It's nice to see someone post some proof of their accomplishments. I don't think you were being a jerk about it either. Nice run. I'm heading to the track for the first time tomorrow. With the exception of a K&N replacement filter, I'll be running absolutely stock. We'll see what happens.

That's nice, really nice. In fact that gives me a cool concept on the drags...but, in relation to video game physics, this RXtuner will whip until a woweelicious 300kph!!! Fact that, its just another imagination....~sigh~

Lestat

Great run... I ran last week and ran a 14.9 at 92.34 mph but launching at 4,500 rpms. I have the toyo t1r's and they are great. I heated them up and they stick at 20 psi. I havent tried launching any higher yet. Ill give it a shot next week and see how she runs... Talk to you soon and great job!!!!

Anyone care if we keep these post for when you try to sell your car on here? Seriously, dragging a car does more damage than anything. Our car isn't exactly great a straight line so why abuse it?

ATL-6s

^^^ Sounds like another drag racer hater Yes we care. Lots of cars are not great straight line cars but ppl still like to race side by side just for the fun of it. Go bitch somewhere else.

I'm wondering what's the best 60 foot anyone has ever pulled in a n/a RX8 on street tires? The 2.1 in this thread is just borderline respectable for a RWD car IMO. I was pulling consistent 2.1-2.2's in FWD cars with 205/50/15 street tires and my M3 was pulling 1.9's all day long on 245/40/17 street tires as well, I'd imagine the RX8 is capable of the same especially with the ability to run up to a 275 rear which would make it a 14.1-14.2 1/4 mile car.

The biggest problem your going to have trying to get an exceptionally low 60ft out of an Rx-8 is controlling the wheelhop off the line, I think the lowest I've heard of was ITO doing a 1.9 a long while ago. There is room for improvement just, at the cost of some drivetrain components.

The Ace

I know that, since you don't get the 4port in the USA, you are unfamiliar with its performance, but here in Greece (and Europe in general) we get both engines (6port and 4port). The 4port is rated at 192HP and 22,5Kgm, and enables the RX8 (with similar equipment and weight to the 6port version) to do 0-100kph in 7.2", top speed of 225kph, and the 0-400m in 15.2".

Well, after installing the Trust PowerExtreme Titanium exhaust and the REVi, I did some runs with my brand new GTechPro RR, and after some runs I managed the unthinkable

0-100kph in 6.97" and 0-400m in 14.98"

0-60mph times are even better, but they don't mean much for us metric dudes

I know that for most of you these times mean diddly squat, but for me these figures indicate that my RX8 is running beautifully...not to mention that I have mastered the art of launching (more easily done in the 4port, since its torque peaks at 4000K, so no need for 5K+ like in the 6port)

I don't have the runs in my office, so I can't post the screenshots, but if anyone is interested.....

I don't drag so I don't know if there are rules about how much gas is in the tank but by my calcs, base model 3029lb (I don't know if this is dry weight) stick with 238hp, 10 gal, 200lb driver (me), didn't count oil, I should get about 15.1 in 1/4. To get 14 the car would either have to loose 700 lbs or gain 62hp. To get 13, a little over 1200lb or 137hp. So, say with 1 gal, I should be able to get just about 15 even. Say I lost another 50lb by becoming a vegetarian, 14.99.

A 14.5 number would indicate HP of around 260hp w/1gal and 150lb driver.

All just on paper of course.

paper lies.
i was like 135 pounds at this time, had 50 extra pounds of **** in the car and half a tank, according to you the time was impossible O on top of all this the 8 really doesn't make 238hp its more like 218-220 at the crank.

I ran a 15.195 on Friday with 89 Gas & Mazdaspeed Exhaust. Going this friday to run with 93 Octane, K&N Air Filter and OEM Air Box Mod.

Good job Polak

Not impossible, not unlikely, just fun on paper. BTW: I got some weight numbers off of this forum somewhere and if you had the base model and with the weights and fuel you mentioned above, and produced the advertised HP from Mazda, paper shows about 14.7 for the 1/4. Not that I am going to go out and drag my new RX but I ended up deciding to get the base model and one of the reasons is the difference in weight. For instance, 100 lb accounts for about a .15 sec difference in 1/4 time for the RX (again on paper). That, of course, doesn't take into account the skill of the driver, condition of track, etc., which can make all of the difference.

I am awfully curious about the HP differences from everyone. It seems that most people get less, a few get more, some get fast with low compression??? I would love to see a boost out of this engine and like the elegance of the axial SC if it ever comes out. Did you dyno your car? I have never done that and don't know if I want to so I don't get dissapointed if the HP is low. Ignorance is bliss.

Lasse wankel

Hi Lasse from Sweden here. I Have a 2004 RX-8 with 14 000 km on it. Car felt stronger at 10 000 km more crispy. Anyway i have done some testing with the Gtech Pro RR and here are the results: 0-100 km/h 6.82s 1/4 mile 14.82s-153,1 km/h (95,1 mph). The following mods were done:Shell V-Power 99 octane fuel, Ferrita 2.5" race cat w 2.5" presilencer Motul 300V 15/50 engine oil Motul molybden mineral 75w/90 gear oil thats it! Maybe we should do a sticky on 0-62 mph (0-100 km/h) and 1/4 mile ET and speed?

15.022 @ 88.4...fucked up the 4th Gear Shift....but my best time yet.

Acclaim99

I want to bring mine to the track and run it, but I'm a little nervous about breaking something... lol.

Lasse wankel

Update on my RX-8: 0-60 mph 6.23s. This is on Bridgestone 245/40-18 S540 R tires. Launched at 5500 rpm with a little help from brake lever. This is with a G-Tech Pro RR unit.

Lasse Thats a great time with very few mods .
Best I did with only mod being cat delete was 6.33.
After a few mods i'm down to 6.08 - think I can get to 6.0s once i,ve finished all my modding in N/A form.

Lasse wankel

Then we have a race! First in the 5s with minor N/A upgrades Lol. My main concern now is finishing the equal length tuned header and dyno test it. Second the air intake is gonna be massaged!

are you 0-60mph or 0-100km/hr .
Mine is 0-60mph .

Lasse wankel

Mine is 0-60 mph! I dyno today with stock exhaust manifold and found only 241,hp. But torque was up from 196Nm to 200,2Nm. Next week i hope to have my performance header on the car and dyno test it on Wednesday.

RotorManiac

Lasse, you have very good times, well done.... 0-60 at 6.23secs is great but what was your quarter mile time?

when I used a friend's gtech I managed only ~6.7 or 6.8, can't remember now, but my 1/4 record is 14.47secs, pretty good I think. I was running on plain 95octane gas with stock tires... 60' time was 2.269 and 1/8 was 9.43secs...

Lasse wankel

Mine is also 0-60 mph. I only mannaged 6.35s today "dissapointed"

/Lasse

Lasse wankel

My best 1/4 mile is 14,75s@95 mph. 1/8 mile is 9.55s-76,7 mph. Whats your performance mods?

/Lasse

RotorManiac

back then, not so sure, but a few things... its been more than a year, damn.....the cat and the titanium cat-back, flywheel and MS sways definately, but no REVi, stock airbox with MS filter in it.... also stock rims/tires. check my garage
