i have a 2005 rx8 a/t...ive only had it a few months and i am very impressed with the torque when it gets around 4,000rpm.
but on the flip side...i am very disappointed with the lower end. even if i shift(with the manual overdrive) at 7,500rpm the next gear picks up at a low and slow 2,500rpm. is there any way to change this?

 

You can modify the shifting patterns, etc. with a device such as Access Port or Interceptor-X. There is lots of information about these products all over the forum. Try a search. ;-)

 

sell ur auto..

 

Or you can do the lower rear gear to help pickup down low a bit.

 

Rotaries were never known for low end Tq.
Now add a Snail or a properly designed and matched Sc, then you will see the low end Tq.

 

First thought was to ask what in hell your doing in the A/T section with your negative attitude then looking close I determined that you might be Military and that in my book gives you lots of latitude. Please note that the A/T is an option that some prefer and can be made to perform very nicely.

Dave, add properly matched Snail to your post. I have ridden in some turbo'd 8s (M/Ts) that are slower off the line than a stock A/T.

 

Easy Phil he's got racing beat screens on his car. Don't be going against him with your S/Cer.

 

I never "go against" anyone. Just wish to point out that having the A/T does not make you a second class enthusiast.

 

The Ignition Solution is a great way to add a little kick to your 8. It will not cause and check engine lights and will increase your horsepower. There is a thread about it under "Major Horsepower". It is an easy install and a good value when you consider $$ vs. HP gain and other alternative products.

 

The problem with a rotary having low torque is based solely on one thing and that is engine size. It's a small engine. It won't have lots of low end. That's physics.

There are a couple of ways to get around this. One way is with help in the form of forced induction. Either a turbo or a supercharger. For an auto I'd personally lean towards the supercharger but that's just an opinion.

The other thing that can be done is to never stay at lower rpms. I understand that the transmission shifts and send you back down there which is a problem. without being able to change the auto transmissions gear ratios, the only real way to get considerably more low end is with forced induction.

 

Just for the record, up until last year, the autos had more torque all the way to 7500 rpm than the manual transmissions did so I don't really think he'd want to downgrade to yours.

 

lol.. fine, but still. manual ftw XD.. shift at 9k = never low rpm.

 

hey F, glad to see you are still around. did you get hitched yet?

 

April 25, 2009 is when my warranty runs out.

 

holyshit, laides get your bills out!!

 

You can put it in manual mode and it won't upshift at all until you tell it too. You can even bounce it off the rev limiter and it won't upshift.

I drive with it in manual mode most of the time, for exactly that reason. Most of my around town cruising is in 3rd gear. That way it is quicker to respond when I need it to. Generally I don't shift up to 4th unless I'm cruising above 50 mph or so.

 

Manual mode.

 

I'm the exact same way, I try not to go to 4th until I'm over 50mph unless I'm trying to save gas which seems to be a lot lately because of gas prices. I was tired of doing the 4th to 2nd jump skipping 3rd which would give more than I need so cruising in 3rd seems to be good. Do any other people skip gears in their auto or is it just me? 4th to 2nd anyone? you can also go 3rd to 1st depending on speed.

 

Yeah, I'll occasionally do a double tap.

 

That's what she said.

 

Re-phrase that to "The 13B-MSP engine is not known for low end torque"

Because the 20B-REW in a Cosmo pumps out almost 400NM at just over 2000rpm

As for the 13B-MSP, drop a gear or two, let it rev & enjoy the smile-on-ya-dial. I certainly do

REgards

 

Ok you got me there! You and your 3 rotor.....




Phil,
Here's my snail.

 

I like your "snail". I'd say something smart but the turbo lovers would think I was demeaning their choice of FI.

 

I didn't know you could get minerals out of a turbo.

 

I guess you can if you can't spell.
