I bought a G-tech Pro and I did a few runs in my wife's automatic RX8.

I think many people wondered about what time the auto would run although we all knew it would be horrible due to the fact that you can't launch it properly and it has a lower hp engine.

Well here is my best run of about 10.

(Note: the G-tech was caliberated correctly and I just floored it from idle. I DID NOT use the brakes to raise the launch RPM although I know this could have netted better results, I do not want to abuse the tranny/brakes.)

60 ' : 2.785
330 ' : 7.353
60 mph : 9.355
1/8 mile : 10.981 @ 69.62 mph
1000 ' : 14.066
E.T. : 16.667 @ 87.44 mph

I shifted manually with the paddles at the buzzer. The windows were rolled up and AC off in the night time, it was pretty hot and humid though.

When I did it in D (drive) with the windows down I got 16.8. It shifts below the redline to protect the tranny I guess. I had to redline the **** out of first to get 9.3 0-60 mph from idle. The tranny did not sound happy above 7000 rpm. I still feel that the car has a strong 15 second pull especially at the top of second. It is the launch that is hurting the times. Somebody please rape your AT and pull a high 15!

 

wow, very very nice. i had some reservations about ppl saying that there was a very very large difference between the auto and the stick, as i've driven both...nice to actually see some evidence! nice work

 

Well the 0-60times I recorded on my car w/o Dyno or gtech musthave been way off b/c I didnt know the speedometer overrated how fast you were going by a few mph. Prettysad that thats all we can do. Oh and didyou ever time it w/a brake rev launch?

 

I think your numbers are very good for a rolling start! Good job!

 

Nope, but I am sure it would help.

 

do you have the M- flash- doesnt that help the auto in low RPMs?

 

I'm gonna catch heat for this, but I am 100% sure that no stock RX8 auto will ever dip into the 15's in the 1/4 mile...it just won't.

I bet you could have clipped maybe .4 seconds by brake torquing the launch....

 

Dude... give it a rest...

 

Sorry Kevin...I really did not mean to offend anybody.

 

Don't appologize man, if the AT owners have issues with someone stating the truth it's their own problem. They need to face facts that the AT just isn't that fast... It's like telling a Corolla owner they have a mid 16-17 second car and them getting upset, IT'S THE FREAKING TRUTH!

 

I dont think so.
An auto SHOULD be ablt to hit a 2.1-2.2 60', which would put him around a 15.9

You cant say its the truth, because you dont know...its called a geuss. None of us know and none of us will know untill an auto owner with some ***** break torques the car.

 

Not to argue, but I haven't seen MT times that get 2.1 60'.
(OK I think I saw one or two, but they were rare, more typical were 2.4-2.5). So I really doubt an auto with the existing stall converter is going to get 2.1.

IMHO, there won't be any auto times in the 15s without mods.

 

Watch it buddy....

 

Never stated I have a problem, its the people that have to keep "proving" their 6sp is faster than the auto. I know the auto is slower than the 6sp 8. Hate to say it by my 6sp Miata would give the 6sp 8 a run for its money too.

I'm cool with NAVILESRX8, we are on the same page. :D

 

Next time I see ya, you'll get your hug.....:D :D :D

 

Guys letsbe honest here. Somepeople w/the stick Rx8 cant even get below 15 sec w/their 1/4 mile times w/o dropping the clutch at over 4000 RPM. So if the stock auto canreach a 1/4 mile time in the mid 16s from a regular launch Ithink thats pretty realistic consideringhow much slower our horsepower and 0-60 times are. Maybe w/a brake rev of 3000 RPM someone will reach the low 16s. It wontbe my car b/c mine wont go past 2500 RPM when I try that. Low 16s wouldbe pretty good I would say. It seemslike the auto Rx8 1/4 miletime is around 1.5 seconds slower than the manual Rx8. That soundsabout right to me. Ihave nothing to complain about there.

 

My car came with the "L" flash. I will try to upgrade to "M" although I doubt it would make a difference performance-wise.
You guys make me want to brake rev my wife's car. I am 100% positive I can get a low 16. And I want to clear up one thing. When I ran 16.6 @ 87 mph I had a full tank of gas, a spare tire kit, some tools and cleaning products in the trunk, like 200 cds, and 18 inch rims. So to say that you can't run high 15s in the auto stock I think is an uneducated guess. Let me clean out the car and brake rev it!!! I bet if I run a real low 16 there will be questions about the accuracy of the Gtech Pro. Remember it is properly caliberated and supposed to be accurate to 1/100 of a second. Also do you guys think the mph is pretty high for that time? I thought it kind of was. Remember many 6 speeds are running 15s and I think a base automatic with 16 inch rims can hit a 15.99 when launched with some rpm and it has 41 less horsepower and 2000 less RPM! I think for an automatic N/A rotary it runs respectable. And from my personal experience ( I am a racer stuck in my wife's automatic) it will give almost anything on the road a hell of a run from a ROLL (weight is moving, RPM, rotary powerband, aerodynamic). Even from a slow roll downshifting to 1st and redlining second feels very peppy to me and I own an FD. The only thing that sucks is from a dead stop (no rpm) and 4th gear (no power). Remember it is a cruising car and it does an excellent job of that with a refreshing burst of N/A rotary pull every now and then. So everybody bow down to the 6 speed and please respect the auto.

 

The new GTECHs if properly set up are pretty accurate.
But thier trap speeds read higher than a trackc.

 

ikewrx....i dynoed my auto z( i know it's not an 8 but it's an AUTO)...and it dynoed at...

CF:SAE Smoothing: 5

230.88 ( this is edited...i stated 330.88 by mistake!..apologize for the error) horses and 228.91 lbs of torque...i don't think that's too bad for an auto. Sport cars like ours are made to perform well...whether it's an manual (which I dearly miss) or an auto. So numbers between an auto and manual shouldn't be far off. And most z owners do not know how to launch their cars correctly therefore my z is usually faster (no shifting mistakes)<---i'm sure this topic has been beaten to threads so i'll stop right here.

then again rotory is so unique...so i wouldnt' know...my 1 cents

 

A dyno is made at wot, right? How did you dyno an automatic without it downshifting?

 

you mean 230 not 330 right? the graph reads differently.

 

I sincerly apologize and feel very dumb. YES 230!!! not 330 horses...must have been my unconscious power aspiration leaking out of my brain.


neit-jnf...i don't know if this will answer your question but "auto stick."...up to 4th gear 1:1 ratio?...something like that

 

I guess I'm not one of those "Somepeople" :D


Car #202...

 

In a few hours I will be G-tech- ing my friends automatic FD. It should be a sub 14 second car because it has exhaust. Will keep you posted.
