Has anyone seen the latest issue of GMHTP magazine? They dyno'd a bone stock Corvette GS with the LS3 and 6 speed manual and it put down 415 rwhp. Not bad for a motor rated at 436 hp at the flywheel. I mention this because the LS3's in the manual Vette GS are hand built in the same plant as the LS9 and LS7 and also equipped with a dry sump oil system. At the time of release GM mentioned these motors have a little more hp (wink, wink) than the regular LS3 but most scoffed because they never recertified the motor. I have to believe they will do the same for the 1LE and keep it rated at the regular hp. My 02.

Not dissing the GS LS3s but are they that more powerful? Maybe I need to find more GS times. Probably the owners are not all that interested in the drags.

I think you've hit on many points. The percentage of GS C6s running down the 1/4 mile is very small compared to the "normal" LS3s. Also, I'm not sure if its really 40-45 hp. So far the LS3 M6 Camaros (bolt ons) that have run 11s bolt ons are running drag wheels and tires including skinnies up front. Drag wheels and tires with skinnies up front will shave some serious time off a 1/4 mile. Also, we have a few members (bolt ons) that remove their seats and everything else they can think of to save weight. I'm not sure if that should be allowed, but so far we've allowed it. But that does make it hard for people who don't want to tear up their cars to compete (at the bolt ons level). Eventually someone will completely gut their car (drop 500 lbs) and run high 10s - low 11s (bolt ons) and a new category will need to be made. |

But looking at it another way you can figure there is a 15% driveline loss on an M6 car. So 415 is 85% of 488. 488-430=58 additional crank HP. Seems like a lot even for a full blueprint. I also wondered what "hand assembled" means. Do they get to pick parts closest to engineering spec? Or just carefully build the engine. I like the idea of a person assembling my motor, but how does that add HP?

"Hand-built" engines are exactly that. From premium parts, an entire engine is assembled by ONE person, not on an assembly line like a "conventional LS3, for example. Here's some data from Wixom:
.................................................. .................................................. ........................ Performance Build Center in Wixom (Revised:2012-02-27) Location: 30240 Oak Creek Drive Wixom, Michigan. 48393-2430 United States Year Opened: 2004 Facility Size: 100,000 sq. ft. -------------------------------------------------------------------------------- Employee Information Hourly: 16 Salaried: 6 Total: 22 Union Local: UAW Local 653 Facility Details The plant began building engines in 2005 for the 2006 model year. The products at that time were the 7.0L LS7 for the Corvette Z06 and the 4.4L Supercharged Northstar (LC3) for the STSV and XLRV. The LS7 launched with 505 horsepower and the LC3 with 469 horsepower in the STSV and 443 horsepower in the XLRV. The LC3 was discontinued after the 2009 model year due to market conditions. The PBC currently builds the 6.2L LS3 V8 for the Grand Sport Coupe manual version, the 7.0L LS7 V8 for the Z06 and the 6.2L Supercharged LS9 for the Corvette ZR1. GM Powertrain Wixom Performance Build Center employs 22 people. Hourly employees are represented by UAW Local 653. The plant produces high performance engines for specialized, high-image powertrains for General Motors' premier vehicles. 3,376 engines were produced in the 2011 calendar year. Investments 2004 - $10 million to produce hand-built high-performance engines Products & 2011 CY Volume: ■6.2L V8 Grand Sport Engine LS3Dry Sump (2011 CY produced: 1,841) ■7.0L V8 ZO6 Engine LS7 (2011 CY produced: 1,099) ■6.2L V8 Supercharged Engine LS9 (2011 CY produced 436) Product Applications: Chevrolet Corvette .................................................. .................................................. ........................ With CY 2011 production of less than 1100 LS7s, and 3376 TOTAL, this facility has built as many as 10,000 engines in a Year. Could an LS7, destined for a ZEE, keep this facility going, post-C6? Would it be possible to sell 5,000+ ZEEs per year in MY '14-'15? . Last edited by LOWDOWN; 04-10-2012 at 01:12 PM. |

If the electric steering is worth 5 hp and the exhaust flappers are worth 6 hp are we going to see 437hp sae net?

I am almost positive I heard the Boss in underrated. I remember everyone talking about quarter miles times and nobody cared about what happens in autocross until they saw the 670 HP GT500. Which is most likely going to beat the ZL1 in a 1/4

I'll agree with you on this.
boss does a good job around the track. but like the ZL1 I have a feeling the the 1LE will be easier to drive around the track. |
