1550 pre turbo, but I didn't (and don't ) let it stay there long.....

 

[work2muchplay2little]

Guess I'd better fess up here since I started the poll. I've seen 1695 pre turbo during a 1/4 mile run -- scared the heck out of me, but have had no problems to date, approximately 2 months later. KMFC (Keeping My Fingers Crossed)

Drag racing or on the dyno mine will max out the gauge 1600+. But it isw never there long 1-2 sec max.

It's the EGT's while pulling a LOAD you got to worry about. Drag racing, most of us see over 1600 for a few seconds, which is not a problem. But if that drag race was, say, 5 miles long(racing on the interstate, shame on you ) you might have a problem...

I know of a certain puller who regularly sees over 2200 degrees down the track, without holes in the pistons. No idea how he does it.

Sustained high EGT's while pulling a load for more than a few seconds, can and WILL be a problem in our street trucks. I won't even run at more than 1100 while pulling my 6000 lb. trailer, it's not necessary, nothing to prove to nobody.

My guage only reads up to 1500, and I have barried it. I'm sure that it was higher than that.

 

[MY6EATSV8'S]

over 1800 regularly them pesky little v8 cars. LOL

thow 5 miles is long, and it was only about a mile

anyway I always recomend staying below 1300 for anything more than 15 or so seconds because your on borrowed time then. I know of one truck we all know of that blew up on the dyno. Lasted 15 or so minutes at 1550 degrees. That one ate basically the motors longblock. Besides 15 seconds is usually long enough.

 

[Evan A. Beck]

Adam, 15 sec is plenty long enough, especially when it only takes 11 or so to get down the quarter mile!



HEHEH

1733--sled pull--pre turbo

 

[WadePatton]

I've been past 1400, not sure about 1500. I'll have to train the co-pilot to watch the gauge when I'm racing.



I'm usually doing 50-70mph when the race starts and 100-120 when it ends, so the temps aren't up there long.

 

[Cummins4Life]

Gauge only goes to 1600* and it has been going there pretty quick for 15k.

 

[Jim Fulmer]

Just shy of 1900 pre-turbo... . and yes the motor is still in good shape for 112K.
