Livernois Motorsports LS2 Engine Development Testing
Livernois Motorsports has begun doing LS2 engine development on our Super Flow Engine Dynamometer. This test will provide BHP numbers. We will be testing several different combinations using a stock LS2 shortblock with factory GM electronics. We are developing stage 1,2 and 3 camshafts for the LS1-LS2 style engines. We will test LS6-LS2 style cylinder heads in stock configuration, as well as Livernois own LS6-LS2 style CNC version of the cylinder head that was developed with our in house CNC Machine. We will also be testing various aftermarket cylinder heads available to the general public....AFR, All Pro, ET...The results should be useful information to all!!
We have based lined the LS2 engine with 402 hp stock which verifies the GM advertised 405 hp. We’ll be posting the results as we get them throughout the entire test. Please be patient as this test is going to be fit in during our regular work schedule.
Regards,
Rick LeBlanc

Check the customer rides section of their site as well. There are several GM cars (16 or so Corvettes), many with extensive mods.

Below you will find a graph showing the stock Baseline vs. Stage II Livernois Motorsports Camshaft Only. We saw gains of approximatley 80 hp and 20 ft. lbs. Keep in mind these are engine dyno (BHP) numbers and not chassis dyno (RWHP) numbers.

Just to answer some questions I received in pm, the engine does have a set of dyno headers installed, but they were used in the stock baseline as well. The graph was a camshaft and tuning, but the tuning was just to get the A/F where it was in the baseline. (no other nolt-on's)
We will be testing our own CNC heads, Darts, and ETP's very shortly.

Below you will find a graph showing the Stage II Livernois Motorsports Camshaft Only vs. Stage II Livernois Motorsports Camshaft and Stage I Livernois Motorsports CNC LS2/LS6 Cylinder Heads. We saw gains of approximatley 30 hp and 20 ft. lbs. with the heads. This puts us at + 110 hp and + 40 ft. lbs. over the stock baseline.
These LS6 heads will be available fully ported and assembled very shortly for under $1,000!

Great results!
One suggestion though: Lose the 'curve smoothing' program. Real engines have bumps and dips in the torque curve and without them showing on the graph, the credibility of the results is undermined . (In this case of course, the raw data is visible underneath.)
