Here is the Conversation i had with my friend peter just Mainly about Rev limiters but there is also some other good stuff in there...

4:03amPeter

you nto doiung **** without fuel lol
4:05amMe

huh?
4:06amMe

do what without fuel?
4:07amPeter

turbpo hybrid
4:08amMe

ohhhhh

im gonna have a thrid feuel rail

6 injectors

it wont be for a while though
4:09amPeter

and what will controll it?
4:09amMe

all my money is going into school right now
4:09amPeter

that is useless tho i hopeyou know
4:09amMe

a secondary injector controller
4:09amPeter

unlss u got more power

and bigger turbp

nto hybrid

ust get l;arger secondaries

why add more when you dont need it
4:10amMe

because it already have a manifold with the rail on it
4:10amPeter

u dont get it do you
4:10amMe

remember?
4:10amPeter

u can add another injector with a safc neo

lol
4:10amMe

what do u mean?
4:10amPeter

nothin

;lol
4:10amMe

remember my car that wierd rail on it with the fuel pressure on it?
4:11amPeter

nope

i never looked at your car really

remember
4:15amMe

huh i think i would need a standalone if i went with bigger injectors
4:16amPeter

nope

nope

a neo can controll it
4:17amMe

how?
4:17amPeter

how

the same way a stand alone would

it's actually easier
4:18amMe

without a standalone?
4:18amPeter

cause the NEO has a auto tun or base mapping feature
4:18amMe

with an safc?
4:18amPeter

yes

safc controlls injector

duh

lol

like a stand alone

exactly like one

just transforms stock signal into the preset signal

you have asafc

right

installed with stock injectors

then you install bigger ones

and trim the bandwidth of the larger injectors

usually secondaries
4:20amMe

Safc doesnt controll injectors
4:20amPeter

yes it does fool
4:20amMe

safc works by modifying the air flow meter
4:20amPeter

OMG

and it controlls the fuel

that way

whatever lol

same ****

it is controlling the injector bandwidth

by means of flow meter

signal

which controlls the injectors
4:21amMe

right it modifies the afm and the stock ecu will cut the fuel think its open the way it is
4:21amPeter

SUPER AIR FUEL CONTROLLER

hello

lol

whichever way you wanna put it

same ****

it is controlling the injector bandwidth anyways

that what is it for
4:22amMe

the only problem would be the ecu would cap the injectors somwhere around 66% their max
4:22amPeter

it dosent controll the afm signal

ehhhh nm

the stock ecu still will do its same old precentage
4:24amMe

Have ever installed an safc before?
4:25amPeter

yea

i know

use bigge rinjectors

then you trim it

not mac it out

so the ecu dosent real more signal

it reads less

because with larger injectors they do not have to stay open longer

thats why you get bigger secondaries

hello

then trim

instead of richen

because just having the large on with stock parameters its rich

then u can trim instead of richen secondaried

you can keep primary the same

why do i even have to explain this

bro

you cant teach me anything so dont try

lol

whatyever you get it

get a stand alone then
4:27amMe

or have the stock ecu work

run a fully programmable AIC unit..

