thats all? wow, i see 1730-1740 range all the time in mine! hell i cruise north of 1650 usually

 

do you still have a cat ? could make a difference ....

 

^^ nope...

 

Wow - still NA right ? Is it leaned out via the AP ?

 

wait a minute, you see that high?

this is mine ( Using EGT Digital by Autometer COBALT) hooked up into teh manifold:
cruising:
5 gear - 4 - 5 K = 1240 - 1260 ..
6 gear , 4 - 5 k = 1260.....stays...

what do you mean by back to back runs? with and without while boosting?
steven

 

Yes I see that high - but this is OBD and maybe not accurate - don't know .
Have not tested cruiseing - that number was peak .

You do a (boosted)run with W/M operating and measure EGTs - then you turn off the W/M and do another run measuring EGTs . That way we can see what the difference is .
Also what ccs are you running ?

 

here is what mine looks like without w/m from 3500rpm in 2nd through to about 7000rpm in 5th. Boost is 10psi tapering down to 7.5psi at 8000 .
Temp in Celcius

 

i will do it this weekend, and i will record it too...

i am running Mazsport setting, i think 650cc two primary, and 780cc outside two secondar,,,,does it effect the EGT?
steven

 

cool

I was meaning what ccs water injection

 

sorry, but what CCS?
steven

 

The nozzle size for water injection ...

 

now you are talking plain english, LOL...sorry ....
i bought AEM methanol when the first time they came out, so i believe it was 130?

because the latest one, they change teh nozzle size, to 175...

i believe mine is 130. but i will check it again ,,,
steven

 

WOW Bret---so w/o your w/m on your egt's are 2000F???
Holy mother of side seals??
OD

 

damn, and he can takes it to 330whp? hahahha
but's that's good....that's hot though...

really? i never know.....what is the regular for rotaries?

because mine never pass 1260 F...sometimes it's 1270, but never see "8" for teh third digit,...

steven

 

I'm willing to wager that most if not all of you are using inadequate EGT probes and meters.

If an FI car doesn't see at least 1600°F at the ports, you have a gauging issue.

i am using above EGT sending unit....is it good or accurate? i don't know...
i follow the instruction where it should be mounted and the position of the sender..it was right on the manifold...
steven

 

The AutoMeter is crap.

This is a good one.

 

Your calculator is broken OD - 1745F not 2000 .

 

OH.
Ok.
I wear the dumb *** hat today.
I dont know why i was thinking he was at 2KF.
Peripheral port engine can see 2K but the rx8 in na form is suppose to be around 1600F--right?
Hey--this hat looks good on me for some reason?
OD

 

heh - we all wear that hat at some stage .

Paulm was saying 1700s for his NA but we really don't know how acurate the stock temp sensor is .....

Halim - did you do those tests ?

 

not yet, i didn't have a road to do the test....i will do it ASAP
steven

 

sorry to bump such an old thread but i was curious how much water/meth is injected per gallon of fuel? i.e. how many times would you have to refill a 1gallon or 5gallon reservoir per fuel up? I'm assuming it'll be heavily affected by the tune but I'm just wondering in general here...

 

I am no expert here but isn't EGT all relative anyway? Doesn't really matter how far from the port or what your numbers are as long as you can recognize an unsafe rise in temp?

 

around 1600F NA for me

 

mine is one gallon, it's enough...i fill it up every 2 months? and i start it when it hits 4psi...
i need to redo this reading, i wanna see it since i just fixed the probe...
