remember, you can run a higher afr on direct injection engines. different ball game here. the injectors should be good to what the stock engine can handle boosted.

Hahah yeah we're seeing the same one. Sorry, wasn't too clear. I was commenting on how incredibly flat that torque curve is. Because of this, I think that GM's next V-8 that they develop should be a Direct Injected VVT DOHC motor so we can get awesome mileage, great power, and ridiculous torque curves like the one put up by the V-6.

So the AFR should be lower than 11.4?

Can the ECU be tuned or does it need to be replaced to get more performance? Hopefully someone makes a program for that soon =)

It should be higher than 11.4. That's very, very rich (lots of fuel, not enough air). 12.5 is about where you want it on a naturally aspirated motor for the best power. 14.7 is the "perfect" ratio, or stoiciometric ratio, where you have 14.7 parts air to 1 part fuel by weight and it creates a complete combustion.

And the ECU can be tuned (hopefully) to adjust this and many other parameters.

Ahh thanks Bud. I'm a tuner-tard

So a CAI should bump it up to 12.5+?

Atleast these numbers aren't to far off from a New Mustang Gt...

I cannot wait until someone rips a 12.x with the V6.

With nothing but bolt on's.

With stock tires.

10-11 second twin turbo cars in the future?

Guys were rippin' 9's with the Grand Nationals. Those V6's are nothing compared to this new engine.

how about weight? im guessing the GN is quite a bit lighter? or am i wrong? And what can we expect with a tune and CAI?

G-bodies are also solid axles with a thousand pound weight difference.

But you are right, the 3800 is an old, old design.

No, the computer right now is basically telling it for X amount of air entering the engine, inject Y amount of fuel to create a certain A:F ratio. The O2 sensor lets it know where the mixture is.

The thing about it is that at WOT (Wide Open Throttle) the engine goes into what is known as Open Loop mode. This is because the O2 sensors that come on cars are really only accurate close to the 14.7:1 ratio. As it gets further away from that number, it becomes exponentially more inaccurate. This is why a good tuner uses a wide-band O2 sensor. Anyway,when this happens, the ECU stops taking readings from the O2 sensor and basically injects a pre-determined amount of fuel. Engineers from the factory tend to play it safe and tell it to inject more than what is needed. You don't want to run lean at WOT. It would take more than a CAI to cause it to run 12.5:1. A tune is definitely in order.

The V6 in the Camaro is a very impressive motor. It looks like it will be a hell of a platform to mod.
