G35 doesn't have an angy hornet under the hood. So that's a no.

The Rotary exhaust is actually cooler than the V6 in G35, one reason they don't put a Turbo on the Renesis. Too little exhaust heat for the CAT to work properly.

my car sounds like a 747.......

FIRST TIME ROTA OWNA

Hey and another thing they ain't thought of Brettus is that the gas swirl flow's the opposite way here in New Zealand eh! just like the water in the plug holes

Soravia quick, hit the edit button again while you still have a chance....

Actually wait.....thats good sig material

I forget the numbers, but the Renesis exhaust is still hotter than a conventional piston engine. Its just not as hot as the peripheral exhaust port rotaries (RX7).

Its a matter of taste. I think the VQ35's sound like junk. Coffee grinder comes to mind. I tend to favor a healthy V8.

But hey, you like what you like.

Soravia

Then I read wrong somewhere on the internet about the exhaust.

Lol, obviously, the rotary runs a little hotter so I'm sure the car doesn't take the extra energy to cool the exhaust...

EXHAUST COOLING - #1 WAY TO GAIN HORSEPOWER :-P. Needed for "proper" DEI!

Soravia

Cool exhaust gas has increased weight and makes it harder to push it out the pipe to the back compared to hotter exhaust gas with lighter weight.
Cool Exhaust Gas will have negative effect on power output under WOT conditions because the exhaust flow effiency is reduced.

refugeefrompistons

How can the exhaust gas have a higher weight?? You mean higher density I think. Anyways, back pressure is significant but not as much as in a FI due to detonation. At least I think.

Soravia

Yes, I meant density.
A larger pipe (not just the tip) would reduce this effect.

Completely free, maybe. However, with proper pipes an RX-8 going uphill sounds like a 757 climbing out of SNA on one engine: 110% thrust, target pitch +45 degrees [This will give you an idea, about 22 seconds into the video.]

I love the rotary sound

chetrickerman

what the hell, that is weird. i would imagine the high pitched whine coming from that jet engine

eclipsegsx

lol

i want my rx8 to sound like an STI boxer motor with a loud *** exhaust.... mmmmm

And i want a pony for christmas...........oh wait, i got caught up in the moment

tajabaho1

I wish I heard Axial flow's supercharged rx8........I bet that thing sounds like a jet

Ike

It's like Taj part two... Is there some new requirement that all new members must be supremely annoying and say stupid **** all the time?

chetrickerman

well i bet the SC sounds like a jet, but the car will still sound like a rotary
