Question about LS3 engine - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

mpate16 · 01-15-2011, 03:27 PM

Why is it the Manual SS engine is 426 Hp and the corvette is 430? I know it's not a big diff but if they are the same engine , why less for camaro

Different airflow. Just like the V6 camaro having more HP than the cadillac even though its the same engine.

Nah, so close it must be a marketing thing. The corvette had to be better. Notice how torque and hp peak at exact same place. The engines are almost identical.

SS
Torque: 420 ft-lbs. @ 4600 rpm
Horsepower: 426 hp @ 5900 rpm

Corvette
Torque: 424 ft-lbs. @ 4600 rpm
Horsepower: 430 hp @ 5900 rpm

Exhaust system differences and Corvette marketing.

It has very little to do with Corvette marketing. But rather Corvette engineering.

The people on the Corvette team did an amazing job at optimizing airflow for the car. And so it's slightly more efficient than the Camaro (because that team did a great job, too.

)

It's nice to think that 4 hp/tq is the amount that would make a difference in marketing...but this time...it's all about airflow.

I think its airflow from the marketers' mouths. Vette sales have been slipping last few years.

well i was just curious.... do you guys think a auto 2011 ss camaro could take a 2008 base vette?

leviticus88 · 01-15-2011, 07:32 PM

I'd be willing to bet they have a different engine tune aswell.

Either way, the Hp is what ever GM says it is.
Then you take the car to a dyno and learn the truth (Whp).

How? The Camaro is a pig compared to the Vette, and has a higher drag coefficient.

Vette costs a lot more though

No i don't. The Vette is about 1,000lbs lighter. Won't even be close.

mpate16 · 01-15-2011, 07:42 PM

oh ok... my neighbor has a 08 vette, was just wondering if it would be close

lol marketing......

It's the exhaust. We've been over this numerous times.

LimaCharlie · 01-15-2011, 09:23 PM

Regardless of exhaust flow, intake design, etc., GM will NEVER advertise the Camaro with more horsepower than the Corvette. With that said, nothing in the GM lineup will ever have more horsepower than the ZR1 Corvette.
