no le. i didn't change my exhaust. its stock, or at least i dun see anything that shows its not stock. you know Re-con cars. hahahaha

 

mr. kenji MIA ah.

he running on 16" but his 6 exhausts plus 2 "wings" makes up for the weight.
LOL!

 

BlackEight have a point there, are those 10 seconds cars bodykit'ed?
weight ratio?

 

Possible... if the car lost 150kg plus running on 14inch rims

 

I have already posted how to get good straight line times in one of my previous posts. And i think i was replying to one of your posts. And i am quite sure you know how to get good timings too.

From this thread, i already see one big mistake. "Passenger time my run"

And ditch the BBS (brake buay stop) rims.

Wah! 10 secs AT 8. Toyota altis seems faster.

Straight lines doesn't matter much. Its what the driver can make a car do and not the car that drives the driver.

 

One reason I can think of:

The new AT8 comes with Renesis, unlike the old ones.

 

INXS: Well, first gotta meet up at one of our meets first. Haven't been able to meet you yet... ha ha.

LsBlack: Boss... you free or not first? Anyway, Wednesday is not good for me. Ex-girlfriend's birthday. How about Thursday?

BlackEight: I believe a TC'ed 4AT can hit ard 6 to 7 secs and a ECU remapped final drive 4AT can do 9+ secs. I don't think a ECU/FD mod can drop 2 secs from 10+ to 8+ secs for such a short sprint.

PitchBlaC: Well said.

rx8-8888: some have tested it and it's quite good, but so far no definitive testing for hard results.

 

Hmmm... Id love to test it out with/in your presence. These two weeks beh sai.. ICT 14th - 26th. Buy you ice cream .... haha.. Arrange after tt?

Meanwhile, any AT8s here wanna input anything related to this discussion on How and WHAT has been possible for your rides best achievement?

 

Silver_Z: Same Gtech Pro used on all runs. Slight inaccuracies possibly due to assumed standard weight (used the weight of my car when I weighed it last year + half tank of gas + average driver weight), default suspension dip, rpm calibration, etc. But the inaccuracies are applied to all the vehicles tested.

CoupeM: Anytime we can meet at the next post meet-up event. It'll be my pleasure.

Emperor: Yup, all the tips for better sprint times are excellent. However, still none of the NA 4ATs tested has gone under 9 secs and only 2 have broken just under 10 secs (9.99 sec).

INXS: Stiffer shocks help to put the rubber on the road as do lower tire pressures assuming rims/tires remain unchanged.

theboy: Don't get me wrong, it's not that I don't believe your timings or that I'm out to prove you wrong or anything. I never want to stand in the way of truth. I just want to understand how you can get under 7 secs on your 4AT which is similar to a Z's time. youtube video is useless because we don't know what mods they are running. What do you use to measure your timings? Would be good if you could get a Gtech to measure your runs and post the PASS files. If you are using some kind of stopwatch, can you try measuring with a different one? I remember I used to run my 2.4kms under 11 mins until I realised the stopwatch I used was counting slower because the battery was low.

I don't know if smaller rims will make a huge impact on the times. Smaller rims usually also mean narrower tires. Might help a bit on the 4ATs because they don't usually wheelspin at launch, but 6MTs will definitely fishtail on the launch with less grip which results in slower times.

 

i totally agree what u mean, thats why i am trying to get my friend to photo take the result on his car for me. he installed some device that u can see the 0-100 result precisely, cause he is driving type E auto stock like me.

 

Cool, appreciate your open-mindedness. Let us know what you find out. Maybe there is a way of getting better times that we don't know about.

 

Was it also used on the 6MT that got sub 6s? I mean, is there a chance that the fault did not lie in the driver or car, but instead the Gtech Pro is faulty thus giving a reading with discrepancy of +4secs

 

I tend to agree with sqflyer and coupe07. Over the past few months I've been to quite a bit of mini-gatherings at tuas, yishun and jurong port where a number of different makes do century sprint 'mini-races' and timings. believe it or not, even the Z and WRX do not have the 0-100s that is advertised in brochures. The Z for e.g. is definitely above 8s closer to 9 actually. Similarly, the wrx (full exhos mod) is mid 7s.

