What did you do to your NBS GMT800 Tahoe/Yukon Today?

[Scottydoggs]

side note, any one see engine masters last week? they did a fuel challenge. 87, 91 116 and e85. on a pretty built engine.

87 and 91 octane made the same power, liked the same timing. 116 likes the same timing and made a few hp more. same for e85.

so fuel dont matter really they have shown. on a na set up any ways.

What was the compression ratio it all depends on that with high octane gas.You wont see any difference with 9-1 or even 10-1 ratio getting higher than 11-1 and you will def see gains.

i forget the comp ratio, but it was making right around 500 hp on 87 and 91. the corn and 116 was only 10-15 hp better. the dyno overlay of the runs showed the same curves, just 10 hp higher. so for the cost of race fuel and the cost of up grading fueling for e85 for just 10-15 hp just dont seen to be worth it.

What's up with your rear sway bar?

I went with Tony's 2/3 drop with end links and shocks. I have a popping sound that I can't track down. Like backing out of my drive way with rolled curbs or going around a corner in a neighborhood. Everything seems to be solid. Spare tire is secure. I've done the free travel mod. I have also had to get better grade bolts, nuts and washer due to the bushing clamp breaking.

You sure the end links aren’t causing it? My passenger side rear DJM end link had a broken weld that was causing a sound like that, only when going in or out of a driveway.

I will double check, but they seemed OK on last visual check.

Or maybe the bushings themselves are causing it. Are they lubed correctly? How's the condition of the bushings?

Hand washed the truck today and applied a ceramic trim treatment to my rear bumper and step rails. Hoping it lasts a while because the truck looks great.

If it’s Cerakote it seems to last good.

I understand the cost but if your compression is higher than 11.1 and you dont use high octane or e85 your motor is toast.My motor is 744 horsepower and 693 ft lb torque motor only and 11.5 and i run 110 and 93 mixed most of the time.If im running the nitrous i dont dare run 93 only or say bye bye.Between 93 and 110 the difference on the dyno was 21 hp and 26 ft lb tq.Had to throw a pic or 2 in
