The 997 will be longer, taller and wider than the current model, and the range could even feature an eight-cylinder engine: the engine bay is said to be large enough to accommodate one, thanks to the widened rear track. The 450bhp, 4.5-litre bi-turbo unit used in the Cayenne would be an obvious choice of engine to fit, but rumours suggest that Porsche is working on a 5.0-litre flat-eight, which produces 450bhp even in normally-aspirated form. This version could well be badged 'S', to distinguish it from the six-cylinder model, which will probably use the current 3.6-litre, 315bhp engine, enlarged to 3.8 litres to deliver 350bhp, an upgrade which could appear in the last of the 996-series coupes. The standard-fit transmission will be an all-new sequential manual set-up.

5 liter porsche flat 8

 

I love 911 turbo soooo much that i cried when i saw my nighbor buy one and my best friend got one in cash in 2001, red. I love the car to the bone you can drive it every day and with small chip from APR for $2500 you gain 100 whp can you beleive this ****. I am going to buy one in the next few years so i guess i will wait for the 997 then.

 

Damn, we'll have to put more mods on

 

Rolin in my 5.0

 

I guess if they crampped that 5.0 engine in the 911, the tail of the car will be heavy as hell

 

Who cares... it's the bling factor.
When did you see someone in a Porsche drive fast anyways

 

There's so much wrong with that, it's not even funny.

- The 4.5L V8 is just that, a V8. It's longer, taller, and narrower than the 3.6L flat 6. The back (from the firewall to the rear bumper) would have to be substantially (6-8") longer, you'd lose the lower CG of an HO6, and the back would have to be higher.
- In current Cayenne trim, it puts out 340 HP/310 lb-ft. The base 3.6 puts out 320 HP/273 lb-ft. Figure 330/280 out of the 3.8 flat 6. The power gains aren't that good.
- A 5.0L HO8 has the same length problem as the Cayenne motor does.
- Porsche has variants producing well over 400 HP out of the current HO6. The 911 has had an HO6 for as long as it has existed. Tradition is a big deal for 911 owners. There'd be considerable expense. No real reason to switch, is there?

 

An NA flat 8 couldnt weight that much more than a flat 6 with two turbos an intercooler and the extra plumbing it takes to make it all work

 

Good point Brandon. As a base motor, though, there is a weight penalty. If it replaces the TT motor, it'd be a wash (probably lighter).

 

why dont they just build a scaled down version of the GT? how about a GT engined Boxser?

 

Ooh, she's kinda pretty.......
