Title: High Egt's (newbie)
Post by: mattmey on September 13, 2006, 01:13:32 pm: Hey guy’s

The new 1.6 Td is running good but saw a few issues on the last outing with her. The Egt’s are higher than I like. I noticed it when I am on the power (low to mid rpm range (no tach)) and climbing hills. Had to back out of the throttle when she hit 1200 F pre turbo. I have an intercooler that I know will help but haven’t had time to hook it up yet.

The motor: brand new bearing andbored with oversized pistons. Head redone with new guides, seals, and valve job.

Also I have blocked off the blow off valve, advanced the pump and turned up the pressure on the wastegate to open at 17 psi and rebuilt the turbo. Could I have the pump too far advanced? I advanced it .042” (1.05 mm). I haven’t turned up the fuel screw yet either, figured that would hinder not help.

Any ideas?

Also I think I have read that I shouldn't go over 1200 deg F pre turbo correct?

Thanks,

Matt

Post by: mattmey on September 14, 2006, 09:17:10 am: Oops, should have mentioned the exhaust. 2.5" mandel bend all the way back, no muffler.

Also is 25 psi too much for stock head bolts?

No.
