RX-8 vs RX-7

[Carl]

I know of two people who tested the acceleration of a standard RX7 3rd gen and an RX8 and up to 140mph the RX8 was still with the RX7!After that point the RX7 pulled away.It is likely on a track that an RX7 would not get above 140mph unless there is a very long straight,which most circuits don\'t have.
I also will back up Clives comment that the around Laguna Seca the RX8 did match the time of the RX7.It maybe that the track was better suited to the rX8 but no 2 tracks are the same.If you tried this exercise on a different track you would get different results.
Kind regards

I gave one a good spanking on the A3 from around 90 mph top 130 but admittedly I was not in a complete stock 7 and yes the 8 driver was trying. I think I will go for a test drive in one soon to see what they are really like for myself.
There\'s absolutely loads of them about which is good for the rotary seen in the UK.

I think that many people who are driving these cars are not of the rotary mind set.I think some are afraid to rev them when they have been run in.
If you keep one in the 7000 to 9000 rpm range you will see that it is a quick car and can get you into high speeds very quickly,it is not so in your face as a 7 because of the 7 having 90% of its torque low down at 2000 rpm.
So get the RX8 singing and you will see.
Kind regards

Sorry Clive, but this was Mazda propaganda.

Watch Best Motoring International #8 - the drivers have nothing to prove.  On teh track the RX-7 is comfortably quicker than teh RX-8.  On the Togue run (down hill street racing), the RX-7 was faster, BUT the RX-8 was far closer than they expected - all (in both tests) due to the softer suspencion setup on teh RX-8 and the fact they felt the RX-7 was too stiff for the bumps and dips of a road surface.

where can i get that best motoring international #8, is it available to download anywhere??

Thanks

As by coincidence, hopefulyl tonight a friend will be dropping off a DVD ripping application with me.  As BMI is not avaiable in the UK I will see if I can cut various sections of it and try and find some one to host those vids for me.

It should eb noted that the drivers do like the car, unlike the Z350 which Gansan describes as unfinished.

Totally agree, although I don\'t think it\'s limited to rotary. I found driving the rotary was like driving any NA car with a narrow power band (if I may use such an old-fashioned term) - reminded me of a go in me mate\'s rally car (205 1.9GTi - although add 3000 revs for the Mazda :cool )

In fact that put me off the 350... such a wide torque curve it may as well be a turbo.

The problem is 90% of people don\'t understand torque, power, and gearing, and if you just don\'t get it you won\'t get the best out of an 8. I\'ve ordered my 8 specifically BECAUSE it\'s a total go-kart with short gearing and six ratios! Much more fun to drive than anything else I looked at.

(It\'s similar over in the 300ZX world... "I bought an NA and it\'s slow" or "I bought a 350Z and it\'s slow" and it usually turns out they\'re changing up at 5000 revs.)

I\'d also agree with comments I\'ve seen here... lots of RX8 owners don\'t understand the history and they\'ve bought it as a new car instead of their 3-series or A4 or what have you. I think they\'ll be fed up when they realise they have no torque and low economy, and we might see a few nearly-news around next year in Autotrader.

I hope you can get the Rx8 vs Spirit R contests hosted

well the 7 in stock form is particularly powerfull over the 8 is it? Though i was under the impression the 8 was a lot heavier and this would slow it down, they\'re faster than i realised.

also isn\'t the 7 a lot easier to get more power from modification-wise??

I hope you\'re not waiting for a reply - this thread is four years old. :eek

[dthebuk]

lol oops.... though id give it a read

now i feel a bit silly :Hammer

Don\'t worry - it was only because zevans hasn\'t been around for ages that I realised.

single turbo fd rx7 all the way mate...

[BlitzBoy]

to add to this old thread, in terms of accelaration, I healthy stock RX7 will do mid 13 second quarters where a rx8 will do late 14s early 15s.
But the rx8 is a stiffer car, but is heavier then the 7, so handling is on par, I think if Mazda made a lightweight rx8 around 1200kg then it would outhandle the 7 and outperform on the track

My mum has a 250ps rx8 (import) running on superplus, so probably 240\'ish bhp in the uk cos of are crap fuel and I had a stock RX7 with a better IC running around 260\'ish first of all. The 7 out handled and out accelorated the 8 everytime - The 8 is dead from 0-5000 rpm where as the 7 has poke from 2500 - My thoughts are the power band in the RX8 doesnt stay long enough.
 
When my RX7 was mapped by carl (HR) pushing 280+rwhp I was side by side with my mates rx8 230 and I was leaving him standing everything time - both was doing 60mph ready to launch and by the time he got to 100 i was dont over 120mph and that is a big difference to me!!

It\'s unfortunate that a lot of RX-8 owners don\'t wave, but then that\'s the price of car selling success, as in the MX-5. I\'m sure their club members hate the fact that loads of people in MX-5s don\'t wave ! I prefer to let people wave at ME !! Or crank their necks so far round their heads following me. hehe

Stock the RX-7 will do the 8, I hear all of the aboves but there are two types of RX-7, the one driven fairly aggressively, and the balls-out "I\'m racing someone" type of driving. An extra 5% concentration makes the 7 so much faster, I\'ve killed DB-7s before cos they got whooped so quick they gave up. And in the second type of driving, with all that torque and roads the way they are, the superior power and weight will leave the 8 behind. Look at an elise, a fantastically handling car. Lighter than a rex, not sure about bhp per ton but even modified ones get killed by an RX-7.

And yes, I\'ve always been opinionated !! lol

And yes I own my own test track. :p (others call it the Nordschleife.... hehe).
