RX8 out Ran My FRS (Rotary Vs Flat 4)
 

After an argument about which car is better, my friend who owns a 2006 Mazda Rx8 VS my FRS.

1/4 Mile Run

On the launch i was a head for like a few second in sport mode using the paddle shifters perfectly, but for some reason i can feel my car maxing out and not moving a fast as i think it would, on each gear high revs and that feeling of getting tossed back in to the seats was missing. i felt oddly out of place.(Felt like i was driving a Hyundai). However, the RX8(also AT W/Paddle Shifters) took the victory by one car length +.

HIGHLY DISAPPOINTING!! :slap:

I dont know if this might be a flaw in my car, or the it has some thing to do with the ECU or Tranny / something else.... any ideas?

Or Rotary Engines Totally Have the upper hand (which i refused to believe):paddle:

The FR-S should eat an automatic RX-8 alive. Now, a manual RX-8 with comparable drivers will beat a manual FR-S/BRZ every single time. Don't know how you lost to that RX-8. Source: I have both cars

IT was an auto FR-S vs a auto RX8, the RX8 has a slightly better power to weight ratio ans more revs per gear.

I am not surprised the RX8 won. Even for a manual vs manual i would expect the RX8 to win (not by much)

What the fuq are you two doing drag racing two slow cars intended for fun in the twisties? LOL

Also, that was a lame Hyundai comment. FYI, the Genesis will smoke you in YOUR game, the 1/4 mile.

I believe he was referring to the Accent, not the Genesis. :thumbsup:

Well the 13b is the bigger motor 1.3x2=2.6l of displacement vs. 2.0. Don't underestimate the rotary :) I think the problem youre actually having is that you're drag racing the frs and expecting it to win...

RX8 out Ran My FRS...

In a straight line it did!


(Remember! You're not in a drag car!)

Few years back I raced my 5spd 99 Miata against an 04 RX-8 auto. I had been driving stick for literally all of two weeks and missed third gear on both my runs.

I still remember how slow it was compared to my FR-S, so like...I dunno, hit them flappy paddles faster?

^13b is not the bigger motor. 1.3 liters is still 1.3 liters lol. And I wasn't aware the automatic FR-S was that much slower than a manual? I know the RX-8 automatic is a lot slower than a manual. It had 7,500RPM and produced significantly lower HP than the 9,000RPM manual.

Are you sure about that? They seem dead-even on paper (both tested by C/D):

RX-8 R3 / FR-S

0-60: 6.3 s / 6.4 s
0-100: 16.9 s / 16.6 s
1/4: 14.9@94 / 14.9@95

Call me a liar or whatever but I took an rx8 I believe it must have been an auto in the 1/8th mile drag in my 03 outback 5spd with just a catback and an intake....

I have a series 1 MT '04 RX-8 which quoted 14.3 at the 1/4th. In this article from caranddriver, 14.5 for MT. " the RX-8 scooted to 60 mph in 5.9 seconds and through the quarter-mile in 14.5 seconds at 96 mph." You are quoting the series II RX-8 R3 which is heavier. Besides, the OP raced an automatic RX-8, which is significantly slower than a MT with only 7,500RPM redline

You're right 654cc per rotor. I stand corrected.:thumbup:

While technically it is still 1.3 Liters, it is generally agreed that 4 stroke reciprocating engines have non power producing strokes, and wankel rotaries both do not have this issue and have other advantages, and because of this somewhere between 1.6 and 2.3x the displacement is required to make an engine of similar power. I don't know the exact figure regarding torque though.

But Yes you are correct, the lower revving automatic will lose out on a good portion of the advantage of this engine before considering the slushbox.

Cool thanks! I didn't realize the RX-8 had gotten slower over the years. I've updated the chart.

2004 RX-8 / 2009 RX-8 R3 / FR-S

0-60: 5.9 s / 6.3 s / 6.4 s
0-100: 15.8 s / 16.9 s / 16.6 s
1/4: 14.5@96 / 14.9@94 / 14.9@95

I guess it really depends which year RX-8 we're talking about.

Glad I could be of help! The OP raced a 2006 RX-8 so I was using series I results

He wins by one car length, you win by 10mpg and no oil consumption. Seems worth it.

P.S. he can't even touch the top 1,500RPM's with his auto box or the torque converter will blow up. The manual goes to 9000 rpm, the auto only 7500. Such a waste!

In the 13b the 1.3L is the displacement for the whole engine. for that engine it is approximately .65L per rotor. the 2.6L is an equivalent displacement but not actual displacement.

:happy0180: The FRS will win this bout, because you're not racing the rx8...you're racing the tow truck, and the rx8...

haha that race isn't about which one is faster it's about which is not as slow :lol:

Let's see how far each car can travel on 10 gallons of fuel.

Let's see which car burns more oil over the course of 3000 miles.

Like a guy who builds and races RX7's and owns a Mazda shop says all the time: "People just don't get that the Rotary engine needs to be treated like it's a 2 cycle engine."

well lets be real here i mean the rx7 does in fact have 30 hp give or take than we do

@OP why didn't you switched cars and did another "honest" race? That will def. clear more things to both.

I saw that parking lot picture and knew I had seen it before! Good old Guam!

I imagine this race going down in my mind. Two racey lookin' cars going full bore... then the old lady in the camry passing both of them. haha.

I've seen continents move faster... full blown continents.

Of course, I'm joking. But the RX8 is pretty slow. Hell, I thought the S2000 was slow and saw that video of one smashing a FRS. But besides knocking on the factory straight line performance, I'm looking at potential. And a BRZ with 350whp screams perfection to me.

A race between a snail and a turtle ;)

maybe full blown continents but how about naturally aspirated continents?

touche.

Full blown seems to make everything pretty quick.:lol:

Whoever said the auto RX8 have a better P2W ratio doesn't know that the automatic version is around 200hp and weigh around 3000+ lbs.

This is like the two weakest kids in school arm wrestling to settle their differences…

What is the point? Drag racing is not a strong attribute of either of these cars… There are literally Mini Vans out there that are faster in a straight line than both of you… Take them to a road course, auto cross event or on some mountain pass roads and then see which is better…

BTW, Usain Bolt is faster in a 1/4 mile…

Peace!

:D

Ba-dap-ching!

Any FRS/BRZ should beat an AUTOMATIC RX8 in the 1/4 mile... period. What happened here was probably driver error/skill differences. Also do you have time slips? Or were you doing this on the street...? (facepalm if so)

Even if it was on the street, not like they could break the speed limit :P

Reminds me of driving my Festiva. Launching the car off the limiter... buuum buuum buuum chirp. Wheel burrow sized 155r12 tires, barely chirping off the 1300cc of fury twisting at the helm. These moments are fury are remembered only by the 3" streaks of rubber they left behind. Sigh, good times.

yeah, i agree. take these cars to the road course. that's the place to really and truly appreciate these specific cars!

btw, oooh, we have a gt-r guy on board. envy! :wub:

lol not gonna lie, do miss their 3 dollar drag races. takes the sting out of racing slow cars.

Had to quote this. Your Username is hilarious. Please post more, because every time I see it, it makes me laugh.

how many miles do you have? it is possible your car is not yet finish break in yet. or maybe you left your park brake on? or you forgot to take out the dead body out of your trunk? or maybe you accidentally put in 87 octane?

Thank you… BTW the BRZ is awesome too… :happy0180:
