New Cars, better engines!??

[hasenbonkers]

Ok, for instance, tht STUPID 350Z!! How the hell did they get 300HP out of a 3.5 liter while chevy gets 305 out of a 5.7liter! And our 3.8 liters barely push 200?? It bugs me, ha. Seems like all the new engines are just better technology, discuss

I like the 350Z... sexy car man. How is it stupid?

Re: New Cars, better engines!??

the same way a 3800 is reated 200 hp /225 torque, and an LG4 (v8 peeps) is rated 170 hp/250 tq. Technology. ALso the same way those 3.9/3.5 v6's are putting out some good numbers.

Re: New Cars, better engines!??

Its just engine design and technology.


Now whats responds to mods better a 350Z or a Ls1?


Very easily.

Re: New Cars, better engines!??

you also have to remember that the 3.8 you are running was designed at the latest 94 and slightly tweeked along the way. thats freaking old. Ls1's are old motors too. you can't compare old to new

When chevy was getting 305 out of a 5.7L it was 1992.

Re: New Cars, better engines!??

ls1s made 350hp.. but..

that's nissans fastest car, its rated at 275-285 BTW, plus it has dual overhead cams, it revs really high, thus making alot of power.

Re: New Cars, better engines!??

you're not taking torque into account. Comparing two motors, one bigger, one much smaller with the same hp rating, chances are the bigger motor will have a LOT more torque. Also, the LS1 is underrated at 305 (in LS1 Z28s). Look at the four-cylinder in the S2000...little motor pushing 240 hp, but it doesn't respond well to mods because it's been milked for almost all it's worth at the factory.


EDIT: As an example, take the 2006 350Z: 300 hp and 260 lbs. ft. The LS1 makes 305 hp (at least, probably more in the range of 350) and is rated at 350 lbs ft. That's a difference of 90 lbs ft. That's a lot of torque!!!

The VQ35DE has an aluminum engine block and aluminum DOHC cylinder heads. It uses SFI fuel injection, has 4 valves per cylinder with VVT, optimizes opening of intake valves and features forged steel connecting rods, a microfinished one-piece cast camshaft, and Nissan's nylon intake manifold technology. It has low-friction molybdenum-coated pistons. The intake System is a high-flow tuned induction system.

^^ from wikipedia. i'm sure the rabbit hole goes deeper, but we all know that an engine has to be balanced, and with the newer technology, its easier to find that with computer modeling. they are getting to the point where they dont necessarily have to do crash tests anymore cuz the modeling is so accurate. the only thing i dont understand is why GM likes pushrods so much... even the LS7 is a pushrod if i'm not mistaken..

Re: New Cars, better engines!??

the new Impalas are like 3.4liter but make 250hp

[BLLDOGG]

Re: New Cars, better engines!??

new impalas come with the 3.5, 3.9 or 5.3

Re: New Cars, better engines!??

The LS6 made 405 hp out of 346 cubes. Thats not bad.

It's really about torque under the curve. The LS1 has a much flatter TQ curve than the VQ engine. Who cares about peak numbers anyways. What good is peak TQ when you only have it for 500rpms?

Re: New Cars, better engines!??

i thought 350z had turbos? guess not

[Fbody3400]

Re: New Cars, better engines!??

No, 350Zs don't have turbos, but TT 350Z still don't make the power they should for being twin turbo'd
