Hey, I'll admit ... swapping a pulley is damn easy, and considering the power gains from doing so, it's obviously a good option if you want to crank up the factory HP and start making BIG #'s like ~600 + .

Hey, you're probably right . Happy??

I guess my original thought/perspective was if GM is building a ~450 HP - 500 HP car, and not considering extreme future mods by the owner (like they did with 3rd/4th-gens and the 7.5" 10-bolt ).

But since ~450 is getting so, uh, "easy" to hit, and if ~600 HP is the next step, well hey, I guess we move onto bigger and better things?? (s/c)??

Ha ha, you may now laugh and point at me for losing!!

 

Having a different perspective is hardly losing.
I work for a company that does a lot of work with s/c's so I may be biased, but from a cost perspective for that performance they can't be beat from the factory, IMHO.

In a very arrogant way maybe I am satisfied, but from your sarcasm I doubt your opinion has changed. So we are still in the same position we were 2 days ago.
In stead of focusing on you liking displacement and me liking s/c's, maybe we should switch to the common ground of us both liking hp, torque, small block v8's, and camaros.

Have a good one

 

Not many people saying a lot about fuel milage, a supercharger effectively increases displacement when needed and runs leaner when not boosting. I know DOD helps, but you can't change bore or stroke sizes, so some waste will still exsist.
Look at all the S/c 3800's out there, no clutter, not much more weight than an intake...and we've all seen big numbers put down by blown LSx motors!
10 second S/C LSx cars are getting pretty common.
Then there's the sleeper factor...

 

Depending on the blower type, that may be true. But don't forget that a blower uses power to run, so you can't base that on displacment.
I don't know what chevy does, but they get great mileage with the small block (per EPA) considering their displacement.

As for sleeper factor - whether you have displacement or s/c, once you blip the throttle you aren't a sleeper anymore

 

Modern superchargers hardly draw any hp while cruising down the highway. Any car that had either engine wouldn't have a stealth factor to begin with.

 

a traditional sump 427 IMO would be badass in an SS version. high teens city and mid high 20's highway MPG...

Who wants to buy a brand new camaro and have to bore, stroke and resleeve the block just to get to that cubic inch. With the 427 you get complete driveablity and dont have to butcher the car to make it fast.

 

I would like to see SS LS3, SS LS7 just like in the olden day SS350 and a SS396. They should have two different engine options like the 60's.

 

Or you could just change a pulley.

It would be just as easy to add a little laughing gas...

I was also hoping for something that wont be a lead sled. Those S/C cars are friggin HEAVY (Cobra) like 38-3900.

Big cubic inch engine in a muscle car...talk about bringing back the old school! Add that to todays technology..man I hope they put the 427 in..

 

The new GT500 is heavy b/c it has an iron block V8. If GM makes an aluminum V-8 it will be much lighter than the GT500.

 

The main reason for the GT500 being so heavy was that they never designed the car to have 500 hp to begin with. They added something like 300 lbs to the chassis so it would be strong enough to withstand the power that motor makes. It has really nothing to do with the fact its got a blower on it. If GM is doing their homework like they appear to be then we will have a car with more power and less weight than its competitor.

 

Adding nitrous to an engine with almost an 11:1 compression ration isn't gonna be a great option. The 03 and 04 Cobra's are street terrors regardless of weight. The GT500 is too limited to realy be a street terror, I'll probably never see one since most will be sitting in some lawyer or doctors garage for 30 years. The big cubic inch is great but the SC will be making more torque. I'm still gonna take whichever one they offer unless we're getting into Vette money!

 

Actually, when set up correctly, nitrous is the best option in terms of forced induction on a high compression engine. Nitrous cools combustion chamber temperatures which helps prevent the pinging/knocking you can experience with a higher compression engine.

 

And what makes you think having a blower making more boost is better for an engine? Think about how much a blower pumps the compression up. For example: 4.06 bore 3.62 stroke with 9:1 static CR under 15 psi boost will create a running (boosted) CR of 10.69:1 at 60% volumetric efficiency. Youre already getting into race gas at that point. The most I see happening on 93 octane pump gas is 9.5 psi.

Now say a 427 at 10.5-11:1 CR with a 150 shot of nitrous on 93 octane pump gas with proper plugs IMO would make more HP and torque. Nitrous makes good gains in torque especially.

Blowers generate a lot of heat, nitrous (as previously stated) cools the combustion chamber.

If you really think weight doesnt play a major role in how fast a car makes it down the track youre nuts!

Of course this is all theoretical..