you dont trick the ecu
4:28amPeter

yea

u can use the neo as that also

somehow lol
4:28amMe

im not going stand alone
4:28amPeter

no u cant i guess

why not

power fc

or a pro V hks

those are sick

lol

all of them arte sick these days

self tuning

ude the hks f con and AIC then

i like that set up

when i used a fcon

it wokred pretty well

full RB

FCD

fcon

adjustable one

set to 8

andintake

**** was oosting 16 psi

lol

overboosting stock turbo

lol
4:31amPeter

i need the ps1000
4:33amMe

16 is pretty high for fcon
4:33amPeter

stock S5 turbo non ported

thats boost spike

it woudl hit 17

if non ported wastegate

it was ******* fast

then after about 1 yr blew the motor overboosting in 4th gear

80 mph it hit 17

and car was not accelerating enough blew a apex seal

high boost and slow acceleration is death for rotary

lol
4:35amMe

maybe u hooked the wastegate up wrong?
4:36amPeter

no

that what happens to good running S5 turbo II

when you put a full RB exhaust

and fcd

in 100% of good running S5

it is called boost creep

if you dont then your car is not running well

or turbo is worn

or it has a ported WG

every single turbo II i been in that is a S5 overboosts

with a fcd

because the stock WG is too small to bleed off the pressure at high rpm
4:37amMe

i think bad tunning would blow it
4:37amPeter

thats is why people port them

17psi

the stock system is leaning out
4:37amMe

not high boost and slow acceleration
4:37amPeter

14-17

it is not tuning

you dont get it

you didnt own or drive enough turbo ii to know yet

you will learn slowly

lol

trust me i been driving and messing with turbo rx7 for 17 yrs

everyone who knows rx7 turbo II well

will tell you no matter what

S5 with full RB exhaust

and FCD is overboosting

if the WG is not ported

and even then it still does a little

not as bad tho

i owned 5 turbo II S5 in my life

the first one

rx7-heaven bought lol

my driveterain is on his widebody vert

all S5

overboost

or boostcreep

no question about it

even racing beat says so

that is why you need a FCD

the stock computer cuts fuel at 9.8 psi i think

without a FCD you are leaning out and pinging

because of boost cut

so with the fcd

it allows boost creep or overboosting and tricks the computer ionto thinking it;s boosting less

when it is actually 14-17 psi at times!

crazy huh

that is blown motor medicine

u need more fuel brop

no matter what you think

u need it now

put a boost gauge on
4:43amPeter

http://www.racingbeat.com/resultset....rtnumber=11571
4:43amMe

having no FCD doesnt lean the engine - it is a fuel cut - your car isnt even going to spark when you are at 28:1 AFR

it will just mis-fire, not run lean and knock
4:44amPeter

argh

when it cuts fuel

you get a second of lean mixture
4:44amMe

and i do have a fuel computer
4:44amPeter

that can blow the motor trust me

i seen it happen

on my own car

white 90 turbo II

S5 all stock

just

full RB exhaust

FCD

airfilter

blown motor in 7 months

lol

planned to see how long it would take

i probably copuld have dont it faster

but it was hella fast during that whole time

see

the fuel is he same

at higher boost

with a FCD

stock is like 9 lets just say

9 psi

but now your boosting 13-15 and getting the fuel for only 9 psi

its ok for now

but your mixture is being lean

no matter what you think

make it shot

FC with FULL exhaust and no fuel enrichement is just asking for it pereiod

period*
4:48amPeter is offline.
4:48amPeter is online.
4:49amMe

i thought stock psi is around 6
4:49amPeter

no
4:49amMe

and im pretty sure bossting somewhere around 8-9
4:49amPeter

here let me find it

thats s4

se is like 8
4:50amMe

mine is s5
4:50amPeter

do you have a FCD ?

well i wonder why so low
4:50amMe

yeas i have a Rebic

rebic is a three in one Fuel computer + FCD + Rev Limiter Disable

also speed limt disable LOL or japanese cars

for*
4:52amPeter

yea

trust right?
4:53amMe

Yup oldschooll hahah
4:53amPeter

also i dont know what your taliing about

rx7 got no rev limiter
4:54amMe

Dude for real?
4:54amPeter

yea
4:54amMe

what do you think fuel cut is??
4:54amPeter

i taken mines when overbosting to past 8k all the wat back to 1.5

fuel cut id for when your care boost spikes
4:55amMe

ok try to take over that
4:55amPeter

is

not for rev limit

there is none on a rx7

take over?

fuel cut is only for overboosting

not rev limiter

lol
4:55amMe

dude N/A has fuel cut
4:56amPeter

haha
4:56amMe

and N/a engine has fuel cut dude
4:56amPeter

not turbo ii

not for over rev

idk about na
4:56amMe

yes a turbo 2 does too
4:56amPeter

i know it just dosent rev any higher

rev limiter?

