Yup ,I am hiting up to 1700F 's ..
Intake tempareture is around 86F.
How can I drop the temparature ?

Water Meth, bigger IC, bigger dp/exhaust, colder plugs, remove under hood foam so engine can breath better, use a more aggressive mix of water in your coolant and run some engine ice or purple ice. I use 70% water, 25% G12, 5% purple ice

Not enough timing and running slightly rich could cause your EGT's to be that high.


EGT readings are used to help dial in the right amount of adv timing.



BTW where is your EGT probe located?

1st question to me is............. Show us your tune...

AFR && timing advance... post it up.

Hey, Mike
You may be correct couse I am only running with 10 degrees for all sites now.
Actually ,Load 20 to 150 is 10 degrees and 150 to 300 goes 9-8-7 ...
This is how the egt is connected;

EGT sensor should be in the manifold.

P.S. Your setup looks nice, I see you went with the small cover 30r. What is your spool like?

Thanks man,
I know ,it more accurate at the 3rd cylinder at the manifold but it should give a idea about the temps right. I don't wanted to risk my turbo.
It starts spolling around 3470rpm. now but the tuninng is not finished. I think it's the best choice for 1.8T displacement.

Dude you only showed us up to 3500, thats not enough.

What about timing?

I dont know why people keep saying that, it isn't like EGT probes fail and they are made to handle well over 2200F deg temps.
