What engine do we have in the 1le

lets let that one simmer.

Rotating weight is more important than static weight.

Supposedly if you remove 1 pound of rotating weight (wheels), it's equal to removing 3 pounds of non-rotating weight (frame).

Can an Engineer confirm this?

Crystal, I'm an Electrical Engineer. An ME or CE could explain it better.

Think about a wheel that you drag on an imaginary friction-less surface (just to make it simple) without rotating it - just linear motion. Now you add rotation to it on top of the linear motion just the like the real life case. You'd certainly have to 'work' harder to account for the extra rotational kinetic energy in the second case meaning you need more HP. Rotational inertia of the rotating object acts like an 'extra mass'. So working backwards, taking off rotational mass would always give you better gain than taking off the same amount of linear/static mass. The exact amount of savings actually depends on the radius and few other things. Hope it makes sense

Wrong

Hearing that and it makes me laugh... The only difference is the rear end ratio and the tire height... It's the lack of a power steering pump that makes them dyno higher, that being said the regular 2013 ss's dyno the same..

Ryne. Are you sure about the only diff being the change from hydraulic to EPS? I can guarantee you will not see the gains the 13s have seen with just that change.

If you want proof find a belt that allows you to eliminate the power steering on the 2010-2012 LS3 motors or a pulley to bypass it and Dyno the car with and without the PS pump drag.

I have tuned 20+ 2013 cars, both 1le and ss's. the tunes are identical other the. Aforementioned differences earlier.. And yes the 2013 ss's dyno roughly the same.... Can you provide any proof of the "hot" tune?? Because I have proof that it is not....

[krazzyk01]

I have to ask this question. I bought a dealer stock 1LE and I've never heard of NPP exhaust. I know what the dual mode is. I've been under my car only once so far and looking at the system I have I noticed there is a cross over pipe and it looks to be a decent diameter. I can hear the backfiring during downshifting and it's 100% louder than the last 2013 Camaro I had which was a 2SS with the "stock" system on it. That system is way too far quiet for a sports car.

Thanks,

I never said anything about a different tune. I was responding to this commenter below.

You infer that the only reason the 13s Dyno higher is because of the change from hydraulic to electric power steering removing the parasitic loss of the serp belt turning the pump. Yes, my career in the past had me working with EPS systems in vehicles and I am very aware of the power they "free up" from a motor and it does not explain the delta between the 2010-2012 and what the 2013s are producing at the rear wheels on the Dyno.

Edit: Ryne, I am by no means a Camaro expert. But I have been told the 2013s are dynoing 20+whp higher than previous 2010-2012 LS3/M6 models which is what my comments are based on. Can you confirm this is true and if not what whp difference are you seeing from 10-12 to 13?

FYI. There is some speculation in this thread, some wrong info, some silly sarcastic info and then some info from people that know more than they are allowed to share I love this place.

What's a kayak, canoe and a boat that's lost it's motor have in common?

My last 3400lb 4cyl turbo street car ran 11.33 @ 122mph. It was AWD and ran 1.5/1.6 60fts on all season street tires . Don't doubt the Turbo!

From my experience on our dyno they are only baselining roughly 10 hp more, in fact my 1le baselined 372 rwhp which is right in line with most of the 10-12 ss's

That is interesting. All of the talk online had me believing they were putting out 20+ whp more than the 10-12MY.

yeah, but they gave you a slow one knowing you'd mod the hell out it anyway!

Yea but that is only if you have the 1.21 Gigawatts or some stolen Plutonium.