no it dosent ****

lol

i taken a stock turbo II

stock ecu

past 1k rpm

back around

thats like 10k rpms

just with fcd f con and rb and filter

dude

its only limited by the ports

and exhaust

not the fuel cut

lol

thats why rx7 have a buzzer

no rev limiter
4:59amMe

wait i think ur wrong

the needle physcally can not wrap around

grab one of those cluster u have sitting in ur basment and try to move the needle it wont go past 8
5:00amPeter

dude

your dumb

trust me it will do it

i dont it

WTF

you just cant or never done it

kid im 32

been driving rx7 for 17+ years

trust me

u got a na tach in there

it will do it

trust me

it will wrap around!

you can ask all my rx7 friends who been there

your just too ***** to try

do it

watch it will do it

lol
5:02amMe

my car doesnt have a rev limter dude
5:02amPeter

duh
5:02amMe

my rebic has a rev limter cancel
5:02amPeter

no turbo II does

no rx7 does

maybe the rx8

if im wrong u can but me steak

lol
5:04amMe

i dont knwo where uu got the idea that all rx7's dont have a rev limiter

i remember arguing at ur house about that too
5:04amPeter

you are funny

watch

all rx7 rev hgh

if u got a p port

and stock ecu

it goes to 11k

todd ho does it

tony does it

na

turbo II
5:05amMe

dude sl on the gas for 1 hour straigt... it will not over rev
5:05amPeter

you have to limit a rx7

peoiple add limiters to rx7
5:06amMe

yea mazda did
5:06amPeter

no

thats why rx7 have ******* buzzers man

you dont know ****

they have no limiter

they have no limiter

so they can overrevv

while in a turn

they were made that way

its limited by exhaust

and port

turbo can rev high on higher boost

causeit can bypass the ports limits by pushing it in

non turbo needs porting

dude

street ported rx7 on stock ecu can rev to 9500

10k

with intake and exhaust porting

on a stock non modified ecu

i dont know what you think you know but its wrong

take it form someone who woned 34 rx7's

and still owns 3

we will argue forever

and while im revving at 10k smoking your *** in my turbo GTUs

you will find out

ou are limited by either your air filter

porting

or **** engine

idk

who gave you the idea rotary has a rev limitewr

fool

fool

they DO NOT ******* HAVE THEM
5:09amMe

im telling u they do
5:10amPeter

and you are wrong

100% wrong
5:10amMe

nope ur wrong

lol
5:10amPeter

lets make a bet
5:10amMe

ok
5:10amPeter

i get to peepee on you

lol
5:10amMe

lets make a bet
5:10amPeter

HAHAHA
5:10amMe

hella no

you buy dinner if im right

i buy u dinner ur right
5:12amPeter

ok fair bet haha

rx7 have no rev limiter

they just overevv and lean out

then blow a seal
5:13amMe

ok
5:13amPeter

they stop revving because the port limits flow

lol

go google and search
5:13amMe

can i post this on rx7 club then?
5:14amPeter

sure

ask if rx7 have a stock rev limiter built in that stops rev

i dont use the rx7 club

anymore

they suck ***

all noobs like you

lol

dude

watch

when i swap

my 91 turbo engine and stock turbo

into the GTUs

with full RB exhaust

ect

ect

i will show you it rev past 9k rpm

easily
5:16amPeter

https://www.rx7club.com/showpost.php...3&postcount=24
5:18amPeter

there are 2 sides on the forums too

yes and no

people saying ther eis a ignition cut

but i never experienced it

and my turbo II revved up to 1rpm

past 8 on the stock s5 turbo II dash

and henrys turbo II did also

but we did both have f cons

read thius dork

PALM SLAP!

lol

and thes e guys got 8000 posts

lmao

and they dont know

you all dont know ****

it is not a limiter

its jsut the rx7 running out of lungs!

