I picked up a 2011 pro silber turbo over the summer, went for 3rd ride on Sunday. Went back to default settings and sled pulled strong but hitting 1150-1250 on EGT at WOT in about 4 secounds in 3 feet of pow, tried richin it up but still hitting egt alarm, any ideas on how to lower egt at WOT. Running straight av gas 104.6 octane. 7lbs of boost. air fuel is at 12.2-12.5
2011 800 pro silber

Where are your probes located in the y pipe. I know distance from the cylinder makes a huge difference also does it keep climbing after 3-4 seconds or level out. On my setup up last year it would climb fast and steady out. It also made a difference if I let off the throttle and stab it. Hope that helps, just my 2 cents. Merry Christmas!!

It will keep climbing seen 1320 once and backed right off, has to be close to burn down. Havnt looked to see where probe is I would imagine wherever silber wants it in there instructions. -30 out so havnt looked at sled since Sun. Praying for warmer weather, cant get the bugs out of the sled in this weather 7 feet of snow calling my name.
Read the plugs....when plugs are perfect look at the egt,many factors determine egt readings...ie to much fuel burning in the exhaust pipe egt goes way high as well.....whats your AF reading???
Ok see it , if your running 12.5 and plugs (ngk heat range 9) look perfect and piston top good color I would not even worry about the egt readings be it 1100 or 1400

What octane of fuel you running to run 12lbs of boost, and what are your fuel control settings at. New to the turbo game, but starting to get into it. Thanx for the info.

Are most running 9s for spark plugs? Im running 10 Iridiums. Boondocker setup. Thats just what came in the sled when i bought it
EXACTLY....The 800 CFI-2 and CFI-4 run very hot EGT's, (at least higher than any other motor I have run EGT's on and monitored in sleds).
Noticeably hotter with the stock pistons.
For whatever reason, the sleds I have installed fix kit's in (the Weisco piston and 1/4" cylinder shim kit from MTNTK) run much cooler EGT's along with lower AFR's and have needed less fuel in all throttle ranges than have the stockers. Cooler at idle, mid range, and top end.
In my testing, EGT's, AFR's, plug reads and piston burn patterns prove that the fix kit needs less fuel than a stock oem piston'd CFI.
