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

effort & time will be appreciated just keep us updated man !!

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 has 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.

So it made 402bhp w/ headers?
I'll be waiting for the dart #s. i still havent seen actual flow #s from the darts.
I would assume you will be using the same chamber size/head size for the comparisons? or semi-similar at least?

Brandon, the 402 BHP was indeed with the dyno headers, which are a mid-length type header. This may show slightly better numbers, but our comparison was to show the gains between different head and cam combinations. The stock numbers were purely for a number to baseline from.
We are trying to keep the everything as close as possible and I'll make sure to post exactly what head sizes we use.

Damn...that cam sure held on to the torque really well...thanks for doing this test guys. This is the kinda info this community needs...a nice, repeatable test that shows the facts.

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!

SAE would be lower but it seems nice #'s for me !!
