Incase anyone is considering using a staggered T1-R/Forged rim combo, I had my Mazdaspeed 8 professionally timed/filmed during acceleration runs, and it resulted in remarkably low 0-60 and 0-80 times which I attribute mostly to the insane traction of the 265 section rears. The times were
0-60: 5.23 seconds
0-80: 8.2 seconds
for a naturally aspirated RX-8 thats almost unheard of, so if you are considering upgrading anything on the 8, start with wider/better compound tires

Here are some other links to awesome vids featuring the same 8 all profesionally filmed/edited with HD versions available:

t1rs aren't that good, **** toyo even has a better tire the r1r.

 

Then apparently there is the possibility of a below 5 sec 0-60 but I have yet to hear of anyone comming close. I still think 5.2 sec is a pretty damn good time for a N/A RX-8.

 

****** sweet editing if nothing else.

 

thanks man...feel free to leave comments/suggestions on the vids, let me know what you like and I can try and incorporate it in the next vid...we are also looking for other RX's so if anyone is in the Penn/NJ area and doesnt mind the odd hours of filming let me know and we can fit your 8 in too

 

That is an awesome time there aespo - are your tyres racing compound ?
I have to say your video titles are a little over the top but good work anyway .

BTW 9700rpm on the dash is more like 9200rpm actual . Have you had the redline extended by cobb ?

 

no I know there is speedo error I posted that title because just the image of reaching near 10k rpms is amazing. and yes its been extended by cobb

 

I enjoyed the videos, sweet!

 

I like the video and how did you measure the 0-60 times ??

 

the cobbtuning ecu re calibrator, race logic, and then finally cutting the clips down to the milisecond on a sony editing program called vegas pro which gave me exact times from the milisecond the speedo left 0 to when it hit 97 and 128, the digital speedo skips quite a bit under full acceleration though so i was conservative and got the next closest (higher) visible number, and calculated the speedo error to be near 0 at 105 kph...and to those who liked the video feel free to leave input and ill try and incorporate your suggestions into the next film

 

10,000rpm.... woa.

What have you done to your motor?

Spinning it that high definately put you in a more favorable RPM post-shift. Congrats!

 

Nice Videos But: not sure if you are getting those times in reality.

Also those rims are not forged, they are cast and quite heavy. They are the Ebay Stern ST-1's all over ebay.

not hating on yah, as i really like the videos. But no need to over exagerate either.

What NA mods do you have? Depending on ambient weather conditions you can gain a few horsepower from colder air. Also, I don't think our car gains a whole lot from extra acceleration traction as our car's ability to spin its wheel is pretty limited.

 

Have you ever tried a super-aggresive, drop-clutch start? I do these regularly at pro-solos, and I can say that my B-stock RX-8 has no problem spinning Kumho V710 R-compounds, which are super sticky. I'm not saying this is good for your drivetrain, or something you'd want to do regularly on the street, but your RX-8 is plenty capable of doing some serious burn-outs if you are willing to abuse it properly. Note that the OP was doing 8,000 rpm drop-clutch starts. I found with the V710s that anything above 5,000 was wasted, if memory serves me correctly.

 

Yes I know super high rpm clutch-drops will spin the tires, but then I'm not sure the extra grip is worth that many tenths in a launch. You want to have a bit of wheelspin as with our cars bogging is not a good idea.

I'm a little surprised you're reporting excessive wheelspin above 5,000 on R compounds to be honest. Maybe your RX-8 is producing more power than mine?

 

wow,

this thread fails on so many levels. all the really good timing stuff out there and we get this crap..

wow that race with the motorcycle, wow.. amazing..

going to stand with wow! this thread sucks.

beers

 

Alright fine I loved the videos, I'll admit that. The editing is quite amazing though I think I'd prefer to have generally longer shots. Is the OP professional?

 

Yes, the production quality of the videos is pretty good but the description given in the first post was over-the-top. Having said that, I'm glad the videos didn't show somebody taking their car to the limits on city streets, etc.

5.2 secs for 0-60 seems tough to swallow given the mods listed but the car was clearly hooking up, assuming the video is on the level. Car sounded great, anyway.

And Lion, it may have been 5500 that I dropped at, but nothing close to 8,000. But then I never tried it so who knows, perhaps 8,000 works better.

 

my car doesnt go so fast from 7000RPM- 9500 on 2nd gear -
why??? Is it normal ?? or something is wrong with my car

 

Sorry havent responded in months, if anyone is still paying attention or wondering for that matter, I can safely say that dropping the clutch around 8k yielded significantly better acceleration runs for my car then dropping it at max torque ~5500 rpms. Worth a tenth or two at least.

 

Videos are cool, very nicely done. As far as the times go, it would be nice to see some actual runs from a stop, maybe with an accessport so you can get the actual times.

Sorry if I missed it, but what are your mods?

Where in the NE are you? Those look like some nice country roads to have fun on.

 

The list of mods that I felt were relevant to the low 0-60 times are listed at the end of the video, and as far as the roads go yea they are pretty amazing, extremely tight technical roads are always great for the 8. The roads in the video however are spread out across NJ and Penn, took a while of searching before I found ideal roads for making the video.

 

An NA RX8 doesn't need super sticky tires to get a good launch, and that is not why you ran faster times than a normal 8. It is almost solely due the increased red-line. Keep this in mind: even though the torque output drops at higher RPMs, with the way the car is geared you will be faster up until the point where the engine is producing about half of what it would be if you shifted from 1st to 2nd.

 

I am aware of the gearing but I still attribute the lower times primarily to reduced wheel spin at higher rpm. You have a very good point though, most videos showing acceleration runs show shifting at around 8500-9000 on the tach. Considering that there is more or less a 500 rpm error towards the end of the rev range, the recorded times are well below what they could be if taken to the actual redline. If you watch the video again closely most of the time is shed between 0-40 before there is any shifting invloved which leads me to believe that it has quite a bit to do with the higher rpm launch and the sticker/wider tires.
