Could the new LLT 3.6L DI be considered this generations "Mouse Motor"????

Looking at the specs of the new 3.6L DI motor I noticed it's specific output per Cubic Inch is 1.4. That's more than the LS3 and more than the mightly LS7.

At 1.4 HP per CI, the new 3.6L DI is a pretty impressive powerplant. It should this generations "Mouse Motor".

The SBC was nicknamed "mouse" not because it was a V8, but because it was small compared to other V8 engines of the time, right? Now it's GM's only V8...something could step up and take the place of the "mouse motor"...



Good question, imo......I dunno. It would be cool to have some sort of nickname for such a potent little power plant.

I wonder if the next V8 will be just two more cylinders added to this one. If it was the same displacement per cylinder as now it would be 400hp 4.7L V8. Now bump that up to 6.2L.

Interesting comparison. The ZO6 has a 427...small block. It'll be interesting just how much more power they get out of the 3.6

The next V8s will be a new generation of GM motors. They will be different—more efficient, more powerful, better designed.

It won't. They will be 90 degree V, cam in block designs and will feature direct injection, active fuel management, and variable valve timing.

add e85 and a turbo and we'll be looking at some stupid crazy power and mpg numbers

Back in the day, big block Chevy engines were Rat motors, the SBC was a Mouse motor.

On a related note, the LLT block is designed to support up to 4.0 liters of displacement. Been thinking about this a lot lately - was thinking of just doing bolt ons (a custom spectre modular intake with a crap load of flow, a custom header back exhaust, porting the throttle body/intake manifold, etc) until its no longer my daily driver - or at least no longer under warranty - and then boring the block to 4.0, dropping in new lower CR pistons, and turbocharging the thing. After some weight reduction mods and a full suspension, the thing would be a track beast.
- Xanthos

P.S. - The other idea I was kicking around would be to bore the block to 4.0, drop in pistons designed to maintain the 11.3:1 compression ratio, and then cam it. Once again, it would probably have some impressive power.

It's definitely the new six cylinder tuner king. Once the D/I coding is cracked the possibilities are immense.

That's exciting, but besides D3 has anyone actually proven that DI is better for tuning than FI?

What I would be excited about is the turbo possibility of this engine. With the DI, you wouldn't have to lower compression too much if at all (look at the 4 cyl and 6 cyl mazda and bmw engines that are DI and turbo making good power). I would say you could be looking at a 400hp engine w/ a very nice torque curve ..

Or the Cobalt SS. It has a DI turbo.

Interesting, so essentially you can have high CR AND still retain moderate boost. I wonder what a car at that weight with 400whp and a nice high stall converter would do in a 1/4 mile???

Let me put it to you this way. Diesels are Direct Injection, and how much power do you get out of those with just a simple hand tuner? About 100hp on average, and even more torque. Turbo diesel motors still have that insane compression (13:1 and more) and handle high boost like a champ. Now imagine all of these things in a gas motor that can spin even higher RPM. That gives you a vague idea of what we're dealing with here.

Thanks, I didn't realize this was the systemused in the diesels.

They already have two prototypes running (that I'm aware of via reading news articles, etc) based off of the Ecotec-family.
