I guess Gord's liberal use of "slushbox" wasn't a strong enough hint? :D

Well that's good, because before not to long one will be available from 'down under' which will have jumping in sheer delight. :p

I'll be sure to keep you informed of progress here, but testing stages can get tricky, so be patient - as it is a virtue

so with spirits high we eagerly await!

Thanks

Hmmmm

Since a few people want to know if the AT 8 has a governor I will make a video the day of X~Mas for yall...

Ill show me going all the way from 0-125 mph to shut off of all fuel.

Im not complaining on the Governor as of I am not driving 125mph at all times.

Its just when I am on an empty Interstate I have the Need For Speed and it needs to be settled.

mr2000x

That would be fantastic if you could do that!

I wonder if you could also do a few runs to show how quick your gears engage with the paddle shifts.

I'm sure there'd be plenty of interest there too! :p :D

I went 4 a drive earlier and my gears seem to consistantly engage in under a sec,
so i was thinking perhaps i should make a video of this just to satisfy some curious minds.

Your videos would be a great treat, but remember

Safety First At All Times!

Thanks

p.s. Thanks again for your views in the poll, although i was aiming for just happy or sad with the auto tranny

Listen i've seen your sub box and its cool, i was thinking of one like this, but, i saw this one by 4080.

Since you know about these things - probably quite abit more than me!

Do u think this concept would sound good in the car?

Would appreciate any comments, thanks dude

You should see if you can rev match on a downshift. If you can, then your car is definitely NOT shifting instantaneously. If it could shift instantly, you would not have time to rev match on a downshift. The 1+ second delay during shifting is what lets me rev match on mine. There's a momentary delay before the lower gear engages where I can freely rev the engine.

mr2000x

Is this the same for when your shifting up a gear aswell?

Thanks

Like I said - that and the new 5 speed auto will be behind the Hi-Power engine. Same power as the current 6 speed manual. In other markets (ie where they offer the Lo-Power engine with a 5 speed manual as an entry level version), I expect they'll keep it. For North America, at a guess, I think the Lo-Power engine will be discontinued next year.

With the 6 speed SMG, it should be just as quick as the 6 speed manual - as long as they incorporate a launch system for max acceleration (ie to permit a high rpm clutch dump start to emulate a max accel. manual trans start). If that's the case, 0-60 would be around 6.0. I'd guess that a 5 speed auto behind the Hi-Power engine would be high 6 sec 0-60.

(It's BRG, for British Racing Green. That's the colour of my 96 Miata - hence Gord96BRG, the handle I've been using on http://forum.miata.net !) I have a 6 spd manual in the RX-8, a 5 spd manual in my Miata, and a 6 speed manual in my Audi allroad wagon. To be honest, I abhor the way auto transmissions shift when I don't want them to, I really dislike the disconnect of the torque converter allowing revs to drop independently of road speed when you let off the throttle, I don't like the lag from pulling a lever to when the shift actually happens, I just don't like the lack of control with an automatic. Fact is, I know better when to shift to suit me better than any automatic I've ever tried. Further, as a mechanical engineer, I have trouble with the idea of a less efficient (mechanically) device that doesn't work as well for me as the simpler, lighter, less expensive manual alternative. I think I could tolerate an SMG-type auto-manual, because it eliminates those concerns, but so far no slushbox has been able to. In my 29 years of driving, I've only owned 1 automatic trans ever (a 1972 Mercedes 300SEL4.5 that I owned from 1980 to 1983). I've driven plenty of automatic rentals and test-driven many various autos since, however, so I'm certainly familiar enough with their characteristics - and to know that those characteristics absolutely do not suit me!

Regards,
Gordon

I typically get a 1 second delay when shifting up, sometimes I get the large 2-3 second delays when I shift up while coasting down a hill. I get a 1 second delay on downshifts, but not the 2-3 second delays. There's not much of a point in revving up while upshifting, so I hope you weren't asking about that.

I test drove a Z4 2.4 with the SMG tranny and while it was not as much fun as a manual--it has its interesting merits--in an RX8 (assuming it would be as good of a tranny as the BMW SMG unit) it would be killer. I definately would trade up to that.

mr2000x

Hey simple, you never did say what spoiler u are getting??

Or is a secret till the pics go up??

Anyways i'm curious, what have u opted 2 go 4?

markd

Dlin, just curious here, but is there any reason why you decided to have all those mods but have the stock 16" wheels?? I personally would have moved up to 18s before making any changes to the body.

markd

Hahaha, that's a trip. I totally know what you mean, though. It sounds like you've already done the 0-125mph test before, but let me know if you find acceleration to be rather slow above 100mph. Seems like manual 8's dont have the same problem that I've discussed before in another thread.

Dlin23

hmm markd... well the thing is i kinda wanted to get rims but didn't know which one i really wanted. I hate the front of the stock look on the 8 soo i had to get a kit and now i am love with it like crazy. Also money was an issue, if i had enough i would get rims + body same time but didn't. Just patience =) rims will be on sometime soon(after winter). Once my wheels are on i will be sure to post pics.

Well I have gotten my rx8 to burnout at 90mph before.... This was on a simple downshift from 4th to 3rd at 90mph.... You should have seen the look on the guys face that was driving the Mustang Gt when I did it the first time...

I dont find my speed slowing down alot after 100mph... Just around the 120 mph range.

markd

Point taken. I have to admit, at first I didn't care about changing the front end, but the more I saw of the MazdaSpeed kit and even just the appearance package on several 8's here, the more I realized that the stock front end makes the car look small. That's just my opinion. I hear the MS kit is supposed to be pretty heavy, though, and I wouldn't want that affecting the car's speed.

Nice!

In regard to the acceleration, I don't over-speed that often (I'm actually beginning to somehow control my on-road aggression--tough thing to do, this being my first sports car), but when I do, I notice acceleration slows from 100-115 as compared to say 65-80. Something tells me that's how most engines probably are, but I'm not one to know any better.

DreRX8

if you say so kid.

First off, I love my Auto RX8 but......

I hate the fact that i've only got 4 gears to play with and really only two as far as reving the engine goes. Rarely do I get a chance to go above 80 (my choice). I wish they had found a 5spd Auto or something along those lines. Mazda knew everyone would bash the Auto, it was a quick stopgap until they could get something else for the tranny.

That said, the Auto is a blast to drive even if it is a little underpowered for a sports car. The car has so many other redeeming qualities, some of which you don't notice until you've had the car for a while. The interior won me over and I still find new things about it that I love. Everyone comments on how nice the interior looks and how comfortable the car is to ride in. The gauges are simply beautiful.

I'd like to put on the exact same kit that the superchanged RX8 had in that issue of Speed. That thing looks like it has teeth.

People who are not happy with their car are always more vocal about it.....

mr2000x

If u have any links or pics of this car

i would like to see them,

Also has anyone else had one of those 4080 boxes for the sub installed?

Thanks

Thanks for the link snizzle

I've seen that b4, never realised we were talking about that one,

wonder if there's a full story of that issue on the web somewhere!

thanks

snizzle

someone posted full scans of just the RX8 section, the very same thread I got that attachment from

mr2000x

For less than $5k leave the six speed rx8 looking at your rear bumper....and many others 4 that matter too

RX8rider

Can you explain what this is that you added and how it'll affect the performance. I'm kind of new here and I'm trying to learn as much as I can about mods and all of the tech talk. Thanks

Its to slow i tottally wish i wasnt an idiot and have waited for the 6sp
