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

I agree. I know it's not a direct comparison because of lack of AFM, but the v6's have had VVT and DI for years now and back before they went to the new design without exhaust manifolds, you could get good power from the v6 with just headers, CAI, tune. I'd imagine it wouldn't be that different from the LS3 in that aspect... Depends too on how restrictive their cat-system is on the LT1.

Agreed. The biggest difference is going to be how AFM plays along.

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

With a 0-60 like we have heard about and a time I'm sure will be improved upon is exciting. It's going to scream off the showroom floor:sad:

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.

BSR-1 01-24-2013 10:21 AM

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.

x2!

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

You can't just simply turn off AFM on L99 Camaros... w/o an aftermarket tune and thus voiding your warranty.
We'll see on the new :stingray:

Yes it does... sounds like a Honda/Toyota, etc.. on my stock (untuned) L99, I got rid of my Flowmaster AT due to that fact alone... annoyed me like a dingbat at 75-80mph.... like a severely out-of-tune tuba. :mad0259:

ssmike 01-30-2013 08:29 PM

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

Strangely similar to a ls7?

Now imagine a bigger block with di and holy hell what a beast.

This entire line up is going to be sick. :chevy:

Haven't driven one.
I hadn't thought of the "sound" drawback that others mentioned. I suppose that could be annoying.

imported_bolteon593 01-30-2013 09:20 PM

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.

They addressed that issue with this particular car involving the exhaust tone while afm is active.

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.

ec1990 01-30-2013 09:33 PM

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.

That's what I thought when I bought my Camaro SS. It didn't take too long though before the mod bug overtook the fear of loosing my warranty! Just have to be prepared to pony up the cash if something breaks!

AFM and skip shift are the 2 most ANNOYING features of these cars! All in the name of making the EPA happy! What a bunch of crap! :mad0259:

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

Are you referring to a factory sc di engine with afm?

firecross91 02-02-2013 09:57 AM

Either/or. Heard somewhere that the valves in the AFM may not be up to high compression.

FenwickHockey65 02-02-2013 10:01 AM

Let's just say the Gen Vs were designed with forced induction in mind.

I can see this motor squeezing out 475rwhp with heders, exhaust, intake and tune.

So pay 3k+ for 25hp awesome. Esier said than done. Anyone that does the dyno homework knows these cars will be pretty close of the showroom floor. No exhaust system (sans headers) has proven to make power. The stock stuff is usually heavy so the weight saving makes the car quicker but no so much the power gain.

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...

Supercharging does not per-say stress out the exhaust valves like turbos do based on cylinder pressure. I am sure 6 psi on this motor will be forth a good 130hp to the rear whhels:)

figure 550rwhp