My 10+s timings is with stock intake and autoexe exhos. I haven't timed since i installed final drive and stuff. but to answer theboy's qn:

(at that time in May)
1. Engine oil: RMagic
2. rim size and tires: 18", AD07 (note that even i felt a diff between 16 & 18" at change)
3. Fuel using, how many ron: SPC 98
4. Ecu remaped: No. As Coupe07 says, ECU is NOT for better launch times rather, better temp management, smoother and smarter shifting

If the RX8 AT NA really can do 6-7s, i think you can start taking on the RSYC gallardo races - may lose but will not sia sway yourself liao

 

The manufacturers figures of 0-100 are mostly unreliable. Mostly too optimistic. All manufacturers do that from fiat to ferrari. They may do timings a thousand times and give the best readings or even correct it to compensate for variables. So if they got 7.1, they correct it to 6.9 due to variables.

It also depends on testing conditions. Cool and dry weather naturally gives better timings. Tailwind vs headwind. Lab testing and not tested on road/track. Calculated figures. etc.

Proper runs on open roads should include runs in both directions. There may be inclines / declines not visible to the naked eye.

And it actually wrong to just floor it all the way; proper way is somewhere 1/2 to 3/4 then pedal to metal. Plus there must be some wheelspin to get good timings.

 

I so agree with you Emperor, alot or most of the car companies just luv to exaggerate about their "accelrate"tion........hahaha

Can't remember which program I watched, the 6MT 8 can match the time if the current E46 M3 as well on the track, so which is which actually?? A relatively slow M3 or a relatively fast 8??

 

Wahahahahah...11 & its been counted slower..Tats a good 1
Hey Happy Birthday Mr Flyer's Ex-Girlfren...
To make things easier, anyday is fine...c wat the rest say

 

the record holder has spoken.....hehe....a little yaya....but i like

 

Bro.., coupe 07 ve mistaken la
I am the record holder, not for timing but sound effect
But ...no explanation needed here rite
just feel so shiok able to yaya papaya

 

Silver_Z: First let me clarify that the 6MTs managed 6+secs (close to 7 secs) and not "sub 6secs". It is NOT EASY to break under 6 secs for stock NA car. Next, to answer your question. Yes, I believed I already stated that the Gtech Pro was used on ALL RUNS, meaning all 4ATs and 6MTs. The 4ATs consistently recorded 10+ sec timings and the 6MTs between 6+secs to 8+secs (variation due to driver skill and launch techniques). While I agree that any device can fail or give faulty readings, I do not believe this was the case. If it was so, then some 4ATs could also get 6+secs to 8+secs timings and 6MTs could get 10+ secs too, right? That didn't happen so I believe the Gtech Pro was functioning properly.

derekwcw: The Top Gear review of the RX-8 gave the same timing of 131.8 for the M3, 350Z and the RX-8. Shows the handling and cornering of the RX-8 on the track makes up for it's lack of muscle. However, the topic of this thread is century sprint timings.

LsBlack: Thought of suggesting tonight to see how committed everyone is, but it started raining and doesn't seem like it's going to let up and dry off.

 

Thks for the clarification. Its hard to believe that the discrepancy is so wide. Hopefully the 6AT is different. I will volunteer to do testing once I collect and run in my ride, at the end of this year.

 

Wouldn't the gear ratios and shift duration play a big part in the times as well? I'd imagine that a flat-shifted manual box would be tenths faster per shift than a slushbox.. I would have thought the difference would have been closer to 2 seconds rather than 4 though, but the GTech pro is a reliable piece of kit.

 

3 NA 4ATs tested their timings that evening with timings ranging from 9.1 thru 10.5. Here's what we found that was interesting - the discrepancy of over a sec is really due to how and when we shift gears. In my first run on either fully auto or shifting at redline (7800 thru 8500 in multiple runs), timings was consistently at 10.5 thereabouts. But when i did a run shifting at 7k, we clocked 9.5. Derek clocked 9 using the same style. This speaks a lot for mythbusting siah - the car is not necessarily peaking at higher rpms.

 

1st of all i would like to apologise for my late post. because i had not got the G-Tech from my friend which i am supposed to post the result here. tired using a camera but it wasn't shake proof and i did swing my friend back to the seat when i boost at 1st gear. i got another idea which is sticking a camera phone on it.

well gfoo, i know u had been here for a long time, i respect that, but i think it was the driving method u used. 1st the fully auto i also recorded at 10 second. but with semi its totally different story. u do not bosst your second gear to redline, 1st gear 7k , 2nd gear 5.5k, 3rd gear u should be there, 2nd gear can drag your time 2-3 second thats what happening here

 

theboy i think if u read my post carefully, i'm actually agreeing with what you're saying. U r right, it's all about driving style. In semi if i dun redline n shift at 7k my timings was mid 9s. I didn't have to shift to third as 2nd gear hit 100kmh liao. I'll try yr method of shifting at 5.5 2nd gear next time if we have a test again.

 

cool bro. its a great sharing.
