MY stepfather has a 98 civic hatchback, b18c1 (Je Pistons), turbo (~5 psi no boost controller, yet). Does anyone know what a turbo civc's average-max egt should be? Thanks.

 

When I'm cruising on the hwy at about the same speed for about 15min it gets up to about 750 C, but just on and off around town it's between 4 and 6. I have about the same setup as well.

hih

 

It really depends on tuning..

With the stock ecu and injectors, I usually hit ~1400F cruising at 80mph. At idle about 800F, at 60mph about 1250F. On Hondata, and 440cc injectors cruising temp is a bit lower at about 1300..at WOT full boost I've hit 1500F. It is very dependent on tuning, timing (cam and ignition) and plugs, and let's not forget the location of the thermocouple

 

forget a decimal point somewhere?

sensei: 1500F at full boost sounds a little lean (at full throttle) to me. What A/F ratio are you running?

I'd expect to see 1400F or less at full throttle. Granted, I'm used to Rotary EGT's, which almost max out normal EGT/Pyrometer gauges under normal use (maybe 1400F at full throttle turbo, 1500F full throttle N/A, all the way up to 1600F idle/cruise N/A)

Are we talking an in manifold or an after turbo sender? There is a big difference.

 

11.5 all the way to fuel cut (8700rpm) on the dyno. Don't forget that this is a stock R motor..

 

I see about 1500 at WOT also. jdm GSR motor at 8psi. Just tuned and Im happy to report putting down 271hp and 201 tq.

 

Yes... 750C I meant. :fawk:
