. Since buildups most often include a power goal, we decided to provide LS1 and LS2 recipes to reach 4.

It's obviously possible to eclipse these numbers, but we thought these power levels best represent what can still be construed as real street motors. In most cases, we started with a stock LS1 or LS2 crate motor from GM Performance Parts, so these buildups began with what a Camaro, Corvette, or truck owner might currently have under the hood. Since the LS- series crate motors are so popular for street rod and street machine buildups, the recipes illustrate what's possible with modifications to the basic motor. Check out the ease at which serious power is obtained from the LS series and you may rethink stuffing an original small- block in that Camaro, Nova, or Chevelle project.

Spec Sheet 4. 00hp LS2. Suzuki Alstare Extreme Racing 2000 Pc Games on this page. Take one 4. 00hp LS2 and install it on the dyno and you have an easy 4.

For this test we equipped the LS2 with Hooker headers and an open exhaust. With optimized air/fuel and timing curves, the LS2 pumped out 4.

If you think extracting 4. LS1 was easy, things get downright simple with the larger LS2. Given its factory rating of 4. LS2 produced 4. 62 hp and 4.

Hooker headers. Compared to the smaller LS1, the LS2 offered not only more peak power, but also more power throughout the rev range. Down at 3,1. 00 rpm, the LS2 produced nearly 6. Spec Sheet 5. 00hp LS1.

Total Engine Airflow supplied a set of ported 5. L truck heads. When combined with a small Comp cam and FAST LSX intake, the result was 5. As impressive as the Gen 3 motors are in stock trim, they're even more so once modified. Using the same LS1 crate motor as a starting point, eclipsing the 5. LS6 intake would also work well at this power level. The LS1 was treated to a set of ported 5. L truck heads from Total Engine Airflow, a Comp XR2.

HR cam, and a FAST LSX intake. The smaller combustion chambers (6. L heads increased the compression ratio by . When combined with the mild cam and LSX intake, the result was 5. Note that the power curve was still climbing at our shutoff point of 6,2.

Spec Sheet 5. 00hp LS2. The CNC- ported AFR 2. LS2 produced such big power. Combining the free- flowing heads with a custom AFR- spec cam resulted in 5. Like the smaller LS1, the 6.

L LS2 responded just as well to modifications. By equipping the LS2 crate motor with a set of AFR 2. AFR cam profile, and an LSX (9. Remember that the LS2 motors sport the better LS6 heads (2. LS1. With 5. 71 hp, this is one serious normally aspirated street motor. Spec Sheet 6. 00hp LS1.

It's obviously possible to exceed 6. LS1, but life is so much easier with forced induction. Rather than go the wild cam, high- compression, or even large- displacement route, simply adding a supercharger to an otherwise mild LS1 will result in some serious power. Exceeding 6. 00 flywheel horsepower is no problem; in fact, this modified LS1 managed to exceed 6. Credit the efficiency and power potential of the Kenne Bell twin- screw supercharger for the impressive power. The test motor featured a 5. L LS1 short- block equipped with LS6 heads and cam.

The motor exhaled through the stock LS6 titanium exhaust. Run on the Dynojet chassis dyno, the Kenne Bell supercharged Vette produced 6. How does 5. 00 lb- ft of torque at just 2,0.

If you put your foot in this bad boy's throttle, you'd better be sure the wheels are pointed in the right direction. Adding a Kenne Bell supercharger kit to your C5 or C5 Corvette is a surefire recipe for performance. Running the kit on an LS6- enhanced LS1 resulted in 6. Adding the same kit (with more boost) to a 4. Spec Sheet 6. 00hp LS2. Given the impressive starting point, exceeding 6.

L LS2 is every bit as easy, especially when you introduce a little nitrous oxide to the mix. Running a set of Trick Flow Specialties CNC- ported LS1 heads, a small Crane Z- series cam (2. Hooker headers, the mild LS2 produced 5.

After adding the NOS plate system to the mix, the peak power numbers jumped to 6. The transition from a mild (albeit powerful) 5.

The instantaneous thrust of torque offered by the NOS kit is seriously addictive. Whether stock or modified, nitrous oxide can add power to any combination. We installed an NOS plate system on an LS2 equipped with Trick Flow CNC- ported LS1 heads, a small Crane cam, and Hooker headers. The Lost Inca Prophecy Setup Outlook.

Adding the NOS kit to the modified LS2 motor resulted in 6. Spec Sheet 7. 00hp LS1. The twin turbo kit from HP Performance was installed on the engine and then into a C5 Vette with excellent results. Running 1. 3 psi, the turbocharged LS1 stroker produced 7. The same HP kit has been used with 6. What power recipe story would be complete without a turbo system? Extracting 7. 00 horsepower from a 6.

L LS1 is not particularly difficult, but having that power come in a driveable combination makes life somewhat more difficult. The challenge is overcome with boost, in this case from a twin turbo kit from HP Performance. HP combined its intercooled twin (5. L truck block), a set of AFR 2. FAST LSX intake to produce 7. These power numbers came at a peak boost pressure of 1.

Note that 7. 06 wheel horsepower translates into something near 8. LS1 indeed. Spec Sheet 7. LS2. Running a mild Lunati Voodoo cam, a set of Trick Flow CNC- ported LS1 heads, and a FAST LSX intake, the Vortech supercharged LS2 produced 7.
