Corvette LT1 engine mods and bolt-ons
How much potential is there to squeeze more power from the LT1 with mods and bolt ons?
I love how high tech all the new engines are but with all the fancy direct fuel injection, rev matching and cylinder deactivation it makes me think that the days of slapping on a CAI for a few horses might be over. |
I'm betting long-tube headers and a cold-air intake will do wonders.
Then you just have to worry about check engine lights with the LT's :D |

Should run like a bat out of hell with a full tune and full bolt ons! :nod:

Direct injection is going to be huge but also a very large learning curve for those who haven't been playing with it already. Thats why I jumped on the v6 camaro wagon early. I wanted to learn this technology from gm. The cam phasing is nothing new and we'll see big gains from cam swaps just like we do now. But tuning is going to be huge for this motor. I can see this motor squeezing out 475rwhp with heders, exhaust, intake and tune.

I'm sure that AFM can be turned off with a tune like they do on so many L99's.
I've never figured out why they turn it off though. I mean if you can save gas and then go like a bat outa hell whenever you want to......what's the point of de-activating it? |

Have you driven a car with AFM? Turned on you get 1-2mpg more. I'll sacrifice the 1-2mpg to get rid of the annoyance of cylinder deactivation. Especially if you're running any kind of exhaust system. |

AFM is not an enthusiast-friendly option. Nobody wants their V8 to sound like a Honda. |

We'll see on the new :stingray: Quote:

I can only imagine what this engine would be like with LT's, high flow cats, cai, and a tune!

Now imagine a bigger block with di and holy hell what a beast. This entire line up is going to be sick. :chevy: |

I hadn't thought of the "sound" drawback that others mentioned. I suppose that could be annoying. |
could never understand why people mod cars that have warranties.
once the warranty is out, sure; go crazy... but why mess with it in the mean time when there are so many other options to build/customize cars. each to their own and all that. |
Quote:
The standard exhaust improves airflow by 13 percent — GM says — and uses a pair of butterfly valves to adjust the sound when the cylinder deactivation system is in V4 mode. |
Yep, it has two sets of butterfly valves, one to reduce drone, and one during high-revving which opens up all four exhaust outlets instead of just two.

I wonder how SC the engine will be affected with the AFM or vice versa. :noidea:

Either/or. Heard somewhere that the valves in the AFM may not be up to high compression.
|
Let's just say the Gen Vs were designed with forced induction in mind.

Even laptop tunes on the stock motor are very marginal. Hate to be a spoiler. I know in time we all will be able to squeak out gains but I suspecy it won't be that esy to see "real" gains I Know Granatelli will be Twin turboig their prior to SEMA if at all possible and don't count out Procharger and perhaps STS. Not sure the center exh will allow for muffler turbos but... |