the stock intake sucks **** man

a turbo II can go to 1 on the stock tach

and see S4 they know for sure dosent have a limiter

watch

read this

its about fuel cut and boost cut exct

and stock turbo hitting 15 psi
5:30amMe

yea but thats not a factory mazda manual
5:31amPeter

what do you think

factory rev limit is?
5:31amMe

yup

it sure does
5:31amPeter

whatdo you think

it is

i been past it

in a streep port GTUs

stock ECU and injectors

10k rpm

and my turbo II to 10k rpm also
5:33amPeter

argh

everybody on the rx7 clud are morons these days

im reading hella BS

lol
5:33amMe

I think you owe me dinner

lol

hey i want this stupid argument to ruin our friendship alright dude?

dont**

i dont LOL
5:34amPeter

lol

i dont owe you dinner

lol

yet

ima show you

whatever you read online is bullshit i hopeyou know

i never hit a rev limiter in a rx7

hit hit fuel cut yes

bot rev limiter hell no
5:35amMe

Fuel cut is a rev limmter... the ecu pulls fuel to limit the revs dude
5:36amPeter

no

on a rx7

fuel cut is only for overboosting

it reached a capacity

66% whatever you said

that not rev limit

thats fuel system limit

and wlet me figure it out too

lol

ima searching

ima have to call mazdatrix or rb on monday

lol

if you right

im not your friend anymore

lol

HAHAHa

ima rev to 10k rpm anyways

and show you off
5:38amMe

awww dude for real?
5:38amPeter

haha im iddiing lmao
5:38amMe

ur gonna let this ruin our friendship
5:38amPeter

kidding

what friendship lol

lol

ol

your funny

how could this ruin something lol
5:39amMe

lol i know but we have at meets driving around lol

fun
5:39amPeter

i can buy you dinner if your right

at mcdonalds

lol

its ok i can still drive better then you

haha
5:40amMe

this is true

u are a better driver

ive only been driving for 3 years

lol
5:40amPeter

i wonder

was it my s4 or s5

cause s4 dont have them for sure

3 ytrs

wth

lol
5:41amMe

yup

got my DL at 18

and im 21
5:41amPeter

lol
5:42amMe

and yes s4 do have them i my first seven was s4
5:43amPeter

my first 7 was a s4 86 sport

never revved that high

around 8500

all my rx7 8500

except turbo II

i had f con and it went to 1

watch
5:45amMe

my friend marc.. has a street ported n/a sport.. and with open exhaust only.. his limmieter hard up 7800 and the bangs at 8.. he could going up his power band but his limter wont let him (also known as Fuel cut)

hits hard at*
5:46amPeter

what car?
5:46amMe

red 86 sport u never met him
5:46amPeter

7800?

tat is low

i did higher then that

with a stock motor
5:46amMe

he went to the concord meet
5:46amPeter

full rb exhaust

streetable headers

silencer

hks mifflers

and intake

droip in kn

i did higher then that

wtf lmao

my gsl se revs to 8000

lmao

and dosent hit ****
5:47amMe

does it go past 8?
5:47amPeter

never taken it past

but i will now

try for 8500
5:47amMe

then ull never know
5:47amPeter

after i pout a full exhaust on

hell yes

it will

not with stock exhaust

but it hits 8 for sure

lets race

i think i can smoke you

lol

from 0-60

i say im pulling a mid 15

stock turbo II does 15 flat

so u got exchaust ect

u might be pulling 14-14.5

maybe faster

if u can drive it right

lol
5:49amMe

if u didnt have a rev limiter ur car can just keep reving eventually the flywheel nut will spin soo fdast it will lossen upp and the flywheel will slice through the floor panel and chop ur feet off
5:49amPeter

the flyuwheel nut cannot spin off

hello

its backwards threadded

lol

it will just shatter

lol

unless you have one that is balanced and billet forged steel

made for high revs

rx7 rev up to 13k rpm

with mods

idk about stock rev limiter

never hit it

just run out of power

then shift

but in ported

i been to 9

no power loss

and turbo II boost creeping with non ported WG back to 1

i wonder if the f con has anything to do with it

i doubt it

i doubt it

 

Damn, you saved all of that!!!

