Hey guys, I just did a 1/4 mile run tonight, with everthing turned up for the 1st time. My egt's got to 1540*, my boost was@ 38#. This was only for a split second at the end of the run just before letting off the throttle, the boost was at this level for about half the distance. I didn't redo the run in Edge5/BDPP3 again because of this. I know nothing went wrong I was just being extra cautious. So I was wondering, what is too high even short term on this engine?

That's pretty high! I wouldn't do that too often..... You may want to look into getting a 4" downpipe that replaces the 3.5" elbow on the back of the turbo or just get one of the newer elbows that are 4". My temps dropped 100 degrees w/ my Banks downpipe...

or one of the new mega mouth down pipes, 1540 yikes..........

For very short, brief moments you won't hurt anything. I'd definately look into getting a new turbo though.

Hey Big, If you look on the performane thread, you'll see I'm way ahead of you on that one . I'm also thinking of getting water/meth. Seeing how I only get these tems when dragging, a quick shot of 75%h2o/25%meth would give me a little more hp, with a lot of cooling effect.

1540 is not hot at all for a 1/4 mile pass, actually most will agree that EGT's wont really affect anything if the duration is under 20 seconds.

You forgot to include what the time slip said .....

Sorry bout that lets see here, 14.1@102mph, 2.1 60ft. I know I'm a little fast for the times, I can't get a great launch yet having a 2wd and all. As you can see by my 60ft. times. Soebody on here said if a could get a 1.7-1.8, I should get down to 13.5.

The 1st gen in my sig went 13.34 @ 99.5 with a 1.87 60ft. With a set of 31x13.5 Hoosier Quick Time Pros. That was launching at 10psi, didnt even consider breaking the tires loose.

Sorry about getting off topic guys. So considering my 60ft. times, trap speed, and current time at the finish, what do you think I can pull time wise?

I saw 1600° for a real short while when I had the Eliminator. I don't see anything close to that with the Juice. Probably doesn't spike to much over 1400°, which doesn't bother me none.

Its kinda hard to say, what does the truck weigh?

Pre or post turbo EGT's? Replacing the elbow with a 4" unit will considerably lower your backpressure adn EGT's. The 3.5" unit causes almost twice the backpressure as a 4" elbow at the turbo outlet.

Well, I had a little fun yesterday with my new turbo and with both boxes on high I saw a new high for my truck of 1500 degrees!! With my stock turbo I never saw higher than 1350 degrees. I wasn't there for long though. I was at 42psi.... It smokes a lot less now with the new turbo but still gives me a nice plume when I first hammer it....
