Disappointing ET's

[chvyrkr]

Well, took my truck out tonight, and with the mods in my sig.

My best was 16.92 @ 78 in the 1/4...

Now, the truck was pretty heavy. I didn't unload the toolbox or run it down to 1/4 tank or anything. So, right about 8300 pounds tonight...

I only got three runs, and I was tryin to figure my boost launches out. Usually anything over 3 pounds and I spin, but the last, and fastest, run tonight was with 5 pounds of boost. It was really hot today so I think it was alot stickier than normal.

Also, I couldn't get the 4wd to lock in. I've been havin trouble with the plug under the crossmember, and didn't feel like crawlin under it tonight. I was gonna see how it did with about 10 pounds or so in 4 before I discovered it wasn't lockin in.

That calculates out to about 280hp at the wheels. I was hopin with the money I got into this thing that I'd be around 300-320 but I guess I'll have to wait for injectors, new turbo, and live tuning before I hit that.



So, what're you guys gettin? What do y'all have done that's gettin you over 300?

Over 400?

Forgot to mention my EGT's were close to 1400 every run as well.

Looks like I need to go ahead and replace my IC boots and look for other leaks.

It would be alot faster in 4x4 boosting up to about 15-20. That would make your 60' times way better and a better 1/4 mile, which would make your hp calculation better and maybe around 300.

[GM Duraturd]

What were the 60' times? 1/8 mile?

your low numbers are due to the bad starts, 4x4 boosted launch is what will help you the most

yeah a 4x4 boosted launch will help tremendously. my truck is capable of 12's if i could only do a boosted launch. i ran 13.5 taking off normal.

Yeah, it wasn't goin in though. I just replaced a wheel bearing and I'm not sure about the auto lock hubs after seeing that assembly. Probably gonna switch 'em out to a manual lock, just to get that outa the equation. The clip on my plug to the transfercase broke, so we got a spot of glue on it. I don't know it that was why it wasn't goin in either. I was gettin the light, but no 4wd. Which tells me the transcase worked... But, I wasn't really in a position to tear into it last night.

anytime you are doing a boosted launch ALWAYS lock the hubs in (even on auto hubs) the shock of them locking in on a boosted launch will tear them up