 

THere is more tooo it but i dont feel like posting it... He later goes on to say there is a rev limiter but its ignition controlled. He thinks it cuts the spark and not the fuel

 

Fuel & Emissions chapters, pages F1-77 (NA) and F2-75 (Turbo), Output Devices table, first line, Fuel Injection Amount, Remarks:

"Rear side; Above 8,500rpm; Fuel cut"

It is a rear rotor fuel cut to limit rpm.

 

That post just gave me a headache!!!

 

In my first 7 i used to rev the motor up to 9k ! LOL once you go past 8k your into carbon clean up mode. It came stock on all n/a fcs, but most owners don't use it. You don't make anymore power pass redline. Your just free spining the engine.. IN an N/A. Turbos are different since you have the turbo bringing in more air.

 

can i have my 2 minutes of my life back? i couldn't read past about the 10th swap of words

OP, he is right, you don't need more injectors with a hybrid turbo because it just adds another possible failure point reducing the reliability of the engine.

in the end, he seemed more knowledgable than you do.

 

damn son, almost a 2 hour chat bout this at 4 in the morning. Needa lay off that ICE.

 

Not even babelfish could make sense of that...

 

 

rotary is rev limited when it stops running because you kept your foot in it long after the buzzer went off.

 

What is this thread about? Cliff notes anyone?

 

TL;DR

Rotarys can spin to 30k if you take off the Rev Limiter. They rotate, not go up and down like a boinger. <--Fact.

 

OP, your buddy knows way more than you do man lol, AFC does control the fuel, you don't need 6 injectors lol, yes the s5 does over boost when you open up the exhaust (RB exhaust), i didn't read much past that, but in the end...YOUR WRONG lol listen to your buddy he knows his ****.

Says the guy with the pistons lol, but its true to a point, IF the keg is balanced to spin that high, along with a ton of other crap, like if the tensile strength of the stock components can take that rpm it will keep spinning.

Here I’ll state it better for you, the design of the rotary engine can have unlimited RPM’s.

 

the rotary engine is poorly designed and ultimately will be forgotten forever.

 

Automatics have rev limiters.

 

Does this post have a rev limiter ? Because I'm about to shoot someone... the stupidity in that first post is immeasurable.

 

Yeah that Peter Jun guy is a moron! Tried to call my Sport a SE. And still believes he know everything just because he is 32 or w/e. Like he really stresses how old he is makes him smarter then everyone around him. I wouldn't let him touch my car. Like really WTF? Stupid....

 

Well, give him a chance to mature a bit, and maybe he'll wise up some. Once you get old enough you begin to understand that you STILL don't know more than you know.

Only 32? I've been driving longer than he's been out of diapers.

 

ill just say this, peter knows his ****. maybe he doesnt understand the full dynamics of absolutely everything. no one does, not alan, not peter, not even aaroncake. BUT, these guys do know WAY more than even i claim to know.
as for the attacks on other people, calling names and such, sorry, but all of you guys, jonny, marc, daren, sean, YOU ALL have **** to learn, ALOT of ****. but, thats fine, if you continue to learn and grow, then thats what life is all about.
all i know is that i have alot to learn just to be able to do my monster REW swap and build my drift car the way i want.

Lloyd

 

im not reading this....

 

cliff notes!*

7s have rev limiters and fuel cut
no they dont
yes they do
im older and know more, stfu kid
no you shutup old man

posts thread

Lloyd

 

Lol!

 

With our combined knowlegde we can rule the rotary universe, but instead we fight like the Sith from star wars.

 

@DivinDriver. I know what you mean.
Like what Magus2222 said
YOU ALL have **** to learn, ALOT of ****. but, thats fine, if you continue to learn and grow, then thats what life is all about.
