I've said before, but the new trucks are rumored to be getting skip fire DOD and there have been slight rumors of a LT-2. It's not a given, but it's possible. As said, the 5th gen is the only Camaro that didn't get power bumps.

It won't need a power bump to stay ahead, but who doesn't like more power???

Maybe all GM needs to do is add the port injection to the LT1 direct injection like they did on the LT5 . A few other tweaks and we could have a 475 hp LT1.

That said, that would probably be enough to keep it the "magazine tests" faster car above the Mustang. Heck, I think the current car still has the edge, but that 10 speed is a big deal for the Mustang. Its neck and neck.

I agree, the Camaro needs the 10 speed and a little more gear. Ford uses a 3.55 gear with the 10 speed auto which has identical gear ratio's as the 10 speed ZL1 , the ZL1 uses a 2.77 rear and the 8 speed Camaro uses the same 2.77 gear.

The SS 1LE has Super Car 3 tires. Not quite like the Cup 2’s, but they are way, way better than the run flats on the SS, and will last five times longer than Cup 2’s.

They gear these cars to compliment the characteristics of the engine and to accomplish whatever goals they have for the car. DOHC V8 engines make no torque or hp in the lower RPMs but the engine can rev to 7500. So they use a numerically higher gear to help out. And the extra 2 trans gears help out so it doesn't kill the top speed of the car. OHV engines make tons of low end hp/tq. So they can get away with a numerically lower gear ratio which will also help it not lose top end...since OHV engines don't rev as high and can sometimes start to tire out up top. Plus there are track duty concerns they took into consideration when they designed the car. A numerically higher ratio would likely have an ill-effect on the car's overall performance. The Mustang will not be as well rounded as the SS and will only be able to do straight line runs so the gears are gonna help it get up and go.

I think the A8 is just fine for the SS. Adding the A10 will just increase cost and make take away from it if you ask me.

Honestly I would not want to deal with a any more gear changes....8 is already borderline.

The SS needs the A10... trust me on that one. Especially tuned like it is in the ZL1.

Lund just put 462/431 tuned on E85 with JLT intake. Thats FBO with manifold 15-17. Pretty nice.

[ULTRAZLS1]

What was baseline?

On happy dyno FBO 15-17 seen close to 500 rwhp. Seen several 480+. Cobra jet with larger TB will get highest numbers

[Speedofsound]

I want to say Lunds baseline was 430/400. Usually boss manifold/ shelby manifold setups are in the 460ish range. CJ and single blade a bit higher.

Usually yeah...but ive seen guys claim near 500rwhp

So they gain big like the Camaro. 30-40 rwhp.

But also Lund said they didn't get a ton on 93. Like the Camaro.

Must be the new DI allows aggressive tuning from the factory.

Peak power #s the 5.0 will have the advantage over the LT1. I hope Chevy implements PI on future LT1s.
Is there any aftermarket intake manifolds with PI?

I thought Mustang guys didn't believe in CAIs. They say it doesn't do anything. I'm guessing now it does??

I have never seen any of them close to 500. Or, the closest to 500 I have seen with FBO is about 460.

If I know anything about JLTs on the S550 is that they LOVE heat. I mean, they get extremely hot. All the open intake systems do. I had an Airaid on mine with the insert cut out. I then switched to JLT just because I liked the looks. My temps got soo hot I got rid of it. On relatively cool days my temps would hit 130s, 140s after about 20 min driving. So while this dyno may look good because they gave the car plenty of cool down time and probably dynoed it with the hood open, I'm betting it'll start pulling timing, losing hp, and will be slower after a few minutes of driving with the hood closed.

They'll hit 500 on ftw purple

Some guys dont, some guys do. JLT and Pmas are the popular ones, there are sheets showing ok gains, but yes, it doesnt help any car to let it idle and heat soak with an open element filter before a race.
