you know iam wondering if this is really worth it... especially if persay someone liked to have fun on highways . now I know 3rd tops out at about Oooo 130-135 depending on how high you take it and then you hit that super tall fourth gear which is where the car your racing whoops your ***. So what iam wondering is would the 4.10's or 4.30's (whatever) have a better or worse effect on top end??? btw if I change gears wtf can I use adjust the speedo?

p.s. I make 310whp on my auto

 

because most people have horribly mechanical luck with the auto tranny FDs come with.

there you go, the end. most people blow them up one after the other.



and ******* FYI, a 3000 STALL does NOT mean that the tranny doesn't see torque till 3k. same for any other stall speed. jesus, ******* newbs, welcome to how torque converters work.

Always, before you go flapping your lips about how something works make sure you know what you are talking about. RXASSASIN7, I recommend you start being a bit more careful with your posts before nobody on here takes you seriously any more. Would be a shame for you to lose such a valuable source of info.

 

thaks for blowing it for me guys I could really use the dough! Do you even own an rx7? Look on page K-11 in the 1994 FSM. Stock stall is listed as 3000-3300 rpm. You can also look in the yamaguchi book on page 88, where it is listed as 3000. I wish I had the time and energy to scan it and spoon feed it to ya, but I 've wasted enough time already.

 

yeah the 4.10 or 4.33 would lower (in theory) your top speed. i think in reality top speeds are drag limited. you might enjoy this link (go about 5 posts down):

no no what I mean is would it effect your acceleration lets say from ohhh..... 120-160 or so. I dont really care about my top TOP speed its my acceleration at high speeds that I care about.

 

a) all rx7's have factory stall @ 2200rpm
b)if you dont know that you need to call Dacco and ask for the stall speed on a FM68 that is your torque converter code (fyi)
c)why don't you stop reading books and mags like a little ***** and work on them then you would know the converter code moron... newbie my *** ... wheres my money bitch ?????????
d)the stall has to do with how much fluid it takes to fill the converter and apply the impeller fans in order to boost the torque capacity of the transmission.
f)if you slam the gas to the floor you would not see full torque cap. until 3000rpm, which means as same as riding the clutch and dumping it at 3000rpms

god if im the newbie what the hell are you?

what good is resources on here when they are incorrect? why am i the *** hole for disagreeing and fighting the conversation for truth?

 

cant we all just get along?

 

cant these guys just get it right?

 

hey r...
Shame on you, dueling with an unarmed man. lmao.
Thanks for your post with this link - good info http://www.scuderiaciriani.com/rx7/differential.html
im really pleased with the 5% performance difference ive gotten from my recent switch from 3.9 to 4.1, but i not surprised after checking the comparative ratios and doing some math.
heres the bottom line: any way one chooses to perceive it, the FD in good running condition and in its many shapes, forms, and configurations, is one of the most exhilarating, kick in the ***, fun cars to drive, not to mention its beautifully sculpted appearance.

cant wait to hear you say: touche' en gard! ...............

chuck

 

Sorry, I should have known. You are right and the rest of the world has no clue WTF they are talking about. Please forgive me for flapping my lips about something I have no clue about.

 

Thanks weaklink for that link, i've looked through scuderiaciriani before but never stumbled upon that. I know what my next mod is

 

It's clear to me that you have no clue what you are talking about, and worse, you're being an inflammatory *******. I referenced those two books because ONE is the FACTORY manual and I think Mazda knows more about their torque converter than Wacko. TWO the Yamaguchi book was written WITH the engineers who developed the 3rd gen and so I think they also know more about the torque converter than anyone else. However, these may be mute points as I'm beginning to think that you CAN'T read. THREE I drove around with a 3500 stall converter for 8K miles, so I know what it's like. The whole purpose of a torque converter is to help get the car into it's powerband, which on the rx7 is considerably higher than 2200 rpm.

 

yes it would improve your acceleration at those speeds.

 

first you said that it wont see ANY torque till stall speed, now you are saying this ****? make up your mind, are you totally completely wrong, or just wrong a little bit?

i can't believe you don't know what the Yamaguchi book is.

 

This reminds me of that line from the movie Top Secret: "There are no good white basketball players, my friend."

 

Very True

 

You're wrong.

A transbrake is a modified valve body that allows simultaneously engaging 1st and reverse while the button is depressed so that the output shaft does not spin. This puts load on the engine so that you can build higher rpm/boost on the line without pulling against the brakes. When the button is released, reverse disengages immediately and the car launches extremely hard as power is suddenly applied to the output shaft. Transbrakes are not a universal device that works on any transmission like a line-lock for brakes.

 

Sorry to break it to you, but there's fluid being pumped into the torque converter whenever the engine is running, which in turn drives the trans. oil pump.

First of all there's only one impeller, not 2 or more as you seem to think. The torque converter has an impeller, stator, and turbine. Furthermore "stall" is when both impeller and turbine are spinning at nearly the same rate (the impeller will always be spinning slightly faster than the turbine, hence the poor mileage charactistics of the average automatic transmission). IIRC, technically "stall" is a condition when the stator begins freewheeling and no longer applies torque multiplication to the turbine.

 

This isn't a flame, but we need to clear up your ignorance. The stall speed is the highest RPM you can achieve without the car moving not the lowest speed at which the torque converter transfers power. Stall speed varies directly with the input torque. This is why you see higher engine RPM with heavy throttle than light throttle. My 1972 Dodge Van has a factory torque converter that is about 11.75" in diameter and stalls at about 1700 RPM behind a stock 318. Does that mean the van doesn't move until 1700 RPM? Not at all.

 

a good thing about the auto for dragracing is brakeboosting

 

Good point up above. FD is not a 1/4mile car. It was built for tracks and corners.
Use it what it was meant for

 

Tell Ari Yallon that.

No car comes from the factory built specifically for quarter mile use, but they can all be run at the drag strip just the same. The FD included.

 

they probally do, they just arnt on this forum
