RX8 vs 350Z on Fifth Gear

[marcusd666]

What\'s nice about the RX8 is that rev it over 6,000rpm you hear feel the engine change it turns it a different car not many 23k cars have a rev counter that goes upto 10,000rpm

Can you rev them still that high with a supercharger fitted I wonder

What I like about the Rx8 is that you can bang it off the limiter for a day without hassle and then potter home at 70mph on the motorway without a problem.  There aren\'t many cars that you can do that with.  I\'m half convinced that revving it is better for it, prevents the carbon build up that can stick down seals and stuff.  A day at the track certainly does things like stop the third port sticking at high revs and generally makes the car feel livelier.  The management system is adaptive and adjusts to track driving giving sharper throttle response and better mid-range.  It messes with your front tyres though but small price to pay!

Sorry to DP but California Style\'s S/C RX8 has no trouble running at 9000rpm.  The supercharger\'s boost is bled away through a bleed valve system that allows a max of 8psi.  It feels like a normal car with on fast forward, same characteristics just faster and because it doesn\'t have a piggy back but uses a reflash on the Stock PCM (ECU) it doesn\'t encounter problems or throw the car into limp home mode like some of the other conversions.

Interesting thread.   But I just wish the RX-8 had MORE POWER.

My one does now its supercharged! Its awesome!

One of the good things about it, is the supercharger keeps the rotary characteristic of more revs = more power...so no boost and fade like a turbo, just smooth power from zero to limit. The dyno curves are just like stock just a lot higher. (not on my one as I haven\'t dynoed post install)

For what its worth the reflash lowers rev limiter 500 revs (I think) to preserve the engine a little bit, but you get so much more power anyway, who cares.

You could always request a full rev range if you wanted I guess.....

My recipe for instant RX8 success is buy a PZ second hand and add supercharger = awesome! (IMHO)

The 350Z has the slow engine from the v6 renault vel satis, look up the drag race between the older 300zx and the 350z, just shows how slow the 350z is as it was designed in california by an indian from liester. I don\'t know why they took forced induction off the rotarys

. I don\'t know why they took forced induction off the rotarys

think they wanted reliability. Plus i think they had several problems with forced induction but mazda are experimenting now.

at the end of the day, the rx8 is slightly less powerfull than the pre 99 7\'s and it suposedly handles better. Look at the mx5, its hardly fast yet its the best selling sports car in the world.

[m1tch]

Hmm well if they wanted reliability, why did they let it rev to 9k lol

[Will66]

It revs to 9k and is reliable.  Engines going on an RX8 is the exception rather than the norm.

[m1tch]

Thats true the revised rotor and oil delivery systems as well as the intake system means it is partially forced induction

[Will66]

I like the slick noise too.  It\'s not as aggressive as a Bridgeport 13B (awesome noise too) but it has the right amount of edge and smoothness, the pops and bangs on the overrun are cool too.

id love them to do a high powered FD on topgear just to see how it would compare with the exotics...

I reckon they should do a jap event with the like of FD\'s, GTR\'s supra\'s etc, now that\'s be good TV
