13.1?? Might want to check those stats again!

 

correction....13.7!

 

I think GM needs to match the EPA mpg rating more than the hp. I am sure they can do both though.

 

i dunno...i'm very curious to see how gm wrangles this horse with a 200-300 pound disadvantage. from inception i've always felt the gen 5 camaro was far too large...it should never have been any bigger than a 2003 mustang. now they're looking towards alpha in 2015 for weight savings when they had the chance 4 years ago to start this thing out smaller and lighter. most important thing, though, is they must do something to keep the much-ballyhooed sales advantage they've been enjoying over the mustang in the past 12 months.

 

For those interested, the new Mustang V8 will soon arrive on our shores... albeit with a huffer.

Cannot wait to drive it!

 

I read a story about that.

They said the base motor was going to make 422 hp and 405 tq. If that motor is blown either it has to be a good bit different than the american mustang 5.0 or they are only running 1 psi of boost.

But I see the article you linked rates power differently. So the one that I read quoting hp numbers could be wrong.

 

422 is the correct conversion from 315kw. It looks to me as though they're going for more power lower in the rev range rather than more peak power. It could also be that they don't want a higher rating for political reasons....

 

I'm betting it would put out more power than that. Ford are very conservative in the way they quote outputs down here. The 310kW F6 puts out more like 340kW. They are quicker than the HSV LS3s by around 3 mph terminal speed down the quarter but the F6 isn't as quick around an open circuit.

 

Interesting I read this over on a stang site. Could be the 3.73 actually holding this thing back?

 

3.73 gears, 27.5" tire, 1.33 tranny gear (4th) calculates to 113 mph @ 6850 rpm. Given that this is only 250-300 rpm above peak HP, then 3.73s should NOT be artificially lowering the MPH.

4.10s or 4.56s would mandate the use of 5th gear (1:1) in the 1/4 mile. That might be ok, but it depends on whether or not the MT82 transmission can be aggressively shifted into 5th gear (such as is possible on the 2/3 shift).

From a drag racing perspective, I want to be hitting the rev limiter just before the traps.

 

but the mustang has 255-40-19 which is 27" which would put it at 111tops. I think it WOULD be better with the 3.55 or a slightly taller tire so that they can just leave it in gear and finish the quarter in 4th OR go with a much shorter gear like 4.10 or 4.56 and make 5th more usable in the quarter. Although that might make 1st gear almost unusable, or possibly too many shifts, or 5th gear might not be able to be aggressively shifted like you said. Im curious as to how all that will play out.

 

that is a definate possibility. I think leaving the 3.73's and bumping up the redline would definately be an option. Id still consider that "stock" when those numbers come out as well since all thats changed is the shift point.

 

If they shifted into 5th, then I could see it hurting the MPH. Otherwise, unless they are actually hitting the rev limiter, I just don't see it.

Could be wrong though.

 

I didn't want to open up a new thread as it's conjecture at this point... so I thought I might add the rumor to this thread regarding GM's 2011 LS3 power upgrade.

The HSV LS3 is rumored to get some LS7 performance parts (i.e.cam etc...) to tide the engine over until the GenV powerplant arrives.

Here.

 

thats crazy! but im sure theyd debut it first in the corvette though. I think we should look at the corvette to see whats going on with their engines
