Whats the boost in torque from on the LS7?
I noticed the Z/28 has more torque then the Z06 with the same engine.Does anyone know what changes were made?

Sellin Chevy's since '06

It's gonna be a HP bump too but Chevy is under-rating it. Open element K&N intake, tri-y shorty manifolds and electric power steering. From my '12-'13 Camaro LS3 cars the electric power steering variable showed up as 20 HP on a dyno. All my power mods were swapped at trade-in and 2nd dyno was in warmer weather. Chevrolet is down playing it by rating it at only 11 more TQ.

I'd say it is mostly in the tri y exhaust and the rest of the exhaust system.

Better flowing exhaust is probably the biggest change.

Pankl titanium connecting rods were added, as well as Mahle pistons, and a revised air intake with K&N cold-air induction and exhaust headers. http://www.autoblog.com/2013/10/16/2...-review-video/ Best regards, Elie

interesting, so is compression ratio the same? Remember they said at least 505bhp, I think its closer to 550bhp but I'm still surprised it couldn't go past 161mph it seemed to be stuck there on the straight.

Yes I believe the CR is the same. I'm surprised as well at the 505 HP while the Torque has been increased. I'm with you on the HP it is probably closer to 525. The run on the straight obviously was held back due to the wet surface.

I don't think it had anything to do with the wet surface, the car wouldn't have "slipped" out of control in that gear, however I think the HP boost is larger than you think it is, check out the tri-y tubular short tube "headers", cold air intake and electrical power steering and possibly some other shit we don't know about, the tune might be more aggressive who knows?

Intake = 6 HP ? Exhaust = 9 HP ? Electric Steering = 5 HP ?
