Competition EGT while racing

[CLAYTON]

What kind of temps have you hit when racing? Is it safe to spike the egt numbers for a second while draggin? The hottest I have hit for a short burst was 1475 how much higher can I go before I melt something? Thanks in advance

Pegged at 1600* at about the 1/8th mile. Its ok just dont hold it there for minutes on end. Electrical tape works well to cover the gauge and keep you from feeling too guilty. :-laf

I have over 100 passes at 14-15 seconds burying a 1600 degree gauge. (1/4 mile) I hope to have a 100 more this year without any damage. We will see

At 680 HP what do you think the temps would be?1600---1800----2000-----? Stupied hot for sure.

I forgot I installed a boost cooler from Snow Performance. The temps did drop below the 1600 degree mark at the track a couple of weeks ago at near eighty degrees ambient.

Just No 2 here... ... Mucho hot... ... ... For a short time.

You guys probably don't have any valve seals left. Every head I have worked on that was subject to those temps, had melted seals. Good news is no cracks.

For me, I have to count how many times the pyro goes arround.



1600* X 2 is about normal for a 1/4 mile

[CLAYTON]

So to hit 1600 -1700 will be ok for short burst?

 

[Turbo Thom]

I read in here that someone hit 1875 on thier x-monitor in the 1/4 and all was well.

Have you had the head off since a 1900 run?????

 

[Jim Fulmer]

Nope, it will all come out soon for a fresh short block and head check, why you worried



Still made 783 yesterday worn out and everything!



Seriously, it's better to keep it at the 1600 range, that's what the water is for! When I do tear it down I'll give a full report.

Thats the reason i put the snow kit on. I kept seeing my gauge go to 1600. I still need to do some tuning. I am in the process of gathering parts for twins to give the temps a real fix...
