So I picked up a greddy egt gauge but no turbo...i was curious what sort of temps the b18c1 was used to seeing in a completely stock environment

here is my setup (2000 GSR):
intake: stock
header: stock
engine: stock
cat: stock
exhaust: stock
ecu: stock obdii
running 93 octane

its pretty much stock y0

except for the bird poop

conditions
75degrees F
49% humidity


EGT probe installed about 3" away from head on #3 runner

80mph highway cruise: ~700C

4th gear 50mph cruise: ~600C

WOT from 80 to 90mph indicated: temps drop from 700C to 680C (ecu goes into open loop, running richer)

WOT in 3rd,4th,5th from 50mph to 100mph: 680C climb to 720C at 100mph.

720C was the highest I could make it read.

Do you guys see similar temps at cruise? When I get to 1/2 tank i am gonna put 89 in there for a ~91 octane mix and repeat the test in similar conditions.

Also, without that stamped head shield, man the AC lines get HOT.

 

alright well i am glad yall enjoyed my post.

 

Hehe, good stuff, nice to have a reference from which to base our numbes on. I need to hook up my damn GReddy EGT gauge already

 

falconGSR: so what kinda egts do u see
DIRep972: right now im seeing 800
DIRep972: with stock timing and FMU i used to see 750
falconGSR: does it stay there or is that the peak after slowly climbing
DIRep972: it climbs fast but it peaks right around 800-810
falconGSR: and your probe is in the revhard manifold?
DIRep972: no
DIRep972: in the internal wastegate
DIRep972: hole
DIRep972: in turbo
falconGSR: ahh
falconGSR: thanks

 

good post joe. Im sure theres other people who were interested in knowing what the stock EGT's read as well. what were ur a/f ratios on those pulls?

 

mine peak at about 800-850

 

whats ur set up? and timing?

 

Damn I need an EGT gauge. If it helps my factory water temp gauge goes to about the 3/4 mark close to the red under hard boost on the highway

 

Very interesting joe.

 

I have always been curious to know what the stock (non-turbo) EGT's looked like.
Hard to believe that a turbo only changes the readings 50-75C.
Thanks!

 

good data collection, thanks for the insight, cant wait till i get my guages!

 

good stuff

 

thanks...all part throttle measurments were at 14.7:1 (verified against the wideband in the tailpipe before the cat was hot enough to catalyze anything) I didnt have the wideband hooked up since the stock ecu needed the stock o2 sensor and i only have 1 bung ahead of the cat.

I am still debating on having another o2 bung added to this setup cause i might get away with using the wideband just for tuning and removing it from the car instead of installing it permanently - i say this cause there is a chance the AEM EMS can use the stock o2 sensor for part-throttle fuel correction (man that would be icing on the cake).

 

Right *click* save. This is good to know.

Good Post!!

 

Very nice to have for a reference!

 

weeeeeeeeeeeee. just wanted to put this up since it helped me. I"m seeing a lil less than 700C in full boost in 5th gear. I haven't been able to pass 700C at all on a 2 hour drive so I guess i'm safe

 

Deserves a bump.
