Is this normal? The car is running great, but I can't help but notice the egts hitting 1600 at high boost (23lbs). I am using an Autometer guage and probe. It's not the cheap probe either ($99.00) . What do you guy's think? Alex (GSRev) told me his hit's that high as we'll while going down the track.

where did you mount the probe?

#3 runner. It works fine. I just wanna see if it's common for it to hit that high?

how much is your timing retarded when the boost is that high????

turbo Si

19-20 degrees.

QCKGSR

what is your total timing at that boost... should be around 24-26

1600 isn't that hot. I've hit 1800 before on a 4th gear 25psi dyno pull

turbo Si

Yeah but that's one pull. I'm talking about going down the track through 3, 4, and 5th gears at 1600 or more. Isn't 1500 something boing point for aluminum forged pistons?

My egt is right out of the cylinder head and yes it does tag the 1600 mark, but my air/fuels ratio is right on target. So don't go just by your temps. Check your plugs and look for signs of detenation.

Hmmm, I guess your right. Last thursday the car ran great, and the plugs looked good. I don't know, I guess i'm stuck with the thought of something going wrong around that temp.
