I'm convinced its EGT due to empirical evidence, no need to convince me.
sorry i read ur post wrong, i thought u sed u think they fail from wheel speed alone...
-
damn those school holidays HAHA
-
i have for sale the following
walbro intank 500hp fuel pump used for 20,000ks with bracket etc after $100.00
and the in tank fuel level sender unit, after $50.00
pm me for offers
reason for sale is im no longer using a fuel tank, i have got a custom fuel cell, and 3 bosch 040 pumps hanging off it
-
which is it mate, theres a difference. a 32gtr crank needs a collar if going into a 33gtr...
on that note i need a 33gtr crank so if you hav 1 sell it 2 me!!
-
I've got a rb20det turbo laying around but not willing to waste it on this experiment, as I don't feel ceramic turbines fail from wheel speed alone.
thats your perogative mate.
i know for a fact that the egt is the cause and all i was doing was offerring a chance to prove it to you all
-
go for reliability before power i say. turbos then fuel pump ecu injectors, THEN cams etc
-
as it states, single or full set not fussed, pm me if you have any
-
and if anyone has a spare ceramic wheel and shaft lying around, send it to me and i will put it into my machine and spin it up to 300,000rpm and leave it for 10 min at that rpm, then i will apply heat for 10 min with the assistance of an oxy torch with accetelene bias so as not to melt the thing.
open to offers. i will record the findings on video
-
Actually I won't accept it unless you provide the physical evidence and a significant enough sample.
You said the shaft expands, not the shrink fit of the turbine onto the shaft causing excessive hoop stress.
Methinks you are not an engineer at all and have decided to run and hide.
I have not heard of one rupturing off boost.
i never once said they will throw a wheel off boost, i said the damage occurrs during that period. the wheel will throw once spooled.
thankyou for the comments, but not good enough im afraid
-
def turbos... then ecu and injectors
-
poncams are good because they use the stock valvetrain.
if you want big power you will need more lift and around 264 duration..
procams are better, but you need to change valve springs, retainers etc
for a stock gtr (internally) cams wont really give too much benifit. ive seen stock cammed gtrs running 600hp with no problems. attend to other parts 1st, such as turbos, ecu, injectors zorst etc
-
depends on the setup.
usually more lift = more flow, but you also need duration. the problem lies in getting a good combo as at high rpm you can get valve slap, eg over revving. to compensate you can use tougher valve springs etc. but it depends on the lift. if the lift is more than the springs can take the springs will bind, or over compress.. VERY bad.
if you need high revs eg nat asperated, you need less duration more lift... to raise the rev range
use as a guide as this may not be correct to some out there
-
lift= mm valve lift
duration= how long its open in degrees
timing= difference between inlet exh lift
-
as i said, i need a front bar for a r33 s1 skyline
preferably r400, but atm any will do
damaged, undamaged i dont care, as i need to modify and respray it anyways
thanx

i think its so you can bleed the line easier
-
anyway, i have had my say as previous in this thread, so read it, make your own decision. this theory has been tested though, so accept it
time for work:(
-
its not so much the wheel heating quicker its the wheel COOLING quicker than the steel shaft, causing the damage
-
whats the point of a radar detector. if your speeding, adn you get picked up by radar, the coppers allready know ur speeding, so whats the radar detector guna do for you???
it detects the radar emissions once they hit the car. TOO LATE!!!!
-
its a resonator, used to take the "lumpyness" out of your exhaust sound.
so basically yeh, its for emissions
-
cubes i was thnkn the same thing, but i couldnt be f**ked typing it HAHA
-
i agree
-
But then theres people like 2rismo running 11's on the standard turbo
hes obviously running wih an exceptional tune, and/or an auto.
drag racing is wot for hopfully 6 seconds
constant heat and stress causes failure

yes they interchange
